For each reference that you find, you must trace into the object that it points to and then follow all the references in that object, tracing into the objects they point to, etc., until you've moved through the entire web that originated with the reference on the stack or in static storage.

每当你找到一个引用就跟踪下去，找到对应对象，标记它，列出其包含的所有引用并一个个再跟踪下去（－J－有点像数据结构里面的图遍历）。直到你遍历了整个栈或静态区域所引出的图。

Finally, a sequential of central points can be traced out efficiently without any iteration and a parametric curve can be reconstructed by interpolating the central points.

An algorithm about picking element is presented in this paper: First,getting certain amounts of boundary points by contour tracing from a point near an element and calculating primal parameters; Then, picking the element completely by element tracing guided by these initial parameters, jumping over broken points and intersecting points; At last,deleting the picked element from the raster image and renewing other elements' information intersecting with the picked element.

本文提出一种图元拾取算法：首先从图元附近一点开始，经轮廓跟踪、参数拟合得到图元的初始参数；然后在初始参数引导下，对图元定向跟踪，跳过断点和交点，最大限度的拾取整个图元；最后在光栅图像上删除该图元，并恢复与之相交的其它图元的交点信息。

个人翻译：垃圾回收过程会对所有指向活动对象的指针进行跟踪，并由此来确定所有能够被索引的对象，以及对在跟踪记录中不存在的堆内存进行调整以便再利用。

Based on the review of progress in parametric uncertainty nonlinear system control theory, it is noticed that design methods based on feedback linearization are the main parts and the author proposes a robust controller design method for a nonlinear parametrization uncertain system satisfying feedback linearization and triangularity conditions,and a robust output tracking controller for a nonlinear parametrization uncertain system based on the identification of uncertain parameters.

Based on the strong relationship about frames near by, the Author brought forward an particle filter algorithm importing weighted sampling about pre-frame in object tracking. The algorithm resolves the trickiness in traditional SIR algorithm which depends on statcmodcl acutely by importing proposal distribution. The algorithm can track object which movement is irregular.
