When the swirl variable device is part-opened, because swirl has some effect on the second injection, second injection timing has distinctly effect on fuel consumption, and the fuel consumption change fluctuantly with twice injection timing. When the tumble variable device is adopted, second injection timing also has effect on fuel consumption, but there is only one point that the fuel consumption is lowest. When the load is bigger, the second injection point where the fuel consumption is lowest is earlier than the smaller load.

在可变涡流结构中，当阀片处于非全开状态时，由于涡流运动对二次喷油的作用，二次喷油正时对发动机的比油耗存在明显影响，发动机比油耗随喷油正时改变呈较明显的波动状；在可变滚流结构中，二次喷油正时对发动机比油耗同样存在影响，但最低油耗点只有一个，当负荷较大时，最低比油耗所对应的喷油正时要更早一些。

In the dissertation, a new stabilization method, equal-density method was adopted to prepare modified asphalts with storage stability at high temperature. In this method, a compound was prepared by premixing polymer and filler, and the compound was mixed with asphalt to prepare Polymer-Modified Asphalt by changing the ratio of polymer and filler. The asphalts with good storage stability were formed with the addition of filler, by regulating the density difference between polymer and asphalt. With identifying the effect of composition factor and the technique conditions on mechanical properties of polymer/filler compound and the molecular distribution of the polymer, identifying the effect of composition factor and the technique conditions on the properties and structure of polymer/filler modified asphalt, Styrene-Butadiene-Styrene copolymer, Low Density PolyEthylene, Styrene-Ethylene-Butadiene-Styrene block copolymer modified asphalts with good storage stability and performance were prepared. Rheological method, gel content analysis and swelling measurement were adopted to elucidate the interaction between the polymer and filler. Filler reduced the difference between the polymer and asphalt with the premixing technique, which led to the improvement of the storage stability of the modified asphalts. The thermo-oxidative aging process of base asphalt and PMA were studied and the effect of antioxidant additives on the base asphalt and PMA were analyzed.

Based on the theory of environment behavior and psychology, considering user"s behavior and psychological need, the investigation scope including 2 representative urban recreation-squares and 3 pleasances, this thesis studied different users, user"s behavior, and usage quantity at different times. The results showed that there are many problems in recreation-squares of Taiyuan city, and region location, space subarea, edge effect and participation effect are main effect factors. On this basis, some optimizing design and strategy are put forward.

本文主要以环境行为学和环境心理学为理论基础，以城市公共空间使用者的行为特点和心理需求为出发点，以太原市为研究范围，通过详细调查太原市具有代表性和典型性的2个广场、3个小游园，对其使用人群、使用者行为活动、不同时间使用者数量等方面进行研究，总结出太原市公共空间中普通存在的问题，提出区位位置、空间场地分区、边界效应、可参与性效应等是影响公共空间的主要因素，并针对发现的问题，提出了改进和优化设计的建议和对策。

In the pre-experiment stage, we analyze the colors and shapes of 135 visual illusions by Kitaoka, a Japanese scholar. The result is referenced in the formal experiment. Formal experiment includes three sub-experiments: Experiment 1 is to discuss the effect of the displacement of disjunctive center on visual illusions' movement; Experiment 2 is to discuss the effect of image layout on visual illusions' movement; Experiment 3 is to discuss the effect of color configuration on visual illusions' movement. Post-experiment stage is a repeat of formal experiment to confirm the results.
