Orientation of Aim Client in Real Estate Development Based on EXCEL

In order to subdivide the market during the process of project planning and orient the group of client, then determine the sale price; on the condition that the traditional orientation procedure cant grasp the payment capability of the aim client, the anthors can adapt the powerful finance analysis ability of EXEL to design the procedure of determining the purchasing power and payments ability of the aim client, and shape a set of orientation system based on quantitative analysis method. The result is, the character of the aim client can be grasp accurately depend on this orientation system, and providing a scientific gist for the accurate orientation of price and lowing the risk of investment etc.     

Philosophy of Science and the Chinese Contemporary Architectural Forms

Philosophy of science led by Popper is one of the most important contemporary scientific and philosophic theories.In addition to the science,the philosophy of science impacted contemporary social science mostly,of which the false-feasibility,circumstantial logic,anti-historical determinism and anti-scientism influenced the orientation of contemporary architecture.Just with these factors of philosophy of science,this thesis reanalyzed and reviewed Chinese contemporary architectural forms,especially the tradition inheritance.     

Management System of the Tender and Bidding for Power Projects with a Valuation Based on the Bill of Quantities

Valuation based on the bill of quantifies will change the existing valuation mode of tender and bidding. For the standardized management of tender and bidding for power projects and the inteUigentized information management of power enterprises, it is an inevitable trend of reform to apply the valuation mode based on the bill of quantifies. According to the characteristics of power projects, this paper expounds the working process of the valuation mode based on the bill of quantities and analyzes the goal and function need of the tender and bidding management system. Considering the calculation procedure of the valuation and the quote strategy of quantities bill, the composition of fees for the valuation is settled and the calculation method is designed. To establish the management system of tender and bidding with a valuation based on the bill of quantities is beneficial for the costing reform of power projects and the perfection of the tender and bidding market. Therefore it is of great significance to spread the new management mode of project costing with a valuation based on the bill of quantities.     

冀、鲁、豫、苏、皖五省农机夏收跨区作业调研报告

农机跨区作业是我国农民自发进行的又一项伟大的制度创新,为促进我国农业机械化发展做出了重要的贡献.为此,采用问卷调查法、文献资料法和数理统计法,对冀、鲁、豫、苏、皖等省505户参与跨区作业的农机大户进行了问卷调查.以问卷数据为基础,分析了农机大户的自身特征和经营状况,并总结了影响跨农机大户参与跨区作业的主要因素,最后提出了相应的对策建议.     

BP神经网络在焉耆盆地农田排水量

利用BP神经网络技术对焉耆盆地农田排水量进行预测。利用灰色关联度分析确定了排水量与各影响因素的关系，选取了对排水量影响最大的5个因素作为BP网络的输入，利用均匀设计方法，确定了最优的神经网络结构。估算结果表明利用BP神经网络可以准确的估算农田排水量，最大相对误差仅为-2.45％。     

用计算机进行小麦赤霉病的预测预报

根据苏北某市农业局提供的十几条与小麦赤霉病有关的气象经验。用1971年以来的气象数据建立几种数学囚子模型；将数学因子与赤霉病实际发病的结果数据进行相关分析，提取相关性较好的数学因子组成相关因子；运用相关因子分别采用4种预测预报方案进行预报。     

四季秋海棠炭疽病菌生物学特性及生防因子的筛选

以四季秋海棠炭疽病菌(Colletotrichum truncatum)为试验材料,采用菌落生长法和孢子萌发法,研究了不同培养条件对四季秋海棠炭疽病菌菌落生长和孢子萌发的影响;采用生长速率法研究了14种植物提取物对四季秋海棠炭疽病菌的抑制作用,以期明确该病原菌生物学特性,筛选对其具有抑菌活性的植物提取物,为该病害的防治提供参考依据.结果 表明:最适宜该病原菌菌丝生长的温度为25～30℃,pH 7,最适碳源为葡萄糖,最适氮源为硝酸钠和甘氨酸.分生孢子萌发的最适温度是30～35℃,pH 6～7.丁香、石菖蒲、蛇床子提取物在2.0 mg·mL-1浓度下对菌丝生长具有较好的抑制作用,菌丝生长抑制率分别为100％、92％和90％,其它植物提取物抑制率在20％～85％.     

牛卵巢活动对超数排卵影响研究进展

超数排卵在实际生产中提高了胚胎移植技术对单胎动物的繁殖率,但是,超数排卵的结果存在很大的差异性。影响超数排卵结果的因素有很多,如牛的自身因素,超数排卵方法的选择,所使用促性腺激素的种类,激素的质量,环境因素等。文章以牛自身卵巢活动对超数排卵的影响为出发点,综述了牛正常卵巢活动及卵泡活动对超数排卵影响的研究进展,包括卵泡波动力学,卵泡波发育过程中促性腺激素的作用;分析了卵巢对促卵泡素(FSH)及促黄体素(LH)的特异应答性机制,对各个卵泡波进行了比较,根据卵泡波动力学理论列举了几种切实可行的同步卵泡波的超排方法,对超数排卵结果差异性的原因做了补充说明。     

代乳粉对羔羊生产性能及血液生化指标的影响

本文旨在研究代乳粉对羔羊生产性能和血液生化指标的影响,并优选出适宜的羔羊代乳粉营养水平和稀释比例。选择80只健康的小尾寒羊羔羊,采用单因子试验设计,将羔羊随机分为4组进行试验。初生羔羊吃足初乳,于5天后分组,采用逐渐替代法,将母乳转换成3种不同营养水平的代乳粉,分别以一定的稀释比例哺喂3组羔羊,另1组为对照组(喂纯羊乳)。结果表明:①饲喂代乳粉对各组羔羊的死亡率无显著影响。②试验1组的平均日增重(ADG)为193 g,明显高于对照组的151.25 g和试验3组的107 g,差异显著(P<0.05);而试验2组的平均日增重为160.5 g,与其他3组无明显差异(P>0.05)。③血液指标中,血糖(Glu)值以试验1组最高,为3.84 mmol/L,明显高于对照组和其他2组(P<0.01);试验2组的血清尿素氮(BUN)值为16.89 mg/dL,极显著地高于对照组的9.99 mg/dL和试验3组的8.76 mg/dL(P<0.01),显著高于试验1组(P<0.05);各组中血清白蛋白(ALB)含量比较接近,无显著差异(P>0.05);总蛋白(TP)含量试验1组最高为52.26 g/L,极显著高于对照组和试验3组(P<0.01),而与试验2组相比差异不显著(P>0.05)。早期断奶羔羊平均每只每日进食的消化能和粗蛋白分别为9.21 MJ、106.92 g,哺喂营养含量和稀释比例适宜的代乳粉(试验1组)能促进早期断奶羔羊的生长发育。
