Model RWM within the ARSIS concept (Ranchin and Wald 1999) and the P+XS algorithm (Anonymous 1986). A comparison of the synthesised images demonstrates the possible misinterpretation that can result from an non-appropriated method. A quantitative assessment is then performed of the synthesised images. These two comparisons enhance the quality of the method derived from the ARSIS concept.

Result The background noise of bidirectional electrophoresis map of protein extracted by TCAJA method was greater, its clarity was poor, its horizontal striations were more and there were tinny spots with irregular shape appeared on it. The variegated spots had difference from the normal protein spots, they formed high coverage and shading on the other protein spots and affected the accurate expression of map information. The background noise of bidirectional electrophoresis map of protein extracted by Trizol method was little, its horizontal striations and non-protein impurities were less, there was no shading phenomenon strong spots and mere protein spots, so it provided abundant information for quantitative and qualitative analyses on the proteome from buffalo grass seeds, Compared with TCA/A precipitation.

This thesis systematically studies the comparativeness of Chinese trade in services in four aspects of indices basing upon existing achievements by using quantitative analysis method and qualitative analysis method. Moreover, the indices have been compared with those of the five transitional countries in the same timing period. Three points can be drawn from that study. First, the comparativeness of Chinese trade in services are too weak to compete internationally. Secondly, tourism is the only industry that holds its comparative advantage. Finally, we can learn from what the Poland and Hungary have been doing with their trade in services.

This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.

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。
