This method allows for a more accurate processing of boundary condition on the semiconductor layer in XLPE cable of stator winding than the standard finite element, so that the interlaminated issue of boundary condition on interface can be avoided. A general algorithm is applied to deal with both the Dirichlet and the periodic boundary condition in 2D or 3D magnetic field problem.
提出了用有限元法计算磁场问题时周期性边界条件和第一类边界条件的统一处理方法,利用该方法在不改变代数方程组阶数、保持系数矩阵性质不变和带宽基本不变的条件下,使两种强加边界条件能同时处理,简化了程序编制,并与寻址方法相结合,提高了计算速度。

Based on the survey of community plots, a quantitative analysis of the communities at Luya Mountain is performed with TWINSPAN Two Way Indicator Species Analysis and DCA Detrended Correspondence Analysis methods. 82 quadrates collected from Luya Mountains were classified into 28 types by TWINSPAN, which belong to seven vegetation types. The result of DCA indicated that those 28 types were reliable. Diagonal line of the two-dimensional ordination diagram of DCA reflects the gradient changes of elevation, temperature and humidity. It is considered that the major factors that restrict the community distribution of the mountains are elevation、temperature and humidity.
本文在群落样方调查基础上,采用双向指示种分析法TWINSPAN和除趋势对应分析DCA对山西芦芽山植物群落进行数量分类和排序TWINSPAN等级分类将芦芽山82个样方分为28类,可归属于7个植被型,分类结果反映了植物群落类型与环境梯度之间的关系,并在 DCA二维排序图上得到较好的验证DCA排序轴对角线基本反映了海拔、温度和湿度的梯度变化,表明群落生境所在地的海拔、温度和湿度是决定群落分布的主要因素

D-Pantothenyl alcohol, also called ortho-vitamin 85, is an important nutrition suppled substance. It has been widely applied in the field such as medicine, cosmetic, foodstuff, feed additive, and so on. The preparation of D-pantothenyl alcohol and the optimization of key factor are discussed mainly in this paper. It mainly includes three section.In the first section, with formaldehyde, isobutyl aldehyde and diethyl oxalate as the starting materials, D-pantolactone is prepared via three steps including condensation, catalytic hydrogenation and physical resolution. The specific rotatory power of the product is consistent with imported product.

The plum-apricot germplasm resources were analyzed by RAPD markers. The results showed that plum-apricot was more close to the related species with low polymorphism. The clustering results were indicated that most plum-apricots were more close to Chinese plum with the similarity of morphological description, thus the female parent for plum-apricot was probably plum in the occurrence naturally. The result of S allele-specific PCR amplification showed that plum-apricot had only one band with the similarity with plum, thus evolution similarity of plum-apricot was more close to plum than apricot.
5对参试杏梅种质资源的RAPD分析表明,杏梅与其近缘种之间亲缘关系较近,多态性相对较少;聚类分析结果显示大部分的杏梅与中国李的遗传距离较近,与形态学上的描述基本一致,因此杏梅种质资源在自然界中产生时,其母本可能为李;同时S等位基因的扩增结果显示杏梅与李的扩增条数一致,都为一条,因此推断杏梅与李的进化趋同性可能较杏更近。

Secondly, it summarizes development and gradual progress about operational risk measurement. Analyzes and compares two main categories at present: bottom-up and top-down, and Loss Distribution Approach of top-down and Income Model of bottom-up is studied deeply, then finds out the main challenges of operational risk measure methods. Thirdly, taking examples for Shanghai Pudong Development Bank and Shenzhen Development Bank, it demonstrates operational risk measurement of our banking using Basic Indicator Approach and Income Model of bottom-up. And by comparing its effects with analysis result of concrete loss incidents of operational risk, it is approved that to apply operational risk measurement to our banking is feasibility. Finally, the paper analyzes difficulties to measure operational risk, such as weak consciousness of measuring operational risk, short of effective modern measuring model, behindhand of loss data collection and lack of perfect inside management mechanism of measurement, and then gives some advices.
