And the only allowed Raman band in the first-order diamond spectrum near 1332 cm^(-1) decreases and can't be observed in the micro-Raman spectrum of the film. Three Raman band near 1147 cm^(-1), 1364 cm^(-1) and 1538 cm^(-1) lie in the spectrum which are similar to the reported nano-diamond films.

在该薄膜一阶微显微拉曼光谱中，1332 cm^(-1)附近微晶金刚石的一阶特征拉曼峰减弱消失，可明显观测到的三个拉曼散射峰分别位于1147 cm^(-1)、1364 cm^(-1)和1538 cm^(-1)，与己报导的纳米金刚石拉曼光谱类似。

Another part of our work begins with definition of multioutput generalized bent functions. We show their spectral characteristics and give equivalence definition using generalized first order Chrestenson cyclic spectrum. Also we calculate rate of accordance between multioutput generalized bent functions and multioutput m-valued affine functions. Then we define multioutput m-valued perfect nonlinear functions and show relationship between them and multioutput generalized bent functions. Finally we give two ways of constructions of multioutput generalized bent functions.

研究表明，在波长400~679 nm的范围上，可以根据其反射值的高低，将蔬菜分为两组，一组为大白菜、豌豆、牛皮菜和青菜，另一组为葱、大蒜和香菜。

This paper points out that as the peak of the first order wind spectrum situated at a region of very low frequency, the contribution of the sum_frequency part to the second order wind spectrum is no longer negligible.

本文指出，由于风速谱与波浪谱不同，它的能量峰值位于极低频率处，因此二阶风速谱中和频项的贡献不能忽略，为此本文首先导出了保留和频项情况下的二阶风速谱表达式，并将和频项与差频项在数值上作了比较。

The databases of NIRDRS for Hypericum、 Eucalyptus globules and broussonetia papyrifera were established within suitable spectral ranges with three kinds of data block(original spectrum, first-order derivative spectrum and second-order derivative spectrum) to discriminate unknown samples.

分别用三种数据块(原谱、一阶导数光谱、二阶导数光谱)在不同的谱区范围建立了金丝桃、蓝桉、楮实子3种中药材的NIRDRS指纹图谱库，对未知样品进行鉴别。

It is found that,in a first-order differential Raman spectrum,almost all noise peaks are confined within a narrow horizontal band-like region with the base line going through its middle,whereas thesignal peaks shoot up and down much far beyond the region.Based onthis property,a new peak searching method with the aid of first-order differentiation is suggested.In this paper,a R_spectrumpeak labelling program for SPEX 1403 laser spectrometer with DMIBcomputer is reported.The result of peak labelling sho...

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
