In this paper, a distributed parameter model of room air-conditioner adiabatic capillary was developed, on the basis of mass-energyconservation and momentum conservation.
本文根据质量守衡、能量守衡、动量守衡原理，建立了房间空调器绝热毛细管的分布参数模型。

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。
