The earliest change of ERG in birdshot chorioretinopathy was the prolongation of cone ERG implicit time. Followed by the decrease of dark-adapted b wave amplitude. The b wave amplitude of cone ERG decreased later. The duration of the disease correlates with the amplitude of b wave in the same patient. The a wave was the last affected and the decrease of the a wave amplitude was disproportionate compared to that of b wave, revealing a typical negative type ERG.

结果发现最早的变化为锥细胞ERG潜伏期的延长；接着是暗适应b波振幅下降，锥细胞b波下降较晚，同一患者病程的长短和ERG b波振幅下降幅度一致；a波振幅下降晚于b波，且下降不成比例，出现负相ERG，可作为诊断此疾病的特征性ERG。

The possible mechanism is that, when there is an asymmetry of RhoA activity in the growth cone, the filopodia at the lower RhoA activity side will extend faster then the other side because of lower inhibition or retraction, and hence the growth cone will turn towards this side.

可能的机制是，当生长锥内一侧的 RhoA 活性较另一侧高时，丝状伪足在 RhoA 活性低的一侧受到的抑制较弱，延伸更快，因此生长锥朝向该侧转向。

One simplified hypothesis is that, when the growth cone detected the directional signal, actin will polymerize asymmetrically in the growth cone, so that the filopodia and lamelipodia will extend preferentially to one side, microtubule will further follow and stabilize this growing direction.

一种假说认为，当轴突生长锥探测到方向性的信号时，生长锥内的 actin成分发生不对称聚合，filopodia及lamelipodia向一侧优先延伸，进而轴突内微管也朝同侧延伸，使生长方向进一步稳定下来。

Lock angle in the design and the cone has made the appropriate choice, cone friction that makes the engagement ring gear tooth sets and the rapid synchronization, and will produce a Lock role and to prevent the gear before engaging in sync.

锁止角与锥面在设计时已作了适当选择，锥面摩擦使得待啮合的齿套与齿圈迅速同步，同时又会产生一种锁止作用，防止齿轮在同步前进行啮合。

Joint sets, to be simultaneously lock engagement ring and the ring gear on the gear are Chamfer, lock ring simultaneously with the question of the cone gear engagement ring gear, cone contact with friction.

When the lock ring simultaneously with the question cone gear engagement ring gear, cone after contact friction moment in the role of the rapid speed of gear to reduce to synchronize with the speed equivalent to lock ring, the two synchronous rotation, relative to gear Central lock synchronization speed is zero, thus inertia torque also disappeared, then in force under the impetus of engagement sets unhindered and synchronization lock Gear engagement ring, and further engagement with the question of gear engagement ring gear and completed Shift process The topics mainly through the Pro / E synchronization software for the car to three-dimensional modeling structural design, and through the parameters of the design process to achieve its structure, and on this basis, the use of ANSYS FEM software structure of the typical synchronization And a finite element analysis, through structural analysis of its structural design is reasonable to assess and make recommendations to improve the design

当同步锁环内锥面与待接合齿轮齿圈外锥面接触后，在摩擦力矩的作用下齿轮转速迅速降低到与同步锁环转速相等，两者同步旋转，齿轮相对于同步锁环的转速为零，因而惯性力矩也同时消失，这时在作用力的推动下，接合套不受阻碍地与同步锁环齿圈接合，并进一步与待接合齿轮的齿圈接合而完成换档过程本课题主要是通过Pro/E软件对汽车同步器进行三维造型结构设计，并通过参数化实现其结构设计程序化，在此基础上，利用ANSYS有限元软件对典型同步器结构进行有限元计算与分析，通过结构分析对其结构设计的合理性作出评价并提出改进设计建议
