This said, he sat; and expectation held His look suspence, awaiting who appeer'd To second, or oppose, or undertake The perilous attempt; but all sat mute, [ 420 ] Pondering the danger with deep thoughts; and each In others count'nance read his own dismay Astonisht: none among the choice and prime Of those Heav'n-warring Champions could be found So hardie as to proffer or accept [ 425 ] Alone the dreadful voyage; till at last Satan, whom now transcendent glory rais'd Above his fellows, with Monarchal pride Conscious of highest worth, unmov'd thus spake.

V1：一席话说完，他坐下，眼光里显露期待的神情，等待众人的赞成或反对，或起而表示自己甘冒风险一试。可是大家都默坐，相视无言，思虑那危险而面面相觑，各从别人的脸上照出自己的心惊胆战。就是在天战中最勇敢的精英，也没有一个自告奋勇承担起这个可怕的远征。直到最后，撒旦，那时他的荣光超群，自恃力量最大，俨有寡君的骄矜，神态自若地开口说道： V2：这样说后，他坐下，眼光里显露期待的神情，等待谁来赞成，或反对，或起而表示自己甘冒风险一试。可是大家都默坐，噤若寒蝉，沉思那危险而面面相觑，各从别人的脸上照出自己的心惊胆战。就是在天战中最勇敢的精英，也没有一个自告奋勇敢于承担这个可怕的远征。

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。

A oil warehouse was served under the backgroud of engneering application in this paper. Based on analyse and distinguish of oilcan fire, hazardous factors in explosion and accidental characteristics, consequently, inherent hazard scale of the oilcan section was educed by using DOW's fire explosive index method. In that way those errors between safety precaution and present criterion were also definited by analysising and calculating the effect of safty compensating coefficient in deducing hazardous scale of oilcan fire.

Conclusion1 Critically ill patients with indwelling catheters were of the high positive rate of microorganisms,and microorganism spectrum was of special properties;BF formed mainly inside the catheter,the occurrence rate of BF inside the catheter was high and the formation time was short;Changes on catheters and the result of microorganisms was positively correlated with the BF formation.2 Indwelling catheter time was the independent risk factors for the BF formatiom, while age、APACHEⅡscore、sex、urine sugar and the types of antibiotic usage were the potential risk factors for the BF formation;Nurses should perfect the catheter measures for critical ill patients,emphasis on the assessment of risk factors of BF formation,and implement special care in high-risk patients.3 In the early stage of BF formation,irrigation could play the role of eradicative BF effectively;While later,it couldn't,but it can delay the speed of BF formation and maturation;In the choice of washing methods,injection type washing method is superior to infusion.

结论1重危患者留置尿管微生物培养阳性率高，且微生物菌谱具有特殊性；重危患者尿管表面BF主要在尿管内壁形成；内壁BF的发生率高，形成时间短；肉眼观察尿管表面改变情况以及微生物鉴定结果与BF形成呈正相关。2尿管留置时间是重危患者留置尿管表面BF形成的独立危险因素；年龄、APAcHEⅡ评分、性别、尿糖定性以及抗生素使用种类是其可能的危险因素；护理过程中应完善重危患者尿管护理措施，注重对BF危险因素的评估，并对高危患者实施重点护理。3 BF形成早期，冲洗能发挥较好的清除作用；BF形成后期，冲洗无法彻底清除尿管表面BF，但冲洗能延缓BF形成与成熟的速度；在冲洗方式的选择上，注洗式冲洗法对尿管BF的清除效果优于输注式冲洗法。
