The BDDcFⅧ gene was ligated behind PUB and 20H1 promotors to create lentiviral vectors pTK161 and pTK162. Meantime lentiviral vectors pTK161' and pTK162' were produced by cloning a green fluorescent protein into pTK151 and pTK152, which was driven by PUB and 2OH1 promotors respectively. Vector supernatant were prepared by using transfer calcium phosphate mediated-cotransfection of 293T cells. The virus vector,△NRF packaging-plasmid, and VSV-G envelope-plasmid was assayed by titers and cFⅧ activity in cell culture supernatant after infection into 293T cells.

用构建携带cFⅧ基因的慢病毒载体pTK161和pTK162（含20HI启动子），同时构建含绿色荧光蛋白的慢病毒载体pTK161'和pTK162'（含2OH1启动子）的方法，分别与包装质粒△NRF、包膜蛋白质粒VSV-G共转染293T包装细胞，将包装好的病毒颗粒再感染293T细胞，检测病毒滴度和培养细胞上清中cFⅧ活性。

With regard to the question how to cut the helical camber of screw-pump and spiral rod drilling tool in the field of petroleum machine and chemical machine, this paper firstly puts forward the cutting method how to apply the milling with non-instantaneous-pole envelope principle with plate milling cutter in our country.

本论文针对石油、化工机械领域螺杆泵、螺杆钻具转子的螺旋曲面切削加工问题，在国内首次提出了应用盘铣刀的无瞬心包络铣削加工方法。

Vaccinia virus belongs to the poxvirus family and has a double-stranded DNA genome of 192Kb in size. VV contains an envelope and replicates in cytoplasm of the infected cells. VV has a wide host range and infects various mammalian cell lines as well as animals.

牛痘病毒(Vaccinia virus， VV)属於痘病毒科中一拥有192kb双股DNA遗传物质的病毒，会在细胞质中繁殖出具有鞘膜的病毒，进而感染其他不同种的哺乳动物细胞和动物个体。

To save the pollen for later, brush it onto a piece of aluminum foil, fold the foil to make an envelope, and place in a freezer. It will last in the freezer for a month or so.

如果要保存这些花粉，那就把它们扫到铝箔上，折起来放冷藏吧，它们可以保存1个多月。

The RER, which is studded with polysomes, also seems to be the source of the nuclear envelope after a cell divides.

糙面型内质网，镶嵌在多聚核糖体中，也可能是细胞分裂后核膜的来源。
