In addition, the coordination number of coordination complex formed by phosphorus pentafluoride and aether was calculated and the number decreases from 2.04 to 0.8436 when temperature rises from 0℃ to 30℃; the equation of dissolving rate was also acquired: Y = Bi+2 BiX.

此外还计算了五氟化磷与乙醚形成缔合物的配位数，当T从0℃～30℃时，其值为2.04～0.8436；从试验中得出了不同温度下的溶解速率方程：Y′=B_1+2 B_2X。

Through a single shot experiment powered by a constant voltage charging device,it is found that when discharging in N2,the generator has the same output waveforms for both isolation configurations;but when discharging in SF6,it has a faster rise time for the resistively isolated configuration than that for the inductively isolated configuration,and the reason for this phenomenon was analyzed preliminarily.

通过恒压源充电的单次实验发现，发生器在氮气(N2)中工作时，两种隔离方式的输出脉冲波形基本一致，然而在六氟化硫(SF6)气体中工作时，电感隔离型相对于电阻隔离型的输出脉冲前沿较慢；对其原因做出了初步分析。

The UMG polysilicon can be produced by heating the purified (NH4)2SiF6 above 500℃ in H2/Ar atmosphere. FTIR and XRD results show that amorphous polysilicon granules can be prepared after heat-treatment of (NH4)2SiF6 in a reducing atmosphere. The reduction of silicofluoride salts is a viable method for the production of UMG-Si.

将纯度较高的氟化矽铵盐在氢氩气氛中加热到500℃以上，可制造出冶金级的多晶矽，由XRD、SEM、FTIR与热分析之实验结果显示，在还原气氛中经热处理后所得之粉体为多晶矽，此种方法可以作为制造冶金矽的新方法，进而制备出太阳能产业级的多晶矽。

β-Cyclodextrin with the 6-hydroxyls protected by dimethyl-tert- butylsilyl was selectively oxidized by lead tetraacetate. After the silyl groups were removed off by boron fluoride-etherate, mono-2,3- dialdehydro-β-cyclodextrin as a cuniform molecule could be constructed.
