Accordingly, the author of this pa- per studies this problem of the native design of low-carbon environmentally friendly packaging. First, the author analyzes the types of the native design of low-carbon and environmentally friendly packaging and secondly, summarizes the native design concepts of the low-car- bon and environmentally friendly packaging and finally, puts forward three innovative ways of the native design of the low-carbon and en- vironmentally friendly packing.展开更多

Examples show that to solve the green charm problem and protect environment only by people's responsibility and duty is far from enough. The most important is to attract people loving the green product from the bottom of their heart and to realize the harmonious union of the nature and human beings.展开更多

These twin-tube tunnels, which have two or three lanes in each tube, are characterized by large cross-sections. Due to the complicated topography and heterogeneous geological conditions of Taiwan, tunnel construction has encountered many difficulties. Thus, many advanced excavation methods were developed during tunnel construction. To satisfy the concurrent requirements of safety, economy and efficiency, new construction methods and techniques should be developed or introduced. Moreover, environmental protection and ecological conservation must be paid increasing attention to the goal of substantial development.展开更多
