谐波曲线 meaning in English

harmonic curve

The results show that the temperature variety in prestress concrete could not been neglected . the main factors that affect the temperature distribution had been analyzed basing on experiment results and much datas of environment variety , and provided a simple curve about periodical variety environment temperature
在现场试验研究和其它的环境温度的大量实测资料的基础上，对影响预应力混凝土构件内部温度分布的主要因素进行分析，提出了周期性变化的环境温度可在数学上简化为一条简单的简谐波曲线。
In chapter four the effects of a static electric field and different initial states on hhg are studied . under an additional electric field the spectrum exhibits a double - plateau structure . furthermore , the ionization probability and hhg also behave differently when the hydrogen atom is in different initial states
在第四章中，我们研究了外加平行静电场以及初态的不同对电离率和高次谐波的影响，发现附加一适当的静电场会使谐波曲线呈现一双平台结构，电离率会随着电场强度的增大而增大；当氢原子在初始时刻处于不同态时，根据选择定则，谐波曲线和电离率都会有较大差别。
