解釋
莖環-
With the generalized algebraic riccati inequality ( gari ) approach, a sufficient and necessary condition for the existence of dynamic output feedback h controllers is presented, such that the resulting closed - loop sy stem is admissible with its transfer function satisfying h norm constraint
利用廣義代數riccati不等式，給出離散廣義系統存在正常動態輸出反饋h控制器，使得閉環系統是容許的且其從外界干擾輸入到受控輸出的傳遞函數矩陣具有h范數約束的充分必要條件。 -
( 8 ) the substitution rate in loop regions is 2. 24 times of that in stem regions. the transition rate is almost same ( 0. 051 and 0. 082 ), compared with the results that the transversion rate of loop regions is the 12. 67 times of that of stem regions
（ 8 ）環區的所有核苷酸堿基代換率為莖區的2 . 24倍，轉換率幾乎相同（ 0 . 051和0 . 082 ） ；而環區的顛換率卻高達莖區的12 . 67倍。 -
Meanwhile, base composition in rrna genes, the secondary structrues of trna and the potential stem - loop structure in the noncoding region were also analysesed in the present study
同時分析了d1na基因的堿基組成、 trna的二級結構、非編碼區潛在的莖環結構。 -
2073 bp fragment of rubisco was cloned, sequenced and analyzed from a. platensis fachb341, including partial sequence of rbcl gene, rbcx gene and rbcs gene. there are two transcription stem - loop termination structures downstream of the 3 " sequence of rbcl gene
分析結果顯示此基因的結構如下： 11230hp為rbcl基因； 1362 1727hp為rbcx基因； 1776 2073hp為rbcs基因： rbcl和rbcx基因之間存在rbcl基因的兩個轉錄莖環結構， 1732上為核糖體結合位點ggag 。
