5.Methods Platelet rich plasma(PRP)was prepared routinely from venous blood samples of pa- tients with essential hypertension and normal persons. PRP was incubated with different concentrations of Nifedip- ine,Ginsenoside-2A,and SK&F96365.Maximal platelet aggregation rate[PAG(M)]induced by 2μmol/L ADP was taken as the observed index.

7.This paper first described the construction regulations and major properties of Diffusion-limited- aggregation model (DLA model), which is a typical fractal growth model. And then one algorithm to realize the dynamic growth process was introduced and complemented on the MATLAB6.5 platform in Windows98/2000/XP.

8.Abstract By setting up a network model of data aggregation and using a bit-hop metric to quantify energy costs in wireless sensor networks, we formally analyze the problem of area-based data aggregation and obtain that data aggregation will definitely be energy efficient when the relative difference between the average lengths of the two shortest paths, which are from source sensor nodes to the sink and to the aggregation node respectively, is not less than the ratio of data correlation to the number of source sensor nodes.
摘要通过抽象出无线传感器网络中区域数据回传的网络模型，定量研究了区域数据聚合的节能条件，证明了先聚合再回传比直接进行数据回传所节省的相对路径长度,如果大于等于数据相关性与源节点个数的比值时，区域数据聚合一定可以节省能耗，并进一步给出了当数据聚合点在网络的不同位置，或数据的空间相关性不同时，区域数据聚合的节能条件。
9.The innovative points of this thesis included: (1) A model was proposed to simulate the aggregation process of nano-particle aggregation process by thermodynamic methods, the relationship between aggregation rate and aggregated particle number was derived. (2) ACPA initiator was chelated directly onto the nan-CaCO3 surface by the action of ACPA with Ca+, or nano-CaCO3 was first modified with 3-aminopropyltriethoxysilane, followed by the reaction with ACPA.
将偶氮二氰基戊酸(ACPA)螯合到纳米CaCO_3表面,接着进行MMA分散聚合,研究聚合动力学和表面接枝行为,发现螯合引发剂分解温度略有降低,引发活性增加;
10.Results: Ginkgo flavones obviously inhibited Aβ1-42 aggregation and fibrogenesis as well as the aged Aβ1-42. The less aggregation Aβ1-42 and unobvious fibrogenesis Aβ was observed under TEM because of the availability of ginkgo flavones.
