快速成形技术中轮廓环的分组算法及其应用

以平面内轮廓环的存在规则和相互关系为出发点，提出了一种简单实用的轮廓环的分组算法，通过本方法对平面的轮廓环进行分组，能够把一个平面分解成一系列简单的单连通区域，分组后的轮廓环不仅能够在进行其他运算时减少重复计算，而且可以在分区填充扫描线时减少分区数，从而减少实际扫描时的空跳．

Kinetics of Chlorine Decay in Water Distribution Systems

A combined first and second-order model, which includes bulk decay and wall decay, was developed to describe chlorine decay in water distribution systems. In the model the bulk decay has complex relationships with total organic carbon (TOC), the initial chlorine concentration and the temperature. Except for the initial stages they can be simplified into a linear increase with TOC, a linear decrease with initial chlorine concentration and an exponential relationship with the temperature. The model also explains why chlorine decays rapidly in the initial stages. The parameters of model are determined by deriving the best fitness with experimental data. And the accuracy of model has been verified by using the experimental data and the monitoring data in a distribution system.

土体注浆后的性能分析

应用Mohr-Coulomb屈服准则,推导了注浆后岩土体的屈服函数.根据位于205国道上某土质边坡的实际情况,利用现场实测数据和实验数据,分别对注浆前后坡体的破坏状态、不同位置位移的变化情况以及坡体的整体稳定性等方面进行了模拟计算.结果表明,注浆后岩土体的弹性区域显著增大,侧向位移明显减小,而岩土体的剪应力屈服区域则由集中趋于分散.
