The first order derivative transfer was carried out in the spectrum data.The first order derivative feature is analyzed.It is shown that:The vegetables can be divided into two groups according to their reflectivity during 400nm to 679nm.

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。

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.

After acquiring the ultraviolet absorption spectrum and its first order derivative spectrum distributions of Avermectin B1 by using UV-2401 PC spectrophotometer and spectrum-measuring system,we found that coordinates of the peak A252.2 and the valley A256.8 are not disturbed by the different forms of preparations.

用UV-2401 PC紫外分光光度计及光谱工作站，以1 nm狭缝宽度，2 nm Δλ间隔，在190～400 nm波长范围内快速扫描采集阿维菌素B1紫外吸收光谱，拟合一阶导数光谱发现峰顶A252.2，和峰谷A256.8在波长坐标上的位置不受不同制剂干扰。
