Were done and no positive reaction was found.5. The DNA of the young leaves of 132 Bt transgenic plants was extracted to do PCR Five positive inversion plants were obtained and the inversion rate was 3.8%.6. The DNA of fire positive inversion plants obtained in Dl generation was extracted and tested. Two stable positive inversion plants were obtained in D2 generations.7 The way of flourescent mirror flat was used to observe the pollen tube extension circumstance in the flower post after self-pollination.

Company every day noon 12: 00 to 13: 00 is the relaxation time, has eaten meal with the company colleagues also has half hour time, I work together with that SB LG on to stroll the family harmony, rolls on the ladder three buildings, on the bed lies down, on the chair sits, transfers gets down again the extension to the inexpensive goods special area, then directly soars the sweet tube special area, a person buys a sweet tube, returns to the company to go to work.

The results show that increasing the ball numbers and mandrel extension length may reduce the ovalization, but leads to more remarkable wall thinning; the ovalization becomes more severe with the larger bending angle; the smaller the relative bending radius, the larger the ovalization is; the ovalization and wall thinning degrees are both smaller in the case of pressure die with dry lubricant; and under the same bending condition, the ovalization of LF2M tube is larger than the one of 1Cr18Ni9Ti tube.

结果表明，增加芯头个数与芯棒伸长量都能减小弯管的截面畸变，但两者都导致弯管壁厚减薄量增大；随着弯曲角度的增加，截面畸变越严重，相对弯曲半径越小，无芯棒与芯头支撑段弯管的截面畸变愈严重；在压块无润滑情况下，弯管的截面畸变和壁厚减薄量都小，并且在同等弯曲条件下，1Cr18Ni9Ti弯管的截面畸变小于LF2M弯管。

In these cases, you may wish to use an extension tube with the mount to keep the image from appearing too high on the wall. We don't recommend tilting and using keystone correction on any 720p projector since it causes all signals, and native HD 720p in particular, to be rescaled.

在这些情况下，你可以考虑使用伸缩管进行吊装从而避免图像在墙面上显示过高（我们不推荐在任何720p 投影机上使用倾斜安装并使用梯形校正，因为这种方式使得所有信号，尤其是高清720p 信号，被重调（ dupin 注：不清楚此处 rescaled 的确切含义））。
