MGM is introduced to solve field distributions in 3-D electron optical systems. The difference equation, the discrete form of Laplace's equation, is deduced in 3-D Cartesian coordinates. In view of the smooth effect, MGM combines Gauss-Seidel iteration with a technique known as coarse grid correction. Formulae for restriction and prolongation are deduced and expressed in terms of tensors.

将多重网格法引入电子光学系统中三维静电场的计算，对三维笛卡尔坐标系中的差分方程，采用高斯-赛德尔迭代法求解差分方程组，并结合迭代过程讨论了粗网格的误差校正技术；在不同网格层之间进行场值的限制和延拓，推导了三维静电场中的限制、延拓公式并以张量的形式表示。

利用国家天文台微波(1.0—2.0GHz和2.6—3.8GHz)射电频谱仪于1998年9月23日观测到了一个稀少事件，它是一个伴生多重周期脉动、Ⅲ型爆发和类Ⅰ型噪暴的复杂射电Ⅳ型爆发，着重介绍该爆发所具有的多重长周期(约7.3、4.9、3.7、1.2和0.4分钟)脉动成分。

The entropy is a very important core concept in the information system, By calculating and comparing the entropy in the multiple-choice question, this paper analyzed the significance of the multiple-choice question s entropy in Drill and Practice courseware.

信息熵是信息系统中一个十分重要的核心概念，本文通过对课件中多重选择问题的信息熵的计算比较，浅析了多重选择问题的信息熵在操练与练习型结构课件中所体现的意义。

Cosmos is the unique cosmos , and i am the unique i , but the symbolized and conceptualised cosmos and i are multi - structured and multi - layered , so they supply a flexible space for individual in specific context

作为存在本身，宇宙是唯一的宇宙，我是唯一的我，而认知框架是多重的，且在同一框架下也存在多重认知平台，孰轻孰重取决于具体时空场景。

QL have the same height as the chain after it connected, so the surface will be smooth. Beside, the heights of chutes are the same, the interval become smaller. The safety is higher than before. Moreover, we add the special tenons on the up and down each side, which can make the QL safer. Those special skills ensure the safety and won't be slipped under the normality.

QL 安全扣在组装后与链条为同等高度，故其小轴不会有凸出的问题，且因全部滑移面高度相同，故其间隙会变小，增加其安全性；另在 QL 安全扣的小径部两侧增设多重的卡掣块，形成多重保护，在正常使用的状态下无脱落的可能性，确保其使用上的安全性。

But when a rectangular continuous data set appears to have a longer tailed than normal distribution or it contains some values that are influential on statistical inference with normal distribution, the multivariate t distribution becomes useful for multiple imputations as an alternative to the multivariate normal distribution.

在多重插补法的基础上，当一个矩形连续数据集看起来有一个比正态分布还长的尾巴，或者是它包含了一些对正态分布的统计推断有影响的数据，多元t分布作为多元正态分布的替代分布，对于多重插补来说变的很有用了。
