结果显示江汉盆地热流419～609 mW/m2，平均523 mW/m2，盆地总体表现为较低的大地热流，反映了中新生代以来构造活动逐渐减弱，盆地不断冷却的结果；从盆地内热流分布看，热流分布南高北低，反映了江汉盆地构造活动的不均一性。

The significant improvement might be caused by the Cu substrate which has higher thermal conductivity than conventional Sapphire substrate. However, Cu substrate is a ductile metal plate and easy to deform during the processing. The deformation of the Cu substrate will destroy the LEDs that were bonded on the Cu substrate. Finally, LEDs will be fabricated on the patterned Cu/Si substrate to make high-power LEDs and solve the deformation problem in processing.

主要是因为利用铜基材去取代蓝宝石基板使其具有较高的散热性，可以使元件在较高的饱和电流下驱动以达到高功率的目标，然而，铜金属是延展性佳的材料，因此，在整个元件的制做过程中，易造成发光二极体元件毁坏，利用本实验的方法可以提升制造高功率发光二极体之良率。

预处理实验结果表明：采用有机除油和化学除油即可清除聚氨酯泡沫表面油污；反复充分挤压泡沫，控制聚氨酯泡沫均匀减重2.0～3.0mg·cm~(-3)可获得良好的粗化效果；用硝酸银型代替氯化钯做活化剂，并施以适当的工艺同样可取得良好的活化效果。

The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.

二项式产能方程只能描述高速非达西渗流，对于低渗压裂气井，地层的低渗透性和裂缝的高导流能力使得其渗流规律已经和压裂前大不一样，二项式产能方程已无法描述气井的生产状况，必须建立新的方程。
