Carton: Made of light but strong cardboard, or fiberboard with double lids and bottoms, fixed by glue, adhesive tapes, metal bands or wire staples. 纸箱:一般由坚固轻便的硬纸板做成。上下有盖,用脱水固定,胶带封住,用铁皮或起码钉打包。
Methods 38 patiens were treated with open reduction, and fixed by crossing Kirschner wire and double tensile force bands and early functional exercise. 方法对38例患者行切开复位交叉克氏针加双张力带固定法治疗,并早期功能锻炼。
Troposcatter communication systems based on frequency adaptive technique are able to concentrate total transmitting power on the band around optimal frequency to improve power efficiency contrasting with the traditional ways in which the transmitting signal is on fixed bands. 使用自适应选频通信方式,可以集中所有发射功率在最佳频率上发射信号,避免传统分集技术使用固定频率发射信号衰落时产生的信号功率浪费。
The fractures were reduced and fixed with dual-plates ( DP) in 17 cases, and double tension bands ( DTB) in 13 cases. 双钢板内固定17例,双张力带内固定13例。
However, the frequency resources have different degrees of idleness in time and space dimension because of the fixed spectrum allocation system, even in some more crowded bands, and the actual frequency utilization is not high ever. 但是,另一方面,由于采取固定分配频谱制度,频率资源在时间、空间等方面存在不同程度的闲置,即使在一些比较拥挤的频段,实际的频率利用率也并不高。
