氟

Methods:Is poisoned case of illness the fluorine acetamide stochastically to divide into the treatment group and the comparison group, two groups both use the conventional treatment, in this foundation, to treats the group case of illness after to be poisoned a week to give the niter benzene even treatment.

目的：研究硝苯地平对恢复期氟乙酰胺中毒患者的脑电图的影响方法：将氟乙酰胺中毒病例随机分治疗组和对照组，两组都使用常规治疗，在此基础上，对治疗组病例在中毒1周后给予硝苯地平治疗。

First, the speed of the reaction between mud acid and rock is very fast, the effective distance of acid is short, active acid can not reach deep formation.

首先，高温下常规土酸与地层矿物反应速度极快，酸液有效作用距离短，活性酸不能到达地层深部；其次，HF与铝硅酸盐的化学反应不是简单的一次反应，其副产物氟硅酸和氟铝化物还可与铝硅酸盐发生二次反应和三次反应，形成一系列不溶性的沉淀物，对储层造成严重伤害；第三，高温情况下酸液对井下管柱及工具腐蚀性很强，对缓蚀剂性能要求高。

This paper relates to the preparation of phosphorus pentafluoride and the solubility of phosphorus pentafluoride in aether.

本论文对以五氧化二磷和无水氟化氢为原料制备五氟化磷的工艺和五氟化磷在乙醚中的溶解度进行了初步研究。

Also need to know is: If the air-conditioning units a year on the need to increase fluoride, it is first necessary to repair leakage site, and then with fluoride.

还需要了解的是：如果空调机一年就需要加氟，则首先要修理漏气部位，然后再加氟。

In the paper, the test results about fluorine retention in the alkaline-earth metal compounds combustion were studied to develop high-efficient fluoride retention additive.

为了开发高效燃烧固氟剂，通过实验研究了碱土金属化合物的燃烧固氟效果。

The vast majority of these polymers after combustion split into fluorinated alkene, while the fluorinated alkene is that it may cause cancer substances.

指出，这些聚合物燃烧后绝大部份分裂为氟化烯，while的含氟烯烃认为它可能是导致癌症的物质。

The histiological characteristcs, and activities of alkine phosphatase and acid phosphatase of the implantan were examined to study the effects of fluoride on biological activities of BMP.

结果 氟对BMP的生物活性有直接的影响，氟能促进BMP将更多的成纤维细胞转化为成骨细胞，并能增强成骨细胞的功能，加速钙盐沉积，而破骨细胞功能有所下降。

By research on developing and utilizing of analcite muddy rock resources in Ningxia,the technique of using analcite to decline fluoride water including purifying,deforming,and modeling,this paper mainly studied removing rate and adsorbing capacity of fluorine ion in high fluoride water .

为了探讨开发利用宁夏境内含有方沸石矿物的泥质岩石资源，通过提纯、变性、造型等技术手段和工艺研制了方沸石矿物降氟改水新材料，并对高氟水中F-的去除率和吸附容量进行了研究。

When 0.02 mol/L NaOH solution is employed as the anolyte, the removal rates are 25.9%, 31.2% and 47.3% with 1.0, 1.5 and 2.0 V/cm voltage gradient respectively.

结果表明，1.0 V/cm电解电压下，当阳极电解液为去离子水时，氟在阴、阳极电解液中的累积量分别为8.2 mg和47.7 mg，土壤氟的去除率仅为8.8%。

Dichlorodifluoromethane and Difluoroethane, Azeotropic Mixture

氯氟 烷和氟烷的共沸混合物，含约74%氯氟烷2602

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
