摘　　要：我们在研究胸压影响心功能机制,特别是对奇脉机制研究所做的生物力学实验的基础上认识到,在忽略固体材料可压缩性的条件下,帕斯卡定律可拓展应用到其他物体。我们将这一拓展后的定律命名为广义帕斯卡定律。广义帕斯卡定律指的是,流体静压强可无损地向处于其内的无封闭空腔的固体和软物质,包括生物组织中传递。帕斯卡定律是广义帕斯卡定律的特殊情况。广义帕斯卡定律可使我们对流体力学基本规律有更深刻的理解。本文通过数学证明及临床实验各个方面证明广义帕斯卡定律的正确性。广义帕斯卡定律应在研究流体静力学时得到应有的重视。We extended the application range of the Pascal’s law from incompressible fluid to soft biological tissue when investigated the mechanical principle of heart-lung interaction issues such as pulsus paradoxus. Furthermore, we originally found the Pascal’s law could be extended even to incompressible solid inside the fluid. This extended Pascal’s law may then have a general meaning. We temporarily name it the General Pascal’s law. General Pascal’s law states that pressure exerted anywhere in a confined incompressible fluid is transmitted undiminished throughout not only the fluid but also the incompressible solid inside the fluid. Pascal’s law is only a special situation of General Pascal’s law. This newly proposed General Pascal’s law may be a possible basic hydrostatic law, disclosing the rule of the force transmission from liquid to solid, and may lead to a deeper understanding of the mechanical nature of the world and may lead us to rethink about some phenomena that we did not really know. In this paper the mathematical approach and experimental work of ours and other researchers’ were included to support this new law.
