The carbon compounds sink in the pondwater and seep underground where bacteria digest them, setting up the perfect chemical conditions to free up the soil's arsenic.

碳元素在池水中沉降并渗入地下，在那里他们被微生物分解，为土壤中砷的释放提供了绝佳的化学反应条件。

For example, thevast majority of very tall buildings in the world have Oleobuffers at the bottom of their lift shafts (which is good to know,if ever I'm in a lift free-falling 80 storeys).

比如，世界上绝大多数高层建筑都会在电梯轴底部使用Oleo的缓冲器（如果我乘坐的电梯从80层掉下来，知道这点很有帮助）。

Mutation rate at exon of GH in five bovine species was very low with the percentage of 3.48%. The majority of nucleotide substitution was nonsense mutation and only one missense mutation was observed. Molecule tree based on haplotypes of bGH at exon 5 showed that differentiation was apparent relatively between Bubalus bubalis and Bos taurus, Bos indicus, Bos grunniens, Bos frontalis. There was no apparent differentiation among other four bovine species and they shared mutual ancestral sequence.

序列分析表明，5个牛种GH基因外显子5的遗传变异水平较低，平均核苷酸变异率约为3.48%，而且绝大多数位点的核苷酸替换是同义突变，仅发现1个错义突变位点；从GH基因外显子5序列单倍型构建的分子进化树来看，水牛与普通牛、瘤牛、牦牛及大额牛的分化相对比较明显，其他4个牛种之间并无明显分化，还享有共同的祖先序列。

The character of heating distribution near the front and the action of diabetic heating frontogenesis on the frontal maintenance and movement are estimated by using the objective data.

The evolution of frontal rainbands happening during the frontogenesis induced by deformation field is investigated through the numerical cloud model. Besides, in order to get insight from the results of numerical simulations, the semigeostrophic frontogenesis model is used to investigate the effect of diabatic heating on the frontogenesis and the analytical method of WKBJ is used to study the influence of large-scale deformation field and frontal circulation on the development of symmetric disturbance happened in the frontal zone.

为了加深对数值模拟结果的理解，还利用半地转模式对非绝热加热影响锋生的过程进行了讨论，通过WKBJ方法讨论了变形场锋生条件下对称扰动的发展，从中可以了解大尺度变形场和锋生环流对中尺度扰动的作用，这方面的工作可以对前面非静力数值模拟结果的理解提供帮助。

The frontogenesis process involves in the interactions among the systems of multiple scales. Since the hardness of the nonlinear problem, it is difficult to study frontogenesis analytically. The introduction of the effects of orography, friction and diabatic processes generally makes impossible the analytical resolution of the problem and leads to the use of numerical models. Primitive equations are numerical integrated together with a detailed description of physical processes. The circulation obtained is then used to diagnose and test theoretical mechanisms. It should be noted, however, that a fully description of frontogenesis in explicitly resolving the of large-, meso- and micro-scale flow in the same framework is not yet possible because of the excessive computer capacity and the time required. In order to deal with the problem, the action of large-scale background has been simplified and taken into consideration through the addition of the forcing into the nonhydrostatic cloud model.

大气锋生是一种多尺度相互作用的过程，理论研究遇到非线性的困难，在考虑地形、摩擦、非绝热等物理过程之后，解析研究更加棘手，通过数值模拟搞清其中的物理机制是重要的研究手段，但是把大、中、小尺度甚至微尺度的系统及其相互作用过程在一个模式里同时模拟好仍然受计算机速度和容量的限制，本论文在非静力云模式中通过强迫方式加入大尺度变形场的作用，在考虑到大尺度背景作用的同时，可以充分利用云模式所提供的丰富物理过程、非静力和高分辨率特点，开展一些过去较难进行的研究工作。

This doctoral dissertation is composed of several parts: At beginning, the frontal structure, the effects of diabatic heating and orography, the dynamics of frontal circulation and the mesoscale systems associated with front are reviewed. Several problems based on the review are brought forward. First, at present, the semigeostrophic frontogenesis theory is the most appropriate basic framework for the general explanation of the frontogenetic process. However, the comparison between semigeostrophic theory and the observation have revealed some inconsistencies. The newly observational facts increase the inconsistencies.

本博士论文主要由如下几部分组成，首先对锋面结构、地形和非绝热加热对锋的影响、锋生环流及锋面附近中尺度系统动力学问题的历史与现状进行了综述，在此基础上提出需要进行研究的若干问题：(1)、半地转锋生理论直到今天仍是解释锋生过程的最合适的理论框架，但是通过与观测事实比较，人们发现半地转理论不能对许多锋面观测特征给出令人满意的回答，新的观测事实使问题更加突出，这就向人们提出：是什么原因导致半地转理论与实际观测的不符？
