In the Chapter 2 of this dissertation, new pulse sequences were introduced, in which CPMG and bipolar gradient pulses have been implemented into pulsed-filed-gradients spin-echo NMR spectroscopy, and is used to measure the self-diffusion coefficient of metabolites in bio-fluids.

实验结果表明，这种新方法不仅可以在生物体温或更高温度下准确测量分子的自扩散系数，不受对流和背景梯度的干扰，同时还具有复杂核磁共振谱的编辑功能，能够在不做任何物理分离的条件下，分别研究生物大分子和小分子的扩散系数，以及分子之间的相互作用。

The change of average size of products along the radius at the exist of reactor has also been calculated. The calculated results indicate that the residence time is longer, the average size of products is larger, but the distribution of size is narrower, tending to self-preserving distribution; when the concentrations of reactants increase, the average size of products becomes larger, but the distribution of size becomes narrower; the gradients of reactants are greater, the average size is larger; the increasing of reacting temperature will cause the size of product to be larger under same residence time. The average size of product at the exist of reactor varies along the radius, has a maxim value.

模型计算结果表明，产物粒度随停留时间的增加而增大，但粒度分布变窄，趋向自保分布；产物粒度随反应物进料浓度的增加而增大，粒度分布随进料浓度的增大而减小；反应器中反应物浓度梯度较大（相当于化学反应为快反应）时，相同停留时间下所得到的产物平均粒度增加；反应温度的增加，粒子平均粒径增加，粒度分布变窄；反应器出口处粒子平均粒径，随着与对称轴的距离的增加，有一极大值，先增加，后减小。

In addition, water gradients, crack width, permeability time, specimens kinds can also influence the self-sealing degree.

This means that the cartoon is shaded with gradients and lighting effects to produce a 3D look and feel.

这意味着，漫画的阴影与梯度和灯光效果，以产生一个三维的外观。

It is concluded that m = 2 tearing mode is produced by the current gradient. Ifoptimized current gradients are retained in the vicinity of q = 2 singular surface, the disruption can be avoided. There is no need to select current density profile on the whole plasma section.

结果表明这种不稳定性由q=2奇异面附近电流梯度的增大引起，因此只要在奇异面附近保持适当的电流梯度就可避免破裂发生，即对电流分布实行局部控制就可实现对破裂的抑制，并不需要去选取某种特定的整体分布。
