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。

RESULTS: Of 21 eyes with retinal holes, 18 (85.7%) had been sealed and subretinal fluid had been absorbed completely after laser photocoagulation.

随访1～12个月。结果：21只眼经用氩激光治疗后18只眼(85.7%)裂孔完全封闭，视网膜下液吸收。

The associated factors, clinical signs, treatment and prognosis were discussed. Result: Nine patients (6 female and 3 male) were included in this study. All of the patients were associated with myopia, ranging from -0.5 diopters to -5.0D. Gonioscopy revealed a dense homogeneous pigmented band seen over the entire circumference of the trabecular meshwork in all patients; however, no patients with iris transillumination defects were detected. Two of the patients developed pigmentary glaucoma and were treated with β-blocker, miotics and argon laser trabeculoplasty.

结果：九病例中有六位女性及三位男性，所有的病例皆有近视，分布於负零点五至负五点零屈光度，所有的病例在隅角镜检查皆可观察到浓厚的色素沈积在小梁组织，然而在这些病例并没有发现到有典型之虹膜透光缺损：其中有两例后来发展成色素性青光眼，以乙型阻断剂、缩瞳剂和氩氮雷射小梁整形术治疗后，病情控制稳定。
