The main fi ndings were i copper was strongly bound to organic layer and seemed to be the main pollutant in the ecosystem while zinc was the most mobile element and did not accumulate to any specifi c part of the ecosystem, ii the forest mosses and epiphytic lichens were the most sensitive plant species and the seedlings of the vascular plants that had survived near the smelter were absent, iii there was a highly resistant soil decomposer community near the smelter although the activity of the soil animals and microbiota was low and their community structure altered, iv many insect species also suffered from pollution although the adverse effects caused by forest pests increased with pollutant load, v the low survival rate and breeding success of hole-nesting passerines near the smelter was caused by habitat changes and the quality of food, vi the adverse effects seem to be to some extent reversible after decreased pollutant load or remediation actions.

In addition, the blank holding force that is required to avoid wrinkle and rupture during conical part deep drawing is researched. The necessity of reasonable blank holding force in pressing is expounded. From the view of mechanical analysis, the wrinkle critical condition of side-wall is derived for the first time by the stress state of side-wall, the main deformation region on blank. According to the critical condition of plastic instability for flange, side--wall, corner of punch on blank, The blank holding force in conical part deep drawing is divided into four different regions within its forming figure. The basic principle of reasonable blank holding force during stamping is summarized and provided. The mathematical model of reasonable blank holding force that avoids the wrinkle and rupture is established and verified by the finite element numerical simulation and the grid experiment method. The result shows that it is accurate and reliable.

此外，本文还研究了圆锥形件拉深成形过程中，随着拉深变形过程的进行，毛坯为避免产生起皱、破坏缺陷而对压边力的需求情况，阐明了圆锥形件拉深成形过程中压边力合理变化的必要性；由毛坯主要变形区悬空锥壁部分的受力变形情况，从力学分析的角度，首次推导得出了圆锥形零件悬空锥壁起皱失稳的临界条件；并根据主要变形区法兰、悬空锥壁及凸模圆角部分的塑性失稳临界条件，在其成形范围图中，将圆锥形件成形过程中的压边力划分为四个区域；总结并提出了圆锥形件成形过程中压边力合理变化的基本原则；建立了防止起皱、破坏缺陷产生的压边力合理变化的数学模式，并得到了有限元数值模拟及网格实验法的验证，证实了理论分析结果的正确性和可靠性。
