ABSTRACT No matter whether it is a Science Experiment or an Engineering Test, it will be more or less effected by the environment, such as temperature, moisture, time, instrument and man-made factors. Thus, the test result does not include complete information, or the data obtained have errors. Sometimes even the data obtained are complete and correct, but they are not continuous values. Under a soil consolidation test, we might fail to record the data once. When the rocket is launched, we might have one signal missing. For all of such kind of omission, we can use a numerical approximate or a curve fitting method for this remedy. Interpolation is the most often used and the most effective method among the above mentions.
The interpolation methods in the classical numerical analysis are Newton Interpolation, Lagrange Interpolation, Aitken Interpolation and Hermite Interpolation, etc… All of these interpolation methods can be expressed by one polynomial. They can also be operated by computer according to Fortran IV or C Language. However, these polynomials are limited to single independent variable function, such as y = f(x). In fact, as mentioned above, many factors may affect the result of an experiment or a test, such as rocket launching, satellite positioning and the astronomy measuring which has a close relationship with the astronomical yearbook. To locate a planet from one point of the earth needs at least longitude and latitude two parameters. Therefore, if you want to use single independent variable interpolation to get the location of a planet or locations of thousand planets in a certain time or in a full year which cannot be found in the chart of galaxies, the calculation is not only complicated, but also take a very long time in all proceses. Even if we use a computer deal with it, this is almost an impossible mission.
As proverb says, “Impasse is followed by change, and change will lead to solution.”. When we make a scientific study, if one method is not workable, we need to change the direction of our thought. We cannot always depend on the original calculating method and the tools which we used before. Innovation creates breakthrough. Breakthrough creates success. In this study, I want to discuss a formula of multiple independent variable interpolation method which I discover based on this principle after a continuous research. This result of the research makes the past difficult task easy, and simplifies the past complicated calculation. It has saved a lot of time for the researchers, and also has saved a large amount of public treasury for my country through the past many years. Thus, this study not only breaks the bottleneck of Newton,s formula and also creates a new situation on the applied engineering.
