The "abstract framework of divided time" became "the point of reference for both action and thought."

这种"抽象的可分割的时间框架"成为了人们"行动和思维的参照点"。

An extra force is produced using the piecewise-constant MS model during the segmenting. In each time step, the additional force is added to reinitialize the level set function, advance the speed of the curve evolution. Otherwise, a nonlinear function Ψ is introduced to instead of u+ and u-for edge preserving in MS model.

该方法在分割过程中利用分段常数MS模型产生一种驱动力，在每个时间间隔加入这种驱动力来推动水平集函数的进化，提高曲线演化速度；另外，通过在MS模型中引入一个非线性函数Ψ代替u+和u-实现保边。

And is not time even as love is,undivided and spaceless?

时间不就和爱一样，是无法分割也是无穷尽的吗？

It will expose the design problem of maintainability of civil airplane to the early stage of design. This paper discusses the composing of the virtual maintenance environment, builds non-immersion virtual maintenance environment of undercarriage, and establishes a part library management system. The characteristic of maintainability models and maintainability analysis based on virtual technique is researched to give the maintainability frame model of civil airplane virtual maintainability analysis. All levels of maintenance time model and maintenance man-hour model are established. Analog-Huffman code is proposed to optimize space partition method in traditional collision detection arithmetic."Maintenance therblig"is brought into the broken down of maintenance tasks, and the new maintenance tasks broken down method is proposed. The demands of human measure, position, and equipment layout in human engineering are discussed, and the verification methods of human measure, position and equipment layout in virtual maintenance are given. Basic principle and verification procedure of maintainability virtual verification is developed primarily, and the reachablity, the visibility, and posture-comfortability are verified.

Get ride of the background and unrecoverable region can not only reduce the time of preprocessing, but also improve the reliability of feature extraction considerably.

分割出指纹的有效区域，可以缩短指纹图像预处理的时间，提高特征提取的准确率。

At the same time, to reserve the correlation between short snippets, the adjoined sequences between them are considered, instead of breaking these longer sequences simply. This method can reduce the requirement of time and space, and reserve the global information.

为了保留短片断之间的相关性，并不是简单地分割这些长序列，而是同时考虑了短片断之间分界点两侧的序列，这样既可以降低算法对空间和时间的需求，又尽可能地保留了全局信息。
