论职务犯罪黑数

职务犯罪黑数是指已经实际发生但司法机关尚未发现或未作处理的职务犯罪数 ,我国职务犯罪黑数较大是不争的事实 ,职务犯罪的内在特征与法制环境的消极方面是导致这一现象的深层原因 ,应当认识到职务犯罪黑数的社会危害性与一般规律 ,采取相应措施遏制其增长。     

高产抗病柱花草新品种选育 II高产抗病柱花草品种比较

于 1998 - 2 0 0 0年选择 12个柱花草Stylosanthesguianensis新种质进行品种比较 ,结果表明 :Mineirao柱花草、GC15 81柱花草年干草产量分别为 116 5 0 0kg/hm2 和 114 2 0 0kg/hm2 ,高于热研 5号柱花草 (9831 1kg/hm2 ) 18 5 0 %和 16 16 % ;抗旱性强 ,在冬春低温干旱季节的干质量占年产量的 2 9 2 5 %和 2 9 15 % ;较抗柱花草炭疽病 ,试验期内平均病级分别为 1 6 7,1 74 ;植株越冬存活率分别为 30 83%和 4 1 6 8% ,耐寒性强 ;茎叶比为 1 0 3和 1 0 7,营养价值丰富 ,营养生长期粗蛋白含量分别为 15 36 2 %和 11 5 5 0 % ,是优良的柱花草新品种。     

Evaluation of Wheat (Triticum aestivum) and Legume Intercropping Under 1:1 and 2:1 Row-replacement Series System

A field experiment was conducted during the winter season of 1992–93 and 1993–94 at Agricultural Experimental Farm, Giridih, Bihar to evaluate the intercropping systems of legumes, gram ( Cicer arietinum L.), pea ( Pisum sativum ) and lentil ( Lens culinaris ) with wheat ( Triticum aestivum ) in 1:1 and 2:1 'row replacement series'. Intercropping systems were assessed on the basis of new indices termed as actual yield loss (AYL) and intercropping advantage (IA). This paper highlights the comparative effectiveness of evaluating the intercropping systems through the existing intercropping indices like LER, RCC, aggressivity. The indices AYL and IA seem to be more appropriate particularly when per plant yield is considered. Intercropping reduced the yield of component crops compared with respective pure stands. Wheat + pea in 1:1 row replacement series gave the highest wheat yield equivalent value (3.02 t ha⁻¹) followed by wheat + lentil (2.91 tha⁻¹). When the actual sown proportion was considered wheat + lentil (1:1) resulted in maximum AYL (+0.610) and IA (+0.279) values. This treatment also gave the maximum monetary advantage (Rs 5985.45 ha⁻¹).

鹰咀豆品比研究

本文从世界热带半干旱作物研究中心“ＣＩＣＲＩＳＡＴ”引入鹰咀豆（ＣｉｃｅｒａｒｉｔｉｎｕｍＬ．）品种材料１１２份，在引种筛选的基础上筛选出１７个优秀品种材料，进一步作了品比试验，得到：Ａ３、Ａ２１、Ｂ５、Ｂ７、Ｂ１０、Ｃ１、Ｄ４、Ｄ５８个引入品种。它们抗性强，植株发育生长良好，分枝多，结英率高，种子在甘肃河西走廊可完全成熟，百粒重、籽实产量等均显著地优于当地品种。可在甘肃部分干旱半干旱地区示范性推广，丰富种质资源。

用生态经济型植物控制豚草的"绿色污染"

豚草是一种严重危害农业生产、人体健康和生物环境的恶性杂草，是一种典型的“绿色污染”。根据群落演替规律，采用具有生态和经济功能的树种创造不利豚草生长的环境，人为创建多物种和谐共存的植物群落，能降低豚草的种群优势，使单一种群优势转变为良性演替的生态系统。     

Comparative lipid and lipoprotein metabolism

This review summarizes a number of recent reports in several areas of lipid and lipoprotein metabolism. Absorption of dietary lipids, cholesterol synthesis, and biliary cholesterol metabolism are mentioned only briefly to be complete. Comparative aspects of lipoprotein metabolism, however, are detailed in an effort to integrate the myriad metabolic events which characterize these important lipid transport particles. Where comparative information is known, those aspects of lipoprotein metabolism that may be protective against atherogenesis in certain mammalian species are also described. Efforts to understand atherogenic resistance comparatively in animals lends a better understanding of the metabolic events leading to coronary artery disease in humans. They also provide an important basis for understanding lipid metabolism in numerous veterinary species.

窥探我国果农的合作之路

改革开放以来,我国果业迅猛发展,但产销体制很不完善,产品本身不等于商品,更不等于有了稳定畅销的渠道和市场份额。分散的个体果农户面对竞争的市场,犹如汪洋大海中的叶叶扁舟,显得无能为力。果农协会组织和引领分散果农走向市场,作为利益共享、风险共担的非盈利组织形式,在国外已经是成功的经验和模式,应成为我们之鉴。为振兴我国果业,合作化是我国个体果农的必由之路。果农协会应当实行完全民主化运作,避免“权力”的介入而使之变为“半官方化”、“机关化”和“官僚化”。政府应在制订政策条例、协助开拓市场、科技服务等方面发挥其作用。果农的教育和科技水平亟待提高,民主意识亟待培养和增强。政府在这些方面大有可为。
