What is the definition of a second?

There are 2 meanings of seconds, one is that the French sect uses skills to call seconds, and the other means that it is a second kill, that is, the end of a round!

You or your own summoned beasts can inflict attacks on many enemies with spells.

Instant kills, in all senses, are the killing (or killing) of an enemy unit in a very short period of time

But it's not strictly controlled within one second, as long as it's a surprise quick kill, it's basically counted as a second kill.

- quotes [words x years ago].

There are two concepts in the dream.,The first is like the first floor said to kill people.,The second is to use spells to hit two or more monsters.,For example, than LG, you can use up to 7 seconds.,WM can be up to 5 seconds.

What to look at if it's a sect"The spell sect, the dragon palace and the demon king's group method, one meaning is to kill in seconds, that is, the end of a round!

It is called seconds to attack the enemy, and second 1 second 2 is to attack the enemy 1 and two.

Divide a minute into 60 equal portions, and each portion is called a second. Ha ha.

Seconds should refer to the spell sect, the dragon palace and the demon king's group law,

Seconds are the spells of the sect that can be hit several at a time.

In addition, one second can be divided into 100 equal parts, and each part is called a microsecond!

One microsecond can be divided into 10 equal parts, and each part is called Hao second!

That is, if you hit a few in one round, it is called a few seconds!

Just one moment, one moment to hang him up.

When the caesium-133 atom is located at sea level and in the non-perturbated ground state, the radiation frequency δ Cs corresponding to the transition between the two ultrafine energy levels is expressed in Hz (i.e., equal to S-1), and the fixed value is selected 9192631770 times to define the second.

The cesium atom mentioned in this definition must be stationary at absolute zero and be in an environment of zero magnetic field and sea level. The seconds defined in such cases are equivalent to the seconds defined in the astronomical almanac.

Definition of seconds: When the cesium-133 atom is in non-perturbationGround stateWhen the radiation frequency δ Cs corresponding to the transition between the two hyperfine energy levels is expressed in Hz (i.e., equal to S-1), a fixed value 9192631770 times is selected to define the second.

Units of time. The second is the International System of Units.

The basic unit of time.

The symbol is s. It is also sometimes referred to as SEC. by an abbreviation.

The origin of the second

Before the Han Dynasty, "Shi" referred to the season, and "Yiyi" was equivalent to the current season. There are four seasons in a year, so a year is also called "four hours".

After the Han Dynasty, "shi" no longer means seasons, but is used to represent the unit of calculating time. At that time, people divided the day into 12 "hours" equally, and "one hour" was equal to the current two hours, and people used to call this "hour" "hour".

In some classical books, we often see the word "hour", and many people mistakenly think that an hour is an hour now, but this is not true. Like the ancient "one watch day" that denotes the night time.

The "more" of "second watch" refers to the hour, and the first watch to the second watch, and the second watch to the third watch are all separated by two hours.

Later, the day was divided into 24 equal parts, and each part was still represented by "hour". At this time, "one hour" is one hour now, which is only half of the "one hour" or "one hour" in the past (after the Han Dynasty), and the time referred to is shortened. Then, the hour is divided into 60 equal parts, and the time of each part is called 1 minute, and the time of 1 minute is divided into 60 equal parts, and the time of each part is called 1 second.

In this way, the hours, minutes, and seconds are determined.

As tools for accurately measuring time continue to improve, it is natural to doubt the accuracy of the unit of time itself. The unit of measurement of time is mathematically defined, a second is 1 60 minutes, a minute is 1 60 hours, that is, an hour is 1 24 days, and a second is equal to 1 86400 in a day. But in fact, because of the speed at which the Earth is moving and the distance from the Sun, a solar day, the period from noon to noon, is not all the same.

Prior to 1960, CIPM (World Conference on Weights and Measures) was based on the Earth's rotation and defined a second as one-86,400th of an average solar day. That is, 1 second 1 86400 average solar day. However, the Earth's rotation is not stable and can change due to the gravitational pull of other stars.

1960 In 1967, CIPM was changed to the year 1900 as the mean solar year based on the revolution of the earth. The definition of a second has been changed to one second as one-tenth of an average solar year.

The 13th General Conference on Weights and Measures held in 1967 chose the transition of cesium atoms as a new definition of seconds, that is, the time elapsed by the 9,192,631,770 cycles of the cesium atom isotope ground state hyperfine energy step transition, set it at 1 second (called atomic seconds), and the new definition of seconds brought the timekeeping method into the age of atoms, and this definition has been maintained to this day.

One minute and 60 seconds. (You still want to ask about the seconds of the "flash sale"?) , that's what it means to be defeated in an instant).

I believe that for each of us, we are very much looking forward to love, because we all know that love is happy and very beautiful.

Especially when we meet someone we like, then many people will be more serious, and they will work harder to care about themselves and the people they like. Because they believe that it is under their constant care and love that they can better be with the people they like, and they will be able to have a happier and sweeter love.

We see when we meet someone we like. A lot of people will be very proactive. Even they will take the initiative to send messages to each other.

We all know that sometimes we send messages to each other, and they may not reply for half a day. But some of them may have sent us a message, and he would reply in seconds. So some people wonder if the second back is really just like a person's performance.

Maybe for a small number of people, they don't think that the second reply message may not really like us. Although he may not like us, we at least know that he actually values us more. Because only those who value us will respond to our messages quickly, and those who don't pay attention to us, they will definitely not reply to our messages immediately.

Of course, in fact, if we send a message, the other party can reply in seconds. I believe that for most of us, we can still be sure that the other party likes us very much, because if the other party doesn't like us. He probably didn't get back to us that quickly.

And we also know that people who like us, they care about us very much, as long as they see any information from us, they will definitely reply to you in seconds.

Therefore, I believe that for everyone, they are very much looking forward to love, because love is happy and very beautiful. When we see people who like each other, they message each other as well. People who really like us, if we send a message, they do reply to our messages in seconds, because they care so much about us and that's why they care about us.

Therefore, they will reply as soon as they see our messages, and I believe that this will allow us to better feel each other's love, so that we can have a happier and better love in the end.

The second means the unit of calculation of time, one-sixtieth of a minute: table. Needle.

秒", a standard first-level character (commonly used character) in modern Chinese, pronounced miǎo in Mandarin, was first seen in the Qing Pin Shuowen, and belongs to the shape and sound characters in the Six Books. The basic meaning of "seconds" is the mango on the seed shell of the grain, which is extended to be subtle, tiny, such as seconds; The meaning of the extended answer is the unit of calculation of time, one-sixtieth of a minute, such as a stopwatch and a second hand.

Detailed interpretation: 1. Shape and sound. From He, less sound. Original meaning: Hemang.

2. The angle is 1 60.

3. Another example: seconds suddenly (seconds are hemang, suddenly are filaments, metaphorically fine); End of seconds (tiny).

4. The name of the unit of measurement.

5. Time 1 60;Refers specifically to the centimeter-gram-second system of time.

6. Same meaning.

Seconds, Hemang also. - Sayings.

Calculations are fleeting. - Han Shu Shu Shu Xia.

Example sentence:

1. Because in some races, once the stopwatch starts timekeeping, the game must be played without human guidance and control.

2. The information is extracted from the data carried by the inbound events and is included in metrics, counters, and stopwatches, which represent the business metrics collected by the monitoring context.

3. The sports set has all the fitness items, such as pedometer, bicycle record, running cheat step record, compass, alarm clock, stopwatch and sports-related news subscription.

4. Before that, Evra also had a heated argument with the team's physical trainer, Robert Duverne, who then threw his stopwatch far on the ground and walked away.

5. Record the time throughout the day when you start or finish an activity, consider using a stopwatch to record the time interval of each activity.

The original meaning of the second is the mango on the sub-shell of the Guzhou eggplant species. By extension, subtle, tiny. It is also extended to the unit of calculation of time, one-sixtieth of a minute.

秒 (pinyin: miǎo), a first-level general standard Chinese character in Chinese. "Seconds" is a phonetic word, from He, less sound. The unit of time, the second (second), is the basic unit of time in the International System of Units, and the symbol is s.

Definition of time unit seconds: When the cesium-133 atom is located at sea level and in the non-perturbated ground state, the radiation frequency δ Cs corresponding to the transition between the two hyperfine energy levels is expressed in Hz (i.e., equal to S-1), and a fixed value is selected 9192631770 times to define the second.

"Seconds" is a phonetic word, from He, less sound. "He" is used as a form to express its original meaning related to grains. The ancient sound of "less" is the word "book" and "night", which seems to be far away from the initials of "second".

The original meaning of "seconds" refers to the fine hairs that grow first from rice, wheat, etc. In ancient characters, the characters "little" and "small" are differentiated, and "orange beats are less" and "miao" also have a cognate relationship, which is extended to the units of length and weight. It is also extended to the unit of time, which refers to one-sixtieth of a minute.

It can also be used in angular units, which refers to one in three hundred and sixty degrees of one degree.

The second is the basic unit of time in the International System of Units. SI prefixes are often combined with seconds for more subtle divisions, and it is customary to use the 60 base minute, hour and 24 day as an extension of the second.

In the League of Legends game, exiting the game when choosing a person is called a second. In a match, kill the opponent after playing a set of skills, also known as seconds.

I usually take the board and the 2-point board when I estimate that the good ball is about to bounce up and shine at the same time, press d to jump, of course, it is not excluded that individual 2-point boards will be relatively high and can't get it, and sometimes I can't react Oh anyway, the general meaning of the second board is to take it away at the moment when the ball is shining, and don't give others a chance.

As long as the board falls off the basket, it is a second board for C.

When the caesium-133 atom is located at sea level and in the non-perturbated ground state, the radiation frequency δ Cs corresponding to the transition between the two ultrafine energy levels is expressed in Hz (i.e., equal to S-1), and the fixed value is selected 9192631770 multiple to define the number of seconds circle.

The cesium atom mentioned in this definition must be static at absolute zero and be located in an environment of zero magnetic field and sea level. The seconds defined in such cases are equivalent to the seconds defined in the astronomical almanac.
