石灰石-石膏法脱硫装置中吸收塔的腐蚀在整个装置中是最严重的，而吸收塔是整个装置中最重要的设备，直接决定脱硫效率的高低，从而对吸收塔的防腐衬里材料的选择、设计和施工尤为重要。

Refer to the domestic and foreign literature material, to establish traumatic joint stiffness model with New Zealand big white rabbit;caused the right knee joints of the big white rabbits closed trauma with the appropriate mothod,then fixed the behind-right knee joints 4 weeks with the gypsum and the bandage;after 4 weeks, removed fixture,examined the animal blood rheology,the joint range,the skin temperature, the arthrocele extent and so on ,to authenticate whether modeling succeeded or not.

参考国内外文献资料，用新西兰大白兔建立创伤性关节僵直模型；用适当的方法造成大白兔右后膝关节闭合性损伤，用石膏绷带、绷带固定4周，4周后拆除固定。期间观察皮肤温度、关节肿胀度、关节活动度，检测动物血液流变学等指标，以验证模型建立是否成功。

Taking Newzealand rabbits as our study objects, we have build some osteoarthritis animal models by fixing the rabbits′ left posterior knee joint in stretching state plaster for 8 weeks. According to different ways of movement, the influence of movement upon the morphology of decayed arthrochondritis under light microscopy and scanning electron microscopy were observed.

以新西兰白兔为研究对象，用伸膝位石膏固定8周的方法建立骨关节炎动物模型，按运动方式不同，随机分成5组，从光镜、扫描电镜两方面观察运动对退变关节软骨的组织形态学影响。

S white rabbits as our study ob jects, we built some OA animal mode by fixing the rabbits left posterior knee joint in st retching state into plaster casts for 8 weeks. After imposing active movement, p assive movement, active-passive movement and free movement on the knee joint, we have made an X-ray examination of the knee joint, and tried to observe the chan g e in the movement degree of the joint and in the biomechanics features, we also observed the influence of movement upon the morphology of arthrochondritis.

以新西兰白兔为研究对象，采用左后膝伸直位管型石膏固定8周的方法建立OA 动物模型，通过施加主动活动、被动活动、主动加被动活动，自由活动等运动处理因素，观察X线检查、关节活动度、生物力学特性和软骨组织的形态学改变。
