Based on long term study, we put forward new algorithm of recognizing fingerprint directional diagram: the iterative algorithm based on model, which revises the singular points (central point and triangulation point) and fingerprint directional diagram through local and global iteration. Hence, the algorithm can recognize the directional diagram and singular point more accurately and can extract detail features more accurately.

经过长期的研究，我们提出全新的判别指纹方向图算法：基于模型的迭代算法，通过局部和全局反复迭代修正图像的奇异点和指纹方向图，更能准确地判断指纹方向图、奇异点，从而更能准确地提取细节特征点。

It is better to use a neutron or proton rich projectile with atomic number notfar away from the expected exotic nuclei because the difference in the fragmentationcross section induced by neutron or proton rich and stable projectiles becomes smallwith the increase of the distance between the produced fragment and the projectile. Measurements of 〓 for 〓,〓 and 〓 at intermediate energieshave been performed on the Radioactive Ion Beam Line in Lanzhou.

所选的丰中子或丰质子炮弹最好离所需产生的丰中子或丰质子奇异核比较近，因为随着炮弹与产生的核的距离的增加，丰中子或丰质子炮弹与稳定的炮弹的碎裂反应产生奇异核的产生截面的差别变小。

If a certain springing lightness is the characteristic of Chenonceaux, if it bears in every line the aspect of a place of recreation – a place intended for delicate, chosen pleasures – nothing can confirm this expression better than the strange, unexpected movement with which, from behind, it carries itself across the ricer.

如果所舍农索的特色是一种春天般的轻盈飘逸，如果所舍农索的特色是一种春天般的轻盈飘逸，它的每根线条都显示出一个娱乐场所的样式——一个为细腻，精选的快乐准备的地方————一个为细腻——没有什么比那奇异而出人场所的样式——一个为细腻，精选的快乐准备的地方——没有什么比那奇异而出人意料的行为更能证明这种表现了：城堡的后面居然跨过了河流。

So it can be avoided that the computation accuracy is lowered and the calculation result is hard to be convergent for the odd state of transformation matrix.The computation accuracy of wavelet Ritz method and wavelet Galerkin method has been improved so the special'microscopic'property could be fully expressed. An effective method is offered also to solve the problem of high stress gradient and some other odd state problems in engineering.
