It is dependent on the temperature differential between the inside and outside air, type and thickness of insulation, and the area of the conducting surfaces.
这个主要取决于内外空气的温度差、绝缘层的类型和厚度以及传导面的面积。

Based on the mathematical models of the air-in area and air-out area, the differential equations of the internal energy and mass of the gas in the cylinder were proposed.
为此在建立了摆盘发动机配气过程进排气面积数学模型的基础上，建立了缸内工质的内能和质量的微分方程。

The decentralization of sampled value and the uncertainty of sampled time bring forth the action fuzzy areaof sampled value current differential protection.
