摘　　要：根据力学和热学的基本理论,分析和研究了球形液面内外的压强的形成机制,推出了球形液面内外的压强差的计算公式,利用凹凸球面附加压强公式分析计算了典型实际问题,对同类问题的分析与研究有一定的借鉴作用和参考价值.According to the basic mechanics and thermal theory, an analysis has been made on the spherical surface of the formation mechanism of the pressure inside and outside the spherical surface.A formula is achieved on the pressure difference inside and outside the spherical surface,with which some typical practical problems are solved according to the additional pressure of the concave and convex sphere.The result is of referential value to similar researches.
