Meanwhile,a typical cylindrical box type window is calculated and used as an example to discuss the power capacity, the special harmfulness and elimination of ghost mode resonance when the window is used to transmit high power Continuous Wave(CW).展开更多

The phase-inversion technique was employed to form macropor-ous chitosan beads, which were then simultaneously acti-vated, cross-linked and connected with a long spacer arm via the reaction with ethyleneglycol diglycidylether (EGDE). Tryptophan (Trp) was subsequently coupled to the ep-oxy-activated beads. This adsorbent demonstrated satisfac-tory adsorption capacity and selectivity for LDL, and it also exhibited excellent blood compatibility. The effect of spacer arms with different length on the adsorption selectivity was investigated experimentally, and the mechanism was ana-lyzed.展开更多
