换句话说，任意时刻A物质的浓度等于初始浓度，减去常数乘以时间。

In other words, the concentration of at any time is given by the initial concentration, t minus the rate constant times time.

并讨论了原子的初始相干性及原子间的耦合常数对该压缩的影响。

The influences of the initial atomic coherence and atomic coupling constant on the squeezing are discussed.

模式所需的输入为初始土壤含水量、土壤物理常数、作物播种期、逐日平均气温、相对湿度和降水量。

The desired input parameters were soil physical constants, crop 's developmental date, initial soil water content and daily air temperature, relative humidity and precipitation.

So let's actually just simplify this to the other version of the Rydberg constant, since we can use that here.

除以n初始的平方，我们把它简化成,另一种形式的Rydberg常数。

So, if we start instead with talking about the energy levels, we can relate these to frequency, because we already said that frequency is related to, or it's equal to the initial energy level here minus the final energy level there over Planck's constant to get us to frequency.

如果我们从讨论能级开始，我们可以联系到频率上,因为我们说过频率和能量相关,或者说等于初始能量,减去末态能量除以普朗克常数。
