原文：Abstract The study proposes a non-contact adjustment method of grinding wheel alignment in ultra-precision grinder by using electric capacitance between a grinding wheel and a reference ball. Cemented carbide with almost no binder is used for die material as molding glass lens. The carbide is one of the most difficult-to-cut materials because of its high hardness. Diamond wheel therefore is generally used for grinding the material under quite light grinding conditions such as less than 1 micrometer of depth of cut. In such ultra-precision grinding, an alignment and a radius of a grinding wheel must be settled precisely to achieve high efficient grinding. In ultra-precision grinding, grinding and measuring are repeated several times, that is, after grinding the work form is measured, and the result is used to correct a grinding program for next grinding. The method proposed in this study is based on an electric capacitance between grinding wheel having conductivity and the reference ball, this means that the method is carried out without any contact between the wheel and the reference. The capacitance is in inverse proportion to the gap, and that can be measured precisely. Using the method, the alignment and the radius of the wheel can be adjusted within short time.- X8 A& X0 c4 L
译文：（第一句怎么翻译也不对 ）几乎没有硬质合金的粘结剂被用于玻璃镜片的成型模具材料。由于碳化物是一种高硬度的材料，所以其最难切割。因此，金刚石砂轮磨削一般用于磨削深度较小的情况，如小于1微米的切削深度的物质。在这种超精密磨削中，为了实现高效率的研磨，磨床砂轮校直和转角半径必须解决。在超精密磨削，磨削和测量重复几次，即磨后测量的工作方式，结果是用来纠正下磨削磨削方案。该方法在本研究中是通过一间电容量的磨削砂轮具有导电性和参考球，这意味着，该方法无需进行车轮之间的任何接触和参考了。电容是成反比的差距，并能精确地测量。使用该方法，路线和车轮的半径，可在短时间内调整。 |

不过，你翻译得确实不错。
