原文如下：

Select atoms that became 'too small'

By default, the size of the atom displayed on the screen is proportional to its ADP or Uiso. If the atom type is wrong, and the real element is much heavier, the Ueq will become very small and therefore the displayed sphere will be too small to select by mouse. There are two solutions to this problem:

1) You can select an area that includes the atom you wish to select by drawing a box around the atom with the Shift key and the left mouse button pressed simultaneously.

2) You can switch the view to a Ball and Sticks display (View>Quick Drawing Styles) or type:

>>pers

Also use (or the GUI):

>> telp

to switch back to the view when the atoms' proportional Uiso and ADP's are displayed.

譯文如下：

3.12. 選擇變得“太小”的原子

默認(rèn)情況下，屏幕上顯示的原子大小與其ADP或Uiso成比例。若原子類型錯(cuò)誤，并且實(shí)際上是更重的元素，Ueq將變得非常小，因此顯示的球體將太小以致于無法用鼠標(biāo)選擇。有兩種解決方案：

1)你可以通過同時(shí)按住Shift鍵和鼠標(biāo)左鍵在原子周圍繪制一個(gè)方框，可以選擇包含要選擇原子的區(qū)域。

2)你可以將視圖更改為球棍模型——Balls & sticks(View>Quick Drawing Styles)或鍵入：

>>pers

也可使用(或GUI)

>>telp

用于切換回原子以Uiso和ADP成比例顯示的視圖(即橢球圖——Ellipses& sticks)。
