They used two atomic clocks, synchronized them, and placed one on a plane, while the other stayed in the same location on Earth. 他们使用两个原子钟,将时间调成一致。其中一个被放在飞机上,而另一个则置于地球上的原来地方。
We calculate the atomic and electronic structure of β_SiC ( 001)_ ( 2 × 1) using augmented plane wave and local orbital ( APW+ LO) method. 利用缀加平面波加局域轨道(APW+LO)的第一性原理方法计算了βSiC(001)(2×1)表面的原子及电子结构。
We present a theoretical calculation on the atomic and electronic structure of α SiC and its non polar ( 1010) surface using the full potential linear augmented plane wave ( FPLAPW) approach. 用全势缀加平面波方法(FPLAPW)计算了αSiC及其非极性(1010)表面的原子与电子结构。
The atomic arrangement at the plane of the interface is analyzed based on the image characteristics. Possible bonding configurations are discussed. The results suggest that interface formation is first driven by charge balance. 通过对界面原子排列的分析,界面化学键构型的讨论,结果表明电荷平衡原理是界面形成首要遵从的原则。
