The calculation of relative variation of the negative feedback amplifier by differential method results in some errors under certain condition, so there was certain limitation in this method.

摘要利用求微分的方法计算负反馈放大器增益的相对变化量，由于在一定的条件下计算出的结果存在一定误差，因而使用这种方法具有一定的局限性。

Meta-analysis can prove the curative effect of extraoral support-type distraction on the craniofacial deformity secondary to cleft lip and palate.

此次Meta分析在一定程度上证实了口外支持式前牵张对唇腭裂继发颌骨畸形修复疗效，可为临床医师选择矫治颌骨畸形术式提供一定的指导。

The mycelial growth of Rhizoctonia solani was promoted by vanillic acid and syringic acid at levels of 0.1~1 mM/L, and it was inhibited remarkably by p-counaric acid of over 1mM/L and modestly by ferulic acid. The radial extent of mycelia of Fusarium solani was increased significantly by ferulic acid of 0.1~1 mM/L and limitedly by p-coumaric acid. vanillic acid had paradoxcial effects on the growth, positively at low levels and negtively at high levels, on which Syringic acid had a slight effect.

试验结果显示：浓度为0.1~1mM/L的丁香酸对西洋参立枯丝核菌菌丝生长具有促进作用，香草酸也有一定的促进作用，但不呈浓度效应，浓度在1mM/L以上的香豆酸对其有显著的抑制作用，阿魏酸也有一定抑制作用；对于西洋参根腐菌，阿魏酸对其生长有明显促进作用，香豆酸也有一定促进作用，香草酸表现为低浓度促进，高浓度抑制作用，0.1~1mM/L丁香酸对其生长基本无影响。
