The numerical results indicated that the mixing time decreases about linearly with increasing current intensity. The mixing time decreases first then increases with increasing current frequency and comes up to its minimum value at 30Hz. Applying the traveling magnetic field to the uptake or downtake when the exciting current intensity is 200 A at 10 Hz, the mixing time can be shortened by 9%~17%. With the operating conditions kept unchanged, shorter mixing time is available if applying the traveling magnetic field to the uptake instead of downtake, and the time can be shortened by 18%~26% if applying the magnetic field to both the uptake and downtake. Moreover, the mixing time decreases with increasing argon blowing flowrate, and the time comes down to its minimum value if the argon blowing flowrate is 1 600 NL/min. After the moment, the mixing time increases with argon blowing flowrate.

计算结果表明：混匀时间随电流强度的增大而减小，并且近似成线性关系；混匀时间随电流频率的增加先减小后增大，并且在30Hz 时达到极小值；在励磁电流强度为200A ，频率为10Hz 的条件下，在上升管或下降管施加行波磁场混匀时间可缩短9%~17%；在相同操作条件下，在上升管处施加行波磁场混匀时间小于在下降管施加行波磁场的混匀时间；同时在上升管和下降管施加行波磁场，混匀时间可缩短18%~26%；混匀时间随吹氩量的增大而减小，在吹氩量为1600NL/min 时混匀时间达到极小值，吹氩量继续增大时，混匀时间反而增大。

Firstly, This paper processes geometry filtration based on character of orbit's apogee and perigee after orbit model is analyzed and based. Secondly Space Debris is separated into two kinds, coplanar and not coplanar according as location interrelation of target and debris. In Dynamic filtration's processing, considering prediction time limit and orbit perturbation, secular effects which have increaser effect is considered so that some need catching danger time point is appeased, some law about time when target and debris pass intersectant line each other is inferred, when debris and object are in different plane and some similar law also is inferred otherwise. The time list is arithmetical progression. These laws can improve calculation efficiency remarkably; Lastly orbit predict is a course approaching least distance. Danger time point in the last step become beginning time point from which debris and object's position and velocity are calculated by SXP4 Model which is an analytic model.By result, determine that relative movement trend is closer or apart, farther calculate the interval apart from time when predictive least relative distance occurs. Least relative distance and time when least distance occurs is calculated finally. It is a fast approach course adopting varied interval.

本文在分析、建立轨道摄动计算模型的基础上，首先采用基于轨道远、近地点特征对大量编目在册的空间碎片进行初步几何静态筛选，然后根据碎片与目标轨道面的相对位置特点把碎片分为异面与准共面两种情况以进行动态筛选，在筛选过程中考虑到预报时限长度和轨道摄动影响，引入了轨道摄动中具有积累效应的长期项以满足危险时间点的捕捉要求，利用了长期项摄动变化线性的特点导出了碎片与目标异面情况下各自过交线的时间序列成准等差数列的规律性和准共面情况下类似的规律性，从而显著地提高了前期轨道筛选的计算效率；最后对剩余危险碎片和目标飞行器利用SXP4轨道预报模型在前期轨道筛选的基础上以各个危险探测时间点为预报的时间起点，并根据预报计算结果，分析目标和碎片在该时间点的运动趋势是相互远离还是相互接近，推出预计最小相对距离发生时刻相对此刻的时间长度，得到其随时间变化的局部最小相对距离以及危险距离发生的时刻和相对速度，这是一个采用变时间步长、快速逼近最小相对距离的过程。

Since the above six are self-sufficient man likes to do the job, and the pursuit of self-worth, feel self-care, personal space, respect for another's privacy, pay attention to personal style and taste, do not follow the crowd, there is awareness of the law of "80 After "will consciously dislike these acts: for example, talk to others for no reason," 80 after the "more agreeable to the West are more concerned about the self-opinion, very few non-Road, concerned about others; such as, enjoy preaching others," 80后" from an early age from schools, parents, etc. too much preaching, preaching and therefore acts very much, resulting in antagonistic, their attention; For instance, to belittle the advantages of others,"80 after" consider embodies self-worth is not to derogate others premise, the more The more derogatory of others to explain their value enough, are their attractions; For instance, smoking in the office,"after 80" would be a focus on self and respect for others the organic integration of generation, because these two are not always contradictory, if that "after 80" only know that take care of their own convenience, on the wrong; such as, the mentality of not enough sunlight,"80后" feel self-care, therefore, delighted to do anything on an individual basis or as a premise, we think that good , but their psychological upset, does not endorse, they will not act in accordance with the meaning of the U.S., the ultimate manifestation of personal values on the individual feel, are their characteristics; For instance, loud make personal phone calls,"80, after" personal space, respect for others Privacy, therefore, in a public office area will be less and less to see the "80 after" unscrupulous people talking about the workplace their own affairs, the concept of privacy, especially popular in this generation will be reflected in the workplace in the past.

因为，上述6条都是不够自我的职场中人喜欢做的，而追求自我价值、在乎自我感受、重视个人空间、尊重他人隐私、讲究个人风格与品味、不随波逐流、有法律意识的"80后"会自觉地不喜欢这些行为：比如，无端议论他人，"80后"比较认同西方人较为关注自我的观点，很少道人是非，关注别人的事；比如，喜欢说教别人，"80后"从小受到来自学校、家长等的太多说教，因此对说教行为很反感，从而产生逆反，自己注意；比如，贬低别人优势，"80后"认为体现自我价值不是以贬损别人为前提的，越贬损别人越说明自己的价值不够，是他们的过人之处；比如，在办公区吸烟，"80后"将是注重自我和尊重别人有机结合的一代，因为这两者始终不矛盾，如果认为"80后"只知道照顾自己的方便，就大错特错了；比如，心态不够阳光，"80后"在乎自我感受，因此，任何事情是以个人高兴与否作为前提的，大家觉得好，但自己心理不高兴、不认可，便不会根据大家的意思行事，个人价值最终体现在个人感受上，是他们的特点；比如，大声打私人电话，"80后"重视个人空间、尊重他人隐私，因此，在公共办公区将越来越少地看到"80后"职场人肆无忌惮地谈论自己的事情，隐私的概念在这一代特别流行，将会体现到职场中来。

The pneumonia ' this serious attack, causes her to think oneself likes a piece of delicate leaf, can blow as necessary by the cold wind she only is pessimistically was waiting for outside the window on the Changchun cane last the piece of leaf falls thin thin aftertaste, I detected she does this only is wasting own time although the time is an indifferent thing, it cannot pause the moment for someone but it is very fair, all has the certain time for each people, some people are unable reasonably to control own time, only is ignorantly muddles along, Only then causes the time quietly to sneak off, why finally falls empty throws the person which the time passage a deep sigh wastes the time often only to have when at that time only then to understand ' treasures the time the importance ' _ American scientist Franklin to say: You deeply love the life?

肺炎'这个沉重的打击，使她觉得自己像一片纤弱的叶子，随时会被寒风吹走。她只是悲观地等待着窗外长春藤上最后一片叶子的落下。细细地回味一下，我发觉她这样做只是在浪费自己的时间而已。虽然时间是个冷漠的东西，它不会为了某一个人而停留片刻。但它还是很公平，给每一个人都拥有一定的时间，有些人无法合理地支配自己的时间，只是浑浑噩噩地得过且过，才使得时间悄悄地溜走，最后落得虚掷年华的一声长叹。浪费时间的人为什么往往只有等到那时才懂得'珍惜时间的重要性'呢！

Response time is defined as the same point in the panel above to change from black and white plus the time required for change from white to black response time LCD there is a matter of time because the LCD is based on the rotation angle of liquid crystal molecules to control the light light and dark gray rotation of liquid crystal molecules will take time. the general aim is to monitor the use of word processing and web browser is under normal circumstances will continue to monitor display screen with a long period of time, then switch to a different picture of such a In fact, the use of fast response time more than slow the user is not affected but if you want to use animation or video monitor view will continue to change because the screen did not stop this time the response time will affect the picture quality.

坏点所谓坏点，是指液晶显示器上无法控制的恒亮或恒暗的点，坏点的造成是液晶面板生产时因各种因素造成的瑕疵，可能是particle落在面板里面，可能是静电伤害破坏面板，可能是制程控制不良等等等，坏点分为两种：亮点与暗点，亮点就是在任何画面下恒亮的点，切换到黑色画面就可以发现，暗点就是在任何画面下恒暗的点，切换到白色画面就可以发现，一般来说，亮点会比暗点更令人无法接受，所以很多monitor厂商会保证无亮点，但好像比较少保证无暗点的，有些面板厂商会在出货前把亮点修成暗点。
