Since is the life in aquatic, also lets us be suitable the water cause natural subcrust current to get down. 既然是生活在水上，且让我们顺着水的因缘自然地流下去。
In this paper, erosion behaviors of high manganese steel under high velocity impacting of alundum particles (200m/s) have been investigated by erosion surface morphology,debris morphology and hardness of subcrust analysis. 本文通过对高锰钢的磨损表面形貌、磨屑形貌和次表层硬度的分析等手段研究了高速氧化铝粒子(200m/s)冲蚀下高锰钢的磨损特性。

Some statistics revealed that in the first half of this year, in the national land market has more than 40 subcrust current rackets, the massive lands only finalized a deal by the base price. 有统计显示，今年上半年，全国土地市场上有40多块地流拍，大量土地仅以底价成交。
On the other hand, once by mainstream Fang Qichao in the fiery land market, already was disappeared once struggled captures king's main forces, the earth subcrust current sign frequency is present. 另一方面，曾经被主流房企炒得火热的土地市场上，已经不见了曾经争相夺取地王的主力们，土地流标频现。
