On the 3 + 1 dimensional lattice gauge theory with massless fermions-a study on the tunnel effect between the θ vacua

3+1维含无质量费米子的格点规范理论&θ 真空隧道效应的研究

The static atom in Unruh and Hartle-Hawking vacua would feel thermal radiation and the temperature it feels satisfies the Tolman relation .

Unruh 真空 和 Hartle-Hawking 真空中的原子将感受到时空中的热辐射，原子感受到的温度满足Tolman关系。

These may completely change or do away with the landscape of string vacua or with the cascade of bubbles that populate the landscape .

这些也许将完全改变或去除弦 真空 的 地景，或者 放弃在 地景上 聚 集成瀑布般的泡泡。

The radiation spectrum for relativistic electron moving along curved spiral curve in plasmas is calculated and also the formula of total energy emitted by a relativistic electron in vacua is derived .

从运动 荷 电 粒子产生的流出 发，导出相对论电子和相对论电子 集在等离子体及 真空 情况下曲率辐射的能量谱及辐射总能量，分析了等离子体对辐射的影响。

In measuring the photovoltage spectra at room temperature in different vacua it is found that the photovoltage of AlGaAs / GaAs multiple quantum wells is very sensitive to vacua .

通过测量在不同 真空 度中的室温光电压谱，发现AlGaAs／GaAs多量子阱的光电压对真空度很敏感。

Consequently as time goes on different vacua can come into existence .

所以，随 著时间的进行，不同的 真空 便 不断 地 诞生。

Similarly only a small fraction of the stable vacua are hospitable to life .

同样地，只有稳定 真空的一小部份才适合生命。
