一维连通流形的分类（Ⅰ）

连通的一维流形在同胚的意义之下恰可分成７类，它们分别以下列７个空间作为代表：１）紧致区间［０，１］；２）半实轴［０，∞）；３）实数轴Ｒ；４）单位圆周Ｓ１；５）超穷长半直线［０，ω１）；６）单向超穷长直线（－∞，ω１）；７）（双向）超穷长直线（－ω１，ω１）．     

加权增量卡尔曼滤波法在ICP－AES中的应用

卡尔曼滤波法用于ＩＣＰ－ＡＥＳ分析时，在白色噪音情况下能给出准确的分析结果，当试样的某些组分未知时，测量噪音将不是白色的，分析结果将不准确。本文提出了一种加权增量卡尔曼滤波法来解决这个问题。     

C─余模和有理C~＊─模

众所周知，余模和有理模在Ｈｏｐｆ代数理论的研究中发挥着重要的作用。本文将给出余模与有理模之间的关系，论证在特殊条件下Ｍ＊的最大有理Ｃ＊─子模的刻划问题。     

多层弹性体空间一般问题的解析解

本文利用广义柔度矩阵递推法,成功地导出了多层半无限弹性体空间一般问题,在任意荷载作用和两种层间接触条件下的通解.对于这个通解,不管弹性体的层数为多少,最后均不需再解任何联立方程.作为应用,文末计算了地基位移和应力问题实例.     

联机卡尔曼滤波光度法同时测定混合体系中5种合成食用色素

我国法定可使用的合成食用色素主要有5种。即苋菜红、胭脂红、柠檬黄、日落黄和亮蓝。根据调色需要,它们常被混合配置应用.目前一般采用高效液相色谱和层析分离法分析,但尚缺少可靠的同时测定此5组分的化学计量学方法,Loosbroek曾用卡尔曼滤波光度法鉴

Nanowire‐Based Electrochemical Biosensors

We review recent advances in biosensors based on one‐dimensional (1‐D) nanostructure field‐effect transistors (FET). Specifically, we address the fabrication, functionalization, assembly/alignment and sensing applications of FET based on carbon nanotubes, silicon nanowires and conducting polymer nanowires. The advantages and disadvantages of various fabrication, functionalization, and assembling procedures of these nanosensors are reviewed and discussed. We evaluate how they have been used for detection of various biological molecules and how such devices have enabled the achievement of high sensitivity and selectivity with low detection limits. Finally, we conclude by highlighting some of the challenges researchers face in the 1‐D nanostructures research arena and also predict the direction toward which future research in this area might be directed.     

Two—dimensional Network Crown Ether Complex.Synthesis and Crystal Structure of 18—Crown—6 Complex：[K（18—C—6）]2[Cd—（nmt）2]

The novel complex [K(18-C-6)]2[Cd(mnt)2][18-C-6-18-crown-6,nmt=1,2-dicyanoethene-1,2-dithiolate,C2S2-(CN)2^2-] was synthesized and characterized by elemental analysis,IR spectrum and X-ray diffraction analysis.The complex displays two-dimensional network structure of [K(18-C-6)] complex segments and [Cd(nmt)2] complex segment bridged by S-K-S,S-K-N and N-K-N interactions between adjacent[K(18-C-6)] and [Cd(mnt)2]units.     

Study of the development of thermoresistance in human pancreatic carcinoma cell lines using proteome analysis

In order to find candidate proteins that are potentially associated with the thermoresistant phenotype in combination with drug resistance, we analyzed the differential protein expression in vitro in the human pancreatic cancer cell line EPP85-181-P and classical and atypical multidrug-resistant variants and their thermoresistant counterparts using proteomics. This study identifies sets of proteins that may lead to the development of thermoresistance. These results provide a fundamental basis to elucidate the molecular mechanism of thermoresistance and chemoresistance phenomena that may assist the therapy of inoperable cancers.
