All hallows eve has been traditionally seen as the one night of the year when the veil ( yes , the veil ) that separates the worlds of the living and the dead is at its most thin and penetrable 万圣节前夜被传统地认为是分开生与死两个世界的帷幔在一年当中最微薄的一个晚上。

The results showed the following : the siphon drainage effect of hank slope is not markedly obvious with more penetrable rock soil , hut is obvious for soil with less penetrability 结果表明：对于渗透性较大的岩土体，岸坡虹吸排水效果不明显，而对于渗透性较小的岩土体，岸坡虹吸排水效果明显。

Integrating the power flow program with the tools matlab simulates the transient response of the distribution networks with the direct combination wind generator under disturbances , it provides the credible rationale to the research on stability and maximal penetrable power 本文结合配电网潮流程序，利用matlab作为仿真工具，模拟包含直接并网风能转换系统的配电网络在受到扰动情况下的暂态响应，对含有风电场的电力系统稳定性研究及风电场极限穿透功率的研究，提供了可靠的理论根据，有重要的现实意义。
