conservation of mass and energy

基本解释

Design and testing of these physical systems rely on standard design practices that employ the laws of conservation of force, mass, and energy.
这些物理系统的测试依赖于对作用力、质量和能量守恒定律的标准设计实践。
The dynamic system model is coupled with geothermal heat exchanger model and heat pump unit model, which is based on the conservation of mass and energy.
采用确定性模型法建立了热泵机组的模型，然后通过能量和质量守衡方程式建立了系统动态耦合模型。
Based on the conservation of mass, energy and chemical compositions, a model of seam-cavity growth is established to describe the process of underground coal gasification.
通过质量守恒、能量守恒和化学组分平衡描述了煤炭地下气化过程，建立了煤炭地下气化中燃空区煤层扩展的数学模型，根据试验条件进行数值求解。
