Cinema apparatus functions relatively like a mirror, during a film we recognize ourselves through the on screen 'Other' and we project our egos onto that 'Other' - we superimpose ourselves onto them, going through events as they do. Film spectatorship involves the engagement of our entire body – our bodies react to the films, for example our heart rate would go up when sitting through an intense car chase scene, and we feel the natural reflex to throw up when seeing some grotesque zombies with intestines gushing out their abdomen on screen.

住："镜像阶段"是法国心理学家Jacques Lacan所推崇的一个概念，他认为新生儿在刚出生是没有自我意识，它认为自己是和母体连在一起的，又或是不知道自己已经离开子宫；而它将在第一次照镜子时，也就是看见自己的镜像时认识到自己是独立的一个个体）相似的，电影这个视觉机构也有类似镜子一样的功能，在观看电影的同时，我们通过对比银幕上和我们不同的其他人，进而肯定和巩固我们的自主形象和意识。

When comparing the results of the Fe2+/HPCD flushing through S2O82- fluid sparging curtain system to the S2O82-/HPCD flushing through Fe2+ sparging curtain system, the former system resulted in a higher rate of chloride formation. Therefore, the S2O82-/HPCD flushing through Fe2+ fluid sparging curtain may offer a potential way for remediation of TCE-DNAPL contamination.

Based on the data analysis and numerical simulation, the Arctic sea ice climate variability was researched, the result were as following:(1) The analysis on the seasonal cycle of the Arctic Ocean and atmosphere showed that: The seasonal surface wind is somewhat trade wind like in some regions in the Arctic. The surface air temperature is robustly determined from the underlying environments such as sea ice and Greenland glaciers. In the sea ice region the precipitation rate is larger than that of evaporation. Furthermore, the Arctic Ocean hydrology is profoundly influenced by the surrounding rivers discharge. These are the decisive factors on the ocean salinity pattern. Sea ice flux through the Fram Strait is larger in winter than in summer. From the 40s in the 20th century on, the ice volume flux has an increasing trend. The Arctic rivers flood season is about the melt period, the winter rivers discharge has a significant increasing. Correlation analysis shows that 7 to 10 years is a characteristic time scale that rivers discharge leads Fram Strait ice volume export.(2) Considering 9 major arctic rivers, the Arctic Ocean circulation was simulated through BOM. The result shows that: The BOM can reproduce the main Arctic Ocean circulation pattern. The"Islandization"which is commonly used in OGCMs to treat the North Pole, not only influences the ocean current near the pole, but also influences the current in the Northern Atlantic Ocean, thus the bogus island might influence global climate through thermohaline circulation in the Atlantic Ocean.
