Negative feedback control algorithm for nonlinear rolling motion of ships

In order to describe the nonlinear phenomena and to find the regularity of ship rolling motion, the mathematical model of ship nonlinear rolling motion is built. The Lyapunov exponent curve is used to judge the chaos phenomena of ship nonlinear rolling motion. The nonlinear method of the negative feedback control algorithm is employed to control the chaos phenomena and to obtain the appropriate range of the negative feedback coefficient k so that the nonlinear phenomena are mitigated. The results show that the method can achieve a satisfactory control effect.     

EFFECT OF EXERCISE ON THE ACTIVITY OF 5α-REDUCTASE IN THE CYTOSOL OF LIVER,KIDNEY AND PROSTATE

It has a different change in androgen in serum and some special tissue after exercise, and it is according to the sensate and time of exercise. It is necessary to study the metabolism of teststerrone in some tissue after exercise, This experiment is using the technology of thin chromatography to analyse the 5α-reductase in tissue and calculated the rate of T metabolism. Because of the activity of 5α-reducatase that is too low, that the activity of 5α-reducatase in muscle and brain has not been tested. The exercise could develop the activity of 5α-reducatase in liver, kidney and express the activity of 5α-reducatase in prostate.

英文摘要

Abstract： Requirements of distance education journals are analyzed from the perspective of writing paradigm, and results re- veal the stylistic features and adoption standards of these journals, which fall into two categories ： specialization and quality. The former refers to originality, substantiality and academic value of the paper. Therefore, topic is selected, focusing on individuality and innovation, that is to say, finding out the breakthrough point by exploring a novel perspective, while avoiding dialectic emp- tiness and generalization, as well as empirical studies of no realistic significance. The latter refers to the application and formation of writing paradigm, which is under the influence of academic standards. Scholarly journals should maintain their academic dignity in way of preciseness and standardization.     

Skills Availble for Improving Listening Comprehension

AS time goes by,the Grammar Transalation Method of teaching a foreign 1anguage is being elbowedout of the way.A more efficient,scientific and practical method is being adopted.That is theAudio-Lingual Method launched by the American linguistic L.Bloomfield.The kernel of thismethod is Stimulus—Response Training,that is the practice of listening and speaking.With the helpof recording and audio—tape,the students are guaranteed to learn the standard pronunciation andintonation and commit less errors of "Chinglish" for our Chinese.The students may achieve fluency     

Some Personal Comment About Behaviorist Approach

How an articulated mammal learns a foreign language has been a mystery for many years to language researchers. Language scholars have put forward different ways to explain this problem. Yet all of them are not perfect. Each of these theories has contributed both quantitively and qualitively to the different aspects of language learning. However, language learning and teaching doesn't happen in a vaccum. It is affected by many factors. In vast rural areas in China, practically speaking, behaviorist approach fits in with the writer's own experience. Some weaknesses of this approach are also discussed. Therefore what is important is to adapt, not to adopt blindly.
