主要内容及结论：1充氡后利用计算机连续进行电离电流累积测量，得到了精细的电流随时间的变化曲线，可清楚看出氡及其子体的生成衰变造成的电离电流的生长—稳定—衰减过程，与理论计算值进行了比较，由电离电流衰减速度的变化得出氡吸附作用的影响，并测量到电离室冲洗后氡的反扩散现象；2由已知活度的标准源定出相对测量的刻度系数K值，K=24.62 Bq／pA，对同一个监测源以半年为周期进行多次测量后得出稳定性符合要求；3通过测量电离电流和气压的关系曲线以及不同气压下的饱和曲线，确定了常规的工作条件；4测量了盐酸清洗电离室内表面降低本底的效果；5不确定度分析表明相对测氡的扩展不确定度(k=2)小于5％，由本底涨落得出探测下限为0.5 Bq；6理论上对壁损失修正进行了计算，实验上保持电离室工作在饱和区的情况下，测量了不同气压下电离电流的变化，从中得出了壁损失随气压变化的规律，可以看出，电离电流的实测值和计算值随气压变化规律基本一致；当气压大于125 kPa时，端效应等其它因素造成的影响不大于2％，因而在此工作条件下，测量电离电流后通过计算修正壁损失可以实现近似的绝对测氡，提出了进一步提高绝对测量准确度的方法。

First, UWPBL model(The University of Washington Planetary Boundary Layer Model) is used to retrieve typhoon's sea level pressure from sea surface winds data of SeaWinds which aboard on QuikSCAT and these strength results are analyzed. Then the variational method is applied to decompose the sea surface winds field into two parts: the vortex and irrotational environmental flow field, the UWPBL model is used again to retrieve ShanShan and YaGi typhoons' sea level pressure from the vortex flow field, the results of typhoon's central positions are analyzed by comparing the results with the results of direct retrieving, NCEP's data and typhoon annual reports. It turns out that the accuracy of the typhoon's sea level pressure central position has been obviously improved, This method offers a new idea for the study of typhoon from microwave scatterometer data.

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。
