pressure rise
1.A STUDY ON THE PRESSURE AND RATE OF PRESSURE RISE IN ENERGETIC MATERIAL DUSTS
3.With the relationinvestigation of aerodynamic load and combustion noise through the analysis ofcylinder pressure, rate of pressure rise, heat release rate and combustion noiseobtained by design a time window, it is found that the rate of pressure rise is themain dynamic load factor that affects the combustion noise.
5.For a specific brake mean effective pressure(BMEP),the maximum cylinder gas pressure,the maximum rate of pressure rise and the maximum rate of heat release increase with the increase of DMC addition at the middle and high loads while they remains less variation with DMC addition at the small load.
6.Results Compared with sham-operated group, after AMI, systolic, diastolic , and mean arterial blood pressures (SBP, DBP, MAP), left ventricular systolic pressure (LVSP) and the maximum change rate of left ventricular pressure rise and fall (±dp/dt) were significantly decreased (P<0.05~0.01), while left ventricular end diastolic pressure (LVEDP) was significantly increased (P<0.05) in MI48h group;
10.When the temperature of the medium is constant, the analysis of data presents that the diffusion coefficient of moisture increases with the reduction of absolute pressure and the rise of changing rate of pressure, among which the effect of the latter makes a big difference compared with that of the former.
