因此，针对声源方向感受此一课题，以两反射音之模拟声场进行实验探讨，研究方法不仅以数理解析，并针对人们实验的心理感受进行调查分析，心理实验时采用配对比较法及恒常性图解法统计分析，试图藉由若干变因的控制进行量化，实验结果发现声源方向感度的变化，主要受制於双耳互函数级数及全反射音振幅的大小，双耳听觉互函数主要与反射到达测听者的方向和反射的幅度有关，证实声源方向感度与双耳互函数级数为正比之关系存在。

A systemic research on the birefringence of side-hole fiber is presented. The research results show that the birefringence of circular-core side-hole fiber relies mainly on stress birefringence, its fast axis is parallel to the link line of the two holes, and its intrinsic birefringence increases exponentially with the angle and ellipticity of side holes.

本论文的主要研究结果和创新在于： 1、对边孔光纤的双折射特性进行了系统研究，提出圆芯型边孔光纤以应力双折射为主，两边孔连线方向为其快轴方向，其双折射大小与边孔张角和边孔椭圆度成指数关系。

With the characterization of NMR and IR, combining with the synthesis of active species and studies of their structures, it is suggested that the hydride [RuHCl(PPh3)3], being favorably formed in the acid media, exhibited higher activity in the reduction of the C=C bond, while the hydride [RuH4(PPh3)3], being preponderantly formed in the basic media, showed activity and higher selectivity towards the C=O reduction.

通过核磁、红外等表征手段，并结合可能催化活性配合物的合成和结构研究，推测了在非水介质中对C=C和C=O双键起到活化作用的催化剂活性物种和可能的选择加氢反应机理，即，催化剂[RuCl2(PPh3)3]在酸性环境下倾向于生成[RuHCl(PPh3)3]物种，该Ru-H物种对C=C双键加氢反应表现出较高的活性；而碱性环境下则易于生成[RuH4(PPh3)3]物种，该Ru-H物种对C=O双键加氢具有较高的催化活性。
