1·The practical problem of the allowable pressure of the proposed bearing layer is discussed.

并探讨了有关建议中提出的桩端持力层容许承载力参考数值的实用问题。

2·The available method for determining basic size of cam mechanism according to its allowable pressure angle is lack of appropriateness.

现有按许用压力角确定凸轮机构基本尺寸的方法欠妥。

3·Thus the valve control valve flow capacity than the average large and no leakage in the range of allowable pressure shut-off valve can be used.

因而阀流通能力比一般调节阀大且无泄漏，在许用压差范围内可作切断阀用。

4·The pump is rated pressure pump work for the highest allowable pressure, but their work is determined by external pressure load, pump life are directly related to their work pressure.

泵的额定压力是指泵连续工作时的最高许用压力，而其工作压力则决定于外部负载，泵的寿命与其工作压力直接相关。

5·The flange maximum allowable working pressure should not be smaller than the computed pressure of this flange in operation.

法兰最大允许工作压力应不小于该法兰在使用条件下的计算压力。

6·The obtained lowest allowable flowing pressure value can be used as an important basis for allocation and design of an oil field.

得到的最低允许流动压力数值可作为油田配产和油田规划设计的重要依据。

7·Butterfly spring valves are important safety attachments of boiler pressure vessels, they are used to prevent system pressure from exceeding allowable limit value.

蝶形弹簧安全阀是锅炉压力容器的重要安全附件，用于防止系统压力超过允许的极限值。

8·With the known formation pressure and saturation pressure, this formula helps to calculate the lowest allowable flowing pressure of a well or an oil field.

有了这个公式，只要知道地层压力和饱和压力，便可计算出油井或油田的最低允许流动压力。

9·By using the surge pressure calculating method, in this paper the formulas have been derived which are used to calculate the maximum allowable velocity in pulling and running pipe in borehole.

本文根据波动压力计算方法推导出了最大许用起钻速度和下钻速度的计算公式。

10·The dynamic working pressure in this catalog refers to the allowable maximum pressure in condition of continuously working.

资料中有关胶管的动态工作压力是指胶管连续工作时允许的最高压力。
