The Wealth of Nations changed our understanding of the economic world just as Newton's Principia changed our understanding of the physical world and Darwin's Origin of Species.

国富论改变了我们对经济世界的理解，就像牛顿定律改变了我们对物理时间的理解，达尔文改变了我们对生活进化的理解。

Some people consider this as the most influential article in the three hundred years since Newton's "Principia Mathematica."

有人说这是三百年来物理学史上继牛顿的《数学原理》以后影响最深远的一篇文章。

The concept matured and was refined in Newton's mind over a period of years, and it was finally written in 1687 in his "Principia"(The Mathematical Principles of Natural Knowledge).

这个概念在牛顿的思想中酝酿和提炼了多年，最终于1687年写进了他的《基本原理》一书中。

In order to do research on pipe flow and pump characteristics of polymer flooding and water flooding rod-pumped well in especially high water-cut stage, rheometric test aimed at production stream from polymer flooding and water flooding rod-pumped well in especially high water-cut stage has been made, and the characteristic of production stream in especially high water-cut stage is confirmed as Newtonian fluid. Experiments using different mediums about pipe flow and pump characteristics is made. Frictional resistance and coefficient of friction resistance of annulus fluid between sucker rod and the pipe flow is calculated under different working conditions. Frictional resistance between plunger and pump barrel under different parameters is calculated based on related theory of pump characteristic and the strained analytical model of oil-well pump. Besides, using the theory of slit flow and hydraulic -clamping pressure, the frictional resistance is calculated, and the error between the result and measured value is no more than 13%.

This procedure is suitable for liquids with non-Newtonian behavior, i.e., liquids that are either shear-thinning or thixotropic.

此过程是合适于非牛顿体的液体。液体是可以剪切稀或触变型的。

But if that does not work, use some simple methods: part is a with corn flour of 喷粉器, and went to a place away from the scanner, the squeeze from 喷粉器 for the dispersalof from the air, when the high granula powder down, and they took transmissional draft of the piece, let it pass through spraying area, so that the fine powder particles in the air to it, in order to achieve the objective of the Elimination of Newton's rings.

但如果还来活命，那么不离给搁置一些单一的办法：局部是用装有玉米粉的喷粉器，行到挨近扫描仪的不天方，不兵玉米粉从喷粉器洋挤不入来，让它从空洋拆散，当不小颗粒的粉粒落下后，拿住透射稿的一角，让它穿过喷粉不天区，这样，空洋的粗粉粒不离落在其上了，以到达打消牛顿环的纲的。

Newton's first two laws hold only when observed in unaccelerated reference frames.

牛顿第一、第二定律只有在非加速的参照系中作观察时才是成立的。

Based on the theories of rheology, Non-Newtonian Fluid Mechanics, petroleum chemistry, crystallography and pipeline technology etc. and sampling Huabei crudes, experimental indexes and programmes are drew out, integrating the oil properties and parameter analysis; in terms of the macro analysis of continuum mechanics, substantial experiments are conducted with HAAKE RS600 rotational rheometer and the rheological equation as well as the viscosity-temperature equation are further developed with tested rhrogramme and viscosity-temperature curve, respectively. Beased on the researches on thixotropic mechanism and thixotropy fluid property, hysteresis loop curve, structure failure and viscosity build-up curve as well as shear stress decrement curve for one type oil are first present in this paper. According to the theoretical researches and testing results, a novel thixotropy equation with τ=τ_∞e~ pattern, which is of hi-accuracy, few parameter and simplicity, is developed. Considering the influence of various parameters on rheological behaviour, depressant adding condition is optimized and experimental evaluation on BEM-5P is conducted, which further unrip its mechanism on the Huabei crude. A corresponding viable pipe transportion programmel is also recommended.
