The thesis investigated the effect of reation temperation, pH value, and material ratio on the chelating reation. To determine the L-aspartic acid zinc complex\' chelation ratio by orthogonal experiment, we get the best conditions of reaction. On this basis, the thesis synthesized L-aspartic acid autunite complex and L-aspartic acid coppe complex.

A algorithm of dim small targets detection in infrared image is proposed. Image is processed by using median filter and unsharp mask. The infrared image intensity surface is fitted by Haralickd discrete orthogonal polynomial basis function,and then the maximum points are detected on the fitted intensity surface by convolving the image with the second order directional derivative operators.

提出一种红外弱小多目标图像检测方法，图像先经过中值滤波、高提升滤波增强处理，再用基于Haralick离散正交多项式曲面拟合图像，拟合曲面的极大值点即目标点，可以利用导出的二阶方向导数算子与图像进行卷积得到。

The granule was prepared by mixing the water extracts, volatile oil and starch. The content of eucalyptol in the granule was determined with the GC method.ResultsThe optimum extraction condition was as follows: the crude drug was extracted with 10 times amount of water for 5 hours to collect the volatile oil.

In this paper, population genetic variability and genetic structure of five populations of an important cultivation species, mirror carp ( Cyprinus carpio L.) were analyzed using 30 microsatellite loci. The observed and expected heterozygosity values, polymorphic information content and number of effective alleles ( A e were all determined.

采用30个微卫星分子标记，对5个镜鲤群体的观测杂合度、期望杂合度、多态信息含量和有效等位基因数等进行了遗传检测，根据基因频率计算遗传相似系数和Nei氏标准遗传距离，以 c 2检验估计Hardy-Weinberg平衡，以近交系数和基因流分析群体的遗传分化。

It is the bearing rules and common senses having been recognized by human beings for a long time, that only during the ovulation period and after the sexual behavior, can the sperm and ovum can meet and can ovum be fecundated.

人类生育有效性交，是在女性排卵期。只有在女性的排卵期，男女合房性交，男性的精子和女性的卵子才相遇，女性卵子才能受精，这是早已被人类认识了的生育规律和常识。

However, crossing fertility between them was lower than that of mating in and in, and fertilized egg of reciprocal crossing can be incubated and produced F〓 without prezygotic isolation. Among all combinations of reciprocal crossing, crossing of wild male quail×female small-type domestic quail are proved to produce the best effect.

野生日本鸣鹑与家鹑群体之间的杂交能育性低于同种群交配水平，但可以实现正、反交，产生受精卵、孵化出杂种一代，不存在合子前生殖隔离；在所有正、反交组合中，以野雄鹑×小型雌家鹑的效果最好。
