垂直循环[周期]
Variable pitch vertical axis turbines have been proposed, which can markedly increase the power extraction efficiency at low tip speed through controlling the rotor blades pitch at all points of their rotation cycle.
目前已经提出了一种变螺距垂直轴水轮机,它可以通过控制转子在一个旋转周期上所有点的叶片间距来显著提高能量的提取效率。
The vertical test testability design requests ensure the consistency and compatibility for test and diagnosis during the whole life cycle of weapon equipments. The study is important to improve the testability level and realize integral test for the weapon equipments.
纵向测试性设计要求保证了武器装备全寿命周期测试诊断的一致性和兼容性,该研究对提高武器装备的测试性水平和实现武器装备一体化测试,具有重要意义。
