查询词典 shift

H-aggregate structure of MH-PPV conjugated main chains gives rise to the energy splitting of the low exited states, which causes the spectrum of LB films to broaden and blue shift comparison to the UV spectrum of solution, but the bandgap is smaller than that of PPV in casting film.

与MH-PPV溶液的紫外光谱相比，聚合物分子的H-聚集使得LB膜的紫外光谱明显变宽而且最低能量吸收峰发生蓝移，但相对于铸膜其光学能垒有所降低，这是由于共轭主链的有序排列导致最低激发态能级的分裂造成的。

It is found and emphasized in the paper that the complete form of differential and integral characteristic theorem automatically incorporates the shift properties in both the frequency and time domains, as well as other important properties of Fourier transform, and so it plays an important role in Fourier transform.

并强调了完整形式的微积特性定理自动地包括了Fourier变换的"频移特性"、"时延特性"等其它的重要特性，因此它在Fourier变换中具有基本的重要意义。关键词：Fourier变换微积特性，Fourier变换的极限定义式，冲激型广义函数，频移特性等

In the condition of long pseudo code and large carrier Doppler frequency shift, the number of FFT points in the conventional synchronous acquisition algorithm is too large, the complex multiplication is of high computational complexity and large time cost, and the parameter evaluation acquired in a long duration is not applicable for carrier tracking because it is too old.

当伪码较长、载波多普勒频移较大时，传统的同步捕获算法进行的FIT点数较多，复数来加运算量大，耗时长，而在校长的捕获时间内，捕获得到的参数估计过于陈旧，无法应用于载波跟踪，为此，文中提出了一种改进的快速同步方法。

This change in the composition of capital flows has been synchronous with a shift in emphasis among policymakers in developing countries to attract more FDI, especially following the 1980s debt crisis and the recent turmoil in emerging economies.

这一变化构成了资本流动与同步在决策重心转移到发展中国家吸引外国直接投资，特别是在80年代债务危机和最近出现的经济动荡。

There is a growing realization that the only effective way to achieve further reductions in vehicle emissions—short of a massive shift away from the private automobile—is to replace conventional diesel fuel and gasoline with cleaner-burning fuels such as compressed natural gas, liquefied petroleum gas, ethanol, or methanol.

H 人们逐渐认识到，唯一有效的方法来进一步减少车辆尾气的排放量——除了大规模减少私人汽车——替换传统的柴油和汽油，用燃烧得更加清洁的燃料，比如说压缩天然气、液化石油气、乙醇、或者甲醇。
