疏

The majority of the students thought of the lack of practice or contact as the main factor in their difficulty to master writing and oral skills.

而大部份学生都认为疏於练习或难於接触，是导致他们难於掌握书写语文及对话的主要因素。

Meanwhile, several physicochemical descriptors of xanthone molecules were calculated by using quantum chemistry method.

同时，运用量子化学计算了山酮分子的物化参数，并选择相互作用能、疏水常数(log P；其中P为正辛醇-水分配系数)和山酮分子总能量作为分析结构-电泳迁移定量关系的物化参数，用以研究分离机制及在毛细管区带电泳分离中山酮类化合物与β-CD 和磺酸化β-CD间的分子识别过程。

Meanwhile, several physicochemical descriptors of xanthone molecules were calculated by using quantum chemistry method. Among the physicochemical parameters, interaction energy, the logarithms of octanol-water partition coefficient and total energy of xanthone molecules were selected to investigate the separation mechanism and describe molecular recognition process between the xanthones and the CDs in CZE by means of quantitative structure-electromigration relationships.
