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 wet weather may be encountered when comparing species typical scenario is the beginning of the display screen of a very vague until after half an hour to boot normal, due to the impact of air humidity inside the display, the display must be turned on after the warm-up period of time to work properly.

在天气潮湿的时候有可能会遇到种比较典型的情况就是显示器一开始的时候屏幕非常模糊要开机半个小时以后才会正常，原因是空气潮湿影响了显示器内部，显示器开启后必须预热一段时间才能正常工作。

The " cloud " in the " between pink clouds of white emperor of decline of day of the " in the poem is vapor is encountered cold the Xiaoshui that form drips to gather and be become in float of empty horizontally pivoted hung, the hill of river of liquefacient;" a thousand li in belonging to states of matter to change returns the " in " one day one day to return ", the rate that shows a boat is very rapid,"What " of a thousand li points to is distance,"What a day of " points to is caw of simian sound of time;" two sides does not live ", simian ululation is by simian vocal cords vibration generation, canoe of the;" in relying on air to upload person ear from the bank already crossed " of 10 thousand heavy hill, be it is with hill consult content, the boat is moving,"Canoe " explained the quality of the boat is lesser, and still got water is opposite it up buoyancy.

诗中"朝辞白帝彩云间"中的"云"是水蒸气遇冷形成的小水滴在空中悬浮聚集而成的，属于物态变化中的液化；"千里江陵一日还"中的"一日还"，说明船的速度很快，"千里"指的是路程，"一日"指的是时间；"两岸猿声啼不住"，猿啼声是由猿的声带振动而产生的，并靠空气从岸边上传到人耳中；"轻舟已过万重山"，是以山为参照物，船在运动，"轻舟"说明了船的质量较小，并且还受到了水对它向上的浮力。

Orthogonal experiment under special condition showed that modifier M has marked effect on properties of no bake sand. Other factors such as modifier B,phosphate concentration and aluminum hydroxide have some impact on properties of binder. It can be found by experiments that strengths of no bake sand are raised notably by binder that modified by modifier B. Modifier B can reduce the strength of no bake sand at high room temperature apart from condition of low room temperature that it can accelerate the reaction and strengthen the sand. Modest content of modifier M in binder has some improvement to anti-wettability of sand. But modifier B has not such notable effect. Electronic microscope shows that near cracks in no bake product there are fibrous shape substances formed when the samples are moistured in high humidity air for sometime.

通过改性剂B对粘结剂自硬砂的性能影响试验发现，改性剂B能显著提高粘结剂自硬砂的强度，在0℃左右很低的环境温度下改性剂M有利于提高自硬砂的反应速度和砂型强度外，但在较高环境温度下，改性剂M均降低粘结剂自硬砂的强度，但是适量的改性剂M有利于改善自硬砂的抗吸湿性，而改性剂B对于改善自硬砂的抗吸湿性的作用不如改性剂M明显，电镜观察发现抗吸湿性较好的自硬砂在高湿度下存放一定时间后，在粘结膜裂纹处会形成一种绒毛状物质，该物质对裂纹具有愈合作用，这种绒毛状物质中具有改性剂M中的某种成分，且含量很高，由此说明改性剂M对提高抗吸湿性有利。

His advanced idea on folk literature and "enthusiasm for folk songs" have fairly great influence on his poetry creation: first, Huang is good at absorbing the nutrition of the folk songs, thus has poured new vigor to his writing; second, he absorbs the idea of "true affection" in folk songs, and advocates that the writing of poems should express one's aspirations, and be true in emotion and desire; third, the "enthusiasm for folk songs" has entrusted the balladic air to some of his poems.

他进步的民间文学观和&民歌情结&对他的诗歌创作有着较大的影响：一、黄遵宪善于吸取民歌的营养，为自己的创作注入了新的活力；二、他吸取民歌中的&情真&说，主张写诗要情真、意真、抒发我之心声；三、&民歌情结&赋予黄遵宪部分诗篇以民歌风味。

These riders take pleasure in the whole thing about snowboarding: the imagination that can only be understood sliding the half-pipe, the astounding feel of carving a turn on slopes, the sense of flight you get at lift-off from the big-air jump, and the feel of freedom one gets sliding on new snow.
