高原条件 meaning in Chinese
high conditions
Examples
- With this turbocharger on high altitude area , the power of diesel engine need not be modified or less modified , which meets the charging need of the diesel locomotive in the west plateau condition in china
特别是在高原地带，装用这种增压器后，能使柴油机功率少修正或不修正，较好地满足了铁路内燃机车在西部高原条件下的增压需要。 - This new technology changes from the traditional method by which the induced and compressor wheel separately are designed and produced to a new one by which the one - piece compressor is designed . on the basis of this new technology and the optimum blade profile , the performance of both the compressor and the turbocharger is largely improved . through the heating power calculation of the compressor , the analysis of the surge and the block of the compressor , the test - bed performance test of the turbocharger , the matching test of turbocharger and diesel engine , the propulsion test of the turbocharger on plateau condition , it is proved that the newly - designed compressor not only has high efficiency , but also improves the flow distribution in the high efficiency area so that the propulsion line can run through the high efficiency area
主要内容包括：提出一种全新的压气机叶轮技术和概念，这种技术将传统的导风轮和压气机分开设计、单独加工改为整体设计、整体加工的单体叶轮；从增压器与柴油机配机计算所得出的基本参数出发，通过对压气机进行热力计算，确定压气机的基本结构参数；再对叶型以及叶轮轮廓与叶轮罩壳的配合间隙进行优化，对新设计的压气机进行喘振和堵塞分析；通过增压器平台性能试验，验证了新设计的压气机的性能水平得到了较大的提高，达到了提高增压器的整体性能水平的目的；通过增压器与柴油机配机试验、以及增压器用于高原条件下的牵引试验，验证了新设计的压气机不但具有高效率，还改善了高效率区的流量分布，使牵引特性线贯穿高效率区。
