对称

The introduction of local supersymmetry on worldsheet results in the Ramond-Neveu-Schwarz model, and global supersymmetry in the ten-dimensional spacetime directly yields the Green-Schwarz superstring.

这两种描述方式的不同点是：Ramond-Neveu-Schwarz超弦理论在超弦的世界面引入局域的超对称，Green-Schwarz超弦理论是在十维时空中直接引入超对称，它是一个协变的理论。

In this paper one loop SUSY QCD radiative correction to gb→tH - cross section is calculated in the context of Minimal Supersymmetric Standard Model.

在最小超对称标准模型的框架内计算了gb→tH-过程产生截面的单圈超对称QCD 修正。

We find that the RPV effects on some observations could be large, these results could be useful for probing the RPV SUSY effects and will correlate strongly with searches for direct RPV signals at LHC.

这些研究结果对于探测R宇称破缺超对称是非常有用的，它们与在LHC上寻找直接的R宇称破缺超对称信号有很强的关联。

The results show that most flows with zero pressure difference are symmetric, but tiny pressure difference will make the flows between upper and lower channel asymmetric.

其结果发现，当出口处无压差时，流场大部分呈现对称的状态；而当有压力差时，则会造成上下方流道内的流场，出现不对称的现象。

An algorithm for extracting features with symmetric figure, such as buildings and so on, from binary image, as well as a measurement of image matching.

4，地形图二值图象中具有对称形状要素的提取方法，以及一种图象匹配的量度，实现了地形图中具有对称形状要素的建筑物、构筑物的提取。

This theorem states that the sum of the symmetric logic variables constitutes a level-0 kernel of the symmetric logic function.

该定理表明，对称逻辑函数的对称逻辑变量之和恰好构成了该逻辑函数的一个零级核。

And each symmetric function can be written into a linear combination of homogeneous symmetric functions.

这样，就可以把一个n元对称布尔函数转化为一个n+1维向量v_f =v_f (0， v_f (1)，…， v_f，其中v_f表示重量为i的函数值， 0≤i≤n，此向量v_f称为对称函数f的向量值，极大地减少了对存储空间的需求，并且在软件应用中发挥着重要作用。

Based on the previous work, two expansion formulas of fully symmetric wave function for describing three bosons in different orbits are obtained, which can be used to calculate the nuclear specturm.
