These samples were collected along a main street across the urban area and a mountain route from foot to the top. Results demonstrate that the main magnetic minerals in the street dust are magnetite, maghaemite and haematite with some paramagnetic minerals. Plots of Mrs/Ms vs. Bcr/Bc and Xfd % vs. X ARM/SIRM indicate that the main grain size of magnetic minerals in the street dust are pseudo single domain. The results reveal that the Lanzhou city is more polluted in spring than in summer. The main pollution sources are anthropogenic activities （81.9%） and natural dust （18.1%）, especially the former. The spatial distribution of pollution is controlled by the topography and weather conditions.

结果表明，兰州市街道尘埃中磁性矿物含量较高，主要磁性矿物是铁磁矿、磁赤铁矿和赤铁矿，并伴有少量顺磁性矿物；磁性矿物粒度主要是准单畴；市区污染春季较夏季严重，春季高频率的强沙尘暴可能带来了更多的磁性矿物；兰州市污染物的沉积和分布在很大程度上受到气象条件和地形地貌格局的影响，市区每个盆地东端高于其它地区；兰州市污染以人为活动产物为主，人为活动贡献约为81.9％，其中包含交通约22.6％的贡献，自然降尘贡献约为18.1％；特殊的地形和气象条件，使得兰州市区的大气环境容量比平原城市的环境容量小得多，进而导致严重的大气污染。

The pigment of Berberis heteropoda Schrenk is a type of anchocyanin and it is strong in resistance against light and to some extent, good in enduring heat and low consistence oxide. But it is poor in resistance against reductant and preservative. It can be applied to the condition of PH. It is also found that sucrose and most of metal ions do not exert negative effects on the stability of the pigment, except Fe3+, Fe2+and low consistence Pb2+, which have some extent effects. Adding stability matter can improve its stability. The harm trace elements contains are within requirement of the National Standard on food safety, As the lexicological study indicates that the pigment does not have any toxicity and mutagenesis, it can be used as edible pigment.

Methods: The experimental type Ⅱ diabetic rats were induced by injection of strepiozotocin (STZ, 30mg/kg ) and fed with high fat and high glucose fond. The rats were divided into three groups: a normal conrmal control group, a diabetes group and a treated group. The treated group were hypodermically injected insulin 3U/d at interfemus for 4 months, white DC and NC group were vehicle groups that were treated with the same close saline, By using SABC method, thee express ion of collagen type Ⅰ and Ⅲ in SAN was detected.

This model uses nonlinear mapping to map samples into high dimensional feature space, and compares the distribution of each type of samples in the high dimensional space. So that a binary decision tree is constructed through clustering, which can make the more separable classes classified at the upper node of the binary decision tree. The model overcomes the accumulation of misclassification and avoids the condition of impartibility efficiently. At the same time, each node of decision tree uses binary least squares wavelet support vector machine to obtain higher generalization ability.

该模型利用非线性映射将样本投影到高维特征空间，比较每类样本在高维空间的分布情况，进行聚类构造出一个二叉决策树，使容易区分的类别从根节点逐层分类出来，有效克服了错分积累和避免不可分情况；同时，各个节点采用二值最小二乘小波支持向量机，以获得较高的泛化能力。

Data pre-processing technologies such as singular points elimination, registration and radius compensation are studied. Base on chord high difference algorithm, a new one called chord high difference-ratio algorithm is proposed to improve veracity and robusticity of singular points elimination. Then, a registration algorithm based on local surface reconstruction is proposed, which avoids infaust influence coming from single reference point error.
