Here, two-dimensionality may imply Feng Bin's critical attitude toward the monotony of urban life. 冯斌也许用这样的二维形式暗示他对单调的当代都市生活的批判。
The focus is on properties arising from the energy quantization and the resulting two-dimensionality of the electron system The selection of topics is based on the degree of physical interest and the level of experimental activities. 注意力集中于电子系统的能量量子化以及二维特性。专题的选择依据我们的物理兴趣和实验工作所达到的水平。
