4) scale-up
['skeilʌp]
相似放大
1.
The conditions of the scale-up with the method of thermal transmission,compounding and Maddock to the melted resin in the intermeshing corotating twin-extruder were analyzed with the method of equivalent diameter and three groups of mathematical relationships about the main parameters were obtained.
应用"当量直径"的方法,分析了在啮合同向旋转双螺杆挤出机内高聚物融体热传递相似、混合相似和剪切相似(Maddock)的条件,得到了3组主要性能参数相似放大的关联式。
5) similar shape
相似形状
1.
This paper presents the design and implementation of a content-based image retrieval system which acquires effective and efficient similar shape retrieval using a modified geometric hashing technique.
文中介绍了一个基于内容的图像检索系统的设计和实现,它利用改进的几何散列技术能够获得快速而且准确的相似形状检索。
补充资料:相似三角形
所谓的相似三角形,就是它们的形状相同,但大小不一样,然而只要其形状相同,不论大小怎样改变他们都相似,所以就叫做相似三角形
三角对应相等,三边对应成比例的两个三角形叫做相似三角形
相似三角形的判定方法有
aaa 三个角分别相等,其实只要两角相等就可以了。
sas 两个三角形的两边对应成比例且其两条边的夹角相等。
sss 三边分别对应成比例。
