铬

The methods used to determine COD of water sample are "potassium dichromate reflux method" and "open focused microwave digestion".

在COD的分析方面，采用的方法为"含高浓度卤离子水中化学需氧量检测方法─重铬酸钾回流法(NIEA W516.53A)"，简称高卤法，及"开放式聚焦微波消化法"，简称微波法。

The surface film formed at higher potentials consisted of oxides of Ni in predomination with some Fe and little Cr, while that formed at lower potentials was composed of oxides of Cr, Ni and Fe. The latter showed much higher resistance to caustic SCC.

这与较高电位下生成严重贫铬的Ni和Fe的氧化膜，而较低电位下生成由Cr、Fe、Ni的氧化物共同组成的表面膜密切相关。

The development differs from that of tetrapods in that it occurs mainly in the pronephros and only later do chromaffin cells reach the opisthonephric kidney.

开发者不同，它主要是在61%-66%发生及后来做铬到达opisthonephric肾细胞。

In the biochemical analysis aspect, it is first time to use the simple fluorescence spectrophotometer to determine the protein in human serum by red alizarin as the probe of the RLS. The experiment shows that the system HSA-red alizarin has the maximum intensity of the RLS in Britton-Robison buffer of pH4.10 at maximum wavelength of about 360nm. The method has better linear range within 0.040-10.0ug/mL, determination limit is 0.040ug/mL. Moreover, We have selected three other dyes of chromotrope 2R, acid chrome dark blue and pyrocatechin violet as the probes of the RLS in determining protein in human serum and achieving satisfactory results.

在生化分析方面，作者首次使用简易960型荧光分光光度计，利用茜素红作为共振光散射光谱探针对人血清中的蛋白质含量进行了测定，测定结果显示在pH4.10的Britton-Robinson缓冲溶液，波长360nm处出现最大的共振光散射强度，其线性范围为0.040～10.0μg／mL，检出限为0.040μg／mL；另外，作者还筛选了其他三种可用作蛋白质测定的共振光散射光谱探针的有机染料：变色酸2R、酸性铬深蓝、邻苯二酚紫，并深入研究了测定的适宜条件和干扰情况，将这三种有机染料用于人血清中蛋白质含量的测定，均取得了满意结果。

In this paper, we used the ab initio calculation method of quantum chemistry to calculate the molecular structure and nature about the chromium.

本文用量子化学的从头计算方法计算研究了相关铬分子的结构和性质。

Objective: To improve the diagnosis and treatment of recurrent pheochromocytoma.

目的：提高复发性嗜铬细胞瘤的诊治水平。

Chromium was first discovered in the Siberian red lead ore in 1798 by the French chemist Vauquelin.

铬 最早是由法国化学家 Vauquelin 于1798年在西伯利亚赤铅矿石中发现的。

In Luo Zhong-rong"s modern compositions, the pitch organization and the form of it"s structure hold the prominent position and issue significant function in music context, and the researches of these aspects in this dissertation occupied referentially also a more wide space. The first three chapters introduced three kinds of pitch organization used in these compositions: serial set, twelve-tone tonality and pentatonic aggregate.

音高的组织与结构方式在罗忠铬的现代音乐创作中有着十分突出的作用，论文在这方面的研究也相应占据了较大的篇幅，前三章分别介绍了作曲家在这些创作中使用的三种音高组织："序列"、"十二音调式体系"以及"五声性十二音集合"。
