First of all , it is seen in Zhang Wei"s long writing that continuous changes occurs with the following era contexts which is shown. First, the gradual desalinization of " earth image " on the space," earth " is not only a creation in Zhang Wei"s novel, but the main source of the poesy of its works. It declines after " September fable ", not only indicating Zhang Wei "s decay of poesy of the novel, but also reflecting the disobeyed pross of light appear contemporary China social urbanization and common customs to . Second, the change of " writing subject projection " in the spiritual meaning, Its characteristic displayed by the reduction of image of spokesman as write thought representation .and on the other side represent" person who want more that resist actively " which also shows contemporary intellectual predicament and adjustment of value. Third, in " changeable and separate characteristics in the stylistics ",It changes " epic body " of" Ancient ship "," body not mythical " to " September fable "," pour out body " of" Bai Hui "" Family "," the discipline spreads the body "of Book of other provinces"," lie body " of" Can not recall the hollyhock ". Its constant changes persuing of recreation and sports, has entered into the different book mode and narration of different class gradually too.

首先，张炜的长篇写作中可以看出一种跟随时代语境而不断发生的变化，这表现在：一是空间上的"大地意象"的渐趋淡化，"大地"不但是张炜小说中的一个创造，而且也是其作品的诗意的主要源泉，它在《九月寓言》之后的衰退，不但表明了张炜小说中诗意的衰减，而同时也反照出当代中国社会城市化和世俗化进程的不可违拗；二是精神意义上的"写作主体投影"的变化，其特征主要表现为作为作家思想代言者的"正面的知识者"形象的弱化，代表其另一面的"积极反抗的多欲者"的凸显，这也显示了当代知识分子价值的困境与调整；三是在"文体上的多变与另类化"，由《古船》的"史诗体"，到《九月寓言》的"神话体"，再到《柏慧》、《家族》的"倾诉体"，《外省书》的"纪传体"，《能不忆蜀葵》的"诳语体"，其文体不断求变，也逐渐走入了异书模式和另类叙述。

Finally, the run-length of data points are extracted by horizontal projection, and the modules corresponding to the run-length are taken to decode.

着重阐述了空间直角坐标系之间的转换关系，并为实现这一转换进行了实践操作，在转换过程中运用了高斯投影的反变换、大地坐标系与空间直角坐标系之间的转换等诸多理论。

The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

设计了四片非球面组成的离轴式反射系统，然而，仅采用非球面设计系统结构不够精简，性能也有待进一步提高，且非球面面形较大时加工和检测都存在一定的困难；继而提出了用球面Fresnel反射镜代替非球面的设计方法，虽然Fresnel反射镜加工和检测更为简单，且复制成本低，但对波长具有选择性；进而，应用折反系统结合的方式设计了离轴式投影镜头，该方法因兼具折射和反射的优点，在大屏幕超薄背投系统的设计中广为应用，缺点是会产生难以校正的色差，且结构复杂。

推转项的引入破坏了时间反演对称性，单粒子角动量在内禀对称轴上的投影量子数已不再是好量子数。

In order to solve the problems in system of four aspheric mirrors, Fresnel mrirror and the catadioptric projection lens, the method that free form surfaces were used to design ultra-thin imageing system was put forward at last.

为了解决上述四片非球面系统、Fresnel反射镜和折反系统结合投影镜头存在的问题，本文最后提出了采用自由曲面设计超薄成像系统的方法。

We also analyzed the leg bone proportions of 14 species of Mesozoic birds from the Early Cretaceous of China by using ternary diagrams and comparison with 21 specimens of Cenozoic birds, and concluded that the Early Cretaceous enantiornithines are typical arboreal birds, more basal birds from the Mesozoic are mainly arboreal with some adapted for scansorial life, and the ornithurines are characterized by both arboreal and terrestrial adaptations.

在此基础上，对中国中生代14例鸟类的栖息习性进行了分析，利用三元投影的统计方法，并以国内外新生代21例鸟类标本作为对比参考，得出辽西中生代不同类型鸟类的栖息行为特征：基干鸟类以树栖为主要习性，其中个别鸟类还具有攀援的习性，而反鸟类则是典型的树栖鸟类，今鸟类兼有树、地栖的习性。
