色度

Objective To investigate whether the chroma of natural teeth in cervical, middle and incisal position are consistent with Vita Classical shade guides in the same position.

目的：探讨分析天然牙与同名色系的Vita Classical比色片颈部、中部、切部的色度值是否一致，是否具有可比性。

Objective: the purpose of this study is to explore the processing inde pendence between color and luminance in the visual receptor level.

目的 ：在视觉系统感受器水平上研究色度和亮度加工的独立性。

The main purpose of this paper is to identify and diagnose the cucumber's downy mildew intellectively by computer image process technology.

本论文以计算机图像处理技术为重要技术手段，综合运用图像处理、植物生理学、色度学、模式识别等方面的知识，研究利用计算机图像处理技术进行黄瓜霜霉病的病害识别与诊断。

Compared with determination of the chroma and melanoidin, the influences of drying temperature on two indexes were attained.

在凋萎温度48~52℃和焙焦温度78~82℃条件下麦芽色度与类黑精含量的回归方程为：y=1.7048χ+0.0554，r为0.995，呈良好的线性相关。

The application of low pressure boiling technique could increase wort boiling temperature to 100.5 ℃ and advance protein agglomeration and reduce solidifiable nitrogen content to 0.5 mg/100 mL. Maillard reaction and Brown reaction were strengthened in the boiling, melanoidin and melanoid compound contents increased, wort chromaticity improved, and the oxidation resistance of wort strengthened. Besides, the boiling intensity dropped from 9 %～12 % to 7 %～8 % and boiling time shortened to 10～20 min, which improved production efficiency and saved 20 % energy and improved beer non-biological stability.

采用低压煮沸工艺，可提高煮沸麦汁温度至100.5 ℃，加强蛋白质凝聚，麦汁可凝固氮下降0.5 mg/100 mL；煮沸过程加强了美拉德反应、&棕色反应&，类黑精、类黑素化合物增加，麦汁色度增加，麦汁的抗氧化能力增强；煮沸强度从9 %～12 %降至7 %～8 %，煮沸时间缩短10～20 min，提高生产效率，节约能源20 %；改善啤酒非生物稳定性。

Use the method that the article determines to authority is worth, methylic to synthesis acrylic acid the course of two kinds of chemical industry of armour ester, namely different butene law (I-C4) and propylene law (C3) undertook green spends evaluation and analysis, make clear I-C4 law course more green.

采用本文确定权值的方法，对合成甲基丙烯酸甲酯的两种化工路线，即异丁烯法(i-C4)和丙烯法(C3)进行了绿色度评价和分析，表明i-C4法路线更为绿色。

This paper do research on the effect of pH value,concentration of wastewater and retention time on the removal rate of dyeing by iron-carbon microelectrolysis method(including static experiment and dynamic experiment).

采用铁炭微电解法，以自配的染料废水和实际染料废水为研究对象，通过静态和动态实验分别研究了pH、原水质量浓度、停留时间等因素对废水色度、COD去除效果的影响。

Color management can be done through two channels: colourity and microspectroscopic.

色彩处置可以堵住两个道路来达成：色度和平谱。

Monobloc construction (i.e., two separate power amplifier boxes) is always audibly superior, due to the reduction in crosstalk.

广播单声道建设（比如，两个分立式放大器机箱）总是以听得见为优先，这是由于在色度亮度干扰中的减少。

It has been a difficult problem to figure out efficient methods in treating coking plant wastewater because the degradation is difficult. Homogeneous Fenton reagent is one of oxidation methods which applies H_2O_2 as oxidation and Fe~(2+) as catalyst. In reaction,·OH is one of free radicals with excellent oxidizability.

Fenton试剂法是一种采用过氧化氢为氧化剂、以亚铁盐为催化剂的均相催化氧化法，反应中产生的·OH是一种氧化能力很强的自由基，能氧化废水中有机物，从而降低废水的色度和COD值。
