摘　　要：CaCl_2与PEG（聚乙二醇）在无水乙醇中发生反应而制得的试样，以XPS和IR测试的结果，表明该试样中存在O→Ca配位健。通过溶液电导率的测量，发现1个Ca^2＋与PEG4个链节单元的氧形成配位结构．又以电导率手段测得CuCl2－PAAm（聚丙烯酰按）配位聚合物的配位数，其结果与利用Cu^2＋2pXPS谱上的Shake－up效应研究所得该配位聚合物的配位数一致，间接地验证以电导率手段测得CaCl_2－PEG配位聚合物配位数的可靠性．The coordinatton the of CaCl_2 with PEG was studied by IR and XPS. Formation of coordination compound and the coordination number of CaCl_2-PEG coordination polyme was measured with conductivity method. The conductvity method is a fast and valid method to study the coordination number of CaCl_2-PEG coordination polymer , it was confirmed by conductivity measurement for coordination number and by studied on ESR and shake-up effect of XPS spectra of CaCl_2-PAAm.
