Sequencing of antisense DNA analogues by capillary gel electrophoresis with laser-induced fluorescence detection

A method using capillary gel electrophoresis with laser-induced fluorescence detection is described which permits complete sequence determination of antisense DNA analogues of unknown sequence. This method, originally created as a tool to confirm the sequence of antisense oligonucleotides being developed as therapeutic drugs, utilizes data collected under a range of experimental conditions described by the Ogston model as applied to gel electrophoresis. A linear relationship independent of experimental conditions between the relative electrophoretic migration time and the oligonucleotide base number was observed and is shown to be consistent with a simplified version of this model and can be used to facilitate the sequence determination.

地下洞室形状优化设计

洞室开挖会使围岩周边产生应力集中 ,产生拉应力与压应力。围岩出现拉应力对洞室稳定十分不利 ,通常通过改变洞室形状和轴比来消除围岩中的拉应力。本文提出一种使洞室拉应力σθ=0 ,而压应力最小的确定洞室最优几何形状的方法。     

边剖分、点扩张与图的最大亏格的可约性

设γM（G）是连通图G=（V，E）的最大亏格，记EM^-（G）={e∈E(G)|G\e连通，且γM（G\e）=γM（G）}。若EM^-(G)≠0，则称G是γ（G）-可约的；否则称G是γM（G）-不可约的。本文证明了边的剖分不改变图的最大亏格可约性，点的扩张不改变上可嵌入图的最大亏格可约性；并给出了两类满足EM^-（G）=E（G）的非4-边连通图。     

离心力场作用下多孔介质中强制对流换热的研究

对离心流化床中空气通过多孔物料层的强制对流换热进行了理论和实验研究。获得了气流和物料间强制对流换热的准则关联式。研究结果表明,在气流速度和温度梯度方向一致的条件下,强制对流换热比通常的边界层强制对流换热有所强化,其换热的准则关联式具有 Nu=CRePr的线性形式。从而验证了改变气流方向和热流密度矢量之间夹角可以强化换热的这一强化传热新原理。
