汉语思维方式及写作经验在中国学生英语写作中的迁移现象

语言迁移现象会在语言学习的各个方面发生，正迁移对英语学习有促进作用，负迁移则有阻碍作用。写作教学是外语教学中的难点之一和薄弱环节，更容易发生负迁移。运用对比错误分析方法，对中国学生写作时容易发生的汉语负迁移现象进行了分析，试图对我国英语写作教学的改进提供一己之见。     

桃小食心虫卵的空间分布型与序贯抽样

桃小食心虫卵的田间分布以聚集分布为主，而且具有密度依赖性，分布的基本成份是个体群。其Ｉｗａｏ回归式为ｍ－＝０．２６２７＋１．１３１５ｍ，Ｔａｙｌｏｒ回归式为ｌｏｇｓ２＝０．１９０２＋１．１１０１１ｏｇｍ。在分布型的基础上详细叙述了桃小食心虫卵的田间序贯抽样技术，并给出了田间抽样的最大最小抽样数量。     

特旱低温灾害年小麦节水高效栽培模式试验

针对北方井灌区种粮农民投入高收益低的问题,在工程节水的前提下,采取农艺节水技术,以大田实测资料为依据,分析了小麦6个品种在特旱低温灾害年型的生理生态耗水特性和产量性状及节水高效栽培组合模式.试验表明1.63hm2示范田平均浇3.5次水,产量8253.75kg,水分生产率为2.988kg/m3,产出投入比4.11:1,比对照田成本减少11.14%,增产28.35%,耗水量下降23.85%,水分生产率提高69.77%,产投比是对照田的2.96倍,纯收入是对照田的5.86倍,实现了农业增产,农民增收和农村经济走上可持续发展的致富道路.     

企业品牌危机产生机理的综合模式研究

首先分析品牌危机产生的原因可分为急性因子、慢性因子及模糊因子；其次论证了品牌危机产生机理，急性因子在媒体的危机心理效应的释放下，对品牌产生的媒体报道与社会舆论压力经公众的危机心理与企业的危机心理效应释放后，便可能演变成巨大的品牌危机，客户流失引发财务危机与企业全面危机，最终导致企业停产、破产、拍卖或被收购等，品牌生存与发展的根基被架空，品牌危机产生过程受企业品牌与基础管理能力的影响；本文最后论述了品牌危机产生机理对品牌危机管理的启示。     

秦巴山区农村产业结构转换初探

秦巴山区经济发展必须突破传统产业结构的单一性,建立新的产业结构或产业发展格局。新的产业结构转换的方向应是:第一、以粮食生产为基础产业,以林特产业为主导产业,以食草畜牧业、副业等为辅的农业发展格局;第二、以农村工业为主,以农村建筑业和农村商业饮食服务业等为辅的非农产业发展格局。文章最后提出了政策、技术及人才、基础设施及服务体系、人口控制、生态环境改善与经济协调发展为产业结构转换的配套措施。     

养分平衡法配方施肥数据库建模

【研究目的】养分平衡法是一种重要的配方施肥方法,在进行施肥决策时,需要依赖大量的施肥参数进行计算,所以建立数据库对施肥参数进行有效地管理是一项非常重要的工作。【结果】笔者给出了养分平衡法简洁的计算公式,采用实体-关系建模的方法确定了8个实体对象和12个关系对象,并绘制了完整的实体-关系图。【结论】本文的分析对于其他配方施肥方法的参数管理同样具有参考意义。     

红楠群落主要种群分布格局的研究

人才培养模式探析

人才培养模式是对人才培养过程的总体表述，属于过程范畴，它和办学模式、教学模式、培养途径、培养方法等其它教育范畴存在着差异，人才培养模式由培养目标、培养制度、培养过程和培养评价四个子系统的构成，是系统性与独立性的统一，是中介性与操作性的统一，是稳定性与灵活性的统一，是个性与共性的统一。     

Interactive effects of organic fertilizer, CaSO4 and amino acid Ca on Fuji apple in Burozem soil in China

A two-year trial was conducted to test the interactive effects of special-for-apple organic fertilizer, CaSO₄, and amino acid Ca on Fuji/Balenghaitang (Malus robusta Rehd.) rootstock in Burozem soil in China. Total Ca, exchangeable Ca, and fruit Ca were significantly improved by the soil application of CaSO₄ with the highest exchangeable Ca and fruit Ca observed in Fuji apple trees treated at the rate of 3.5 kg CaSO₄ per tree. 3.5 kg CaSO₄ was divided into two applications, with first application in the first month after full bloom, and the second in the second month after full bloom in summer, progressively to improve fruit Ca concentration. Dividing CaSO₄ into two applications in combination with organic fertilizer or amino acid Ca spray, proved to be more effective on improving the fruit Ca concentration, with the highest level of 179.17 mg/kg FW in Fuji apple trees treated with 2 kg CaSO₄ applied and amino acid Ca sprayed in the first month after full bloom, 1.5 kg CaSO₄ applied in summer, organic fertilizer applied in winter. Organic fertilizer applied in winter alone remarkably improved the fruit Ca concentration, as well as storage Ca in roots and stems, and the best effect was observed in Fuji apple trees which were supplemented organic fertilizer (10 kg) in winter and CaSO₄ (1 kg) in the first month after full bloom per tree. The effect on Ca increment became less pronounced when the amount of organic fertilizer reached 15 kg or CaSO₄ was more than 3.5 kg per tree. There was a positive correlation between the Ca/Mg ratio in soil and fruit, exchangeable Ca, and fruit Ca concentration, while a negative correlation was observed between the N/Ca ratio in fruit, available P, available K in soil, and fruit Ca concentration. Both N/Ca ratio and Ca/Mg ratio in fruit were affected by different fertilization regime, and bitter pit incidence at the end of storage kept acceptable only if N/Ca < 17 and Ca/Mg ≥ 7 at harvest. The commercial fertilization regime turned out to be organic fertilizer in combination with CaSO₄ applied in soil in winter, amino acid Ca sprayed in the first month after full bloom, and CaSO₄ applied in soil in summer. __________ Translated from Journal of Fruit Science, 2007, 24(1): 6–10 [译自: 果树学报]
