简介:在这份报纸,活跃光学和合作焦点,分割的镜子的试验性的系统被造。第一,分割的镜子的支持结构被设计,为分割的镜子的试验性的系统满足要求被模拟验证。在这个系统,大散焦并且倾斜/付小费给分割的镜子的错误被观察密度调整并且基于等斜的干扰理论干扰穗形成对照直到defocus并且倾斜/付小费给错误在Shack-Hartmann的侦探范围。然后,Shack-Hartmann被用来测量他们,他们被致动器调整。致动器被活跃光学控制为分割的镜子的好合作焦点认识到靠近环的调整和维护。并且干扰穗被利用验证Shack-Hartmann的侦探精确。在分割的镜子调整的合作焦点以后,倾斜/付小费给剩余表面错误比RMS好;defocus剩余表面错误比RMS好。

简介:用Co2(CO)8与CH3CSNH2反应制得产物Ⅰ,又用Na2Fe(CO)4与Ⅰ反应制得产物Ⅱ(Ⅰ:Co3(μ3-S)(CO)7(CH3CSNH),Ⅱ:Co2Fe(μ3-S)(CO)7(CH3CSNH).通过元素分析。IR、UV、1HNMR、MS表征并用X射线衍射法测得Ⅱ的单晶结构.该簇合物属三斜晶系、PT空间群,晶胞参数:a=0.9203(1),b=1.1296(2),c=1.1425(2)nm;α=116.40°(2),β=101.92°(2),γ=92.58°(1);z=2,V=1.2162nm3,Dc=1.698cm3,μ=21.89cm-1.结构分析表明,Co2FeS构三角锥分子骨架,所有CO均为端基配体,S1为面桥基配体,CH3CSNH为双齿配体,与Co、Fe形成五元环结构.
