The results show that the decay of retinol and retinyl acetate are much faster in anionic micelles than that in cationic micelles and neutral micelles(TX-100), which indicate that the decay is carried out by the protonation of retinol or retinyl acetate first, then one molecular water or acetic acid is lost to produce the carbonium ion, which release the proton followed to generate the anhydroretinol.

ETHODS: The gastrocnemius bundle branch and soleus muscle bundle branch of the right achilles tendon were sutured after surface skin and subcutaneous tissue discission. The gastrocnemius bundle branch was transected at 2 cm above calcaneal bone insertion and a 2-cm silicone tube was applied to separate the site of suture using 5-0 modified Kessler method. The site of suture was treated with nothing in silicone tube as the blank control group. In other three groups, the site of suture was treated with 100, 50, 10 ng VEGF in silicone tube at the operation day and 7, 14, 21 days post-operation.

Calculating with the data supplied by the soft X-ray station and from our observation, in the usual dedicated mode with multi-bucket in the storage ring the output of diamond detector should have an amplitude of order 2μV, assuming 500ps-wide, when injected by a homochromous light at 1keV with 1%BW. In the dedicated mode with single-bucket the peak power of the pulse light will be the largest, maybe an order larger than with multi-bucket.

我们根据软X光站提供的数据和实际观察结果推算，在常用的专用模式多束团运行时，如果以1keV能量处1％BW的单色光入射，金刚石探测器输出信号以500ps的半高宽计算，幅度应有2μV的量级；专用模式单束团运行时能达到最高的光脉冲峰值功率，可能比多束团大一个数量级。
