Left right symmetry
对称───symmetric;左右───about
Physical laws, too, can be symmetric.───物理定律也可以是对称的。
It's perfectly symmetric.───它是完全对称的。
Moreover, when A is a nondegenerate, symmetric and copositive plus matrix, the sequence converges to a solution of the problem.───此外，当矩阵为非退化对称双正加阵时，该序列收敛。
The optimum intersection angles and the point position of symmetric resection are deduced by means of analytic method.───用解析法导出对称交会时最佳交会角和最佳点精度；
When a law remains unchanged regardless of the situation, it, like the circle, is said to be continuously symmetric.───当定律不随（时空）条件（Situation）而改变的时候，比如圆形，它就被称为具有连续对称性（ContinuouslySymmetric）。
A poset is called a symmetric chain decomposition if the poset can be expressed as a disjoint union of symmetric chains.───如果一个偏序集可以分解成不相交的对称链之并，则称此偏序集具有对称链分解。
