SF〓 is widely used in high-voltage circuit breakers because of its excellent insulating performance in uniform electric field.

SF〓气体由于在均匀电场中具有优异的绝缘性能，在高压断路器中得到广泛应用。

By much expriment, this thesis discovers the the vacuation of whole cable insulation can be replaced by that of polymer particles. Then cable insulation is immpregnated by filling SF〓 into cable core.

本文经过大量对比和模拟实验发现，粒料的抽真空浸渍可以代替电缆绝缘的抽真空过程，由于粒料体积小，其抽真空浸渍容易完成；然后再在电缆线芯充SF〓气体对电缆绝缘进行浸渍。

Objective To clone the Bombus ignitus venom protease gene screened from the expression sequence tags of the bumblebee, Bombus ignitus and express it in Spodoptera frugiperda Sf-9 cell.

目的 克隆表达序列标签中筛选出的红光熊蜂蜂毒蛋白酶基因，在草地夜蛾细胞Sf-9中进行表达。

Methods The BiVP gene was screened by the ESTs technology and cloned by PCR method from the cDNA library of the bumblebee, Bombus ignitus. It was reconstructed to form the baculovirus transfervector pBac1-BiVP and expressed in Sf-9 insect cell. The recombinant BiVP was purified by the fast protein liquid chromatography system.

利用ESTs从红光熊蜂cDNA文库中获得BiVP基因，以PCR技术扩增出BiVP的完整cDNA，并构建病毒表达载体PBac1-BiVP，通过昆虫杆状病毒表达系统，在Sf-9昆虫细胞中进行表达，表达产物用快速蛋白液相色谱系统进行纯化。

There's a very poignant scene in Gateway -- and this was the first time I'd read something like this in SF -- where the main character, Robinette Broadhead, had become friends with a handicapped person who wanted to go on this space voyage with Robinette.

GATEWAY 里面有一个非常POIGNANT的场景——这也是我第一次在SF里看到——主角ROBINETTE BROADHEAD与那位想和他继续星际旅行的HANDICAPPED PERSON成为了朋友，并对他说：'当然可以，我们是兄弟。

Had done a lot of websites before, but do not have a few successfully, in 7 years when do SF to release a station the month has been entered in those days tens of thousands of, but good times don't last long, slowly downfallen, but we did not abandon making a station all the time, held to now, this year I come to A5 this big family.

以前做过很多网站，但是成功的没有几个，在07年的时候做SF发布站那时月入好几万，但是好景不长，慢慢就没落了，但是我们一直没有放弃做站，坚持到了现在，在今年我来到了A5这个大家庭。

Improvement in QOL, as evaluated by the LASA, KDQ and SF-36 instruments, was generally similar in both groups.

通过LASA，KDQ 和SF-36 设备评估在两个目标组QOL的提高类似。

While AcMNPV and BmNPV had no stimulatory effect in nonsensitive cell lines BmNPV hr3 has been demonstrated to increase the transcriptional activity of cislinked hel510 promoter. In this study, Sf-21, Bm-N and Hi-5 cell lines were transfected with pBmhel510luc-hr3down, and then were infected with each of AcMNPV, BmNPV and HyNPV. The results indicated that viral factors could interact with hr3 to significantly copromote the transcriptional level of hel510 promoter.

BmNPV hr3已被证明具有增强子功能，将hr3与hel510启动子顺式连接的质粒pBmhel510luc-hr3down转染Sf-21、Bm-N和Hi-5细胞后，再用上述三种病毒分别感染每一种细胞，hel510启动子的转录活性得到显著提高，表明病毒因子能够识别hr3，二者通过相互作用，共同增强解旋酶基因启动子的转录水平。
