Eight-shaped double-disk sub-grass ditching device installed in the two pre-installed as "eight-shaped" arrangement of the concave disc of crushed corn stalks after the strong role of the sub-grass.

八字形双圆盘分草装置在开沟器前安装两个成&八字形&布置的凹面圆盘，对粉碎后的玉米秸秆有很强的分草排堵作用。

Occult rings supposedly had magical powers; and poison rings had hollow bezels that could be filled with poison for the purpose of suicide or homicide.

Solid desiccants Solid desiccants are characterized by an internal porous structure that contains very large internal surface areas with very small radii of curvature. The equilibrium partial pressure of water vapour above such concave surfaces is much less than that above plane surfaces and so solid desiccants exhibit a very great affinity for water.

坚实干燥剂坚实干燥剂为包含非常大内部表面以非常小半径曲度的一个内部多孔结构描绘。water.vapour 平衡部份压力在这样凹面表面之上是较少比那在平面表面之上和因此坚实干燥剂陈列非常巨大亲合力为水。

水罐可以分为很多种，一种是有碟口、宽颈、宽身、凹面罐底，扁平的手柄，六边形较短的喷口。

The results show that the maximal rolling pressure and the maximal strain in rolling process don't appear in the same location; the plastic strain areas locates on the both sides of the edge at the fillet, resulting in residual compressive stress reached to strengthen the purpose of rolling.In the rolling process, must be reasonable to control the feed roll.

结果表明，滚压过程中最大滚压力和最大应变不是出现在同一位置，塑性应变区域位于圆角凹面两侧边缘，冷作硬化后产生的残余压缩应力达到了滚压强化目的；滚压过程必须合理控制滚压进给量。
