开口

I speak reasonably good German (although it's not perfect, and people can generally tell I'm English by the time I've uttered about 3 words), which is more than adequate to cope with the sort of discussions you have with hotel staff, and I find it quite patronising if people speak back to me in English.

我自己的德语说的不错（当然也不是特别好，因为当地人能在我开口说三个字以后就知道我是英国人），至少和宾馆人员交涉是绝对没问题的，另外，我个人觉得如果我说德语而别人回我英语，好像是施舍似的，令人不舒服。

When the flow through the balance of the piston damping the flow of holes increases, the balance of the piston, the next increase in pressure on both sides of a balanced increase in the distance the piston increases, and vice versa reduced; and also because the spring stiffness is very small, so that shift the balance of the piston pressure required very few changes, so the flow through the Poppet head is not much change, so the first opening Poppet very few changes, to mention the pressure of moving the first opening can be said to remain unchanged, that is, when the pilot valve spring after a set, Poppet Head was opened, the balance piston chamber pressure remained basically unchanged.

当流经平衡活塞上阻尼孔的流量增加时，平衡活塞上、下两侧的压差增加，平衡活塞上升距离增加，反之则减小；又因为弹簧的刚度很小，使平衡活塞上移所需压差变化很小，所以通过提动头的流量变化也不大，因此提动头的开口变化很小，提动头开启的压力可以说是不变的，亦即当先导阀的弹簧一经设定后，提动头被打开时的平衡活塞上腔的压力基本保持不变。

As to the mate lag problems in loom beat up mechanism,comparing traditional four bar linkages with quick return four bar linkages beat up mechanism,the latter can solve the lag problems effectively.A CAD method of designing the quickreturn four bar linkages beat up mechanism is pointed out,and the design mathematics model and the kinematic analysis model are also presented.
