A fragment constant QSAR model for evaluating the EC50 values of organic chemicals to Daphnia magna.

The quantitative relationship between the median effective concentration (EC50) of organic chemicals to Daphnia magna and the number of molecular fragments was investigated based on experimental EC50 values for 217 chemicals derived from the literature. A fragment constant model was developed based on a multivariate linear regression between the number of fragments and the logarithmically transformed reciprocal values of EC50. Functional correction factors were introduced into the model. The model was verified using an independent set of randomly selected data. The mean residual of the final model was 0.4 log-units. The robustness of the model was discussed based on the results of three jackknife tests.

云南地热资源──以腾冲地区为重点进行解剖

位于中国西南部的云南省,具有丰富的地热资源。这些地热资源大致可分为三类：①高温水热系统;②中-低温水热系统;③“隐伏型”地热资源。根据地热背景（大地构造和热流）和热显示,本研究首先对各构造单元中的地热资源进行了评价,然后重点分析了腾冲地热区的地热资源及其热源和水源的成因。研究结果表明．腾冲地热田形成于板块的碰撞带,其丰富的高温水热系统地热资源的主要形成机制是：①高温热能来自地幔以及地壳中的熔融岩浆囊;②丰富的大气降水补给──大气降水通过断层（特别是活断层）的循环并与少量来自地球内部的水混合。本文提供的资料表明,腾冲地热资源具有开发利用价值──发电和发展旅游业,在东川一个旧一线（东经103°20′）以西地区,中─低温地热资源一般钻进深度不到1000m就能开发出来。
