冶金多相反应器内分散相在湍流连续相中的运动特性研究

文章以冶金多相反应器内的分散相为研究对象,分析了分散相产生的条件及其在湍流连续相中的运动特性。研究结果表明：经适当假设后,分散相在连续相中的运动可由一阶线性方程描述;湍流反应器内分散相的数量、尺度影响其在连续相中的分布,其数量越多,尺度越大,则分布越不均匀;当分散相与连续相扩散系数相同时,它们之间的运动没有滞后,利于渣-金间的混合。应用现有湍流研究成果可以为优化此类反应器的工艺参数提供有益的参考。

KCI-CsBr-CaBr2相图的研究

A computer prediction for the regularities of formation of binary bromide system was made. The results indicate that CsBr-CaBr2 molten salt system is binary complex compound-forming system. The phase diagram of CsBr-CaBr2 system has been determined by visual polythermal method in order to prove the prediction. The phase diagrams of the quasibinary system KCl-CsBr, KC1-CaBr2 and the quasiternary system CsBr-CaBr2-KC1 were determined by using visual polythermal method. The phase diagrams of CsBr-CaBr2 and KCl-CaBr2 show that the intermediate compound is formed. The results are in agreement with the computer prediction. Here, the various parts of the phase diagram of the quasiternary system CsBr-CaBr2-KCl were discussed.

The Stimulation Phase in Counseling

The evolution of a general model of counseling from Rogers through Carkhuff to Egan has resulted in a loss of emphasis on perceptual change and an increasing interest in social influence and action interventions. Greenberg and Kahn present an expanded model of counseling, which includes a stimulation phase. The addition of a stimulation phase in counseling is suggested to provide a place for active counseling methods that effect client perceptual change. This stimulation phase actively involves the counselor and client in full exploration, which culminates in discovery. Two processes are differentiated: discovery and dynamic self-understanding. Active stimulation leads to new awareness that can be enhanced by social influence to achieve new understanding.

Simulation of Automotive Engine Phase Signal Based on Closed-Loop Strategy

In this paper, an automotive engine phase signal simulation algorithm is proposed based on a closed-loop feedback strategy, and its corresponding model is built. The signal incentives are carried out in the front-end, and the synchronization capture and comparison are conducted in the back-end. The phase simulation of signal output is achieved using closed-loop strategy, which can effectively eliminate the inconsistency between crankshaft and camshaft phases, and thus the accuracy and flexibility of phase signal generation are guaranteed. Experimental results show that the proposed algorithm is real time, and the deviation of simulated signals from actual phase signals is small.
