摘　　要： 多相催化反应通常是在高温和一定的气氛中活化及反应,粉末X-射线衍射仪一般均在室温和空气气氛下操作,不能获得反应条件下催化剂的物相变化数据,对正确阐明反应机理和催化作用机制有一定的困难.我们从催化剂及动力学研究的需要出发,参照有关文献,与北京大学仪器厂合作设计,并由后者制造了一台原位X-射线衍射反应器,经初步试验获得了满意的效果.本文着重介绍原位反应器的结构及初步试验的结果。 In this paper a chamber-reactor that makes it possible to investigate the kineties of catalytic reaction with simultaneous X-ray diffraction phase analysis of the catalyst during the reaction is described. Two samples, the phase trasformations of quartz pow-der during temperature variation and the reduction of CuO with H_2 were investigatedby this chamber reactor. An analysis of XRD spectrum leads to the conclusion thatuse of a Beryllium window have some special advantages.
