Though the UMP survey is only three-quarters complete, evidence is compelling that the universe is not saddle-shaped, as Einstein thought, nor spherical as many before him believed.

虽然宇宙图谱计划测量仅完成了四分之三，但证据表明宇宙不是如爱因斯坦所认为的那样是马鞍状，也不是在他之前许多人深信的球状。

Thus, the spherical-crown and saddle-shaped surfaces were demonstrated. Consequently, the basic rules and key technology of bending forming using plasma arc in practical work were obtained and the application level of the flexible forming using plasma arc had been further improved. The effects of the main parameters including power, scanning speed, scanning distance and scanning sequence had been investigated.

对成形中出现的棱角效应进行了机理分析和数值计算，结果表明棱角效应是板材沿扫描线方向受几何约束产生了较小的压应变及在扫描线上、下表面的收缩量不同所造成；提出了通过分段扫描解决棱角效应的方法，明显提高了成形质量。

The experimetal results show that the flexural moment of the sample in the prebending direction is far bigger than that in the vertical direction to pre-bending and the spherical shape can be conquered during pre-loading laser peening forming to a great extent.

试验结果表明，在弹性预加载下，板料在弹性预弯方向获得的弯矩要比与弹性预弯垂直方向上的弯矩大得多，弹性预加载下激光喷丸成形可以有效地克服自由状态下激光喷丸件呈球形现象，激光喷丸件的曲率是自由状态下激光喷丸成形曲率的2～3倍；在相同曲率下，弹性预加载下激光喷丸成形件的表面粗糙度比自由状态下激光喷丸成形件的表面粗糙度要低1～2等级，因此弹性预加载下激光喷丸成形要优于自由状态下的激光喷丸成形。

The numerical results show that the laser DSS of the moving spherical particle is tightly connected with its speed and scattering zenith angle.

结果表明：运动介质球粒子的激光雷达微分散射截面与粒子的速度和散射天顶角有关，当粒子做低速运动时，由于运动对粒子的激光散射产生的影响可以忽略。

Based on Mie theory, the scattering figure and extinction curve of spherical particles with different sizes are presented.

从Mie理论出发，得到了不同尺度的球形粒子对激光的散射图像及粒子的消光效率曲线。

The DSS of a moving spherical particle is explained by the electric and magnetic field from Mie scattering theory.

首次利用Mie理论，详细的研究了高速运动介质球的散射特性，得到了运动介质球粒子散射截面的解析表达式。

Double star tests, while interesting to mention in reviews, are not quite as useful for judging the contrast and quality of optics, since things like secondary obstruction and residual spherical aberration often don't impact the view of double stars as much as they do high power planetary detail.

但是请记住，训练有素、挑剔的眼睛，通过星点测试，可以发现一些光学上的暇癖，但是这些小问题对最终成像几乎没有影响，因此你大可不必那么挑剔。

Furthermore, the equation of surface reflection seismogram generated by spherical wave pro.

利用弹性动力学方程变换和递归算法，计算了反射矩阵，从理论上推导了球面波在层状弹性半空间传播时产生的地面反射记录的计算公式。

The spherical center of the self-aligning seat must coincide with that of the self-aligning ball bearing.

球面中心的自我调整的席位必须配合，在自调心球轴承。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
