1) Water swivel
旋环
2) bHLH
螺旋-环-螺旋
1.
Most silk gene transcription factors belong to HOX and FOX family,the bHLH transcription factors are uncommon.
通过基因芯片数据的检索,我们发现了在家蚕丝腺特异表达的并且含有bHLH结构域的转录因子——Bmdimm和Bmsage,bHLH(螺旋-环-螺旋)结构域能与DNA特异结合从而调控基因的表达,其中Bmdimm在后部丝腺特异表达,Bmsage在中部和后部丝腺特异表达。
3) Cavity rotating
型环旋转
4) spiral ring
螺旋环
1.
After the spiral rings are set up,the original tube boundary layer is destroyed.
研究结果表明:分叉管路分叉点为一扰动源,会诱导附加湍流;管内设置螺旋环后,原管壁边界层遭到破坏,管壁邻近的气流经过螺旋环时,发生边界层的分离,在分离区形成涡流,使气流湍流度增加;火焰阵面进入螺旋环扰动区后,发生扭曲并产生褶皱,火焰表面积显著增加,燃烧速率增大,并相应增加了释热速率,诱导激波的产生。

5) helical cyclophane
螺旋环芳
1.
In this paper, (R)- and (S)-2,2'-diethynyl-1,1'-binaphthyl with highly stable chiral configurations were em- ployed as structural templates, and a new type of helical cyclophane compounds (R,P)-3 and (S,M)-3 were synthesized in enantiopure form by the introduction of benzyl sulfone through Sonogashira coupling reac- tion, followed by the treatment of disulfone with lithium diisopropylamide (LDA).
基于2,2'-二取代的联萘衍生物在手性构型上高度稳定的特点,分别从光学活性的(R)-和(S)-2,2'-二乙炔基-1,1'-联萘结构模板出发,通过Sonogashira偶连反应导入苄基砜,然后用二异丙基氨基锂(LDA)处理制得的联萘二砜成功地合成了一种新的螺旋环芳分子——对映异构体(R,P)-3和(S,M)-3。
