聚合物由于复杂的结构形态导致了分子运动单元的多重性。即使结构已经确定 而所处状态不同其分子运动方式不同，将显示出不同的物理和力学性能。考察它的 分子运动时所表现的状态性质，才能建立起聚合物结构与性能之间的关系。聚合物 的温度-形变曲线（即热-机械曲线 Thermomechanic Analysis，简称 TMA）是研究聚 合物力学性质对温度依赖关系的重要方法之一

1. Summary: （全文） One of Hemingway's war and love stories, this novel takes place in Italy during World War I and is tied closely to the author's own experience as an American Ambulance Driver for the Italian Army. The story opens during a lull （暂停）in the action and the reader meets a group of men who work with the wounded during battle. In the course of waiting for action, the protagonist, Henry, meets and courts（求爱） an English nurse stationed in Italy

The constituents of concern found in wastewater are removed by physical, chemical, and biological methods. The individual methods usually are classified as physical unit operations, chemical unit processes, and biological unit processes. Treatment methods in which the application of physical forces predominate are known as physical unit operations
