- Figure 2: The picture are the right is of the heme group in hemoglobin and shows the Fe(II) iron atom. 血红蛋白和肌红蛋白是球蛋白,其结构为血红素中的铁在卟啉环平面的上下方再与配位体进行配位,达到配位数为六的化合物。
- "Heme, a complex heterocyclic compound, is an organic molecule derived from porphyrin with an iron atom at the centre. 血红素(一种复杂的杂环化合物)是来自中心含铁原子的的一种有机分子。
- Iron atoms have 26 electrons in different orbitals around their nuclei. 铁原子在围绕其原子核的不同轨道上有26个电子。
- Transmitting X rays through hemoglobin at the energy that would detach an electron from an iron atom enabled us to calculate the distance between iron and nitrogen atoms as the hemoglobin bound more and more oxygen. 让能量足以使一个电子脱离铁原子的X射线通过血红蛋白,我们就能计算出当血红蛋白同越来越多的氧结合时铁原子与氮原子之间的距离。
- When the X-rays reach the cloud, they collide with iron atoms, kicking out electrons that are close to the atomic nucleus. 当X射线抵达星云便与铁原子发生碰撞,将靠近原子核的电子敲出。
- Normally, the measured spectral line for the superheated iron atoms would show up as a symmetrical peak. 通常,所测得的超高温铁原子光谱线会显示出一个均匀的尖顶。
- Their next goal is to create element 120 by beaming iron atoms (26 protons) at a plutonium target (which has 94 protons). 他们的下一个目标是创造120号元素,使用铁原子(26个质子)轰击钚(94个质子)。--钚(读音:布)。
- Because of the iron atoms, ferritin molecules are able to scatter a beam of electrons and thus can be visualized in electron microscope. 因为铁原子,铁蛋白分子可以分散成电子带,就可以在电子显微镜下被显像。
- To get a better grasp of the size and distribution of material in this disc, astronomers used XMM-Newton to search for X-rays emitted by iron atoms. 为了获得一个更好的了解旋盘中物质的分布及尺寸情况的机会,天文学家使用XMM-牛顿来搜寻铁原子发射出的X射线。
- The atom bomb is of catholic concern. 原子弹受到普遍的关注。
- That cannot get up an atom of sympathy for them. 那并不能激发起人们对他们的丝毫同情。
- We wanted to see whether the speed of binding oxygen affected the distances between the iron atoms and the nitrogen atoms to which they are also bound . 我们希望能知道,同氧结合的速率到底是否影响到铁原子与同样和铁原子相结合的氮原子之间的距离。
