Information can be collected search engine on the Web, but the current search engines can only interpret the characteristic structure of web page data from the perspective of syntax, is lack of semantic understanding, and thus cannot find the desired information quickly and accurately. In order to solve these problems, this paper proposes an information mining model of intelligent Collaboration based on agent technology. By analyzing the information mining process, more to understand the mechanism of Collaboration mining, thus can help users find faster and better desired information.

Regular rare earth permanent magnet measurement systems are only able to measure standard samples with a fixed size. But NdFeB materials are usually processed into various kinds of shapes. Bonding magnets are even often formed together with the shaft or other parts. So there will be a distinct error in conventional measurement. The magnetic field intensity distribution between two poles of the system was analyzed. Because of the existence of air gap between the magnet and the poles of the measurement system, the measurement magnetic circuit is open in this experiment. By changing the height of the magnet and air gap, the measurement error of the intrinsic coercivity Hcj of NdFeB magnets is researched under this condition.

A femtosecond laser machine consisting of femtosecond fiber laser, trepanning head, linear motor stages system and Siemens 840D system has been integrated for industry application. The femtosecond laser source is all fiber system which contains a fiber mode-lock laser at 1053 nm with a repetition rate of 3.9 MHz, a double-cladding gain fiber amplifiers and a PCF amplifier. An acoustical modulator has employed to tune repetition rate from 3.9 MHz to 100 KHz. An in-line fiber chirped grating is used to stretch the pulse duration to 700 ps. After the PCF amplifier pulse is compressed to sub-ps with 50% efficiency based two grating compressor. The system outputs an average power of 15 W at 100 KHz and 800 fs. Using four wedges trepanning head, cylinder hole is drilled in 1mm thickness SiC ceramics in 30 s.

Context-aware applications can sense and explore the context of production processes to provide proper and useful services to managers in workshop. The monitoring levels are partitioned and designed in this article. And the multi-level ontology model of materials is found which is expressed in the Web Ontology Language (i.e. OWL) as a ontology collection of describing places ages and events and associated properties among them. Within an intelligent monitoring system, dynamic adjusting algorithm of linking local coordination with global coordination for lacking parts is brought forward and dynamic coordination structure is put up based on event-driven architecture. Context-aware reactive behaviors can be expressed by using rules written in OWL Language, especially developed for context-aware applications.

To optimize scheduling pertaining to two production units and many tasks in flexible production, a dynamic scheduling model was proposed considering capacity balance. Each production unit was modeled as a kind of container whose capacity symbolized the container capacity. The capacity was divided as planned and spared parts. Joining spared capacities in two units, the state-to-art dynamic scheduling rules were created according to hydro-mechanical theory. A practical heuristic algorithm was developed for this model. The model was tested as feasible and effective in a case study conducted at an actual business.

Through the facilities imitating experiment of film hole irrigation with nitric acid potassium solution under different film hole diameter, the content of soil water and nitric nitrogen was determined and analyzed in the different time after irrigation. The result shows: the content of soil water and nitric nitrogen under different film hole diameter reduced with time and achieved the maximum at the center while it is reverse away from film hole; soil water content decreased with the increase of film hole diameter at the same position while the nitric nitrogen content was opposite. The influence of the increase of film hole diameter on soil water and nitric nitrogen distribution is harm for plant to absorb water and nitric nitrogen, so it will be better to reduce the film hole diameter in the agriculture production. The result provided the proof for the sustainable development of facilities agriculture and evaluating the effect of nitrogen on environment.

The effect of initial water content on water transport characteristics in injection irrigation is analyzed through an indoor experiment of injection irrigation in different initial water contents. The research shows the following results. The relationship between the cumulative infiltration and time accords with power function. The higher the initial water content is, the bigger the cumulative infiltration is in the same time. The wetting front is a semi-circle with its center below the water outlet, the transport velocity of which slows down with the passing of time. The transport velocity of vertical section crossing the middle of the two outlets approaches that of vertical section at the middle point of the central line of the two outlets. The higher the initial water content is, the shorter the time of the transport velocity of the two sections similar to each other is. The water wetted range is comparatively wider, and the water content is comparatively higher below the outlet, and it is reverse above the outlet. The higher the initial water content is, the wider the wetted range is and the higher the water content of the soil being the same distance from the outlet is. The above research provides a basis for supplementing the theories and technologies of injection irrigation.

The method of measuring saturated soil hydraulic conductivity by using permeating bucket is easy and simple and the instrument is cheap. The water volume must be measuring for many times, meanwhile the water must be added on the top of permeating bucket to sustain the water layer thickness. Based on the principles of supplying water in the fixed water head by Marriott bottle, the method mentioned above is improved, which can reduce the experiment work and improve the experiment accuracy.

Through the experiment of different Irrigation Amounts with urea applied, the paper studied the influence of Irrigation Amounts on soil nitric nitrogen dynamical changes under film hole irrigation and the nitric nitrogen content of the growing period was determined. The result showed: different irrigation amount in the profiles being 3cm and 8cm away from the film hole center, it appeared nitric nitrogen accumulation peaks, increased the irrigation amount promoted the transformation of urea, increased the transformed nitric nitrogen content and distribution of nitric nitrate and the risk of nitric nitrate leaching. In the profiles being 3cm away from the film hole center, the nitric nitrogen accumulation peak significantly reduced at harvest stage, but it reduced in the profiles being 8cm away from the film hole center at milky stage. The milky stage was the maximum period when the corn uptook nitrogen at different irrigation amount. Increased irrigation amount lower the accumulation content of nitric nitrogen near the film hole center after harvest, and higher the accumulation content of nitric nitrogen far away from the film hole center. Above researches could provide the basis for rational fertilization of farmland and nitrate environmental impacts on assessment.

The aim of this paper is to study the adsorption characteristics of nitric oxide (NO) and sulfur dioxide (SO2) on raw coal activated carbon over temperature ranged 298～343K using a static volumetric adsorption apparatus. The adsorption equilibrium data for NO and SO2were fitted to Freundlich, Dubinin-Radushkevich (D-R) and Sips adsorption isotherm model. Isosteric heat of adsorption was determined by the Clausius-Clapeyron equation. It was found that Sips adsorption isotherm model is more suitable for description of NO adsorption process at 298K, 313K and 328K and SO2adsorption process at 313K, 328K and 343K, however, D-R adsorption isotherm model is more suitable for description of the NO adsorption process at 343K and SO2adsorption process at 298K. The isosteric heat of adsorption values of SO2increase slightly as the adsorbed amounts increasing from 0.8 to 1.6mg/g, but the isosteric heat of adsorption values of NO show a converse trend. Meanwhile, NO and SO2adsorbed on coal activated carbon at the four temperatures may be a dominant of physical adsorption.

Mn-Co-Ox catalyst was prepared by the co-precipitation method. The most active catalysts were obtained with a molar Co/(Mn+Co) ratio of 0.1. The results showed that over this catalyst, NO oxidation conversion reached 56% at 150°C and 59% at 175°C with a high space velocity of 35000h-1. Their surface properties were evaluated by means of scanning electron microscopy (SEM) and X-ray diffractometer (XRD). The process of Non-thermal plasma-assisted catalytic oxidation of NO under low-temperature was studied. And the NO conversion could reach 71% with the Non-thermal plasma-assisting at 125°C when the input voltage was 30V. The increasing activities at low temperature (50-150°C) were more apparently higher than high temperature by plasma. And the low-temperature catalytic activity of the catalyst was increased with the increase of the input voltage.
