在一定程度上

In this paper a genetic algorithm four-dimension data assimilation system was applied to the more complex MM5 model, we verify the performance of the genetic algorithm assimilation system, we take the a heavy rainfall process during 04-05, July, 2003 as the experimental research object, and carry out data assimilation experiment of actual observation data, compare the experimental results of the genetic algorithm assimilation system and MM5 adjoint model assimilation system with the experimental results without assimilation, the following is the result:genetic algorithm assimilation system is used not only in a barotropic primitive equation but also in the complex model, MM5, for example, in the ideal experiment the result of the genetic algorithm assimilation system is better than the MM5 adjoint model assimilation system, in the assimilation experiment of actual observation data, whichever assimilation system is used, the initial field of numerical prediction model is effectively improved and the prediction effect of physical field and rainfall are somewhat enhanced.

本文将遗传算法的四维同化系统运用到更复杂的MM5模式中，在理想实验中验证遗传算法同化系统的性能，并以2003年7月4日"南京暴雨"作为研究对象，进行了实际观测资料的同化，并将遗传算法同化系统和MM5伴随模式同化系统得到的结果跟未同化的结果进行了比较，结果如下：遗传算法同化系统不仅可以用在正压原始方程模式上，同样也可以用在MM5等复杂模式上，理想实验证明了遗传算法同化系统优于MM5伴随同化系统，在实际观测资料同化中，采用两种方法的同化系统都能有效地改善数值预报模式的初始场，能在一定程度上提高物理量场和降水量的预报效果。

Species animalcula were isolated from the wounds of Dracaena cochinchinenis stems. During culture period, the culture mediums or the mycelia of four species among the animalcula turned red, which is in some degree similar to the colour of dragon's blood. They were identified as Fusarium graminearum, and another unknown three species of Fusarium.

从剑叶龙血树茎干损伤部位及叶子斑块部位共分离得到24种微生物，其中有4种在培养时候，培养基或菌体本身不同程度的呈现红色，在一定程度上与龙血竭的颜色相类似，经鉴定，它们是Fusarium graminearm和三种未知镰刀菌属真菌Fusarium sp。。

The results show that Tc and diamagnetic susceptivity decrease, crystal structure changes from being orthorhorhombic to a tetragonal system with increasing Fe and Co content.

先将一定的化学组份在一定程度上混和，再热处理得到的一般为颗粒超导体；而在热的（100）SrTiO〓衬底上边溅射边成相能够获得单晶的沿C轴外延的YBaCuO薄膜。

Furthermore, compared with the tautomerizing processes of uracil, the probability of 5-FU to tautomerize to its enol form is much higher. Based on such facts, the reason why 5-FU is an effective anticancer medicament but with some of toxicity is explained to some extent.

通过与尿嘧啶质子转移过程相比较，发现在各种情况下5-氟尿嘧啶异构化为烯醇式的几率均比尿嘧啶的大，在一定程度上解释了为什么5-氟尿嘧啶具有优良抗癌作用的同时具有一定的毒副作用。

Our study leads to the following findings: First, if we take short-term debt into consideration and eliminate the IPO effect, the equity financing preference no longer exists: second, financial deficits play a more important role than traditional firm characteristics in debt ratio adjustment process, which implies that the pecking order theory can account for corporate financing behaviors to some extent: third, equity market conditions and government regulatory policies have some effect on the composition of firm external finance.

基于对中国上市公司股本融资偏好问题的重新审视，我们发现：如果将短期债务考虑在内并剔除首次公开募股的影响，股本融资偏好就不复存在；(2)在企业债务比率的调整过程中，融资缺口所起的作用超过了传统的企业特征因素，这意味着顺序偏好理论能在一定程度上解释企业的融资行为；(3)股票市场状况和政府管制政策会对企业外部融资的构成产生一定的影响。

The distributive characteristics of Sr, Sc, K and REE such as Ce, Y are consist with Ca to some degree. Which means those elements host in Ca〓 sites of francolite. Certainly, other sites of these elements are still exist. It is sug gested that the change of mieroenvironment is the cause of the variation of Mn.

Sr、Sc、K及稀土元素Ce、Y在结核内的分布形式在一定程度上与Ca的位置，当然，它们还有其它赋存形式，Mn的变化可说明了磷结核形成作用过程中微环境发生了一定的变化。

This paper analyzes the employment characteristics of vague language in English business correspondence, and proposes that vague language has a certain kind of indictive function, that is, its employment frequency represents different kinds of business correspondence. It is concluded, through the analysis of the reason, that vague language serves as ostensive stimulus which can he used to make the addresser intention understood by the addressee.

本文从模糊语言在英文商务信函中的使用特点分析着手，提出其在商务信函中具有一定的标识性功能，即模糊语言的使用频率或多或少地反映了商务信函的种类；并对其原因进行分析，得出模糊语言在一定程度上充当明示交际中的明示刺激，在不同的商务信函中被书信人运用来引导收信人对其意图的理解。

本研究结果发现：(1)任务难度对肩部斜方肌活动有显著影响，即随着任务难度的增强，斜方肌振幅指标增强，但平均功率频率和中位频率基本保持不变；(2)时间压力变化对肩部斜方肌活动有显著影响，但在键盘作业中左、右两侧斜方肌肌肉活动变化强度存在差异；(3)心率指标与肌电信号振幅指标AEMG之间存在相当程度的一致性，能在一定程度上反映心理负荷的变化状况，但在低负荷作业中不够。。。

In simulations of pairing afterwards,it can be seenclearly the vorticies amalgamation and coherent characteristic.Compared tothe process of roll-up,the pairing postponed the three-dimensionality to acertain extent.

在随后的涡配对模拟中，由于亚谐波和基波发生共振，相邻两大涡相互作用加强，发生了涡的合并，从结果可以清晰地看到在涡的配对、合并过程流场结构仍保持一定的拟序性，与卷起过程相比，涡的配对在一定程度上延迟了混合层的三维性发展。

The seventh century brought with It a relaxation, not indeed in canonical penance, but in the ecclesiastical control; on the other hand, there was an increase in the number of crimes which demanded a fixed penance if discipline was to be maintained; besides, many hereditary rights of a particular nature, which had led to a certain mitigation of the universal norm of penance, had to be taken into consideration; substitutes and so-called redemptiones, which consisted in pecuniary donations to the poor or to public utilities, gradually gained entrance and vogue; all this necessitated the drawing up of comprehensive lists of the various crimes and of the penances to be imposed for them, so that a certain uniformity among confessors might be reached as to the treatment of penitents and the administration of the sacraments.

第七世纪带来了一个放松，而不是实际上在典型的忏悔，但在教会控制；另一方面，有越来越多的罪行，要求一个固定的忏悔，如果纪律是要保持，而且，许多遗传性权利的特殊性质，这导致了一定缓解的普遍规范的忏悔，不得不加以考虑；替代品和所谓的redemptiones ，其中包括在金钱捐献给穷人或公共事业，逐步入口和时尚；所有这一切，必须制定全面列出的各种罪行和penances强加的，所以在一定程度上的统一性confessors之间可能达成的待遇penitents和管理圣礼。
