But the fat content of the body may be of equal importance, because it determines your buoyancy and the amount of energy you must expend to simply stay on the surface of the water.
但是身体的脂肪含量也同样重要，因为它决定了你的浮力和让你停留在水面上必须花费的能量。
To obtain optimum adhesion, it is crucial that the surface energy of the substrate is equal or higher than the surface energy of the material to be applied to the polymer.
为了获得最佳的附着力，重要的是，表面能的基材等于或高于表面能量的物质，适用于聚合物。
The acceleration of gravity is inversely proportional to the contact angle, and proportional to the surface energy when magnetic field intensity are equal.
磁场强度相等时，重力加速度与接触角呈反比关系，与表面能呈正比关系。
