线性压缩的主给特征是不对各阶调段等比例的调零，线性压缩并不代表假冒的触觉上的等比例压缩，因为D－Y弧线也是否线性的，经功这种压缩后，平调停人眼不便当鉴别，爆不收&灰陡&本体。

Considering there are four output channels in the CCD, the diamond linear array model is replaced with a new two-angle tree linear array in order to improve the performance of the wave-front processor. This change was successfully proved in the 127-element Adaptive optical system and a speed up near the theory limitation is achieved also.

本文第六章利用菱形线性阵列结构设计了波前处理机的硬件平台，并针对光电探测器多通道输出的特点，将菱形线性阵列改进成二叉树线性阵列并成功运用在127单元自适应光学系统中，取得了接近理论极限的加速比。

As applications of the method, the linear wave making problems of Wigley hull and Series 60 hull are solved, with less collocation-points than that in traditional panel method, and the Kelvin wave-patterns calculated are in accord with the test data. Reasonable Kelvin wave-pattern and wave resistance of a high-speed round-bulge ship with transom stern are obtained by enforcing a condition, resembling Kutta-type condition, of smooth flow detachment at the transom stern. In addition to that, the linear solution of a catamaran is also presented.

本文运用该方法求解了Wigley船型与系列60船型的线性兴波问题，以较少的配置点计算出了与实验结果相近的Kelvin波系及合理的波形阻力；以在方尾部强加类似于库塔条件的光滑分离边界条件求解了高速圆舭型方尾船的线性兴波问题，得到了合理的三维波型及波形阻力；另外还求解了双体船的线性兴波问题。

This method applies the extended strip theory to establish the nonlinear ship motion equations in regular head seas, obtains stable time course by resolving in time domain, and then pressure vectors will be available.

关于线性切片理论：线性切片理论本身已经发展成熟，但已有的基于线性切片理论的船舶运动与波浪载荷预报软件系统存在着某些不足之处，在短波长情况下，往往不能给出合理的结果。

Also, the establishment of logistic regression model proves that the choice of stock delivery valuation methods doesn't vary greatly by political affairs and cost of contract, while the establishment of multiple linear regression model bears out that there is a statistics significan ce between accounting evaluation, accounting profession judgment from listed companies' non-circulating assets value depreciation and reflux and the scale of major business income and the relation of high and low ratio of debt to equity. Yet, there is no statistic significance between the relationship of the publication of interest encouraging plan and company establishment date.

在此基础上，本文抽取了实施新会计准则体系之前2005年我国上市公司样本，通过建立有序分组的线性趋势检验模型研究证实，以0.05为显著水平，我国上市公司存货收发频繁程度与发出存货计价方法简化程度之间，并不显著存在一般认为应有的线性关系，排除了发出存货计价方法选择这一混杂因素的影响；进而，通过建立logistic回归模型证实，发出存货计价方法的选择也并不显著受政治和契约成本的影响；通过建立多元线性回归模型证实，上市公司对非流动资产减值的会计职业判断，与其主营业务收入的规模和负债权益比率的高低之间的关系有统计学意义，与是否公布股权激励计划和公司成立时间之间的关系没有统计学意义。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
