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。     

梅州市五华县石灰岩矿区土壤铅污染现状研究及改良对策

对梅州市五华县几个石灰岩矿区周边土壤中铅含量进行了测定，结果表明，污染土壤的铅含量远远超出了国家土壤环境质量三级标准（对土壤生态环境产生影响的最低浓度值），对生态产生影响。根据内梅罗污染指数评定得出，矿区土壤铅污染达到重污染的程度。提出了减轻铅污染对生态环境危害的控制污染源措施和改良对策。     

浅谈农村环保型养鸡

针对农村养鸡现状与存在的问题，提出在选种、饲料的科学配合、饲养管理制度、合理用药以降低药物残留、加强养鸡场内外环境保护等方面，建立具有农村特色的环保型养鸡模式。     

木捆排排型参数对其运行水阻力影响的试验研究

本文研究了木捆排在无限水域中的运行水阻力问题,提出了排型参数(L/B)和(B/T)对木捆排运行水阻影响程度的试验数据和图表,探讨了降低木捆排运行水阻力的途径及措施。     

冻融中土壤的水热动态

根据在北京郊区的试验,认为土壤水冻融过程可分为三阶段,其中第二阶段有聚墒现象,平均聚墒8.6mm,所聚的墒在融化过程中又逐渐消失。气温回升至-2℃左右是冻层下部由冻到融的转折温度。冬灌水保存到来年春季的数量有限,本试验中1m 土层内平均不足20mm。     

香菇简易开放式栽培高产菌株的早期鉴定

试验对５个香菇菌株进行简易开放式栽培并观察其特性，发现菌丝生长速度、锁状联合数与生物学效率相关性不密切，香菇的酶活性，子实体形成所需时间、子实体单重、菌盖重与生物学效率密切相关。

Analysis of Growth and Productivity of Indian Mustard (Brassica juncea) in Relation to FYM, Nitrogen and Source of Fertilizer

A field experiment was conducted during the winter seasons of 1992–93 and 1993–94 at Anand to study the effect of FYM, nitrogen and source of fertilizer on growth and yield of mustard [ Brassica juncea (L.) Czernj & Cosson]. The results showed significant variation in leaf area index (LAI), crop growth rate (CGR), dry matter production and seed yield. The direct effect of farmyard manure (FYM) was conspicuous in improving the growth of mustard. FYM application at 10 tonnes ha⁻¹ significantly increased the LAI, CGR and dry matter accumulation per plant at almost all the stages during first year study (1992–93) and in pooled analysis. Similarly, nitrogen application registered maximum LAI, CGR at 75 kg level and RGR and NAR at 50 kg level at almost all the during both years. Sulphur carrying source (Ammonium sulphate plus single super phosphate) increased all stages growth characters. Maximum dry matter accumulation per plant and seed yield were recorded with highest levels of FYM (20 tonnes ha⁻¹), N (75 kg ha⁻¹) and source having S. Seed yield was strongly associated with LAI and dry matter accumulation per plant at all the stages.     

四川低山丘陵地区多年生冷季型优良牧草引种试验

2001～2003年在四川省洪雅县对从国内外引进的15个多年生冷季型牧草品种的生育状况、产量、营养品质等指标进行了试验研究.结果表明:由于气候原因紫花苜蓿和百脉根不能结实;白三叶品种Ladino和紫花苜蓿品种Amerigraze702的产草量最高,而单位面积粗蛋白质产量最高的是红三叶品种Cherokee;所引进的禾本科牧草中只有鸭茅品种Pennlate可以越夏.     

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)]
