The actual concept of an object so massive that light could not escape was suggested in1783 by the geologist John Michell. 这一说法的确切成型时间为1783年,是由地质学家米歇尔提出的。
Michell's always getting lost because of her terrible sense of direction. 由于方向感极差,米歇尔总是迷路。
Whilst being fairly compact in size, the construction of a Michell turbine requires substantial structures since a small runner can still produce output power comparable to a Mack truck. 虽然目前的规模相当紧凑,一个米歇尔涡轮建设需要大量的结构,因为一个小运动员仍然可以产生输出功率相当于一个麦克卡车。
Using the Michell solution and the crack solution, the integral equation of a radial crack in a hollow cylinder reinforced on its outer boundary is derived. 本文结合使用Michell环形域级数解及单裂纹解,导出了外边界被加劲的空心圆柱的径向裂纹积分方程,进而分析了加劲薄膜对裂纹应力强度因子的影响。
