So called reservoir is physical or mathematical; for a physical system, the mathematical model is a system of partial differential equations with related initial and boundary value conditions, it can describe important physical process occurring in the system, for example, the process occurring in reservoir, which mainly concludes flow of fluids and transportation of mass, gravity、 viscosity、compressibility have effect to it; differential equations describing this process are obtained by combining Darcy law of every phase and its mass equilibrium in differential form.

这种模型是物理的或数学的；一个物理系统的数学模型，是偏微分方程组和适当的一组初、边值条件的总体，它能够描述在系统中发生的重要的物理过程，比如在油藏中发生的过程，主要是流体的流动和质量的转移，重力、粘滞力、压缩性等在流体流动过程中都是起作用的；描述这个过程的微分方程是由将各相达西定律和各该相的微分形式的物质守恒相结合而得到的。

根据受试者的最小红斑量，在三组人群的另一侧上臂内侧分别给予1.5倍MED、2倍MED、2.5倍MED剂量的紫外线照射，一周后肉眼观察判断红斑消退情况、黑素强度、黑素均匀度及表面光滑程度等情况，在照射前及照射后的第1、2、3、4、5周分别用CM2500分光测色仪及Mexameter18红斑黑素测量仪采集数据L、a、b、M、E值。

However, the relationship between skin temperature regulation over the area with trigger points and referred pain is still unknown. Therefore, to implement the use of infrared thermogram as a plausible tool for the clinical assessment of referred pain in MPS and treatment assessment, current study will propose a human experiment based on the thermo-changes in skin temperature for patient with MPS.
