氟

In the complex system of MeSO4, the removal of Ca2+ and Mg2+ by fluorination precipitation and double salt precipitation deep purification process was studied by single factor method.

分别以浸出液和氟化沉淀液为原料，采用单因素法对复杂MeSO4体系氟化沉淀除钙镁和复盐沉淀深度净化进行了研究。

Satisfied the need of the research in preparation of fluorine by electrolyzation and the second-degree purifier further secured the whole operating system of the experiment besides purifying the fluorine gas.

实验研究表明：所研制的电解槽、化学冷却阱、吸收塔，防爆缓冲罐，尾气环保装置等设备设施可以满足本研究电解制氟的需要，且二级纯化装置不但具有纯化氟气的功效，而且还可对整个实验操作系统起到进一步的安全保障作用。

Furthermore, compared with the tautomerizing processes of uracil, the probability of 5-FU to tautomerize to its enol form is much higher. Based on such facts, the reason why 5-FU is an effective anticancer medicament but with some of toxicity is explained to some extent.

通过与尿嘧啶质子转移过程相比较，发现在各种情况下5-氟尿嘧啶异构化为烯醇式的几率均比尿嘧啶的大，在一定程度上解释了为什么5-氟尿嘧啶具有优良抗癌作用的同时具有一定的毒副作用。

Inconclusion, equipotent concentrations of desflurane or sevofluranein terms of BIS are associated with similar rSO2 values, butlarger anesthetic concentrations of both anesthetics increasedthe rSO2 values.

结论，在 BIS 方面等效浓度的地氟醚和七氟醚具有相似的 rSO2值，而两个麻醉药的较大麻醉剂浓度能提高 rSO2值。

Have a first-class domestic and international cable production and testing equipment, the main products are PTFE insulated wire and cable, FEP insulated wire and cable, PTFE insulated RF cables, UYS series of cross-linked ethylene - tetrafluoroethylene insulation such as wire and cable.

拥有国内外一流的线缆生产及检测设备，主要产品有聚四氟乙烯绝缘电线电缆、聚全氟乙丙烯绝缘电线电缆、聚四氟乙烯绝缘射频电缆、UYS系列交联乙烯-四氟乙烯绝缘电线电缆等。

Second,the development trend and research status of fluoroquinolones was presented. Fluoroquinolones,which were newly-developed oral comprehensive antibiotics in recent years,has fairly strong flurorescent quality and therefore is used to explore the functional mechanism of drugs in human bodies,by the change of fluorescent extensity between fluoroquinolones and protein,as well as metallic irons.

其次是氟喹诺酮类药物的发展趋势及研究进展，氟喹诺酮类的药物是近年来迅速发展的口服广普抗菌药，具有较强的荧光特性，因此可以利用其与蛋白质及金属离子相互作用时荧光强度的变化来研究药物在人体内的作用机制等。

After LASEK, the patients in the therapeutic group were given high-dose glucocorticoids (6 times daily for the first week, 8 times daily for the second week, 6 times daily for the fourth week, after three-months, an gradual extenuation was performed post-trimonth) after LASEK.

导读：常用的皮质激素眼液有百力特、氟美瞳、点必舒等；百力特作用强且持续作用时间长，升眼压作用明显，不适作长期使用；氟美瞳滴眼液浓度低作用温和，升眼压作用小，相对较安全，故作为首选。

Fluorine and phosphorus were measured with electrochemical analysis and spectrophotometry;the ratio of F to P was calculated.

清除结石，用优级纯硝酸冷消化处理后，分别采用电化学分析法和分光光度法测定离体牙氟和磷的含量并计算氟磷含量比。

A first derivative spectrophotometric method is presented for the determination of fleroxacin in tablets, capsules and powder for rejection.

用一阶导数分光光度法测定了氟罗沙星片剂、胶囊和粉针剂中氟罗沙星的含量。

After the fluoride into the tooth germ, it is in the developmental stage with the enamel crystals react fluorapatite began to replace the hydroxyapatite.

进入后牙胚氟，它在牙釉质晶体的发展阶段，是氟磷灰石反应开始取代羟基磷灰石。

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。
