Starting from the lighter Mg atom, the both cases in which the autoionizing states are excited from the spherically symmetric and non-spherically symmetric Rydberg targets were investigated with different physical models.

从较轻的Mg原子入手，分别针对球对称靶的和轴对称靶这两种情况，采取不同的物理模型对其自电离弹射电子的能量分布进行了深入的理论研究。

In this paper, the principle and construction of a automatic lathe which is used to turn ball of oil sprayer are introduced.

文章介绍了一种车削喷油器球头自动上下料机构的原理及结构。

The Nothoperanema Ching is a small genus of Dryopteriaceae s.l.,it have 5 species now,the squama,the shape and texture of leaves,and many extermal forms are close to the Peranemaceae,the two may have close relationships.

肉刺蕨属NothoperanemaChing是鳞毛蕨科的一个小属，现有5种，该属在鳞片、叶形、叶的质地等外部形态方面与球盖蕨科很相似，二者之间似乎存在密切的亲缘关系。

But it is stasis that does an Ecosphere in.

不过，一个生态球的真正状态，还是一种沉静。

According to different purposes, NH Kneader can be made of vacuum, pressure, atmospheric pressure three; temperature tune the form of the use of jacket, steam, conducting oil heating, water cooling, etc.; material means there is hydraulic, double-cylinder for dumping, Ball material, such as screw extruder.

根据不同的使用目的，NH捏合机可制成真空、压力、常压三种；温调形式采用夹套，蒸汽、导热油加热，水冷却等方法；出料方式有液压、翻缸倾倒、球阀出料、螺杆挤压等。

A grating function and a groove function are introduced to determine the structure of a concave grating. Basic ideas for the design of a flat-field concave grating with three stigmatic points are proposed. As a proof of the usefulness of these design approaches, image conditions of the grating with three stigmatic points are developed which concise with other published results and they are more general than those obtained from holographic gratings.

采用与分析三维光栅相类似的级数展开法给出了二维集成凹面光栅的球差、彗差的计算方法，计算中用光栅函数和槽面函数来描述具有任意形状和任意变化周期的光栅，提出了一种具有三个无像差点的平面场型凹面光栅的设计方法，利用该方法推导了三点无像差光栅的成像条件，与文献中用其它方法获得的结果相一致，该结果与全息光栅的成像条件相比，更具一般性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
