Pop sociology and the psychotherapist.

Suggests that G. W. Albee (see record 1977-29846-001) holds a model of a psychotherapist as one who loosens inhibitions and frees sensuality. It is suggested that psychotherapy actually attempts to integrate all impulses and realities within a value or philosophic context, not a context of hedonistic sensuality.

Investigation of heat transfer and pressure drop for a multiple-started ribbed pipe using large-eddy simulation

Turbulent heat transport phenomena in multiple-started helically ribbed pipes are investigated. Such structures are applied to enhance heat transfer in various technical systems. A large-eddy simulation (LES) approach is used to model the turbulent flow field. The simulation results for heat transfer and pressure loss are in good agreement with available experimental data and the simulation model is successfully validated for complex surface geometries. For a better understanding of the impact of the wall structures on the turbulent transport processes, local profiles of the relevant flow variables values are investigated. Thus, the specific mechanism of the heat transfer enhancement can be explained and a knowledge-based optimization of innovative structures is possible.     

用小能量多冲击法测量烧结钢的断裂韧性

采用小能量多次冲击法测量了尺寸为12mm×12.5mm×62.5mm烧结碳钢的断裂韧性K_IC值。考察了碳含量、冷却速度及后续退火工艺对粉末烧结钢的断裂韧性K_IC值的影响。结果表明,烧结钢在小能多次冲击状态下的断裂韧性K_IC值主要由烧结钢的强度决定。同时也需要一定的塑性与之相配合。     

THERMAL CRACK AND WEAR OF RAIL WHEEL AND DEVELOPMENT OF THERMAL CRACKING PROOF WHEELS

The thermal cracking and wear mechanism of rail wheel tread have been studied.The resultsshowed that the thermal cracking of rail wheel tread is related to the chemical composition(mainly the carbon content)and the hardness of the wheels.When the composite brakingshoes are used,the rate of wear of the wheel tread is related to the fracture toughness of thenewly-formed“white layer”i.e.the martensite.The thermal cracking proof wheels(55SiMn)so far developed has achieved significant operating results in practical use.     

华龙一号应急工况评价系统初步开发

为了满足华龙一号(HPR1000)事故条件下的应急响应,需要开发一套应急工况评价系统,用于基于征兆的堆芯损伤评价和释放源项估算。本文给出了华龙一号应急工况评价系统(ECAS-HPR1000)的总体设计,包括软件框架、评价模块、平台和接口开发等,该系统采用跨平台的JAVA语言开发,以MySQL数据库作为数据存储,支持Windows 和Linux操作系统。该系统包括五个子系统,分别是基础数据采集和管理子系统、堆芯损伤评价子系统、释放源项计算子系统、评价结果展示子系统和用户权限管理子系统。该系统可以基于实时工况数据,评价堆芯损伤状态和程度,并计算出堆芯释放到一回路、安全壳和环境的放射性核素的量,并考虑了华龙一号双层安全壳对计算结果的影响。     

土壤氡测量在塔拉乌苏地区砂岩型铀矿勘查中的应用

塔拉乌苏地区是巴音塔拉凹陷中北部重要的铀成矿远景区。为评价研究区砂岩型铀矿找矿前景,本次采用RaA法、活性炭法等综合放射性测量技术在该地区进行土壤氡浓度测量,以此划分出土壤氡浓度异常分布范围。结果显示,区内存在DQ-1、DQ-2和DQ-3等3片异常区,经后期钻探查证,已发现铀矿化特征,反映该地区铀成矿潜力较大,认为在DQ-1与DQ-2异常区的夹持部位,为有利成矿预测区,具有良好的找矿前景。

后处理厂1A柱有机相着火事故源项估算

我国对于后处理工业的需求随着核电事业的迅猛发展变得愈发强烈,为了满足后处理工业安全发展必不可少的核应急需求,为核应急工况下后处理厂的核应急响应与决策支持提供依据。针对后处理厂1A柱有机相着火事故这一基准事故,结合实际工艺流程及监测手段,选取了核应急工况下的可获得参数(有机溶剂泄漏质量等)作为输入,在有机相燃烧速率经验公式基础上,结合后处理的工艺特点,引入少量修正建立了后处理厂1A柱有机相着火事故源项估算模型,并使用FORTRAN编程语言开发了相应软件。数值验证结果表明,该估算模型可以满足后处理厂1A柱有机相着火事故的核应急需求。     

水泥-尾砂充填体常规三轴压缩性能研究

由充填体常规三轴压缩强度和变形试验得到了峰荷应力和应变及相关试验曲线,对充填体三轴受压渐进破坏过程进行了描述分析。试验中看到,充填体在轴压下产生的裂缝的发展因施加围压而受到抑制,这种约束与围压成正比,即充填体破坏形式从零或低围压的脆性破坏到高围压的塑性软化流动。工程实际中,充填体多数情况下处于多轴受力状态,因此对充填材料进行多轴应力下的强度和变形行为研究具有现实意义。
