So in this paper based on the characteristics and the optimum state theory of the vehicle, some kinds of control schemes are compared and discussed, and the fuzzy PID control scheme is adopted at last. The relation between air-cushion pressure and fan rotational speed on the optimum driving state is studied. The cushion pressure is used as controlled variable and the fan revolution is used as regulated variable. And transducer and fan motor are actuators.Based on the structure and operating properties of half-tracked air-cushion vehicle, the control system scheme and structure are presented. A control scheme using the self-tuning PID fuzzy logical controller is adopted. Fuzzy rules are set up and some researches have been done for fuzzy tuning method. At the same time the real-time measurement scheme by computer control is proposed, and electric circuits are designed. In the control system of half-tracked air-cushion vehicle cushion pressure P〓 is used as controlled variable and the fan speed n〓 as regulated variable.

Elementary discussion on ventilation mode of the power house of hydropower station in river channel;2. According to the State Standard of Indoor Air Quality GB/T18883-2002,the air pollutants in the passenger car cabin were measured,and the influence of temperature,the type of car,the time since the manufacture date and the ventilation mode on the air quality was evaluated.

5倍；车内污染物的质量浓度随时间延长不断衰减，约10 d后趋于稳定；发动机运转时客车内污染物质量浓度升高，车内的空气质量变差；自然通风与循环通风均可使车内污染物质量浓度迅速下降，但自然通风方式效果更好。

This paper analyzed the air-conditioning system of one specific office building in Beijing, calculating the costs of unit cold and heat exergy and the unit cold and heat capacity of adopting GSHP system and air source heat pump system separately. With these numbers as standard for evaluation and comparison, it supports the conclusion that adopting GSHP system is better than adopting air source heat pump system and the heat economics analyzing method is more accurate than that based on energy.
