The methylated amidogen still held protonation at low pH. Therefore, the adsorption ability of biomass was almost unchangeable through methylation of amidogen in biomass. The acetylated amidogen lost protonation at low pH, and the capacity of dye adsorption of biomass decreased by 51.6% after acetylation of amidogen in biomass.

甲基化氨基在酸性条件下仍然可以质子化，故氨基甲基化修饰后染料吸附性能不变；乙酰化氨基在酸性体系中失去质子化能力，乙酰化修饰菌体染料吸附性能下降51.6%。

To determine the condition of chromogenic reaction between iodine and amylum quantitatively, the author studied the law in the course of chromogenic reaction between iodine and amylum with the aid of spectrophotometer quantitatively, and found that maximum absorption wavelength is 610 nm, and the absorbance in the course of chromogenic reaction between iodine and amylum has not changed within 7 hours.

为了确定碘和淀粉反应的定量关系，本文利用分光光度计定量地研究了碘和淀粉显色反应过程中吸光度的变化规律，发现碘和淀粉显色反应的最大吸收波长为610 nm，碘和淀粉显色反应的吸光度在七小时内基本不变，可以进行比色分析。

When us a domain name is new and analytic go up to new space, all alone Link inputs above engine in search: Www.nongyao168.com inquiry, the retrorse link that can discover this domain name still keeps changeless, these data will be saved all the time update greatly next time till search engine.

当我们把域名重新解析到新的空间上，在搜索引擎上面输入link：www.nongyao168.com查询，会发现该域名的反向链接仍然保持不变，这些数据将一直保存直到搜索引擎下次大更新。

The yolk proteins were collected through the anatomization of the maiden eggs and the eggs in different embryo development stages. The yolk proteins were separated by two-dimensional electrophoresis and followed the image analysis. Over 203 protein spots were found to exist in the yolk protein of silkworm eggs. Some different patterns of yolk protein spots were found in silkworm of various varieties. While, little variation of yolk proteins was detected during different development stages of any silkworm variety.

采用直接解剖蚕卵获取卵黄蛋白，结合蛋白质双向电泳和图像分析，对家蚕处女蛾卵及不同胚胎发育阶段蚕卵的卵黄蛋白质进行了研究，发现家蚕卵黄蛋白有 203 个蛋白质斑点；不同家蚕品种之间卵黄蛋白的组成存在一些差异；同一品种不同发育时期胚胎卵黄蛋白的组成基本保持不变。

The speed also affects combustion noise through variation of advance angle.

推迟供油提前角可以显著降低噪声。2、燃烧系统多参数分析2.1、喷孔数目在喷油压力不变时，减少喷油孔数量，可使促进燃油雾化，使着火延迟期缩短，因而有助于降低压力升高比，汽缸压力频谱线也相应降低，尤其是中、高频成分降的更多些。

Furthermore, finite element program ABAQUS6.5 was also used to simulate experimental course. Results show that the change of ply splice angle will lead to shear stress concentration on 0 ply in splice region. But the average of shear stress along notch root of specimens almost does not change.

采用有限元软件ABAQUS6.5对实验过程进行模拟，得到拼接层角度改变将引起拼接层中0层出现切应力集中，但沿缺口切应力的平均值几乎不变。

For uniform aerosol, the correlation coefficient between remote sensing data and water components'concentrations is constant, whatever the Angstrom coefficient.

对统一气溶胶模型，无论怎样改变气溶胶的Angstrom系数，遥感数据和水体组份数据之间的相关系数不变。

In other words, the magnitude of the angular momentum is increased, its direction remaining the same.

换句话说，即角动量的大小增加了，但其方向不变。

This paper proposes a novel algorithm of Feature Match Based on Corner Affine Invariant. It selects corners as extracting feature of the image matching, and these corners are characterized by their orientation and angular width.

该方法是使用角作为图像匹配选取的特征，通过仿射不变处理来消除图像缩放、扭曲、旋转和平移产生的影响，实验表明，该算法具有良好的匹配性能，可以对差异较大的图像对进行特征匹配

According to the calculated proportion of aniline and dye, if the other reaction condition is maintained, and the proportion in electrolyte is changed, the DS-PAn film with different sensation properties can be obtained, i. e. absorption range and intensity in visible spectrum can be controlled by the proportion of aniline and dye.

实验证实，可以通过预先计算苯胺与染料的比例，在电解液中改变苯胺与染料的比例，保持其他电化学反应条件不变的情况下，在经过一定时间反应后，可在多种衬底上生成不同增感效果的DS-PAn薄膜，同时此薄膜在可见光区的吸收谱带的宽度和强度可由聚苯胺与染料的比例来控制。
