查询词典 asymptotic curve

A sandwich ELISA was established taking the antiserum as the primary antibody. The sensitivity of the ELISA was 0.412 ng GH/ml of sample. Inter-assay and intro-assay coefficients of variation were 2. 58％(n=6) and 5. 69％(n=6) respectively. Serial dilutions of serum and pituitary homogenate from orange-spotted grouper yielded dose response curves that were parallel to the standard curve. And the GH of Acanthopagrus butcheri was also parallel to the standard curve. Prolactin of goldfish and recombinant growth hormone of common carp showed no cross-reactivity with the antiserum of orange-spotted grouper GH. It showed that the established RIA was specific and sensitive.

以斜带石斑鱼重组GH抗血清为第一抗体，羊抗兔抗体为第二抗体建立了双抗体夹心酶联免疫测定法，该系统的灵敏度为0.412ng GH／ml(n=6)，组内变异系数为2.58％(n=6)，组间变异系数为5.69％(n=6)，斜带石斑鱼血清和脑垂体稀释液曲线与斜带石斑鱼重组GH蛋白的标准曲线相平行、黑棘鲷GH的系列稀释曲线与标准曲线相平行，金鱼催乳素、重组鲤鱼GH的系列稀释曲线与标准曲线不平行，表明建立的斜带石斑鱼GH ELISA具有良好的特异性和重复性，灵敏度达到了测试血清样品中GH的水平。

So this paper selects national debts as our studying objects. By using principal component analysis method to study the zero coupon yield curve, we find that the movement of the curve yield can be simulated by two factors mostly, that is parallel shift and rotation. Then we quantitative them and get "synthetic parallel shift" and "synthetic rotation".

因而，本文选择了国债作为研究对象，对国债的即期收益率曲线进行主成分分析的结果表明，收益率曲线变动的总体方差绝大部分来自于两个因子的贡献，即水平因子和倾斜因子，本文对这两个因子进行量化处理，得到"综合的平移"和"综合的倾斜"，并在此基础上建立了两综合因子法对债券组合的VaR估值模型。

Such "curve" risk can arise in portfolios in which long and short positions of differ-ent maturities are effectively hedged against a parallel shift in yields but not a-gainst a change in the shape of the yield curve.

这种利率曲线风险将产生在长、短部位到期期限不同的组合中，虽可有效规避殖利率平行移动的风险，但却无法规避殖利率斜率改变的风险。

Space curve is one of the basic elements in geometric modeling, and its effective representation is the basis of modeling. Parametric representation based on features is a kind of high-level representation including semantic information. In Chapter 4, para- metric representations based on features for free form space curve are investigated, and a parametric model for the loop of plain knitted fabric is established, in which 5 parameters with practical meanings are used to represent the shape of a loop and the relationship between loops. A new shrinkage prediction method for knitted fabric are proposed based on the parametric representation and energy minimizing. Experimental results on some plain knitted fabrics illustrate the feasibility of the proposed method.

空间曲线是造型中最基本的几何元素之一，对其有效的表示是造型的基础，而特征参数化表示是其中一种包含语义信息的高层次表示，本文对空间自由曲线的特征参数化表示进行研究，建立了一种针织物线圈的特征参数化几何模型，采用5个具有实际意义的参数表示织物线圈的几何形状及线圈之间的位置关系，并将该模型与能量极小化的方法相结合，得到了一种能较好地预测针织物缩水率的新模型，对随机选取的一些针织布缩水预测实验表明了算法的可行性。
