Since the production of carbon nanotubes synthesized by arc-discharge method contains impurities such as carbon nano-particles, amorphism carbon and graphite fragment, several purification methods were used to purify carbon nanotubes. It is found that with oxidation method in air, we can easily get purified carbon nanotubes.

由于用电弧放电法合成出来的纳米碳管产物中除了有纳米碳管外，还含有一些纳米石墨颗粒、无定形碳和石墨碎片等，因此本文对用电弧放电法合成出的纳米碳管进行了多种方法、探索性的提纯研究，实验结果发现，利用大气氧化法对纳米碳管进行提纯效果好，设备简单，是一种方便实用的方法。

The refractive indices of Nd:GGG were measured by the absorption spectrum method and autocollimation method.

用吸收光谱法和自准直法测量了Nd：GGG的折射率，二者给出的折射率测量结果符合得很好，表明用晶体透射光谱来测量折射率是一种有效的简易测量方法。

I found a couple of years ago can make insoles and durable material, so he used to make insoles, non-tight and durable, but also good to wear, to now also do not change, it is dedicated by the multi-layer fiber woven and synthetic rubber compounds made, divided into 3 layers, surface layer is the fiber fabric, middle layer and the bottom is rubber with heat and chemical energy in the precise combination of control, and fiber fabrics on each floor are different woven layers of synthetic fiber and natural fiber group into, the durability of the market than any of the insoles to be durable.

我早两年发现一种耐用可以做鞋垫的材料，于是就用来做鞋垫，不紧耐用，还很好穿，到现在还不用换，它是由多层专用纤织和合成橡胶化合物制成，分为3层，面层是纤织品，中间层和底层是橡胶用热能和化学能在精确控制中结合在一起的，纤织品每层都不同，纤织层是合成和天然纤维组成，耐用性比任何市面上的鞋垫都要耐用。
