Time series simulations are consistent with sediment records from lake bottom cores back to 100 years ago, and spatial distribution modeling of nutrient resources are agreement with changes in the geographical features. The work suggests that the simulations can catch basic characters of the basin nutrient changes, and provides a powerful tool to evaluate nutrient resources, sedimentations and distributions responding to historical changes in catchment environments.

模拟总氮和总磷浓度与太湖沉积钻孔沉积样推算的水体含量的数量级和变化范围相当，太湖流域的营养盐空间来源模拟也能够与流域自然地理变化吻合，表明模拟能够捕捉到流域营养盐历史变化特征，对湖泊营养物质来源、沉积和空间分布的流域环境历史变化响应具有良好模拟能力。

A category of trunk groups that provides selected services for customer or operators and terminates on announcement systems, switchboards, or desks.

Based on the conservation of miRNAs sequence, we compared the known miRNAs among five mam-mals, i.e., human, mouse, cattle, pig and dog with the sequence of sheep genome that is highly homologous to goat genome, published on the NCBI, and 11 candidate miRNAs were eventually obtained. RT-PCR analysis showed the expression of the 11 miRNAs in brain and 5 in liver, indicating that they might be novel miRNAs. The methodology provides an alternative approach to the exploration of new miRNAs in goat.

根据miRNA分子具有一定的保守性，文章将人、小鼠、牛、猪和狗5种哺乳动物已知的miRNA分子与NCBI公布的与山羊具有极高同源性的绵羊基因组序列对比，获得11条miRNA候选分子，然后通过逆转录聚合酶链反应验证，发现在山羊脑组织中这11条分子均有表达，肝脏组织中有5条分子表达，初步确定为山羊新的miRNA分子，为寻找山羊miRNA提供了新的思路。

Then the boundary element integral equation of interior and exterior form is deduced in detail, also the form with corner coefficient. The significance for numerical calculation and principle of the singular integral is analyzed, and a non-isoparametric transformation method is presented to calculate weak singular integral and Cauchy integral, the method presented provides us a very simple way to computer the two kinds of singular integral of Helmholtz boundary integral equation, and it is easy to program in computer. After the difficulty of the calculation for multi-frequency of Helmholtz boundary element is explained, a method named SECHIEF (Series Expansion Combined Helmholtz Integral Equation Formulation), which is focused on the computational efficiency, is presented.

对结构声辐射的边界积分方程的内部形式与外部形式进行了详细的推导，给出了角点系数的计算方法与边界积分方程的形式，在此基础上，分析了奇异积分产生的原理及其对数值计算的重要性，提出了一种计算奇异积分的非等参(来源：Ae8a8BC论文网www.abclunwen.com)单元的变换方法，该方法给Helmholtz 声学边界积分方程中的弱奇异积分与Cauchy 奇异积分的计算以及编程提供了极大便利。
