氟

The mechanism was supposed as follows: polyfluoroalkyl iodides were initiated by sodium dithionite to give R〓 which was added to one double bond of diallylacetic acid, after the sequential radical cyclization and nucleophilic substitution to form bicyclo-lactones.

这是因为：多氟烷基碘化物在连二亚硫酸钠的引发下，得到自由基R〓，后者加成到二烯丙基乙酸中的一个—C=C—双键上，然后在碱性介质中进行分子内亲核反应得到双环内酯类产物。

In the paper a new technology of divorcement cerium from rich lanthanum rare earth in bastnaesite was studied .

I also have this situation Jiabao began to think that it is lit and then the same as tears, and later the eyes were眼屎paste all day long, and the eye is red, so the children go to the hospital two months security, only to remind doctors to of view, said to be probing, so that the first drop of the week again pass eyedrops, eye drops and then write a call to buy our own, 3% ofloxacin eye drops, it is necessary to sort in Japan, I bought the a bottle of 31 money, drops three times a day, a drop of just one week, the眼屎with no tears, and dripping the ninth day to the hospital, doctors say that it no longer had.

我家宝也有这种情况，开始以为是上火，先是像流泪一样，后来眼睛整天都被眼屎糊着，眼周都是红的，到两个月去医院做儿保，医生提醒才去看，说是泪囊炎，让先滴一周眼药再去通，然后写了一个眼药水叫我们自己去买，3％氧氟沙星滴眼液，要日本产那种，我买的是31块钱一瓶，一天滴三次，滴了刚好一周时候，就没有眼屎跟眼泪了，滴到第九天去医院，医生说已经好了，不用再通了。

Results: The proportion of Gram-negative bacilli rose obviously, so did the opportunistic pathogen's and Yeasts detected rate. Most drug sensitive tests showed the drug-fast rate turned to be high. Escherichia coli, Salmonella and Citrobacter resistant and so on to fluoroquinolones was 57%~97%. These bacteria to imipenem showed excellent activity. Meticillin-resistant-staphylococcus resistant to ciprofloxacin, norfloxacin, clindamycin, tetracycline, erythromycin, cefazolin and ampicillin were 40.9%, 42.4%, 63.6%, 72.2%, 85.9%, 100.0% and 100.0%, respectively Streptococcus and Enterococcus resistant to major β-lactams-penicillin, aminoglycosides, macrolides, tetracyclines and sulfonamides were between 36.0% to 100.0%.

结果：革兰阴性杆菌比例显著升高，条件致病菌和酵母样真菌检出机会显著增多；药敏结果显示多数临床细菌对常用抗生素的耐药趋势在不断上升；大肠埃希菌、沙门菌和枸橼酸杆菌等革兰阴性杆菌对喹诺酮类药物的耐药率达57%~97%，亚胺培南则对阴性杆菌有较高的敏感覆盖率；耐甲氧西林葡萄球菌对环丙沙星、诺氟沙星、氯洁霉素、四环素、红霉素、头孢唑啉和氨苄西林的耐药率分别为40.9%、42.4%、63.6%、70.2%、85.9%、100.0%和100.0%；链球菌和肠球菌对多数β内酰胺类青霉素、氨基糖苷类、大环内酯类、四环素类以及磺胺类药物均呈高度耐药，耐药率在36%~100%。

To Dec. 2003 years in Yuxi city People's Hospital. RESULTS: The proportion of G－ bacilli were much. The opportunistic pathogen's and Yeasts detected rate rose obviously. Most drug sensitive tests showed the drug-fast rate turned to be high. Escherichia coli, Salmonella and Klebsiella and so on to fluoroquinolones was 50～97.7%. These bacteria to imipenem showed excellent activity. MRS resistant to ciprofloxacin, norfloxacin, clindamycin, tetracycline, erythromycin, gentamycin, trimeth/sulfa and cefazolin were above 50%. Streptococcus resistant to major β-lactams-penicillin, aminoglycosides, macrolides, tetracyclines and sulfonomides were highness.

结果：G－杆菌比例居多，条件致病菌和酵母样真菌检出机会显著增高；药敏结果显示多数临床细菌对常用抗生素的耐药趋势在不断上升；大肠埃希菌、沙门菌和克雷伯菌等G－杆菌对喹诺酮类药物的耐药率在50％～97.7％，亚胺培南则对阴性杆菌有较高的敏感覆盖率；耐甲氧西林葡萄球菌对环丙沙星、诺氟沙星、氯洁霉素、四环素、红霉素、庆大霉素、复方新诺明和头孢唑啉的耐药率均在50％以上，链球菌对多数β内酰胺类青霉素、氨基糖苷类、大环内酯类、四环素类以及磺胺类药物呈高度耐药。

The study on effective gain cross section shows that there is a flat gain shape between 1530～1580 nm, which proves that the wide-band property of the glass is much better than that of phosphate glasses.

对反映宽带性能的有效增益截面的研究表明，该镱铒共掺氟磷酸盐玻璃在1530～1580 nm之间有一平坦的有效增益截面谱线，证明其宽带特性明显优于掺铒磷酸盐玻璃。
