介绍了用滤波器组重构多阶采样信号的原理 ,并且利用多阶采样特殊的重构原理以及在降低采样率上的优势 ,介绍了多阶采样在频率选择上的应用。
4) Selection efficiency
选择效率
1.
Satisfactory selection efficiency and background suppression level are achieved.
６蒙特卡罗模拟，作为一种唯象的研究，对于ＬＨＣＰＰ对撞中来自Ｈ→ｒ＋ｒ－，Ｄｒｅｌｌ－Ｙａｎ，以及ｔｔ和Ｗ＋Ｗ－过程的ｅμ事例，用一具有多个输出网点的前馈式神经元网络进行鉴别，对各物理过程均获得了满意的选择效率和本底压低水平。
2.
To study the selection efficiency for 5 traits selected in the swine breeding plan by LE,LD and DR marker in MAS and GAS in 5 discrete generations,respectively,3 closed nucleus base populations were designed: 100,200,300 sows,and 10 boars each population,where the pigs were unrelated.
结果表明,利用DR标记在各种情况下都比利用LD和LE标记获得的选择效率高;5个性状中,MAS对低遗传力、限性性状NBA的选择效率最高;当性状的QTL方差占遗传方差基本相同时,中等遗传力性状FCR的选择效率比高遗传力性状BF的更高;当性状的遗传力差异不大时,QTL方差占遗传方差比例大的性状FCR的选择效率比QTL方差占遗传方差比例小的性状ADG的更高。
5) choice efficiency
选择效率
1.
Internal production efficiency in firm is determined by external consumers′ choice efficiency.
有效率的生产效率,是由厂商外部消费者的选择效率的高低来决定的。
2.
It proves that the brand declines choice cost and improves choice efficiency that decides production efficiency of the enterprise.
本文通过对选择爆炸式增长的描述,抽象出一般选择过程模型,并深入分析这一过程中所发生的成本及构成,证明品牌正是通过降低消费者的选择成本提高了选择效率,而企业外部顾客的选择效率决定了处于过剩阶段企业的内部价值的实现和内部效率的高低。
