The pI of these components gradually decreased f rom pH 4.0 according to electrophoresis mobility from higher to lower on PAGE. The molecular weights were in the range of 22～34 ku. 6.5 and 7 w ere glycoproteins proved by staining with the shiff reagent and thymol/sulfuric acid. The fibrinolytic activity of 7 was highest as determined usi ng chromzym UK and chromzym PL as specific substrates.

这些组分的等电点按照它们在聚丙烯酰胺凝胶电泳图谱上的顺序从4.0开始依次降低；SDS-PAGE证明，除3、4外，其余组分均只含一种多肽链，分子质量在22～34ku之间；用shiff试剂和酚-硫酸染色，显示1、2、6.5和7是糖蛋白，其中7的糖含量最高；以BAEE、Chromozym UK和Chromozym PL为底物测定，7的纤溶酶活性最高。

Company's main products, such as titanium dioxide and polyferric sulfate.

I was pregnant in 2007, when a to 6 months, when a sudden high fever, and after go to the hospital has been the rule in accordance with upper respiratory tract infection, and spent the first cell, Shuanghuanglian, but also There Chaihu failed to bring down a fever, and later a blood test that mycoplasma infection, with the azithromycin, on the night a night to hang out bottles, anti-fever the morning, go home and sleep until the afternoon began to have stomach pain and the law hard fat and a bloody discharge, but also the beginning of fever, rushed to the hospital, the doctor so that the results do a good B-fetal heart rate is 190 too, and contraction, the latter with a magnesium sulfate Baotai hospital but still could not suppress Palace reduction, and finally failed to keep, artificial rupture of the amniotic fluid that is some pollution, after giving birth, nor fever, the doctor also did not say clearly how the matter in the end, only that it might be likely to lead to a fever have been premature, but I just fever other cold symptoms are not.

请姐妹们帮忙看一下！！！我在07年的时候怀过一个，到6个月的时候，突然发高烧了，去医院后一直是按上呼吸道感染治的，用了头胞，双黄连，还有柴胡都没能退烧，后来验血说是支原体感染，用了阿奇，就那一晚上挂了一夜掉瓶，早上退烧了，回家睡觉，到了下午肚子开始有规律的疼而且发硬并且有血性分泌物，而且又开始发烧，赶紧到医院，医生让做B超结果都好就是胎心过快190，有宫缩，后住院保胎用了硫酸镁但是还是抑制不住宫缩，最后没能保住，人工破水说是羊水有些污染，生完宝宝后，也不发烧了，大夫也没说清楚到底是怎么回事，只是说可发烧本来就可能引发早产，但是我只是发烧别的感冒症状都没有。

The mass transter can be enhanced ,when we introduce sulfuric acid and cuprous oxide into this system.The model is formed to describe the transference of the martial between the four phases: gas-liquid-liquid-gas, which can explain some problems. We analyze the dead of the catalyst, and make a conclusion that the surface of the catalyst is covered with some compounds such as bluestone, which lessen the activity points of the catalyst and debase the activity.

在SO_4~(2-)／ZrO_2-La_2O_3催化的反应系统中加入稀硫酸和氧化亚铜促进了异丁烯和一氧化碳的传质、使反应得以快速，高选择性的进行，异丁烯的转化率达95％以上，特戊酸的收率达47％；讨论了g-l-l-s传质过程；对催化剂作了失活分析，催化剂失活的原因是因为反应后的催化剂表面覆盖了一层硫酸盐，使催化剂的活性中心数减少，活性降低。

Under the conditions of microwave heating of 1 h, sul- furic acid concentration 8.0 mol/L and liquid/solid ratio 5.0 mL/g, most of the minerals in tailings can be dissolved except tremolite.

微波加热条件下，尾矿砂在硫酸浓度8mol／L、液固比5.0mL农条件下无需搅拌，反应1h后，除透闪石没有完全溶解外，绝大部分的矿物被溶解。

Under the conditions 0f microwave heating of I h, sulfuric acid concentration 8.0 mol/L and liquid/solid ratio 5.0 mL/g, most of the minerals in tailings can be dissolved except tremolite.

微波加热条件下，尾矿砂在硫酸浓度8mol/L、液固比5.0mL/g条件下无需搅拌，反应1h后，除透闪石没有完合适溶解外，绝大部分的矿物被溶解。

The discharge print by using stannous chloride can be possible on polyester, Acetate, Triacetate, Polyacrylic and its blend with Polyamide fabrics.

在用硫酸氯烂花印花上，该产品可以提供非常好的效果。模具印刷和更高的糊剂稳定性是一项额外优势。

Taking glycerol and ethanoic acid as raw materials,the glceride triacetate was synthesized with ion liquid pyrrolidone hydrosulfate as catalyst.

目前工业生产基本采用丙三醇和乙酸用浓硫酸催化生产三醋酸甘油酯。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
