Experiment Research on Leachate Treatment of Sanitary Landfill for Municipal Solid Waste     

WANG Li ao  GU Heng yue 《保鲜与加工》2002,(2):99-102

It is difficult to treat landfill leachate in China.Traditional biologic method and physical method always have high expenses,or cann''t reach the discharge standards.The authors use a new biologic method to treat landfill leachate,which is the Wood_microbial System from Japan.The system to be digested by 3 aeration tanks and 1 reaction tank.The comparison combine processed wool_dust broken pieces with the certain grain degree size were throw in the tanks.Dirty and organic matter are in the digest tanks through the aeration reaction and aneration reaction repeatedly.In this experiment the speed of wastewater discharge and oxygen supply has been changed, and the change of biologic system and the effect of pollutant are removed. The optimal treatment condition can be found.The experiment shows that the system has a good result,special for nitrogenous.The BOD is average to do away with the rate to amount to 90%,almost reach the second class or third class for leachate standard.But BOD loading should be not beyond 4 kg/(m 3.d),othrwise,the system will not operate in normally.  相似文献   

Model of Information Integrating in CIMS Based on the Object-oriented Method     

HUANG Min  HUANG Xi yue  MA Xiao xiao  NI Lin 《保鲜与加工》2002,(4):51-54

Information integrating is the most important key to CIMS,which is the base of the function integrating and all others.Because of so many kinds,so complicated structure,so many different sources and uses that the information in CIMS has,it is necessary to build a popular Information Integrating Model. The model of information integrating in the thesis bases on the enterprise model,which is presented by ISO(International Organization for Standardization).According to the object-oriented method,the process of modeling begins with classifying the information,and then describes the definition of the attributes and the structural relation of those objects. By means of the idea of Encapsulation and Inheritance,the destination of information integrating can be arrive and the model of information integrating can be set up. The model which is based on the share information is helpful to finish the function integrating and the whole CIMS' construction. Moreover,the system which is developed following such program can be reused for many times and the developing circle of CIMS can be apparently shortened,too.  相似文献   

A Research on the Way of EMBET in the Tracking Systems'' Accuracy-analysis During Satellite Launch     

GAO Bo  HUANG Xi yue  YU Wang qing  CHE Zhu ming 《保鲜与加工》2002,(1):88-91

In the past, the criterion for calibration has almost invariably been the stellar oriented ballistic camera,the method is a point to point comparison on the identical coordinate system. Deficiencies is follows: The request of weather is severe(cloudless night); The period is often long; the measure equipment of high precision can't be calibrated. While EMBET methods is used in calibration, it does not need criterion and it demands only that the measure elements is larger than 3,and the trajectory and many system errors of the measure elements can be simultaneously calculated with the measure data sequences. The error models of related equipments' measure elements and the EMBET of typical equipment group are given. The EMBET method is successfully used in Accuracy-analysis of Satellite Launch.  相似文献   

Automatic Fingerprint Classification by GA-Based Neural Network     

HUANG Xi yue  MA Xiao xiao  SHEN Zhi xi  WANG Peng  ZHOU Xin 《保鲜与加工》2001,(1):74-77

Fingerprint classification can provide an important indexing mechanism in a fingerprint database. An accurate and consistent classification can greatly reduce fingerprint matching time for large database. In the paper, by combining genetic algorithm and neural network is presented a fingerprint classification algorithm which is able to achieve an accurate classification. By inputting the global feature represented by directional image to three layer neural network trained by genetic algorithm, the fingerprints were classified into six categories: whorl, right loop, left loop, arch, double loop and undiscerning type successfully.  相似文献   

Internet Telerobotics and Its Applications     

HUANG Xi yue  MA Li bo  HE Chuan jiang  CHEN Dong yi 《保鲜与加工》2002,(9):50-54

According to a new trend of telerobot control, some key techniues are researched to solve the Internet telerobotics , such as distributed intelligent computation on the Internet, human-computer interface,and Internet-robot interface etc.The current development status of the Internet telerobotics is reviewed. Based on the new directions of the network software development, the authors discuss that the middleware technique CORBA plays an important role in solving the problems of the Internet telerobotics,and it is an effective way to use Java language to control the telerobot and improve its system performance. The application perspective of the Internet telerobotics is investigated.It is indicated that the development trend of the telerobot control is a human-centred collaboration mechanism of mutual reinforce and coordination in human-machine intelligent.  相似文献

唐世银  张可越 《安徽农业大学学报》2002,(4):60-62

国际合同是国际交易的主要形式，由于国际贸易的自由化，为与国际接轨，应扩大国际合同的主体范围。当事人共同选择的法律、与合同有最密切联系的法律和国际统一实体法是解决国际合同争端的主要法律依据。由于先决问题的存在，还会涉及到多个法律的适用。  相似文献
