1.This document identifies the classification level of nonhermetic solid-state surface mount devices (SMDs) that are sensitive to moisture-induced stress.

本标准用于确定非气密封装表面安装件（SMD）湿气敏感度等级。

2.Semiantigen sulfamethoxydiazine (SMD) was coupled with carrier protein bovine serum albumin (BSA) to prepare complete antigen SMD BSA by glutaraldehyde method.

采用戊二醛法,将半抗原磺胺对甲氧嘧啶(SMD)载体牛血清白蛋白(BSA)偶联,制得磺胺对甲氧嘧啶全抗原SMD-BSA。
