By properties of a real function, fixed points problem on two complete metric spaces are discussed.The result generalizes corresponding result of Fisher.Moreover, this result provides a general convergence rate estimate. Meanwhile, we discuss the existence of fixed point on two normed linear spaces under the condition of weak topology, and we obtain a new fixed point theorem.

利用实函数性质，讨论了两个不同度量空间中两个映象乘积的不动点问题，推广了Fisher的主要结果，并给了出逼近不动点的敛速估计；同时，在弱拓扑的意义下，利用分析的方法，讨论了赋范空间中有关映象不动点的存在性，得到一个新的不动点定理。

Today's youth may be web-savvy, but they also stand accused of being unread, bad at communicating, socially inept, shameless, dishonest, work-shy, narcissistic and indifferent to the needs of others.

I thank the gods for giving me such a brother, who was able by his moral character to rouse me to vigilance over myself, and who, at the same time, pleased me by his respect and affection; that my children have not been stupid nor deformed in body; that I did not make more proficiency in rhetoric, poetry, and the other studies, in which I should perhaps have been completely engaged, if I had seen that I was making progress in them; that I made haste to place those who brought me up in the station of honour, which they seemed to desire, without putting them off with hope of my doing it some time after, because they were then still young; that I knew Apollonius, Rusticus, Maximus; that I received clear and frequent impressions about living according to nature, and what kind of a life that is, so that, so far as depended on the gods, and their gifts, and help, and inspirations, nothing hindered me from forthwith living according to nature, though I still fall short of it through my own fault, and through not observing the admonitions of the gods, and, I may almost say, their direct instructions; that my body has held out so long in such a kind of life; that I never touched either Benedicta or Theodotus, and that, after having fallen into amatory passions, I was cured; and, though I was often out of humour with Rusticus, I never did anything of which I had occasion to repent; that, though it was my mother's fate to die young, she spent the last years of her life with me; that, whenever I wished to help any man in his need, or on any other occasion, I was never told that I had not the means of doing it; and that to myself the same necessity never happened, to receive anything from another; that I have such a wife, so obedient, and so affectionate, and so simple; that I had abundance of good masters for my children; and that remedies have been shown to me by dreams, both others, and against bloodspitting and giddiness...; and that, when I had an inclination to philosophy, I did not fall into the hands of any sophist, and that I did not waste my time on writers of histories, or in the resolution of syllogisms, or occupy myself about the investigation of appearances in the heavens; for all these things require the help of the gods and fortune.

我感谢神明给了我这样一个兄弟，他能以他的道德品格使我警醒，同时又以他的尊重和柔情使我愉悦；感谢神明使我的孩子既不愚笨又不残废，使我并不熟谙修辞、诗歌和别的学问，假如我看到自己在这些方面取得进展的话，本来有可能完全沉醉于其中的；我感谢神明使我迅速地给予了那些培养我的人以他们看来愿意有的荣誉，而没有延宕他们曾对我寄予的愿我以后这样做的期望（因为他们那时还是年轻的）；我感谢神明使我认识了阿珀洛尼厄斯、拉斯蒂克斯、马克西默斯，这使我对按照自然生活，对那种依赖神灵及他们的恩赐、帮助和灵感而过的生活得到了清晰而巩固的印象，没有什么东西阻止我立即按照自然生活，然而我还是因为自己的过错，因为没有注意到神灵的劝告（我几乎还可以说是他们的直接指示）而没有达到它；我的身体置于这样一种生活之外如此之久，我从未达到本尼迪克特或西奥多图斯的高度，但在陷入情欲之后，我还是被治愈了；虽然我常常达不到拉斯蒂克斯的那种气质，但还是没有做过使我悔恨的事情；虽然我母亲不能尽其天年而终，但她最后的年月是与我在一起的；在我希望帮助任何需要帮助的人的时候，或在任何别的场合，我都不感到我缺乏这样做的手段；而对我自己来说却不会有同样的需要：即需要从别人那里得到的东西；我有一个十分温顺、深情和朴实的妻子；我有许多优秀的教师来教育我的孩子；通过梦和其他办法，我发现各种药物来治疗咯血和头昏……当我有一种对哲学的爱好时，我没有落入任何诡辩家之手，没有在历史作品上，或者在三段论法的解决上浪费时间，也没有专注于探究天国的现象；而上面所有这些事情都要求有神灵和命运的帮助。

Compared with different type male-sterile line found at binucleate microspore stage non-1B/ 1R type male sterile lines and YS type male sterile lines both increase l7kD polypeptide compared with maintainers.

同时通过对比不同类型的不育系发现非1B/1R类K型不育系732A和YS光温敏不育小麦A3017在小穗发育的二核期均多1条分子量大小为17kD的多肽。

At the same time, some defects are pointed out: present fabrics are not properly applied, and most of looms can't produce woven perform whose property is similar in different directions. Their shearing strength are lower, utilization of mechanical properties are also smaller;Although three-dimensional braided composites is of excellent integrated structure, normal braided fiber is traveled from internal to external surface, which is passed through braider and becomes three-dimensional structure. If the external surface is cut or rubbed , it's possible for the fiber to break down. In addition , the shape of perform is easily changed after it's finished . To deal with respective shortcomings and highlight their own advantages, we're searching a new weaving method which is the combination between weaving and braiding .

但它们各自也具有许多缺点：目前机织物适应性不够，大多数织机还不能加工三维各向同性的机制预型件，材料剪切性能较低，力学性能利用率低；三维编织复合材料虽然具有良好的结构整体性，但常用的编织都是纤维从内表面穿到外表面，即穿过编织件的断面成三维结构，用这种方法制成的结构，如果外表面受到摩擦或切割损伤，就有可能导致结构的解体，此外编织结构的织物易变形，所以我们需要考虑一种新的结构，能同时发挥各自优势，又能同时克服二者缺点，这就是机织与编织结构相结合的方法。

The result of stress analysis shows that temperature load induced remarkable thermal stress, and under pressure and temperature load, the distribution of the stress depend on the thermal stress. The most dangerous casse is not the steady operating case, but the transient case at the moment that the shell-side fluid is just shut down, but tube side pressure load and thermal load still retain.

通过强度分析表明，温度载荷对管板造成了较大的热应力，而且在温度载荷及压力载荷共同作用的工况，热应力决定了整个管板系统的应力分布；本题研究的管板的危险工况不是发生在管程载荷、壳程载荷和温度载荷同时作用的正常操作工况下，而是发生在可能出现的壳程压力先停(管程载荷和温度载荷同时作用)的瞬态工况下。

The results were found as following:(1) The damage value increases more significantly with the increase in PVF before 30% PVF, beyond which the increasing trend becomes gradually gentle.(2)Keeping the interphase strength and PVF unchanged, the damage increase with increasing moisture concentration in a nearly linear relation.(3)The results generated from the FCC model with consideration of the interphase debonding are in good agreement with the experimental data, meanwhile, the FCC model is also capable of predicting the critical load for the damaged and the undamaged dental composite subject too the 3-point flexural test.4 A 3D-fmite element analysis has been successfully exploited to examine the mechanical behavior of the restoration-tooth structure under the polymerization shrinkage and water sorption. It was found:(1) The low stiffness of the composite has the effect to limit the displacement occurring in the remaining tooth tissue. For lower interphase, the cuspal flexures are litter higher. The high interphase modulus acts as a \'shielding effect\' for stress transfer.

得到如下结论：(1)相同的吸湿性，在30％PVF(颗粒体积分数：Particle volume fraction，PVF)前增加PVF，层间脱胶损伤值显著增加；此后损伤值的增加趋于平缓；(2)保持层间强度和PVF不变，层间脱胶损伤随吸湿率的增加而接近线性增加；(3)FCC(面心立方：Face-centred cubic，FCC)模型层间脱胶损伤的预测结果和实验数据基本吻合；同时此模型可以用于预测牙齿填充材料三点弯曲实验的临界载荷。4、建立理想牙齿修复结构，利用有限元方法研究了同时考虑聚合收缩和吸湿膨胀耦合作用下的填充修复材料和粘结界面层材料性能对牙齿修复结构的力学行为的影响，得到如下结论：(1)低弹性模量的牙齿填充修复材料能限制天然牙组织的位移，但天然牙组织的位移与粘结界面层的弹性模量无关。

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。
