In order to predict the mechanical property and strength of the plain woven fabric composite, a finite element model of the Representative Volume Element with a convexo-convex structure was established based on plain woven fabric laminates in the distribution of micro yarn.

为更准确预测平纹织物复合材料的强度，基于平纹织物层合板内纱线的细观分布，建立具有双凸结构的特征体积单元RVE有限元模型。

The characteristic of the coplanar waveguidein multi-layer substrates for microwave circuits has been researched and experimented in this paper.

本文对多层 LTCC 微波电路基板中的共面波导的特性进行了研究和试验。

A four\|node piezoelectric composite laminated plated element was implemented for dynamic analysis of adaptive structure. The damping ratios of truncated models were considered as the control objects, so that each of the structural modal oscillation could decay rapidly. Hence, the structural oscillation was effectively controlled.

利用四节点压电复合材料层合板单元进行自适应结构的有限元动力分析；采用模态控制方法，将结构的各阶模态的阻尼比作为控制目标，并以此计算出各压电片的控制电压，达到控制结构振动的目的。

The influence of local stiffness degression resulted from damage in the impact process is simulated by modifying the material constants of damaged layers.

另外，分类考虑了不同的损伤形式，通过修正损伤层的材料常数来模拟单层板损伤所造成的局部刚度下降对压痕过程的影响。

The process of ecological degradation in the vicinity of Shaoguan Pb/Zn smelter may be summed as: heavy metals and acidic deposits from the waste gas from smelter resulted in the vanishment of the sensitive plant species, increasing accumulation of heavy metals in soils and acidification of topsoil worsened the chemical properties and then shallow-rooted plant, mainly the herbaceous, vanished. With the demolishment of the vegetation cover, increasing water-soil erosion worsened physico-chemical properties of soil and, subsequently, some woody plants disappeared and barren land was finally appeared.

该生态系统的退化过程可以归纳为：来自于冶炼废气的重金属和酸沉降导致了敏感植物的消亡，丧失了对土壤的缓冲保护作用；重金属在土壤表层的积累，酸性物质在土壤表层的增加导致的土壤酸化以及由此引发的有机质与养分的淋溶和重金属及Al的活性增加，加剧植被的快速退化，特别是浅根植物的衰亡；地被层的破坏，导致水土流失和土壤侵蚀加深，进一步恶化表层土壤的理化性质，一些木本植物随之消失，最终形成光板地。
