In the case of a " gold standard " two identical cells domains , a highly available database can pretty much assure session failover between domains , while with memory to memory , there can only be a single replicator common to the two cells ; hence , it becomes a single point of failure spof 对于“黄金标准” （两个相同的单元/域） ，高可用性的数据库完全可以确保两个域之间的会话故障转移，而对于内存到内存复制，两个单元只能有一个通用复制器；因此，它就变为单点故障( spof ) 。
The process of initial culture showed quite difference in various hostas . h . ventricosa and h . " so sweet " were easier , while h . " frances williams " and h . " gold standard " were difficult . using shoot tip ( peak bud ) as explant was proved the effective method for improving survival ratio when hostas would defoliate or have defoliated in autumn or winter rather than in summer 玉簪属不同种类的组培初代建立存在着一定的差异，如h . ventricosa和h . ‘ sosweet ’较容易建立，而h . ‘ franceswilliams ’和h . ‘ goldstandard ’比较困难；应在冬季玉簪属植物将要落叶或已落叶后取茎尖(顶芽)进行初代建立，最好避开夏季，来提高初代建立的成活率。
