 Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103207 Abstract: This paper is different from the existing macroeconomic theory. It derives the relationship between the various macroeconomic variables from the Cobb-Douglas function, and uses statistical data in United States to verify these equations. We find that the Cobb-Douglas function is obtained in the case that the marginal output is not 0, therefore it is a function with dynamic properties. On this basis, we use the difference between the compound output and simple output to determine the incremental output of a period, and its relationship with capital, interest rate, investment and other variables. These relations not only deny the premise of Keynesian theory, but also because the proof of the investment is not equal to the incremental capital, leaving the investment, output growth, business cycle and other neoclassical theory crisis.
 Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103215 Abstract: The Cobb-Douglas function not only leads to a long-term relationship between the rate of output change and the interest rate, but also analyzes why they fluctuate in the short-term. This paper first divides the fluctuation cycle of the interest rate in the statistical data of the past 45 years by using the mathematical phase diagram method, and draws the phase diagram of the rate of output change on the interest rate according to the cycle equation of output. From this phase diagram, we explain the reason that the phase difference between the interest rate and the rate of output change in the fluctuation. Then, according to the optimal relation between L and K in the Cobb-Douglas function, we further derive the employment equation and its relation to the real interest rate and the rate of real output change, and verify the theoretical speculation with statistical data. Finally, it is concluded that the business cycle is a kind of endogenous production phenomenon.
 Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103333 Abstract: The difficulty of inflation theory is to explain the fluctuations of the price level in short-term. First, we use the relationship between price and money in the traditional quantity equation to derive the inflation equation that can explain changes of the price level in the long-term and short-term. Then, by analyzing the phase diagram of the single variable and the complex variable in the inflation equation, we find that the fundamental reason of the periodic change of the short-term price is the periodic change of the real interest rate. Because fluctuations of the inflation rate and interest rate are the same in phase, so there is no difference in the business cycle. Finally, this paper analyzes the rise and fall of core price under the influence of money and real interest rate respectively. It lays the foundation for further discussion of the relationship between inflation and unemployment in Phillips curve.
 Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103525 Abstract: Traditional macroeconomic theory is difficult to analyze the long-term growth and short-term decisions of output in a unified model. In this paper, the concept of “unit resource output” is proposed by using the difference of production factors combination on different rays in Cobb-Douglas function, and its maximization condition is derived according to algebraic principle. And then we use this condition to explain the reason why the distribution parameter α in the Cobb-Douglas function is growing continuously in the US statistical data and predict the evolution path of the factor combination in the growth of the output. Finally, this paper compares the important differences between our model and the Solow model.
 Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103589 Abstract: In traditional macroeconomics argues that the decision and fluctuation of output level is short-term theory, and the growth of output is a long-term theory. The former is determined by the demand; the latter is determined by the production. No one has questioned why the former is determined by production and the latter is determined by demand. This paper argues that the factors that affect the output are the same in the short and long term, but there is no need to analyze the problem of fluctuation in the long term. Based on the analysis of the growth path in our previous paper, this paper first examines whether our model is applicable to the Pontryagin maximum principle, and then analyzes the difference of the Cobb-Douglas function in the exogenous growth model and the endogenous growth model. Reveal the special role of parameter A in Cobb-Douglas function: as long as A is considered as output-related variables, there is no substantial difference between the so-called exogenous model and endogenous mode. Finally, according to the trend of the growth path and the nature of A, the paper derives the final state of Cobb-Douglas function.
 Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1105084 Abstract: There are two reasons for the financial crisis. One is the spontaneous specula-tion in the capital market. The P/E ratio of the speculative object is much high-er than the ratio of capital to output in the factual economic system. The other is the crisis triggered by the bubble environment. In addition, inflation has a strong inhibitory effect on asset bubbles, and high inflation and asset bubbles will not occur at the same time. These can be verified by statistical data and theoretical explanation from the marginal state equation of Cobb-Douglas function.

 中国物理快报 , 2008, Abstract: We calculate the reflection probability for ultracold alkali atoms incident on a solid surface. By considering the interatomic interaction and using the WKB method, it is shown that the repulsive interaction between atoms has the effect of increasing the reflection probability. The increasing amplitude is related with the interatomic interaction and the depth of atom-surface potential. In addition, we also perform a numerical calculation to testify the effect of the interatomic interaction, and the analytic result is proven by the numerical result.
 浙江大学学报(人文社会科学版) , 2002, Abstract: An index system can be constructed according to Shaw's criterion to measure the degree of one country 's financial depth. The level of China's financial development can be assessed with this system while analyzing through the co integration test the equilibrium relationship among the representative variables of various index types. The results indicate that there are both identical and different aspects between the hypothesis and the features presented by China's financial depth. Moreover, its financial depth agenda is possibly less coordinated.
 Information Technology Journal , 2011, Abstract: There are special requirements on image processing in speed and robustness for vision based mobile robot navigation. But mobile robot captured scene color image’s processing has a high computational complexity and low robustness. To reduce data volume and improve robustness, a novel preprocessing method on color image for mobile robot navigation based on principle of threshold segmentation in HSV color space is proposed. Firstly, color image changed from GRB to HSV. Thinking of H component is instable when saturation level is too low, so the principle for single threshold gray image segmentation be used to choose a threshold T on S and divide S into high saturation and low saturation region, we can use H as segmentation basis in high saturation region and V in low saturation region. Then project H component to high saturation region and V component to low saturation region, H and V is stretched to different scope after projection. So, the S component contains not only color information but also gray information and reduces color image from three-dimentions to two-dimentions. Experimental results show that this method has more significant effects in improving the processing speed and robustness of illumination variation and shadows.
