Based on Pseudo-linearization and least square methods, the bearings-only target motion problem was studied under the conditions that the target takes uniform rectilinear motion in 2-dimensional space, the single observer takes uniform rectilinear motion first, and then takes rectilinear motion with constant acceleration. The necessary and sufficient observable conditions, some unobservable conditions are gained.

Embarked on the definition and research object of CEDZs, this article first made some introduction of the developing phases of the world's developing areas; then it dealt with the theoretical secundum, objective and strategic meaning of the developments of CEDZs. After that, it made some concise descriptions of the historical developments of CEDZs, focusing on analyzing and researching of the CEDZs'past experience and theories. It holds that CEDZs helps to push ahead with China's urbanization, industrialization, high-technology development, economic development, modernization, reform and open-gate policy process. At the same time, there are also some drawbacks existing.

本文从开发区的涵义和研究对象着手，首先介绍了世界开发区的演进与发展；然后就中国开发区建设的理论依据、目的及战略意义作了论述；随后再对中国开发区的历史发展作了简要描述后，重点对中国开发区的经验与理论作了分析和探索，认为开发区推动了我国城市化进程、工业化进程、高新技术发展进程、经济发展和现代化进程以及改革开放进程，同时开发区在发展过程中也存在一系列的误区。

There were inflammatory cells infiltrating in the myocardium sparely and no calcification in the pericardium in IVIG and IVIG+VitC groups. The size of spleens enlarged especially in IVIG and IVIG+VitC groups.

Lyricism to lyric means of literature are diverse: one is willing to speak one's mind's made, the hero is the author's own, works directly express the hero's thoughts and feelings, showing the hero's personality characteristics; One is the care of things for Yan Zhi, the work is not that the author's own hero, but the author's thoughts and feelings of the sustenance of the objects, including figures, there are things, as well as by the negative objects; one is made by the King of the lyric, that is landscape features poetry, on the surface, written by the author saw and heard was not the hero tone of voice to express thoughts and feelings, but in fact the author is described by the mountain scenery to send Italian lyric, its hero is actually author.

抒情文学借以抒情的手段是多种多样的：一种是直抒胸臆之作，主人公就是作者自己，作品直接抒发主人公的思想感情，显示主人公的性格特点；一种是托物言志之作，作品的主人公并不就是作者自己，而是作者的思想感情所寄托的对象，其中有人物、有事物，还有作者否定的对象；一种是借景抒情之作，即山水景物诗文，表面上看，所写作者所见所闻并不是作者以主人公口吻来抒发的思想感情，但实际上作者是借山林景色的描写来寄意抒情，其主人公实际上就是作者。
