What should I do if I always only score 82 points in the driver s license subject 1?

It's okay, don't be discouraged! Taking the 82 test proves that you are quite strong, but you just lost 8 more points. Get a few more questions right and you've got it right.

Find a driving test book, and then do the mock test questions, until you do more than 90 points out of ten tests, one of seven or eight times, focusing on memorizing the wrong questions. It will be easier to get by. I wish you a speedy passing of your driving test.

Get your driver's license early!

First, brush the questions twice and practice the wrong questions more.

Second, be careful about the questions and look at the intentions of the diagram and the questions.

Third, don't be nervous during the exam. Just play normally.

Fourth, read more questions that are easy to make mistakes before the exam.

Fifth, remember some specific knowledge points.

If these five articles are done, it will be no problem to pass.

This requires you to do more questions. In general, a score of 90 is required to pass. Acquire more knowledge of transportation. You need to memorize it so that you can pass the test.

Discharge cooling is another type of convection cooling. Unlike regenerative cooling, the coolant used for exhaust cooling absorbs heat to the thrust chamber and is discharged out of the combustion chamber instead of entering the combustion chamber to participate in combustion. Direct drain coolant reduces the thrust chamber specific impulse, so the coolant flow for drain cooling needs to be minimized while only using drain cooling at the outlet section of the nozzle that is relatively less heated.

There is also radiative cooling, in which the heat flow is transferred from the combustion products to the thrust chamber, and then the heat is radiated by the thrust chamber wall to the surrounding space. Radiative cooling is characterized by simplicity and small structural mass. It is mainly used in the extension section of large nozzles and the thrust chamber of small thrust engines using high-temperature resistant materials.

When cooling in the thrust chamber of the tissue, a relatively low temperature liquid or gas protective layer is established on the surface of the thrust chamber wall to reduce the heat flow to the thrust chamber wall, reduce the wall temperature, and achieve cooling. Internal cooling is mainly divided into three methods: internal cooling (shield cooling), membrane cooling and diaphoretic cooling of head tissues. After the internal cooling measures are adopted in the thrust chamber, the mixing ratio near the wall of the combustion chamber is different from the optimal mixing ratio in the central area (in most cases, the near-wall layer rich in fuel is used) due to the need to reduce the temperature of the protective layer, resulting in the uneven distribution of the mixing ratio along the cross-section of the combustion chamber, so that the combustion efficiency is reduced to a certain extent.

Membrane cooling is similar to shield cooling in that it cools the thrust chamber wall by establishing a uniform and stable coolant film or air film protective layer near the inner wall surface, except that the coolant used to establish the protective layer is not injected by the injector, but is supplied through a special cooling belt. The cooling band is generally arranged in a cross-section of the combustion chamber or the convergence section of the nozzle. There can be several cooling bands along the length of the combustion chamber.

In order to improve the stability of the membrane, the coolant often flows through the gaps or small holes in the cooling belts, and when sweating is used, the thrust chamber wall or part of the inner wall is made of porous material with a pore diameter of tens of microns. Porous materials are usually sintered with metal powders or pressed with metal mesh. In this case, the number of pores per unit area is increased by making the micropores in the material as evenly distributed as possible.

The liquid coolant penetrates into the inner wall, creating a protective film that reduces the density of the heat transferred to the wall. When the flow rate of liquid coolant used for sweat cooling is above a certain threshold, a liquid film is formed near the wall of the thrust chamber. When the coolant flow rate is below the critical flow, the inner wall temperature will be higher than the coolant boiling point at the current pressure, and some or all of the coolant will evaporate, forming an air film.

In addition to the above thermal protection, there are other thermal protection methods such as: ablation cooling, thermal insulation cooling, hot melt cooling and composite protection of chamber walls. 3. Thermal protection scheme of high enthalpy gas generator Based on the above methods and the actual situation, the thermal protection method of high enthalpy gas generator is obtained.

The combustion chamber of a high-enthalpy gas generator differs from that of a liquid rocket engine, eliminating the front thrust chamber part, making its structure simpler and more effective. Then, the thermal protection involved is the thermal protection part of the combustion chamber wall. As the fuel enters the combustion chamber, it quickly decomposes and releases large quantities.

The method of scoring more than 80 points in subject one is as follows:

1. Formulate a detailed study plan and make a detailed study plan, which can improve learning efficiency, and is more conducive to quickly and comprehensively grasp the key points of knowledge, the study plan can be to practice sequentially to master the basic knowledge, and then mock the exam, repeat the practice several times, and strive to stabilize the score above 95 points, so that the probability of passing the exam is relatively large.

2. Strengthen practice, especially to enhance memory. Because there are still a lot of knowledge points in the subject 1 exam, students need to repeatedly brush up on the questions in the question bank and practice more, especially some wrong questions, which need targeted practice, so that it is not easy to make mistakes during the exam.

3. Learn to summarize and summarize, and put some relatively similar or regular content together, so as to facilitate memory and understanding. Through this method, the learning efficiency can be effectively improved, and the learning time can be greatly saved. Guess the pose.

4. Adjust your mentality, your mentality is very important in the exam process, too nervous, too anxious, too flustered will easily lead to failure in the exam, so you should adjust your mentality before entering the exam room, don't be too nervous, cheer yourself up, and believe that you can.

Exam process:

1. Obey the arrangement of the staff and receive your own learning file in the waiting room.

2. Bring and present your ID card to accept the review of the invigilator police.

3. You must turn off your mobile phone when entering the test area.

4. Do not make loud noises when entering the test area.

5. Textbooks are not allowed to be brought into the examination room (or put in a bag).

6. After the test, the ID card should be collected and kept, and the file should be handed over to the "Certificate Delivery Window" in front of the examination room.

7. Students who have passed the examination will sign at the exit of the examination room under the guidance of the staff and leave the examination room.

8. Students who fail the test can leave the test room and wait for the staff of the driving school to inform them of the make-up test time.

The subject has been hung up with a score of 89 once or twice, and you have to retake this test.

The driver's license that has been delayed for several years is finally going to take the subject one, haha Friends say it's very simple, but there are still people who have failed to take the test.

The total time of the subject 1 exam is 45 minutes, and the exam paper consists of 100 questions, the question types are true/false questions and multiple-choice questions, with a full score of 100 points and 90 points to pass.

In addition, there is no limit to the number of appointments for subject 1, and you can make another appointment after failing the course, and you can pass the exam until you pass.

Subject 1 refers to the driver's theory test, which is conducted at the DMV, and is a licensing test that must be passed by the driver's license applicant. The content of the test includes driving theory, basic knowledge of road safety laws and regulations, traffic signals, traffic rules and other basic knowledge, plus local regulations.

The results of subject 1 are issued on the spot, the total score is 100 points, 90 points and above are qualified, you check the online is 69 points, and there is no function to check the results on the Internet, and you can't check it in the traffic management 12123, and if you fail the exam, it will show that you can't make an appointment for the exam, and you need to make up for the exam.

When you submit the test paper, you can display the results, and then you can leave the test room after signing and confirming the results, and if you are not sure, you can check the results in the driving test file.

Subject 1 exam results do not need to be queried. As long as you press the "Submit" button and then press the "Confirm" button after answering the question, the test result will be displayed immediately. Note: After passing the test, you will also get a driving skill test certificate (if you don't have it, you will fail the test).
