ABSTRACT It is because that the excellent acceptors for maize transgenic engineering are insufficient in our country, especially in the southwest mountain areas of china and hereditary variation regularity for the two characters such as efficiency of embryonic callus induction and number of regenerating plant (these two characters were abbreviated to the nduction efficiency and number of regenerating in the following of the paper, respectively), which hint the maize culturing capacity, is not very clear. Therefore, aiming at picking out superior acceptors, we had made systematic researches on the two characters with combing traditional quantitative-character genetic analyzing methods such as single-factor genetic mating design, diallel crossing genetic design, genetic effect analyzing method and the modern molecular locating method such as QTLs'. The main results are followed.(1) 50 superior inbred lines and about 30 crosses in our country, especially in the southwest of China were used for identifying and selecting the superior genotypes in the above two investigated characters under the same culturing condition in 2000 and 2001. There was very significant difference among the genotypes in the both characters. But the two characters were not certainly related. Some genotypes such as 18-599 and 18-599 were very good in them. For some ones such as zong 31, induction was higher than 18-599 and 18-599 in the efficiency, but it was only 1/3 to the later in regenerating number. In some genotypes such as S37, R08, R15, P138, A318, induction efficiency was just about 3% and scarcely any regenerating plants were got. On the whole, hybrids acted better than inbreeds in the both characters.(2) Two kind of inbreeds were selected as parents of the Griffing's method 1. 18-599 and 18-599 and the inbred line zong 31 are one kind because they are not only superior in the characters of maize cross breeding, such as CA, resistance to disease and the important agricultural characters, but also excellent in transformation characters as the induction and regeneration.
针对我国、特别是西南山地所需玉米转基因工程育种优良受体极为匮乏和反应玉米幼胚培养能力的2个主要性状,即玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数的遗传变异规律十分不清楚的实际情况,本研究从筛选玉米转基因工程所需要的优良受体入手,采用单因素遗传交配设计、双列杂交遗传交配设计、世代基因效应等传统数量性状分析方法,以及现代分子标记定位主效QTL分析方法,对玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个性状进行了较为系统的分析研究,取得以下主要研究结果:(1)于2000年和2001年通过对我国、特别是西南地区近50份优良自交系和近30个杂交组合,在相同培养条件下,对幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个幼胚培养能力性状进行了筛选与鉴定,发现玉米不同基因型具有完全不同的幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数,但幼胚培养胚性愈伤组织诱导率与胚性愈伤组织绿苗发生数并不具有必然的相关关系,有的基因型,如自交系18-599和18-599在胚性愈伤组织诱导率和愈伤组织绿苗发生数等2个性状都表现相当优异;有的基因型,如自交系综31,仅幼胚培养胚性愈伤组织诱导率性状表现高于19-599和18-599,但在胚性愈伤组织绿苗发生数这一性状则与它们有相当大的差距,仅为19-599和18-599的1/3左右;有的基因型,如S37、R08、R15、P138、A318等玉米自交系不仅幼胚培养胚性愈伤组织诱导率很低,平均仅在3%左右,而且胚性愈伤组织绿苗发生数表现也很差,基本上没有分化成苗。

Textbook is not only the primary basis for students to grasp knowledge and method but also resort and carrier to train capability. New textbook has been tested in some provinces and cities since 1997, some educational and teaching concepts in new textbook inosculates with new mathematics course which is being tested now, it has taken great role for the transition of teachers' teaching idea and students' learning way. This paper will analyze Plane Analytic Geometry high school textbook of 2004 edition which is published by People's Education Publishing House in some aspects such as content structure, educational function, psychological characteristic according with student cognizance and teaching through the method of content analysis, investigation, comparison and statistical analysis . The paper's purpose is to excavate the potential value of the textbook and understand educational idea and concept of new textbook so that students can grasp more basic thought of analytic geometry in teaching and can learn studying and discovering and solving problem ,at the same time it builds a kind of independent, disquisitive, cooperative and lifelong learning pattern.
教材既是学生掌握知识和方法的主要依据,又是培养学生能力的凭借和载体,自1997年新教材在部分省市实验以来,新教材中所体现的一些教育教学理念与现在正在实验的高中数学新课程相吻合,对教师的教学观念和学生的学习方式的转变都起到了很大的作用,本文将对人民教育出版社2004版普通高中教材中的平面解析几何部分通过内容分析法、调查研究、比较研究、统计分析等研究方法从教材的内容结构、教育功能、符合学生认知心理特点、教学等几个方面进行分析,目的是挖掘教材内容的潜在价值,真正领会新教材所蕴涵的教育思想和理念,以使教师在教学中能够让学生更多的掌握解析几何的基本思想,以培养学生学会学习、学会发现问题和解决问题,为学生构建一种自主的、探究的、合作的、终身的学习模式。

No doubt Stephen had by his language given some grounds for the accusation; his accusers apparently twisted into the offensive utterance attributed to him a declaration that "the most High dwelleth not in houses made by hands"(vii, 48), some mention of Jesus foretelling the destruction of the Temple and some inveighing against the burthensome traditions fencing about the Law, or rather the asseveration so often repeated by the Apostles that "there is no salvation in any other" cf.
毫无疑问,斯蒂芬曾由他的语言给出了一些理由的指责,他的指控显然是歪曲为攻击性话语归功於他的声明,表示&最高级从永远不要在房子所作的手&(第七章, 48条),有些提及耶稣预言摧毁庙宇和一些inveighing对burthensome传统击剑有关法律,或者更确切地说,该asseveration所以经常反复,由传道者说:&绝对不存在救赎,在任何其他&(参见四, 12 )法律没有排除,但耶稣。

Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.
因此本章会先就父子关系的冲突与矛盾做深入的探讨,小说中的父亲似有对儿子爱之深责之切的行为,其原因可能在於父亲将儿子视为所有物所致;其次,论文将引用拉冈相关理论,讨论在父权社会中,不论身分为何,只要是已受父权社会观念根深蒂固影响的人物,终生都将受其所苦,此也揭示出人生存於社会上的无奈。
