在肿瘤学上，氟化去氧葡萄糖正子电脑断层造影可以有效监测化学治疗和放射线治疗反应。

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.

用四醋酸铅将七元（6-O-二甲基叔丁基硅基）-β-环糊精选择氧化、并用三氟化硼乙醚脱硅基保护基后，再经分离、纯化，可获得具有&楔筒状&空腔的单-2， 3-二醛基-β-环糊精。

Objective In this paper the teratogenic potential of fluoride and methylmercury were studied.
