二次能源可分为过程性能源和含能体能源。电能就是应用最广的过程性能源,柴油、汽油则是应用最广的含能体能源。目前过程性能源尚不能大量地直接贮存,因此汽车、轮船、飞机等机动性强的现代交通运输工具就无法直接使用从发电厂输出来的电能,只能使用像柴油、汽油这一类含能体能 Secondary energy can be divided into process energy and energy body energy. Electric energy is the most widely used process energy, diesel and gasoline are the most widely used energetic energy sources. At present, the process energy can not be stored in large quantities directly. Therefore, modern mobility vehicles such as automobiles, ships and aircraft can not directly use the electric energy output from the power plants and can only use such energy sources as diesel and gasoline Physical fitness
