水是地球上唯一的可变的固体,气体和液体元素。
Speaking first in generalities, suppose we have a collection of atoms, as for example, in a solid , gas or liquid.
一种元素到底属于固体、液体还是气体,要视其原子之间的相互作用而定,但它们与其它物质(如金)之间的相互作用,可相当于前一相互作用的“代理方式”。
Whether an element is a solid, a liquid or a gas depends on how its atoms interact with each other. But how they interact with other substances, such as gold, ACTS as a proxy for that behaviour.
如果2005年我们通过卡西尼探测器在土卫二南极地区发现的冰晶喷泉,实际上是土卫二内部的液体水从土卫二逃逸的出口。那么这些冰晶喷泉也许就是现在被发现的钠元素的起源地。
If the source of Enceladus' south polar geysers, discovered by Cassini in 2005, is indeed liquid water, then the geysers will transport the dissolved sodium into space.
“这些液体水深藏在土卫二的地壳内部中的岩石中,并逐渐通过过滤作用从岩石内部获得钠元素。”Lunine说。
"A liquid water layer or pocket in contact with the rock, which is deep below Enceladus' surface, will acquire sodium from the rock - essentially leaching the rock," he says.
金属镓在室温里是固体状态但是把它放在你的手上它就会融化,金属铯,元素钫这些比较稀有的元素在室温或者接近室温的情况下是液体状态的。
Gallium is solid at room temperature but will melt if held in your hand, caesium (Cs), and francium (Fr) ?the second rarest naturally occurring element, can also be liquid at or near room temperature.
当土卫二内部的液体水被喷发到土卫二寒冷的表面之后,这些液体水被寒冷的气温冻结成冰晶的同时,那些本来就存在于液体水中的钠元素也随之冻结成冰。
As the geysers reach Enceladus' frigid surface, the water freezes and some of the sodium remains trapped within the newly formed ice crystals.
优选液体阳极包括熔融盐和燃料, 优选含有相当多的元素碳。
Preferably the liquid anode comprises molten salt and a fuel, which preferably has a significant elemental carbon content.
安排的标签提供了更多的滴灌点每个元素提供更好的液体分布和更高的效率。

配以植物所需的氮、磷、钾和微量元素后,可成为多功能、高效的液体复合肥。
The nitrogen, phosphor, potassium and other trace elements added for necessary of plants, it can be multi-functional and efficient liquid compound fertilizer complex.
水(H2O)是由氢、氧两种元素构成的无机物,在常温常压下为无色无味的透明液体。
Water (H2O) is a hydrogen and oxygen are two elements of inorganic, at room temperature and pressure is a colorless odorless transparent liquid.
结果,他们发现“离子性液体离子源”是迷你推力器的核心元素。
As a result, they have discovered "ionic liquid ion sources" which are the core elements of the mini-thruster.
