Why F14 has always been so popular with the world. You don t need to paste in large paragraphs, plea

A powerful radar system, a powerful AIM54 Immortal missile, a variable rear wing, and that classic movie.

The F14's volley and air combat performance are good, and it stands to reason that the US Air Force should be able to equip it, but why did it make another F15? It is said that the development of the F15 was accelerated in order to prevent the Ministry of Defense or the National Assembly from requiring the Air Force to equip ...... F14I don't really understand this.

Needless to say, the F14's powerful performance is not to be said. But you must know that the predecessor of the F14 was a tactical fighter jointly developed by the US Air Force and the Navy, and for various reasons, they parted ways, and the Air Force engaged in the famous F111 on this basis, and the Navy used the core technology of the project to develop the F14So there is no relationship between f14 and f15.

Moreover, the mission requirements of the Navy and the Air Force are very different, and it is impossible for the Air Force to be equipped with a fighter specially designed for the Navy.

The F14 and F15 are both heavy air superiority fighters, and at the same time take into account the interception function. Although it was later discovered that the F14 had the same potential for improvement as the F15, both were originally developed as a purely heavy air superiority fighter and did not consider the later multi-functionality. Therefore, it can be said that the function is completely repetitive, and at the same time the F14 is not lagging behind, although the old United States has a lot of money, but is it not a waste to do so?

F14 and F15 are very different, the functions are seriously different, and it is even more impossible to repeat, the main task of F14 has always been fleet air defense, especially long-range interception of Soviet aircraft and missiles, F15 was first used to stay in the air for dogfight, and later developed into a multifunctional fighter, the mission and F14 are completely different, **Repeated? The Americans will not waste it, and there is a contradiction between the navy and the air force, but the key problem is that the two have too many requirements for fighters, and when the existing technology cannot meet the requirements of the two, they can only develop different fighters separately.

The U.S. Air Force and Navy are bidding for their own aircraft.

Upstairs is really, who told you that the F14 F15 is going to be replaced.

Now the fighter requires supersonic cruise without afterburner.

Stealth: Advanced technologies such as supermobility.

F14 F15 is no longer good.

Downstairs, you see if the current carrier-based aircraft in the United States have been replaced by the F-14 due to its relatively high maintenance costs.

These two are considered third-generation fighters.

Alas

Select the content you want to copy, then change to English, and press "ait+; key, (note the semicolon key), then copy and paste where you need it. You can also replace the two sub-sums of the summary. (There is a space in front of the summary, so when you replace it, you should also put a space in it.)

Don't be nervous just yet! ECG sinus rhythm is normal! It's okay if it's simple!

If you need to make a specific judgment, you can consider coronary CT or direct coronary angiography to check the location of myocardial ischemia and the degree of vascular stenosis! The 24-hour Holter is indeed not captured if it does not have a seizure. Coronary heart disease is still very high in heart disease, pay attention to low salt and low fat diet Quit smoking and limit alcohol You can drink a small amount of red wine, which does have the effect of softening blood vessels, pay attention not to make the elderly too tired, and do not have too many mood swings, prepare a little nitroglycerin or fast-acting heart pills and other drugs at home, and eat a little when you have an attack.

If you take it for a long time, you can consider taking some anticoagulant drugs such as aspirin, and if you don't know if your mother's blood sugar, blood pressure, and blood lipids have problems, it is best to find out.

Disease analysis: 46-year-old women with obvious symptoms such as precordial discomfort and palpitations should first rule out coronary heart disease, plus there is a family history in this area, so it is not possible to be careless, if the clinical diagnosis is insufficient, it is recommended to do coronary angiography.

Now you can only do coronary angiography, or you can do a chest X-ray, it's useless, listen to the doctor.

Since it's about your future, you have to think about it carefully. To be honest, being a chef is very hard, whether it is a Chinese kitchen or a Western kitchen, because a chef is a technical job, and if you master it, then you will have the ability, and the more you master, the greater the natural ability. So to learn this skill is to "concentrate" to learn, you go to those so-called schools, training classes, learning is always just scratching the surface, believe it or not, you really want to learn then you don't regret it, because it will take at least two years or more, of course, if you learn it is also promising, when you first learn, your master will teach you some very basic knowledge, and then gradually let you touch the stove, let you try to cook.

Remember, from the day you enter the kitchen, pay attention to every dish made by the chefs around you, and when you are in contact for a year or so, you will be able to understand how he cooks, what ingredients are used, and how to do it, you have to learn, because there is still a lot of knowledge that the chef will not teach you, because that is their rice bowl, and all the teaching is given to you what they use it for? Usually you have to study quickly, Western food, naturally English is indispensable, although not as strict as when you study, but many words are proper nouns, you want to learn a deeper level or have to self-study, yourself through the Internet, access to information, etc., and most of these books and related ** are in English, so you think about it yourself. After mastering cooking, you also need to learn a little bit of photography, because a good chef not only cooks, but also has to learn to take pictures of your cuisine.

There is also art A little bit of color matching, because many times the same dish is not the same dish on the plate, and the feeling is also very different, and the guests will naturally choose to look good, if a dish looks disgusting, then who else wants to taste it, that's pretty much it. If you want to learn, go to some well-known cafes, 5-star hotels, and the hotels must also be well-known, and the scale should be more than 1,000 people. That's pretty much it, I hope it helps!

I almost forgot to ask you, do you want to learn to cook or pastry? Because these are two completely different techniques, Western food is divided into hot dishes and cold dishes, and hot dishes basically need to be fired, such as some beef parties, soups and the like. Cold vegetables are a sketch of plants, dipped in killing, etc.

There are also private rooms that specialize in bread, such as croissants, square buns, and the like. The bakery specializes in making small desserts such as pastries. If it's a better hotel, there is also a special chocolate room.

That's pretty much it, if you have any questions, you can send me a message, and I'll let you know if I know.

I used it, fake, it didn't work! It's so expensive to change cigarette cartridges! I smoked an e-cigarette, and I was smoking a real cigarette, and I still feel that the real cigarette is stronger! Don't be fooled.

Inverter air conditioning is to change the speed of the compressor to achieve a balance between the refrigeration capacity and the environment, in fact, the original intention of the invention of inverter air conditioning is for comfort, and in China's low consumption level of home appliance market to save electricity is also a misleading.

The inverter air conditioner does not reach the set temperature when the compressor works at full speed, its work efficiency is consistent with the fixed speed air conditioner, after reaching the set temperature, the inverter air conditioner enters the low-speed operation, so that people are in a stable and comfortable environment, and the power-saving effect has appeared! Unlike fixed-speed air conditioners that control the temperature by constantly starting and stopping, the actual temperature fluctuations are relatively large, and I have used inverter air conditioners for more than ten years to fully enjoy the life enjoyment brought to me by inverter air conditioners.

Household appliances are used to improve the quality of life, so comfort comes first, and power saving comes second.

The difference between inverter and constant frequency of air conditioner: mainly in the different power supply methods.

1. The working voltage of the inverter air conditioning compressor is to convert 220V into three-phase power supply to 380V. In order to improve work efficiency, so as to improve the cooling and heating effect of air conditioning.

2 Due to the use of inverter technology, the air conditioner automatically adjusts the power according to the room temperature, once the room temperature reaches the set temperature, the air conditioner will work with the minimum power, maintain a constant temperature (constant temperature refers to the set temperature value), reduce power consumption, and save electricity.

3. Due to the use of inverter technology, the working noise of indoor and outdoor units is much less than that of fixed-speed air conditioners, and the comfort is better.

Once the temperature reaches the set value, the machine will stop working and the temperature will rise and then start again at maximum power. This way of working is very current-intensive, so it is more labor-intensive and noisy.

It must be easy to spread the frequency conversion, and the frequency conversion is very energy-saving, but it will definitely be more expensive, it's very simple.

The frequency conversion is good, the voltage is high, and the power is saved.

The power saving of the inverter is better than the invariant frequency.
