双低白菜型91-10油菜高产栽培模式研究

采用三因素五水平正交试验设计，建立白菜型油菜“９１－１０”的产量与播期、密度和施肥的数学模型。结果表明：施肥对产量的效应最大，但各因素间互作效应明显。降低留苗密度，适期晚播，增施肥料有利于产量的提高。在本地区三因素的适宜范围为：直播期１０月１２～１８日，留苗密度２７～３６万／ｈｍ２，施用尿素３６０～４２０ｋｇ／ｈｍ２。     

稻田养殖福寿螺

福寿螺食性杂、生长快、易繁易养，适应性强，但各地自引种以来通常乐用小池净养，这需一定投入，不利省工节本，极大地限制了发展规模。近年来我们根据福寿螺喜荫怕光的特点．改小池净养为稻田养殖，做到扬长避短，趋利避害，取得了明显效果。     

A novel shuffled frog leaping algorithm for ICPT power programming

A new mode of inductively coupled power transfer (ICPT) is presented to city electrization traffic vehicle power supply optimization. The power supply distribution plan and ICPT technology are investigated. To avoid the local optimal of shuffled frog leaping algorithm (SFLA),a novel algorithm based on mutative scale chaos search and SFLA is presented. It is applied to inductively coupled power transfer substation optimal planning. The advantages of global and local search strategies for SFLA are combined with the proposed algorithm. In order to implement local refined search to improve local chaotic search ability and to enhance the solution accuracy, mutative scale chaos search is introduced to the proposed algorithm. The minimum annual expense of the proposed algorithm is 2.39% less than that of SFLA, which shows its advantage.     

Research on Penalty Effect of Listed firm'' Information Disclosure Violation

The listed firm' information disclosure violation is the expectation result of violation cost-benefit under improper Corp governance. The information disclosure violation penalty imposed by CSRC and Stock Exchange doesn't prevent the violation behavior. The author puts forward Penalty effect issue of information disclosure violation and applies SUR event study method to statistical data. The empirical study yields several findings: 1) the penalty doesn't have enough intensity; 2) market response correlates to disciplinary action with publicity and severity; 3) penalty as a whole doesn't increase the violation cost. At last the paper presents some propositions based on the empirical analysis.     

稻茬小麦田间作蔬菜的效应及种植模式

水稻—小麦连作是里下河地区主要的种植方式。近年来,随着农村商品经济的发展,传统的纯粮生产已不再适应农户的要求,因此在保证农田主产业的基础上,如何通过立体开发来增加农田收入,是生产上迫切需要解决的问题。前些年,各地对稻田种养技术研究不少,但对麦田立体种植还缺乏系统研究。1985～1988年,我们对稻茬小麦田间作的产量、经济效益及主要技术指标进行了探索,现将结果整理如下,供生产上参考应用。     

无公害优质米的生产与开发

农药与化肥的大量使用已严重威胁到人类的健康。据统计．每年全世界农药的用量高达23亿公斤，每年死于农药中毒的人数在50万人以上。食物中残留农药对人体的危害，越来越引起世人的普遍关注。为了不让过多的农药随食品进入人体，FAO／WHO制定法规．限制各种食品中农药最大残留量(MRL)，
