估算有机物正常沸点的基团贡献法比较与评价
In the point of view of molecule force theory, the physical regularity reflected in physical phenomenon of the normal boiling point for open chain, aromatic, alicyclic hydrocarbons and carboxylic acids, a new theoretical equation of the normal boiling point for them is proposed.
应用分子力学理论揭示出烃类和羧酸等的正常沸点Tb这一物理现象中的物理规律性,从而提出其正常沸点的理论方程,物理意义明确,经用链烃,环烃和羧酸等的298个纯质的实测值验算,平均误差为0。
The probability of a ship-based missile falling on deck after failed ignition
舰载导弹未正常点火下落砸中舰体概率研究
Thus, during a normal light-up there is a blade temperature charge of about 30 degrees/sec.
于是，在正常点火时，叶片温度的变化率约为30度／秒。
I do hope the train is on schedule.
我非常希望火车能正点。
Jupiter is still cooling and shrinking, at an estimated rate of 1 mm/yr.
正常的持续稳定核聚变点火温度约400万度左右！

"Will the train keep on the lines?"
火车能正常运行吗？
The train departed from the capital at 12 o'clock
火车于12点正离开首都。
timing of engine
发动机正时点火调整
The train pulled in right on time.
这列火车正点到站.

" You're fine. Have a drink of water."
“你一切正常，喝点水吧。”
"Just try to relax," he said, "Everything is all right.
“尽量放松一点。 一切正常。”

FOR INTERMITTENT 2ND GEAR OPERATION AND THEN A SUBSEQUENT RETURN TO NORMAL OPERATION WITHOUT CYCLING THE IGNITION KEY
对于间歇的第二档操作，及随后的不用旋转点火钥匙就能返回正常操作
"Improper combustion, due to a rich mixture, defective ignition system, loss of compression in the engine, a cold engine, and so forth, will result in carbon deposits on the exhaust valves."
因混合气过浓、点火系统有故障、发动机内压力损失、冷机等导致的不正常燃烧都会形成气门积炭。
Whenever you bought a car, you would have to reorganize the ignition for a few days before it worked.
每次你买了车，都得先花上几天时间改装调试点火开关，然后它才能正常工作。
