Reuolution and Research of Green Automobile

The green is as a symbol of no pollution,no public harm and environmental protection. The green automobile is the inevitable results that the automobile technique continuously developes. A new style vehicle--the green automobile is the urgent solicit of environmental protection is developed. The automobile industry can develop continuously. This article mainly discusses the importance of the green auto_mobile's research and development,the development status in quo and prospect of the green auto_mobile technique in the world,and states the relationship between the green automobile technique and environmental protection from green technical system theoretically clarify the study of green automobile,including its design and the system,the manufacture and its technology,the energy,the rebuild engineering and a series of subjects. How to evaluate the cycle and the evaluable mark of the green automobile,the prospect of green automobile are pointed out.     

A Receiving Surface of Perturbative Photon Fluxes in Interaction Between Gravitational Waves and EM Fields

According to Electrodynamics in curved spacetime, the interaction between gravitational waves (GW) and electromagnetic (EM) fields will produce perturbative electromagnetic fields. In a special EM system, namely, a Gaussian beam (Gb) propagating through a static magnetic field, the photon flux along the direction of the electric field of the Gb will be only a pure perturbative photon flux,when a GW propagates along the symmetric axis of a Gaussian beam. Detailed alanysis and calculation of the photon flux along several typical surfaces are performed, and a possible optimum plane which can receive perturbative photons up to 10~4s~(-1) is proposed. It is possible to provide an important method to detection of GW.     

THE APPLICATION OF SAND-GRAVEL-CUSHION TECHNIOUE IN THE FOUNDATION OF MOUNTAINOUS AREA

This paper presents the application of sand-gravel-cushion technique in thefoundation of mountainous area inhomogeneity and analyges non-uniformity of the foundation inmountainous,It is different from the traditional theory of sand-cushion,This is a new developmentand able to make a full use of the rock debris fill and the combinational soil-rock foundation in the mountainous areas.     

A Muti-Objective Network Planning Model for Project

Based on the network planning model developed by the author for an overhaul project of a rolling mill production line in a heavy steel plant, an new multiobjective network planning model is proposed in this paper. The formulations of network time parameters are derived. The optimization problem of multiobjective network planning is also discussed. And it has been found out that the fractional single-objctive network is only one of the cases in this model.

Study on Genetic Fingerprinting Technique of Microbial Communities

The 99% of all microorganisms in naturecannot be isolated by standard culture methods without conspicuous external characters to classify them morphologically. In addition, classification based on physiological or biochemical features are often fuzzy. Molecular techniques are used for uncultured microorganisms to explore the diversity of microbial communities and novel resources without the need of cultivation. DNA dynamics and cloning of PCR products obtained from environmental DNA is now routinely used to identify microbial populations in microbial ecology. For practical reasons the approach is not suited to study the complex dynamics of microbial communities in environment. Genetic fingerprinting techniques are better tools, which give complement for the traditional microbiological methods. The methods are rapid and relatively easy to perform, and they allow the simultaneous analysis of multiple samples, which makes it possible to compare the genetic diversity of microbial communities from different habitats, or to study the behaviour of individual communities over time.     

The Dynamic Change of Soil Microorganism and Enzyme Activity in the Whole Procreative Process of the Tarim Island Cotton

对塔里木海岛棉生育全程土壤微生物与酶活性的动态变化进行了检测,测试结果表明：（1）塔河种业高产海岛棉田土壤养分比塔河滩地高出6.58%~37.42%,特别是全钾、速效钾比塔河滩地高出29.02%~37.42%。（2）微生物数量变化呈现如下变化趋势：细菌类群在夏季有生长高峰,秋季略有回升;真菌在春季存在生长高峰,夏季处于低谷,秋季生物活性开始回升;放线菌生长高峰位于夏季,春秋季处于低谷。在土壤微生物区系构成中,细菌占据绝对优势,暗示土壤养分的转化主要靠细菌完成。（3）塔河种业高产海岛棉田土壤酶中的过氧化氢酶、     

棉花烂铃空间格局及抽样技术研究

本文通过聚集度指标（如：Ｃ、Ｋ、Ｃ＿Ａ、Ｉ、Ｉ＿δ、）测定，以及Ｉｗａｏ’线性回归、Ｔａｙｌｏｒ’ｓＳ￣２一回归和格局纹理分析，结果表明，棉花烂铃空间格而在一切密度下都呈聚集型，且聚集强度随烂铃密度的升高而增加，其空间格局的基本成分是疏松的个体群，其大小约为２～５株棉花，平均约含２．８４个烂铃个体，且个体群内的个体呈随机分布，经μ检验和方差分析，双对角线５点式、棋盘式和平行跳跃式等３种取样方法均适用于棉花烂铃田间调查，尤以双对角线５点式为佳，用双对角线５点式应样法调查的最适抽样数：一般病情普查至少１０个样方（每样方系５株棉花），系统测报和科研调查为２０～３０个样方。最后给出了棉花烂铃平均密度的零频率简易估计模型。
