| 6. | Adopt advanced technic of f4 whole cold - press to moulding and heat melt to process to make , let the lining no slot to link withal cheek by jowl connect with exterior metalpipes wall , in the state of allowwing to work keep to distort in - phase , thereby to enhance using - life of lining in the working status of opposite high temperature high vacuum , stop the ecumenic pad fluorin pipes using in condition of cold and heat alternate and minus tension to come into being the matter of padding fluorin floor shrivel to jam the flowway and plastic rip , its perfect choice use to transport medium of strong corrosive strong oxidation by modern chemical - industry corporation
采用氟塑料f4整体冷压成型及热熔加工等先进技术制造，使内衬层无缝搭接且与外层金属管壁紧密粘接，在允许工作状态下能够保持同步变形，从而提高了衬里层在相对高温高真空度的工况下的使用寿命，杜绝了一般衬氟管在冷热交替，及负压的条件下使用易产生衬塑层鼓瘪阻塞流道及塑料拉裂的问题，是现代化工企业在输送强腐蚀强氧化介质理想的选择。 |
| 7. | According to the comparison between simulation results and laboratory measurements , this paper reaches the conclusion that the negative pressure region in convex boundary ( including broken line gradient ) not only caused by boundary layer separation , but also especially caused by centrifugal force which is the result of convex boundary
根据数值计算与模型试验结果的比较，得出具有凸形曲面边界（包括折面底坡）负压区的存在不仅是边界层分离所致，边壁弯曲使过流产生的离心力也是产生负压的重要原因的结论。 |
| 8. | Among the pathophysiological mechanisms , the sudden shift from a positie to a negatie intrathoracic pressure plays an important role since it results on the one hand in an increased pressure gradient for systemic enous return and in cardiac preload and on the other hand in a decreased pressure gradient for left - entricular ejection and an increase in left - entricular afterload
在诸多病理生理学机制中，胸内正压向胸内负压的突然转换扮演了重要作用，一方面，是由于增加了体循环静脉回流的压力梯度和心脏前负荷，另一方面，降低了左室射血的压力梯度并增加了左室后负荷。 |
| 9. | Due to technology demand would carry out multi - place measure of wind pressure or negative pressure . because measured medium include high concentration coal powder and coal dust grain , often makes sample pulse pipe to stop up , and effect on correct measure of wind pressure , so to safety production causes serious menace
由于工艺上的需要，要进行多处的风压或负压的测量，因被测介质中含高浓度的煤粉或煤灰颗粒，常使取样脉冲管堵塞影响风压的正确测量，对安全生产造成严重威胁。 |
