偶置换

The odd L yrast states can be either symmetric or antisymmetric, while the even L ones are only symmetric under the permutation of the two components.

我们证明了，对于奇角动量和偶角动量，yrast态有不同的行为，即在两分量间的置换下，奇角动量态可以是对称的，也可以是反对称的，而偶角动量态仅存在对此解。

Second, to eliminate a special class of cycles in QC-LDPC codes, we considerQC-LDPC codes with circulant permutation matrices as protograph LDPC codes. Andwe reveal the relationship of cycles in a protograph LDPC code and its mother matrix.

其次，为了消除准循环低密度奇偶校验码中一类特殊的环，我们把由循环置换矩阵扩张得到的准循环低密度奇偶校验码看做一类原图低密度奇偶校验码。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
