The paper firstly examined the mechanical characteristics of wood samples at micron scale, which provided some theoretical basis for the application of wood microtome section to study the in-tree variation of longitudinal mechanical properties of tracheids. In chapter 3, microtension of wood microtome section is for the first time used to explore the in-tree variation of longitudinal MOE of tracheids, meanwhile the size effect of mechanical properties of wood at micron scale is taken into count.

本项研究正是基于以上考虑而提出的，首要目标是提出能快速评价管胞纵向力学性质的实验技术，并以此研究了人工林杉木管胞纵向力学性能的株内变异规律；目的之二是从实验和理论的角度研究管胞细胞壁力学性质的主要影响因素，为树木木材品质的基因改良提供量化的目标和指标。

In D3 gene with 5 site mutations. There exists individual variation in the COII gene, but this variation is less than that among other members of Myzomyia Series such as An. aconitus, An. jeyporiensis, etc. In addition, one haplotype different from both An. minimus A and C was found in these 3 genes studied.②The genetic distance between An. minimus A and An. minimus C is less than that among other members of Myzomyia Series. Molecular trees based on different genes and different methods show that An.

种系发生研究表明，微小按蚊复合体亲缘种A、C间的遗传距离远小于与之近缘的同系其它成员间的距离。2个分子标记3种方法构建的基因树显示，微小按蚊A、C的种系地位非常固定，不同地域来源、不同变异类型的微小按蚊始终在同一分"枝"上，与迈蚊系其它成员相比，呈现其相对稳固的单源性。

It is a nice irony, given the traditional association of the naturist position with eugenic arguments, that if variation in intelligence really is caused by underlying genetic variation, then the dull are as evolutionarily fit as the clever.

这是对那些还在对优生争论的自然主义的传统协会的一个美妙的讽刺。他们一直在争论在如果智力上的变化真的是由潜在的基因变异引起的，那么低能儿是否能和高能儿一样适应进化。

The result indicates that:(1) the coefficients of variation of all strains' quality character are different, so it is effective to select qualitative character from the descendants;(2) the content of fat and content of water-soluble protein are remarkably negative correlation among variation strains.

结果表明：(1)所有品系的品质性状的变异系数差别较大，说明在后代中进行品质性状筛选是有效的；(2)突变品系内脂肪含量与水溶性蛋白含量呈显著负相关。

These differences may be of evolutionary significance because additive variation responds quickly to selection, whereas nonadditive genetic variation does not.

雄性获得的好的特征会得到促进，坏的会遭到删除；而对于雌性来说，好坏特征可以并存，只不过有害特征没有表达而已。

The south and north of the windward side of the Annam Cordillera show great difference in the diurnal variation of rainfall, which is related to migration of rainfall. Rainfall over coastal areas of the Thailand Gulf in 01-04LST migrates to inland northeastwards and then heavy rainfall occurs over areas southwest of the Annam Cordillera in 16-19LST, after that heavy rainfall migrates northwestward along the Annam Cordillera to areas northwest of the Annam Cordillera in 01-04LST in the next day. The migration of rainfall results in different characteristics of diurnal variation on the windward side of Annam Cordillera.

长山山脉西侧迎风坡的一南一北两个区域，表现出明显不同的降水日变化特征，其原因与降水的传播有关。01-04LST，降水大值区出现在泰国湾东部沿海，并向中南半岛岛内传播，16-19LST在长山山脉西南侧形成降水大值区，之后降水进一步沿山脉向西北传播，并于次日01-04LST传到长山山脉西北侧区域，通过降水的这种传播特征从而导致长山山脉迎风坡一侧不同的降水日变化特征。

The results showed that the number of chromosome, which was from the cultured seedlings of meristem tip and the rank seedlings of meristem tip, was not altered, both the number were 2n=16,the hereditary stability of callus and regeneration plant was poor; and the variation percentage of chromosome in callus was 43.4%, among which haploid accounted for 6.7%, triploid accounted for 2.5%,tetraploid accounted for 10%,pentaploid accounted for 4.2%,hexaploid accounted for 3.3%,septuploid accounted for 4.2%,octoploid accounted for 3.3%,dysploid accounted for 9.2%;the chromosome variation percentage of differentiation seedlings derived from callus was11.7%,among which haploid was 6.7%,triploid accounted for 1.7%,tetraploid was 3.3%.

结果表明，茎尖分生组织培养的幼苗及丛生苗遗传稳定，其染色体未发生倍性变异，均为2n=16；愈伤组织及其再生苗遗传稳定性较差，愈伤组织染色体数变异率为43.4%，其中单倍体占6.7%、三倍体占2.5%、四倍体占10%、五倍体占4.2%、六倍体占3.3%、七倍体占4.2%、八倍体占3.3%、非整倍体占9.2%；愈伤组织分化苗染色体变异率为11.7%，其中单倍体占6.7%，三倍体占1.7%，四倍体占3.3%。
