It now enchants a piece of chest armor so it has a chance per hit of giving you physical damage absorption.

现在腐蚀剂一块胸部盔甲，它有机会，每击中让您身体损害吸收。

Face has its positive value when properly guided and regularized, otherwise it may turn into a kind of corrodent for the souls of people.

其礼义廉耻、自尊、个性、权利等成分若加以正确规范引导有其积极意义与价值；若表面化视为一种虚荣的名誉身份地位表现则易转为无形无味腐蚀剂。中国人最讲也最爱面子，是人情大如天、人际与人生哲学的发祥地和信奉者。

Power is the great corrupter of politics, business – and marriage.

The choice of escharotic is decided by stone chemical component.

石材的化学成分决定了选择腐蚀剂的种类。

And there 3 kind of mineral the character exist great difference, their reaction to the escharotic are also quite different.

而这三种矿物的性质相差很大，对腐蚀剂的敏感程度也大不相同。

Different escharotic decide the different speed of reaction, thus to cause the great effect on stone carving speed, carving effect, for example, marble whose mainly component is carbonate, so it is better to choose escharotic made from HCI, while for granite , whose mainly component is silicate, it is better to choose escharotic made from HF

腐蚀剂类型的不同又决定了反应速度的差异，进而对雕刻速度、雕刻效果都会生产比较大的影响，例如，以碳酸盐为主要成分的大理石类石材，选择由HCl配制的腐蚀剂比较适宜；而以硅酸盐为主要成分的花岗石类石材，选择由HF配制的腐蚀剂比较适宜。

The morphologies of the CdZnTe etch pits developed by four etchants including Nakagawa, Everson, EAg1 and EAg2 solutions are studied. The results show that the etch pits of EAg2 etchant on the (111) B surface are flat-bottomed. And the etch pits of Everson etchant on (111) B include flat-bottomed pits and pyramidal pits with different slant directions, while the positions of pyramidal pits don′t move as the surface layer is continuously removed.

对碲锌镉晶体常用的Nakagawa、Everson、EAg1和EAg2四种腐蚀剂在碲锌镉材料（111）晶面上的腐蚀坑坑形进行了研究，结果发现，EAg2腐蚀剂在（111）B面上的腐蚀坑为平底坑，Everson腐蚀剂在(111)B面上产生的腐蚀坑包括平底坑和带有不同倾斜方向坑底的三角锥形坑，进一步的研究还表明，三角锥形坑并未沿着坑底的倾斜方向向下延伸。
