最后推导出模具最佳半楔角公式。

By using a coherent state method,we prove that the geometric phase of the spinor in rotating magnetic fields to be one half of the solid angle that the spinor states sweep.

运用相干态方法，本文证明了中子在旋转磁场中的几何相位是粒子态矢量在态空间中扫过的立体角的一半，同时提供了一种几何相位在周期演化中的简单算法。

The Flat-to-Down rail is alot like the flat rail except for the change in angle half way through the rail.

这个东东和完全笔直的rail的不同之处在于，它在中途是有个角度的，所以英文中叫flat-to-downrail，很形象是不是。

Parabolic crafts with various geometry parameters are analyzed on this method. The calculated results show that the half open angle of craft affects the coupling coefficient of momentum.

计算结果显示飞行器获得的冲量耦合系数和飞行器的半张角有关，半张角相同的飞行器，焦距大的冲量耦合系数要大。

One exception to the rule does exist and it is an important one, a well-laid back upper arm (remember the other half of the 90-degree angle) can partially compensate for a steeper shoulder.

但也有一个例外，这个例外至关重要：一个充分靠后的前臂（90度成角形成的另一半组成部分）能够在一定程度上弥补肩部不平的缺陷。

It is fou nd that in two dimensional case the wave-packet propagates downstream in the we dge-shape,the angle of the half wedge is 10° which is in good consistence with the experiment data.

发现点源波包在二维边界层中呈楔形向下游传播，其横向偏角为10°，与相关的试验图片相吻合。

Resolution of the secondary electron image ; equifinal spherical aberra tion coefficient ; optimum half open angle ; limit resolution

二次电子像的分辨本领；等效球像差系数；最佳半开角；极限分辨本领

Based on point explosion theory , the approximate analytical formulas of momentum coupling coefficient and impulse of cone and parabolic crafts are deduced. The results show that the total axial impact momentum for parabolic craft is larger than that of cone craft and it increases with the increase of half open angle.

以LSD/LSC波理论为基础建立了一个近似的理论解析模型，推导出圆锥形和抛物形飞行器获得的冲量及冲量耦合系数的近似解析表达式，公式表明冲量耦合系数随着半张角的增加而增加，同时抛物形飞行器要比圆锥形飞行器的动量汇聚效果好。

Computer simulations reveal that among the 20:1 ultra-wide frequency range VSWR is small, antenna pattern doesn't split and the lognitudinal length is less than half of the traditional small angle LPDA.

计算机模拟结果表明：该天线在20：1的超宽频带内驻波比小、方向图不分裂，纵向长度比传统方法设计的LPDA缩短一半以上。
