In the system , the dipoles " appearance and parallel arrangement lead to occurrence of spontaneous polarization , which is the essence of ferroelectrics phase transition . the interaction between dipoles is long - distance coulomb force 鐵電相變的實質是系統中電偶極矩的平行排列導致自發極化的出現,電偶極矩的相互作用是長程庫侖力。
( 2 ) the images of aam were characterized by scanning electron microscope ( sem ) , transmission electron microscope ( tem ) and atom force microscope ( afm ) . the results indicated that pores in the as - prepared aam templates owned nearly the same diameter , parallel arrangement , huge density and formed nano - pore arrays ( 2 )用sem 、 afm和tem等分析方法對aam的形貌進行了表征,結果表明:制得的aam中含有大小均勻一致、排列規整、密度較大的納米孔陣列,為模板-電沉積法制備cdse納米線陣列奠定了良好的基礎。
Designs especially may fold the spring mattress , softness extremely good , the elastic force is extra - heavy , six links springs , cause the human body vertebra and the spring structure by the horizontal material parallel arrangement , helps the spring to comply with human body each kind of does produces parallel returns to the tension , may maintain in the sleep the human body vertebra level to delay the posture , protects your vertebra , stores up your health 特設計可折疊之彈簧床墊,柔軟度極佳,彈性力特強,六環直列彈簧,使人體脊椎與彈簧結構以水平資料平行排列,幫助彈簧順應人體各種支作產生平行回彈力,可保持睡眠中人體脊椎的水平延展姿勢,保護您的脊椎,儲存您的健康。
