In our experimental results, we have transferred the GaAs solar cells from GaAs substrates onto the mirror-coated copper substrates with the base layer thickness of 1.5 μm. The photovoltaic performance of the orginal GaAs solar cell on a GaAs substrate was also measured. Under AM1.5G and without anti-reflective coatings conditions, it is found that the Jsc can increase from 12.6 mA/cm2 to 13.82 mA/cm2, while the conversion efficiency can improve from 7.91% to 8.53%. As a result, the enhanced Jsc and η data of the GaAs solar cells can be contributed by the AuGe/Au mirror between the GaAs solar cell and copper substrate.

在实验验证方面，本实验室将砷化镓太阳电池由砷化镓基板转移至铜基板上，在基极厚度1.5 μm、AM 1.5G、以及元件未披覆抗反射膜的条件下，短路电流密度可由12.6 mA/cm2提升至13.82 mA/cm2，增加9.7%，而转换效率则可由7.91%提升为8.53%，这结果显示当砷化镓太阳电池基极底部镀有金属反射层时，的确能适度地提升太阳电池的短路电流密度及转换效率。

It was found that both the conversion and the initiating efficiency of methyl methacrylate polymerization system were decreased in the presence of small amounts of addition inhibitions 2,4,6-trinitrophenol or Benzoquinone, the system exhibited some retardation characteristics; at the same time, the molecular weights of obtained polymers was small and the molecular weight distributions was narrow, it was suggested that this polymerization system exhibited some ""living""/controlled radical polymerization characteristics.

The results show that the porosity of the membrane prepared by ScCO_2 induced phase separation is higher than that prepared by conventional method;the membrane structures are significantly influenced by the process parameters;compared with the conventional immersion precipitation phase inversion,ScCO_2 induced phase separation process can effectively avoid the formation of macrovoids at suitable operating conditions;during depressurization process,the great differences in the effect of depressurization time on membranes structure for various polymer materials result from that the speed of CO_2 gaseous nuclei escaping from membrane substrate can not keep the pace with the outer depressurization rate.(2) The tendency that the interaction parameters affect the binodal curve position is illustrated by changing the interaction parameters in reasonable ranges.

研究结果表明：与传统方法相比，采用ScCO_2诱导相转化法可获得更高的膜孔隙率；通过改变操作参数可对膜的结构进行调控，且操作参数对膜结构的影响与铸膜体系的自身性质也紧密相关；在适宜的操作条件下，ScCO_2诱导相转化法能有效避免采用传统的浸入沉淀相转化法制膜时易出现的大空腔结构；泄压过程中CO_2气核从聚合物膜基体中逃逸的速度能否与膜基体外部的泄压速度保持同步，是泄压时间对不同材质膜结构影响截然不同的根源所在。

The electron beam current measured by the beam current monitor (BCT3) is almost in direct proportion to the induced voltage of the fundamental harmonic. When the parameters of the pre-buncher and buncher are adjusted greatly while the beam current being unchanged, the fifth harmonic signal has a great change, but the fundamental signal changes gently. The test results are all in good agreement with the theoretic analysis.

根据不同时刻的记录，基频腔峰值电压与束流流强探测器BCT3所测流强值近似成正比关系；当大幅改变预聚束器和聚束器参数而束流流强不变时，反映聚束质量的五倍频腔信号也随之大幅改变，而反映流强信号的基频腔信号则变化不大，这些试验结果与理论分析完全一致。
