A new method is proposed to inverse normalization data of hidden variables in a dynamical system by embedding a time series in multidimensional spaces and applying a normalization analysis to the conditional probability density of points in the reconstructed phase spaces. The method is robust in the application to Lorenz system and 4-dimensional R?ssler system by testing quantitatively and qualitatively the correlation coefficient between inverse data and original data in time domain and in frequency domain, respectively. By applying the method to analyzing the South China Sea data, the normalization data of wind speed is extracted from the sea surface temperatu-re time series.

电影发行的新媒体渠道

北京电影学院学报 2011年第1期 8-10页

作者：谷国庆华夏电影发行有限责任公司

现在我国的电影业有一大难题是银幕数量远远不能满足放映需求。2000年在WTO培训的时候,美国电影每年700部左右,但真正能上市的只有400部左右,所以中国电影现在能上市的达到456—500部之间也是正常的。

In order to investigate the microstructural evolution during self-propagating high-temperature synthesis （SHS） of Ti-Al powder mixture with an atomic ratio of Ti： Al=1：1, a combustion front quenching method （CFQM） was used for extinguishing the propagating combustion wave, and the microstructures on the quenched sample were observed with scanning electron microscope （SEM） and analyzed with energy dispersive spectrometry （EDS）. In addition, the combustion temperature of the reaction was measured, and the phase constituent of the synthesized product was inspected by X-ray diffraction （XRD）. The results showed that the combustion reaction started from melting of the Al particles, and the melting resulted in dissolving of the Ti particles and forming of Al3Ti grains. As the Al liquid was depleted, the combustion reaction proceeded through solid-state diffusion between the solid Al3Ti and the solid Ti. This led to the forming of TiAl and Ti3Al diffusing layers. In addition, the combustion reaction is incomplete besides TiAl, there are a large amount of Ti3Al and TiAl3 and a small amount of Ti in the final product. This incompleteness chiefly results from the using of coarser Ti powder.

The helium Ⅱ hydrodynamic equations constructed by Landau and Khalatnikov (LK equations) have laid a foundation for describing hydrodynamic behaviours of helium IL The results derived from the LK equations were proved to be valid by experiments in the past decades. But, along with the advance of experimental techniques, the intrinsic difficulties in LK theory were also revealed, a serious one

砂土材料常压至高压下的强度、变形特性是构建砂土模型的首要问题。开展3种粒组砂土8 MPa围压范围内的等向压缩试验以及0.2~6.4 MPa围压范围内的三轴剪切试验,将砂土常压至高压范围内的力学特性进行系统分析,以获得能够将常压至高压范围内的强度、变形特性进行统一描述的力学参数。通过研究发现：（1）砂土在高压下出现一定量的颗粒破碎,改变了砂土的剪切耗能机制,使得砂土三轴压缩剪切由剪胀软化特征向剪缩硬化特征转变;（2）砂土材料的三轴压缩剪切峰值应力比受砂土粒径、围压共同影响,M-C强度准则在高压条件下不再适用;而残余应力比则基本不受粒径、围压的影响,是典型的无黏性摩擦型岩土力学参数,应作为砂土基本力学特性指标;（3）砂土材料在常压至高压范围内的剪切过程中存在较明显的临界状态现象,临界状态曲线与等向压缩曲线形态相同均呈指数衰减型并在高压条件下产生交叉,两者共同构成砂土材料的状态区间能够体现常压至高压范围内的剪胀与剪缩特征。
