In order to verify the validity of the mathematical models and the calculation method, a series of experiments on the performance of an air-conditioner under variable conditions was conducted in the psychrometric rooms.The performances of the proto type under the different inlet air temperature of the condenser and evaporator, as well as the different face velocity of the condenser and evaporator was measured.

为了验证数学模型及计算方法的正确性，在焓差法空调器性能实验台上对一台房间空调器变工况性能进行了实验研究，测量了该空调器在不同的蒸发器和冷凝器进口空气温度、蒸发器和冷凝器迎面风速下的工作特性。

In order to prove the reliability, test studies have been primarily carried out in the indoor soil bin. The data of the vehicle driving state parameters under the same or different terrain are analyzed. The process curves are compared by different control schemes. The theoretical model of the optimum driving state is reliable and fuzzy control scheme is feasible. The disturbances and unknown factors of control system are analyzed. Test results prove that the half-tracked air-cushion vehicle can drive steadily under control of the computer. At the same time the sensors used to measure soil mechanics characteristics on line need to be developed. And it is the important problem to be solved in the future study. The necessary regulation and correction are put up. So the studies in this paper provide some instruction for the further research work.

为了验证本文提出的最佳工作状态及最佳垫压理论，并分析控制系统的可靠性和稳定性，本文在半履带式气垫车的模型车上，在室内土槽中进行了初步的实车性能和理论验证试验，考察了在同种和不同土壤条件下气垫车的行驶状态参数的测量数据，比较了采用不同控制方法下的过程曲线，验证了最佳工作状态的理论模型和模糊控制系统方案的可行性与可靠性，从而保证了采用自整定模糊PID控制器能够使半履带式气垫车在稳定行驶最佳工作状态下；同时通过试验研究，分析了系统中各干扰与未知因素，对控制方案进行了相应的调整和修正，为今后进一步的研究工作提供了一定的指导。

In this paper, through a series of experiments, two series of quaternary-ammounium Gemini surfactants were synthesized, namely the pair alkylene double quaternary ammonium salt surfactant m-s-m·2Br and the pair the alkylene double quaternary ammonium salt surfactant -s-·2Br. We has carried on the attribute with the infrared spectrum to its structure, and to affected the factor which the synthesis pair the alkylene double quaternary ammonium salt surfactant responded to carry on the discussion. We has discovered the synthesis pair the ethylene double quaternary ammonium salt surfactant m-2-m·2Br optimum condition: The bromo alkane and a tetramethyl ethylene diamine mole of ratio is 3.0: 1.0, makes the solvent by the ethyl alcohol, 80℃ under responds for 48 hours in the backflow temperature; Synthesis pair alkylene double quaternary ammonium salt surfactant 12-S-12 ·2Br optimum condition: 12 tertiary amine and 1, 3- propylene dibromide (1, 4- two bromines butane) a mole of ratio is 2.2: 1.0, makes the solvent by the ethyl alcohol, responds for 48 hours in the constant temperature 80 ℃ under backflow.
