抚仙湖面源污染特征及其防治对策

根据抚仙湖径流区污染物负荷量的调查结果,抚仙湖水污染特征以面源为主,面源入湖水量占98%,TP占81.4%,TN占85.9%,因此控制面源是保护抚仙湖的关键。提出了防治抚仙湖面源污染的生态治理及工程治理对策。     

我国生态工业园区稳定性的调研报告

作为可持续发展的重要实践工具，生态工业园（EIPs）建设得到快速推进的同时，也由于多方面存在的影响因素制约，使园区面临“不稳定”风险．本调研报告通过专家调查和全国范围内的统计调查确认了“技术充足，政府支持，行业多样，核心组员，成员沟通”等5个影响因素对我国生态工业园区稳定发展具有显著影响，并对数据结果做了进一步的讨论，提出了相应的政策建设。     

Detection of low-grade mosaicism in fetal cells isolated from maternal blood

Recovering and analysing fetal erythrocytes from maternal blood is being pursued for non-invasive prenatal genetic diagnosis. We report the observation of 46, XY/47, XXY mosaicism in fetal cells from a woman whose first-trimester chorionic villus sampling (CVS) initially showed only 46, XY. Only after exhaustive (500 cells) analysis were four XXY cells found in cultured villi.

升流式厌氧污泥床筛分强度数学模型研究

通过对升流式厌氧污泥床的流动分析，提出了用离散数Ｄ定量地表示筛分强度。通过实验和回归分析，建立了Ｄ与水力负荷（Ｌ）和沼气沼气容积产量（Ｇ）的数学关系：Ｄ＝０．００３３Ｌ＋０．０４５Ｇ＋０．０７３。当Ｄ在０．０８８－０．０９５之间，用生活污水作基质，成功地培养出了颗粒污泥。     

The nature of the redshift and directly observed quasar statistics

The nature of the cosmic redshift is one of the most fundamental questions in modern science. Hubble's discovery of the apparent Expansion of the Universe is derived from observations on a small number of galaxies at very low redshifts. Today, quasar redshifts have a range more than 1000 times greater than those in Hubble's sample, and represent more than 100 times as many objects. A recent comprehensive compilation of published measurements provides the basis for a study indicating that quasar observations are not in good agreement with the original predictions of the Expanding Universe theory, but are well fit by the predictions of an alternative theory having fewer adjustable parameters.     

First-trimester prenatal diagnosis of severe alpha-thalassemia

By means of chorion biopsy together with restriction endonuclease analysis of fetal DNA, first trimester diagnoses were successfully made in 33 fetuses at risk for Bart's hydrops fetalis. Seven pregnancies with Hb H or hydrops fetalis were therapeutically terminated before 4 months of gestation. Of the 26 pregnancies intended to continue, 18 have come to term with normal deliveries; one with threatened abortion was terminated at the end of the first trimester and, seven are progresssing normally.
