Michell ˈmɪtʃəl 高COCA¹⁰¹⁶²³BNC³⁶⁸⁰⁰ 基本例句 n.米歇尔¹⁰⁰ The concept of a body so massive that not even light could escape from it was put forward by the English geologist John Michell in a1783 paper sent to the Royal Society. 甚至如此庞大质量的物体以致于甚至光不能从它那里的逃脱概念由英国地质学者约翰·米切尔于1783年在寄往英国皇家学会的论文中提出来。 chinaufo.com Although he thought it unlikely, Michell considered the possibility that many such objects that cannot be seen might be present in the cosmos. 虽然他认为它不太可能,但是米切尔认为许多如此的物体可能性也许在宇宙中不会出现。 chinaufo.com In Michell's theory, the escape velocity equals the speed of light, but it would still, for example, be theoretically possible to hoist an object out of a black hole using a rope. 在米切尔理论里,逃逸速度等于光速,只是它静止,例如理论上可能使用一条绳索从黑洞里提取一个物体。 chinaufo.com It has been argued that ability measurement is the single largest contribution psychology has made to society Michell,1999. 有争议说能力测量是心理学唯一对社会作出的巨大贡献 Michell1999。 yeeyan One of the simplest and most efficient types of water turbine for small-scale use is the Australian Michell or' Banki' turbine. 水轮机的一个最简单,最有效的各类小规模使用的是澳大利亚米歇尔或'本吉'涡轮机。 tech-domain The Michell turbine is very amenable to power control by means of narrowing the feed- nozzle width and for fine control by means of a throttle plate in the throat of the feed- nozzle. 涡轮的米歇尔是非常经得起权力控制缩小饲料喷嘴宽度和良好的控制手段通过在饲料喷嘴喉部油门板的手段。 tech-domain This means that there is a conceptual inaccuracy in the nonrelativistic concept of a black hole as originally proposed by John Michell in 1783. 这意味着有一个黑洞概念上的错误如1783年被约翰·米切尔提议的那样。 chinaufo.com 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。 tech-domain Michell computed that a body500 times the radius of the Sun and of the same density would have at its surface an escape velocity equal to the speed of light, and therefore would be invisible. 米切尔计算一个500倍太阳半径而且具有相同密度的物体就会具有它的表面逃逸速度等于光速,而因此不可见。 chinaufo.com |
