Phthalic acid esters are widely used in the many fields of industry. So many countries including China have come to pay attention to them and make up the codes for limiting the content in some products such as textile. By combining international codes, the thesis selects coating and textile that have close relative with people as objections. The research results are as follows:1. The thesis has established the textiles preparation method by a series of experimentations such as extraction solvent, extraction time, solid-phase extraction. The average recoveries of eleven phthalates are from 80.30% to 98.00%, and the relative standard deviations from 0.59% to 2.56%, the results show that this method is accurate and credible.2. The thesis set up the simultaneous determination of benzene, toluene, xylenes and phthalates in coatings.

Through above numerical analysis of the TiN coating/substrate system, some typical rules about the fatigue failure are found:(1) the fatigue damage of a coating/substrate system appears first on the interface, then expands along the interface and to the substrate, and finally causes the coatings broken and spalled;(2) under the cyclic loadings of tangential sliding and radial extrusion, the equivalent plastic damage on the interface is mainly generated by the shear stress and the accumulated plastic contributed by the increments of shear stress. Thus the change of the shear stress is the main factor for the contact fatigue damages of coating/substrate system;(3) the frictional coefficient, external loading and coating thickness have some influence on the carrying capacity and contact fatigue life for a coating/substrate system.

通过对TiN涂层／基体系统的数值模拟分析，得到了涂层／基体系统疲劳失效的一些典型规律：(1)、涂层基体的初始损伤首先出现在交界面处，然后沿界面并向基体中扩展，最后导致涂层断裂而发生剥落失效；(2)、在切向滑动和径向挤压循环载荷作用下，交界面处的塑性损伤主要是由剪应力τ产生，塑性累积也是由于△τ的变化引起，说明循环过程中剪应力变化是影响涂层接触疲劳破坏的主要因素；(3)、材料摩擦系数、外界载荷大小以及涂层厚度都对涂层／基体系统的承载能力以及疲劳寿命都有一定影响。
