氟

A test of chronic fluorosis was done in chickens to study the effects of high fluorine on micronucleus rate.

为探讨高氟对鸡微核率的影响，实验组鸡饮用不同浓度的含氟水，对照组鸡饮用正常自来水，比较两组微核率，用χ2检验方法作显著性检验。

In 1886, french chemist moissan, combining experiences from people before him, successfully isolated fluoride. he then proved that fluoride could react with most of the elements. he received 1906 nobel chemistry award.

1886年，法国化学家莫瓦桑，集结前人的经验，成功分离出氟，其后并证明氟几乎能和绝大多数元素产生反应，使他获得多国奖章，并於1906年获颁诺贝尔化学奖。

We usedit as the macroinitiator,(copper monochloride/pentamethyldiethylenetriamine as thecatalyst), to initiate the atom transfer radical polymerization of Fx-14, thus weobtained a fluorine and silicone containing triblock copolymer.

以此聚合物为原子转移自由基聚合中的大分子引发剂，引发含氟单体Fx-14进行原子转移自由基聚合，得到了含氟、含硅的三嵌段共聚物。

The Cause for the accumulation of fluoride in Antarctic krill is studied by the analysis of the characteristics of fluoride change in the cuticle of the krill before and after moulting.

In order to understand the mechanism of the detoxication of the fluoride poisoned silkworm by naphthylamine compounds such as CRL, the effect of CRL on the activity of the glutathione peroxidase in the hemolymph of fluoride poisoned silkworm larvae was studied.

摘 要：为了解萘胺类化合物CRL缓解家蚕氟中毒的机理，研究了CRL对氟中毒家蚕幼虫血淋巴中谷胱甘肽过氧化物酶活性的影响。正常的家蚕5龄幼虫血淋巴GSH-Px在龄的中期活性较强，龄初和龄末活性较弱。

The effects of the reaction temperature, the ratio of fluorous phase and organic phase and the water in the reaction system on the nitration were investigated.

考察了反应温度、氟相和有机相的体积比与体系中的含水量对氟两相硝化区域选择性的影响。

After remineralization, the surface structure of samples in Chinese nutgall group and Ag（ NH3 ）2F group became compacter and steadier, with presentation of small blotch and trabs; in NaF group, there was still laeune with trablike structure on the surface of the samples; in deionized group, the surface of samples was honeycomb appearance.

再矿化后，五倍子液和氟化氨银液组表面结构更加致密，均匀，呈小斑块，条索状；氟化钠液组表面也出现条索状结构，但仍有孔隙或腔隙存在；去离子水组表面出现蜂窝状结构。

RESULTS: Before remineralization, through SEM, short blunt eeptoma was found on the surface of lesions of samples in Chinese nutgall group and Ag（ NH3 ）2F group; while in NaF group, globular ecptoma was seen scattering on the surface of the lesions, together with laeune; in deionized group, there was Sharpey＇s fiber.

结果：再矿化前，扫描电镜观察五倍子与氟化氨银处理后牙骨质龋表面形成不规则短钝状突起；氟化钠液组形成大小不一的散在大球状突起，可见一些腔隙存在；去离子水组大量分布夏伯氏纤维。

Group I was the control ,and other four groups ,groupⅡ,Ⅲ,Ⅳ,Ⅴ were fed the diets containing 500,1 000,1 500,2 000 mg/kg of fluorineass odium fluoride, respectively, for 150 days.

第1组为对照组，第2，3，4，5组在日粮中添加不同水平的氟化钠，使日粮中氟含量分别为500，1 000，1 500，2 000 mg/kg，实验期150 d。

Previous investigations have shown that halothane preservescardiac parasympathetic activity more than sevoflurane.

过去的研究显示氟烷比七氟醚更多保护心脏的副交感活性。

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。
