In contrast,methods used to depress regular interference,especially multiple reflection and surface wave are few.

但在压制多次波干扰和面波干扰方面，目前有效的方法并不多。

Captain Smith was later adopted as an honorary "son" by Powhatan. But that was not the only time that Pocahontas would risk her life and the favor of her tribe to protect her new English friends.

史密斯上尉稍后被波瓦坦收养为名誉上的"儿子"，但那并不是唯一的一次波卡洪塔斯冒着生命危险，及族人对她的喜爱来保护她的新英国人朋友。

Wave energy tends to transfer mainly from the primary wave with highest frequency to other two waves, which isn't completely consistent with the resonant interaction.

能量传递方向主要表现为从高频的主波向次波和生成波转移，这与共振相互作用不完全相同。

A new strategies for restraining harmonics are presented in the paper, the methods adopt the right carrier frequency and the sine wave superimposed a proper three-time harmonics to make it saddle-shaped wave, produce SPWM waveform to control the inverter switching devices for the on and off .

并提出了一种新的易于工程实现的谐波抑制策略，该方法通过正确选择载波频率和在正弦调制波上叠加一个三次波使之成为鞍形波，产生相应的SPWM波形来控制逆变器开关器件的通断从而改善输出波形。

Based on spherical wave theory of point source, the interbed multiples have been effectively simulated by using the reflectivity method.

基于点震源的球面波理论，采用反射率法有效模拟了层间多次波。

Secondary wave: An S-wave, transverse wave, or shear wave.

次波：S-波，横波或剪切波。

Starting from boldine (56), secoboldine (57) was prepared by ring opening at N6 position. Then the resulting secondary amine, secoboldine (57), was treated with various substituted benzaldehydes, to form a series of diarybutanoid-like tertiary amine alkaloids.

以波尔定碱(boldine， 56)做起始物，在N 6位置做开环反应可以得到次波尔定碱(secoboldine， 57)，再用还原胺化反应在二级胺上接上不同的苯醛，可以得到一系列的三级胺生物碱化合物。

Teleseismic conversion and multiple waves recorded by the INDEPTH-Ⅲ seismic array have been used to investigate the crustal thickness and V/V ratios of the central Qinghai-Xizang Plateau.

对INDEPTH-Ⅲ台站的接收函数进行扫描，利用Moho界面产生的转换波和多次波的走时信息，估计台站下方的地壳平均波速比V/V和地壳厚度。

According to Clearbout image condition and the assumption of that the source wavelet is unconsistent with multiwave.

其后推导了适用于叠前逆时偏移的理论公式，在推导过程中应用了Clearbout的偏移成像原理，并假设震源子波与多次波不相关。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
