The results show that the excess pressure has a very important effect on the critical nucleation radius and the thermodynamic barrier in the for mation of a critical nucleus.

Focusing on relevant concepts in Physics and Chemistry such as additional pressure under curved surface, this article discusses the errors made in"The Discussion about Deduction Method of Kelvin Equation", published on the Journal of Fujian Institute of Education, No.

Some problems, such as additional pressure, settlement of high-rise buildings, thermal compensation of risers, gas metering, safety measures in the design of indoor gas pipe in high-rise buildings are discussed.

This text studys the cause and process of the additional pressure of the liquid of parallelplate capacitor inside, releases the calculation formula of the additional pressure in its internal liquid, proves accuracy of formula‘ F=F 0/ε r ’,and announces to public the innate character of the additional pressure in internal liquid of parallelplate capacitor inside.

Polymer solution rolling action on the diesel oil bending interface is explored by the lab experiments and by the knowledge of the interfacial thermodynamics and the polymer thermodynamics,and the extra pressure change of diesel oil bending interface is analyzed.

This paper calculates the extra force caused by a driving automobile on pavement with a hollow spot, and analysis the main factor influencing to the extra force.
