Some Ideas on Reconstruction of Villages inside the City

In this paper, the historical reasons of formation of the village inside the city are analyzed. It is indicated that such situation for the villages inside the city are the result of joint action of both the villagers and the government. The foundation of villages inside the city laid on the simple compensation for farmers in confiscating the rural land and lack of intelligence aids. In this paper, the ideas and measures for their reconstruction are put forward based on consideration of the reasons of their formation and difficulties in the reconstruction.     

AN APPRONTMATE CALCULATING METHOD FOR WALL PLATES OF MAN'' S DRY GAS HOLDERS

The basic equations of wall plates of MAN' S dry gas holders are derived in this paper. According to the law of cylindrical bending given by the finite element results .we derive some approximate formula calculating the deflection and stresses of the wall plates from the basic equations. Compared with the known approximate calculating method.the method car. obviously increase the percision.     

Ecological Technology Strategy-the Typologic Analysis and Research of Double-Skin Facade

As a renovation envelope, double-skin facade has the characteristics of environmental function and unique aesthetic effect. In this paper, the composition and functional characteristics of double skin facade is introduced briefly, its development history and a detailed typologic analysis combined with typical cases is reviewed. It is pointed out that the double skin facade has a bright future in 21~(st) century and the function and aesthetics are the footstone for its typologic research.     

江淮稻区不同穗型粳稻品种主要农艺和品质特性的比较分析

依据着粒密度，对江淮稻区大面积生产应用的和新近育成的36个粳稻品种(系)进行聚类分析。结果表明，供试品种可分成半密穗型(Ⅰ)、偏密穗型(Ⅱ)和密穗型（Ⅲ）三类。随着水稻品种由散穗型向半密穗型、偏密穗型和密穗型的演变，产量性状、品质性状、形态性状和部分生理、生化性状发生了明显的变化，产量、每穗总粒数和实粒数显著增加，而穗数/m²、千粒重和结实率呈下降趋势；株高增加，上部三张叶片变长、变宽，生物日产量增高；穗部一、二次枝梗数增多，着粒密度变大；抽穗期和成熟期叶片、茎秆的含氮量和叶片叶绿素含量增高；糙米率和整精米率下降、垩白粒率降低、胶稠度变硬、蛋白质含量呈上升的趋势。     

小麦异源细胞质对主要病害抗性影响的初步研究

在大田自然发病和人工诱发条件下,研究了小麦异源细胞质对条锈、叶锈、秆锈、白粉和赤霉5种主要小麦病害抗性的影响。结果表明在同核条件下,不同异源细胞质对同一病害抗(感)性的影响不同,同一种细胞质对不同病害抗(感)性的影响也不完全相同;并且在不同地区试验的结果有时也有差异。根据初步研究结果,无芒山羊草、拟斯卑尔脱山     

探讨集中式排种器的排种机理及其发展

目前传统排种器多属于“一器单行”型式。机械式对种子尺寸要求严格、破碎率高;气力式能耗大、结构复杂、使用要求高。而集中式排种器(或系统)是对“一器单行”技术的突破,满足精密播种的要求。主要论述了国内外集中式排种器的工作原理、发展概况及其存在的问题。     

基于边界层理论的叶轮的仿真

根据边界层理论推导的叶片型线方程，用pro/E建立了叶轮的三维仿真模型。该模型提供了设计离心式固液两相流泵叶轮的一种方法，通过pro/E的族表功能，只要输入叶轮的基本参数就能快速生成基于边界层理论的叶轮的模型，所以建立该模型对工业生产有一定的参考价值。     

病态池的检查和维修技术

随着沼气建设的快速发展,病态池的数量也随之增多。本文就如何分辨沼气池和输气线路病态、确定病态沼气池的病态类型、查找病态池漏水漏气部位及维修病态池提出了具体的方法。
