目的:通过对比心理咨询中4例好效果案例和4例坏效果案例同化水平的差异,对同化模型有关成功治疗改变过程的理论构想进行检验,并寻找区分好坏案例的关键点。方法:选用7位经过培训的评定者组成三个研究小组,采用同化分析这一用来追踪当事人问题经验发展进程的研究方法,对8个当事人完整的咨询逐字稿资料进行分析,并对涉及当事人问题经验的段落进行摘录。依据同化问题经验量表和同化标识手册对摘录的段落进行同化评定。结果:8个案例的核心问题得到一致确定,三组评定者评分的组内相关系数ICC(1, 1)在.64~.86之间,ICC(1, K)在.84~.96之间。好效果案例结束时的同化水平均分(M= 5.50)和同化进展均分(M= ...

Based on harmonic wave superimposing method and Kaimal spectral, the time history of fluctuating wind in open site was generated and then used as the velocity inlet for CFD flow field simulation. Fluctuating wind field and raindrops were respectively simulated by detached eddy model and discrete phase model. Using wind-rain coupling CFD model, hitting velocity and time of raindrops at different heights of transmission towers can be obtained. According to the impulse theorem and the impulse equivalence principle, a method for calculating rain load averaged over any time interval was proposed. T...
