The statistical test based on the Shanghai Composite Index suggested that certain technical trading rules should be able to gain stable excess profit in the long run, which could not be explained by nonsynchronous trading, transaction cost and time variation of expected returns. Thus, it can be concluded that the China's Stock Market is not weakly efficient.

对上证指数的统计检验说明一些技术分析规则可以带来长期、稳定的超额利润，而有效市场假定下的异步交易、交易成本和期望时变性都不能完全解释这种超额利润的存在，因此可以得出中国证券股票市场还没有达到弱态有效性的结论。

Through copolymerizing AA and AN in different mole ratio, and compare the PV performance with membrane of PVA acetal membrane, we can concluded that, the separation flux of composite membrane is less than PVA acetal membrane, however, when the mole ratio of AA and AN is 1:1, the separation factor is higher than PVA acetal membrane, from the view of PSI, the composite membrane is better, thats the reason of the hydrophilic functional group and hydrophobic functional group ratio proper, it achieved good balance.

经过研究得到相对最佳的制膜条件：PVA浓度10％，甲醛浓度36％，采用加热到75℃的方法缩醛和制膜，热处理时间为15min；AA与AN的投料摩尔比为1比1左右，复合膜厚为30gm。通过渗透汽化指数的综合衡量，得到对于共聚复合膜最佳的使用温度为50℃左右。

Simulation results indicate that this method can effectively suppress the Pseudo-Gibbs phenomena in the vicinities of the singular points of the signal due to the discontinuity of the hard threshold function. It also reserves the edge information of the signals under the condition of thorough elimination of noises.

仿真结果表明，采用基于Lipschitz指数的小波阈值去噪方法不仅有效抑制了由于硬阈值函数的不连续性而在信号奇异点附近产生的Pseudo-Gibbs现象，而且在更加彻底去噪的前提下很好地保留了信号的边缘信息。

The minerals of igneous formations were described and a bulk volume model based on mineral and including porosity was established. The logging response equations of density, apparent neutron porosity, acoustic travel time,gamma ray and volume photoelectric cross index were deduced. The volume content of four minerals in matrix was calculated. The igneous rocks were classified according to the international igneous classification scheme proposed by IUGS (International Union of Geological Society).

分析了火成岩中的矿物成分，并基于此建立了以矿物为基础并包含孔隙度的体积模型；建立了密度、视中子孔隙度、声波时差、伽马射线和体积光电吸收截面指数的测井响应方程，计算了岩石骨架中4种矿物的体积含量，依据国际地质科学联合会提出的火成岩矿物分类方案对火成岩进行了分类。

In this paper,through reviewing causality and regression equation of quantity of various price index about the economy of china in recent two decades,I try to uncover the inherent law under which our economy runs,and to probe into the extent to which the economy system exert effort.

通过考察我国20年来的各种价格指数的因果关系和量的回归方程，试图揭示我国经济的内在规律，并探讨我国市场机制发挥作用的程度。

The sample is the data of 100 Index of Shenzhen stock market from the 2nd of January to June 30,and the thesis has made comparative analysis about the different behavior under different market situation of the three kinds of tactics-- the CPPI tactics, CM tactics and TIPI tactics, in the hope of examining the validity of these kinds of dynamic PI tactics in the market of China, and examining whether these kinds of dynamic PI tactics are there different performances under different market situation.

论文以中国2004年上半年(1月2日至6月30日)深证100指数的数据作为样本比较分析了CPPI策略、CM策略和TIPI策略这三种策略在不同的市场状况下的不同表现，以期检验这几种动态PI策略在中国市场的有效性，以及检验这几种动态PI策略是否在不同市场状况下会有不同的绩效。

In the experiment focused on decadal changes, GCMs reproduce the observed NAO shifts in recent decades by imposing strengthening trends on stratospheric wind. The cooling belt extending from North Africa to subtropical Eurasia is simulated accompanying the strengthening of NAO. East end of this cooling belt reaches the eastern flank of Tibetan Plateau.

在强调年代际变化的实验中，通过在平流层中强迫出水平风场的线性增强趋势，大气环流模式可以模拟出近几十年间冬季NAO指数的年代际上升；伴随着NAO正位相的增强，模式可以再现北非至副热带欧亚大陆的冷却带，且其东端可以到达青藏高原下游地区。

At large scale, the result of comparing of optimization structure of forest type with the present structure of forest type illustrates that the present economical forest area is larger while the mixed forest is smaller. So decreasing economical forest area and increasing mixed forest area should be the main measurements to optimize spatial patterns. At small scale, the evaluation of the landscape inner structure index illustrates that the forest structure and coverage is smaller, which should be regulated and so the uneven-aged, multi-layered and mixed forest should be the object of the forest structure design.

大尺度上根据植被类型优化结构和现有植被类型结构数据的对比分析可知，现有经济林面积则过大，混交林面积较小，因此主要是减少经济林面积，改造针叶和阔叶纯林为混交林，从而增加混交林面积，以达到最优植被类型结构时的空间配置；在小尺度上通过对景观内部结构指数的计算分析可知，该区林分结构和郁闭度分指数值较小，应予以着力调整；由研究结果可知，异龄、多层次、混交的水源保护功能最好，因此稳定的林分结构设计目标就是尽量使林分形成异龄、多层次、混交林。

We proposed the time-changed dynamic models of radar signals based on dynamic theory, and can analyze quality and quantity of the deinterleaving pulse train;(2) We proposed the algorithm to computer selfsimilarity exponent and detect successfully the object echo buried in noise according to self-similarity of noise and nonsimilarity of sine wave;(3) We also proposed a nonlinear dynamic filtering detection model.

1根据动力学理论，提出了雷达信号的时变动力学模型，利用这个模型可以对已经分选出来的雷达信号进行定性和定量分析；(2)提出了快速计算自相似性指数的算法，并利用噪声和正弦波分别具有自相似性和不具有自相似性的特点，成功地检测到淹没在噪声中的目标回波；(3)提出了一种非线性动力学滤波检测模型。

Stock analysts sometimes like to note that the Dow today is worth 27 times its value at its 1929 pre-crash peak, meaning that even if you bought at the worst moment, your stock still would be way up over time.

股票分析师有时会指出，道琼斯指数的价值目前是1929年崩盘前高点的27倍，也就是说，即使你是在最糟糕的时刻购买的，你的股票仍会随着时间的推移而上涨。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
