The title complexes [Dy(p-NBA)3Phen]2·3H2O(I) and [Dy(m-NBA)3Phen]2·4H2O(Ⅱ) were synthesized, in the two molecular formulas of which NBA is nitrobenzoate and Phen is 1,10-phenanthroline. The characterizations of the complexes were carried out by means of elemental analysis, UV, IR, XRD and molar conductivity. The thermal decomposition of the two complexes were studied under the non-isothermal condition by DSC, TG-DTG and IR methods in detail. The kinetic parameters of the dehydration process were also obtained by the analysis of DSC curves of the two complexes with Popescu and Vyazovkin methods, respectively, The title complexes [Dy (p-NBA) 3Phen] 2 .3H2O (I) and [Dy (m-NBA) 3Phen] 2.4H2O (II) were synthesized, in the two molecular formulas of which NBA is nitrobenzoate and Phen is The characterizations of the complexes were carried out by means of elemental analysis, UV, IR, XRD and molar conductivity.

土壤盐碱化一直是制约河套灌区农业生产发展的主要障碍因素。灌区节水改造工程实施后 ,土壤盐碱化是否会进一步恶化 ?灌区合理的排灌比应该是多少 ?一直是人们所担心的问题。
年前,免职后的原教育部副部长张保庆大胆放言:“中国目前最大的问题是政令不通,中南海制定的东西有时都出不了中南海。”此言一出,立马引发了传媒的轰动效应。句中的勇于自揭疮疤、敢讲实话精神,引来一片叫好声。  笔者在忆及叫好之余忽然想到,中央政令有时“出不了中南海”,其实只是形象之语。“中南海”是什么地方?那是中国共产党和政府的最高司令部,在中南海内有谁会阻挡中央政令下传?有谁敢、有谁能阻挡中央政令下传
