#       Cylinder specification: set this to 9.0 or if you did from pymol.cgo import * you can then use "CYLINDER", here.

#怎么设置透明度
#a1, a2
#a1=25.0或者用ALPHA
#        a1=25 means 'ALPHA' (if you do from pymol.cgo import * you can then use CGO keywords
# etc. So, if a1="25.0" then set a2 to some value in the range 0-1.
#a2为透明度
#a2=0 全透明，a2=1不透明

#再看效果的时候，一定要先ray然后再看
#先关闭all，然后先看不透明，然后再看透明的物体，这样才能看到效果
