The direction of travel and strengthofshock waves are influenced by wind, speed, and direction, and by air temperature and pressure.
冲击波的行进方向和强度受到风、飞行速度及方向、气温和气压的影响。

As many as four-fifths of all the cells in the electric eel's body are specialized for generating electricity, and the strengthof the shock it can deliver corresponds roughly to length of its body.
在电鳗的身体中，五分之四的细胞都是专门用来发电的。电鳗能释放的电流强度大体上与它的身体长度相一致。

Some characteristics of the rolls, such as strength vs. Thermal shock, tensile strength and contact fatigue strength, influence spalling. Thus, strength was investigated as a hardness parameter.
