查询词典 hemicellulose

Hemicellulose One of a group of substances that make up the amorphous matrix of plant cell walls together with pectic substances (and occasionally, in mature cells, with lignin, gums, and mucilages).

半纤维素：是一类与果胶质共同（有时，在成熟细胞中与木质素、树脂、黏液在一起）构成植物细胞壁的无定形基质。

Fitting curves are in good agreement with the experimental results,the calculated kinetic parameters are in good agreement with those reported in term of modeling of the pyrolysis of the three components assuming hemicellulose,cellulose and lignin pyrolyzing independently and para...

采用非线性最小平方算法，按三组分独立平行一级反应热解动力学模型，模拟计算的曲线与实验结果吻合较好，求解的动力学参数与文献报道值吻合较好，且随着升温速率的加快，纤维素和木质素热解的活化能有增加的趋势，而半纤维素活化能有下降的趋势。

The infra red spectra of specimens show that there are evident changes of waves at the wavelength of 1743, 1660 and 1605cm-1 which are attributed to the change of C=O in wood. So it is clear that at least hemicellulose, even lignin in wood cell chemically changes during heat treatment of compressed wood of China fir.

红外吸收光谱表明，在热处理过程中波数在1743，1660和1605cm-1附近的羰基峰的变化趋势最为明显，说明在热处理固定杉木压缩木材的过程中，至少半纤维素，甚至木素发生了化学变化

The experimental results showed that the optimized parameters for isolation of hemicellulose was: 2% hydrogen peroxide, 2% sodium hydroxide, heating time 4h, reaction temperature 75℃.

结果表明，半纤维素分离提取的优化参数为：2%过氧化氢，2%氢氧化钠，加热时间4h，反应温度75℃。

The corn stalk mainly consisting of cellulose, hemicellulose and lignin is a wealth of renewable resources.

玉米秸秆是一种丰富的再生资源，主要由纤维素、半纤维素、木质素组成。

This study found that there was different digestibility of the cellulose and hemicellulose of roughage between individual sheep mainly because of the difference of digestibility on NEH part by the animal,and therefore it is suggested that the interest in the digestion of fiber material by ruminants should be focused on the digestion of NEH part.

在动物营养研究中，饲料中的纤维素类物质通常被分为纤维素、半纤维素和木质素[1，2]，但实际上这样分类的纤维素、半纤维素自身的营养价值或消化率是有差异的，因为纤维素可以分为结晶型和非结晶型的[3，4]，并且在植物体内纤维素和半纤维素并不是单独存在的，有相当一部分是与木质素

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
