例如，通径DN20的型号70A-T用于较小的室内和住宅环境，在10 psi (70 bar)压降下，水流流量为38公升/分钟。

The released species may facilitate and accelerate their detachment and diminish the initial elastic range of bone cement. This may create loosening or shrinking effect on the inserted stem. A conclusion for both behaviors suggest that a variation of relative and dynamic interface in use.

在骨泥与钛金属之长时间微幅运动作用下，骨泥材料受到压力、微幅运动及摩擦热的影响，其表面出现残屑堆积、热软化压平等现象，使得骨泥与钛金属界面产生滑移，进而产生残屑及粗糙度的改变。

When left when the test-drive after repair in shop main engine is adding this ship to 540r/min, supercharger occurrence asthma brace up phenomenon, rotate speed lifts slightly again, noise shakes very big, smoke evacuation temperature is normal, hair of on the high side of temperature of air inlet duct is very hot, as good as of smoke evacuation smoke constant, supercharger rotor rotate speed and the rotate speed of right leader supercharger that work normally comparative. 2 breakdown analyse this model diesel engine supercharger breathes heavily brace up the reason has the following sides. Bearing of 1 supercharger rotor damages, bring about on the low side of supercharger rotor rotate speed or wave motion, make inadequacy of compressor part air feed and diesel engine and its demand do not match, bring about air current not to stabilize generation to breathe heavily brace up. 2 diesel engine offers oil, match gas to time forbid, match gas, draw well time and disorder, bring about supercharger to breathe heavily brace up. 3 supercharger nozzle jams, cause smoke evacuation not free, circumfluence of exhaust stroke waste gas, enter jackknife of new energy of life with the below one stroke that take energy of life, produce air current to hit generation to breathe heavily brace up. Canal of 4 smoke evacuation jams, smoke evacuation not free, bring about waste gas circumfluence, hit generation of new energy of life to breathe heavily brace up. 5 jams into gas mouth, enter gas inadequacy, generation breathes heavily brace up. 3 trouble removal are based on above analysis, adopt the following measure to remove trouble.

该舰在厂修后试车时左主机在加至540r/min时，增压器出现喘振现象，转速再略升高，声响震动很大，排烟温度正常，进气管温度偏高发烫，排烟烟色无异常，增压器转子转速和正常工作的右主机增压器转速相当。2故障分析该型柴油机增压器喘振的原因有以下几个方面。1增压器转子轴承损坏，导致增压器转子转速偏低或波动，使得压气机部分供气不足和柴油机及其需求不匹配，导致气流不稳定产生喘振。2柴油机供油、配气定时不准，配气、发火定时紊乱，导致增压器喘振。3增压器喷嘴堵塞，导致排烟不畅，排气冲程废气回流，和下一进气冲程进新气重叠，发生气流冲撞产生喘振。4排烟管堵塞，排烟不畅，导致废气回流，冲撞新气产生喘振。5进气口堵塞，进气不足，产生喘振。3故障排除基于以上分析，采取以下办法排除故障。
