用原子力显微镜对热铁盘法抛光CVD金刚石达到R0.016μm的表面进行观察。

A: I am Ra. We cannot work with this concept as it is misapplied and understanding cannot come from it.

A ：我是拉。我们无法用这个概念来工作，因为它被误用，进而无法产生理解。

This paper introduces a convenient reengineering assistanttool which was developed by the author and other researchers in De Montfort University,UK,and can be used to abstract a specification from a pro-gram(i.e.from source code text to specification source text),and give a case study with RA.

因为程序设计和规约是在更高的抽象层次上，这一层次更简洁或易于理解。从源代码中成功抽取面向语义的规约，将有利于理解，从而有助于对遗留系统进行再工程。从

A: I am Ra. We will answer more specifically than the question.

A ：我是拉。我们的回答将比你的问题更明确。

It may play an important role in the pathogenesis of myopia.

Using the changing rate of maximum feed-rate as a threshold,the surface of the part is divided into different areas according to the values of normal curvature radius.Then the feed-rate is adjusted by constant velocities of cutter contact,thus the adaptive variation of feed-rate can be reached.An example is given to prove the ra...

以最大工作进给速度的变化比率为阈值，把零件表面的法曲率半径划分为不同的区域；在不同的曲率区域内，分别以恒定的刀触点速度对进给速度进行修正，修正后的进给速度随着零件表面曲率的变化而自适应变化；实例表明该方法具有合理性和有效性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。
