双语例句
- The red emission of Si-base films is related to the density of the nanometer grains and the number of the grains in the bohr radius.
硅基薄膜的红光发射与纳米晶硅密度及波尔半径内晶粒数目有着密切的关系。 - If the definition of Bohr radius included the reduced mass of hydrogen, it would be necessary to include a more complex adjustment in equations relating to other atoms.
如果玻尔半径包括了氢原子的约化质量，就有需要加入一个复杂的修正值来使方程适用于其他原子。 - We can make some substitutions here using some of the derivation on the previous board which will give us the Planck constant divided by2 pi mass of the electron times the Bohr radius.
在这里我们也可以，用我以前在黑板上写过的一些词来取代它，得到的是普朗克常数除以2π电子质量，再乘以波尔半径。 - And remember, a nought, that's just the Bohr radius, that's all we need to worry about.
记住a0就是波尔半径，我们要记住这点。 - So if we superimpose our radial probability distribution onto the Bohr radius, we see it's much more complicated than just having a discreet radius.
为波尔半径，这其实比分立的轨道，要复杂很多，我们可以有任何的半径，但有些半径的概率。 - Bohr radius was the radius of the circle in which the electron moved in the ground state of the hydrogen atom, according to the Bohr theory.
根据玻尔理论，玻尔半径是在基态氢原子中电子运动的圆周半径。 - And this quantity is termed the Bohr radius.
而这个量被叫做，Bohr，半径。 - While the Bohr model does not correctly describe an atom, the Bohr radius keeps its physical meaning as a characteristic size of the electron cloud in a full quantum-mechanical description.
尽管玻尔模型并没有正确地描述原子，玻尔半径还是保有了它的物理意义，代表着电子云大小的完全量子力学描述。 - The Bohr radius of the electron is one of a trio of related units of length, the other two being the Compton wavelength of the electron and the classical electron radius.
电子的玻尔半径是一组三个互相关联的长度单位中的一个，其他两个是电子的康普顿波长及经典电子半径。 - We prove that replacing the electron mass by the reduced mass in Bohr's equation for the radius of the electron does not yield Bohr's orbit radius, but rather the electron ( orbit particle)-proton ( nucleus) separation.
证明了：在玻尔的电子轨道半径表达式中，用折合质量代换电子质量不能求得轨道半径，只能求得电子（轨道粒子）&质子（原子核）之间的距离。 - When the size of the nanocrystals decreases to the exciton Bohr radius, the energy level becomes discrete from the continuum, and the energy gap increases as the crystal boundary significantly modifies electron distribution, showing a quantum confinement effect.
当微粒尺寸减小至激子的玻尔半径时，由于晶界改变了电子分布状态，相应的电子能态从连续的能带变为分立的能级结构，使带隙变宽，表现出量子限域效应。 - As one of the III-V group materials, InAs ( indium arsenide) is an important narrow direct band semiconductor. It has high electron mobility, low electron effective mass and a large exciton Bohr radius.
InAs是Ⅲ-Ⅴ族材料中一种重要的窄直接带隙半导体，具有高电子迁移率，低有效质量以及很大的激子玻尔半径。 - The exciton Bohr radius of Ge is far greater than that of silicon, indicating that obvious quantum size effect will appear in Ge.
Ge的激子玻尔半径远大于硅，表明其具有更为显著的量子尺寸效应。
