新世纪新阶段的伟大行动纲领

十六大报告立足高远，气势磅礴，内涵丰富，思想深刻，是一篇马克思主义的纲领性文献。报告其内容而言，可以概括为“一个主题”、“一条主线”、“一个目标”；就其特征而言，主要表现为“理论性”、“时代性”、“实践性”三大特征；同时，十六大报告还提出了许多新思路、新论断、在多方面发展了马列主义、毛泽东思想、邓小平理论。认真学习十六大报告，是当前一项重要的政治任务。     

简论"三个代表"重要思想及其"三进"

“三个代表”重要思想已经形成一个新的科学理论体系，是新世纪的马克思主义。我们高校必须把“三个代表”重要思想“三进”工作作为当前和今后“两课”教育教学工作的头等大事来抓。其关键是加强领导，进教师的头脑。“三个代表”重要思想只有进入了教师头脑，才能确保“三进”的落实。

固态焊接中的等效压缩变形及应力应变分析

对固态压接升温、保温过程中存在的等效压缩变形现象及其产生进行了阐述，并在试验基础上对伴随等效压缩变形的应力应变进行了分析。结果表明：等效塑性压缩变形是焊件在升温、保温过程中受约束压力作用不能胀大而产生的塑性变形的累积，它提供了形成固态焊接接头所必需的塑性变形。等效压缩变形使焊件在被约束方向上的尺寸保持恒定，而约束压力则在焊件由表及里温升的差异、屈服极限随温度变化的不均匀性以及应力松弛的综合作用下发生增大、持平、快速减小直至缓慢减小的变化。

A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)

Severe Acute Respiratory Syndrome (SARS) is a newly identified infectious disease[1—5]. The global outbreak of SARS has been threatening the health of people worldwide and has killed 353 people and infected more than 5462 in 27 countries, as reported by WHO on April 29, 2003 (http://www.who.int/csr/sarscountry/en). Although it has been recognized that a variant of virus from the family of coronavirus might be the candidate pathogen of SARS[1—5], its identity as the unique pathogen sti…     

A surface-based DNA algorithm for the minimal vertex cover problem

Abstract DNA computing was proposed for solving a class of intractable computational problems, of which the computing timewill grow exponentially with the problem size. Up to now, many achievements have been made to improve its performance and increase itsreliability. It has been shown many times that the surface-based DNA computing technique has very low error rate, but the technique hasnot been widely used in the DNA computing algorithms design. In this paper, a surface-based DNA computing algorithm for minimal ver-tex cover problem, a problem well-known for its exponential difficulty, is introduced. This work provides further evidence for the abilityof surface-based DNA computing in solving NP-complete problems.     

Therapeutical effect of Shengmaisan is determined by the interaction among the three herbs

Shengmaisan is a recipe of traditional Chinese medicine, which is composed of three herbs. The interaction among the components from the three herbs of Shengmaisan is investigated using FT-IR, Matrix Assistant Laser Desorption/Ionization Time of flight mass spectrometry (MALDI TOF MS) and TEM observation. Interactions among various components from different herbs cause enhancement of the solubility of some component and suppression of the solubility of others. Results from MALDI-TOF MS show that some components found in the decoction from a single herb disappear when different herbs are decocted together. On the other hand, new substances are produced when two and/or three herbs of Shengmaisan are decocted together. TEM showed that vacuoles formed in the decoction from two and/or three herbs of Shengmaisan but did not occur in any decoction from a single herb. This result provides us direct evidence that the solubilized structure is formed by the interaction among the components from different herbs. This knowledge helps us to understand the therapeutical effects of traditional Chinese medicine.
