卤化物与水玻璃复合物的抑尘性能

在恒温箱中测定了粉尘试样添加ＣａＣｌ２或ＭｇＣｌ２和水玻璃后的含水率与环境温度、湿度、有效抑尘时间等因素之间的关系．研究结果表明：（１）当环境温度低于３１℃，相对湿度高于６０％，粉尘试样中ＣａＣｌ２和水玻璃含量的质量分数分别达到２０％和１０％（ＭｇＣｌ２和水玻璃含量的质量分数为２３％和１１．５％）时，试样的含水率就能保持大于５％（质量分数）；（２）当环境温度低于４０℃，相对湿度高于５０％，粉尘试样中ＣａＣｌ２和水玻璃含量的质量分数分别达到２６％和１３％（ＭｇＣｌ２和水玻璃含量的质量分数为３０％和１５％）时，试样的含水率就能保持大于５％（质量分数）；（３）ＣａＣｌ２或ＭｇＣｌ２与水玻璃复合后，其粘尘功能进一步增强，而且其溶液的弱酸性得到进一步降低。

Remote sensing of spatial patterns of urban renewal using linear spectral mixture analysis: A case of central urban area of Shanghai (1997―2000)

It is very important to integrate remote sensing with urban geography that the spectral mixture analysis technique is applied to urban land cover evolvement and its eco-environmental effect. Urban land cover is mainly composed of complicated artificial materials, which is the key factor to limit the development of the spectral mixture analysis technique. There are two main aspects in which the technique of spectral mixture analysis is applied to urban geography： one is to calculate vegetation fraction; the other is to build quantitative model of the urban impervious surface obtained from the combination between high albedo fraction and low albedo fraction. The technique of spectral mixture analysis is firstly applied to study urban renewal pattern, scale and mode which happened in Shanghai City from 1997 to 2000,     

Strategy for the mapping of interactive genes using bulked segregant analysis method and Mapmaker/Exp software

A qualitative trait is usually controlled by a single gene, but it may be sometimes controlled by two or even more genes. This phenomenon is called gene interaction. Rapidly searching for linked mo- lecular markers via bulked segregant analysis (BSA) and then constructing regional linkage map with Mapmaker/Exp has become a common approach to mapping single major genes. However, methods and computer programs developed for mapping single major genes cannot be simply applied to interactive genes because the genetic patterns of gene interac- tions are quite different from that of single-gene in- heritance. Up to now, experimental methods for quickly screening molecular markers linked to inter- active genes and statistical methods and corre- sponding computer softwares for simultaneously analyzing the linkage relationships of multiple mo- lecular markers to an interactive gene have not been available. To solve this problem, in this paper, we propose a strategy for mapping interactive genes using BSA and Mapmaker/Exp. We demonstrate that all interactive genes can be mapped by the 'BSA Mapmaker/Exp' strategy using F2 generation (in a few cases, F3 generation is also needed). As BSA and Mapmaker/Exp have been broadly used in gene mapping studies and are well known by many re- searchers, the strategies proposed in this paper will be useful for practical researches.

用于多指数拟合的一种混沌免疫粒子群优化

为了更好地逼近真实物理场景,对传统的多指数模型作了一些改进,将权因子设置为噪声方差平方的倒数,提出一种基于循环矩阵(CM)的算法用于估计衰减项数.为了求解上述改进模型,提出一种混沌免疫粒子群优化(CIPSO)算法.该算法将人工免疫系统中的克隆、交叉、变异和接收器修正算法嵌入粒子群算法中,并采用混沌算子实现变异,然后将惯性因子改为自适应变化.实验表明:提出的权因子设置更符合实际;用于估计项数的CM算法在估计精度与运行时间上均优于传统的ILS算法;CIPSO算法在收敛精度与运行时间上也优于传统的优化算法,如可信域法、LM法、高斯-牛顿法、差分进化算法和粒子群算法等.
