过渡金属乙酰丙酮配合物引发淀粉与烯基单体接枝共聚

研究了Ｍｎ（Ⅲ）、Ｃｏ（Ⅲ）、Ｃｒ（Ⅲ）和Ｖ（Ⅳ）的乙酰丙酮配合物引发淀粉与ＭＭＡ、ＡＮ、ＡＭ和ＡＡ接枝共聚合反应的引发活性。实验表明，４种引发体系中，Ｍｎ（ａｃａｃ）３的引发活性最佳，它可以有效地引发淀粉与上述４种单体的接枝共聚合反应，并获得较高的ＰＧ；Ｃｏ（ａｃａｃ）３和Ｃｒ（ａｃａｃ）３仅对水溶性烯基单体ＡＭ、ＡＡ有良好的引发活性；Ｖｏ（ａｃａｃ）２对４种单体的引发活性均较低。４种单体中，水     

剑桥空间百科全书——任务、应用和探测

自从1957年苏联第一颗人造卫星发射成功后，至今已有30多个国家发射了8000多颗人造卫星和火箭，花费了数亿美元。难以置信的是有超过350人曾遨游在大气层之上，并在数不胜数的空间应用中获益匪浅。     

Heterostructure in ZnO Nano-Tetrapods

1 Introduction 　　Nanoscale science and technology have attracted greatattention since the novel properties become dominant for well-known materials as their sizes reduced to some critical dimension. These properties frequently originate in lattice distortions, structure transformations etc[1]. The variations of size and structure ofnanocrystals lead to the change of their electronic structures. Very recently, nanoscale materials with different electronic structures were utilized in fabricating nanoscale junctions[2]. 　　……

像势对量子阱中类氢杂质结合能的影响

在有效质量近似下，利用变分方法研究了像势对量子阱中类氢杂质结合能的影响。计算中考虑到了阱和垒中电子有效质量的不同。数值计算结果表明：阱和垒中质量的不连续只对阱宽较窄的区域有影响，而像势则在整个区域都有影响．对于阱和垒中介电常数之比较大和阱宽较小的量子阱，考虑像势对阱中杂质结合能的修正是非常必要的

Intelligence service binding architecture for interoperability between home network devices

Existing home devices in home network provides only independent services limited on a homogeneous protocol and/or do not fully support an intelligent service provided by cooperating among heterogeneous protocol devices. This paper proposes an intelligent and integrated service binding architecture which allow the users to figure out the status of devices and to cooperate among home network devices regardless of supported protocols or operational characteristics.     

Finding global minima with a new dynamical evolutionary algorithm

A new dynamical evolutionary algorithm (DEA) based on the theory of statistical mechanics is presented. This algorithm is very different from the traditional evolutionary algorithm and the two novel features are the unique of selecting strategy and the determination of individuals that are selected to crossover and mutate. We use DEA to solve a lot of global optimization problems that are nonlinear, multimodal and multidimensional and obtain satisfactory results.
