Stability of implants was measured by rfa regularly.results there was no significant difference between both groups about stability at all periods and histomorphometry, but isq, bic and ba of experimental group were higher than control group, and isq recovered more quickly in experimental group after loaded.conclusion dual threads design contributes to assure the initial and secondary stability of implants, which is particularly important in poor density bone.

结果 两组种植体在各时期的稳定度差异均无显著性，但在每一时期实验组种植体的稳定度均较对照组高，实验组种植体在负重后稳定度恢复较快，负重3个月后实验组的骨-种植体接触率和种植体周围骨面积均较对照组稍高，但两者差异无显著性。结论双梯形螺纹种植体有利于保证种植体的初期和后期稳定性，应用于低密度骨质优越性会更加明显。

Based on the composite bounded reservoir model with two porous media, the Laplace solution of dimensionless pressure distribution under inner boundary condition (considering the wellbore storage and the skin effect) has been studied, and through analyzing the structures and interrelations of Laplace solution, the correlations with usual composite, two porous media and homogeneous reservoir pressure distribution have been found.

To compare with traditional EVT system, reserved some advantages, such as two rotors can run at different speed, and so on. The innovations of BL-DMPM included:① No brush and slide rings were needed, so simpled the structure of motor, and improved the reliability.② The rated speed of two rotors can be different according to selection of pole numbers, so the proposed motor was more appropriate than the traditional one when it was used in hybrid electrical vehicle, where large torque at low speed was needed.

它保留了传统双机械端口电机的主要优点，如两个机械端口可运行在不同转速和可无极连续变速等，而取消了传统双机械端口电机中的电刷和滑环，简化了电机结构，提高了可靠性，可以设计成使两个机械转子的额定转速相差很大，从而更适用于需要低速大力矩的混合动力汽车等场合。
