查询词典 the first meridian

We performed a simulative test, which confirms that wavelet analysis can separate annual wobble and Chandler wobble. Our results show that this method can be used in astronomical geodynamies effectively. This paper is divided into two parts. The first is about statistic characteristic of polar motion. Polar motion includes secular motion, long period fluctuations, Chandler wobble, annual wobble and high frequency wobble. The secular motion is 3.4mas/year and towards 760W meridian. Long period fluctuations have difference periods in x-axis and y-axis. They are 31.7-year and 24-year in x-axis and 28.5-year and 22.9-year in y-axis. These 2~? decades fluctuations have an amplitude of about 30 mas , and are very nearly linearly polarized, with the observed motion of pole being almost entirely along a line between 360E and 1440W. There is a 55.4-year wobble whose amplitude is 9 mas. The amplitude of the interannual fluctuations is about 4? mas. The amplitude of long period fluctuations decreased after 1970. The annual wobble is a steady wobble. It retrograde wobble is only 1/20 of prograde wobble in amplitude.

本文的工作主要分为两部分：第一部分是通过分析POLE97序列，我们对极移的统计特性有了一个较全面的认识，极移主要包括趋势项、长周期项、Chandler项、周年项和高频项：趋势项的方向是西经76°，速度为每年3.4mas；长周期项中Markowitz 项在X、Y两个方向有不同的周期，它们分别是：X方向的两个周期是31.7年和24 年，Y方向的两个周期为28.5年和22.9年它们叠加在一起是一个线偏振运动，最大振幅约为30mas，偏振方向在西经144°和东经36°之间；极移的长周期波动中还存在一个 55.4年周期的圆周运动，振幅约为9mas；十年尺度变化的振幅在4～6mas之间，在Y 方向十年尺度的成份比较多，它们的周期在X方向和Y方向不是对应的；从七十年代年开始长周期变化的振幅明显降低；周年项是一个振幅稳定的摆动，在X、Y两个方向的振幅略有差别，逆向运动振幅大约为顺向运动振幅的1/20；Chandler摆动的振幅自1900年以来经历了几次较大的变化，其中包括1915年和1955年两次极大值，振幅分别达到0&。25和0&。28，以及1925～1940期间小于0.09的过程，Chandler项在X、Y 两个方向的振幅几乎完全相等，其逆向运动振幅不到顺向运动振幅的1/50。

He was also the first one that could clear the chest of living chest prime meridian, the promotion of women's hormone secretion and to protect their antioxidant scientists.

同时他也是第一个指出活胸素能疏通胸部经络、促进女性荷尔蒙分泌并保护它们抗氧化的科学家。

On May 14 2009 the world's first fully immersive 360 degree 3D nightclub was exhibited in the world famous 02 Dome in Greenwich (and thus aptly on 0 degrees longitude, the prime meridian of the world).

随着技术的稳定，2009年5月14日世界上第一个完全逼真的360度全景三维夜总会在世界著名格林尼治O2 Dome酒吧被展出（恰巧的是这里正是在0度经度，世界本初子午线）。

The brass marker in Saint-Sulpice was a memorial to the world's first prime meridian, and although Greenwich had stripped Paris of the honor in 1888, the original Rose Line was still visible today.

为了纪念那根铜条的制作者，本初子午线最初被这样确定。虽然，格林威治于1888年从巴黎手中夺走了这项殊荣，但当初的玫瑰线依然可见。

First,the paper summarized and analyzed the definition of the earth prime meridian in different periods,clarified the ambiguous recognition that the earth prime meridian was the meridian passing Greenwich astronomical observatory and gave the rigorous definition about the Earth prime meridian presently.

首先对地球首子午线在不同时期的定义进行了分析和总结，进一步明确了当前对地球首子午线的严格定义，澄清了地球首子午线即过格林尼治天文台的子午线这一模糊认识。

The Prime Meridian, which runs through Greenwich in south-east London, became the basis for the world's time keeping in 1884 after the first Astronomer Royal, John Flamstead, calculated that the Earth rotated on its axis once every 24 hours.

1884年，首位皇家天文学家约翰法兰姆斯坦算出地球每隔24小时绕轴自转1次，使得通过伦敦东南格林威治的本初子午线成为全球计时基准。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
