The waveguide invariant,denoted asβ,can be used to describe the slope of the intensity of a broadband acoustic *** deep water,the interference patterns of the areas with dominant waterborne modes and only with bottom bounce modes are greatly *** phenomenon is illustrated by simulation and explained by the distribution ofβ.The theory shows that in the convergence zone,βapproaches infinity,which leads to the larger slope of sound intensity;on the contrary,in the shadow zone,βis close to 1,leading to smaller slopes.

Solid lipid nanoparticles loaded with bovine serum albumin（BSA） were prepared by a double emulsion method. As the mass fraction of the model drug BSA increased from 0 to 15%, the particle size gradually increased. The physical stability of the nanoparticles was investigated by zeta potential measurement and they were shown to be quite stable. Fluorescence spectroscopy confirmed that the loaded position of BSA was on the interface between the inner aqueous phase and the solid lipid phase. Both Fourier-transform infrared spectroscopy and circular dichroism spectra indicate that BSA in the nanoparticles was not destroyed, but the secondary structure was disrupted slightly.

In order to gain a better understanding of rice flower development, a rice flower mutant supernumerary Iodicules （snl）, which was identified from ethyl methane sulfonate （EMS）-treated Jinhui10 （Oryza sativa L. ssp. indica） was used in the present study. In the snl mutant, the palea obtained lemma identity, additional glume-like organs formed, Iodicules increased and elongated, stamens decreased, and a few aberrant carpels formed. These phenotypes suggest that SNL is involved in the entire rice flower development. SNL was mapped between two simple sequence repeat markers RM3512 and RM1342 on chromosome 2, an approximate 800 kb region, and it co-segregated with SSR215. We conclude that SNL is a novel gene involved in flower development in rice. The present study will be useful for further cloning of the SNL gene, which will contribute to the elucidation of rice flower development.

X-ray photoelectron spectroscopy has been used to measure the valence band offset （VBO） at the GaN/Ge heterostructure interface. The VBO is directly determined to be 1.13 ±0.19 eV, according to the relationship between the conduction band offset AEc and the valence band offset △Ev：△Ec =EgGaN -EgGe - △Ev, and taking the room-temperature band-gaps as 3.4 and 0.67eV for GaN and Ge, respectively. The conduction band offset is deduced to be 1.6±0.19 eV, which indicates a type-I band alignment for GaN/Ge. Accurate determination of the valence and conduction band offsets is important for the use of GaN/Ge based devices.

From June 1984 to May 1985, monthly and seasonal panel tests of fouling organisms were carried out on rafts at Tuoji Island. Seventy - three species were obtained. The occurring frequencies of the following species are all at least 30%: Ectocarpus confervoides, Polysiphonia urceolata, Tubularia mesembryanthmum, Cfytia edwardsi, Tubulipora pulchra, Celleporella hyalina, Mytilus edulis, Hiatella arctica, Caprella acanthogaster, Corophium crassicome, Jassa *** and Podocerus cf . inconspicuus. Large or calcareous species are not dominant ones. The wet weight is comparatively light, the yearly wet weight being 9.12 kg m-2. Attaching seasons of major species are from June to October and no bio - attachment occurs between January and April. Fouling organisms at Tuoji Island differ rather greatly from those in the harbours along the continental coast, showing the charcteristics of fouling organisms in the northern island harbours of China.
