With the background of application of fuzzy control techniques to a rather typical complex control system, gas-burning water heater, theories, applications and techniques of fuzzy information processing have been studies. The obtained results include:(1) For lattice-valued logic systems based on lattice implication algebras, two dynamical lattice-valued propositional logic Lvpl and lattice-valued first-order logic Lvfl have been constructed, and some theories and methods of fuzzy reasoning have been proposed based on fuzzy set theory and multi-valued logic.(2) Some methods for designing and optimizing fuzzy control systems and some corresponding control algorithms have been proposed, and some new theories and methods for fuzzy control rule base and fuzzy control system performance analysis have been introduced.(3) 6 fuzzy control systems have been developed, and some difficult problems on craft of manufacture, batch consistency, quality stability, installation and main

本项目以模糊控制技术用于燃气热水器这一较典型的复杂控制系统为应用背景，在模糊信息处理的理论、应用和技术三个层次开展了相关的研究工作：(1)进一步研究了基于格蕴涵代数的格值逻辑系统，建立了两种动态的格值命题逻辑Lvpl和格值一阶逻辑Lvfl，并基于模糊集理论和多值逻辑提出了多种模糊推理的理论与方法；(2)提出了模糊控制系统的多种设计及优化方法与控制算法，建立了模糊控制规则库和模糊控制系统性能分析的一些新理论与新方法；(3)研制完成了6个模糊控制系统，还特别解决了模糊控制燃气热水器和智能控制燃气热水器在产业化过程中的生产工艺、批量一致、质量稳定、安装维修和性能价格等一系列难题，做好了批量生产前的技术准备，现已小批量生产。

After four hot-cakes, eight strips of bacon, and all but two small glassfuls of the pitcher of milk, I complained of hunger, so she made me three eggs and a half loaf of toast from home-baked bread.

吃完四个煎饼，八条熏肉，牛奶喝得只剩两小杯后，我还在嚷饿，于是她又给我做了三个蛋，并拿家里烤的面包做了半条吐司。

A two-year field experiment was conducted to investigate ammonia volatilization from Gleyed paddy soil in the Taihu Lake region. The experiment was designed to have four N levels 0, 180, 255, 330 kg hm^(-2 and four P205 levels 0, 30, 90, 180 kg hm^(-2, forming six NP combinations (CK-N0P0, LN-N180P90, OPT-N255P90, LP-N255P30, HP-N255P180 and HN-N330P90). Ammonia volatilization was measured with the enclosure method.

在太湖地区乌栅土上，采用田间小区试验连续两年研究了施氮量为0、180、255、330 kg hm^(-2)，施磷(P2O5)量为0、30、90、180 kg hm^(-2)的6个组合（对照N0P0低氮N180P90、优化N255P90、低磷从N255P90、高磷N255P90、高氮N330P90）以及三个施肥时期对稻田氨挥发损失的影响，氨挥发采用密闭室间歇通气法测定。
