请帮忙翻译下面几段话,
众所周知,传统的桥式抓斗起重机需要人工来完成对抓斗的定位及抓料和卸料工作,工作人员的工作带有很大的经验性和随机性,另外起重机的抓斗在抓料-向前运行-卸料的整个工作过程中由于惯性、空气阻力等因素的干扰会使抓斗在前进方向上往复摇摆以致造成抓、卸料定位不准,小车向前运行速度不均匀等不利后果,严重阻碍了起重机工作效率的进一步提高.
本论文针对以上所说的抓斗摇摆问题提出抓斗“飞行”抛料的工作方案,通过对抓斗整个抓料、运料、卸料过程中抓斗及小车的运动状态进行理论建模、分析,进而找出合适的“飞行”抛料条件,即抛料时间、抛料位置及抛料时货料及小车的水平速度等,从而利用抓斗的摇摆来实现抓斗的“飞行”抛料控制,并通过运动学仿真软件ADAMS对上述抓料、运料、卸料过程进行简单的实体建模、施加相关约束、运动仿真及优化,来验证上述“飞行”抛料的可行性和可控性,最后将抓斗“飞行”抛料与目前抓斗起重机工作时常用的“正对”卸料进行比较,得出结论如下:
1.采用“飞行”抛料时,小车在轨道上移动的位移要比“正对”卸料时减少一段位移,该位移的大小近似等于物料在空中飞行的位移.
2.采用“飞行”抛料时,起重机完成整个抓、运、卸料动作过程的时间会比“正对”卸料时短.
因此,采用“飞行”抛料可以提高抓斗起重机的工作效率.
还有这句话:

Know to all,the traditional bridge type grasp the derrick of grab bucket needs the artificial to complete to grasp to anticipate and unload to anticipate the work towards grasping the grab bucket of position and,the staff member's work takes to have the very big experience and randoms,another derrick grasp the grab bucket is in grasp anticipate- forward circulate- unload anticipate of the whole work process because of inertial,the air resistance etc.factor of interference will make grasp the grab bucket fore enter the direction to sway up the back and forth with the result that result in grasp,unload to anticipate fixed position to prohibit,the small car circulates the speed asymmetry to wait the disadvantageous result forward,obstructing further exaltation of the derrick work efficiency seriously.
This thesis aims at the work project that the above grasps the grab bucket reel problem to put forward grasping the grab bucket " fly" to throw to anticipate,pass to grasp the grab bucket whole grasp to anticipate,carry to anticipate,unload to anticipate to grasp the grab bucket and small car in the process of sport appearance carry on the theories to set up the mold and analyze,then find out the fit" fly" to throw to anticipate the condition,then throw to anticipate time and throw to anticipate the position and throw to anticipate the goods anticipate and the level speed of the small car etc.,thus make use of the reel of grasp the grab bucket to carry out the " fly" of grasp the grab bucket to throw to anticipate the control,and through a kinetics imitate the true software ADAMS to above-mentioned grasp to anticipate,carry to anticipate,unload to anticipate the process to carry on the simple entity to set up the mold,exert the related stipulation and exercise to imitate true and excellent turn,verify the above-mentioned" fly" to throw the possibility for anticipate and can control sex,finally will grasp the grab bucket " fly" to throw to anticipate with currently grasp" positive rightness" that the grab bucket derrick work often use to unload to anticipate to carry on the comparison,get a conclusion as follows:
1.When adoption" fly" to throw to anticipate,small car at orbit up the ambulatory moves to want that the ratio" positive rightness" unloads to anticipate reduce a to move,that move of size look like to be equal to the material to fly in the sky of move.
2.When adoption" fly" to throw to anticipate,the derrick complete the whole time that grasp,carry,unloads to anticipate to act the process and will compare" positive rightness" to unload to anticipate the hour short.
Therefore,the adoption"s fly" to throw to anticipate the work efficiency that can raise to grasp the derrick of grab bucket .
The derrick grasps to unload to anticipate the action analysis and kineticses to imitate the true research
