Adding N, P could improve cucumber root activity, increased the absorptionof N, P and Mg, decreased that of K; Adding N improved the contents of Ca,Fe, Mn and Zn in leaves, and adding P accelerated absorption of cucumberroot to Fe. Adding K decreased the contents of N, P in leaves, but increased K,Fe content, contents of Ca, Mn and Zn decreased at the same time.4. Adding the rates and ratio of N, P, and K increased the activity of SOD incucumber leaves and root. The changes of POD activity were complex, maybeP played the more important role.

Although itsapplication in organic synthesis has extented rapidly, a survey of literature showsthat CuCN·2LiCl is almost the only copper salt for the Michael addition reaction offunctionalized organozinc halides, and the amount of CuCN·2LiCl used isstoichiometric. Because of the toxity of CN〓, we try to carry out the reaction inother way instead of CuCN.

但在带官能团的有机卤化锌的Michael加成反应中，到目前为止基本上都是使用毒性较大的铜盐CuCN-2LiCl，为了寻找更好的方法，并使其成为催化反应，我们以带官能团的有机碘化锌的Michael加成反应为目标反应，对FG-R-ZnI在有机合成中的应用进行了考察，得到了较好的结果。

Fluouricil is usually used as anticancer drug, its derivative, 5-fluoro-uracil-1- acetic acid has good biological activity. Its complexes were presented in literatures. However, the coordination modes of it are paradox in literatures. The single crystal structure was resolved to clarify the confusion. The result indicates the carboxylic group coordinates to zinc ion in unidentate, and the heteroatoms of pyrimidine ring are not involved in coordination. Antitumor activity against SMMC-7721 was also examined.

7.5-氟尿嘧啶是临床上广泛使用的抗癌药物，它的衍生物5-氟尿嘧啶-1-乙酸亦具有良好的生物活性，有关它的金属配合物亦有报道，但其结构指认相当混乱，为此研究了它与锌的配合物单晶结构，证明了5-氟尿嘧啶以单齿羧基与锌配位，而嘧啶环氮并未配位，也研究了它对SMMC-7721细胞株的抗肿瘤作用。

The kinetics of reconstitution of apoacylase with either 〓 or 〓 and the inactivation of the 〓 reconstituted enzyme by 1, 10-phenanthroline has been studied by following the substrate reaction continuously in presence of the metal ion or OP respectively. Although the native 〓-containing and the 〓-reconstituted enzymes have closely similar Michaelis constants and maximal velocities, the kinetics for both the inactivation by OP and the reconstitution of the apoenzyme with the metal ions differs considerably.

虽然钴重组的氨基酰化酶与天然含锌的氨基酰化酶在催化活性上比较相近，但两种酶在去金属失活动力学机制以及去金属失活的氨基酰化酶与两种金属离子重组复活的动力学过程均存在较大的差异，说明锌在氨基酰化酶中的作用比较复杂，并不能完全由钴替代。

Reaction of the insertion adducts with epoxide s and α,β unsaturated esters in THF HMPA afforded the corresponding unsymmetrical selenides, respectively.

The effects of metal ions on ethanol tolerance of self-flocculating yeast was studied by using a defined medium in shake flask culture. The observed improvement of zinc ion supplementation on ethanol tolerance promoted the further examination of zinc ion effect on continuous ethanol fermentation. Zinc sulfate was supplemented into the fermentation medium at the concentrations of 0.01, 0.05 and 0.1gL^(-1), respectively.
