均匀电场对池沸腾换热的影响分析

对均匀高压电场作用下平板池沸腾换热的强化效果进行了试验研究,发现在较低过热度的范围内电场对换热有明显的强化效果.场强越高,相同过热度对应的换热系数越高.在相同的场强下,强化系数随着热流密度的增加而减少.结合试验结果对电场强化沸腾换热的机制进行了分析.在热流密度较小的范围内,对流换热占主导地位,电场强化对流换热使壁面过热度大大下降,导致相应过热度下汽泡的平衡半径提高,因此,抑制了核态沸腾.随着热流密度的提高,汽泡的产生和运动成为影响换热的主要因素,此时过热度的变化不是很大,在相同的过热度下,电场可以减小汽泡的临界半径,使汽泡增多.在汽泡准备区,电场会影响汽泡的核化;在汽泡成长区,电场会影响汽泡的长大、变形和脱离;在非沸腾区,电场会影响单相流体的自然对流换热.

Mitchell's Relational Conflict Model: An Analysis of Its Usefulness in Clinical Social Work

This article examines the relational conflict model developed by Stephen A. Mitchell. The main concepts of Mitchell's relational conflict model are discussed, particularly early patterns of connection to parental figures and the interactive treatment approach to understanding and changing those relational patterns. The model is contrasted with classical drive and developmental arrest theories in the psychodynamic treatment of psychopathology. We explain how Mitchell's model, in keeping with a social work perspective, takes into consideration the social, cultural, and environmental factors as well as the intrapsychic. We discuss how patterns of relating are reworked throughout the life course, and we explore the potential for individual agency in constructing new patterns of relating. We also highlight the social constructivist aspects of Mitchell's approach which are congruent with current contemporary trends in social work theory. A case vignette is presented to illustrate the viability of this model for clinical social work practice.

Treatment outcomes among adolescents with substance abuse problems: the relationship between comorbidities and post-treatment substance involvement

This study examines comorbid mental disorders in relation to post-treatment outcomes (12 months post-intake) among adolescents (N=419) who entered three residential drug treatment programs. When contrasted with youths who had no comorbid mental disorders or youths with a single comorbid condition, those with combined internalizing and externalizing disorders (mixed comorbidity) had higher levels of substance-related problems and poly-drug use at entry to treatment, and poorer outcomes, e.g. relapse, particularly evident for drugs other than alcohol or marijuana. A significantly higher proportion of those with mixed comorbidity were admitted to short term residential treatment, as compared to long term residential care. However, the effects of comorbidity were independent of both planned and actual length of stay, suggesting that comorbidities can negatively impact treatment outcome in multiple ways, apart from length of stay. Since co-occurring problems appear to profoundly limit treatment effectiveness, treatment strategies that address comorbidity are needed to improve outcomes.

企业合并会计处理方法的比较

企业合并是指一个企业与另一个企业的联合或获得对另一个企业净资产和经营活动的控制权,将各单独的企业组成一个经济实体。企业合并主要有购买性质的合并、股权联合性质的合并,会计处理方法相应地有购买法和权益结合法。对两种会计处理方法进行比较,便可知其存在的利弊。
