A new concept about organic-inorganic thermoelectric material was proposed. New composite material possessed the thermoelectric properties, which the organic and inorganic thermoelectric materials own. Synthesis and properties of polyaniline/skutterudite composites were investigated.

为进一步扩展热电材料领域及探索新型热电材料，本文首先提出了有机-无机复合材料的概念，并对NaFe〓P〓粉末材料与聚苯胺复合形成的聚苯胺／方钴矿复合热电材料的合成和性质进行了初步研究。

The exact position where pear scab parasite in leaves was pectin layer.The primary injections of V.nashicola to resistant,suspectible and non-host materials were similar,the increasing rate of subcuticular hyphae on suspectible material is far higher than resistant and non-host material,and dead hyphae appeared on resistant and non-host material,which indicated that resistance expressed after hyphae had invaded cuticular.

梨黑星菌在叶片中寄生的具体位置是果胶层。V.nashicola对抗性、易感和非寄主材料的初期侵染相似，当真菌侵入角质层之后，亚角质层菌丝在易感材料中的增长速率远远高于抗性和非寄主材料，并且在抗性和非寄主材料上出现死亡菌丝，这些都表明抗性是在真菌侵入角质层之后表达的。

Based on analyzing and summing up the study results on deformation and fracture mechanisms of materials and member under repeated impact load,this paper shows that material defomation is characterized by plastic deformation concentrating on impact point,multi-systemes sliping difficult to perform and strain more unhomogeneous.

本文综合归纳了材料和构件在循环冲击载荷下的变形、断裂规律及机理研究成果，指出材料的变形具有多系滑移难于进行、应变不均匀性大和塑性变形集中在冲击接触点的特点；材料断裂过程为裂纹萌生、扩展和最后断裂过程，组织及实验条件对材料断裂有较大影响。
