研究发现，碰撞电离总截面随等离子屏蔽的增加而增大，特别是在10 keV/u以下的低能区电离截面有量级的增加。对随能量变化的一阶微分截面，在低能碰撞过程中，屏蔽作用增加，微分截面呈量级增加，高能碰撞微分截面呈倍数增加。

The higher percentage of cross-fertilized kernel specifically expressed pattern was observed in highly heterotic hybrid, after comparison of gene differential expression between cross-fertilized and self-fertilized kernels during the early development of seed in wheat and maize, respectively. This indicated that there may be have common molecular mechanism for heterosis in different crops.

本文对玉米和小麦在种子发育前期杂交和自交间基因差异表达进行了比较，发现杂交特异表达类型与杂种优势均存在一定的正向关系，说明不同作物杂种优势形成在分子水平上具有共同点，即相同表达模式的基因或基因群在不同作物杂种优势形成中发挥一致的作用。

In order to understand the molecular basis of heterosis, modified differential display of mRNA was used to characterize the difference in gene expression between cross-fertilized and self-fertilized kernels, reciprocal cross-fertilized kernels and their parents during the early stages of seed development by using 3 wheat hybrids with different level of heterosis.

The ABSOLUTE directive can be thought of as an alternative form of SECTION: it causes the subsequent code to be directed at no physical section, but at the hypothetical section starting at the given absolute address.

ABSOLUTE操作符可以被认为是SECTION的另一种形式：它会让接下来的代码不对准任何的物理段，而是在一个从给定的绝对地址开始的假想段中。

This chapter is divided into three sections, section I, as a "Creative intention of practical", which runs through the Qing Dynasty,"Lao Zi" annotation in the face of "Dao De Jing", and to explore the practical in the point of view of social values; The second section as "The study of the inherit in the relationship between Confucius and Lao Zi", explain that the Qing Dynasty "Dao De Jing" annotator since the Song and Ming inherited "The merge of Confucianism and Taoism" concept, from the clarification of the relationship between the Confucianism and Taoism to of sure the value of "Dao De Jing"; the third section for the "Merger of three religions and integration of China and Western Academic" explain the harmonization is the characteristics of Chinese culture.

本章共分为四节，第一节为「经世致用的创作意图」，由此贯串清代《老子》注家在面对《老子》一书的主要面向，以入世、实用的角度发掘老子的社会价值；第二节为「孔老关系的承袭论述」，说明清代《老子》注家承袭宋明以来「孔老会通」的观念，由儒、老之间关系的厘清与定位，肯定《老子》一书的价值；第三节为「佛老思想的交融互释」，突显此时以佛解老的注作大多依附於三教思想的汇流之中；第四节为「三教融合与中西会通」，说明融通是中国文化的特色，在三教融合的思想承继之上，此时的知识份子在西方武力与文化的侵略之下，开始以西学为参照，探寻《老子》的现代化意涵。

This chapter is divided into three sections, section I, for the analysis of "Lao Zi" annotator in Qing Dynasty in the impact of three religions, it was agreed that "eliminate emotion and regress to humanity" idea. Section II to illustrate mainly the traditional "Lao Zi" annotation in Qing Dynasty, the impact in Western countries began to accept the idea of Western Ideas, output the first "Lao Zi" annotation base on Western Ideas –Yan Fu "Ping Dian Lao Zi"; Section III of "freedom, democracy, equality", to discuss Yan Fu think "Lao Zi" already have many of the modern social values:"free","equality","teamwork".

本章共分为三节，第一节为「复性化情」，析论清代《老子》注家在三教思想的濡染下，一致提出「复性化情」的主张，作为体道、得道的路径；第二节为「会通之道」，说明以传统守成态度为主的清代《老子》注，在西方国家的冲击下，开始接纳西学的理念，开出了第一本以西学解老的著作──严复《评点老子》，此书反映了他中西学术兼容并蓄的思想，他不仅融合儒、释、道的概念，更将西方的科学、哲学纳入《老子》的思考当中；第三节为「自由、民主、平等」，旨在讨论严复认为老子书中已经具备许多近现代的社会价值：「自由」、「平等」「合群」的概念。

Objective:to investigate the cesarean section of the reasons for the bleeding, and lower the rate of obstetric hysterectomy possibility.methods: 30 cases in our hospital cesarean section in the clinical data of patients with hemorrhage were retrospectively analyzed.results: in 30 cases of bleeding, placental factors accounted for 53.33%, 36.67% of the uterine atony, uterine incision bleeding laceration of 6.67%, 3.33% of the amniotic fluid embolism, hysterectomy three cases.conclusion:placenta, uterine atony cesarean section is the main reason for the bleeding.

目的：探讨剖宫产术中大出血的原因及降低产科子宫切除率的可能性。方法：对我院30例剖宫产术中大出血患者的临床资料进行回顾性分析。结果：30例大出血中，胎盘因素占53.33%，宫缩乏力占36.67%，子宫切口裂伤出血占6.67%，羊水栓塞占3.33%。治疗结果中，子宫切除3例，占剖宫产术的0.076%（3/3 935）。结论：胎盘因素、宫缩乏力是剖宫产术中大出血的主要原因。

The comprehensive treatment project of Tong Ken landslide consists of whittling slope、anti-landslide pile with anchoring cable、retaining wall、building ground drainages leveling off and calking slope、vegetation protection etc. After managing, under the action of earthquake load and watery the stability coefficient of landslide is up to 1.10.Then, this text researches the structural optimization design of anti-slide pile with anchoring cable. On the condition that the width of section is invariable, the height of section is confirmed by structural optimization method. This will change traditional method to optimize the height of section so that design is simplified and cost is lower.
