查询词典 unitary invariant

For example, IEEE 802.16-2005 supports vehicle speed up to 120 km/hour. OFDM systems can be used efficiently in time invariant environments with one-tap equalizers. However, subcarriers are no longer orthogonal to each other in time-varying channels, and this causes the intercarrier interference and degrades the system performance.

传统的正交分频多工系统可以有效率地使用在非时变通道中，且仅需简单的等化器，即可修正通道效应，但在移动的环境中，通道随著时间改变，使得接收端的子载波失去正交性，因而导致子载波之间的相互干扰，使得解调变后的效能降低。

TACE and sequential chemotherapy inhibit the development of the cancer synergily and the latter cannot induce the toxic reaction.

化疗药物腹腔给药后门静脉血中，腹腔液中药物浓度显著高于腹主动脉，外周静脉血；腹腔给药后，肝组织中药物浓度高于肾组织；药物在门静脉，组织中存在较高的药物浓度，递减缓慢，浓度恒定，维持时间长；肝动脉化疗栓塞术有效地控制了肿瘤的大小，序贯化疗亦有效地抑制了肿瘤的发展和转移，两者间作用相互协同；序贯化疗不增加肿瘤病人的化疗毒副反应。

However in the study of nucleon spin structure,the gluon spin,quark and gluonangular momenta operators seem to have intuitive physical meaning but are not separatelygauge invariant.

但是在核子自旋结构研究中，胶子自旋，夸克和胶子轨道角动量看上去有直观的物理含意，但却不是分别规范不变的。

The significant advantage of our formulation in that one does not need to carry out the integration over canonical momenta in generating functional and one only requives the andto be invariant under the non-local transformation in non-Abelian Chern-Simons theory.
