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。

With the change of the interval, analog output channel outputs variant voltage to frequency converter that controls the speed of the motor.

根据载荷设定值的大小，系统根据等比关系将其模糊化成几个区间，并确定当前采集到的载荷的区间号，根据区间的变化赋予采集卡的模拟输出通道一定电压输出到变频器，最终控制电动机的转速，使整个加载过程保持平稳。

The energy-orthogonal character of Wilson element,Q_1 element,rotated Q_2 element,Bergan 9-parameter triangular element[6],5- parameter[23] and 8-parameter rectangular element[20] is analysed in this paper.

The results indicated that the high level density functional theory calculations can be used to predict the 13C chemical shifts of the modified nanotubes. The calculated results also provided the characteristic chemical shifts values of nitrene (superscript -), carbene (superscript -) and 1,2- and 1, 4-fluorinated nanotubes, which would be helpful for experimental spectrogram assignments. Combined with NMR experiments, these predicted characteristic chemical shifts can be further used to monitor the addition mechanism and the extent of surface modifications on nanotubes.

研究表明高精度的密度泛函理论计算能够用来预测纳米管的13C化学位移，理论研究的结果揭示了氮烯、卡宾以及1，2和1，4氟化的单壁纳米管的若干13C信号特征化学位移值，为实验NMR谱图的归属提供了一定的依据，并且可通过与实验相结合来监测表面官能化碳纳米管加成反应是否发生以及确认其加成方式。

The resulting tuple stream contains one tuple for each combination of values in the Cartesian product of the input sequences.

结果元组流对每一个值与输入序列的笛卡儿乘积的组合包含一个元组。

Relatively speaking, the use of chroma GMI to implement quantitative business card printing and membership card making to advance a great step forward.

相比而言，GMI在利用色度值来实现量化制卡和会员卡制作方面以超前了很大的一步。

Mercator is the type of projection you see used on Live maps and Google maps, but as many often mistakenly thinks, they do NOT use WGS84 for the projected map, although WGS84 is used when you directly input longitude/latitude values using their API.

Live Map和Google Map都使用墨卡托投影，但并不像人们认为的那样他们使用WGS84基准面，虽然你在他们的API中输入的值是WGS84下的值。【译注：原因是WGS84基准面是基于椭球面的，而LiveMap和GoogleMap使用的是球面。另外，YahooMap使用的是等距圆柱投影。

General Washington saw once again that there was no hope for the United States under the Articles of Confederation.

美国虽然有了美元，但，一美元在各个地方的价值却不一样，在纽约，一美元值8先令，而在南卡罗莱纳，一美元却值32先令。

Firstly some viewpoints are not accurate, for example "convention T is the definition of true sentence","truth-conditional theory is truth-coincidence theory". Secondly no one takes note of the relationship between Tarski's truth-conditional semantics and Carnap's intentional semantics.

但这方面的研究就目前来看，至少还存在两个方面的问题：第一，有些提法是不准确的，如&T约定即真句子的定义&，&塔尔斯基的真值条件论是真理符合论&；第二，忽视塔尔斯基的真值条件语义学与卡尔纳普的内涵语义学间的联系。
