次氯酸钠对隐孢子虫卵囊在体外脱囊的影响

中国人兽共患病杂志 1998年第5期14卷 53-55页

作者：张健騑杨世广 MarkC.Healey 广东农科院兽医研究所广州五山510640 美国犹他州立大学

隐孢子虫卵囊的无菌化及体外脱囊是进行虫体体外细胞培养不可缺少的环节，本试验通过使用不同浓度次氯酸钠提前处理卵囊，在不同脱囊液的条件下比较各处理组的脱囊率。试验结果表明，未经任何处理的卵囊，在37C的温度下可发生脱囊，但... 详细信息

隐孢子虫卵囊的无菌化及体外脱囊是进行虫体体外细胞培养不可缺少的环节，本试验通过使用不同浓度次氯酸钠提前处理卵囊，在不同脱囊液的条件下比较各处理组的脱囊率。试验结果表明，未经任何处理的卵囊，在37C的温度下可发生脱囊，但脱囊率只有15．5％（脱囊时间90min）；经100％bleach（含5．25％次氨酸钠）作用30min，对卵囊的活性有很大的影响，在T＋TDC（Trypsin＋taurodeoxycholicacid）脱囊液中，其脱囊率只有17％（约正常卵囊的20％）；5％～20％的bleach对卵囊的活性没有明显的影响，反而有很强的刺激脱囊作用，卵囊经这一浓度范围的bleach处理后．即使没有酶的存在，其脱囊率也可达到80％以上。单独使用酶或bleach均有很好的脱囊作用，但两者合并使用，并不能提高新鲜卵囊的脱囊率。对用于细胞培养的卵囊，推荐用10％～20％bleach处理30min，这一处理，既可得到无菌化的卵囊，又有高的脱囊率。

Contour motion control is one of the important topics in motion control research,which has been widely applied in motion control tasks in manufacturing and other automation *** effort,such as cross-coupled control(CCC),has recently focused on improving contouring ***,it is remarkable to see the increasing number of studies related to the theory and application of fractional order controller(FOC),especially PIDcontroller, in many areas of science and *** this paper,a new ITAE criteria optimal design method of integer order PID and fractional order PID controller is proposed for cross-coupled contour motion system which is based on contour error estimation algorithm and contouring error transfer function(CETF).Simulation results show that the proposed algorithms are effective,and fair comparisons illustrate that fractional order controller can achieve better performance than integer order controller.

異位前列腺罕見,是指在前列腺正常部位以外發現的前列腺組織。我們診治膀胱異位前列腺1例,現報告如下。患者男性,69歲,因排尿困難1天門診就診。查尿常規正常。行超聲檢查示:膀胱後壁見一向膀胱腔內隆起的橢圓形等回聲結節,邊緣光滑,回聲不均,與前列腺分界較清,考慮膀胱佔位病變。再行CT檢查示:膀胱三角區一大小1.5×1.3×1.0cm類園形結節向腔內突出,CT值約46HU,增強掃描後腫塊呈不均勻強化,延時8分鐘後該結節區呈充盈缺損,顯示清楚,考慮膀胱內佔位。

Fast velocity analysis by wave path migration

中国科学院地质与地球物理研究所第十届(2010年度)学术年会

Iterative migration velocity analysis is computationally expensive,where most of the computation time is used for generating prestack depth *** using a reduced form of Kirchhoff migration,denoted as wave path migration,we can significantly speed up the depth imaging process and reduce the entire velocity analysis expense *** results with 2D synthetic and field data show that wave path migration velocity analysis can efficiently improve the velocity model and the wave path migration velocity analysis updated velocity correlates well with that from the Kirchhoff migration velocity *** central processing unit comparison shows that,for a 2D synthetic and field data set,wave path migration velocity analysis is six times faster than Kirchhoff migration velocity *** efficiency should be even greater for 3D data.

Robust Fractional Order Differentiator

第24届中国控制与决策会议

作者： Dali Chen, YangQuan Chen, Dingyu Xue College of Information Science and Engineering, Northeastern University, Shenyang, 110004, China 2.Center for Self-Organizing and Intelligent Systems (CSOIS), Department of Electrical and Computer Engineering, utah State University, Logan, ut 84322-4160 USA 3.College of Information Science and Engineering, Northeastern University, Shenyang, 110004, China

A robust fractional order differentiator is proposed to estimate the fractional order derivative of the given contaminated signal. Least square polynomial fitting technique is used to minimize the noise and Griinwald-Letnikov definition is used to calculate the fractional order derivative. A concise method is proposed to speed up the computation time and a parameter setting strategy is present for user. The frequency domain analysis demonstrates that the proposed differentiator essentially is a fractional order low-pass filter. The accuracy and robustness are evaluated by the experiments.

In this paper, an adaptive image enhancement based on fractional differential mask is proposed. Firstly, the designing method of the fractional differential mask is introduced and the image enhancing strategy based on the fractional differential mask is presented. Then, an unsupervised method is introduced to optimize the fractional order parameter by using the statistical character of digital image. The experiments demonstrate the validity of the proposed image enhancing algorithm.
