We establish the quantum theory of the one-mode micromaser injected by ultracold V-type three-level atoms with atomic coherence, and discuss the properties of the emission probability, the photon statistics, the spectrum and the velocity selection. We find the following results. There are two sets of peaks in the plot of the emission probability versus the cavity length. The injected atomic coherence can deeply affect the values of the two sets of peaks and the unresonant platform.

为此，我们对此做了一系列深入研究，本文的主体内容有二：第一，研究了N型四能级原子系统中的原子相干效应。

When the detuning between the atomic transition frequency and the frequency of each mode is much large, the probability of atomic transition can be neglected.

当原子上、下能级的跃迁频率与腔场的每个模的频率都失谐较大时，原子的跃迁几率可以忽略。

Periodic Table Ⅵ B family silver-white metallic luster of the solid metal transition element, atomic number Z = 74, atomic weight of 18385, chemical symbol W, there are five kinds of natural F stable isotopes, 18174W, 18274W, 18374W, 18474W, 18574W and eight kinds of radioisotopes .

周期表中ⅥB族银白色金属光泽的固体金属过渡元素，原子序数Z＝74，原子量18385，化学符号W，有五种自然F 稳定同位素，18174W、18274W、18374W、18474W、18574W和八种放射性同位素。

The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.

本文首先对针尖—基体模型的弹塑性接触机理进行了深入研究，指出在原子水平上材料的塑性屈服仍由Von Mises准则控制；对平底锥冲头粘着接触的模拟表明，除了在接触区边缘附近有一定差别外，接触力学方法在接触区内几个晶格常数范围内仍能给出令人满意的结果；由于原子台阶效应，加载与卸载曲线不重合，出现粘着滞后，证实了Pollock关于具有纳米阶梯结构的球体粘着滞后现象的推测。
