| 7. | But the hinge for the oar broke , so i had to row canoe - style ( which is less effective than rowing with a hinge , and then you have to use one oar ) 然而划桨的安架坏了,因此我必须用划独木舟的方式来划(这是比安桨式较没效率的,而且你必需使用一个桨划行) 。 |
| 8. | A pcc based stepping motor driven dual control governor for kaplan turbine is presented in this paper . the governor adds the function of adaptive control of blades and radius basis function cam network based on the current pcc based stepping motor driven single control governor 该调速器在当前pcc步进式水轮机单调整调速器的基础上引入了桨叶自适应控制和基于rbf网络的协联装置,可定期对转桨式水轮机协联关系进行自校正,保证水轮机始终运行在较高效率区。 |
| 9. | The axial flow type turbines are available for hydrauric power resources of medium and low heads . ganfa manufactures both the propeller type fixed blade type and the kaplan type adjustable blade type turbines . the propeller type turbines are suitable for hydropower stations with small or medium capacities and heads , and relatively stable loads . the kaplan turbines are suitable for hydropower stations with medium or large capacities and heads , and relatively unstable loads 轴流式水轮机适应于开发中低水头水力资源。我公司生产的轴流式水轮机按转轮结构分为定桨zd转桨zz两种,定桨式一般适用于中小容量及水头负荷变化较小的的水电站转桨式多用于大中型电站及水头负荷变化较大的水电站。 |
