In the synthetic procedure to chiral docetaxel C13 side chain, the expensive cinchona alkaloid derivatives can be recycled, which dramatically decreased the reaction cost.

在多烯紫杉醇手性C13侧链的合成过程中，对价格昂贵的金鸡纳生物碱衍生物配体进行了回收和再利用，大大降低了反应成本。

Firstly, the establishment of model requires sophisticated neurointerventional techniques and costly interventional materials(sacculus, minikin circlip ring, endovascular electrocoagulation), it not only consumed time but also increased the resesrch expense ; Secondly, although the Massoud model is the first successful model that contain the nidus, but it is far from mimicking the high-flow fistulae frequently observed in a brain AVM; Thirdly, the rapid spontaneous thrombosis result in fistula occlusion in a short time;Fouthly, the model's natural course and the long–term patency of fistula are unclear;Currently the model is only used for the short-term research.

但Massoud模型目前存在以下主要缺点：第一，模型的建立需要复杂的神经介入技术和昂贵的介入材料(球囊、微弹簧圈、血管内电凝等)，操作费时，又大大增加了研究费用；第二，Massoud模型虽然首次具备了畸形血管团，但它远不是我们临床上常见的含有高流量动静脉瘘的脑AVM；第三，颈动静脉吻合口自发性血栓形成进而导致引流静脉闭塞的机率很高；第四，Massoud模型的长期自然过程和动静脉吻合口的长期通畅性尚不清楚，目前仅仅作为急性期模型。

The principle and design scheme is set forth about antenna tracking control system of orbit weather secondary planet in the paper. Its characteristic is that the circuity of the system is greatly simplified by tracking logic circuit, The well effect is shown in practice.

This shift shall greatly benefit earth and mankind alike as many of such entities sit in a density of the old consensus thought-form, which is black, brown, gray, mucous yellow and green in color if viewed clairvoyantly.

这个变化会大大有助于地球和人类，因为很多这样的存有们坐落在旧一致实相致密的思想形态中，如果透视他们的话，是黑色、褐色、灰色、粘黄和粘绿的色彩。

But under limited training sample size, increased dimension of remote sensing data means decreased samples/dimension ratio, which can lead to low classification accuracy if common statistic based pattern classification methods were used.

但在有限训练样本条件下，遥感数据维数的增高使样本/维数比率大大降低，采用常规的统计模式识别方法反而无法得到较好的分类结果。

Using the diagnosis method of IEUNIM, the initial multi-weights are gained by classifying the space of fault character and the identification of network is improved greatly by using K-means Clustering.
