| 摘 要： | 为研究轴对称凸域的包含测度，以等腰梯形域为例，采用直线的广义法式方程，给出了等腰梯形域的广义支持函数与限弦函数的解析式。采用限弦函数法，得到了等腰梯形域的包含测度，并取消了“等腰梯形的高不超过梯形的最短底边长”这一限制条件。 |

| Abstract: | In order to analyze the containment measures of axisymmetric convex domains, this paper takes the isosceles trapezoid as an example. The generalized support function and restricted chord function of an isosceles trapezoid domain are obtained by employing generalized French equation of a straight line. Based on these, the containment measure of an isosceles trapezoid domain is derived without the constraint that the height of an isosceles trapezoid does not exceed its shortest base edge is omitted. |
| Keywords: | containment measure generalized support function restricted chord function Buffon problem kinematic measure |
