摘　　要：本文介绍溶液降温法生长的大块邻苯二甲酸氢铷(RAP)单晶中关键有机基团的取向和性质对晶体生长习性的影响,并阐述结构中分子松散堆积与缺陷形成之间的关系。Large perfect crystals have been grown by using (001) seed plates from aqueous solution. It is shown that the great difference in the growth rates along positive and negative a-axis directions and the defect formation are closely related to the orientation of the key groups of carboxyl radicals(I) and the open structure (mainly the structural channels A and B), respectively. A proposal for improving the quality of crystals by changing the orientation of the polar axis a is given.
