there is in fact so much speed in the actuator that hydraulic restrictors are used to slow it down and prevent damage 事實(shí)上液壓節(jié)氣門減慢了驅(qū)動(dòng)器的速度以防止損壞。
hence the research on the problem seems meaningful theoretically and realistically . the thesis will begin with studying ontology of press supervision and end with defining the social rules and restrictors on it 本文行文思路發(fā)于對新聞輿論監(jiān)督本體論的考察而終于社會(huì)對其運(yùn)行規(guī)則的框定,力圖在理論和實(shí)踐兩個(gè)層面闡釋它的科學(xué)性。
in this paper, the pressure field and static characteristic of bearings are simulated by fluent . the pressure contours of restrictors and shaft are acquired as well as the load capacity and static stiffness curves versus eccentricity ratio 本文首次應(yīng)用它對軸承的壓力場和靜態(tài)特性進(jìn)行了仿真分析,得出了氣體流經(jīng)小孔、多孔柱塞和全多孔質(zhì)的壓力變化曲線以及軸上壓力沿軸向和圓周方向上的變化趨勢,并給出了軸承的承載能力和靜態(tài)剛度曲線。
