With the different laboratory compaction method and the real pavement, the study of particle stability and density indicated that Marshall compacted specimen can not simulate the real pavement, the rolling and gyratory compacted specimen are the most similar with real pavement, vibrating compacted specimen is second similar with the real pavement.

针对不同试验室压实方法成型试件和实际路面，从集料颗粒的稳定性和密实程度两个角度的对比研究表明，马歇尔击实成型试件法无法有效模拟实际路面，表现在其粗集料颗粒主轴取向无统计规律且与实际路面不具相关性；轮碾压实和旋转压实试件具有与路面最接近的稳定性和密实程度；振动压实次之，虽然表现出具有使颗粒较好均匀分散成型的特点，但其粗集料颗粒骨架的稳定性不够理想，致使其密实程度相对不高。

As the novel design of the fusion apparatus improves the mechanical strength of fixation of STT and prevents the possible rotation and collapse of fused STT, the apparatus is a reliable internal fixation device for the limited intercarpal arthrodesis.

Loaded the simulated acetabular cup at an inclination of 35°, 40°, 45°, 50°, 55° to 6 cadaver pelves. Made the pelves tilt around the frontal axis and sagittal axis with 5° each time in a scope of ± 30°. Take standard radiograph of the pelvis accordingly.

按35°，40°，45°，50°，55°外展角分别放置于6具防腐骨盆标本髋臼窝内，使骨盆标本沿冠状轴、矢状轴在±30°的范围内按5°/次分别旋转，保持X射线投照中心点始终与标准骨盆正位片投照中心点一致。

RB Series peristaltic pump can transfer the materiel through liquid now with the pressure of peristalsis by gyred roller.

RB系列蠕动泵是通过旋转的滚柱使胶管蠕动来输送液体的。

Rotary coupon test has been used to study corrosion inhibition of PESA, it has been found that when PESA was used separately, it has some effect of preventing corrosion.

采用动态旋转挂片法研究了PESA的缓蚀性能，发现PESA单独使用时对碳钢即有较好缓蚀作用，其缓蚀作用的本质是在材质表面生成了吸附膜，具有最佳缓蚀效果的分子量范围在750－1000。

The algorithm is applied in the segmentation of Magnetic Resonance Imaging of human brain for the 3D reconstruction on dependent of different human tissue structures, in which the problem on wraps between different tissues and fuzzy edges between the different regions in medical volume data may better be settled, which can not be well done by the typical"hard"segmentation using binary logical representation.(3) An accelerated algorithm of volume rendering with X-ray perspective and Phong shading effect based on textures mapping and blending is presented for realizing 3D reconstruction of medical volume data by 2D texture mapping and blending, in which the accelerated algorithm of window transformation is utilized to computing voxels' gray scales and opacities to produce X-ray perspective images, and Phone illumination model is used to import world light sources and an unit spherical surface under the same shading environment as the actual volume rendering is employed to simulate the real reflectional light of per-voxel so that 3D reconstruction possesses illumination effect in the world. Furthermore, 3D matrix transformations of degree rotation and other operations of 3D object are studied, and a fast equivalent method of corresponding shading correction is brought forward to improve its interaction speed in volume rendering process.

该方法利用体数据的窗口变换加速算法将医学体数据转换为计算机显示值，可以得到具有X光透视效果三维图像；该方法提出的Phong明暗处理加速算法利用Phong光照模型引入外部光源，使用一单位球面体来仿真体数据的法线矢量集所产生的反射光强，以快速得到每一个体素的反射光强度，使物体的三维重建达到现实世界中人眼直接观察的逼真效果；此外，还研究了三维重建物体的三维旋转等矩阵变换，提出了一种Phong明暗修正的快速算法来保证了体绘制中三维几何变换的多视角观察的交互速度。

The main changes were the downward and backward rotation of the mandible, the retrusion of the lower incisors, the protrusion of the upper incisors.FR-Ⅲ also promotes the growth of maxilla and reaches the normal relationship of the anterior overjet and overbite.

结果：FR-Ⅲ能矫正上下颌基骨异常的矢状关系，主要变化是下颌骨向下、向后旋转，改变下颌骨生长的方向，同时使下颌切牙舌倾、上前牙唇倾，上颌骨向前生长。
