13号车钩(下作用)为什么会发生自动开锁?

答案

参考答案:

主要因为下锁销上端突起及钩头内防跳台铸造的形状尺寸不符合要求,由于失去了防跳作用,在运行中受振动,就引起了自动开锁,为此,在13号作用式车钩上还增设了二次防跳装置。

     Much has been written about body language during a job interview. Experts from across many fields

are full of advice on just how to present your best performance in an interview using conscious (自觉的)

body language choices. While many of these experts say there is a "secret" system for making the most of

an interview, the reality is that most of them focus on a few general types of behaviors that have the

greatest effect during a job interview.

     Entering the interview location - Your walk should be active and confident. Keep your shoulders

straight, head up, and make eye contact with the people around you. Maintain (保持) an active facial

expression and be confident when shaking hands and greeting people to whom you are introduced.

     During the interview - Sit in a straight and attentive posture. Never let your shoulders drop or your head hang down, but rather keep your head up and make eye contact with the interviewers. Don't play with any papers or notes you have in front of you, and don't lean (倚靠) your arms heavily on the table. Keep your body position open and make eye contact while listening to and answering questions.

     Leaving the interview location - No matter how you feel about your performance during the interview,

carry yourself with confidence till you leave the interview location. Be confident when shaking hands and

making eye contact as you say goodbye, and keep your body posture straight as you walk all the way to

your car.

     Remember, the more you make active and confident body language a part of your daily life, the more it becomes a habit that follows you wherever you go.
