热爆SHS法制备金属陶瓷块体工艺过程研究

用热爆自蔓延高温合成法简便，快捷地制备了钨基金属陶瓷块体，分析研究了影响热爆ＳＨＳ反应的各种因素；经对起始温度和稀释剂对材料气孔率的影响研究发现：起始温度的升高，稀释剂含量的减少，均有利于材料的致密化；而不同起始温度时，稀释剂含量对气孔率的影响存在一最佳值，该最佳值相对应的绝热温度在钨的熔点附近。     

常规情形的股价短期预测

对常规情形的股价走势作短期预测。所谓常规情形是指无政治、政策、利好、利空等消息影响，投资者依据价位、价位变化率等资料作出买卖决定。主要假设：买家的买入量与即时的价位成反比，与即时的价位上升率成正比。而卖家则相反，卖出量与即时的价位成正比，与即时的价位下降率成正比。据此建立动态的控制方程，即递推公式。由行情资料定出系数后，应用于深圳股市预测和检验，误差约１２％。

Demonstration Study on the Intrinsic Characteristic of Stock Complex Index on Shanghai Security Market

This paper takes the Shanghai Security market stock composite index as the research object, analyzes its intrinsic fractal essence characteristics by the application of fractal theory and the method, and computes the Hurst index, fractal dimension and correlated function of the highest prices of the complex index. Moreover, it studies characteristics of long term memory of the sample data and its variance along with time; study existence of chaotic attractors in data of the complex index by reconstructing the phase space of the index data. Finally, this paper carries on the related forecast demonstration study to the stock composite index. Results of the study have certain reference function to the actual problem.     

Relationships of the Monetary Policy, Stock Market and Real Investment in China Based on Markov-Switching Model

This paper studies the relationships of the monetary policy, stock market and real investment in China based on Markov-Switching-Vector Error Correction Model. It shows that there is a cointegration relationship among the three ones. We disclose the riddle that the stock market is in recession, but the growth rate of economy is very high in recent years. We also find that Chinese economy operated stably most of the time during the past 8 years. But if the economy is difficult to continue its high growth, it is more likely to appear ＂hard landing＂ than ＂soft landing＂. The impulse response analysis indicates the asymmetry between the ＂too cold＂ economy regime and the ＂too hot＂ regime. And the economy will oscillate during the subsequent time when it is shocked under the ＂too hot＂ regime.
