balance experiment
3.In this paper, a detachment-integration stack with active area of 390 cm2 was assembled for experimental studies of quantifying water balance of Nafion 112 membrane in various operating conditions. The effects of current density, temperature, pressure, dry gases operation and hydrogen stoichiometry on net water transfer coefficient were revealed. The water balance data in the paper were important experiment foundation for design of self-humidifying operation for PEM fuel cells.
4.The requirement of energy and protein as well as the utilization efficiency of metabolism energy in growing fox were studied with combination of respiratory,N C balance, degistive metabolism, analysis of carcass composition and feeding experiment. The processing procedure of mixed feed and new techniques of feed formulation were developed.
5.In visible experiment, the time of pressure balance decrease with the initial pressure of PRZ and temperature of CMT.
6.Firstly, mechanism of boundary heat transfer between solids is explained; Secondly, others research and method of build-up experiment are introduced, and the process and characteristic of boundary heat transfer between celeron 300 CPU and aluminium coolinger are analyzed, and a particular method based on thermal balance principle for measuring CPU chip thermal power and temperature collection system is introduced, and experiment process are explained in detail.
7.4×4 Latin Square experiment by using 4 hybrid male growing pigs((40.5±1.0)kg, Duroc×Landrace) was conducted with balance trail to assess the contents of digestible phosphorus in high oil corn, corn gluten meal and cotton seed meal.
8.The experiment shows that, when alu- minium chloride and waste liquid are mixed up for over 30 seconds and then butanol is added ,the PH value of mixed liquid is about 5 and about 3.5 at balance, which mixed with waste water, will have a better demulsification effect.
9.MATERIALS: The experiment was carried out in the Shandong Key Laboratory for Biopharmaceutics, Shandong Institute of Biopharmaceutics from February 2003 to January 2004. Experimental instrument: Mettler AE240 electronic analytical balance and ZK-40AB electrothermal vacuum drying oven were provided by Mettler-Toledo Instruments Co. , Ltd.
10.On rainfed upland, rainfed lowland and irrigated paddy field sites in the Philippines, the rice-based cropping patterns of farmer and experiment were researched and the evaluation from perspectives of energy balance and benefit of energy input for various cropping patterns was made.
