Abstract: The fast pyrolysis of corn straw in the fluidized bed reactor to produce bio-oil, the preliminary qualitative research on the composition of the bio-oil was analyzed by GC-MS to provide the basis for their purification, refining and long-term stability studies. The result shows that: the bio-oil producted by corn straw pyrolysis contains 66 components, mainly containing phenol, furan, acetic acid, propanoic acid, ethanone, vanillin, aldehyde, bio-oil water content is 33% and pH is 3.1, which has a great significance to improve the quality of bio-oil.

Abstract: In this paper, based on the analysis of ordinary visual modeling method, with the purpose of instantly and conveniently providing a more effective modeling method, a visual modeling method based on .NET is proposed. The visual modeling method based on .NET is easier to implement, because of the. NET design environment support. Besides, its interactivity and strong operability make software develop more conveniently.

Abstract: This paper presents a comprehensive virtual simulation model for CNC systems. The Virtual CNC (VRCNC) has a modular architecture and the special function. It can show movement process and the result, it can also show the effect of different movement mode, the displacement, velocity and acceleration of the process, the rationality of interpolation method and the motion control method. Additional CNC modules can easily be prototyped and integrated to the VRCNC by the user. Various application examples are presented which include building of physical dynamic control model, the prediction of the displacement, velocity and acceleration of the process, and the process of secant instead of curve. It can show closed loop drive dynamics. Detailed experimental verification is presented for each algorithm.

Abstract: The sphere-like diamond microcrystalline-aggregates were fabricated by microwave plasma chemical vapor deposition (MPCVD) method. The ceramic with a Ti metal layer was used as substrates. The fabricated diamond microcrystalline aggregates were evaluated by Raman scattering spectroscopy, x-ray diffraction spectrum (XRD), scanning electron microscopy (SEM). The field emission properties were tested by using a diode structure in a vacuum. A phosphor-coated indium tin oxide (ITO) anode was used for observing and characterizing the field emission. It was found that the sphere-like diamond microcrystalline-aggregates films exhibited good electron emission properties. The turn-on field was only 0.55V/μm, and emission current density as high as 11mA/cm2 was obtained under an applied field of 2.18V/μm for the first operation. After several cycling operations, the field emission tended to stable characteristics of current versus voltage. The stability evolvement and mechanism are investigated relating to microstructure of the sphere-like diamond microcrystalline-aggregates films.

Abstract: Common Image Generation Interface is the interface between two real-time communication subsystems. In order to exchange data between control end and rendering end of the scene simulation system, a packaging component based on common image generation interface is proposed in this paper, which is applied to visual simulation of helicopters and fighter. The simulation results show that this method can meet the real-time requirement of visual control system and is valuable in visual simulation of the weapon equipment operational field.

Abstract: This paper considers the factor of a mechanism based on customer, with the purpose of getting to know the different characteristics that must be taken into account during the development of software as a procedure. This also involves the attending of all kinds of relevant person of the Information system model together with the users’ message exchanging experience. This paper offers a mechanism of the related role in the design of a software component as a procedure, with the target of confirming their attending outside and within the organization. The purpose is to create a component centered on the user, involving clients and experts to work collaboratively; and get usable software as information system.

Abstract: Efficiency is the key of project management, and conversion of project knowledge to technology must be realized by establishing an effective management system. Component project management system is based on the enterprise level rather than project manager level. Although the project has unique characteristics, the member companies use the same or similar components in different projects. It converts internal and external enterprise knowledge into technology, and implementation steps are carried out based on the component of project management system in enterprise organization to ensure project technical transformation of the knowledge flow and call mechanism of project management component, in order to realize the application of component-based project management system in enterprise organization.

Abstract: This paper focuses on the faults of military software system based on component. The faults are caused by external reasons during the using process of the software system. The method for faults diagnosis is based on the theory of expert system. The study finds that, there exist redundant questions during the reasoning process due to the uncertain factors and technical limitations of diagnosis system users. In order to improve the efficiency and reliability of military software fault diagnosis, a hybrid reasoning strategy was proposed. The strategy is based on the serial combination of uncertainty reasoning and interactive reasoning. Experimental result shows that the method based on the hybrid strategy for military software faults diagnosis is more accurate and flexible compared with the traditional reasoning method. The method also has improved the assurance work of military software system.
