Firstly, we adopt the same parametersthat well fit the Milky Way disk to the M31 disk evolution. We found thatthe obtained gas surface density and star formation rate profiles do notfit the M31's observation. This demonstrates that the star formation history inthe M31 disk may totally different from that in the Milky Way disk.

首先，我们将银河系的化学演化模型应用于M31上，发现银河系的恒星形成速率与气体面密度的关系并不符合M31的观测特征，这说明两者拥有不同的恒星形成历史。

Into a disk, I observed careful about the rotation of the disk and head movements to the piece, under the advance and retreat into the situation, such as motor and found that the rotation of the disk normal, the motor did not act in big problem, but components in the empty head or disk, the sliding pole in the slide is very difficult to switch off the power supply, pushing gently with his hands under the head of several components to slide in the poles, there is clear sense of the hysteresis.

放进一张碟片，笔者仔细的观察了一下碟片的旋转及光头给件的动作，下进等电机的进退情况，发现碟片的旋转基本正常，电机的进退也没太大问题，反而光头组件在空载或加碟片的情况下，在滑动杆上滑动十分吃力，关掉电源，用手轻轻推了几下光头组件使其在杆上滑动，有很明显的迟滞感。

All resources and operation in system disk will not be saved acquiescently after shutting down or restarting operating system. Conversely, default security strategy of user disk is saving operation in this disk.

RESULTS:In vertebral pulp extirpation group, the stress was proved to be the highest at superior edge, posterior middle part, lower edge and anterior middle part of small joints under anteflexion, backward extension, compression, lateroflexion and revolving states, moreover, small joint stress in artificial lumbar intervertebral disk was higher than that in normal intervertebral disk, but obviously lower than that in vertebral pulp extirpation group;however, the small joint of the middle part of artificial lumbar intervertebral disk bore the highest stress under revolving states.

Because any reports on the active control of rotating disk haven't be seen in China up to now, and this experiment research is important, so the complete set of active control system of rotating disk are built independently. The push-pull type electromagnet is applied to control the vibration of the circular disk. The power amplifier circuit that can respond to wide scope in frequency from DC to AC is designed by improving the existing circuit. The sensor signal is first low-pass filtered, then the proportional control plus the differential control circuit easy used in practice are applied to finish the more effective control. The electromagnetism shield is used as possible to decrease the signal disturbance from the electromagnet to eddy sensor.
