piston action
解釋
活塞效應-
Machining process for main piston of 100 mn double - action aluminium extrusion press
雙動鋁擠壓機主柱塞的機械加工工藝 -
Hard - chromed piston rod with micro - grooves, increasing the rigidity and reducing friction, keep better lubrication action
活塞桿微裂紋鍍硬鉻，增因硬度減少磨擦，保持油膜潤滑效果值。 -
Without this shock-absorber action the piston could bounce up and down, causing erratic carburetor action and poor engine performance.
沒有這個減振作用，活塞會上下竄動，引起化油器工作異常，導致發動性能變壞。 -
A open - close mathematic model is introduced into calculation of torsional vibration. results show : kurtosisness and high harmonic will increase when crankshaft have crack. 5. cylinder score is also diagnosed by torsional vibration in this paper, when cylinder score occurring, the friction of piston will decrease the action of air pressure
本文借鑒了裂紋轉子剛度的開閉模型，首次對含有變剛度單元的柴油機動力裝置進行了扭振計算，結果表明柴油機曲軸有裂紋后，扭振的角位移和附加振動力矩的高諧次分量會增加，峭度值增加。 -
First, the difference between the stm and utm is compared and analyzed. the results show that it can accurately simulate the unsteady flow process of piston wind and the pollutant distribution in tunnel after train left the tunnel, can analyze and calculate the good effect of inertial action of piston wind if using utm
文中首先分析和比較了傳統隧道通風設計所採用的恆定流理論與非恆定流理論的差別，表明運用非恆定流理論不僅更能準確模擬隧道內活塞風的非恆定流動過程，而且能模擬列車通過隧道過程中隧道內污染物濃度的分佈，同時還能考慮利用隧道內氣流（活塞風）慣性作用促進隧道通風，節約通風能耗。 -
Analysis on two - and three - dimensional thermal - field of the coupling model of piston assembly and cylinder, including steady analysis and transient thermal analysis with 2 - d and 3 - d model and the stress and the deformation under the action of thermal load
分析中包括了二維模型的穩態傳熱分析、瞬態傳熱分析和三維耦合模型的穩態傳熱分析、瞬態傳熱分析，以及附帶的熱應力和熱變形分析。 -
Then, two aspects of energy conservation in tunnel ventilation system are attained. one is the lessening of pollutant length needed to be removed ; the other is using the inertial action of piston wind to remove pollutant
然後，在滿足衛生標準的前提下，根據不同時刻隧道內污染物濃度分佈，得到在兩個方面會帶來隧道通風系統較大的節能，一是需要排除的污染段長度減少，另一方面是充分利用隧道內氣流的慣性作用排出污染物。
