采用基因芯片的方法，将完全未甲基化的DNA和完全甲基化的DNA混合后制成标准曲线，将U266细胞株样本处理后点在芯片上与标准曲线进行比较后得出定量检测的结果。

Any given oil well has a finite supply of oil, and the wells' production follows the shape of a bell curve. Extracting oil is cheap and easy on the curve's upslope but after the the well has peaked – the point at which half of the well's oil has been extracted – production becomes more difficult and expensive. The output of the well begins to decline and will never recover; production falls steadily and the cost to extract the oil rises.

由於任何一个油井都只有固定的供应量，因此每个油井的原油产量都会遵循钟型曲线：一开始汲取原油很便宜也很容易，因此曲线是上升的，但当油井的产量到顶之后–也就是油井中的原油存量已被汲取出一半时–原油的生产就会变得愈渐困难且昂贵，油井的输出产量也开始下降，而且再也无法恢复，所以产量也将持续减少、使得生产成本不断增加。

It's a curve, but its a nasty, wiggly line that looks more like the trail of a worm on LSD than it does like any curve worthy of the name.

它是一条曲线，但它是一条没有固定模式的，波动的线，就好像吃了迷幻药的虫子的尾巴一样的曲线，而不是任何一条已经知名的曲线。

One is to understand the Spectral Characteristic Curve; the other is to satisfy the conditions of similar analogy, which means that the spectral characteristics are similar between the studied area and the area for collecting standard spectral curve as well as the area for analogizing.

The loading method and the quantity of linker had greater effect on in-vitro release curve. Release curve of incubation-absorption and entrapping method had two phases—quick release phase and slow release phase. And the first phase lasted about one hour and released 70% drug.

载药方法和交联剂用量对释药曲线有显著影响，吸附法和包埋法制备的载药DSMs的释药曲线明显分为快速释药阶段和缓慢释药阶段，第一阶段持续约1 h，释放药物的70%左右。

The program compile with BASIC language and O'NILLs filter coefficient can be used for forward calculation with the gived model.with the input of the observed data and the assumeed model,one can obtain the observed curve and calcula- ted curve in the Same dual logarithm coordinate.

该程序是根据 ONILL 的滤波系数，利用BASIC 语言编制的。它根据给定的地层模型可作正演计算。输入野外观测值以及所假设的地层模型便可在同一个双对数座标中绘出观测曲线和计算的曲线。

The surface roughness of the laser shock peened medium has effect on the high frequency of laser-generated surface acoustic waves. As the impact times of the laser shock peening increase, the surface roughness has little effect on the dispersion of laser-generated surface acoustic waves. From the theoretical curve and experiment curve, it can ...

The shortcoming of determining failure distribution in intuition is pointed out, and an idea of quantitating similarity between theoretic curve and testing curve to determine the failure distribution of samples is presented, which is based on analyzing the traditional leaf-figure method. Furthermore, the correlation coefficient method is considered to quantitate similarity between two curves.

在分析传统树叶图方法的基础上，指明了直观判断失效分布的弊端，提出了用量化理论曲线和试验曲线间相似度的方法来确定样本失效分布的思想，进而考虑用相关系数方法来量化曲线间的相似度。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
