As one of the important parameters for the production process of industry, agriculture and military, temperature can affect the production efficiency, energy efficiency and people’s living standards. The temperature measurement has been widely noted and studied. Firstly, the software can receive the temperature of measuring point, and store the value in the database. Secondly, when the temperature exceeds the specified range, the software will give an alarm. The software can view the historical temperature data and draw the curve of temperature. Finally, the software can query and modify the information of the measuring point, such as number, name, normal temperature range of equipment, etc. Based on the existing research results, this paper describes the design and implement of wireless temperature measurement software for electrical equipment.

Effects of atomic oxygen (AO) irradiation on the structural and tribological behaviors of MoS2 filled polyimide (PI) composites were studied by using ball-on-disc tribometer, infrared spectra, X-ray photoelectron spectroscopy and scanning electron microscopy. It was found that the irradiation of AO induced the destruction of polymer molecular structures and formation of volatile products which induced the change of the structure, morphology and tribological properties of samples. The addition of MoS2 filler significantly increased the AO resistance of PI composites due to the formation of MoO3-rich skin layers during AO process. The addition of MoS2 improved the tribological properties of PI before and after AO irradiation.

Based on spherical head models, this paper, by employing the finite element method (FEM), analyzes the potential distribution of the brain scalp surface and attempts to work out the electroencephalography (EEG) forward problem, in hope of finding out the impact the dipole parameters has on it. According to the electromagnetism theory, this paper discusses the general resolution of EEG, it requires electric potentials of the globe's surface, and graphically displays results of computation through finite element post-processing, which tests their effectiveness. Furthermore, it analyzes the influences of dipole parameters on the potential distribution of scalp surface, such as position, direction and strength, which attempts to provide an effective method to solve EEG forward problem, based on diversified head model, and also proposes a prior information to the solution to EEG inverse problem.

The reduction of sauter mean diameter (SMD) of droplets means the percent of the evaporated fuel, which is important to the formation of the combustible mixture in a port-injection gasoline engine during cold-start. Three-dimensional numerical simulation of SMD of the droplets in the inlet port of a gasoline engine was employed using the CFD software. This paper presented the effect of multi-parameters on SMD of the droplets including initial droplet velocity, intake temperature, fuel temperature, injection timing and engine speed. The simulation results show that the most influential parameters on SMD of the droplets are intake temperature and fuel temperature. The fuel evaporation rates increase approximately linearly with the intake air temperature and fuel temperature increasing. The initial droplet velocity and injection timing have a little effect on the fuel evaporation. As engine speed increases, SMD of the droplets firstly decreases and then increases. After intake-valve-open (IVO), back flow of gas in cylinders results in steep reduction of droplet diameter.

The diffusion combustion of the air heater was numerically simulated at different excess air coefficient using Fluent software. The distributions of the temperature, gas flow velocity, and turbulence intensity were present. And the heat flux was calculated. The result showed that the excess air coefficient had a little effect on the maximum combustion temperature distribution. As the excess air coefficient increased, the axial temperature at first increased and then decreased, and in contrast both the total heat flux and radiation heat flux decreased. The radial temperature, velocity and turbulence intensity increased firstly and then decreased at the same operation condition. The measured exhaust temperature increased with time. At 90 second, it was about 250 ℃, which showed good agreement with simulation result. This provides theory basis for the reform of the heater.

The DNA nuclease-like activity of a water soluble manganese corrole 5, 10, 15-tris(N-methyl-4-pyridyl)- corrolatomanganese(III) (MnIIITMPyC) has been investigated. MnIIITMPyC may bind strongly to DNA via outside groove binding mode as indicated by absorption spectra, viscosity measurements and CD spectra. MnIIITMPyC exhibited excellent catalytic activity in the DNA oxidative cleavage in the presence of hydroperoxide.

The reductive demetalation of manganese corroles was investigated in CH2Cl2/HCl (aqueous) solvent by using SnCl2 as reducing agent. It was found that the demetalation yields depend on the substituents of corrole macrocycle significantly. Electron-rich manganese corrole undergoes reductive demetalation more easily than electron-deficient ones. The isolated reductive demetalation yield of manganese 5,10,15-tris(phenyl)corrole in present system is moderate (46%). As for electron-deficient Mn(III) 5,10,15-tris(pentafluorophenyl)corrole, the acid-induced demetalation in HOAc–H2SO4 (V/V=3:1) is preferable with an isolated yield of 67%.

Abstract Three new CoIII complexes: [Co(bpy)2(pdtb)]3+(1), [Co(bpy)2(pdta)]3+(2) and [Co(bpy)2(pdtp)]3+(3) have been synthesized and characterized. The DNA binding behavior of the CoIII complexes has been investigated by spectroscopic methods and viscosity measurements. The results indicate that the size and shape of the intercalated ligand have a marked effect on the binding affinity of complexes involving CT-DNA. Complexes (2) and (3) have been found to promote cleavage of plasmid pBR 322 DNA from the supercoiled form I to the open circular form II upon irradiation. Photocleavage mechanisms are proposed.

Two novel RuIIcomplexes [Ru(dppt)(bpy)Cl]ClO4(1)and [Ru(pta)(bpy)Cl]ClO4(2)[dppt, pta and bpy = 3-(1,10-phenanthrolin-2-yl)-5,6-diphenyl-as-triazine, 3-(1,10-phenanthrolin-2-yl)-as-triazino[5,6-f]acenaphthylene and 2,2′-bipyridine, respectively] were synthesized and characterized by elemental analysis and electrospray mass spectrometry, 1H-n.m.r., and u.v.–vis spectroscopy. The redox properties of the complexes were examined using cyclic voltammetry. Due to the strong π-accepting character of asymmetric ligands, the MLCT bands of (1)and (2)are shifted significantly to lower energies by comparison with [Ru(tpy)(bpy)Cl]+.

Two novel tridentate ruthenium(II) complexes containing an asymmetric heteroaromatic and a polyamine ligand, [Ru(dipn)(dptp)](ClO4)2 (1·2 $\rm{ ClO_4^ -}$) and [Ru(dipn)(pat)](ClO4)2 (2·2 $\rm{ ClO_4^ -}$) (dipn=N-(3-aminopropyl)propane-1,3-diamine; dptp=2-(5,6-diphenyl-1,2,4-triazin-3-yl)-1,10-phenanthroline; and pat=9-(1,10-phenanthrolin-2-yl)acenaphtho[1,2-e][1,2,4]triazine) were synthesized and characterized by elemental analysis, ESI-MS, ¹H-NMR, UV/VIS, and cyclic voltammetry. The DNA-binding behavior of both complexes was studied by absorption titration, thermal denaturation, and viscosity measurements. Results indicate that complex 2 binds to calf-thymus DNA in an intercalative mode but complex 1 binds to DNA in partial intercalation, and the DNA-binding affinity of complex 2 is much greater than that of complex 1. Theoretical studies for these complexes were also carried out with the density-functional-theory (DFT) method. The trend in the DNA-binding affinity and some electrochemical and spectral properties of the complexes can be further explained applying the DFT computational results.
