Standard test method for measuring intrinsic elastic recoil of balloon - expandable stents 測(cè)量氣球反沖力的標(biāo)準(zhǔn)試驗(yàn)方法.可膨脹幅度
C - elastic recoil detection analysis ( c - erda ) spectrum shows that the concentration of helium atoms in he - charged al films is about 7 % 經(jīng)碳原子彈性前沖散射分析( c - erda ) ,薄膜中氦原子濃度可達(dá)約7 % ,且分布均勻。
Pathological studies have suggested that restenosis is mainly correlated to the vessel chronic elastic recoil , the thrombus formation in sites , the migration and proliferation of vascular smooth muscle cells ( vsmcs ) , and the excessive synthesis of extracellular matrix 研究認(rèn)為,冠狀動(dòng)脈成形術(shù)后再狹窄的發(fā)生,主要與血管彈性回縮、損傷部位血栓形成、平滑肌細(xì)胞遷移和增生以及過量細(xì)胞外基質(zhì)合成的關(guān)系最為密切。
Elastic recoil detection technique with high depth resolution has been developed at the hi - 13 tandem accelerator of ciae . with high quality beam which was used for bombarding target , the recoils were detected with q3d magnetic spectrometer following a focal plane detector and a ae - e telescope detector with longitudinal double - room ionization chamber 該系統(tǒng)用高質(zhì)量的重離子束轟擊薄膜或塊材靶樣品,利用q3d磁譜儀及其焦面探測(cè)器和縱向型雙電離室e ? e望遠(yuǎn)鏡探測(cè)器兩套探測(cè)系統(tǒng),在前角區(qū)測(cè)量了靶中各種元素的反沖能譜。
