We report on the time reference system of Compass global satellite navigation system and its interoperation with other GNSS’s. China has sent three satellites into geostationary orbit since 2000, and Compass Navigation Test System has been established. Compass time reference, named as BDT, is based on Atomic time, BDT is derived from the atomic clock ensemble in Compass ground control centre, and be traced to the international time, UTC. Interoperability is one of the most important aspect in the design of Compass timing system, a solution of time differences determination among BDT and other GNSS time scales are introduced in this paper.

AbstractIn the current study, for rapid detection of azocylotin residues in agricultural products, the Co3O4/PAn nanoparticles modified electrochemical immunosensor was generated successfully. Azocylotin-BSA artificial antigen coupling to the surface of the working electrode coated with the Co3O4/PAn nanoparticles thin-layer, the competitive inhibition reaction is launched between the azocylotin in the samples and the azocylotin coupled on the electrode with the azocylotin monoclonal antibodies in the test system. The antigen-antibody reaction signal conductive amplified by the coupled silver nanoparticles, and then the electrolytic current in the reaction system was detected. After establishing basic detection system, a series of optimization including the concentration of immobilized membrane optimization, electrode surface coated material composition optimization, selection of buffer, coupling antigen concentration optimization and anti-antibody label optimization will be done. Subsequently, the concentrations of azocylotin in samples of standards, orange and apple were tested, and the results indicated that this immune sensor has good sensitivity and high accuracy. The research could provide the reference for the research, development and application of sensors to realize rapid detection of pesticide residues in agricultural products.

In order to study the physical phenomena and mechanical properties of cutters when cutting rock, a test apparatus for cutting performance of cutters of large excavation equipment is established. The test apparatus is composed of a vertical loading system, a rotary loading system, a control system and a test system. Tests of different cut penetrations and spacings were carried out using the test apparatus. Meanwhile, the real-time images of the cutting process and forces acting on the cutters were obtained. The result shows that the test apparatus has good practicality and reliability, and it provides a laboratory test method to study the cutter-rock coupling mechanism and cutting performance of cutters.

MEMS sensor for solution conductivity measurement has been applied widely which has many advantages such as cheap, accurate, batch fabricate, and good consistent etc. Existent MEMS conductivity sensors usually have planar structure with four short parallel electrodes so that the two voltage electrodes are tend to be polluted and consequently lead to mistakes for the conductivity test system. A new pattern of conductivity chip with an annular voltage electrode to enhance the ability of anti-pollution based on MEMS technology is going to be introduced in this article; the ANSYS simulation is applied to help demonstrate the reasons why the new pattern of conductivity chip has good ability of anti-pollution and the experiment results are also presented to show the performance of the conductivity sensor.
