1.论文英文摘要怎么写Non steady state method for determination of thermal properties of materials has become the main means, transient plane heat source method has short test time, can obtain a plurality of thermal parameters and other prominent features. In this paper, transient plane heat source method for measuring thermal conductivity of insulation materials carries out the theoretical analysis and testing technology research.This paper derives the transient plane heat source method for ideal test model of thermal parameters, sensitivity analysis, according to the parameters of sensitivity to determine their estimates of the likelihood of, according to the theoretical model to calculate the physical parameters of the theoretical value, in order to test the improved Gauss method to estimate the parameters of the feasibility and accuracy of. Sensitivity analysis shows that by the heating surface temperature rise curve can be determined by the material heat storage coefficient, temperature rise curve within the specimen can be estimated at the same time heat conduction coefficient and thermal diffusion coefficient.Carry out 3D simulation, verified the system satisfies the one-dimensional heat transfer hypothesis, the test sample in the Z direction to meet the semi-infinite hypothesis, and the initial temperature non uniformity and environmental temperature were made by ANSYS numerical simulation, and the simulation results by the method of parameter estimation of thermal conductivity and the obtained theoretical model comparison, thereby to judge error.Developed insulation material Transient plane heat source method for thermal conductivity test technology standards, including the method principle, device, selection of heating power, sample size design and effective testing time. 。
2.关于论文摘要的英文版16 session of Fifth Plenary Session pointed out that, the construction socialism new countryside is in our country modernization advancement significant duty.Only then speeds up the construction socialism new countryside, can as scheduled realize the comprehensive construction well-off society and the modernized powerful nation grand goal.In which economic agent decision socialism new rural reconstruction success or failure.Has carried on the investigation to the current rural economy development, manifests following present situation.Agricultural structure contradictory still prominent, the industrial production degree is not high; The village level debt bears heavily, restricts the economical development seriously; The agricultural capital rises in prices excessively quickly, alleviated the advancement which the farmer becomes rich; Works the output overall quality to be low, the employment additionally receives ability not to be strong; The country shifts the payment not to be able the full amount arriving, the countryside society enterprise to invest the insufficiency.Has conducted the research to these questions, may take the following countermeasure measure.Speeds up the agricultural structure adjustment step, the advancement agriculture industrial production advancement; Enlarge attract/bid for/invite investments dynamics, advancement industrialization advancement; The force advancement urbanization, speeds up the city and countryside integration advancement; Speeds up the agricultural surplus-labor the shift, cultivates the new economical point of growth; Carries out central in countryside each policy, the promotion economy development, the farmer additionally receives.
Key words: New countryside; Economic agent; Agricultural structure; Additionally receiving
3.论文中的英文摘要怎么写English Abstract and Keywords Breathe in life are no longer unusual for normal motion, and breathing or panting通俗地说more for the purpose are necessary and sufficient to itch and purifying the blood and put the blood into the lungs breath air action or procedures, as well as the subsequent breath. Similarly, the breathing in Singing is also a normal and usual action can no longer, but the singing of breath and breathing life is different from singing for a very important role. Singing breathing, there are divergent views can not see because of flavor or touched, we can only be understood from the feeling on. Singing in the respiratory conservation and efficient use must follow the principle that the respiratory control. To learn how to control breathing and respiratory control rather than singers. Breathing singing good or bad directly affects the whole. Breathing from the living, but with the life of the great difference between breathing, therefore, to breathe for singing are the cause must be part of their training at the same time, is also singing the foundation can continue. Key words: singing breathing; respiratory applications; control; art songs; arias 。
