Channel response in OFDM systems varies with time as to corrupt the orthogonality between subcarriers. This gives rise to intercarrier interference and degrades the performance of signal detection.

由于实际信道的时变性，OFDM系统中每一子载波上的接收信号受到其它子载波上所传输信号的影响，形成载波间干扰并造成误码性能降低。

For example, IEEE 802.16e supports vehicle speed up to 120 km/hour, and IEEE 802.20 supports vehicle speed up to 250 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。

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.

By the quantitative analysis of flavonoids from the extract under acid hydrolysis condition, it is demonstrated that the level of isoquercitrin degrades along with the content of hydrochloric acid elevating and the level of kaempferol is reverse. Those reveal that there exist flavonoid conjugates whose aglycone is kaempferol in the leaves.

对青钱柳酸水解液中成分的测定表明，随着酸浓度的提高，异槲皮苷的含量下降，槲皮素的含量上升，山奈酚的含量也随酸浓度上升而增高，表明青钱柳中尚有以山奈酚为苷元的黄酮苷存在。

Constant value of vena contracta coefficient has been employed in the well-used quasi-steady models for computing the nonlinear acoustic impedance of the orifice. However, this nonrealistic assumption degrades the accuracy of the theoretical models.

常用的小孔声学非线性效应的准定常模型采用不随声强变化的vena收缩系数，这种不合实际的假设影响了非线性声阻的计算精度。

The branched nature of glycogen makes it more accessible to glycogen phosphorylase during degradation, since this enzyme degrades the molecule by sequential removal of glucose residues from the nonreducing ends.

糖原的支链性质使它在降解时更易接近到糖原磷酸化酶，因为这种酶降解分子是从非还原端依次去除葡萄糖残基。
