Computer Supported Collaboration Design (CSCD) is one of the product development technologies, which is based on computer network and is attended by different experts, and which focuses on product performances.
This paper expounds the product performances and working principles of HDC series energy-saving controller of the heating system, through the analysis on the energy-saving benefit, economic benefit and the safety of this product, holds that the energy-saving controller of the heating system possesses certain prospect of popularization and application.
(5) Giving the power toothbrush customization system as an instance, this paper finally introduces the application of PDM technique, product developing technique based on product family, modularization design technique and remote product performances analysis technique in the instance system.
(3) Based on the discussion of the architecture and decomposing of the customization system, this paper studies function requirements of each subsystem, letting three-dimensional visualization, product cooperative customization, product performances analysis and or so as instances.
(4) Based on the analysis of the function requirements of product customization system, it discusses the realizing theories and methods of these functions, which include the three-dimensional visualization, function of product cooperative customization, analysis of product performances and product data management, etc.
The effect of reaction conditions on product performances was studied. As a result, the optimum conditions were as follows:n(chitosan)∶n(quaternary ammonium chloroacetate)=1∶3, reaction temperature was 90℃ and reaction time was 5 hours. The product yield of 99% could be reached.
Robust design ensures product performances to be insensitive to various uncertainties and therefore results in high quality and productivity.
Up until now, the spatial dimension of growth was not considered crucial information in forecasting new product performances.
After it successful development, "782" Cement Accelerator had sequently received the rewards both from the Department of Metallurgy Ministry and National Scientific - Technical Commission. Afterward it was soon tronsferred to industrial production.With the cooperation between the researchers and manufacture, it's production process had been improved, resulting in fur -tuer upgrading in its product quality. The paper gives a penera introduction to the modifred flowsheets and product performance.
How to realize the best economics under the condition that the product performance meets the specified requirements? It's the key to applying VALUE ENGINEERING at the very beginning of the product, design. Several methods of analyzing of product value are introduced, taking the design of oilfield equipment for example.
The paper records and narrales in detail the results from systematic observation on the behavior of wool rabbit. The actions of wool rabbit were more in the nighttime than in the daytime. So,the intake, drinking and the. amounts of feces and urination on wool rabbit were higher in the nighttime than in the daytime, and on those there were obvious varieties in seasons In winter the intake and the drinking during the night were respectively 60.88±9.32% and 62.98±6.43% of ones in all day and night,...
The paper records and narrales in detail the results from systematic observation on the behavior of wool rabbit. The actions of wool rabbit were more in the nighttime than in the daytime. So,the intake, drinking and the. amounts of feces and urination on wool rabbit were higher in the nighttime than in the daytime, and on those there were obvious varieties in seasons In winter the intake and the drinking during the night were respectively 60.88±9.32% and 62.98±6.43% of ones in all day and night, and in summer were 70.96±5.31% and 69.45±6.35%. But the mean intake in summer was only 47.23% of that in winter. Therefore, the drinking in hot season, which was little higher than in winter, approached one in cold season. While the coprophogia of wool rabbit was not often found. In winter the amounts of feces and urination in nighttime were respectively 66.23±10.1% and 62.94±8.66% of ones of all day and night, but in summer were 75.91±1.8% and 72.56±6,24%. Various behaviors of wool rabbit were effected by environmental conditions,especially by environmental temperature. Under bad environment, the actions of physiology and the expressions of behavior of wool rabbit were disturbed, which made its product performance fall. For example, on the twentieth day after partus every female rabbit＇s milk yield in winter increased by 4.4% as compared with that in summer, on the thirtieth day after partus by 8.3% and on the fortieth day after partus by 11.2%. The rate of growth on young rabbit from birth to 20 days old had not great difference between winter and summer. But, from 20 to 30 days old young rabbit＇s daily gain was 15.37 grams in summer, and 17.77 grams in winter.While, from 30 to 40 days old daily gain was 14.41 grams in summer, and 26.41 grams in winter. This variation was statistically very evident (P<0.01). The result of experiment showed the female rabbit＇s milk yield reached the highest point on the twentieth day after partus, and decreased rapidly e thirtieth day. Through observation on the behavior of wool rabbit the beneficial revelation and knowledge which were concerned in relative problem between wool rabbit＇s raise and manage and variation of behavior or physiology had been obtained in theory and practical production. So, further understanding the knowledge in physiology and behavior science is necessary. It will have very important significence for making out productive measure at high efficiency.
