氟卤气体传感器及其应用

简要说明使用氟卤化合物对臭氧层的破坏,对地球生态环境的影响。为控制和监测大气中氟卤化合物,必须开发和研制氟卤气体传感器。重点介绍了半导体气体氟卤传感器及其应用。

X射线和紫外线激发下BaFCl_xBr_(1-x):Eu^(2+)的发光

制备了ＢａＦＣｌｘＢｒ１－ｘ：Ｅｕ２＋（ｘ＝００，０２，０４，０６，０８，１０）四元系列氟卤化合物．对于不同的Ｃｌ／Ｂｒ比值样品，研究了其在Ｘ射线和紫外线激发下的发光性质；同时研究了在Ｘ射线激发下的发光强度随温度的变化关系，并发现这种关系随Ｃｌ／Ｂｒ比值的变化呈现一定的规律性；最后，测量了在紫外线激发下。

Synthesis of Some More New Fluorinated 1,2,4-triazino[3,4-b][1,3,4]Thiadiazolonesand Their Molluscicidal Against Selective Snails - Part I

Some more new fluorinated 1,2,4-triasino[3,4-b][1,3,4]thiadiazolones （6-9 and 11-16） have been synthesized from cyclocondensation of 5-hydrazino-2-（4＇-fluorophenyl）-1,3,4-thiadiazole with bifunctional oxygen and halogen compounds. Structures of the products have been deduced from their elemental, chemical and spectral data （UV, IIL 1H/13C NMR （nuclear magnetic resonance） and mass）. All the new compounds evaluated as molluscicidal against towards snails which responsible for Bilharziasis diseases.
