主要讨论了如何使ＶＧ－ｑｕａｔｔｒｏ四极质谱仪微机磁盘操作系统（ＤＯＳ）升级、如何充分利用各种分析仪器所配微机系统资源及如何多重配置微机系统给出了相应的配置文件。

VG-quattro四极质谱仪计算机硬盘机的升级

对VG-quattro四极质谱仪计算机的硬盘机进行了升级改造,用IDE接口取代了原ST506/412接口,从而可以安装3.5英寸420MB硬盘。介绍了IDE接口,IDE接口卡的配置,硬盘类型参数的设置及硬盘的逻辑安装。

VG-Quattro四极质谱系统软件的备份及恢复

以VG-Quattro四极质谱仪微机系统软件为例,讨论了有关系统文件备份的几种方法及其优缺点。

DEHYDROGENATION OF ORGANOLANTHANIDE ALKOXIDES AND X-RAY CRYSTAL-STRUCTURE OF REACTION-PRODUCT [(C5H-5)2YB(MU-OCH=C=CH2)]2

[Cp3Yb] reacts with HOR (Cp = C5H5; R = CH2CH=CH2, CH2CH2Me) in thf (thf = tetrahydrofuran)at room temperature to give complexes [{Cp2Yb(mu-OR)}2], which are dehydrogenated to yield the new complex [{Cp2Yb(mu-OCH=C=CH2)}2] in refluxing thf solution; the X-ray crystal structure shows that the new complex is dimeric with oxygen atoms as bridging groups.
