What happens to the unbranched glucose residues in amylopectin during the methylation and hydrolysis procedure?

在甲基化和水解过程中不分支的葡萄糖残基会发生什么变化？

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。

All this can be managed within the digital simulation paradigm and no analogue simulation is required.

而上述的这些变化都可以在纯数字仿真的乐园中进行不需要任何的模拟仿真。

The 1.5x zoom lens has enough range to move back and forth from 2.35 to 16:9 if the user wishes to set up a 2.35 CIH system with zoom changes rather than the anamorphic lens.

的1.5倍变焦镜头，有足够的范围，摆脱2.35来回16时09分，如果用户希望建立一个2.35 CIH病毒系统变焦的变化，而不是变形镜头。

Therefore, based on documents reports, through contrastive observation of 20-month-old natural senile mice, this study has confirmed that the anaplasia of subacute senile model mice was obviously similar to the features of 20-month-old naturally physiological senile mice. Mice in both two groups displayed dull color patterns, slow movements, insensitive responses and decrease of growth rates of body weight; hepatic and brain tissues in the mice presented senile features of sero-enzyme such as decrease in SOD activity, increase in content of lipid perhydrides and so on.

为此，本研究在文献报道基础上，通过与20月龄自然老化鼠的对比观察，证实：亚急性衰老模型鼠的退行性变化与20月龄自然生理性老化鼠特征的相近之处鲜明可见。2组均出现毛色暗淡，少有光泽，动作迟缓，反应不灵敏，体重增长率下降；肝、脑组织出现SOD活力下降，脂质过氧化物含量增高等血清酶学的老化特征。

The results show the low-pressure andalusite sequence metamorphic belt is not a normal metamorphic sequence.

这些表明阿尔泰低压型变质序列不是一个正常的变质演化系列，显示了变化的野外梯度。

During the testing phase I have been having more fun playing in the Faroes, Andorran and San Marino Leagues than I got from the English League as it is a whole new world for me to explore.

对我来说最大的变化是fm2010为所有的玩家打开了一个完整的足球世界，测试期间我玩了法罗群岛、安道尔、圣马力诺的联赛，而不是英格兰联赛，因为那是我可以探索的新世界。

Leave structure of gymnosperm is less changable than that of angiosperm, and thus it is valuable in classification.

裸子植物的叶在结构上比被子植物的叶变化较少，而且不受环境的影响，具有一定的分类学价值。

Under the vertical load, the strength of rock mass is higher when there is only one group of joint and the dip angle is less than 20 or higher than 80; When dip angle is between 20 to 80, the strength of rock mass is much lower, it is smallest when dip angle is about 50, and it is lower when this kind of dip angle is in combination with other angle.

7在铅直向荷载作用下，岩体中只存在一组倾角小于20°或者大于80°时，岩体的强度相对较高；当岩体中存在一组节理的倾角在20°～80°间时，岩体的强度值很小，而且在与其他倾角的节理组合时，岩体的的强度值变化不太大，特别是当节理倾角为50°左右的时候，岩体的强度相对最低。

This results show that the variation of projection angle across the field of view will not introduce significant errors.

因此，投影角跨视场的变化在采用本装置进行高度测量时不是关键的。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
