中文摘要：

使用强制触发的方法，清华大学高能中心的研究人员首次在日本超级神冈实验的纯水探测介质中观察到了中子俘获寿命曲线。本文讨论强制触发的实现原理和强制触发电子学模块的具体设计，并对实验过程和结果进行了讨论。

英文摘要：

A forced trigger method is proposed to record emitted 2. 2MeV 7 candidates from neutron capture in pure water for Super karniokande neutrino experiment. The design of the forced trigger module is described in this article; the result is also presented and discussed.
