When hydroturbine generator runs in steady state,oil film stiffness and dampingcan greatly affect the unit s vertical vibration.

水轮发电机稳态运行时，油膜刚度与阻尼对机组的垂直振动有着重要影响。

Flow inside hydroturbine has great influences on its energy characteristics as well as unit stability. In particular, the vortex in the draft tube is an important factor which affects unit stability. Therfore, the research of flow in the hydraulic draft tube is continuouly receiving everbodys attention.

水轮机内部流动，不仅对其能量特性有重要影响，对机组的稳定性也有严重的影响，尤其是尾水管内的旋涡流动更是引起机组稳定性的重要因素，因此，水轮机尾水管内的流动研究一直受到大家的重视。

The results of saline water irrigation (1990~1995) showed that the yields of wheat, corn, cotton and grain increased 30% more than those of non-irrigated crops. In the condition of spring irrigation and concentrated rainfall, the soil desalinized in root zone, and the accumulated salt due to saline water irrigation can be leached; reasonab...

三坝浅层地下咸水灌溉试验( 1 990～ 1 995)的研究结果表明，利用 3.0～ 5.1 g/ l的咸水灌溉小麦、玉米、棉花和高粱，均比不灌的增产 30 %以上；在春季河灌和汛期集中降雨淋洗的条件下，作物根层土壤不积盐；实行咸淡水轮灌，增辟水源，改善水质，可获作物增产。
