The results show that the films are characterized by the amorphous microstructure and mainly composed of Si C bondings, C C bondings as well as a small mount of oxide impurity consorted with Si; the content of the C C bondings decreased after annealing in vacuum, meanwhile the Si C bondings content increased, annealing in vacuum is beneficial to the formation of SiC; after annealing at 800 in air, a thin dense layer of SiO2 formed on the surface, which prevented the oxygen from contacting with the film and effectively protected the inner SiC from oxidizing.

结果表明，薄膜主要以非晶为主，由Si--C键， C--C键和少量Si的氧化物杂质组成；在真空条件下经高温退火后，薄膜C--C键的含量减少，而Si--C键的含量增加，真空退火有利于SiC的形成；在800℃空气中退火后，薄膜表面生成一层致密的SiO2薄层，阻止了氧气与薄膜内部深层的接触，有效保护了内部的SiC。

This gaseous impurity is able to bring about metal corrosion and contaminating.

这些气相杂质的存在会造成金属材料腐蚀，并污染环境。

Crewed Crude oil or unprocessed petroleum is called * sour, when it contains a lot of * sulfur, an impurity.

Extracted DNA by CTAB, in proportion to the additions of PVP and β-mercap toethanol to the extraction buffer were capable of preventing browning from taking place in the extraction, Tris-Phenol (Stabilized with 0.1M Tris, pH 8.0)/Chloroform/isoamyl alcohol were used to remove protein and impurity in the second extraction, during crude DNA used to Isopropanol DNA and deterged by DNA detergent, without using RNase remove RNA, we detected the quality and concentration of DNA respectively for normal leaves and drought stress leaves by Agarose gel electrophoresis of genomic DNA and ultraviolet spectrometry photo.

用20%聚乙二醇(polyethylene glycol，PEG6000)模拟干旱，采取CTAB提取缓冲液，按一定比例加入PVP和β-巯基乙醇，用Tris平衡酚－氯仿－异戊醇除去蛋白质及杂质，在粗提时用异丙醇沉淀DNA，并用DNA洗液（10mmol/L醋酸铵，75%乙醇）洗涤DNA，在纯化时用乙醇沉淀DNA，且没有加入RNase去除RNA的方法，分别提取2个品种正常和干旱胁迫的苹果属叶片总DNA，并对提取的DNA进行琼脂糖凝胶电泳和紫外分光光度计检测。

Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves

所以，神任凭他们逞著心里的情欲行污秽的事，以致彼此玷辱自己的身体。
