Therefore can pass to use the cupric sulfate sulfuric acid potassium for the catalyst take sulfuric acid as to carry the body to digest it, make the amino acids chelate match the conversion for dissolve sex easily of ammonium sulfate and white vitriol, then absorb a fixed amount to try the kind to join 40% sodium hydroside combine under the steam heat function make ammonia the spirit swims to leave out, through cool off to respond the born boric acid with boric acid, be got the total nitrogen content by the standard aqua titration of hydrochloric acid immediately after;But the white vitriol can immediately join the hydrochloric acid hydroxylate , fluoride to turn the in order to cover up, carry on the titration but get the content of its zinc with the EDTA mark liquid..

因此可以通过用硫酸铜硫酸钾为催化剂以硫酸为载体将其消化，使氨基酸螯合锌转化为易溶性的硫酸铵和硫酸锌，然后吸取一定量的试样加入40 %的氢氧化钠并在水蒸气高温作用下使氨气游离出来，经冷却与硼酸反应生成硼酸铵，接着由盐酸标准溶液滴定得到总氮含量；而硫酸锌即可加入盐酸羟铵、氟化氢铵为掩蔽剂，用EDTA标液进行滴定而得到其锌的含量。

The results are following:(1)We investigated the influence of the positional isomeric effect on structures.Due to the less space-crowding,it is easier for 3-pytpy to behave as bridging ligand than 2-pytpy under the same reaction conditions,while,it is easier for 2-pytpy to function as tridentate chelating ligand to construct supramolecular structures.

研究结果如下：(1)研究了两个吡啶取代三联吡啶配体的位置异构效应对配合物结构的影响。3-pytpy配体比2-pytpy具有更小的空间位阻，在相同的合成条件下容易以单-三齿桥联方式配位；而2-pytpy更易以三齿螯合形式配位，通过π…π堆积作用形成超分子结构。
