At first glance the task of joining that many shreds looks impossible, even when each shred has been scanned so that the matching can be done by machine.

乍一看，拼接这么多碎片的任务根本不可能，就算每片碎片都被扫描，可以用机器来做匹配处理。

Microhistological fecal analysis is an important technique for investigating herbivore diets.The conventional mounting technique uses Hoyer's mounting medium to seal the plant fragment to the slide.

粪便显微组织分析法是研究食草动物食性的主要方法，其常规装片技术需要使用Hoyer's装片介质对植物碎片进行封片，而Hoyer's封片液的粘性易导致植物碎片在装片过程中发生卷曲和重叠，影响植物碎片的识别效果。

Based on probability theory, a method for describing and calculating the collision probability between rendezvous and docking vehicle and debris is presented, and the method involves quantitatively analyzing the collision probability using quasi maximum instantaneous collision probability and total collision probability. The method calculating the indexes is developed, and the input required to perform a calculation includes the respective state vectors, position error covariance matrices and physical sizes of objects involved.(3) Two methods to analyze relative trajectory safety between chaser and target are developed, which are 3-sigma ellipsoid based methodology and collision probability based methodology.

1分析了交会对接各阶段面临的主要轨迹安全威胁，阐述了被动和主动安全策略、目标器的交会对接控制区域等保证交会安全的措施；(2)基于概率思想发展了线性和非线性运动情况下飞行器与空间碎片的碰撞判断方法，提出采用总碰撞概率和拟最大瞬时碰撞概率来综合描述飞行器与空间碎片的碰撞危险程度，推导了通过飞行器和空间碎片各自的状态矢量、位置误差协方差矩阵以及形状尺寸来计算碰撞概率的公式；(3)提出了两种分析追踪器和目标器之间相对轨迹安全的新方法：基于3σ椭球的轨迹安全分析方法和基于碰撞概率的轨迹安全分析方法。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
