dominant shape 中文意思是什麼
dominant shape
解釋
主形-
Strip - shape underground structures such as the tunnels and tubes for various uses can be treated as a beam on elastic foundation under earthquake condition ， although there exists soil - structure interaction ， the foundation soil vibration is dominant in other words ， analysis of earthquake response of the soil is essential to this end ， simplified models ， ( i. e equivalent mass system models based on some equivalence criteria ) are proposed ， instead of a general 3 - d continuum model in this study ， equivalence criteria are proposed and the simplified models are compared the single - mass - string model is proved to be valid and therefore applied to the analysis of earthquake response of the pearl river immersed tunnel
條裝地下結構如隧道、各種埋設管道等一般可看作彈性地基梁進行靜力及動力分析在地震條件下，結構與土相互作用，但土的振動成為主要因素為分析土的地震響應需把基土這一三維連續體作簡化處理，簡化成為等效多質點模型本文著重探討這種簡化模型的建立方法，推導等效方程，通過幾種簡化體系的分析比較，論證單質點串體系的合理性，並將其應用到廣州黃沙芳村珠江水下隧道工程的地震響應分析，為抗震設計提供依據 -
We propose a low - dimensional region - based shape index to retrieve images. the initial step in our approach is to segment images into regions on dominant colors
首先基於主要顏色把圖象分割成區域，然後把分割后得到的區域用作形狀檢索的輸入。 -
According to this, we present two retrieval methods in which color feature is used, one is based on image ' s dominant color and the other is based on image ' s shape
對于彩色圖像，採用了一種基於量化的主色調檢索方法，而且由於顏色特徵相對形狀特徵比較容易獲得，還進而提出了一種利用顏色特徵進行基於形狀的檢索方法。 -
The annual variation of runoff turned to uniform with the landscape patchiness index and landscape diversity index increased, and it turned to extreme with the landscape contagion index and landscape dominant index increased, and it did not relate to landscape shape index
隨著景觀破碎度和景觀多樣性的增大，流域徑流年內分配趨于均衡；而隨景觀聚集度的增大，流域徑流年內分配則趨向集中，景觀形狀對流域徑流調節作用不明顯。 -
By compounding caco3 with pp, the effect of caco3 content, diameter and shape on the crystallization, dispersion morphology and properties of pp / caco3 composites was investigated. the results showed that addition of caco3 into pp decreased the apparent crystal size in perpendicular direction to the ( 110 ), ( 040 ) and ( 130 ) crystallographic planes of ppa crystal, and with similar uniform dispersion of caco3, the dominant factor influencing toughness is the diameter of caco3 particles, but not the decrease of pp crystal size. the toughening effectiveness of nano caco3 is obviously better than that of micron caco3
將caco _ 3與pp進行填充復合，研究了caco _ 3含量、粒徑及形狀對體系的結晶，分散形態及性能的影響，發現碳酸鈣的加入使聚丙烯晶型垂直於（ 110 ） 、 （ 040 ）和（ 130 ）晶面的表觀晶體尺寸減小，揭示了在分散均勻的情況下，影響材料韌性的主導因素不是晶粒尺寸的減小，而是碳酸鈣的粒徑，納米張玲：彈性體及無機剛性粒子增韌增強聚丙烯復合材料的研究碳酸鈣的增韌效果明顯優于微米碳酸鈣。
