查询词典 lunar eclipse

During the New Moon (the 1st of a lunar month) and the Full Moon (the 15th of a lunar month) when the Earth, Moon, and Sun lie in a straight line, the solar and the lunar tides overlap and the sea-level pressure is lower than the mean at the Airport, because the tide-producing force induced by the Sun and Moon reaches maximum. On the other hand, during the First Quarter (the 7th day of a lunar month) and the Last Quarter (the 21st of a lunar month) the Sun-Earth's and the Moon-Earth's relative positions are perpendicular to each other with respect to Earth, the solar and the lunar tides interfere mutually, the Airport sea-level pressure is greater than the annual mean due to the tide-producing force reaching minimum.

松山机场在朔望月里，每逢阴历朔日或望日，受太阳与月球之引潮力(Tide-producing force)方向一致，太阳潮和太阴潮重叠影响，其全日和逐时平均海平面气压比年平均为低；而每逢上弦和下弦时，日地与月地的相对位置成直角，太阴潮和太阳潮相干扰，其全日和逐时平均海平面气压则比全年平均为高。

Lunar eclipse can be divided into partial eclipse, total eclipse and the penumbral eclipse of the three kinds.

月食可分为月偏食、月全食及半影月食三种。

In this paper, a series of lunar map projection formulas are deduced including azimuthal projections, cylindrical projections and conical projections. The lunar map projections software is compiled. By caculating lunar map projection distortions, their projection distortion rules are found. Base on the lunar exploration mission, the lunar map projection scheme is given in this paper. The azimuthal conformal projection or the circumcenter perspective azimuthal projection is usually used in small areas, especially in two poles. When the whole map of the moon is needed, the azimuthal conformal projection or the circumcenter perspective azimuthal projection is used within 10° in the poles, and the traverse tangent cylindrical conformal projection or the normal secant conical conformal projection can be used in else areas, furthermore, band-division is necessary to reduce the projection distortion.

本文推导了基于月球参考球的各种投影公式，主要包括方位投影、圆柱投影和圆锥投影；编制了月球地图投影计算软件；对多种月球的投影变形进行了详细的计算，总结分析了各种月球投影的变形规律；结合月球探测的需要，给出了月球投影方案的建议：对于局部的面积较小的投影区域，建议使用等角方位投影或外心透视方位投影；如果绘制月面全图，在两极10°范围内采用等角方位投影或外心透视方位投影，其余区域可以采用等角横切圆柱投影和等角正割圆锥投影，并且要进行分带处理。

Dhofar 1180 is a unique lunar meteorite that differs petrographically and geochemically from all other lunar meteorites and lunar samples.It comes from a region on the lunar surface that has not been sampled by any other known lunar rocks.

Dhofar 1180的矿物学、岩石学和微量元素地球化学特征与已知的月球陨石和月岩样品有明显的差异，它来自月球表面的一个新的未知地区。

Let's cite some events for illustration: in 29 BC of the Han Dynasty:"On syzygy solar eclipse occurred in the daytime and then an earthquake struck at night"; in 120 of the Eastern Han Dynasty:"On syzygy solar eclipse occurred in the daytime; soon afterwards earthquake hit 8 regions"; in1068 of the Song Dynasty:"Earthquake struck again and at night lunar eclipse occurred"( the History of the Song Dynasty ) and etc.

比如汉朝公元前29年——朔，日有食之。

Central eclipse 中心食 A central solar eclipse occurs when the Moon's shadow axis touches Earth; a central lunar eclipse occurs when the Earth's shadow axis touches the Moon.

当月球的影轴於日食过程中经过地球时，该次日食便为中心食；月食方面，当地球的影轴於月食过程中经过月球时，该次的食就称为中心食。

Singapore Science Center science teacher said that in general solar eclipse 15 days after the lunar eclipse will occur, but only "on the entire loss" of the moon will show the dark red, the Lantern Festival in 2009 only "on partial eclipse."

新加坡科学馆科学教员说，一般日蚀后第15天就会出现月蚀，但因为只有&月全蚀&的月亮会呈现暗红色，2009年元宵节只是&月偏蚀&。

He makes a record of 2,500 planets visible in central China and the first star Chart of the country. Regarding the formation of the Lunar eclipse, he makes the correct interpretation that the moon itself does not give light but reflects the light from the sun, that the dark part of the moon is the part that receives no light and that the full moon is seen when the moon and the sun are in the opposite positions; when the moon moves to the same direction with the sun towards the earth, the lunar eclipse is seen.

记录了中原地区能看到的2，500颗恒星，并且画出了中国第一张完备的星图，正确解释了月食成因：月亮本身不发光，受到太阳的照射才反射出光来；月亮的黑暗部分，就是没有照射到太阳光的部分；月亮的位置和太阳相对的时候，就是满月；月亮运行到跟太阳同一方向的时候，就是月食。

In this paper, the theories of lunar control network foundation and lunar map projection are studied. Three foundation methods of lunar control network and the progress in American lunar control network are summarized and analyzed.

月球大地测量是月球探测的主要任务之一，本文主要对月面大地控制网的建立理论以及月球投影的理论和方法进行研究。

In addition to the family reunion, visiting friends and other essential elements; Hong Kong's Spring Festival features include : Lunar New Year Fair : A few days before the Lunar New Year, held in various districts, including the annual Lunar New Year Fair in Victoria Park's most popular, selling peach, chrysanthemum, narcissi and other Lunar New Year flowers and other commodities.

除了合家团圆、拜访亲友等必不可少的内容；香港的春节特色项目还有：年宵花市：农历新年前数天在多区举行，其中一年一度的维多利亚公园年宵花市最热闹，出售桃花、菊花、水仙花等各种贺岁鲜花及其他商品。
