Trilby Lundberg, publisher of the Lundberg Survey, said the new record high comes from an upward trend fueled by higher crude oil prices globally, increased demand for gas caused by economic growth in the United States and increased refinery costs resulting from seasonal changes in refinery processes mandated by environmental rules.

Lundberg Survey分析师Trilby Lundberg称：汽油价格升高主要原因为全球原油价格升高导致燃料价格上扬；美国经济增长对汽油需求增加；环境因素引起精炼工艺季节性变化所导致的提炼成本上升。

However, the contour fields below 500 mb suffer small change. This situation is related to the dynamical factors near the tropopause.

After that the territor ial extensional stress field caused by the plates movement and the mantle upheave etc. makes the Yishu fault system keep on cutting downward tend to form rift valley. The tectonism causes the fairly large-scale invasion of the small neutral -partial alkaline rock-bodies and the gold mineralization in the Linyi area.

燕山中期板块俯冲运动和地幔上涌等因素引起的区域性拉张作用使沂沭断裂继续向下深切张裂，向裂谷性质演化，造成沂南、临沂等地区较大规模中性偏碱性次火山岩型小岩体的侵入和火山喷发，在火山机构内或围绕次火山岩小岩体形成与中性偏碱性次火山岩有关的次火山岩型金矿化。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
