Accurate forecasting of the undecided population in a public opinion poll

The problem of pollsters is addressed which is to forecast accurately the final answers of the undecided respondents to the primary question in a public opinion poll. The task is viewed as a pattern‐recognition problem of correlating the answers of the respondents to the peripheral questions in the survey with their primary answers. The underlying pattern is determined with a supervised artificial neural network that is trained using the peripheral answers of the decided respondents whose primary answers are also known. With peripheral answers as inputs, the trained network outputs the most probable primary response of an undecided respondent. For a poll conducted to determine the approval rating of the (former) Philippine president, J. E. Estrada in December 1999 and March 2000, the trained network predicted with a 95% success rate the direct responses of a test population that consists of 24.57% of the decided population who were excluded in the network training set. For the undecided population (22.67% of December respondents; 23.67% of March respondents), the network predicted a final response distribution that is consistent with the approval/disapproval ratio of the decided population.

用聚砜超滤膜处理含油污水的实验研究

主要研究了处理含油污水用的聚砜超滤膜的分离、透过性能与制膜液配方(聚合物浓度、溶剂及添加剂的种类和配比)之间的关系.确定了最佳的制膜液配比.所制得的膜在操作压力为0.36MPa(绝)时,其纯水通量为750L/(m~2·h).处理含石油类36～100ppm的含油污水时透过液通量达130～355L/(m~2·h).透过液中含油量降至10ppm以下.透过液中的石油类、悬浮物及色度等都基本上达到国家排放标准及油田注水用标准.

THE TRANSFER BEHAVIOUR OF SOME CATIONS AT WATER／NITROBENZENE INTERFACE BY SEMIDIFFERENTIAL CYCLIC VOLTAMMETRY

The transfer of Sr~(2+) and Ba~(2+) ion, facilitated by 18-Crown-6 present in the aqueous phase, and of succinylcholine ion at w/nb interface were investigated by semi-differential cyclic voltammetry. A good polarographic curve of succinylcholine ion dissolved in water was obtained in the system of 0.01 mol/l LiCl (w)——0.01 mol/l TBATPB (nb). The peak current is directly proportional to the concentration of SC~(2+) ion. It can be used for the determination of SC and the detection limit is 1.05×10~(-5) mol/l.The apparent D~w and D~(nb) have been estimated. The transfer of Sr~(2+) and of Ba~(2+) at the interface are facilitated by 18-Crown-6 present in the aqueous phase and the peak current is directly proportional to the concentration of 18-Crown-6 in water. This method can be used for the determination of the complexing agent and for the stability constant of the complex formed in the aqueous phase.All the experimental results are in keeping with the theoretical.     

济源凹陷油源追踪及烃类垂直运移作用

济源凹陷为一中、新生代复合型断陷．下第三系原油为轻质、低硫原油，与下伏中生界（Ｔｔ－Ｊ２）湖沼相生油岩抽提物具有同源性，而与下第三系泥岩抽提物回然相异。后邓断裂是烃类垂直运移的良好通道，中生界生成的烃类沿断裂经过了约３０００－４０００ｍ的垂直运移而聚集成芷。长距离的垂直运移造成了原油中ｒ－蜡烷的富集，作为运移通道的断裂发育时间、规模等控制了浅层油芷的分布．
