学过物理学的人都知道,物理学上有一个帕斯卡原理。它告訴我們:“在封閉的容器內的流体,能够把它所受到的压强,按照原来的大小,向着各个部分传递。”譬如:拿二个粗細不同的容器,下面用一根管子把他們連起来,装上水,再用二个活塞把二个容器的口都塞住,就成了一个最簡单的水压机模型。如果小活塞面积是一平方厘米,大活塞的面积是一百平方厘米。那么,小活塞 Those who have studied physics know that there is a Pascal principle in physics. It tells us: “The fluid in a closed container can transfer the pressure it receives to its original size, according to its original size.” For example: Take two containers of different thicknesses, and use a tube to hold them down. Together, put the water, and then use the two pistons to plug the mouth of the two containers, it has become a simple model of the hydraulic press. If the small piston area is one square centimeter, the area of ​​the large piston is one hundred square centimeters. So, small piston
