Accordance with volume of biogas actually using requirement so that actualize supporting facilities, it can keep the pressure contant of biogas using for long time, the floating cover upside of body be pressurized, when the floating cover biogas digester fermenting to produce biogas will drive the soft PVC floating cover rising up with biogas storage, if user make use of biogas in case of biogas stove which the biogas pressure will be drop below in conjunction with floating cover will synchronous drop, when the floating cover has full of biogas which supernumerary of biogas automatic overflow to outside from bottom side of floating cover, it can not be appear with over high pressure thereby cause the tympanites of floating cove burst or biogas pipe burst and never has such phenomenon happen, the floating cove type biogas digester has reliable safe security.

根据沼气实际使用需求用量来做相应配置，可以保持长期在恒压状态沼气气压，浮罩顶部是密封的，当浮罩式沼气池发酵时所产生的沼气使浮罩上升并储存沼气，如果用户在用沼气炉灶用气时沼气压力将随之下降的同时浮罩也随着气压的下降而降低，当浮罩充满沼气时多余的沼气会自动从浮罩底部溢出，不会出现因气压过高造成鼓池、爆裂或爆管现象发生。浮罩式沼气池具有非常可靠的安全保障。

The influence environment on design of cover designs, the most influential for what has been designed to the creator, the influence of managing in fine arts , design , literature environment and magazine's management and attribute and publisher second place, the influence of politics , economy , fashion and amusement culture takes second place again.

时代环境对封面设计的影响，以设计创作者的影响最大，美术、设计、文学环境与杂志经营、属性与发行人的影响次之，政治、经济、流行及娱乐文化的影响又次之；其中「插图」的题材与时代环境最具关连，是促成风格形式表现的重要关键，其影响封面的因素多是间接而非直接的，也并非刻意或单一的介入；而封面对环境是有所影响但并不是短时间就可看出的，象徵时代环境和封面设计间之互动关系是复杂的。

Again, I maintain that we should use the flexural-tensile strain and the vertical shearing stress of the bottom of cover of the joint as the target for the design of the cover structure of asphalt on the old cement concrete. In addition, on the basis of much theoretical analysis, I preliminarily put forward to a designing methods to anchor the old cement concrete road by using dog irons made of iron bars and then covering it using asphalt concrete structure. Finally, through selecting the plan of the cover of the road to be experimented, and making a detailed introduction to the techniques of construction according to the result of theoretical analysis, I know that after anchoring the slabs close to each other with dog irons made of iron, and then cover them using asphalt cement concrete has an obvious effect on preventing and slowing down the reflection cracks in the bituminous concrete skin coat over the old road.

在大量分析的基础上提出了马钉锚固罩面结构中相邻两块水泥混凝土板接缝处的相对水平位移、相对垂直位移、接缝处沥青层底部的弯拉应变和剪应变的计算公式；再次，提出了采用接缝处罩面层底部的弯拉应变、垂直剪应变作为旧水泥混凝土路面上沥青混凝土罩面结构的设计指标，并在大量理论分析的基础上，初步提出了马钉锚固旧水泥混凝土板后沥青混凝土罩面结构的设计方法；最后，根据理论分析的结果，选定试验路的罩面方案，并对其施工工艺进行了详细的介绍，表明采用钢筋马钉锚固相邻混凝土板后，再进行沥青混凝土罩面的方法在防止或减缓罩面层反射裂缝方面具有明显的效果。
