Global changes of the heatbalance between the sun and the earth are influenced by variations in the solar constant . 太阳和地球间热平衡的全球性变化是太阳常数的变化引起的。
in the case of carbonic acid, the ionization constant of is much smallar than the for acetic acid. 至于碳酸，电离常数为比醋酸的电离常数小的多。
The permeation constant of gases through metals is negligible except for hydrogen through palladium or iron . 除了氢气能穿过钯和铁之外，气体穿过金属的透气常数是可以略而不计的。
In this work, the copper binding capacity of several complexing agents of known stability constants was determined . 在这一工作中，测定了几种已知稳定常数的络合剂对铜的束缚能力。
The association chain implied is general reactivity, delocalization, heat of reaction, activation energy, velocity constant . 和该量有牵连的因素是一般活性，离域作用，反应热，活化能，速度常数。
is the plane-wave propagation factor in the uppermost medium and w is the propagation factor of the surface wave. 是最上部介质中的平面波传播常数，而w是表面波传因子。
We could attempt to get around this difficulty by initially assigning the arbitrary value to another of the unknowns rather than to xn. 开头对另一个而不是Xn的未知数指定为任意常数，能试图避免这个困难。
