Experimental results showed that both anisaldehyde and anisic acid have an iso-absorptive point in their UV spectra.
结果表明,茴香醛和茴香酸在260 nm有等吸收点,利用紫外等吸收点特性简化混合物各组分质量浓度的计算方程,得出了线性方程:ρ(茴香醛)=(A292-0。
The initial vectors can be construc-ted based on the isoabsorptive points of the different species of the SMZ to ensure that ITTFA can converge to the real solution .
基于各型体等吸收点原理构造初始迭代矢量,确保ITTFA 法能快速收敛于正确的唯一解。
The paper identified strictly the two isoabsorptive points of absorptionspectrum of Fe(ClO_4)_3 solution in ultra-violet range(the wavelengths:271 nm and 222 nm) and then determined successfully the micro-elementFe in tea, licroricl and orange peel by using isoabsorptive point.
本文准确地测定了Fe(ClO_4)_3溶液在紫外区吸收光谱的两个等吸收点(波长为271nm和222nm),并利用等吸收点成功的测定了菜叶、甘草、陈皮等样品中的微量元素铁。
The static correction values are caculated in commonshot, common reciever, and common offset domains respectively, and then the caculated values areadded back to the common-offset first arriva curves.
本文提出一种用大炮初至时间计算静夜正量的新方法，它是在共炮点域、共接收点域、共偏移距域分别计算出静校正量，再把计算出的静校正量回加到共偏移距初至曲线上，若初至时间曲线足够平滑时，我们便认为所求得的静校正量是比较准确的。
In the past, CATV optical cable networks were costliness due to the price of optical equipment, the designer design optical receiver point little.
过去CATV光缆网光设备价格昂贵 ,故设计的光接收点较少。
