The generating reason,response characteristic and distributing rule of remaining oil was deeply studied aiming at water-flooded continental reservoir with characteristic of intense heterogeneity,high water-cut,low recovery efficiency,complex distributing rule of mobile remaining oil,intergrowth of major and untabulated formation . At the same time,a systemic method of evaluation and predicating remaining oil and pressure was put forward basing on the theory of development geology,seepage flow mechanics,fluid mechanics which resolved the hard technologic problem of predicting remaining oil and pressure.

本文针对陆相注水开发油藏具有非均质性强、含水率高、原油采收率低、可采剩余油分布复杂、主力产层和表外产层同时存在等特点，深入研究了剩余油的形成机理、响应特征和分布规律，应用开发地质学、渗流力学、流体力学和地质统计学理论，将静态地质数据和动态开发数据相结合，综合现有的与剩余油及压力分布有关的所有资料，提出了一套系统的评价和预测剩余油及压力的方法，较好地解决了目前剩余油与压力评价和预测中的技术难题。

In this paper, finite element method is used in the analysis of cross section temperature field of I-shaped steel beam under fire in different position. It can gain the temperature contours and its rules.

本文采用有限元方法，对工字形钢梁在不同位置火焰下横截面温度场的分布情况进行了分析，得到温度场分布云图及其分布规律。

From FEM, the contact stress obeys the semi-ellipse distribution and the Mises stress and shear stress are also consistent with contact mechanics theory, but there exists offset or deflection in the symmetric lines of stress distribution, which originates from tooth bending deformation.

由有限元方法得到的渐开线轮齿的接触应力符合Hertz理论中的半椭圆分布规律，Mises应力和剪应力分布也符合接触力学理论，但应力分布的对称中心存在偏离或者偏斜现象，分析认为，是由于轮齿弯曲变形造成的。

The hoop tension force is axisymmetrical about the tension direction and increase from the top position to both sides. The distribution of hoop tension force is even with small friction coefficient, but will increase rapidly from top to side positions, which subsequently result in necking and fracture near the edge of gauge section.

结果表明：采用正压力线性变化假设所得的切向力分布规律与拉伸实验结果吻合较好；切向力关于拉伸方向呈轴对称分布，从正上方到两侧逐渐增大；当摩擦系数较小时，切向力分布较均匀，但当摩擦系数较大时，切向力从正上方到两侧迅速增大，试样的颈缩和断裂发生在标距段内靠近标距边缘的位置。
