Three expression vectors containing mutant gfp which were truncated from 3′ termine were constructed in the present paper.The mutation gfp with different length under the control by T 7 promoter were expressed in E. coli BL21 cells.

本文将突变型 gfp3′末端不同程度地截短，构建成表达载体，在大肠杆菌 BL 2 1中表达了不同长度的绿色荧光蛋白，当其生色基因中 65位 Ser点突变成 Thr，则 GFP的激发波由 396nm增至 4 70 nm，不用 UV激发，仅在自然光源下就可看到强烈的绿色荧光，发光强度增加 6倍，若从 3′端截短 12个氨基酸密码，对发光无影响，但截短 75个氨基酸密码，则激发波长降到 360 nm，发光强度减少 12倍。

Methods From April 1977 to December 2004,7 patients were admitted. There were 4 false aneurysms in aortic isthmus, and 1 right subclavian artery pseudoaneurysm, and 1 right axillary artery false aneurysm, and 1 thoracicoabdominal multiple pseudoaneurysms.

To prevent possible danger to the wind turbine struc-ture, it may be advisable to suppress the automatic untwisting at extremely high wind speeds (e.g. V ≥ 0.8 * Vref) and to have the yaw system control the plant automatically until these wind speeds have dropped to an acceptable level.

为防止风机结构上可能的危险，建议在风速极高情况下（如：V≥0.8*Vref）抑制解缆操作，且应使偏航系统自动控制机组，直到风速降到一个可接受的级别。

And Molly won seven shillings on a three year old named Nevertell and coming home along by Foxrock in that old fiveseater shanderadan of a waggonette you were in your heyday then and you had on that new hat of white velours with a surround of molefur that Mrs Hayes advised you to buy because it was marked down to nineteen and eleven, a bit of wire and an old rag of velveteen, and I'll lay you what you like she did it on purpose...

摩莉把赌注下在一匹名叫&永勿说&的马上，赢了七先令。然后坐那辆有五个座位的双轮破旧马车，沿着福克斯罗克回的家。当时你可风华正茂，戴着镶了一圈鼹鼠皮的白丝绒新帽。那是海斯太太劝你买的，因为价钱降到十九先令十一便士了。其实就是那么一点铜丝支着一些破破烂烂的旧丝绒。我敢跟你打赌，她准是故意的
