First of all, the report introduced evolution, achievments and problems in the study of anisotropy in the inner of earth. The first-order hyperbolic system of equations is work out, which is used to describe the wave motion in 2D transversely isotropic media. Utilizing the characteristics of free-divergence, We have imposed MacCormack theme that is used to simulate multicomponent records in anisotropic media and have developed a fast high order vectorized finite-difference algorithm adapted for the vector supercomputer.

Base on the China's limit order-driven electronic trading system,such factors as the stock price,the depth of market,the probability of informed trading, the fluctuation of stock price,the impact of information and the imbalance of orders will all affect the implicit transaction cost.

4指令驱动制度下的股票市场，隐形交易成本和股价、市场深度、知情交易概率、股价波动、信息冲击与买卖指令的不平衡性密切相关，理论和实证表明：市场深度越大、知情交易概率越小、股价波动越小、信息对股价的冲击越小以及买卖指令的不平衡性程度越低，隐性交易成本就越小。

This method can meet the inconstant characteristic and perfect the distribution of the var flow of complicated power system.

这种方法的缺点在于补偿量不能随电网参数波动而改变，不能动态解决无功分布不合理、电压波动大的问题。

The basic theory and the latest research progress in this field are presented in this paper,and the further research directions in application of manifold PCM, studies on insulation properties of building envelope with PCM and inosculation of PCM and building material are pointed out.

维持室内温度在一定范围(24℃～28℃)内是保持室内环境舒适度的关键。随着季节的变化和昼夜的交替室外环境温度是不断地波动的，为了避免这种波动对室内环境舒适度的影响，人们常常利用空调和供暖系统，但相应的能耗随之增加，环境污染也随之加剧。

The waveform shape analysis based on the fluctuation law of the instantaneous angular speed of diesel engine under normal condition is an important monitoring method.

瞬时转速波形分析法是以柴油机正常态瞬时转速波动规律为判据的分析方法，因此，瞬时转速波动规律的仿真计算非常重要。

When when Ar gas is wrapped by insufflate steel, bubble generates inside steel fluid, ascendant bleb is pounded by fits and break through broken bits layer,; of generation slag blister at the same time, broken bits layer produces wave motion, fluctuant frequency increases as the addition of Ar throughput.

当Ar气被吹进钢包时，在钢液内产生气泡，上升的气泡间歇地冲击并突破渣层，产生渣眼；同时，渣层发生波动，波动频率随着Ar气流量的增加而增加。

With the rapid development of economic integration and constant improvement of degree of openness in the most of countries, intercourse of the trade and financial field becomes more and more frequent. Under this kind of background, economic fluctuation is easy to take place because of external shocks through foreign trade, international capital flow and other channels. So, the research of economic cycle can not be taken only in closed environment. Focusing on the open e conomy, the discussion of influence on the economic cycle fluctuation from external shocks have rather important significance.

随着全球经济一体化的迅猛发展，各国经济开放程度不断提高，各国间贸易与金融领域的交往也日趋频繁，在这种背景下，通过对外贸易、国际资本流动等渠道本国的经济将会受到外来冲击的影响而发生波动，因此，对经济周期的研究不能仅停留在封闭条件下，着眼于开放经济的背景，探讨外来冲击对一国经济周期波动的影响具有相当重要的意义。

When the interconversion factors are studied, investor sentiment is considered to analyze the different effects on stock market and bond market, and individual and institutional investors have different impacts on the spillover effect.

特别是在研究互变因素时，考虑了投资者情绪这一主观因素对两市的波动影响，并且对不同类型投资者在不同市场的行为进行了深入对比研究：个人投资者缺乏理性，往往是市场剧烈波动的始作俑者；而机构投资者能在市场间采取合理的反向操作策略，间接表明他们在稳定市场发展、化解风险扩散中的作用。

Thereinto, nineteen cold/warm climatic fluctuations correspond with stadial/interstadial of GRIP, the five substages are rather consistent with the Guliya ice core in the climatic fluctuating features and phase as well as the North Atlantic climate reflected by the N. pachydema numbers of V23-81 core.

其中，19次冷/暖波动可与格陵兰GRIP冰心δ18O冰段/间冰段相对应，5个亚段与我国古里雅冰心在波动性质和相位上都极为一致，与V23-81冷性浮游有孔虫数代表的北大西洋地区气候也具有较好的可比性。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
