基于RT-LAB的混动车BMS硬件在环测试系统

针对混动车电池管理系统(BMS)开发了硬件在环试测试平台。该试测试平台硬件包括实时仿真机、电池模拟器、故障注入设备等,软件包括电池及整车实时模型、RT-LAB实时仿真平台、PROVEtech:TA整车标定软件等。采用该HIL平台进行了BMS技术指标测试、功能测试、不同路况下的逻辑测试。结果表明:该硬件在环可以快速、准确、全面地验证BMS的性能参数、控制逻辑及与整车的交互能力,大幅缩短产品开发时间和开发成本。

TK-G型液体土壤固化剂的研制及其固化机理

采用单因素对比方法研究阴离子表面活性剂、多元醇、二乙醇胺3种材料对土壤固化剂性能的影响,分析3种材料在不同用量时对土壤固化剂的凝结时间影响系数比、无侧限抗压强度比和水稳系数比3项性能指标的影响规律;并采用微观测试手段对其作用机理作了分析。结果表明:研制的土壤固化剂其凝结时间影响系数比为109. 2%,无侧限抗压强度比为140. 1%,水稳系数比为117. 7%,满足相关规范要求并对北京地区的黏性细粒土有良好的固化效果。

Rapid Determination of Silicon Content in Rice

A method for rapid determination of silicon content in rice was introduced. The reliability of this method was verified by using a recombinant inbred line （RIL） population of rice cross Zhenshan 97B / Milyang 46. Two hundred and forty-nine RILs were transplanted in two replications. Simple correlation coefficients on the silicon content in the hull, flag leaf and stern in rice between duplicate samples of 498 rice materials were 0.97954, 0.97026 and 0.98848, respectively. Ten representative samples were selected for measurement using the high-temperature alkaline fusion method. Simple correlation coefficient between the silicon contents determined by the high-temperature alkaline fusion method and by the present method is 0.9993.
