查询词典 patch plug

In fact, in reallife, the prey species will be usually a?ected by the patchy environment, oncethe food in their patch is exhausted or there are abundant natural enemies intheir patch, they will leave in search for new habitats or refuges, at the sametime, the predator species also will be confined in a isolated patch, when thereis little food to feed on or the last prey is eaten the predators will depart andbecome predator dispersers.

事实上，在现实环境中食饵种群通常会受到斑块环境的影响，一旦在一个斑块上的食物吃完了或者存在太多天敌，它们会离开这个斑块寻找新的栖息地或避难所，同时捕食者种群同样会受到隔离斑块的影响，当在某个斑块上食饵种群稀少或吃完了最后一个猎物，捕食者种群将会离开变成迁徙者到其他栖息斑块上寻找猎物。

To overcome the drawbacks in the weight and cost of the antenna with the corrugated soft surface, a new patch antenna with patch rings is designed. Its weight is about 1/4 less than the antenna with the corrugated soft surface and it is inexpensive. Good experimental results are obtained. The radiation pattern of the antenna is more rotationally symmetric, and a more reduction on the sidelobe levels of the antenna is achieved as compared to the antenna with the corrugated soft surface. In conclusion, in the present thesis both theoretical and experimental research works have been carried out intensively on patch antennas based on photonic-bandgap structures.

为了克服皱褶软表面天线份量重，加工费用贵等缺点，我们对空气介质的皱褶圆环结构软表面天线进行了改进，将周期分布的皱褶圆环平面化，并保持结构的软表面特性，设计出了一种新的平面圆环结构的软表面天线并进行了实验研究，加工的平面圆环结构天线比皱褶圆环结构天线重量减轻了约1/4，加工费用大大降低，所取得的实验结果显示，该平面圆环结构软表面天线的方向图的轴对称性得到了改善，在俯仰角从0°～-90°的范围内天线H面的波束与E面重合，与皱褶圆环结构相比，天线的旁瓣和背瓣受到了更大的抑制，E面方向图上+120°方向的旁瓣被明显削弱。

On the geometric modeling, flat surface and curved surface are used to mesh and describe the model;on the electromagnetic modeling. Different basis functions( flat surface roof-top basis function, flat surface RWG basis function, curved surface roof-top basis function, curved surface RWG basis function) and different test functions (line-matching, Galerkin method) are applied to different cells(plat rectangle facet, triangular patch, Bezier patch, parametric surface, curved triangular patch etc.).

在几何建模方面，分别采用平面元和曲面元对模型进行了剖分和拟合；在电磁建模方面，针对不同的单元(平面元、平面三角元，、Bezier元、参数曲面、曲面三角元等)采用不同的基函数(平面roof-top基，平面RWG基，曲面roof-top基，曲面RWG基)和不同的检验函数进行处理。

The results indicate that, in either single or double blowing, larger erosion rate is mainly found in the slag line and near purging plug area of ladle lining; erosion is accelerated when gas flow rate increases; the erosion rate of ladle lining with double blowing is larger than that of single blowing; erosion rate distribution is obviously different as gas flow rate increases; in heavy blowing, serious erosion centers around slag line area and expands gradually outwards; as purging plug gets close to lining wall, malconformation of erosion rate in ladle lining becomes more prominent and the erosion rate of lining near purging plug increases.

结果表明，无论单吹还是复吹，较大的蚀损速率主要分布在钢包渣线及近透气砖区域，吹气量的增大会加速钢包内衬的蚀损。采用复吹时，钢包内衬的蚀损较单吹时更快。随着吹气参数的改变，钢包内衬蚀损速率的分布状况差异明显。大吹气量下，较大的蚀损集中在渣线区域且呈环向扩展；透气砖安装距包壁越近，钢包内衬蚀损不均衡性也越突出，近透气砖内衬蚀损加重。
