A small amount is found in silicon-beryllium yttrium and molybdenite, which have extremely high melting points. Elemental Uses: Mixed with tungsten or platinum to make filaments on mass spectrometers.

The addition of a small amount of rhenium to the alloy can increase the hardness, so it is used to make metal parts that can withstand friction for a long time. Informatics competition term: re:

Abbreviation for runtime error. One of the ratings of the online judge of the informatics competition**. This kind of error can be avoided as much as possible, and 99% of the time the array is out of bounds--- either underflowing or overflowing, with the latter being the majority.

The solution is: get used to carefully reading and estimating the amount of data in the problem before writing the program, and open enough length for the array (it is not necessary to be as large as possible, but at least it should be enough, and if it is not enough, it must be re, unless the test data of the question is much more watery than the description, and those questions are not done).

Or re-meaning.

re means cause and is an abbreviation for reply.

reply1, meaning: v ；Reply; Response. n. ；Reply;

2. Usage. In 1385 it entered the English language, derived directly from the Old French replier, which means, to respond; Originally derived from Latin.

2. The prefix re- indicates the following four meanings:

It means to go back or backwards. For example: return, return, recall, retract

It means again, again, repeatedly. For example: review, reunion, restart, reconstruction

It means the opposite, the opposite. For example: rebel, reverse, resist

It means more meaning, and is used to strengthen the tone, which is used less. For example, "recommend" has the same meaning as "commend", but with a stronger tone.

The meaning of repeating. Analysis: The English word for repetition is repeat, because the English prefix re means to do it again, such as rewrite, reset, retie, reunion, retranslate, and reshipment.

is a complex number of real parts.

1. Reynolds number.

re is also the mathematical symbol for Reynolds number.

A dimensionless number that can be used to characterize the flow of a fluid.

The formula is: re= vd, where v, , and are the flow velocity, density, and dynamic viscosity coefficient of the fluid, respectively.

d is the length of a feature. For example, if a fluid flows through a circular pipe, d is the diameter of the pipe. The flow of a fluid that can be distinguished by the Reynolds number is laminar flow.

or turbulence, which can also be used to determine the resistance experienced by an object to flow through a fluid.

For example, for the flow of a small ball in a fluid, when res are much smaller than "1", their resistance f=6 r v (known as the Stoke bucket finger keys formula, when res are much greater than "1", f = and irrespective of .

2. Element symbol: rhenium.

Mix with tungsten or platinum to make a mass spectrometer.

metal parts.

3. BBS common expressions.

re, the abbreviation of reply, is a common phrase on BBS, indicating follow-up, approval, mostly used for irrigation.

4. The radius of the earth.

RE, which is the abbreviation of the radius of the earth, is often used as a unit of distance, and is used more in astronomy, geography and other fields. RE is usually 6370 km.

5. Reverse engineering.

RE (reverse engineering), also known as reverse engineering.

Reverse engineering refers to the process of measuring the physical object or model with certain measurement methods, and reconstructing the CAD model of the physical object through the three-dimensional geometric modeling method according to the measurement data.
