The oil sewage disposed process is a complex disposal technique. The disposal process is more difficult for the change of PH Flux temperature of raw water and the other polluted quality. At present the disposed water by the system of oil of sewage is unstable and high cost. Now the method for the oil of sewage have physics chemistry physical chemistry and biology etc. In the every disposed method has its own specially, Basis of the oil sewage condition of power plant. The text use chemic method. Another word is method of Flocculation-deposition. Injecting Dosage into sewage. Making small suspends grain and the electrophorus colloid gather into bigger colloid and deposit. Separated it from water and purify the oil sewage. Make disposed oil water up to grade.

含油污水处理工艺是一个复杂的处理过程，在处理过程中由于受到原水浊度、PH值、配水流量、原水温度和其他水质污染等因素的影响，处理难度相当大，现时的含油污水处理系统普遍存在处理后的水质不稳定和处理成本高等问题，国内外含油污水处理采用的方法有物理法、化学法、物理化学法和生物法等，每种处理方法都有自己的特点，结合电厂含油污水的情况，本文主要采用化学法，具体来说是采用絮凝沉淀的方法，通过向废水中投加混凝剂，使细小的悬浮颗粒和带电胶体微粒聚集成较大颗粒而沉淀，使其与水分离，使含油污水得到净化，使处理后的废水各项指标达到排放标准。

The result is showed that the Gq α were specifically localized in the rhabdoms as the membrane-bound form and in the cytoplasm as the soluble form. The localization of Gq α changed depending on the light condition. In the dark, many immunogold particles were detected in the rhabdom rather than in the cytoplasm.

在暗适应后，Gqα主要分布于感杆束，细胞质中很少，感杆束与细胞质中胶体金颗粒的密度比为2.11±0.186；在光适应后，密度比减少为0.63±0.056；在不同波长的光照处理后，Gqα定位有差异，感杆束与细胞质中胶体金颗粒的密度比由高至低，依次为：绿光（2.38±0.179）、红光（1.99±0.177）、蓝光（1.92±0.163）和黄光（1.02±0.106）。

Compared with that of 3Cr13 alloy, the oxidation resistance of the composites containing 5 vol.％TiC particle was improved greatly at 850℃, but the improvement was relatively limited at 950℃. But the oxidation resistance of 1Cr18Ni9 composites containing 5 vol.％ TiC particle was obviously improved at 950℃, and at 850℃ the improvement is not large. The TiC particle can improve the oxidation resistance mainly was by developing the oxidation selectiveness of the Cr element as to change the phase constitution of the oxidation film, to alleviate the production of the stress in the oxidation film and to improve the cohesive force of the oxidation film or matrix interface and the chemical combination of the oxidation film.

与3Cr13合金相比，含5％volTiC颗粒的复合材料在850℃的抗氧化性能得到大幅度提高，而在950℃复合材料的抗氧化性能提高作用却是有限的；与1Cr18Ni9合金相比，含5％volTiC颗粒的复合材料在850℃的抗氧化性能略有提高，而950℃复合材料的抗氧化性能提高却是明显的；TiC颗粒可以提高两种基体合金抗氧化性能，主要是通过促进Cr的选择性氧化，进而改变氧化膜的相组成、减缓氧化膜内应力的产生、增加氧化膜/基体界面凝聚力及提高氧化膜化学结合力而实现的。
