Compare with the lg string method , encapsulated particles treated by dry impact method were well dispersed , processing time was shorter . the effect of size distribution of core particle was also discussed in dry impact method 對用lg攪拌磨和干式?jīng)_擊法制備的復(fù)合粒子進(jìn)行了比較,結(jié)果表明,用干式?jīng)_擊法制得的復(fù)合粒子,子粒子分散性好,且分布均勻、所需處理時間短、復(fù)合效果較佳。
The research works finished in this paper are listed below : 1 . solving the problem in testing of cylinder vessels that the sensors disposition is very rigorous , carrying out study of freewill triangle network orientation and linear orientation , bringing forward the discriminance which distinguish the validity of orientation array using character string method the first time , at the same time , solving the problems that judgement of orientation array , elimination of camouflage location , avoidance of repeat location , etc . 1 ' . carry ing out the study of the orientation of defects in stand lank floor with the method of freewill planar triangle orientation , advancing bran - new discriminance on the validity of orientation arrays , orientation points , and the disposing means of the acoustic sources near sensors and those near common border 本文進(jìn)行的主要研究工作有: 1解決柱式容器檢測中傳感器排布要求較嚴(yán)格的問題,開展任意三角形網(wǎng)絡(luò)排布檢測技術(shù)與線定位技術(shù)研究,首次提出了利用字符串格式判斷線定位陣列有效性的判別方法,并解決了任意三角形定位中存在的定位陣列判斷,偽定位的剔除,重復(fù)定位的避免等一系列問題; 2利用平面任意三角形定位方法開展常壓立式儲罐罐底缺陷定位技術(shù)研究,提出了全新的定位陣列有效性判斷、定位點的有效性判斷方法;以及頂點聲源和邊界聲源的處理辦法。
