It is necessary to predict hydraulic fracture height for providing pumping pressure increment and fracturing pressure reference value. 为了给压裂施工提供合理的泵压增量及地层破裂压力参考值,需要预测压裂裂缝的高度。
The simulation platform is used as the blood pressure reference standard in the measurement method research and to predict the continuous blood pressure. 将血压模拟平台作为连续血压测量方法研究中的血压参考标准,利用血压模拟平台对连续血压进行了预测。
Study on the Application Effect of the Zonal Pressure Reference(PR) 分层段压力资料应用效果研究
Two chambers of a capacitance diaphragm vacuum gauge are joined to the detected container and pressure reference container, respectively. 将薄膜电容真空计的测量室接于被测密闭容器,静态真空室接于一个比较容器,即组成一台压差式漏率测试仪。
The results show that the variation of both wall porosity and model size has marked effect on the static pressure at reference points of the plenum chamber and the variation of wall porosity alone has considerable effect on the surface pressure distribution of the airfoil. 结果表明,开闭比和模型尺寸对驻室静压有明显影响,开闭比对翼型表面压力分布有很大影响。
