Japonicus used in this experimentation is matemal inheritance.5 Sequence analysis of mitochondrial 16S rRNA and COI gene and molecular phylogeny of four species of sea cucumber500 bp 16S rRNA and 540 bp COI fragment were obtained by PCR method from mitochondrial DNA of four species of sea cucumber, Apostichopus japonicus, Holothuria fuscogilva, Cucumaria frondosa and Mensamaria intercedens. Variable sites, nucleotide diversity, average number of nucleotide differences and average number of nucleotide substitutions per site were calculated to analyze sequence difference, and phylogenetic trees were constructed by the NJ and ME method.

To determine the true rate of aneuploidy and to elucidate the mechanism of aneuploidy,the sperms were decondensed for FISH analysis. It was found that the disomic frequencies of chromosome X was 0.208%. A new decondensation method was developed by trypsin treatment. The basic morphology of sperm was maintained.

为了解非整倍体的真实发生率及其发生机制，本文以X染色体α卫星DNA探针进一步检测出正常精子中X染色体的二体型频率为0.208％，同时，建立了一种保持精子基本形态的胰酶去凝聚的方法，为目前国内尚未开展的精子遗传物质结构的分子细胞遗传学研究，提供了新的手段。

The structural classes included diterpene, sesquiterpenes, steroids, steroidal glycosides, ceramides and so on.

Subcordiformis in Huanghai Sea near Dalian, it can be able to evolve H〓 photosynthetically. Comparing with Chlamydomonas reinhardtii in our lab, the H〓 productivity is same. By the elementary macro regulation of H〓 production with 2, 5-dibromo-3-methyl-6-isopropyl-p-benzoquinone , N, N'-dicyclohexylcarbodiimide , 3-(3, 4-dichlorophenyl)-1, 1-dimethylurea , sodium dithionate, sulfur-deprivation and cell immobilization, the results show that DCCD, immobilization and sulfur-deprivation has a positive effects on the H〓 production.

利用DCCD（质子泵抑制剂N，N'-dicyclohexylcarbodiimide）、DBMIB（光合电子传递抑制剂2，5-dibromo-3-methyl-6-isopropyl-p-benzoquinone）、DCMU[PSⅡ光合放氧抑制剂3-（3，4-dichlorophenyl）-1，1-dimethylurea]、连二亚硫酸钠、无硫调控及固定化扁藻等手段，对该扁藻产氢进行初步的宏观调控，发现DCCD的加入、扁藻的固定化和无硫调控对产氢均有正效应，其中无硫调控使扁藻产氢时间延长，总产氢量提高了近10倍。

So we adopted the isotope marking method in order to know the distribution of BBP in male and female mice. The result indicated 〓H-BBP presented the first-order kinetics and matched the open two-compartment model. Distributional half-life was about 20 minutes and eliminable half-life was about 6-7 hours. As α(the speed constant of distributional phase) was about ten times β(the speed constant of eliminable phase), this compound had a fast distribution and a low elimination.

为了揭示BBP致毒有明显性别差异的原因，采用同位素标记方法示踪BBP在雄、雌动物体内的归趋，结果表明：BBP在动物体内呈一级动力学线性过程，符合二室开放模型，分布半衰期为20min左右，消除半衰期为6-7hr左右，分布相的速度常数α是消除相的速度常数β的10倍左右，说明该化合物在体内的分布较快、消除慢的特征。

With the guide of non-linear program theory, by using interpolative steps and inexact line search, an improved conjugate gradient method was found, by which the training rate of BP networks increases by tens or hundreds of times. Moreover, the improved method is effective to solve non-linear equations for which Newton's method does not converge owing to the problems of the quadratic derivative and inverse matrix.
