How to avoid aberration of grid shapes in the air gap region when rotor rotates, however, is the trickiness problem for the finite element method.

As the multi-part of magnetic pole have been adopted, the deflection center is easy to adjust and every order of the Trilemma constant can be made zero or small in each region, so as to correct the deflection aberration by multipole field.

He expressions of the various order of Trilemma constant are given, in which the seventh-order Trilemma constant can be used as a criteria of the deflection aberration correction at large deflection angle The high resolution display tubes with large deflection angle makes more demands on deflection sensitivity.

rilemma效应是偏转系统实现自会聚的一个重要判据，对高级偏转像差的校正，需要考虑高阶Trilemma效应的影响，本文从多极场偏转像差校正理论出发，应用区域分割的方法，对直至七阶的Trilemma效应进行了分析，给出了各阶Trilemma常数的表达式，其中七阶Trilemma常数可以作为大偏转角偏转像差校正的判据。

Compare, for example, the optical designs of the 17th century physicists Descartes and Huygens shown below, with those of two trilobite species. The result is that, even without the benefit of accomodation, the rigid trilobite doublet lens had remarkable depth of field (that is, allowed for objects both near and far to remain in relatively good focus) and minimal spherical aberration.

相比较而言，有一个很好的例子，在17世纪，物理学家迪卡尔和惠更斯同样展示了这种视觉构造，这刚性的三叶虫的眼睛，有着不寻常的景深（在观察近的以及远的物体能同样的聚焦），另外它还具有最小的球状像畸。

The derivation has stronger anti-phlogiston algesia effect, which can be used in rheumatic arthritis and mental aberration.

该衍生物具有较强的抗炎镇痛作用，可用于制备治疗风湿性关节炎及心率失常方面的药物。

His boldness lies in realizing that he could eliminate the spherical aberration by placing a thin, very weakly curved lens ("correction plate") of special smooth shape (convex near its middle, concave near its periphery, and flat in between) at the same location as the apertured diaphragm.

他的勇气，就在于实现，他可以消除球面像差放置一个薄，非常弱弯曲镜头的特别顺利形状（凸近其中，凹附近及其周边地区，并在单位之间的）在同位置作为光阑膈肌。

The L band 500W SSPA module which has reached national level is the first sample of the Southwest China Research Institute of Electronic Equipment in this aspect;2. The method which to obtain fast rising time for narrow pulse width is got;3. The method of eliminating autoecious surge with pulse power amplifier is presented;The cause of pulse shape aberration is analysed.
