解中的高次量效應是對赫芝理論的一個改進；它的影響隨着外力或接觸椭圓面偏心率的增加而顯得更重要。因此這個解在某些實際應用上如滚珠軸承中滾珠与珠槽間的接觸問題，是较需要的。

The purpose of this dissertation is to study a principle or method to describe and analyze the complex problems with high gradients arising from practical engineering. The main contents cover:1. The Bezier function was introduced to approximate high gradient functions, and a suitable coupled function was derived. Some detail numerical results show that the Bezier-based function is dominant over other combination function such as polynominal and trigonometric series, when to describe a high gradient function.

针对工程中大量存在的高梯度问题进行函数逼近的研究，引入Bezier函数对高梯度问题进行函数逼近，构成以Bezier函数为主的复合逼近函数，数值考证表明：与常规多项式插值函数的逼近及"幂／三角"复合函数的逼近相比，基于Bezier函数的逼近函数对高梯度问题的描述具有明显优势。

Organic Light-emitting Devices have been considered as the dominant candidates for prospective electronic devices and will replace the liquid-crystal display technology gradually , because they have a series of attractile advantages such as high luminescence efficiency, full colour display, broad viewing angle, low operation voltage, short response time, low working temperature, etc.

有机发光器件（Organic Light-emitting Devices，OLEDs）具有高发光效率、全彩显示、广视角、低驱动电压、快速响应和低工作温度等一系列引人注目的先天优势，被认为将在很多领域逐渐取代液晶显示技术，成为下一代显示器的主导。同时，基于有机半导体的有机器件由于其广阔的应用前景而越来越多地受到人们的关注。
