繞轉周期
英文
rotation period-
Is 29. 5 days. interestingly, the rotational period of the moon relative to the sun is exactly the same as the synodic period
盈虧月。月球的自轉周期剛好和它的繞地公轉周期相等，這種情形稱為Overlap between the second hand and minute hand, or the 11th overlap between the minute hand and hour hand, which is 12 hours later. actually it is easy to see this must be one of the answers. but it is a bit surprising that they simply do not overlap at other times
天文學家斯特格及奧爾特在1950年提出在太陽以外五萬個天文單位的地方，有一個包圍著太陽系，以太陽為中心旋轉的雲團，我們所見的長周期彗星，就是從這個彗星雲又稱為奧爾特雲而來，估計那裡有1 ， 000億顆彗星，其總質量比地球質量小，繞太陽公轉一周需時數百萬年。They found two events showing the shortening of pulsating cycle and decaying of radiations intensity. the signatures matched theories of what scientists would predict to see. when matter is falling so close to the event horizon, it will be circling the black hole with increasing speed and its light will rapidly dim as it is stretched by gravity to ever - longer wavelengths
研究人員分析了極大量來自緻密天體天鵝座xr - 1的紫外線輻射，發現其中兩組數據顯示，輻射脈沖的周期隨時間縮短，而其強度則隨時間衰減至消失，這現象與一些物質在接近黑洞視界時繞著黑洞急促旋轉，放出的輻射因為重力紅移而衰減的情況相符。And the lower level, rule execution language, is used by the rule engine. the task of this paper is to discuss the principles of business rule management concentrated on the life cycle of business rules, and based on this, the design and rezilization of our business rule management system is presented
本文首先分析總結了業務規則技術的基本原理，圍繞業務規則的生命周期論述了業務規則方法的思想，提出了ccbrms的整體框架；進而論述了一個三層業務規則語言模型，描述了各層規則語言的功能、語法和語義，以及語言之間的轉換關系。In fact, pluto orbits in a 3 : 2 orbital resonance with neptune meaning that for every three complete orbits that neptune makes around the sun, pluto completes two
事實上，冥王星與海王星公轉周期有3 : 2的共振關系，即海王星每環繞太陽三周，冥王星便會環繞太陽兩周。分享友人
