, 1985 本文研究了正交铺层([0/90]s)碳纤维增强环氧复合材料在静态与拉—拉疲劳下的损伤破坏,探讨了它的破坏机理。通过采用显微观测,声发射技术及红外热象分析等多种手段测试其力学性能、损伤的产生和扩展,得到了不同加载条件下材料微结构的损伤断裂与声发射表征量及温度变化的关系。声发射累积量的突然增大可预报材料的断裂 ...

, 2003 利用高压容积法、辅以卸压升温脱附排水法,测定金属钾修饰多壁碳纳米管(K~0-MWCNTs)对H_2的吸附储存容量。结果表明,在室温(～25℃)、～7.25MPa实验条件下其对氢的吸附储存容量可达3.80％(质量百分数);室温下卸至常压的脱附氢量为3.36％(占总吸附氢量的～89％),后续升温(升至673K)的脱附氢量为0.41％(占总吸附氢量的～11％)

Gaoya dianqi不同频率运行工况下，频率显著影响了中压开关柜的电磁场分布与温升特性，仅依据工频标准难以准确评估不同频率下的设备运行状态及载流能力。为探究频率变化对开关柜的电磁—热的影响规律并量化其载流能力，文中以KYN44-12（Z）开关柜为研究对象，搭建了基于交流—直流—交流的宽频域温升试验平台，建立了电磁—流体—温度场耦合模型。在此基础上，开展了16.7～60 Hz频率下的温升试验与仿真研究，验证了模型的准确性。研究发现，频率变化显著影响导体电流的趋肤效应与邻近效应强度，导电回路的电磁损耗与频率呈线性正相关 ...
