水面上的

We got that,the charged particles be binded in this field,and canonly move along the magnetic line of force as spiral motion and the positive charges andnegative charges moved in opposite direction which be fromed the big molecular groups thatbe hardly absorption,by means of incrustation preventing.

讨论了轴对称非均匀磁场对带电粒子的作用，分析了"磁约束"对防垢、除垢的微观机理，指出满足磁约束理论的轴对称非均匀磁场的防垢，除垢效果好的原因，正是由于在这种磁场中，带电粒子的运动被约束在一定磁面上的某一磁感应线附近做以该磁感应线为中心的螺旋运动，且正、负离子的回旋方向相反，从而形成内部相互作用较弱的大分子簇团不易吸附在管壁上，达到防垢目的；磁化水的渗透压较大，可起到除垢效果。

A bridge spanned it midway and from there to its lower end, where an amber-hued belt of sand-hills shut it in from the dark blue gulf beyond, the water was a glory of many shifting hues--the most spiritual shadings of crocus and rose and ethereal green, with other elusive tintings for which no name has ever been found.

桥与沙丘之间的水面上，红、橙、黄、绿、青、蓝、紫以及各种叫不出名的颜色交织在一起，变化多端，绚烂多彩，简直就是个色彩的海洋，让人找不到适当的词来形容它。

Rock also comes from volcanoes in other forms, including ash (finely powdered rock that looks like dark smoke coming from the volcano), cinders, and pumice (light-weight rock that is full of air bubbles and is formed in explosive volcanic eruptions - this type of rock can float on water).

岩石也可以在火山上以其他形式迸出，包括灰烬（从火山中看上去像烟的粉末状的岩石），熔渣，和轻石（轻的充满空气泡泡的岩石，从爆发的火山中形成的--这种岩石可以浮在水面上）。

Plants like duckweeds float on the surface of still and slow-moving waters, while those with roots and flexible stems can stand in swift-flowing streams.

像浮萍类的植物，它们漂浮在静止和缓慢流动的水面上，而那些有根而且茎干柔韧的植物则能在快速流动的溪流中生长。

Plants like duckweeds float on the surface of still and slow-moving waters, while those with roots and flexible stems can stand in swift-flowing streams.

浮萍类的植物漂浮在静止和慢慢移动的水面上，而有根和软茎的植物可以立在快速流动的水流中。

Plants like duckweeds float on the surface of still and slow-moving waters, while those with roots and flexible stems can stand in swift-flowing streams.

浮萍的植物漂浮在寂静或者流动缓慢的水面上，而那些有根系和柔韧茎干的植物就可以扎根在湍急的河川中。

Three teams traveled from Beijing to Hawaii for the game's final set of competitions, which involved preparing pigs for luaus and racing on personal watercrafts to find clues floating on the water.

三个小组专程从北京到夏威夷的游戏的最后一盘的比赛，其中包括准备猪的luaus和个人船舶赛车找到线索浮在水面上。

A swimmer with a snorkel can still breathe, but notice that snorkelers float right on the top. Were they to try sinking underneath, even a moderate amount, the same thing would happen.

带了一个通气管的游泳者仍然能够呼吸，但是有一点要注意的是，这是游泳者刚好漂浮在水面上，如果他们尝试这潜的深一点的话，即便是慢慢的潜入，呼吸还是很困难。

At night, the multicolored lights shines on the water, the fish had his head above water, in the lighting dance, frog side accompaniment to cricket in the next song, the square along with wonderful music, people danced a Waving Dance ...... now Qing river can be exuberant.

到了晚上，五彩的灯光照在水面上，鱼儿们把头露出水面，在灯光下舞蹈，青蛙在旁边伴奏，蛐蛐在旁边歌唱，广场上的人们随着美妙的音乐跳起了摆手舞……现在的清江河可热闹了。

In this dark, silent place, thousands of tiny living lights belonging to glowworms dot the ceiling and walls. They light the way as visitors glide quietly beneath them on dark water that reflects the lights from the glowworms.

在这个漆黑而静谧的地方，几千只萤火虫发出的微弱光芒点缀着洞顶和洞壁，光芒照映在深色的水面上，为下方静静滑过的游客照路。
