扩展的

3According to the contradistinguish of all kinds of FFT processing architecture, the design thoughts, rule, method, the characteristics of radix mixed FFT algorithm meets the requirements of scalable FFT architecture. The other FFT algorithms have their own limitations.

3通过分析和比较各种FFT算法的特性和规律后得出，基于FPGA设计傅立叶变换点数可灵活扩展的高速FFT处理器，高组合数FFT算法是最优选择，基一X这种任何基FFT都有扩展的局限性，因为后者是前者的特例，对前者的研究可以得出一般规律的总结，使得高速FFT处理器的结构扩展更为方便和灵活。

In this paper we introduce the FITS basic format, the random-groups extension and the ASCII table extension for the images and catalogs of astronomical data, and the FITS blocking and the rules of the generalized extension of FITS format.

本文介绍了 FITS 的基本格式及其对随机组矩阵的一般扩展，和用于天文星表的表扩展格式，最后对FITS 格式的块结构与其扩展的一般规则也作了详细的介绍。主题词： FITS 数据格式数据结构。

The extended order is human spontaneity cooperation. All actions of the enterprise are around the extended order. The inner institution of enterprise is the microcosmic embodiment of the extended order.The enterprise institution that depends on the exterior compulsory power has no long-last vitality.

扩展秩序是人类自发的不断扩展的合作秩序，企业所有的活动都是围绕着扩展秩序展开的，企业内部的制度也是扩展秩序在微观上的体现，靠外部强制力催生的企业制度没有长久的生命力。

In order to interpret the impact from different intensity of friction factors on urban development, a new model is developed by adding incidental cost and friction factors to the traditional Thunen Model.

为此，传统的杜能模型需要进行扩展，在原始模型的基础上加入偶然成本以及影响城市扩展的摩擦因子以对其进行完善，以便解释摩擦因子的不同强度对城市扩展的不同影响。

When NASM is generating a listing file from your program, it will generally expand multi-line macros by means of writing the macro call and then listing each line of the expansion.

当NASM从程序生成列表文件时，它一般这样扩展多行宏：写出宏调用然后列出扩展的每一行代码。

On the research of the propagation of the fatigue crack in the past 10 years, Paris and Zheng-hart have developed good formulas of the propagation of the fatigue crack of metal , but of which only describe the process of the propagation of the fatigue crack.

在近几十年对疲劳裂纹的扩展的研究中，Paris和Zheng-hirt对金属材料疲劳裂纹扩展的研究给出了很好的扩展表达式，但都是对疲劳裂纹扩展部分过程的描述。

At pentad 31 or 32 and after monsoon onsets, precipitation, convection, low-level west wind and SST extend northeastward, and at nearly pentad 41 they arrive at the most northeast zone quickly, and then their intensities decrease, but they still have a trend of extending eastward.

在31或32候(6月初)季风爆发后降水、对流、西风和海温开始向东向北扩展，在41候(7月下旬)左右时都迅速达到最北地区，之后强度减弱，但仍有向东扩展的趋势。

The result shows that urban landuse growth in Wuxi City has distinct phase character since 1978, which reflects the course of urban development and maturily. Owing to the diversity of local nature, traffic, society and economy condition and the leading of policy, spatial distribution of urban construction landuse growth in Wuxi City has distinct diversity and strong centripetalism. The central city landuse growth has distinct leading direction at different period of time. And the central city has so strong attraction and radiation force to the market towns that dominate the direction of landuse growth of the market towns scattered around a certain distance.

研究表明：改革开放以来，无锡市城镇建设用地扩展具有显著的阶段性，用地扩展模式反映了城市发育、成长乃至成熟的历程；自然交通、社会经济条件的差异以及政策的引导，无锡市城镇建设用地扩展的空间方位差异显著，具有较强的向心性，主城区不同时段扩展的主导方向明显，对其周围集镇具有强大的吸引力和辐射力，它主宰着周围一定范围内集镇用地发展方向。

Even though at a very low temperature (-196℃), the cleavage cracking dominates the fracture process, it can not propagate straight forward through entire ligament and shows the pop-in extension in macroscopic tests and the quasi-cleavage mode in microscopic feature. It is found that the strong resistance which hinders the crack propagation is provided by three barriers: original austenite grain boundaries, bainite colony boundaries and inter-layers between bainite laths.

在－196℃的极限温度下，准解理开裂控制了整个断裂过程，但它仍然不能扩展通过整个韧带，在宏观曲线上出现POP-IN的扩展特征，微观上表现为准解理特征和韧性撕裂特征断口交替出现；同时发现阻止裂纹扩展的阻力来源于三个方面：原奥氏体晶粒边界，贝氏体团边界以及贝氏体片。

It is clarified for the first time that the thermal fatigue failure of solder joint is actually a creep strain low cycle fatigue failure, and a physical model for creep fatigue crack propagation has been proposed. It was pointed out that creep strain increases in the high stress area ahead of the tip of thermal fatigue crack, results on one hand that the slide of crack tip increase, inactivation more serious and crack close length increases, the other hand, that intergranular crack exists, whose direction will affect the fatigue crack propagating.

本文首次阐明了焊点的热循环失效本质上是以焊点内循环蠕变为主要应变的低周疲劳失效，并在此基础上提出了蠕变疲劳裂纹扩展的物理模型，指出热循环裂纹前端的高应力区内，蠕变加剧，使裂纹前端滑移增加，裂纹钝化加剧，导致随后的裂纹闭合扩展长度增加；同时蠕变也使裂纹前端的高应力区出现晶间裂纹，蠕变沿晶裂纹对主裂纹扩展的影响取决于沿晶裂纹的连接方向。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
