必须注意到,电流是与每次电阻减少成比例地增加的.Strength in cutting-tool material is not always proportional to hardness.
切削刀具材料的强度并不都是与硬度成正比的.The value of a fraction is inversely proportional to that of the denominator
分数值与分母值成反比例.The values for the stresses are assumed to be linearly proportional to the pressure
这些应力值被假定为与压力成线性比例关系.The elongation of a body in tension above its no-load length is directly proportional to the stretching force
物体在拉伸状态下,其伸长量(相对于无负荷时的长度)与拉伸力成正比.
