查询词典 Earth

The earth has a magnetic north pole and a magnetic south pole. These poles are close to, but not exactly at, the earth's axis of rotation . What's more, they are constantly moving!

地球也有南、北两磁极，这两极很接近地球自转的轴线，但并不完全相同；再者，它们不断地在改变位置！

Photo of the Day: Exquisite Earth This lonely mangrove clings to the earth with its massive roots.

The effects of different lead concentration in meadow brown earth, red earth and gray limestone soil on wetland rice growth and its uptake of lead were investigated. The results showed that all treatments did not significantly change the biomass of wet...

水稻吸收的Pb与土壤中的添加Pb、总量Pb和DTPA可提取Pb含量之间均有着极显著的相关性，并由此计算了Pb的表观临界含量，其中湖北土对Pb的污染十分敏感(表观临界含量为79mgPb·kg-1)。

Likewise, it would appear a reasonable hypothesis that the Earth has also been subjected to meteoroid bombardment in the past, and that very large bodies struck the Earth early in its geological history.

同样地，地球也经历过陨石的撞击就显得是一个合理的假设，而且在他的早期地质年代里有非常大的星体撞击过地球。

Likewise,诸如, it would appear a reasonable hypothesis that the Earth has also been subjected to meteoroid bombardment in the past, and that very large bodies struck the Earth early in its geological history.

它显示出了一个可能的假设，地球在过去受到流星炸弹，而那非常大的实体打击地球早在它的地质历史。

Given the possibility of ghost water that covers part of the earth not covered by physical water, it cannot follow from microphysics that water covers 60% of the earth.

假设可能的水幽灵覆盖了部分物理水没有覆盖的地面，就无法从微观物理学得到水覆盖60％。

Applying this point to Jackson's argument, we can't move a priori from microphysics to the claim that water covers 60% of the earth because there is a world in which some of what counts as water is ghost water, so even if H2O covers 60% of the earth in that world, what they call 'water' will cover more.

用这一点在Jackson的论证上，我们不能从微观物理学传递先天性给'水覆盖60％'，因为有一个世界有些算作水的东西是水幽灵，所以，即使在那个世界H2O覆盖60％，他们称为"水"的东西会覆盖更多。

A preparation method of nickel oxide-base cathode of fused carbonate fuel cell is to select alkali earth metal oxide, transition metal oxide and rare-earth metal oxide, mix with carbonyl nickel powder in the proportion of 0.01-15.00 mol%, add assistant and mix even into a slurry; after the slurry is formed into a biscuit by doctor-blade casting, sinter it into a multi-porous nickel plate; dissolve lithium nitrate and cobaltous nitrate with mole ratio of Li:Co-1:1 and citric acid or PVA in the distilled water to make a solution with Li of 0.00-0.5 mol/L; immerse the multi-porous nickel plate or nickel oxide plate in the solution, keep for 10-60 minutes under vacuum below 200 millibar, then dry in an oven at 75 degrees centigrade further transfer to a crucible electric furnace preheated 650 degrees centigrade for keeping the temp.

要約 熔融碳酸盐燃料电池氧化镍基阴极的制备方法属于燃料电池领域。选取碱土金属氧化物、过渡金属氧化物和稀土金属氧化物，按0.01－15.00mol％的比例与羰基镍粉混合，加入助剂，混合均匀成浆料；混合浆料流延成型为素坯后烧结为多孔金属镍板；将摩尔比为Li∶Co＝1∶1的硝酸锂和硝酸钴以及柠檬酸或聚乙烯醇溶于蒸馏水中，制成为0.005－0.5mol/L的溶液；将多孔金属镍板或氧化镍板浸入溶液中，在真空度低于200毫巴下保持10－60分钟；置于75℃的烘箱中烘干，转移至预热到650℃坩埚电炉中保温1－10小时；将此过程重复一次或多次即可。

The Earth is mother; I am son of Earth.
