Methods: Flat-stand method was used to ascertain inhibitory spectrum, Sandwich method, cup-plate method, filter paper method and double deck-stiletto method were used to testing it's antagonistic effect of fermentation liquid. 方法:平板对峙法测定抗菌谱,三明治法、管碟法、滤纸片法和双层打孔法测定发酵液的拮抗能力。
From the polyol system. the polyurethane foams which have density of 30kg/ m3 and good dimension stability and are suitable for continuous sandwich boards can be prepared. By testing, performance of the boards manufactured in a domestic plant has all met demands. 通过选用合适原料、调整配方,研制出泡沫整体密度小于30kg/m3、尺寸稳定性好的用于连续夹芯板生产的组合聚醚,并在国内某夹芯板厂家上机生产,经检测,其所有性能指标均达到要求。
According to the dynamic analysis of the fieldworks that was made of FRP Honeycomb Sandwich, and contracting with testing result and data, the deformation regular and data of fieldworks structure was the same with experiment. 并对浅埋玻璃钢蜂窝夹层工事进行了动力响应计算,计算结果和试验数据分析对比表明,结构受力变形规律与试验基本一致,数据吻合较好。
So in this article the aluminum honeycomb sandwich plates, which have different size artificial defects, were detected by the ultrasonic C-scan nondestructive testing. 本文对含有不同尺寸人工脱粘缺陷的铝蜂窝夹层板试件,利用超声C扫描无损检测技术对其粘接质量进行检测研究。
