Part three : it analyses the relationship among accumulative cost effect , financial risk and bubble economy . long position mechanism of our country causes accumulative cost effect . when accumulating to a certain extent , it will result in 由于我国单边做多机制产生累积成本效应，而当累积成本效应达到一定程度时，就会引发金融危机，这种由累积成本效应所导致的风险有其自身的特征，而且如果控制不好，会使风险进一步扩散，形成泡沫经济。
They are the chief means of liberating agriculture from its chains , and of elevating it to a commercial character and to a degree of art and science , by which the rents , farming profits , and wages are increased , and greater value is given to landed property 要把农业从束缚中解放出来，要从农业提高到商业阶段，在技术和科学上达到一定程度的水平，从而使地租、农业的收入与工资都有所增长，使地产价值提高? ?要达到这样的目的，工业是一个主要手段。
In the modern society , regardless of the physical product , the economical commercial activity , or basic necessities of life , are about " packaging " , " design " , the design has been involved in all aspects of society , the images of enterprise ' s websites are designed and arisen at the historic moment too , can be said to be the extension of the enterprise cis strategies in the network 现代社会,无论是物质产品,还是经济商业活动,抑或是衣食住行,都很讲究“包装” 、 “设计” ,设计已经涉及社会的方方面面,企业网站的形象设计也应运而生,可以说是企业cis战略在网络上的延伸。当物质文明达到一定程度,人们便不再仅仅满足于丰衣足食。
During deformation they are usually time and stress - dependent . when loads are high , their deformation may be nonlinear . in order to describe the mechanical behavior of nonlinear viscoelastic material accurately , the effect of damage must be considered in the constitutive equation 高聚物是典型的粘弹性材料，在变形过程中通常呈现出强烈的时间和应力敏感性，当载荷水平达到一定程度时会出现非线性变形，为精确描述非线性粘弹性材料的力学行为，必须考虑损伤对材料本构关系的影响。
Is it dam in particle , filter screen of inboard becoming certain to act as , cause imports and exports end pigeonhole difference is it get keep difference at the difference of pigeonholing controller set for to increase , start back flush , after back flush , press difference and return to normal , the filter resumes to filtering the working state normally again 当被截流在滤网内侧的颗粒达到一定程度，致使进出口端的压差增大到压差控制器所设定的压差值时，开始进行反冲洗，通过反冲洗后，压差恢复正常，过滤器又恢复到正常过滤工作状态。
For the same configuration resonance chamber , the intensity of the self - oscillation is changed by the waterpower parameters . when the pressure increases , self - oscillation intensity will increase . by applying the self - oscillation generated by the resonance chamber to the heat exchanger , and when the self - oscillation intensity achieves a certain degree , heat transfer will be enhanced 对于同一结构的共振腔，水力参数不同，产生的自激振荡强弱也不相同，随着压力的增加，自激振荡的强度也增加；将共振腔产生的自激振荡引入换热器后，当自激振荡达到一定程度的强度后，可以强化换热。
The study of phase formation of the polycrystalline la1 - xagxmno a series of polycrystalline la1 - xagxmno3 samples with x range nominally from 0 . 05 to 0 . 45 were investigated , and found that the critical phase temperature has close relation with the content of silver in the sample . and pointed out in the case of agl + doped in lamno3 , when x achieved a fixed value ( x = 0 . 15 ) , ag would separate out , ag - rich phase appeared , samples became compound phase 并且当银含量达到一定程度时会有单质银析出，我们认为这是因为银离子在溶胶?凝胶的过程中被还原成单质，以银团簇的形态存在于样品中，随着烧结温度的提高，银原子逐渐被氧化成银离子，取代la ~ ( 3 + ) ，进入晶格，形成钙钛矿结构。
From the result we get the following conclusion : for narrow - band signal , the effect of the method based on fft is best . for wide - band signal , when snr is up to certain degree ( higher than - 7db or so ) , the curves of square error of modified methods are more obvious and closer to crb . for an echo composed of more than one frequency or direction , space - frequency distribution could show more direct information of frequency and direction , which is more advantaged to make precise judge and estimation for doa of echo 从估计结果发现，对于窄带回波信号，基于fft的方法估计性能大大优于其他方法；对于宽带回波信号，在信噪比达到一定程度(高于约- 7db )时，补偿后的几种估计法的性能改善均比较明显，误差曲线越来越接近crb曲线；对于回波中存在多频率多方位的情况，空间?频率分布图能提供较为直观的频率及方位信息，因此应用空间?频率估计法来进行方位估计，更有利于进一步对回波的具体方位进行准确判断和估计。
Fourth , the theoretical model of optimum technological growth rate under discrete change is erected . technology is a unique production factor because technological growth experiences a mutation when technological increase accumulates to a certain extent . under this condition , the point - mutation model in tom ’ s mutation theory is applied to explain the phenomenon of technological 将技术作为不同于劳动和资本的特殊生产要素进行考察，即当技术量的积累达到一定程度时，技术增长会产生突变，在此条件下，运用汤姆突变理论中的尖点突变模型，解释了技术突变现象，讨论了劳动和资本的不同组合变化下，在临界点附近技术突然跃升或下降的突变性质；构建了技术突变完成后的技术增长率优化理论模型。
And it proposes : the cause of first kind of financial crisis is the financial index getting worse evoked by partially inefficent operation of the existing economic system ； the second kind of financial crisis is the financial index getting worse evoked by the moving of subjective value towards objective value after a deviation between them to a < wp = 6 > certain extent prescribed by the existing economic system 提出：第一类金融危机是指由于现有经济体制发生局部性运转不灵而引起的金融指标变坏；第二类金融危机则是指当现有经济体系所规定的主观价值与客观价值的背离达到一定程度时，主观价值向客观价值回归时所引起的金融指标变坏。
