New theory in the front of theoretical basis research of molecular thermodynamics 4: on molecular structure of organic compound and theoretical equation of critical pressure;

Prediction of the critical pressures of alkanes using a quantitative structure property relationship;

The critical pressure of two spans beams with one end fixed and the other hinge joined;

The curvature formula of tiny curved rod,together with the vector method of area,is applied to inference for Euler formula about critical load of slender compressive rod which one end is fixed and another is free.

And then,the equations are applied to inference for Euler formula about critical load of slender compressive rod with common constraints.

In elastic mechanics, it is common practice to calculate critical loads in buckle of thin plates by means of double triangle series.

Measurements of coefficient of convective heat transfer for endothermic hydrocarbon fuel up to supercritical pressures.;

Analysis and countermeasures of steam-excited vibration of supercritical pressure steam turbine;

In order to explore the underground heavy crude over 2000 meters in depth,a project of steam injection for supercritical pressure steam generator was designed and compared with the project of hot water injection by raising pressure of the former set hot water boiler.

Various temperatures and pressure differences through simulated test of determination HDPE bottle's deform during two sterilization processes were tested and the critical pressure differences between the inside of a HDPE bottle and its aluminum foil seal were gained.

The paper establishes dualitic regression equation among HDPE bottle's deform degree, various temperatures and pressure differences through simulated test of determinating HDPE bottle's deform degree during two sterilization processes;and gains the critical pressure differences between the inside of a HDPE bottle and its aluminium foil seal.
