次日（2月11日）上午十点，斯蒂夫向秦若华问起了游泳池的事——自从去年交大在研究所内办了运动会的游泳项目后，泳池就没有开过了。
面对斯蒂夫的询问，秦若华给出了简单的答复：“我们不觉得现在的安排有什么不合理的。为了调节研究所内人员要求和安全要求的需要，我们会在今天下午和晚上最后开放一次游泳池。在此之后，我们要等到2月18日以后，决定游泳池会在什么时候继续开放。斯蒂夫教授，我们总不能把已经十分紧张的、用于保护研究所安全的安保力量用在这里吧？”
于是，斯蒂夫带着想要的答复心满意足地离开了办公室。
一刻钟后，当整理完手中文件的秦若华来到夏希羽的住处时，她看见后者正在写一篇简单的英语短文。
“……Since 1980， researchers extensively used fuzzy controllers in various applications. Fuzzy controllers are a type of control system that uses fuzzy logic to handle imprecise or uncertain information. They were particularly popular in the field of industrial automation and control systems.
“Researchers utilized fuzzy controllers to improve the performance of plex systems that were difficult to model using traditional control techniques. Fuzzy controllers allowed for the incorporation of expert knowledge and linguistic rules into the control system， enabling more intuitive and human-like decision-making.
写到这里时，夏希羽思考了好一会后，才继续写后两段。
“One of the key advantages of fuzzy controllers was their ability to handle non-linear and uncertain systems. They provided a flexible framework for dealing with imprecise inputs and outputs， making them suitable for a wide range of applications.
“Researchers applied fuzzy controllers in areas such as robotics， process control， power systems， and automotive systems. They developed novel control algorithms and techniques based on fuzzy logic to address specific challenges in these domains……”
