If the direct pressure method cannot control bleeding , apply pressure over the arterial pressure points to facilitate blood coagulation . press for 5 to 10 minutes and never exceed 15 minutes 如直接压法仍未能止血,则可用动脉压点,施压协助止血,施压时间为五至十分钟,切勿超过十五分钟。
Exert pressure but avoid bandaging it too tightly by which may impair blood circulation to the end of the limb . if there is any foreign body or broken bone protruding from the wound , pressure may be exerted on the edge of the wound 如伤口有异物或断骨凸出,则可在伤口边缘施压。如直接压法仍未能止血,则可用动脉压点,施压协助止血,施压时间为五至十分钟,切勿超过十五分钟。
At the same time , its precision is obvious well than experiment one . square root of the average of the square summation of the difference between all estimated node water pressure h * and all real node water pressure h0 is 2 . 04m in xi ' ning network 计算表明,模糊聚类选择的测压点具有较好的代表性,估计的40个节点水压值与实测值误差的方均根为2 . 04m ,估计精度较高,能满足管网模拟的要求。
Then the most representative node in each group is selected as the locality for setting pressure measure apparatus . the pressure measure points in xi ' ning are optimized and selected by this way . there are 32 measure points which will be setted in the network ( 16 setted ) 本文利用模糊聚类方法,对影响系数加以分析将具有相同水压变化规律的节点划归为一组,最后在每组中选择最具代表性的节点作为测压点,从而优化选择了西宁市给水管网测压点。
The experimental results show that the critical transition point of chaos state by complexity analysis corresponds well with that proposed by chaos analysis , but complexity analysis is easier to be calculated . complexity theory not only provides a new method to analyze non - linear pressure fluctuation , but also have been proposed to be wide application foreground used in the future 涨落复杂性和最大lyapunov指数在对床内运动进入混沌状态的敏感指示这一点上,两者是一致的,但涨落复杂性和最大lyapunov指数相比,不易受到取压点高低位置不同的影响,在工业运用上更具有优势。
