简介：是选择马力强劲的运动型汽车，还是选择节能环保的混合燃料汽车，这是人们买车时经常要考虑的问题。不过在不久的将来人们就不用为这些操心了，因为既环保又出速度的汽车发动机即将问世了。

简介：据悉，一种以“燃气发动机热泵”作驱动的空调已由上海交大研制成功，这台具有完全自主知识产权的“天然气空调”样机已通过验收。按照上海市政局计划，今年年内要在全市推广这种“气食性”空调至少150台。

简介：采用神经网络来辨识汽车发动机的有关歧气管压力环节的非线性动态模型,为实现系统的非线性动态映射,引入了外部回归项,然后用动态Levenberg-marquardt算法来对动态模型进行参数估计.仿真结果表明,基于神经网络的模型具有较高的精度和较强的通用性.在此基础上,用动态增益矩阵法的故障诊断方法和神经网络实现汽车发动机的在线故障诊断.

简介：断路器的发展主要体现在断路技术的发展和新绝缘材料的应用上。在20世纪50-70年代，应用较多的是油断路器和空气断路器。70年代后，主要采用SF6断路器，该断路器绝缘性能好，结构相对简单，因而得到了广泛推广与应用。在过去的几十年里，随着材料科学的进步，SFS断路器的可靠性有

简介：对特定的性能参数（如效率）进行优化时，其他参数总是要作一些调整。本文目的是对决定电动机可靠性的各种性能参数和要素进行比较。除了电动机耐用性外，还考虑了对电动机寿命的影响。本文仅对根据1992年能源法生产的三相笼型感应电动机与普通电动机进行比较。
