关于我国设立刑事证据开示制度的思考

1996年《刑事诉讼法》的修改，产生了律师阅卷难问题。为解决这一问题，真正实现控辩双方公平对抗，我国应设立刑事证据开示制度。文章对刑事证据开示制度的内涵、设立的必要性、设立的原则以及具体建议进行法律思考。     

水稻耐盐机理的研究Ⅲ.不同基因型对NaCl吸收和运转的动力学比较

本文应用动力学研究方法比较了具有不同耐盐性的3组共6个水稻基因型对NaCl吸收和运转的差异,结果表明,在外部低NaCl浓度(0.1mmolL~(-1)时,水稻对Na~+的吸收为被动吸收,耐盐基因型对Na~+的吸收速率显著低于盐敏感基因型;对Cl~-的吸收为主动吸收,不同耐盐性基因型吸收Cl~-的动力学参数(V_(?)、K_(?))差异不显著,在外部高NaCl浓度(50mmolL~(-1))时,耐盐基因型对Na~+和cl~-的吸收速率均低于对应的盐敏感基因型。耐盐基因型水稻的Na~+、cl-从根部向地上部的运转率低于对应的盐敏感基因型,这种差异在高盐浓度时更为明显。表明了耐盐基因型水稻地上部对NaCl的排斥作用是吸收控制和运转控制共同作用的结果,使地上部Na~+、Cl-含量相对降低而显出较高的耐盐性。     

河南小尾寒羊产肉性能与羊肉品质的分析研究

就河南小尾寒羊的产肉性能和羊肉品质进行了分析研究。结果表明:河南小尾寒羊生长发育快,产肉性能好,肉质细嫩,肉味浓郁,6月龄的屠宰率较高。肌肉中的蛋白质含量较高,氨基酸含量丰富,其中的赖氨酸、异亮氨酸等达到或超过了标准蛋白质中的含量。     

Quantitative site classification in the key county in the conversion of farmland to forests project

According to the requirements of the conversion of farmland to forests project (CFFP), we investigated the vegetation factors and environmental factors from more than 6,105 sub-compartments in Liangcheng County, Inner Mongolia by using the Matlab, analytic hierarchy process (AHP), and the hierarchical cluster method (HCM). The site conditions were classified quantitatively. The results show that CFFP at this site comprises five site-type groups and 19 site types. A quantitative site classification system method has been established in this paper. __________ Translated from Journal of Beijing Forestry University, 2005, 27(6) [译自: 北京林业大学学报, 2005, 27(6)]     

贵州省退耕还林与农村经济发展研究

通过对贵州省贞丰、桐梓、锦屏等若干县市林业生态建设监理、检查、造林实绩核查等工作的实践和研究，认为退耕还林工程与农村经济发展相结合，目前应加强以下工作：选择林业主导产业；林产业时间、空间的合理布局；树种、林种的结构优化；林业体制创新；实施相关配套工程。     

浙江淳安新安江开发公司封山育林效益研究

浙江省淳安县新安江开发公司所属16个国营林场22475.53hm~3荒山迹地,封山育林30年,现有天然次生林总蓄积量135万m~3,年总生长率8.07％,活立木直接经济价值2.25亿元。到1987年止公司已获中间利用净收入2135万元。近20年累计天然次生林比无林地多涵蓄水10亿m~3,每年进入水库的泥沙量减少80％,对调节水库水源、延长发电年限、纯洁水质都起到良好作用。公司长期实施的5项管护技术,把封山育林提高到科学经营水平,在千岛湖区成功地建立了森林生态屏障。     

Effects of three methods of restraint an in rhesus and african green monkeys intravenous glucose tolerance testing

The intravenous administration of 0.75 gm glucose per kg and the measurement of serum glucose pretest and at 10, 20, 30, 60, 90 and 120 minutes constitute a satisfactory protocol for intravenous glucose tolerance testing of Rhesus (Macaca mulatto) and African Green (Cercopithecus aethiops) monkeys. No significant differences were noted between animals restrained with ketamine hydrochloride and those restrained with sodium pentobarbital, but the African Green males and females and the male Rhesus monkeys yielded significantly different results while being manually restrained.     

The intravenous bile Acid loading test in the goat: determination of a procedural protocol and reference values

An intravenous bile acid loading test was performed on 16 goats using various dosages and sampling protocols. A recently developed enzymatic bile acid assay provided an economical and technologically simple method for bile acid analysis. Intravenous injection of bile salts into goats was well tolerated. Clearance times were rapid. A protocol for performance of the test was suggested and a practical reference range for T 1/2 clearance of 4+/-1 minute was determined. Further investigations of this test in the assessment of liver function in the ruminant appear warranted.     

The metabolism of R-20458 [(E)-6,7-epoxy-1-(4-ethylphenoxy)-3,7-dimethyl-2-octene] in rat hepatocyte suspensions

The metabolism of R-20458 [(E)-6,7-epoxy-1-(4-ethylphenoxy)-3,7-dimethyl-2-octene] by rat hepatocytes has been analyzed and compared with that of juvenile hormone I [methyl-(E,E)-cis-10,11-epoxy-7-ethyl-3,11-dimethyl-2,6-tridecadienoate] under identical conditions. The metabolism of R-20458 is characterized by the predominance of NADPH-dependent cytochrome P-450 and epoxide hydrolase reactions; whereas, JH I is metabolized mainly by carboxylesterase, epoxide hydrolase, and glutathione S-transferases. The metabolites of R-20458 have been shown to correspond to (E)-6,7-epoxy-1-(4-hydroxyethylphenoxy)-3,7-dimethyl-2-octene; (E)-6,7-epoxy-1-(4-acetylphenoxy)-3,7-dimethyl-2-octene; (E)-6,7-dihydroxy-1-(4-ethylphenoxy)-3,7-dimethyl-2-octene; and, (E)-6,7-dihydroxy-1-(4-acetylphenoxy)-3,7-dimethyl-2-octene. The production of the α-hydroxyethyl, p-acetylphenoxy, and acetylphenoxy-6,7-diol metabolites is markedly inhibited by SKF 525-A. No dramatic effects are produced by diethylmaleate and 1,2-epoxy-3,3,3-trichloropropane.
