淬火工艺对铬结构钢显微组织和机械性能的影响

本文研究了淬火工艺对低和中碳铬钢的显微组织,冲击韧性和断裂机制的影响,得出了无论是低碳,还是中、高碳钢,当奥氏体长大倾向稍大时,采取提高加热温度进行淬火的工艺均为不可取的结论。     

关于少数民族音乐教育中复合型架构模式的若干思考

少数民族音乐教育的属性是“复合性”。在人才培养、教师队伍建设等方面应按照复合型架构模式进行建设。即以汉族音乐教育为基础，少数民族音乐教育为特色，并借鉴西方音乐教育的建构模式，使少数民族专业音乐教育在多成分、多层次平衡发展的基础上，力求双向发展的最大值——向民族纵深和现代化尖端的两极扩展。     

对“有机化合物命名”中存在问题的商榷

2,3-二羟基哌嗪与几种氨基化合物的缩合反应研究

由乙二胺与乙二醛的缩合物２,３－二羟基哌嗪,分别与甲酰胺、脲和乙二胺反应,制得２,４,７,９,１１,１４－六氮杂三环［８,４,０,０３,８］十四烷六盐酸盐四水合物（１）,２,５,７,９－四氮杂双环［４,３,０］壬－８－酮二盐酸盐－水合物（２）和２,５,７,１０－四氮杂双环［４,４,０］癸烷（３）。化合物１为未见文献报道的新化合物。化合物２的合成工艺条件优化后,反应得率与文献［１］相比有一定提高。化合物３的合成,由于将反应分为低温和高温两个缩合阶段,使反应得率提高到７７．５％。

Carbazole-type compounds in crude oils

Carbazole-type compounds were analyzed using GC and GC-MS-MS. A relatively high concentration of carbazole-type compounds was detected in crude oils of different types (marine and non-marine) and different maturities (low mature and mature) in Tarinl. Liaohe and Keilu basins. The results suggest the ratios of 1, 8-dimethyl-/2, 7-dimethylcarbazole and benu, [a] carbazole/benzo [e] carbazole might be taken as petroleum migration parameters.     

Lewis酸的F_A标度及其应用

Ｌｅｗｉｓ酸的电负性（ｘＬ）和原子势（Ｚ／ｒｃ）是影响Ｌｅｗｉｓ酸硬软度（ＦＡ）的主要因素,本文给出了它们之间的数学关系式．根据ＦＡ值大小,把Ｌｅｗｉｓ酸分成三类,这与Ｐｅａｒｓｏｎ分类基本一致．用最小二乘法成功地建立ＦＡ与配合物的ｌｇＫｆ的线性回归方程,均通过Ｆ检验．

2-Carboxyethylgermanium sesquioxide,a synthetic organogermanium compound,as an inducer of contrasuppressor T cells

2-Carboxyethylgermanium sesquioxide (Ge-132), a synthesized organogermanium compound with immunomodulaing activities, was shown to be an inducer of anti-suppressor T cells in normal mice. The suppressor cell activity of T6S cells, a clone of burn-induced CD8⁺ IL-4-producing suppressor T cells, was clearly inhibited when a mixed lymphocyte-tumor cell reaction of the clone was conducted with splenic mononuclear cells from mice treated orally with a 100 mg/kg dose of Ge-132. The activity of anti-suppressor cells was demonstrated in spleens of mice 2 days after treatment with Ge-132 and reached its peak on day 3. The anti-suppressor cells induced by the compound were of a contrasuppressor T cell-linage, because they were characterized as CD4⁺ CD28⁺ TCR/⁺ Vicia villosa lectin-adherent T cells. These cells produced IFN- but did not produce IL-2, IL-4, IL-6 or IL-10 in their culture fluids. CD4⁺ anti-suppressor T cells induced by Ge-132 may be different from other subsets of CD4⁺ T cells because Th1 and Th2 cells generated in our laboratory did not adhere toVicia villosa lectin-coated petri dishes, and each produced specific cytokines. Th1 cells produced IFN- and IL-2 while Th2 cells produce IL-4 and IL-10 in vitro. These results suggest that Ge-132 may be useful as an inducer of contrasuppressor T cells in immunocompromised individuals bearing suppressor T cells. To eliminate suppressor T cells from immunocompromised hosts may result in improved resistance from various opportunistic infections.     

混凝土复合外加剂复合理论和复合设计

以分子结构有无条件形成氢键作为分类标准,将基准外加剂分成两类：一类能形成氢键;一类不能形成氢键,提出复合外加剂是由能形成氢键的基准外加剂和不能形成氢键的基准外加剂两部分组成的新观点,以此观点为基础,作者用数学模式表述复合外加剂和它的复合,将复合外加剂的“组成－结构－功能－名称”有机地联系起来。
