On the condition that the primary optical axis of the seeker was fixed to the missile top, the expressions of imaging compensation were educed by analyzing imaging laws of the moving target relative to the rotating seeker. An estimation algorithm based on the coupling image was used to realize real-time tracking for the angle velocity. After discussing some relative problems such as glint and fabric noises, a filter based on wavelet decomposition and weighted smoothness was utilized.

通过分析目标相对于旋转导引头的成像规律，推导出图像反旋补偿的公式，研究了基于图像的角速度估计算法，实现了对自旋角速度的实时跟踪；同时对成像过程中产生的闪烁噪声、抖动噪声等进行了分析，并在角速度跟踪时，采用基于小波滤波与加权平滑的方法进行去噪处理。

After some passionate Expressions of the old Acquaintance, I enquir'd, you may be sure, after my Plantation and my Partner: The old Man told me he had not been in the Brasils for about nine Years; but that he could assure me, that when he came away, my Partner was living, but the Trustees, who I had join'd with him to take Cognizance of my Part, were both dead; that however, he believ'd that I would have a very good Account of the Improvement of the Plantation; for that upon the general Belief of my being cast away, and drown'd, my Trustees had given in the Account of the Produce of my Part of the Plantation, to the Procurator Fiscal, who had appropriated it, in Case I never came to claim it; one Third to the King, and two Thirds to the Monastery of St.

老友重逢，交谈之际，言词热切。不用说，我接着就询问了我的种植园和合股人的情况。老人家告诉我，他已有九年没有去巴西了。但他可以向我保证，当他离开那里的时候，我的合股人还在人世。我曾委托他和另外两位代理人照管我的产业。尽管那两位代理人已经过世，但他相信，关于我那种植园的收益，我还是不难收到一份种植园这几十年来发展的详细报告。

Objective To evaluate the expressions of COX-2 and PCNA in bladder transitional cell carcinoma and its prognostic significance.

目的 探讨COX-2和PCNA在膀胱移行细胞癌中的表达及临床意义。

None. Some countries, such as France and Spain, have academies that claim the right to regulate their national languages, and to repel invasive terms, usually from English. Neither England nor the United States attempts such an exercise in futility. English is a mongrel language that keeps its vitality by absorbing new words, uses and expressions. It promiscuously plunders other languages and delights in neologisms. It is the language of free traders and inventive entrepreneurs such as the staff of the Global Language Monitor.

绝不 的某些国家比如法国和西班牙有学术机构宣称有权管制他们国家的语言并抵制那些外来术语主要外来的英语术语无论英国还美国都不会做这种徒劳无益的事情英语一种杂交语言一直靠吸收新词、新用法和新含义来保持其生命力它杂乱地掠夺其它语言并以增加新词为乐它"全球语言监测公司"的职员之类的自由贸易者和有才能的企业家的语言
