On the Structure of "秀才秀才,错字布袋

Abstract: Sentence patterns like "秀才秀才,错字布袋"are unique in the grammatical structure, semantic structure and pragmatic function. The typical feature of this pattern is that the same word or phrase reappears continually at the very beginning. It has two parts: (1) The proceeding part("秀才秀才") includes a word and its repeated form, which is different from the reduplication in grammar and the continual repetition in rhetoric. This part can have referential functions in particular situations;and (2) The main function of the last part ("错字布袋")is to interpret the proceeding one. It is the semantic focus of the whole sentence. This sentence pattern typically shows the features of proverbs like "秀才秀才,错字布袋"in language structure,semantic meaning and pragmatic function.

Extractingra methods of associated rules based on granular binary operations

Abstract: This paper discusses the information granules and its real examples.A relation between granule and binary numeral is established.The similarity and transforming relation between granular computing and binary numeral operations are also defined.Hence,the decision making based on granular computing is transformed into the extracting associated rulas using binery operations.The speed of decision making is more rapid,efficiency is also higher.

Study in Process Parameter of Preparating Rheocasting Slurry by the Method of Cooling Slope Tube

Abstract: Fine near ball nondendritic grain of primary microstructure needed by semi-solid forming was obtained in Preparation of the Rheocasting Slurry by method of cooling slope tube of alloy ZL101.The influences of cooling slope tube,the pour temperature and the cooling speed were investigated.The results show that the cooling slope tube has effect of producing mass (crystals.)The low pour temperature is in favor of producing (crystals,)but pour temperature can't be too low;the microstructure on demand can't be obtained when the cooling speed is too quick or too slow.Fine near ball nondendritic grain of primary microstructure needs suitable cooling criterion.

Scale Digital Watermarking Algorithm Based on Two-dimensional Engineering Graphics

Abstract: A digital watermarking scheme is presented according to the characteristics of two-dimensional engineering graphicsWatermarking information is embedded by modifying the scale of the distance between vertexes in two-dimensional engineering graphicsIf the visual effect is the same,this scale will not be changed because it is a whole characteristicThis scheme is very robust against the attack such as rotation,translation,scale and so on,which is illustrated by the result of the experiment

PLJERC-FDTD Analysis of Wide Band Scattering for Perfectly Conducting Cylinder Coated with Non-uniform Plasma

Abstract: A novel FDTD formulation for dispersive media,which has high accuracy and efficiency,called piecewise linear current density recursive convolution (PLCDRC) finite different time domain (FDTD) method is applied to the electromagnetic scattering of perfectly conducting cylinder coated with non-uniform plasma in this paper.By simulating the interaction of electromagnetic wave with unmagnetized plasma,some bistatic and wide band numerical results are obtained,which indicate that plasma cloaking can greatly reduce the back wave energy of radar targets.

Combination of Orthogonal Experimental Method,Neural Networks and Genetic Algorithms

Abstract: It is an efficient method to solve engineering optimization problems with neural networks and genetic algorithms.Because of many defects in themselves,the applications of neural networks and genetic algorithms are restricted and it's almost impossible to use them in complicated fields.Orthogonal experimental method is a scientific experimental method of many factors.This paper introduces this method,combined with neural networks and genetic algorithms.In this way we overcome their respective defects to some degree and broaden their applications.

Establishing a Learning Society and Developing Adult Education

Abstract: Establishing a learning society is an important goal of building the well-to-do society . In order to establish a learning society, we must develop the continuing education and construct the lifelong education system. The adult education is a part of the system of the continuing education and the lifelong education. The functions of the adult education in establishing a learning society are perfecting the education system of the whole people's study and the lifelong study, accelerating the process of establishing a learning society of the whole people's study and lifelong study and promoting the level of the whole people's study and lifelong study. In order to establish a learning society of the whole people's study and lifelong study, we should enrich the content of the adult education, widen the channel of running adult education schools and develop the modern long-distance education.

Analysis of Doctor's "Moral Venture

Abstract: There are some different features between the medicine market and the general commodity market.Especially,doctor has complete information but patient has incomplete information;patient can control and react to doctor's cheat by repeated games and signaling game in some degree, and we can too take some countermeasures to avoid doctor's "moral venture",such as strengthening the punishment and setting up some trust mechanisms.

Patterns and Prospects of Professional Title Evaluation

Abstract: For a long time in China,a pattern in the practice of personnel and professional title departments as the leading part has existed.In recent years,the pattern to separate evaluation and appointment has been further into use and the pattern to evaluate and appoint by a unit itself has been spread.All the three patterns have their advantages and disadvantages.The coexistence of all the above-mentioned patterns is the reform trend,on the condition that an intermediary organization be established and the government role be actively put into play in the reform of professional title reform.

Study on Bubbleless Aerated Membrane Bioreactor for Domestic Sewerage Treatment

Abstract: The study on treating domestic sewerage by bubbleless aerated inorganic ceramic membrane bioreactor was conducted.The bubble point of oxygen in the membrane bioreactor system was measured before and after the formation of the biofilm.The properties of the film forming of the biofilm are studied.The effects of the flux and the pollutant concentration (COD) of inlet on COD removal are discussed respectively.The COD removal is more than 90% when the flux of inlet is 15.75 L/(m2·h) and the pollutant concentration is 200 mg/L.The COD concentration of outlet is lower than the domestic station service water quality standard CJ25.1-89 issued by the Construction Military of China.Comparing to the traditional bubble aerated membrane bioreactor,the bubbleless aerated membrane bioreactor has many advantages,such as faster oxygen transferring rate,higher oxygen uptaking rate (100%),lower energy consumption,smaller equipment size and lower noise.
