查询词典 oscillations

It was found that in the DC bias electric field, when the relaxation time of the hot-electrons in the electron-electron and electron-phonon interaction process is longer than the carrier life, the photoconductivity oscillation can be caused by the change of mobility in the process of optoelectronic transport, which is the main cause for the output electrical pulse to show oscillations.

分析了开关体内载流子的微观状态和输运过程，在直流偏置电场作用下，开关体内的热电子在电子-电子、电子-声子相互作用过程中，当它们的弛豫时间大于载流子的寿命时，光电子的输运可通过迁移率变化引起光电导振荡，这是开关输出电脉冲出现振荡的原因。

But until now, no one has been able to pinpoint the cause of these oscillations.

但之前一直没有找到这种周期变化的原因。

Results Ca 2+ oscillations could potentiate the response to a hormonal stimulation.

It discusses testing means and testing equipment to oscillation, puts forward disposal means to oscillation data, fetches oscillation model of vehicle plane, does predigestion and coupling to all kinds of oscillations.

对振动的测试方法和测试设备进行了论述，提出对振动数据进行处理的方法，推导出车载平台的振动模型，对各种振动进行了相应的简化和耦合处理。

The primary pressure maximum and minimum occur during the daytime at 0900L and 1500L, respectively, while the secondary maximum and minimum during the nighttime at 2200L and 0400L, respectively. Additionally, the amplitude extremes of the primary pressure oscillations are larger than the secondary extremes.

每日最高气压和最低气压皆在日间（0900L和1500L）发生，因台北盆地日间受太阳辐射增温之影响，其气压振幅较大，且两者的相位也比一般中纬度地区提早1小时。

Also, the voltage on the primary winding reverses direction during the operation of the circuit but this too, does not have any effect on the oscillations.

此外，太初级绕组电压反转方向，在电路的运作，但是这一点，没有任何振荡的影响。

According to the resonance mechanism, power disturbance of prime mover can arouse power system forced low frequency oscillations.

文中根据汽轮机功率扰动引起电力系统低频振荡的共振机理，研究了汽轮机功率变化的原因。

But internal reflections an the boundaries of active medium can drastically enhance the onset of ASE, particularly if these reflections lead to a close path, i.e., a ray that is reflected upon itself. In the case, we have a strong feedback mechanism and as soon as the gain in the laser medium exceeds the reflection losses parasitic oscillations will set in.

但自发辐射的存在使得放大器工作介质会在信号光到达前开始发射激光，并且工作介质边缘的内反射能显著增大ASE的发射，尤其当这些反射能导致产生封闭路径时更是这样，当激光介质内的增益超过损耗时，就建立起寄生振荡。

Strong oscillations can occur in the residuals as the number of terms is increased.

随着次数的增加，剩余时差会发生强烈的摆动。

According to the frequency formulae of the two kinds of oscillations, the relation between depth of cavity and speed of flow for cylindrical cavity is derived, when the coupling resonance condition is satisfied.

根据文中得到的两种振荡的频率公式，还导出了圆柱形腔满足耦合共振条件时腔深和流速之间的关系。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
