QTL with relatively high magnitude of effects might also be involved in epistasis.

F_1、F_2和F_3株高的中亲优势和超亲优势基本上均为负方向，株高优势到了F_2已趋于稳定，且明显低于亲本。

The results showed that fishes of 11 orders, 18 families, and 46 species were represented in Changshu section of the Yangtze river. After the season, the total catch per unit effort increased sharply in the section; the dominant species were mainly commercial fishes such as Coilia ectenes, Mugil cephalus and Parabramis pekinensis and the annual change of dominant species was not obvious. The CPUE of Coilia ectenes had risen up and the trend of resource deterioration had been kept within limits. The caught rate of pintsized and juvenile fish rose markedly. The Margalef's index and Wilhm's index had an evident tendency of rising, while McNaughton's index and Pielou's index waved slightly.

A low level of disturbance can not bring the obvious changes to the subaerial algae in community interior, intermediate disturbance can increase the species quatities of subaerial algae, but can not change the dominant species of algae community, while the serious or repeated disturbance may alter both the component of species and the dominant species, that is species quatities decrease, and dominant species change.

局部小范围的干扰或轻度干扰不会对群落内部亚生藻类的种类组成产生明显影响；中度干扰可使群落内部的亚气生藻类的种类明显增加，但藻类群落的优势种不会改变；而重度干扰下，植物群落内的亚气生藻类的种类组成及优势种均会发生重大变化，种类数量减少，优势种改变。

Results: On dichotic listening task, the schizophrenic patients showed a left ear advantage during the non-forced condition, while the healthy subjects a right ear advantageLI}. An accuracy level of the schizophrenic patients' right ear, however, increased dramatically during the forced-right condition. When attending to the one ear,the schizophrenic patients showed an inability to ignore irrelevant stimuli from the other ear.

结果：两耳分听实验结果显示，非注意条件时，精神分裂症患者为左耳优势，而正常人则表现为右耳优势；精神分裂症患者在注意左耳或右耳时的成绩虽有明显提高，但对另一侧耳信息的抑制能力与正常人相比明显减弱。

However, we don"t find neither the economies of scale nor the diseconomies of scale in the investment banking industry. What"s more, the scope of Chinese investment banks is too narrow and the income relies on the traditional deals too much, which makes the industry far from the economies of scope.The dissertation starts from restrict-pricing model of Spence and Bain-Sylos and analyzes the mechanism of the strategy of excessive production capacity. And based on the extended dynamic game theory of Dixit the dissertation establishes the dynamic game theory model of capital promise and entry deterrence. The dissertationillustrates the essence of scale strategy of Chinese investment banking industry: Firstly domestic investment banks should optimize the capital structure and the scale expansion by proper financing arrangement.

本文对我国投资银行业的产业绩效进行了实证检验：市场结构、行业规模以及市场总体收益率对行业的利润率具有很强的解释能力，从影响的相对水平来看，集中度的影响要大于市场收益的影响，同时，规模的影响与集中度、市场收益的影响相反；同时，基于规模经济的横截面分析表明，我国投资银行业的经济规模与其绩效之间还不存在明显的关系；而且，我国投资银行业总体上经营范围狭窄，业务内涵单一，在收入构成上过分依赖于传统的三大业务，也远远没有发挥出行业的范围经济优势。

Restrictive changes of TCR Vp repertoire and clonal expanded T cells could be found in peripheral blood T cells from patients with T-ALL. However, the clonal expanded T cells' property (clonal expansion leukemic cells or leukemia antigen-specific expansion T cells) should be further characterized. It may play a certain role on detection of minimal residual disease and design of anti-leukemia idiotypic vaccine. The dominant utilization of TCR VjJ repertoire could be found in peripheral blood T cells from patients with B-ALL, meanwhile clonal expansive T cells were existed. It may be a feature of the host immune response for leukemia-associated antigen. The clonal expansive tendency of T cells in V021 and VP23 subfamilies was rather obvious, which may be correlated with certain malignant B-cell clone. The CDR3 sequences of monoclonal expansive T cell in T cell strains were different, which was the base of developing DNA vaccine.

T-ALL患者外周血T细胞的TCR Vβ谱系出现限制性改变，均可检测到克隆性增殖T细胞，尚需进一步鉴定其性质(肿瘤性或抗原特异性增殖)，对于研究微小残留病变检测和设计抗白血病独特型疫苗均有一定的意义。B-ALL病人外周血T细胞的TCR Vβ谱系呈现优势利用的特点，并存在克隆性增殖的T细胞，这可能是机体对白血病相关抗原产生的特异性免疫反应；Vβ21和Vβ23亚家族T细胞发生克隆增殖改变的趋向性比较明显，可能与B-ALL相关抗原刺激有关。T细胞株中检测到的肿瘤克隆其CDR3序列具有高度的特异性，是构建DNA疫苗的基础。

When the number of high accuracy guide stars identified is large, the QUEST algorithm has obvious superiority.According to night-sky observation, based on the guide star flag and the star- Identification information, the selection principle of attitude determination algorithm are given.

四姿态确定算法进行了改进的TRIAD算法和QUEST算法的探讨，这两种定姿算法各有千秋，在识别出的高精度导航星只有2颗的情况下，QUEST算法无法给出姿态，而改进的TRIAD算法可以进行三轴姿态的反演；但在识别出的高精度导航星多的条件下QUEST算法有明显的优势。

Ninety seven spores or sporocarps of VAMF were wet sieved from the rhizosphere soil of mycorrhized pteridophytes, from which 25 VAMF species which belonged to the genera of Acaulospora, Gigaspora, Glomus, Sclerocystis and Scutellospora respectively were identified, and the taxonomic characters of the 25 species were described. The Glomus fungi were the dominant VAMF in the rhizosphere soil of pteridophytes, they took up 44% in the identified 25 VAMF (11 species belong to Glomus); the fungi in Acaulospora and Sclerocystis in the next place, they took up 24% and 16% respectively in the identified VAMF; the fungi in the other genera took up 16%. In terms of the relationships of pteridophytes and the VAMF isolated from their rhizosphere soil, there was no specifity between the VAMF and their host.

从具有VA菌根的蕨类植物对应的根际土壤中用湿筛法筛取了97份VA菌根真菌的孢子或孢子果，从中鉴定出了分属于无醒囊霉属、巨孢囊霉属、球囊霉属、硬囊霉属和盾孢囊霉属的VA菌根真菌25种，并对这25种真菌的分类学特征进行了描述；球囊霉属真菌是蕨类植物根际土壤中的优势类群，已鉴定的25种真菌中，有11种属球囊霉属真菌，占44%，其次是无梗囊霉属和硬囊霉属真菌，分别占24%和16%，其他属的VA菌根真菌占16%，从分离鉴定的蕨类植物根际土壤中的VA菌根真菌与蕨类植物的关系看，VA菌根真菌与蕨类植物之间无明显的专一性。

Using Field single ignition experiments of the four unconfined volume dispersion and small dosage solid FAE and TNT bombs experiments, we got the peak overpressures of solid FAE at different distances. Compared with TNT, The overpressure of FAE is 1.14~1.6 times higher than that of the TNT. Based on the theory of the air shock wave overpressure, the FAE relativity TNT mass is evaluated. At the edge of the explosive field, the number is 3.88. Pictures of high speed photography indicate that the duration and the most effect area of the FAE and TNT. Compared with TNT, obviously the FAE has more advantages. And, based on the theory of the critical concentration of dust explosion, the radius of dust explosive zone is evaluated. The phenomenon that the overpressure decays rapidly with distance is analyzed. It is suggested that the explosive temperature should be increased as the main approach to improve the FAE explosive capability in the condition when the over pressure is invariable.

通过四组无约束固态燃料空气炸药装置与等质量的TNT在野外开放空间的一次起爆对比实验，测得了不同配方组份FAE装置在不同距离的爆炸超压分布，FAE装置峰值超压比相同距离的TNT高1.14-1.6倍；并运用空气冲击波峰值超压公式计算出了FAE的等效爆炸TNT当量随距离的变化关系，在爆炸场边缘区，FAE装置爆炸当量达到了3.88倍TNT当量；通过高速摄影的图片得到了爆炸产生火球的持续时间和最大作用范围，与等质量TNT爆炸火球相比，FAE的优势明显；运用粉尘爆炸下极限浓度估算了云雾爆轰区半径，并分析了测量到的固态FAE爆炸场的压力分布单调衰减的原因；建议在保持超压不变的情况下，把提高爆温作为提高FAE爆炸性能的主要途径。
