You now have the ecliptic longitude of perigee of the sun for the mean summer solstice of your chosen year (and effectively for the entire year).(你現(xiàn)在有黃道經(jīng)度的近地點(diǎn)的陽(yáng)光平均夏季冬至，你選擇了一年(而有效地為整個(gè)一年)。)

In this paper, variations of AE-D's perigee altitudes, the corresponding atmospheric expansion and the density distributions are analyzed.(本文分析了AED極軌衛(wèi)星近地點(diǎn)的變化及其相應(yīng)的大氣膨脹和密度分布情況。)

If you managed to miss this perigee Full Moon, make a note on your calendar.(如果你真得錯(cuò)過(guò)了這輪近地滿月，在你的日歷上做個(gè)記號(hào)。)

Since the average lunar perigee is 364,397 km (226,432 mi), on March 19 the moon was about 7,820 km (4,860 mi) closer to the earth.(由于月球表面距地球的平均近地點(diǎn)距離約為364,397KM(26432米)。19日晚的超級(jí)月亮距地球的距離在此平均值的基礎(chǔ)上又縮短了近7820KM(4860米)。)

Likewise, because the size of the moon's orbit varies slightly, each perigee is not always the same distance away from Earth.(同樣，由于月亮軌道并不是一成不變，有輕微的變動(dòng)，所以每次月球運(yùn)行至近地點(diǎn)的位置與地球的間距是不一樣的。)

In order to guarantee the characteristics of frozen orbit, in-plane orbit control needs to adjust the semi-major axis, eccentricity, argument of perigee simultaneously.(為了保證凍結(jié)軌道的凍結(jié)特性，平面內(nèi)軌道控制需要對(duì)半長(zhǎng)軸、偏心率和近地點(diǎn)幅角都控制。)

Your next chance to see the Moon this large and bright, this time at full phase within only a few minutes of lunar perigee, will be next year on May 6.(下一個(gè)看見這么又大又亮的滿月的機(jī)會(huì)，將出現(xiàn)在明年的5月6日，而且它最圓的相位出現(xiàn)的時(shí)間只有近地點(diǎn)附近的數(shù)分鐘而已。)

Scientists call these perigean tides, because the moon'sclosest point to Earth is called perigee.(科學(xué)家們稱月球離地球比來(lái)的點(diǎn)為近地址，這種潮水為“近月潮”；)

This phenomenon is called "lunar perigee", or "SuperMoon".(這一現(xiàn)象被稱為”月球近地點(diǎn)”或”超級(jí)月亮”。)

The time between two passages at the perigee ( of the Moon ).(月球連續(xù)兩次經(jīng)過(guò)近地點(diǎn)所需的時(shí)間。)
