合痕类

Our result on the isotopy classes of latin squares of order 7 is also obtained by another mathematics-mechanization method.

我们用另一计算机辅助方法证明，我们所得的7阶拉丁方的564个合痕类代表元是互

AIC improves the procedure determining if two latin squares are isotopy and reduced the complexity of the procedure by a factor of n !

利用方法AIC，本文对7阶拉丁方作了合痕分类，得到了564个合痕类的代表元。

The optimum conditions and the influence factors were investigated, and the composition of ion-association complexes and the reaction mechanism were also discussed. The effects of foreign substances were tested and it is shown that the method has a good selectivity. Based on HgCl2 and basic triphenylmethane dye, the sensitive, simple and rapid method for the determination of trace CTRX was developed.

研究了适宜的反应条件和影响因素，对离子缔合物的组成和离子缔合反应机理进行了探讨，考察了共存物质的影响，表明方法有良好的选择性，据此发展了用HgCl2和碱性三苯甲烷类染料的灵敏、简便、快速测定痕量头孢噻肟钠的新方法。

Studied the coordination chemical reaction of Fe、Co、Ni、Cu、Mg、Ca、Al with TC,OTC,CTC and the ternary association of Co-OTC、Ni-CTC with DAN,we found that the formation of new compounds improved significantly the hydrophilic properties of TCs,the TCs are transformed into hydrophobe from hydrophilic matter.

2研究了Fe、Co、Ni、Cu、Mg、Ca、Al与TC、OTC、CTC之间的配位化学反应和Co-OTC、Ni-CTC与DAN之间的三元缔合作用，发现新化合物的形成显著改善了TC、OTC、CTC的亲水性能，使其由亲水物质转变为疏水物质，有利于提高亲水有机溶剂气浮浮选体系对水样中痕量四环素类抗生素的测定灵敏度和分离/富集效率。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
