The above method can be used as a general method of determining molecular weight distribution of polymers.4.Solid-state ~1H wide-line NMR and ~(31)p magic angle spinningNMR were applied to a series of PEI/DNA complex samples with different PEI molecular weights and nitrogen/phosphatemolar ratios,in order to disclose the influence of various structural factors on the interactions and morphology.The results of ~1H NMR spectra showed that the linewidth of the PEI signal was greatly broadened with increasing the N/P ratio.Meanwhile,in the ~(31)p M_AS experiment,the signal was found to shift upfield with the increase of the N/P ratio.Both ~1H and ~(31)P NMR experiments demonstrated that the interaction between two constituents and subsequently the morphology of the complexes vary with the N/P ratio.

1St, Luo grain was truly the worker has made the mistake, we will correct 2 in the following sample, because in the order form, has not mentioned this model of scarf's conclusion way, therefore the factory was before pulled the way did, was sorry, we will press your request and the reference diagram manufacture pre-natal type 3, because scarf's span was 64 ", gibbed long 4 ", and in the design drawing, requested scarf's two homochromies, this was unable to achieve, therefore the factory in the permission error range, has adjusted the altitude which gibbed, guaranteed the total lengthWith matches colors correctly, please give your opinion,(the note: This section does not use translator, is only facilitates everybody understanding, the scarf is the black salt bi-color strip, also requests two is the gray, gives the size according to the order form, can only make 16 strips, therefore is impossible to achieve two homochromies, can only make 15 statures, or 17 statures only then the line) dyes the big goods gauze approximately to need for 5-7 days, afterward can prepare the pre-natal type, waited for that your reply opinion, thanks

外贸新手，第一个自己的订单，比较紧张，怕语气拿捏不好，请教各位啊：关于您的意见： 1，罗纹确实是工人做错了，我们会在后面的样品中更正 2，由于订单上，并没有提到这款围巾的收尾方式，所以工厂是按照之前打样的方式做的，抱歉，我们会重新按您的要求和参考图制作产前样 3，因为围巾的全长是64&，夹条长4&，并且设计图上，要求围巾的两头同色，这是无法做到的，所以工厂在允许的误差范围里，调整了夹条的高度，以保证总长和配色正确，请给出您的意见，(注：这段不用翻译，只是方便大家理解，围巾是黑灰双色条子，又要求两头是灰色，按照订单给出的尺寸，只能做16个条子，所以是不可能做到两头同色，只能做15个条，或17个条才行)染大货纱约需要5-7天，之后才能准备产前样，等待您的回复意见，谢谢问题补充：别整翻译工具。。悠关前途''谢谢

Its rule of change was obtained.On the basis of other studies,the flocculation kinetics and floes structure was studied. By making some assumptions, collision frequency were presented.Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict floes number and size during flocculation of Yellow River's loess particles without using empirical parameters.The TEM and SEM were used to obsever floes in the study of floe structure.The flocculation was divided as flocculi,floc and floe aggregate.The floes structure model was established by assumption that particles position in floe accords with tetrahedron.The fractal dimension of model and experimental floes was found to be coincidentSo the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent

最后，本文还对絮凝动力学和絮体结构进行了研究，在前人研究的基础上，针对高分子絮凝黄河泥沙，对絮凝过程作了一些符合试验条件的假设，建立了颗粒碰撞频率表达式，应用了颗粒数量平衡方程，从而建立了絮凝过程的动力学生长模型，模型计算结果与试验数据对比表明，二者趋势一致，在没有使用经验参数的情况下基本上能够描述黄河泥沙絮凝过程中絮体数量和尺寸分布的变化过程；对絮体结构的研究中，应用扫描电子显微镜和透射电子显微镜对絮体进行了观察，将絮体分为絮粒、絮团和絮网三个不同的生长阶段，通过假设颗粒结合位置符西安建筑科技大学博士学位论文合正四面体，建立了絮体结构模型，计算得到的模型絮体分形维数基本与试验中的实际絮体相符，在一定程度上能够反映高分子絮凝黄河泥沙生成的絮体结构。

If as a result of body shell keycap stuck with the key causes of the "key card" failure, may be key in the cap and put a gasket between the pads can be used稍硬some plastic (such as floppy disk jacket abandoned) made, its size is equal to or slightly larger than the key body size, and location by the rod through the ammonium can open a free passage under the square hole, in accordance with its set of poles, the plug cap; use this pad chip cap with the key body to prevent stuck, you can repair button; If as a result of spring fatigue, shrapnel resistance causes large card key failure, then the Special button to open the body, a little stretching to restore flexibility to reset the spring; Remove the key precursor to the resumption of shrapnel.

若是由于键帽与键体外壳卡住的原因造成&卡键&故障，则可在键帽与键体之间放一个垫片，该垫片可用稍硬一些的塑料做成，其大小等于或略大于键体尺寸，并且在按杆通过的位置开一个可使铵杆自由通过的方孔，将其套在按杆上后，插上键帽；用此垫片阻止键帽与键体卡住，即可修复故障按键；若是由于弹簧疲劳，弹片阻力变大的原因造成卡键故障，这时可特键体打开，稍微拉伸复位弹簧使其恢复弹性；取下弹片将键体恢复。
