Deriving Improved Newton's Second Law and the Law of Gravity at One Time with Form of Fractal Formula

Fu Yuhua

Strategic Study of CAE 2003, Volume 5, Issue 6, Pages 55-58

Abstract:

Newton's second law and the law of gravity are summarized with experimental results.For discussing the possibility of deriving the two laws theoretically, according to the law of conservationof energy, the method of deriving improved Newton's second law and the law of gravity at one timeresults suitable for this example with the constant dimension fractal form are as follows： improved lawof gravity F = - GMm/r^1.99989 , and improved Newton's second law F = ma^1.01458

Thoughts on the Law of Automobile Industry Development

Fu Yuwu, Chen Xiumin

Strategic Study of CAE 2019, Volume 21, Issue 3, Pages 98-102 doi: 10.15302/J-SSCAE-2019.03.019

Abstract:

Automobile industry has accumulated numerous worldwide-accepted laws since its emergence over 130 years ago.China's automobile industry is currently facing a strategic opportunity for industrial transformation and upgrading, so it is necessary to strengthen the research on the laws of development for the automobile industry, thus to avoid any impulsive actions. In this paper, nine laws of development are summarized from the aspects of technology, market, and talent, including the complementary relationship between transformation and upgrading, the characteristics of the capital-, technology-, and labor-intensive industry, the inevitable requirements of innovation and collaboration, etc., thus to guide and promote the healthy and sustainable development of the automobile industry in China.
