| 摘 要： | 从液体的压强公式出发,通过曲面积分,分2种情况,即静止液体密度均匀、物体密度分布任意时的情况和静止液体密度不均匀时的情况,求出浮力的作用点位置.同时也给出了一个通过空间曲面积分化简空间力系的实例.

| Abstract: | Proceeding from the pressure formula and with curved surface integral,it seeks the position of the action point of buoyancy in two different cases,i.e.,when the density of the static liquid is regular,the density of the substance is irregular;and while the density of the static liquid is not even.In the meantime,it provides a concrete example of simplifying solid force series with solid curved surface integral. |
