过程综合混合整数非线性规划的罚函数—凑整算法

针对过程系统最优综合的混合整数非线性规划（ＭＩＮＬＰ）模型，提出了一个整型变量松弛的新算法－罚函数－凑整算法，只需求解ＮＬＰ问题就可得到过程系统最优综合ＭＩＮＬＰ问题的解。典型算例表明，计算时间和算法的有效性都优于传统的ＭＩＮＬＰ分解算法。

A modified model for dynamic properties of visual receptive field

The extended Gabor function model for visual receptive field ( RF) was modified by substituting the term related to time with two-order integral kernel of F function to generate a new model called modified Gabor function model of RF. A set of the modified Gabor models (MGM) can present the major spatiotemporal properties of neuronal receplive fields at different levels of primary visual pathway. The transient responses, dynamic properties of RF simulated by MGM, are in good agreement with the observations in electrophysiological experiments.

An initial discussion on major controlling factors on formation of coal-formed large-medium gas fields

The so-called "large-medium gas field" means a gas field with proven reserves equal to or larger than 100×108 m3.Up to 1997,23 coal-formed great-medium fields are discovered in China,excluding two in Taiwan Province.Their proven reserves take 50.9% in total natural gas reserves.Therefore,the coal-formed great-medium gas field plays a decisive role in natural gas reserves and the study of their controlling factors is very important both in theory and in practice.There are six major controlling factors on the formation of coal-formed large-medium gas fields:(ⅰ) The generating center of coal-formed gas and its surrounding area; (ⅱ) low potential area; (ⅲ) late pool-forming period; (ⅳ) traps related to the paleo-uplifits in coal-formed gas area; (ⅴ) above or between abnormally pressured compartments; (ⅵ) faulted traps related to coal-bed.

陶枣煤田岩溶发育的空间规律及其对水文地质条件的制约作用

在充分了解陶枣煤田地层、构造、地表水系等特征的基础上，通过现场调研、实地测量、已有资料的统计分析，提出了该煤田内碳酸盐岩的岩溶发育具有明显的块、段立体特征，即在平面上具有分块，在垂直上则有分段的规律性，这种块，段岩溶发育规律控制了陶枣煤田岩溶的水文地质条件。最后对岩溶如此规律发育的原因进行了探讨。
