英语翻译说明如何绘制实验曲线实验数据用图形表示的优点是直观清晰，便于比较，容易看出数据中的极值点、转

Explain how to draw the experimental curves.The advantage of using figure to expression experimental data is clearly,easy to compare,and easy to see the extreme value point and turning point,periodic rate and other properties in the data.The first step in experimental data sorting is tabulation.When tabulating we should make clear the relevance between the data,and know what is independent variable,what is dependent variable.When the date we needed cannot be searched out from chart,we can use interpolation method,linear interpolation method is the simplest.We should be careful to use extrapolation method.Voluntaryly extrapolating can be unreliable if we don't master the law for data changing.The second step is to build coordinate system.Abscissa (x) expression independent variable,ordinate (y) expression dependent variable.Origin of coordinates may not be zero,it depends on particular case.Coordinates indexing should conform to the effective number of the experiment data,namely the effective digital readouts coordinates of the experimental curves should be identical with the digit of experimental data.After considering above,the figure could express correctly functional relation between x and y.The third step is marking the date of the chart to corresponding coordinate system.When connecting each discrete point into smooth curve,we should get through more experimental point as far as possible,or make the point outside close to the curve and equalize the number of points on both sides of curve.In order to assess the quality of the curve,we should calculate mean-square error of experimental data,the smaller,the higher quality of the curve.累死我了,查了好久...不是2楼的机器翻译,觉得可以的话请采纳,======以下答案可供参考======供参考答案1:explain how to draw the empirical curve describe how to draw the empirical curve供参考答案2:Experimental data using graph is clearly, facilitate comparison, easy to see in the data extreme value point and turning point, periodic rate and other properties.The first step in sorting of experimental data, the work is should be clear tabulation tabulation of correlation between data, which is independent, which is the dependent variable. When the data from the table to not found in May, when using interpolation method, interpolation method in the most simple linear interpolation method is. Use extrapolation carefully, if not when the master data of variation and optional extrapolation is not reliable.The second step is to build HengZuoBiao x, y, said that argument, including different origin as dependent variable, depending on the specific circumstances of zero. Coordinates points should be well with the experimental da
