| 1. | Core area of section 截面核芯面积33 |
| 2. | The tower structure comprises an external steel frame , an elliptical concrete core and steel - framed floors between them 塔体由椭圆型钢结构外筒和混凝土核芯筒以及连接这两者的钢-混凝土组合结构楼面组成。 |
| 3. | By these measures , the problem one can be solved to some extend . in order to solve the problem two , the method of " step by step arranging stirrup " is suggested 主要采取了“分层加箍法”的控制措施,并提出了“ x型核芯箍”的构造措施。 |
| 4. | The 3d parallel super element and the methods of simplifying for calculation of the shear - wall supported by frame and core - tube are presented for practice 结合结构的实际应用,提出了空间并联超单元的简化计算思路,给出了框支剪力墙及核芯筒体的简化处理方法。 |
| 5. | The problem two is the stirrup in the core of beam - column joint was insufficient because of designing or construction . so the shear capacity and ductility of beam - column joint will decrease 框架节点核芯区柱箍漏放或数量不足,引起节点抗剪承载力降低,延性不足。 |
| 6. | The present work provides the first experimental evidence for the theoretical prediction that the second excited state of 6li is a neutron - proton halo state with an a cluster at its center 本论文第一次从实验上证实了~ 6li第二激发态是一个以为核芯的中子-质子晕态的理论预言。 |
| 7. | In particular , different inclined angles and the bind core effect of concealed bracings are considered in the analysis . and the concept of concrete confined is introduced in the concrete of the rims , concealed columns and concealed bracings 分析中考虑了暗支撑的不同倾角及核芯束作用,并在边框、暗柱和暗支撑中的混凝土引入了约束混凝土的概念。 |
| 8. | The investigation on the halo structure of drip - line nuclei is one of the most important subjects and has attracted much attention both experimentally and theoretically . the halo nucleus is a weakly bound system , which has very peculiar properties 晕核是弱束缚系统,具有非常特殊的性质,最外层的价核子具有非常弥散的空间分布,通常采用核芯加晕核子的少体结构近似。 |
| 9. | Recently a few - body glauber theory has been proposed , where the core and halo nucleons are treated separately . we apply the few - body glauber theory to halo nucleus reactions and extend it to the halo nucleus with more than one or two halo nucleons 研究晕核反应时需要考虑晕核各个组成部分之间的空间关联,对此我们应用将晕核核芯和晕核子分开处理的少体近似glauber模型,并且将其推广到了含有多个晕核子的晕核散射。 |
| 10. | Since in the few - body glauber theory the core and valence nucleons of a halo nucleus are treated separately , the obtained expressions of the reaction cross section , the nucleon removal cross section and the momentum distribution are all involved in multidimensional integrations 由于在少体近似glauber模型中晕核被分成核芯和晕核子来处理,所以得到的晕中国原子能科学研究院博士学位论文核散射反应截面、核子逃逸截面以及动量分布的计算公式均包含高重积分。 |
