RAPD molecular markers and ITS sequence comparisons were used to establish the relationship between Boletus appendiculatus fruit bodies collected from Qingyuan, zhejiang Province, and mycelium isolated from the fruit body tissue. RAPD analysis of extracted genomic DNA revealed that B. appendiculatus fruit bodies (fb) and the isolated fungal mycelium (mb) formed a single cluster with a Dice coefficient value of 0.92. Comparison of ITS sequences from these samples showed that base sequences and fragment lengths were identical, thereby confirming that the fungal mycelium isolated from B. appendiculatus fruit bodies was the vegetative form of the mushroom. Our data suggest that RAPD fingerprinting combined with ITS sequence comparisons constitute an effective and feasible method for identifying mycelium isolated from ectomycorrhizal fungi.

Discrete ion-pair complexes [Ln(EDBP)2(DME)Na(DME)3] [Ln=Er (1), Yb (2), Sm (3)] have been synthesized by the reaction between sodium salt of 2,2'-ethylidene-bis(4,6-di-tert-butylphenol)(EDBPH2) and Ln(BH4)3·3THF (Ln=Er, Yb, Sm) followed by centrifugation and recrystalization. The complexes were characterized by elemental analysis and FT-IR, and the bonding model of these compounds was confirmed by X-ray single crystal diffraction for complex 1. It was found that four O atoms in two biphenol ligands as well as two O atoms in one ethylene glycol dimethyl ether (DME) molecule connect to the center rare earth metal atom, while sodium exists as counterpart cation to balance the charge. Complexes 1―3 can all be used as single component initiators for the ring-opening polymerization of ε-caprolactone.

This paper introduces the environmental monitoring results of γ dose rate levels during the past years from 1992 to 2004 at the ambient areas of QNPP（Qinshan Nuclear Power Plants）Base in northeastern zhejiang *** data indicates that the gamma dose rates of the past 13 years,acquired at 5 monitoring sites（the Top of Qinshan Hill,the Frontier Monitoring Station,the Primary School of Qinshan Town,Qinlian Village and Cai Chenmen Village）located within 2.5 km far from QNPP Base,range from 82 to 113 nGy/h,and the average value is 96 nGy/*** values are the same level as the background value 93 nGy/h considering statistical fluctuation which was obtained at these sites before the operation of QNPP,and are a little lower than the mean value 101 nGy/h measured at the reference site（hangzhou）from 2002 to 2004,and all of γ external radiation data mentioned above is measured using HPIC（High Pressure Ionization Chamber）.On the other hand,within the distance of 50 km from the Base,the results of the TLD cumulative dose rate is 90 nGy/h,and also lower than the background value 111 nGy/h,this mainly because the placed height of TLD dosimeter was changed from 1.5m to more than 2m.

在许多地区,前期降雨条件对滑坡的发生有重大影响,前期有效降雨量是滑坡预报的一个重要参数。基于累积滑坡频度-降雨量分形关系导出了一种新的计算前期有效降雨量的方法。在这个方法中,降雨衰减系数是由给定区域内引发滑坡的累积降雨阀值随观测时段天数变化的标度指数所决定,滑坡前每天降雨对总有效雨量的贡献并非是独立的,前i天降雨的衰减过程与前i-1天的降雨相关联。
