玻尔半径

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。

The exciton Bohr radius of Ge is far greater than that of silicon , indicating that obvious quantum size effect will appear in Ge .

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。

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 .

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。

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 .

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。

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 .

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。

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 .

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。

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 .

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。

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 .

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。

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 .
