secondary property

By using the property of the secondary quasi diagonal matrix's index, a computational method of the Drazin inverse of even order anti centrosymmetric matrices is given. [ WT5HZ]

利用次准对角阵指标的性质，给出了偶数阶反中心对称矩阵Drazin逆的一种计算方法。

The secondary fissure, located on the upfaulted block of the major fissure, has the normal fault property with north dip and north downthrown, and merges into the major fissure with Y-shaped distribution at depth 300-500m in Quaternary system.

次缝位于主缝上盘，具有北倾北降的正断裂性质，并与主缝断裂呈丫字型构造，在深度300～500m处的第四系内与主缝汇合。

The conclusions were showed as following: 1. Aluminum electrode showed relatively good property in the cycles as negative material of lithium-ion secondary batteries. Its capacity reached 400mAh/ g, which is higher than the theoretical capacity of carbon.

采用Al极片作为锂离子二次电池的负极材料在循环中表现出较好的综合性能，容量可到达400mAh/g，高于石墨理论容量。

Indirect infringement of intellectual property has three forms: aiding infringement, secondary infringement and infringement by subrogation.
