我们在约束理论中研究了Schwinger对的产生。用全息描述法对外电场E中的产率进行了数值计算。电场存在两种临界值：i）E=E_c，在此值以上，没有势垒，粒子可以自由产生; ii）E=E_s，在此值以下，束缚弦张力控制电场，不产生电子对。我们讨论了与临界行为相关的普适指数。
We study the Schwinger pair production in confining theories. The production rate in an external electric field E is numerically evaluated by using the holographic description. There exist two kinds of critical values of the electric field, i) E=E_c, above which there is no potential barrier and particles are freely generated, ii) E=E_s, below which the confining string tension dominates the electric field and the pair production does not occur. We argue the universal exponents associated with the critical behaviors.
