A back-illuminated vertical-structure ZnO ultraviolet (UV) detector was fabricated using an indium-tin oxide (ITO) electrode. Ordered ITO and ZnO films were grown on a quartz substrate by radiofrequency sputtering. At 5 V bias, the dark current was 640 μA and the photocurrent was 16.8 mA under UV illumination (365 nm, 10 μW), indicating a high responsivity of 1616 A/W. The response time measurements showed a rise time of 71.2 ns and a decay time of 377 μs. The ZnO detector performed well and can be used in a focal-plane array for UV image detection.

Adopted the distribution feedback type (DFB) laser to measure the coal mine gas methane, according to the methane located 1.6 μm nearby 2 ν 3 with a R9 direct absorption spectrum, attraction wire intensity of each line was calculated through the multi-line Voigt fitting. The experimental result indicates that in the obtained four attraction recover of wire, the maximum deviation is 2.7%, and the minimum deviation is 0.02%, other results are all in experimental error scope. This research method may apply in the spectrum survey methane gas density, it has characteristics including high precision, strong selectivity, fast response and so on. [ABSTRACT FROM AUTHOR]

A high-performance metal-semiconductor-metal (MSM) ultraviolet photodetector was fabricated based on a ZnO film with Al interdigitated (IDT) electrodes. A c-axis-oriented ZnO film was grown on a SiO2/Si (100) substrate at room temperature by a reactive radiofrequency (RF) sputtering technique and then annealed at 900°C in pure O2 ambient for 1 h. The fabricated ZnO ultraviolet (UV) detector demonstrated a high responsivity of 2069 A/W when biased at 5 V, which could be attributed to the influence of the annealing process in pure O2 ambient. The response time measurement showed a rise time (10-90%) of 45.1 ns and a decay time (1 - 1/e) of 541 µs. [ABSTRACT FROM AUTHOR]

The P spectra of pion from resonance decay are studied. It is found that the reduction of effective mass increases the emission of low P pions. The approach to explain the enhancement of low- P pion observed by the NA35 Collaboration in 200 GeV S+S collisions with the contribution from the resonance decays can be improved by the mass reduction.

The two phase model for the quark-gluon deconfinement phase transition is modified based on the tempreature and density related properties of the hadron. The revised approach is consistent with the single body description. Its consequences on the pressure and energy density of the hadron gas is investigated, and the critical value of temperature and chemical potential of the phase transition from the hadron gas to a non-interacting quark matter are calculated. Our results agree with the recent lattice gauge calculations. [ABSTRACT FROM AUTHOR]

Within the framework of ellipsoidal bag model, the $$Q\bar Qg$$ state at finite temperature is investigated, and the dependence of the energy of the system on the interquark separation is obtained. We calculate the spectrums of $$B\bar Bg$$ and $$C\bar Cg$$ states at different temperature for TM and TE mode respectively. [ABSTRACT FROM AUTHOR]

The Q $$\overline Q $$ system at finite temperature is investigated based on the ellipsoidal bag model. It is found that the binding energy decreases with increasing temperature. [ABSTRACT FROM AUTHOR]

The experiment given by BEBC TST Neutrino Collaboration was reanalysed. From the ν and $$\overline \nu $$ hydrogen data the strange-quark distribution in a free proton is extracted. The difference between s and $$\overline s $$ distributions is seen, but cannot be confirmed yet. More precious ν and $$\overline \nu $$ hydrogen data are necessary. [ABSTRACT FROM AUTHOR]

Due to the violation of the Gottfried sum rule, the quark model is slightly modified as $$\bar u = 2\bar d$$ instead of $$\bar u = \bar d$$ in proton. We reanalyse the recent experiments and find that this picture is self-consistent. In this picture about 54% of the proton spin is carried by the spin of quarks. [ABSTRACT FROM AUTHOR]

The cutlassfish (Trichiurus haumela) is an important commercial fish species. In the present study, we report 12 polymorphic microsatellite DNA markers for cutlassfish. The number of alleles per locus ranged from 2 to 9 in a sample of 26 individuals. Observed and expected heterozygosities per locus varied from 0.2727 to 0.9583 and from 0.4059 to 0.7926, respectively. Two loci (Trha25 and Trha27) showed significant departure from Hardy- Weinberg equilibrium after sequential Bonferroni correction (P<0.0042). No significant linkage disequilibrium between pairs of loci was found. These microsatellite markers provide powerful tools for investigating genetic population structure, population history and conservation management of cutlassfish. [ABSTRACT FROM AUTHOR]

This paper reviews twenty-eight Chinese medicine books with complete prescriptions prior to the Qing Dynasty, and analyzes the characteristics of acupoint selection and needling manipulations from the perspective of apoplectic symptoms. It is concluded that, in ancient times, apoplexy is often treated on the basis of its symptoms and a great number of acupoints are employed; hemiplegia is mainly treated by the acupoints of the Large Intestine Meridian and Gallbladder Meridian, with two key acupoints; coma is mainly treated by first-aid acupoints and qi-supplementing acupoints, with seven key acupoints; wry mouth and convulsion are mainly treated by the local acupoints; as for needling manipulations, moxibustion with moxa cones is principally used, while needling is less used.

The quark condensate in nuclear matter is studied. We relate it to the nuclear sigma commutator, and then treat it as sigma commutator for quasi- particles in a self-consistent way. We find that the deviation from the linear expression is large at high density. [ABSTRACT FROM AUTHOR]
