Abstract: This article gives a contrast of molecular imprinting affinity purification method (by HPLC) and immunoaffinity column purification method (by HPLC) in the determination of zearalenone in corn. In the determination process, two levels (dosages) of 60μg/kg and 500μg/kg were used. Recoveries of by means of the two methods were 90.4%, 90.1% and 92.9%, 90.7% respectively. And the molecular imprinting affinity column can be reused several times.

Abstract: We have done some simulate analysis on GPS data in this paper. The main research is method of determining satellite clock error by usining observation data of satellite-ground and inter-satellite under the condition of regional station arrangement. The research method is as follows: when the satellite in the visible area of regional observation network, we can get satellite clock error directly by satellite-ground time comparison, and predict the satellite clock error in invisible area. When the satellite in the invisible area of regional observation network, if this satellite can establish inter-satellite links with other satellites in the visible area, then the satellite clock error can be determined by time comparison of satellite-ground and inter-satellite; If there is no inter-satellite link between this satellite and other satellites in the visible area, then we can only predict the satellite clock error by given data. The simulation conditions of this paper are as follows: the system error of satellite-ground is 0.5 ns, the random error is 0.5 ns; the system error of inter-satellite is 1 ns, the random error is 0.5 ns. In this case, we can obtain the satellite clock error of PRN02 in an orbital period by method of this paper, and the accuracy is about 1.3 ns.

Abstract: Random sequences generated by different logic functions play an important role in cryptography. The structure and the special properties of the logic function has been one of the most active areas of research. In order to study the random sequence and its related logic functions, many models have been established, and different advanced tools are applied to make complex data visualization. In this paper, sample logic functions are transferred into variant logic expressions to form a set of measurements. Using selected measurements, a 3D visual model is proposed. Selected 3D visual results are shown their intrinsic 3D spatial characteristics of relevant logic functions respectively.

Abstract: The objective of this research is to describe a three-dimensional force measuring system operating in wind tunnel test to investigate the static and dynamic effects of buildings under wind loads. A three-decker structure serves as the elastic element of the three-dimensional force sensor. The solution for overload in the courses of transport, installation and employment is proposed. The set-in hardware circuit is devised to improve the signal-to-noise ratio. A portable box of multiplex data acquisition was designed to achieve synchronous measurement. Multiple sensors were utilized in the measurement of the reacted forces for a rigid model with multiple supporting components in wind tunnel test. The experimental results could provide reference value and significance in the innovation and engineering of industrial measurement.

Abstract: In this paper we present some aspects regarding the measurement of the effects of extended of braking, or the overheating of the braking system of a vehicle driving downhill with continuous or intermittent operation of the braking system. One of the is the extended effects of high temperature of braking brake blocks. To determine their temperature were used thermocouple temperature sensors. To determine temperature friction lining unshielded thermocouple junction was used to reduce the thermal inertia of 1 ÷ 2 [, thus ensuring the greater accuracy of measurement data. To determine the metal part of the brake shoe to temperature using a thermocouple sensor with metal sheathed.

Abstract: Three main fractures exist in coal rock mass, including face cleats, butt cleats, and major fractures. The distribution of cleats and beddings in coal rock mass likes a regular reticular. A geological model was established without considering the major fractures. Young's moduli of fractured coal rock mass were gained through a homogenization method monolayer composite micromechanics analysis method. The relations between volume fraction or Young's moduli of cleat and Young's moduli of coal rock mass were investigated by calculation. Results shown that Youngs moduli of coal rock mass have the same change trends with the increase of volume fraction of cleat in the interval of 0.0018mm of width of cleat. And the width of cleat of 0.5mm is a critical point. Youngs moduli of coal rock mass monotonically increase with the increase of Youngs modulus of cleat in the interval of 0.0010.008GPa. Volume fraction and Young's moduli of cleats have notable effects on Young's moduli of coal rock mass.

Abstract: Photothermal displacement technology is mainly applied in the measurement of the materials optical thermal parameters and the non-destructive testing. In order to study the optical thermal parameters of the anisotropic crystal, heat conduction equation of anisotropic crystal under a given temperature distribution is solved by using an integral transform method. The steady-state temperature field distribution of the crystal is obtained, which is simulated by Matlab and can be applied to the photothermal displacement technology to obtain the surface deformation to provides a strong theoretical basis for studying the optical thermal parameters of the sample.

Abstract: The paper discusses and researches the assessment method of graduation results for basketball elective course in Wuhan Institute of Physical Education preliminarily, by literatures and questionnaires. It is shown from the research results that the comprehensive assessment method based on fuzzy mathematical theory reflects the wide practicality and adaptability in the assessment of elective results in physical academies. The educational assessment of physical colleges is conducted under a special circumstance. Over the last decade, lots of new ideas, new concepts, new models, and new methods of foreign education assessment have appeared, such as: alternative assessment, implementation assessment, and dynamic assessment. Some are more mature with feasibility and application value, some methods are cumbersome, lack of feasibility and universal. The paper pays the full attentions and makes calm analysis for the domestic and international development trends in the assessment, based on the scientific, practical, and innovative way. The discussed fuzzy comprehensive assessment method is a method that applies the fuzzy mathematics to educational assessment filed, which highlights the systematization of assessment index of students. It emphasizes the combination of qualitative assessment and quantitative assessment for a comprehensive, objective, and fair assessment of students' development, to describe the condition and progress of students more clearly and accurately.

Abstract: The competition result of a rhythmic gymnast is dependent on the assessment of referees based on the athletic level of athlete at scene (including the difficulty, choreography, and quality of movements), and final ranking after comparing with the scores of other competitors. The paper proposes several factors which can affect the performances of rhythmic gymnasts including: the subjective factors such as scoring of referees, and also the objective factors such as athletic level of athletes at scene, competition conditions, competitors' conditions, etc.; and the paper also proposes the related countermeasures for above issues.

Abstract: Angle Measure Technique (AMT) algorithm is proposed to analyze the quality of batch drilling process in this paper. The groups spindle power (SP) signals of batch drilling were preprocessed by the normalization method, and then the AMT was used to extract the scale features of monitor signals from local to global. By the method of Principal Component Analysis (PCA), the dimensionality of these scale features was reduced to obtain a distribution of the step quality of batch drilling. The results indicate that this method can be used for observation of high precision cutting step quality.
