交替性

If your going to try the cross-hatch style of quick shading, might I suggest that you further alternate and think about your angles a bit more (going 90 degress and making a checkboard pattern is kind of flat to me), it can be pretty powerful and descriptive if you stroke in the direction the form flows...might need to make your lines closer together so its more consistent.

如果你打算用交叉的平行线画出阴影，我建议你更多的交替线条而且角度多一点（90度递减还有画的格子图案对我来说跟平的一样），如果你每一笔的描绘都形成流动性方向，它可能会变的更有力度和描绘性，也许会让你的线条更紧密而且更连贯。

To variational inequalities with separate structures, the thesis presents a descend method based on the alternating directions method, and some numerical results demonstrate that the new method is effective in practice.

Cyclothymic Disorder involves alternating hypomania and depressive episodes. Like bipolar, cyclothymia involves cycling between highs and lows, but it never reaches full mania or major depression. It was previously called cycloid personality. Over a lifetime, the chances of having Cyclothymic Disorder are from 0.4% to 1%.

轻度躁郁症包含交替的躁跟郁的症状，跟躁郁症一样，轻度躁郁症包含躁跟郁的循环，但是未达躁症和重度忧郁症的程度以往叫做循环性人格终生发病的机率是 0.4% to 1%。

By iteratively combining these two procedures we achieve a way of training the configuration of RBFNN. In addition, the algorithm is very robust with respect to the noise level. Simulation experiments show that the proposed algorithms are sound. In chapter 3, which is the extension of chapter 2, the improvements of the architectures of RBFNNs and the solutions of their relating problems are discussed, Firstly, an new distance metric is advanced and a forward orthogonal least square selection procedure is applied to learning the parameters of classification function and selecting the important input nodes.

首先分析了目前存在的同时确定RBFNN结构和参数的方法的缺陷，在此基础上提出了用基于拉马克的进化学说的进化编程算法来改进算法，以克服某些缺陷；然后针对受到严重噪声污染的系统，如何提高RBFNN的泛化能力的问题，利用基于AIC的适应度函数的改进遗传算法学习结构和参数；最后介绍基于MDL原理的方法，将优化网络的结构和参数分为两个阶段：训练和进化，先自适应地改变RBFNN基函数的中心和宽度，同时训练输出线性权值，再用基于MDL原理的适应度函数的标准GA来优化隐层节点，通过交替使用这两过程达到训练RBFNN的结构和参数的目的，该算法具有较强的鲁棒性。

The basic view of the model that the intense subduction of the Indian plate beneath tbe Eurasian plate would result in inhomogeneity of the fabric and deformation of the lithosphere and repeated alternations of normal transformation from collision to contraction to stretching and reverse transformation from stretching to contraction.

其基本观点是强调由于印度板块向欧亚板块的强烈俯冲造成岩石圈组构和变形的不均一性及岩石圈中存在的碰撞→收缩→伸展的正向转变和由伸展→收缩的逆向转变的反复交替。

It has also been discovered that, before complete purification, the synthetic HWTX-Ⅰ, after oxidative treatment, showed wider and more asymmetric peaks than the native HWTX-Ⅰ that was denatured and then renatured under the same experimental conditions, which suggests that there is even greater conformational unhomogeneity in the synthetic HWTX-Ⅰ.
