The dynamic structure of Mo-O species in Ag-Mo-P-O catalyst was studied by in situ confocal microprobe laser Raman spectroscopy (LRS) and catalytic test. The results indicate Mo-O species of MoO3 transformed to Mo-O species of AgMoO2PO4 in C3H8/O2/N2 (3/1/4) flow at 773 K. This behavior is closely relative to oxidative dehydrogenation of propane and intrinsic properties of Mo-O species. The Mo-O species of AgMoO2PO4 may be active species for oxidative dehydrogenation of propane.

摘 要:近年来,会计电算化的发展朝更深层次迈进,给企业带来了巨大的经济效益,但是同学也给企业的内部控制提出了更高的要求。企业实施会计电算化改变了企业的会计管理环境,在处理速度加快的同时,给会计管理的准确性和可靠性带来了挑战。本文针对会计电算化视角下的企业内部控制进行了探析。  关键词:会计电算化;内控制度;对策  与古老的会计核准方式相比,电算化背景下的新型会计管理方式使得数据处理的速度加快,在
