Tissue Culture and Rapid Propagation of Actinidia chinensis

It has been briefly studied and reported that Actinidia chinensis , one of economic woody plants, has been bred with the method of plant tissue culture. Aim at the shortage of traditional plant tissue culture ways which ignored the refinement and transplant of test-tube seedling, it strengthen the study to breeding and management of Actinidia chinensis seedlings before they grow up and become mature seedlings. Through our explore, the transplant survive rate of tissue-culture seedlings attain to about 85%.This study is the improvement to traditional breeding seedling means and it is helpful to the rapid propagation of those economic woody plants.     

Determination to Weighting Coefficient of Combination Forecast Based on Rough Set Theory

The problem of determination to weighting coefficient is a key and difficulty for combination forecast. A method of determining weighting coefficient based on rough set theory is showed in this paper. Determining weighting coefficient is translated into estimating significance of attributes among rough set. A relation data model about combination forecast is established. Knowledge systems are built through making attribute value into eigenvalue. Under data moving, the weighting coefficients of a combination forecast model are computed by analyzing the dependence and significance of forecasting method for the predicted object. The proposed approach overcomes the subjectivity of traditional determination to weighting coefficient, avoids computing linear or nonlinear extremum problem and makes combination forecast more objective. The validity of the proposed approach is verified with a case.     

Models to Separate Daily Diffuse Radiation from Daily Total Radiation for Energy Consumption Analysis of Air-Conditioning System

Both total irradiation and diffuse irradiation are necessary to building energy consumption analysis. At the most cases in China,only total irradiation is available. So some method is needed to estimate diffuse irradiation. Relationship between daily diffuse irradiation and daily total irradiation is analyzed, based on data form Beijing and Chengdu.Polynomial models for Beijing and Chengdu are established to estimate K d form K t . Validation tests show good performance of the models. Monthly means of predicted daily diffuse irradiation is not significantly different from that of the original daily diffuse irradiation. Also,the auto_correlation function of the predicted diffuse fraction, K d is coincident with that of the original K d . Beijing model can accurately predict the data of Chengdu,which is significantly different from Beijing as to the climate,so it is recommended as the general model.     

Structural Analysis and Discussion of Wide -stayed Bridge Basket

Based on a cable -stayed bridge girder as an example, the structure and function, the operating principle and calculation model of the main elements of the Basket of wide - stayed bridge were described in detail. A further discussion was carried out on the Basket of Cantilever construction of the main beam in the structure.     

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

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.     

Developing a Recognition System of Gun-code

Intelligent recognition system of gun code is designed , which achieves online recognition of gun code. We applied video camera to get image, and some special technique in this deformed character recognition. As well, we applied dynamic template matching to get a better result.     

EPQ Model with Different Lost Sale Factor Relative to Inventory Level

It is important for enterprises' inventory management to find out the optimal production cycle and the length of shortage time,so that the total cost of inventory system can be reduced and the service level can be raised.Based on the classical EPQ model,this paper develops an EPQ model for deterioration items with different lost sale factor relative to the inventory level during shortage period.The existence of unique optimal solution is discussed by mathematic analysis and a numeric example.The sensitivity analysis shows that the parameter of losing sale has different impact on the costs of inventory system.The factors must be considered for the production inventory system to make management decision.     

Application of Principal Component Analysis on Workable Competition Evaluation

The effective competition is an effective organizational form of the industry in modem market economy. It is a form accompanied with large - scale production and vigor competition. The analysis of effective competition has been the focus that people have paid close attention to it very much all the time. It is a basis of industrial policy, on the basis of the former research, the aufhors bring out 9 indexes according to the actual situation of our country, then take automobile trade as an example, we analyze the automobile trade with principal component.     

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.
