To recycle the waste heat in the exhaust gas of marine diesel engine, a new drying room heated by marine diesel engine exhaust gas is introduced. The drying room's structure, working principle and the main design parameters calculating methods is designed. Comparing to the traditional heating methods, this kind of drying room make full use of the heat energy and will acquire huge economic benefits. © (2013) Trans Tech Publications, Switzerland.

The UV spectrograph Spectroscopy for the Investigation of Characteristics of the atmosphere of Mars (SPICAM) on board Mars Express made the first observation of auroral-type emission in the cusp region of strong crustal magnetic field on Mars and found that the arc of Martian aurora is very narrow in width, which obviously differs from that of other planets. Based on the observation, we put forward a model of crustal magnetic field on Martian aurora zone through the morphology of Martian aurora. In the model, equivalent currents are proposed, the topology and magnitude of magnetic field generated by these equivalent currents is consistent with that of crustal magnetic field on Martian aurora zone. The morphology of Martian aurora generated through the model matches well with the observations by the Mars Express orbiter. © (2013) Trans Tech Publications, Switzerland.

The transition phase and electronic properties of LiBH4 were investigated by ab initio plane-wave pseudopotential density functional theory method. According to the theoretical calculation, the phase sequence Pnma → P21/c → Cc is obtained. The phase transitions Pnma → P21/c and P21/c → Cc are at the pressure of 1.64 GPa and 2.83 GPa, respectively, by total energy-volume data. As the pressure increases, the value of the band gap energy is reduced from 7.1 (Pnma) to 6.1 eV (Cc). Moreover, the electronic properties of the high pressure phases are discussed. The electronic properties are linked to the band gap energy, total (partly) density of states and atoms (bond) populations. © (2014) Trans Tech Publications, Switzerland.

The complex environment maritime police ship at sea duty law enforcement faced manipulation skills of the crew put forward higher requirements. Evaluation of manual evaluation method is one of law enforcement vessels manipulation skills commonly used methods, the results have certain subjectivity and arbitrariness. This paper attempts to establish a fuzzy comprehensive evaluation model evaluation index. The use of computer-aided technology preparation software, through a narrow channel simulation case study Captain comprehensive evaluation skills to manipulate the situation. Compared with the artificial evaluation, the error is small, the results more objective. © 2013 IEEE.

Eu-doped ZnO (ZnO:Eu) hollow nanofibers were fabricated by sputtering using electrospun PVP nanofibers as templates. The morphologies, crystal configuration, bonding structures and optical properties of the ZnO:Eu hollow nanofibers were characterized, respectively. Raman results indicate that there are many oxygen vacancies and/or interstitial zinc in ZnO:Eu hollow nanofibers. Effect of Eu-doping on vibrating modes of ZnO is attributed to the change of defects and impurities due to incorporation of europium. The high intensity ultraviolet emission and red luminescence of the ZnO:Eu hollow nanofibers are observed due to the random lasing of near-band-gap emission of ZnO and an f-f transition of the Eu3+ ions, respectively. © (2014) Trans Tech Publications, Switzerland.
