Both too high and too low nutrient solution concentration could effect the growth and development of potato by aeroponic cultivation.For example,when nutrient solution concentration was 1500μs/cm or 3000μs/cm,content of photosynthetic pigments in leaves was reduced, the number of stolon were increased.

过高或过低的营养液浓度都会对马铃薯植株的生长发育造成影响，当EC值为1500μs/cm或3000μs/cm时，植株光合色素含量降低，匍匐茎形成数量少，而EC值在2000~2500μs/cm时植株生长良好，产量较高。5。

According to the development characteristics of regional caprocks,great efforts have been made to analyse the effect of it on oil and gas accumulation and preservation in different aspects. We consider regional caprocks to be the good barriers to prevent oil and gas in free phase from escaping. If uncompacted and possessing abnormal pore fluid pressure,regional caprocks are the barriers to prevent oil and gas in water dissolving phase from escaping.

根据区域性盖层的发育特征，从不同侧面对其在油气聚集与保存中所起的作用进行了深入分析，认为区域性盖层通常是阻止游离相油气逸散的良好区域物性屏障；如果其欠压实，具异常孔隙流体压力，它还可以成为阻止水溶相油气逸散的区域压力屏障；如果其再具生烃能力，还可以成为阻止扩散相天然气逸散的区域浓度屏障。

Five pieces of paleogeographic maps were made out with modern stratigraphic principles and sedimantary system method. It is shown by the maps that in the beginning of the Changzhougou time the Yanshan Region was occupied by alluvial environment with paleoriver flowing northeast, in the middle of the Changzhougou time a transgression changed whole Yanshan Region into shoreline-shallow sea environment gradually, and sedimentary boundary extended so continuously that by the Gaoyuzhuang time it had overpassed far beyond the Yanshan Region.

在缺乏良好等时面的情况下，本文依据现代地层学原理和沉积体系分析法编制了常州沟组初期与中期，串岭沟组初期，大红峪组初期，及高于庄组初期燕山地区的岩相古地理图，示意了燕山地区在长城纪时由冲积扇-河流为主的陆地环境向滨海-浅海环境的演变过程，并揭示了沉积区域不断扩大的趋势，表明常州沟组初期，以蓟县-宽城为轴线发育了冲积相组，海岸线可能在燕山以北，常州沟组中期发生海侵，沉积区扩大至整个燕山地区，大红峪组时海盆范围继续扩大，高于庄组时，沉积边界已远远超出燕山地区。
