Even as we mourn 29 lives lost, we also remember 29 lives lived.up at 4:30 a.m., 5:00 in the morning at the latest, they began their day, as they worked, in darkness.in coveralls and hard-toe boots, a hardhat over their heads, they would sit quietly for their hour-long journey, five miles into a mountain, the only light the lamp on their caps, or the glow from the mantrip they rode in.
尽管我们在哀悼这29条逝去的生命,我们同样也要纪念这29条曾活在世间的生命。凌晨4点半起床,最迟5点,他们就开始一天的生活,他们在黑暗中工作。穿着工作服和硬头靴,头戴安全帽,静坐着开始一小时的征程,去到五英里远的矿井,唯一的灯光是从他们头戴的安全帽上发出的,或是进入时矿山沿途的光线。

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。

The Fresnel lens in the optical receptor spotlights the headlamp beams to form their image at the 1-meter distance between the optical receptor and headlamps. CMOS camera as an image sensor, takes the photos of their images, which are captured by VG-M201, The application of some digital image processing techniques to these images, such as edge-picking up、 least-square fitting-curve algorithm, is to calculate the offset position/angle of optical axis of the high beams and the nodical offset of the unsymmetrical facular light and shade cut-off line of the low beams.

Based on moving least squares surface, the differential properties of each sample point on PSO are first evaluated. In terms of covariance analysis, the elliptical splat of sample point is then determined on its tangent plane. Finally, the splats are rendered from far to near by using elliptical weighted average filtering. According to the differential properties, moreover, the suggestive contours of PSG are attained so that non-photorealistic rendering of PSG is realized.
