英语翻译
有点高不清楚是什么意思
1.it is the only body in solar system known to have an orbital or rotational resonance with an ratio other than 1:1
2.have relatively low density than other terrestrial planet (即rocky planet)
indicates that that its core contains large fraction of sulfur in addition of iron
上面的是水星的特点之一下面的是火星的特点之一
还有这个jupiter have high velocity winds which are confined in wide bands of latitude
the wind blows in opposite direction in adjacent bands

我对天文学术语拿捏不是很准,只能解释一下吧,供参考：
1.水星是人们在太阳系中唯一所知的具有轨道/旋转共振率不成1:1的星球.
原文参考：Until 1962 it was thought that Mercury's "day" was the same length as its "year" so as to keep that same face to the Sun much as the Moon does to the Earth.But this was shown to be false in 1965 by doppler radar observations.It is now known that Mercury rotates three times in two of its years.Mercury is the only body in the solar system known to have an orbital/rotational resonance with a ratio other than 1:1.
2.火星与其它类地行星相比则具有相当低的密度,这就表明其核心部分蕴藏着大量的硫和铁.
原文参考：The interior of Mars is known only by inference from data about the surface and the bulk statistics of the planet.The most likely scenario is a dense core about 1700 km in radius,a molten rocky mantle somewhat denser than the Earth's and a thin crust.Mars' relatively low density compared to the other terrestrial planets indicates that its core probably contains a relatively large fraction of sulfur in addition to iron (iron and iron sulfide).The mean density of the planet is less than that of Earth.In other words,Mars weighs 3.9 times as much as an equal volume of water would weigh.In contrast,the specific gravity of Earth is 5.5.Since a planet becomes less dense from its core towards its outer layers,the mean density of Mars is roughly equal to that of the outer layers of Earth.
再问： 哇，厉害，谢谢你，这个也能帮我解释一下吗？？ 我准备在外国考大学，有些看不明白jupiter have high velocity winds which are confined in wide bands of latitude ，the wind blows in opposite direction in adjacent bands
再答： 解释一下：木星上的风速很高，其活动范围很是宽广，毗邻区域间的风呈相反的方向运动。 原文参考：Jupiter and the other gas planets have high velocity winds which are confined in wide bands of latitude. The winds blow in opposite directions in adjacent bands. Slight chemical and temperature differences between these bands are responsible for the colored bands that dominate the planet's appearance. The light colored bands are called zones, the dark ones belts. The data from the Galileo probe indicate that the winds are even faster than expected (more than 400 mph) and extend down into as far as the probe was able to observe. Jupiter's atmosphere was also found to be quite turbulent. This indicates that Jupiter's winds are driven in large part by its internal heat rather than from solar input as on Earth.
