Unexpected proteome plasticity in response to persistent temperature rise
temperature protein yeast molecular biology climate change
2021/8/3
Common yeast are able to adapt and thrive in response to a long-term rise in temperature by changing the shape, location and function of some of their proteins. The surprising findings demonstrate the...
工作油温升对液粘传动调速起动的影响（Effect of Working Oil Temperature Rise on Hydro-viscous Drive Speed Regulating Start）
液粘传动 调速起动 温升 修正瞬态雷诺方程
2010/12/29
采用有限元法联立求解修正瞬态雷诺方程、热能量方程及润滑油粘温方程，对调速起动过程进行了数值模拟研究,讨论了起动过程中工作油温升对液粘传动调速起动的影响。结果表明，流入摩擦片工作油温度为30℃时，流经摩擦片后温度约升高20℃，它所引起的油膜承载力下降9%；而流入摩擦片工作油温度由30℃升至50℃时，即使不考虑流经摩擦片的温升，油膜承载力也将下降32%。这样易引起油膜承载力低于比例溢流阀死区对应压力，...
