By Downloading the data from SinoMed by querying and applying the data slicing algorithm on associated keywords,the rules of ankylosing spondylitis are explored and illustrated through 1 dimensional explanation and two dimensional network diagram,In TCM syndrome on ankylosing spondylitis,it is focused on kidney yin deficiency and dual yin deficiency of liver and kidney.As for treatment principle,it is focused on warmly tonifying,freeing the collateral vessels,and resolving stasis.Through text mining,together with the manually anti-noising,the rules of Li-Fa-Fang-Yao can be explored for disease ankylosing spondylitis which can be used as a reference for both clinical practice and scientific research.
By using FEM analysis,a finite element model for frame of the four-wheel farm transporter based on 3D plate element was established.Through changing the thinckness of the four-wheel farm,the staic load and braking working condition were analyzed.Modal analysis was done for the frame,the improved scheme was put forward and the reference for remodel design was provided.
Non-verbal communication,as a means of communication which is used to convey some specific information and communicate with foreigners in specific cultures,plays an irreplaceable part in human communication.This paper begins with the definition and its different types of non-verbal communication,and discusses the cultural differences of non-verbal communication in the cross-culture communication.At the same time,suggestions are given to improve students’ cross-cultural communicative competence in college English teaching.
The temperature control instrument with the semiconductor refrigeration is studied in this paper.It has a lot of advantages,such as small size,light weight,high sensitivity,no refrigerant and no pollution.According to the physical characteristics of the semiconductor refrigeration technology,a drive circuit of TEC is designed by PI control method,which makes full use of the characteristics for refrigerating and heating quickly.
The multimedia synchronization of Abstract and description is the premise of distributed multimedia,the realization of this kind of synchronization needs the help of the time model and formal description tools.Based on research of the media timing relations and multimedia synchronous dynamic characteristics,and with the help of Petri net,a multimedia synchronization model to adapt to the development of network technology has been proposed
With the rapid economic development,the social demand for the English translators is higher and higher.As a part of English learning,mastering the methods and techniques of translation for the English learners is very important.This paper analyzes the English translation techniques from the aspect of vocabulary,long sentences and passive voices,etc.It turns out the good command of these translation techniques is helpful to understand the languaqe and the precise of the translation.
In ancient China from Western Han Dynasty to Qing Dynasty,the royal family had a 2000 years history to make peace with rulers of minority nationalities in the border areas by marriage.Because of the marriage concept in Song Dynasty.there was no such a case in Song Dynasty and Ming Dynasty.It’s affected by national self-reliance orthodox view of central plains of China,highly developed social economy,the policy of protecting intern and ignoring extern and neo-confucianism in the bud and thriving in Song Dysnasty.
Total station instrument is the main method in the positioning of civil engineering construction.According to the different conditions of construction sites,the different requirements to the measurement accuracy,the effective operation between total station and the prism and the layout positioning method and skills are discussed.
By using the differential definition and the definition of definite integral,a method to prove Newton-Leibniz formula is given,and image geometry is explained with the method.This proof reveals internal relations between differential and definite integral.
Zheng Yuanjie,a writer of children literature,has explored a new way of writing,which is different form his early fairy tales after he turned to write for adults.The thesis aims to study the aesthetic quality of Mr.Zheng’s adult fairy tales from the perspectives of narrative methods and points of view as well as the features of language.
