碎片的

As Simon watched, delighted, the gray catling found a loose piece of flint and batted it skittering across the tiles, following to hook it with an agile paw and begin the game anew.

Simon欣喜地看着它，这只灰色的小猫发现了一块脱落的瓦的碎片，拍了一下，把碎片打飞到石瓦的远处，小猫跟过去，一只敏捷的爪子钩住碎片，再重新把它打出去。

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。

According to the experiment results of degradation in field, degradation mechanism of the biodegradable mulch film can include four stages: the first, the material surface appeared deficiency while the surface area and interstice increased of material in the action of natural environment and microorganism; the second, along with the surface area and interstice of material increased and the gap strengthened, the chemical chain of the high polymer's principal chain broke as a result of the hydrolysis or the enzymatic effect in the action of hydration, causing the molecular weight and mechanics function descended; the third, the molecular of high polymer split the low polymer after its physical mechanical function descended, the material decomposed the fragments, the mass defect intensified; the fourth, the low polymer of fragments form in the natural environment, the microorganism, the biological enzyme became the smaller fragments, thus absorbed by the phagocytes, or further turn into CO2 and H2O due to hydrolysis.

根据田间降解试验结果推测，生物全降解地膜的降解机理可能包括四个阶段：第一，在自然环境、微生物作用下，材料表面出现缺陷，同时表面积增大、空隙增多；第二，随着材料表面积的增大、空隙的增多，吸水性增强，在自水合作用下，高聚物主链由于水解或酶解而使化学链断裂，导致分子量和力学性能下降；第三，在其物理机械性能下降后，高聚物分子链断裂为低聚物分子，材料裂解为碎片状，质量损失加剧；第四，碎片状低聚物在自然环境、微生物、生物酶作用下进一步水解变成尺寸更小的碎片，从而被吞噬细胞吸收，或进一步水解，生成CO2和H2O。

Upon my going into the church, I entertained myself with the digging of a grave; and saw in every shovelful of it that was thrown up, the fragment of a bone or skull intermixt with a kind of fresh mouldering earth, that some time or other had a place in the composition of a human body.

我走进教堂，正好赶上有人挖墓。扔出的每一锨腐土中，都混杂着骨头或头颅的碎片。曾几何时，这些碎片还是人身体的一部份呢！看到这个情景，我暗自思忖，在这座古老教堂甬道下面混埋着何等众多的人呀；无论男人还是女人，朋友还是敌人，牧师还是士兵，修士还是受俸者，全都化碎片，混成一堆。美丽、强壮、年轻的人和年老、体衰、畸形的人都毫无区别地融入同一片泥土。

These data were used to infer the molecular formula and the elemental compositions of all the fragmental ions through software interpretation and, by further applying fragmentation regularities of mass spectrometry, the majority of ions were fully assigned. A base peak at m/z 402 in the mass spectrum was found as the molecular ion. The fragments were created mainly from the fragmentations of the tetrahydrofuran rings and the hydroxyl group. The most fragment products contain the dimethoxy phenyl group.
