Nuclearization of the family system and alarming increase of divorce, 2 Reduction of the number of children in a family, 3 Rising number of working mothers and womens equal right movement, 4 Lack of opportunity for parents to learn how to raise a child, 5 Steep competition and exclusive emphasis on scholastic achievement in school, 6 Marked changes in value orientations from traditional to modern ones, 7 Confusing and often contradictory advices by "experts" and "professionals" on child rearing and child education, 8 New tides of globalization and confounding co-existence of multi-cultures in most countries and emergences of virtual world, IT and BT industry in some advanced countries, resulting in new forms of psychopathology such as 'internet addiction' and extreme social isolation.Implications of these findings in terms of interventions and prevention for mental health children in developing countries are discussed in developmental, ecological and ethological points of view.

作者提出在大多数亚洲国家存在儿童抚养问题危机，主要依据以下观察：①避孕和意外怀孕②逃避和拒绝抚养，虐待儿童，遗弃幼童③不恰当的早期抚养④不恰当的/不够充分的教育，过度保护和过度控制⑤性别角色和态度改变⑥对智力发展拔苗助长以及学习成绩的压力作者还提出了以下几种现象，它们与亚洲国家的儿童精神健康有着密切关联：①家庭体系核心化和令人担忧的离婚率猛增②家庭成员中儿童数量的减少③职业妇女做母亲及妇女解放运动的兴起④父母亲抚养孩子经验不足⑤学校对学习成绩的过分强调合潜在的竞争压力⑥传统价值观在现代化的冲击中发生明显的变化⑦所谓&专家&和&权威人士&对孩子抚养和教育的观点众说纷纭⑧全球化新潮及多种文化共存的问题，虚拟世界的出现，发达国家IT、BT 工业引发新型精神病理现象如&网络成瘾&和极端的社会隔绝根据这些发现，如何干涉和预防发展中国家的儿童精神健康问题，我们将从精神发育、生物学、行为学观点进行阐述。

It is supposed that tectonic subsidence, eustatic change of sea level and sediment supply rate are the controlling factors of sequence development in marine basins.

The oogenesis and ovary structure during development were studied in Haliotis diversicolor supertexta.

采用组织学方法研究了九孔鲍(Haliotis diversicolor supertexta)的卵子发生、卵巢结构及其发育。

Further study was carried on the cpDNA matK in Hamamelidaceae and its systematic significance (the sequences of matK of some species have been obtained, and the research have been funded by NSFC), and molecular and systematic study were also carried on Magnoliaceae, Rhizophoraceae, Labiatae.

在此基础上，开始了对金缕梅科叶绿体DNA mtK基因及其系统学意义的研究（已测定部分种类的matK基因序列，并获国家自然科学基金国际合作项目的连续资助），同时对木兰科，红树科，唇形科植物类群开展了分子系统发育研究。

Japonica. Brief speculation on the evolutionary trend of the seed-coat micromorphological features of the genus Kadsura is discussed.Cladistic principles and methods have been employed in this study. The morphological characters have been polarized for phylogenetic analysis. Cladograms have been gotten with the related genus Illicium as the outgroup. As a result, a new system of the genus Kadsura has been reconstructed.

整理有关南五味子属植物研究的资料，补充搜集整理近期发表的资料和作者研究所得的数据，采用分支系统学的原理及方法，对本属植物的形态性状进行分析，确定性状极性，以种为基本进化单元，选择近缘且原始的八角属Illicium作为外类群，采用PAUP软件，对本研究得出的性状数据作系统分析，重建南五味子属的系统发育。

Histological analysis showed that the cerebral cortex of Syne DKO and SUN DKO mice displayed severe laminary defects.

组织学分析发现，两种双敲除小鼠的皮层发育严重受损，无法正常分层。

As far as it is known from the history of embryo logy, little was known about the staging and classification of human embryo s until the twentieth century.

就胚胎学的历史而言，在20世纪之前，人们对人类胚胎的发育阶段和分类都知知甚少。

It was studied that the process of the somaticembryogenesis and analyzed that the problem existing in technique of in vitro morphogeny in Hevea to ground for that to probe into the method to improve the technology of tissue culture in Hevea with the techniques of transgene and to improve the ability of somatic embryogenesis and plant percentage of embryoid in Hevea.

本试验以巴西橡胶树，海垦2的花药为外植体，诱导体胚的发生，对体细胞胚发生方式及发育过程做了一系列的组织学观察，分析了橡胶树体细胞胚发生的各个过程以及畸形胚的形成原因，初步结果如下： 1 橡胶花药体细胞胚主要以间接方式发生。

Now, I mainly engaged in myxobacterial genomic and bioinformatics analysis work. Myxobacteria is a single-cell microorganisms, but they act as multi-cell behavior (such as feeding, social movement, cells congregating and fruiting body formation, and so on) and own a wealth of secondary metabolites Product, those remarkable characteristics make myxobacteria important in the research fields of prokaryotes cell differentiation and development, biological evolution, as well as the drug development and research.

现主要从事粘球菌基因组与生物信息学分析方面的研究工作：粘细菌是单细胞微生物，然而却具有多细胞行为（如摄食、社会性运动、细胞聚集和子实体形成等）和丰富的次级代谢产物，这些行为特征使粘细菌在原核生物的细胞分化发育、生物进化以及药物开发研究中占有重要地位。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
