Synthesizing graphitic spheres using asphaltene-based materials by vacuum heat treatment

Cailiao rechuli xuebao (2007)

Xiaomin Wang Guo Jun-jie

This paper aimed at the high added value use of a deoiled asphaltene.Monodispersed highly graphitized graphitic spheres (GSs)with high thermal stability were synthesized by vacuum thermal processing followed chemical vapor deposition (CVD).The carbon microbeds and the synthesized GSs were compared by means of SEM,HRTEM,XRD and TGA.Vacuum thermal processed GSs are of high degree of graphitization and good thermal stability.The disordered structure of carbon microbeds were thermodynamically propelled to transit to the graphitic structure,forming the GSs.

Feasibility analysis study of discrete modulation continuous variable quantum key distribution for spatial channels

Acta Physica Sinica (2025)

Xin Sun Guo Jun-jie Yujie Chen Cheng Jin L. Ao

Continuous Variable Quantum Key Distribution (CV-QKD) has emerged as a promising candidate for quantum-secure communication due to its experimentally demonstrated high key rates in fiber-optic channels. However, the feasibility of discrete modulation CV-QKD in satellite-to-ground downlinks remains an open question due to practical challenges such as high transmission loss, limited communication windows, and atmospheric turbulence. In this paper, a comprehensive framework is proposed to evaluate the feasibility of discrete modulation CV-QKD by integrating orbital dynamics and atmospheric channel models, with a full analysis of the impact of the parameter space on free-space discrete modulation CV-QKD. To achieve this, a free-space CV-QKD simulation platform is employed, which calculates the elevation angle and transmission distance based on precise orbital models, thereby providing a more practical assessment of the key rate for discrete modulation CV-QKD. Simulation results verify the feasibility and practicality of discrete modulation CV-QKD in satellite-based quantum communication systems. Furthermore, critical factors affecting the key rate performance are identified, and parameter optimization strategies are proposed, offering theoretical support for the future implementation of satellite-to-ground discrete modulation CV-QKD.

The innovation and path dependence of scientific research management in our country's universities & colleges

Kexuexue yanjiu (2007)

Guo Jun-jie

The scientific and technical transformation of the universities colleges in our countries is an important impetus to impelling the management of scientific-technical innovation and the development of market economy.But the bad influences of system,mechanism and idea upon the scientific and technical transformation result in there are many l achievements of technological research could not transfer into productive forces.In this article,according to the correlative theory of path dependence,the author analyze the status in quo and obstacles during the management of science research achievements in our country's universities colleges,further more,some innovative approaches to deal with scientific research management in the universities colleges of our country.

Estimating Dynamic Stiffness of Coordinate Measuring Machine for Compensation of Acceleration Error

Xi'an Jiaotong Daxue xuebao (2009)

Guo Jun-jie

A method to estimate the stiffness and damping of the aerostatics slideways of coordinate measuring machine(CMM) for the compensation of acceleration errors is proposed.The vibration equations of CMM are established from the framework model of CMM and transformed into the form of the frequency response functions(FRFs) of first order systems,where the identified parameters are contained.The FRFs are tested and then the stiffness and damping parameters can be identified with Bode diagram rather than Levy method.Modal analysis is performed on CMM system after the identification of stiffness and damping parameters.The acceleration errors are forecasted with modal superposition method.Experiments indicate that the cross-correlation coefficient between the measured errors and the forecasted errors at CMM probe tip is over 0.7,which verifies the effectiveness and reliability of the proposed method.

Recoverable Resin Bolt Anchoring Section Anchoring Characteristic Study

Guo Jun-jie

Distributing form and correspond data of shear stress τ and normal stress σ on the interface of wall rock and resin anchoring section is educed by ANSYS simulation,and shows that anchoring action occurs mostly at deep anchoring section,where under extrusion swell state.The conclusion that the interface normal stress enhances shear strength of anchoring section is drawn from Coulomb Criterion.
