查询词典 dissertation

The main content of the dissertation is designing and realizing the total scheme and frame of system software. The module of the input and output is designed by using the generally I/O of the multichannel buffered serial port to simulated the communication of I~2C bus. The Ping-Pong buffer is brought forward to resolve the problem of the data rate matching. The logic switch function is designed in the programmed logic devices. The data transmission rate is improved by using the DMA and the dual buffer mechanism. The system program self-loading is realized by the design of the self-leading program. Lastly, the dissertation analyzes the characteristic of LLL video and experimentalize with some typical image processing algorithm.

The simulative model of temperature field and stress field in concrete , Heat and moisture coupling、Parallel simulative calculation of concrete with water pipe cooling、 Parallel feedback analysis of thermal characteristic parameters, and stress intensity factor of induced joint, which are the sixty-four-dollar questions, are studied in this dissertation. The main contents of this dissertation are as follows:(1)Based on the past and current research work, the calculation theory of the transient temperature field and creep stress field of mass concrete which self temperature influence is considered is deduced. The couple effect between the temperature field and humidity field of concrete, is considered on the basis of conservation law of water and energy, and the coupled formulation which coefficient is not constant of the heat and moisture in concrete is deduced. The calculation theory and model which is theoretically strict for solution to thermal problem in concrete with water-cooling pipes are recommended.
