住宅区：文华园的3个样地和瑞士花园的2个样地。主要交通干道：大学路的3个样地和民族大道的2个样地。商业区：以人面子为主要街道树的新民路，以红桂木为主要行道树的新竹路，以中国无忧花为主要行道树的圆湖路。调查结果表明：在南宁市四个功能区的24个绿化样地，主要的绿化乔木有 45种，前 10种依次是：人面子、假摈梆、垂叶榕、桂花、扁桃、蒲葵、阴香、马尾松、芒果和中国无忧花，主要的绿化灌木有24种，前8种依次是九里香、尖叶木犀揽、黄叶假连翘、扶桑、花叶朱蕉、紫蒲、短穗鱼尾葵和大花美人蕉，这些植物基本上代表了本市绿化植物的主体。

The mid-temperature vinyl sulphone reactive dyes are the most commonly used in most of domestic dyeing factories at present. Owing to three prime color dyes are the basis of match dyeing ,the stability of the three prime colors property determines the performance of the matched color ,so it is very important to select a team of low cost three prime color dyes with high light-perspiration fastness .

目前国内染厂大多数染色都采用中温型含乙烯砜活性基的染料，由于染料三原色是进行拼色染色的基础，三原色性能的稳定与否决定着拼出的色相的稳定性，选择一组具有较高耐光汗复合色牢度且拼色性能较好的低成本三原色具有重要意义。

Based on the conventional CPB prime, we modified the prime solution using 5% NaHCO3 and 10% MgSO4. At the same time the prime solution were oxygenized through 60% oxygen mixed air.

目的 通过对体外循环预充液的改良调整，观察其对婴幼儿术中内环境及血流动力学的影响。

METHODS 16 congenital heart disease infants weighted below 10kg were studied. Based on the conventional CPB prime, we modified the prime solution using 5% NaHCO3 and 10% MgSO4. At the same time the prime solution were oxygenized through 60% oxygen mixed air. We observed the changes of the blood gas and electrolyte and hemodynamic situation througout the procedure.

16例10kg以下的先天性心脏病患儿在常规预充的基础之上，通过血气结果对预充液进行改良调整并充分氧合，使预充液的内环境更接近机体内环境，记录预充液调整前后及CPB前中后的血气参数和CPB前中后的血流动力学指标。

First,the paper summarized and analyzed the definition of the earth prime meridian in different periods,clarified the ambiguous recognition that the earth prime meridian was the meridian passing Greenwich astronomical observatory and gave the rigorous definition about the Earth prime meridian presently.

首先对地球首子午线在不同时期的定义进行了分析和总结，进一步明确了当前对地球首子午线的严格定义，澄清了地球首子午线即过格林尼治天文台的子午线这一模糊认识。

In the second chapter, elementary theories and ideas of one step forming inverse approach were described and warped modification method, implemented by Cook, was introduced into one step forming simulation and based on idea of surface spreading; new quadrilateral element modification arithmetic was put forward. By spreading warped quadrilateral onto plane in local coordinate system, a plane quadrilateral element whose shape and area were equal to original warped quadrilateral element was gotten and internal force vectors of four nodes and stiffness matrix of elements were improved to increase precision of simulations on this plane element.

第二章从一步成形逆有限元法的基本理论和思想出发，将Cook基于弹性理论的四边形单元的翘曲修正算法引入基于塑性的一步成形，并且基于曲面展开的思想，本文提出一种新的四节点单元翘曲修正方案，通过把翘曲的单元展开的方法在局部参考系中得到一个与实际翘曲单元的形状与面积非常接近的平面单元，在该平面单元中进行单元刚度及内力向量的计算，进一步改善模拟结果的精度。

Firstly it describes the development ,basic principle and application and propagation characteristic of mobile channel , then investigates the system structure of DAB transmitter and receiver separately and the key technology of realization of the digital audio broadcast system.And then discusses the system component of FFT －the demodulation module of OFDM .The 409- points FFT module employs a radix-4 decimation-in-frequency algorithm, includes arithmetic element , read and write address element ,twiddle factor element and control element , is realized by FPGA.
