随着全球范围内沉积盆地油气勘探程度的提高，用更有效的方法勘探油气藏已成为必然。作者引入系统论的方法，在研究了松辽盆地地球动力学背景、盆地构造、盆地沉积、热史等盆地流体动力条件的基础上提出了流体势及流体压力计算、新增剩余压力计算模型、古流体压力恢复等恢复古沉积环境及流体动力研究的计算模型。在动态研究油气藏方面做了初步探讨。     

基于准时制的时间成本双目标作业调度优化

提出了一种基于混合遗传算法的以生产周期和生产成本为优化目标的作业调度方法，该方法采用Giffler-Thompson启发式调度算法产生活动的调度，基于工序编码的染色体决定了工序调度的优先级，在启发式调度算法产生的冲突集合中，根据工序的优先级选择下一步安排加工的工序，混合遗传运算在全全局范围内搜索具有最优调度工序优先级的染色体，同时，在GifflerThompson的启发式算法中，采用了反向调度的策略，即从工件的交货期开始，先安排最后一道生产工序，然后依次安排前一道生产工序，直到工件的第一道工序调度完毕，形成一个完整的调度方案，在算法中，不仅考虑了工件的生产周期和多个工艺计划，而且考虑了库存费用和加工费用，设计了基于生产周期和生产成本的双目标适应度函数，算例结果表明该方法是可行的。

Cryptomelane（KxMn8-xO16）： Natural active octahedral molecular sieve（OMS-2）

The Xiangtan manganese deposit (XTM) used to be considered a supergene oxide manganese ore in South China. We reported a new identification of the naturally outcropping cryptomelane by examining the physical, chemical and structural features of the XTM supergene oxide manganese ore. The MnO2 content was over 90%, K2O more than 3%, and water from 2.2%-3.1% which is similar to one in zeolite. The cell parameters of the cryptomelane were given as a0 = 0.9974 nm, b0 = 0.2863 nm, c0 = 0.9693 nm and β= 91.47°. There was a larger pseduotetragonal tunnel in the natural cryptomelane that was formed by [MnO6] octahedral double chains with aperture of 0.462×0.466 nm2, filled with K cations resulting in some Mn3+ substituting for Mn4+ to balance the negative charges of structure. The finding is important not only for prospecting manganese resources in South China, but also in application of octahedral molecular sieve of natural cryptomelane as that developed in the tetragonal molecular sieve of natural zeolite o     

大型数据库中的高效序列模式增量式更新算法

提出一种称为FIMS（fast incremental mining of sequential patterns)的序列模式增量式更新算法，处理因数据库的更新而引起的序列模式的维护问题。主要思想是利用原先的序列模式挖掘结果，通过建立一个投影数据库来减少对整个数据库的扫描次数和侯选序列的生成，从而提高挖掘的效率。实验结果显示在更新数据量远小于整个数据库的大小时，FIMS算法的性能优于GSP算法4－7倍。

高速模拟钢质弹丸侵彻多层靶仿真

利用显式动力有限元程序对用37火炮发射的着靶速1300m／s左右钢弹侵彻大间隔多层A3薄钢靶板的过程进行了数值模拟，分析了弹速、弹重、弹形等影响因素对侵彻过程的作用规律，计算结果和实验结果得到了较好的吻合。研究表明，弹丸的比动能是衡量弹丸侵彻能力的重要参数，在一定的弹丸速度范围内，当弹靶材料和靶板结构固定时，弹丸的侵彻能力是由弹丸的比动能所决定的。     

N-terminal of L protein of vesicular stomatitis virus contains a new signal sequence

The L protein (241kD) of vesicular stomatitis virus (VSV) is the most important snbnnit of the replication complex. The existence of specific localization signal in the L protein was investigated by making recombinant constructs expressing truncated mutants of the L protein fused to green fluorescent protein (GFP) in transient transfection assays. The chimeric genes encoding varied N-terminal of L and GFP gene were put under the control of T7 promoter or CMV promoter. The fusion proteins were transiently expressed in BHK-21, COS-7, CHO or Hep G2 cells. When more than 120 residues were deleted or only 96 residues were kept on the N-terminal, the fusion proteins were shown to be distributed throughout the cells, cytoplasm and nucleus under the confocal microscope. However, other chimeric proteins with 120 or more amino acids were dotted and distributed in the perinuclear regions. And the fusion protein with 96—120 aa has the similar distribution. A thirteen-residue peptide QGYSFLHEVDKEA (108—120) was identified as localization signal, whose function would be absolutely distributed with the deficiency of D or V. Our results show that there is an independent localizing signal in N-terminal domain of L protein of VSV and this functional signal is conserved in different cell lines.
