The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.

结果表明：腹鳞表面的微观结构由指状微突体和板结构部分周期排列而成，其结构可用9个特征参数定量描述；腹鳞表面摩擦力由分子作用力、表面微突体的犁沟力、楔形作用力以及材料弹性滞后共同引起；腹鳞表面的摩擦系数在0.07左右并与运动方向有关，摩擦系数随载荷增加而减小；后向运动及左、右侧向运动时摩擦系数基本相等，比前向运动时高33%左右；腹鳞表面微突体不同方向上倾斜角度的差异是引起摩擦各向异性的主要原因。

在分析罗拉斜齿顶面棕刚玉砂轮磨削缺陷的基础上，提出用立方氮化硼砂轮代替传统的棕刚玉砂轮进行磨削加工；确定CBN砂轮的构造特性和结构尺寸；设计CBN砂轮金刚滚轮修整装置；并对CBN砂轮修整参数进行深入分析研究。

Although tooth enamel is a very hard tissue, it is very vulnerable to acid.

虽然牙釉质是一种非常硬组织，很容易受酸。

The thing to watch out for is that the treatment that you use does not do any damage to your tooth enamel.

需要注意的事情是，为您使用的治疗没有做任何损害你的牙齿珐琅质。

Once tooth enamel is lost, it's gone forever.
