查询词典 half angle

Digital simulation results show that when a step change in firing angle occurs, the first positive half-cycle time of VC will change suddenly and the subsequent electromagnetic transients appearing in the TCSC circuit will lead to overshoot and oscillations in the TCSC impedance. The range and duration of the oscillation will depend on the synchronization modes used and the manner in which the step change is introduced.

发现脉冲触发角阶跃变小时，电容电压的周期时间也突然变小，使得TCSC的导通角不会随着触发角的阶跃变化而发生突变，而是经过一个振荡过程逐渐达到稳态值，进一步揭示了电容电压同步方式下阻抗阶跃特性会出现过冲和振荡现象的原因。

在第一部分有关脑侧化功能的实验裹，研究者利用视野控制法呈现「中文词」、「英文字」、「黑方块」、和「完形图」於受试者的「右视野－左脑」及「左视野－右脑」，以考验「左脑处理分析性、系列性语文讯息，而右脑处理整体性、同时性图形空间讯息」的说法是否为真。

The conclusion is drawn from the simulations that the secondary electrons will go out from the sample surface more easily with the decrease of the half cone angle of tip and the increase of secondary electron energy, tip-sample separation and the distance of the emission site away from the point directly under the tip.

模拟的结果发现针尖半锥角越小、次级电子能量越高、针尖样品间距越大、次级电子出射位置离针尖正下方越远则越有利于次级电子的逸出，此外通过栅网与一个平行于样品表面的地电极的共同作用，会对次级电子产生聚焦作用。

结果表明，半约束期内旋转离心力和身管组半锥夹角导致的科氏力对弹丸起始扰动有影响，同时弹丸偏角将随着身管转速的增加而线性增加，特别是高射速时，弹丸的偏角更大，这些可为转管武器的射击精度研究提供参考。

The effects of gap size, shape, inclination angle, pressure and form losses of two ends of annuli were discussed. Based on experimental data and theoretical analysis results, a new half-empirical correlation was also derived which can accurately predict the CHF of vertical annuli, circle tube and rectangular channel in a very wide range of H/De values.

在实验和理论分析的基础上，提出了一个新的，可用于计算竖直环隙、圆管及长方形流道内自然对流沸腾临界热负荷的半经验公式，其计算精度和适用范围较现有的计算公式有显著提高，原则上不受H/De值大小的限制。
