氟

METHODS: We measured the effect of various lidocaine infusionson the MAC of cyclopropane, halothane, isoflurane, and o-difluorobenzenein rats.

我们测定不同的利多卡因输注对于大鼠环丙烷、氟烷、异氟醚和邻二氟苯 MAC 的影响。

A classic example of age-related reduced anesthetic requirement is the reduced minimum alveolar concentration necessary in elderly patients to produce anesthesia with either cyclopropane, halothane, isoflurane or desflurane.2 The requirement for these inhalational agents decreases linearly with patient age.

年龄相关性麻醉剂需要量减少，经典的例子是所使用的环丙烷、氟烷、异氟烷、地氟烷的 MAC 减少。这些麻醉剂需要量随年龄呈线性减少。

Gold becomes converted into a yellow deliquescent volatile fluoride when heated to low redness, and at a slightly higher temperature the fluoride is dissociated into metallic gold and fluorine gas.

黄金成为改为黄色潮解挥发性低氟当加热到发红，并在一个稍高的温度氟分为金属黄金和氟气分离。

Methods Enamel surface specimens were randomly allocated into 3 groups: 1 450 mg/L sodium fluoride dentifrice group, 1 450 mg/L sodium monofluorophosphate dentifrice group and non-fluoride dentifrice control group. Sound enamel surfaces were dematerialized in bacteria model in vitro. QLF was used to analyze the area of lesionsArea, the loss of fluorescenceΔF and ΔQArea×ΔF on enamel surfaces after demineralization.

将30个牙釉质块开窗后分为3组，分别使用氟含量1 450 mg/L的氟化钠牙膏、单氟磷酸钠牙膏和无氟牙膏的处理液处理，并在体外恒化器龋病模型中进行脱矿循环，定量光导荧光技术QLF分析病损脱矿后的面积、荧光损失和总荧光损失量，激光扫描共聚焦显微镜CLSM分析脱矿后矿物质含量变化。

After the diazotization, a mixture of 2,3,5-trichloropyridine and 3, 5- dichloropyridine-2-ketone was got as a result of Sandmeyer reaction.

收率达84.7%。接着，我们以制得的2，3，5-三氯吡啶为合成2，3-二氟-5-氯吡啶的原料，用NMP为溶剂，加入KF和CsF的混合氟化剂，高温下反应合成了2，3-二氟-5-氯吡啶。

The reaction of perfluoroalkyl bromide and a,w-perfluoralkylene dibromide in sulfinatodehalogenation system with olefins and the differences in behavior between perfluoroalkyl bromides and their corresponding iodides are reported.

The results showed that under different doses the hemolytic index of the gelatin microspheres was lower than 5%, so it did not have significant toxicity; primary skin irritation test showed there were no erythema, eschar and edema of 10% florfenicol gelatin microspheres injection; the LD50 of the microspheres was 2.226 7 g/kg and its 95% credibility limit was 1.950 2~2.635 6 g/kg.

实验结果显示，不同剂量的肺靶向氟苯尼考明胶微球注射剂的溶血指数均小于5%，无明显毒性；10%氟苯尼考明胶微球注射剂对受试动物皮肤无明显刺激作用；肺靶向氟苯尼考明胶微球对小鼠的LD50为2.226 7 g/kg，LD50 95%的可信限为1.950 2 ~2.635 6 g/kg。

The condition and efficiency of removing fluor of this material were studied.

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。
