Test separately to raw materials grain size , raw materials matching , frit such craft parameters as temperature , time of fritting ,etc.

试验分别对原料粒度、原料配比、烧结温度、烧结时间等工艺参数进行优化，得出制备抗菌吸附颗粒制备的最佳条件：当原料粒度为320目，分别加入总质量7%的废玻璃粉和粘土，加入0.5%的硝酸钠做助熔剂，以硅胶溶液造粒，450度烧结1.5小时可以获得吸附抗菌效果最佳的陶瓷颗粒。

This two species of Gloiopeltis could mature and release spores at illuminance 2 500~8 500 lx. For no nutrient addition to the stocking water the two species of Gloiopeltis could mature and release spores, while nutrient addition too high (80 mg·L-1 NaNO3 and 8 mg·L-1 KH2PO4) it was not good for the mature and spores release of this two species alga.

结果表明，在水温10~20℃培养条件下，海萝能成熟放散孢子；在水温12~24℃时，鹿角海萝能成熟放散孢子；在光照2 500~8 500 lx的范围内，2种海萝均能成熟放散孢子；培养海水中不添加营养盐对这2种海萝的成熟没有影响，培养液的浓度高达硝酸钠80 mg·L-1、磷酸二氢钾8 mg·L-1时反而不利于藻体的成熟及孢子放散附着。

The modified product conditions of MELs were: 9% refine soybean oil and 3. 6% kerosene , 2. 0% NaNO〓, 0.08% yeast extract, 0.02% KH〓PO〓, 0.02% MgSO〓·7H〓O, 10ppm EDTA.

1甘露糖赤藓糖醇脂的改良工艺条件为：以9％的精制豆油+3.6％的煤油为碳源，氮源采用2.0％的硝酸钠，酵母浸膏0.08％，KH〓PO〓 0.02％，MgSO〓·7H〓O 0.02％，EDTA10ppm。

The 16S rDNA analysis indicated the strain had a 98.2% of homology with Pseudomonas aeruginosa. Its best carbon source is glucose and sodium acetate, and the best nitrogen source is ammonium chloride、nitrate and peptone.

该菌的良好碳源和氮源是葡萄糖、乙酸钠和蛋白胨、氯化铵、亚硝酸钠复合成份，纤维素不适合作为该菌的碳源。

Experimental study on the metal surface cleaning agent re-oil preparation process of the series,Obtained by experiment the optimum cleaning process conditions:2g respectively SDBS,2g sodium silicate,2g sodium nitrite dissolved in 100 ml of distilled water,making the steel sheet coated with oil immersed in cleaning agents,under the conditions which keeping the washing temperature 30℃,Stirring rate of 2 files,Cleaning time for 5 min of the cleaning Cleaning the oil to achieve the highest rate of 99.62%,Corrosion rate can be controlled below 0.006%.

实验研究了金属表面重油污清洗剂制备的系列工艺，通过实验得出其最佳的清洗工艺条件：分别取2g十二烷基苯磺酸钠、 2g硅酸钠、2g亚硝酸钠溶于100毫升蒸馏水中，将涂有油污的钢片浸入清洗剂中，在清洗温度为30℃，搅拌速率为2档，清洗时间为5 min的条件下清洗，其油污清洗率最高能达到99.62%，腐蚀率能控制在？以下。
