Such variations are found that due to applied magnetic field from the substrate . the aspect and brightness of the glow and the self - bias voltage for the target changes significantly . further measurements for the deposited films indicate that the appearance and the deposition rate of the films also vary 一方面，国债的发行促进了我国经济的发展，为经济建设做出了巨大贡献，这方面国债所起的作用是积极的；另方面，国债规模的迅速增加，使政府还本付息的压力越来越大，国债投资对私人投资的“挤出效用”越来越明显。
With mocvd film technology , film chemical composition is easier to control , deposition temperature lower , deposition speed higher , deposited film more compact , homogenous and flat . in this paper , firstly , the study of fgms , the study of cvd and mocvd , and the nucleation mechanism have been introduced . secondly , the fabracations of metal / metal and metal / ceramic fgms have been reported 本文在介绍功能梯度材料的研究进展， cvd 、 mocvd技术的研究概况以及mo ( co ) _ 6 ， fe ( co ) _ 5的成膜机制和工艺条件之后，着重报道了利用mocvd技术制备陶瓷薄膜，金属金属和金属陶瓷功能梯度材料。
