Considered from the data security Angle, this system establishes log-in boundaryplane for each sale to realize the identification.
从数据安全角度考虑，本系统对各个销售点都设置了登录界面以实现身份验证。

The perfectly matched layer (PML) boundary condition is used to effectively absorb out going wave on the boundaryplane by comparison with the absorbing performance of dispersive boundary condition.
采用理想匹配层边界条件以有效吸收边界面上的出射波，并与色散边界条件的吸收效果作比较。

The paper evaluates the limitations that semielliptical surface crack in a shaft is simplified to a unilateral crack in a finite boundaryplane and a cross straight line crack in a semi infinite body.
