The toxicity of soil irrigated with treated domestic wastewater （site A） and untreated gray wastewater （site B） were investigated. Soil extracts were prepared using distilled water, acid solvent （0.1 mol·L-1 HCl）, and organic solvent （acetone：petroleum ether：cyclohexane= 1：1：1） to understand the type of pollutants responsible for the ecotoxicity associated with wastewater irrigation. The soil toxicity was assessed using a luminescence inhibition assay with Vibrio fischeri for acute toxicity, a micronucleus assay with Vicia faba root tips and a single cell gel electrophoresis assay of mice lymphocytes for genotoxicity. The physicochemical properties and the heavy metal （HM） contents of the irrigated soil were also analyzed. The results indicated that the wastewater irrigation at site A had no effects on the soil properties. With the exception of Pb, Zn, Fe, and Mn, the accumulation of HMs （Cu, Ni, and Cr） occurred. However, the irrigation at site A did not result in obvious acute toxicity or genotoxicity in the soil. The soil properties changed greatly, and HMs （Cu, Ni, and Cr） accumulated in site B. There were significant increases in the acute toxic and genotoxic effects in the soils from site B. The ecotoxicity in site B came primarily from organic-extractable pollutants.

The surface nanocrystallization of amorphous Fe73.5 Cu1Nb3Si13.5B9 radiated by CO2 laser was studied by means of M（oe）ssbauer spectroscopy, transmission electro iroscope and X-ray diffraction. The result shows that under certain technical conditions, nanocrystalline is fiound on the surface of amorphous Fe73.5 Cu1Nb3Si13.5B9 radiated by laser; the crystallization phase is α-Fe（Si） crystalline, and its size is about 10-20 nm; the nanocrystalline is uniformly distributed on amorphous base to keep the amorphous and crystallized phase in balance; the a mount of crystallization reaches 23% when the laser power is 300 W, the diameter of light spot is 20 mm, and the radiation speed is 20 mm/s. The phase balance can be controlled by adjusting the laser technology parameter. Laser radiation on the amorphous Fe73.5 Cu1Nb3Si13.5B9 alloy is an important technique for surface nanocrystallization of the amorphous alloys.

立春之"霞(kasumi)"这一和歌意象的成立,包含着中日两国文化的冲突与融合。从文字表记上看,日本歌人以"霞"表意"kasumi"的做法受到了中国诗歌中"烟霞"一词流行的影响。从季节认识上来看,"kasumi"直接来源于日本本土自然历中"haru"的季节感,带有鲜明的地域性色彩。立春与"kasumi"的组合,则是在持统朝颁历的大背景下,为缓和本土季节感与历法四季观之间的紧张关系,由宫廷歌人柿本人麻吕创造而出的。这一意象的诞生标志着和歌季节咏的成立,同时将立春的和训导入和歌的做法也对古代和歌泾渭分明的四季观的形成产生了重要的影响。
