莺－琼盆地YA13－1气田热流体活动与有机／无机成岩响应

根据钻井中途测试（ＤＳＴ）、重复地层测试（ＲＦＴ）、镜质体反射率（Ｒ０）、流体包裹体分析和粘土矿物Ｘ射线衍射全定量分析等综合研究发现，莺－琼盆地ＹＡ１３－１气田存在４期热流体活动；南侧的崖南地区和西侧的莺歌海盆地是其两个重要的热流体物质源和动力源；多期热流体活动在ＹＡ１３－１地区不仅造成热异常和物质迁移，而且还引起了不同的有机／无机成岩响应，如骨架颗粒的多期溶蚀作用、至少两期的次生加大作用、粘土矿物转化和有机质热成熟作用异常。第二、第三期热流体因出溶作用形成ＹＡ１３－１气田大规模的天然气聚集。

Time-delay control of structures

Time-delay causes unsynchronized application of the control forces which may not only degrade the performance of the control system but also even induce instability to the dynamic system. Time-delay control algorithm is developed in this paper to solve this practical problem. The control system is first formulated in discrete-time form. In the presence of time-delay, the motion equation of the discrete-time control system remains a difference equation which can be transformed into first-order difference equation by augmenting the state variables. Optimal time-delay control algorithm is derived based on the augmented system. The time-delay control forces are simply generated from the time-delay states multiplied by the constant feedback gain. Numerical simulation is illustrated to verify the feasibility of the proposed control algorithm. Since time-delay effect is incorporated in the mathematical model for the structural control system throughout the derivation of the proposed algorithm, system performance and dynamic stability are guaranteed.

台湾琉球地区Lg波的震相特征

根据浙闽台站记录的台湾琉球近震资料，研究了该区Ｌｇ波的组成及各震相的基本特征。研究表明，该区Ｌｇ波由多个速度不同的波群组成，在Ｌｇ１和Ｌｇ２两种波中可以分出Ｌｇ′１、Ｌｇ″１；和Ｌｇ′２、Ｌｇ″２四种震相，不同震区各震相的记录特征明显不同，鲜明地反映出地壳结构由大陆型向海洋型过渡的特点。此外，还对波列中的未知震相、影响震相记录特征的其它因素，以及震相标注和Ｌｇ波走时表等问题进行了讨论。

钢梁阻尼器的最佳延性率及其控制

基于双线性和三线性的力－位移滞回线假设，导出了钢梁阻尼器隔震系统等效阻尼比与阻尼器延性率的关系；为了获得大阻尼比隔震系统，以尽量减小隔震系统的地震反应，求得了使系统阻尼比为最大的阻尼器相应延性率（即最佳延性率）所需满足的条件；给出了在给定地震地面运动输入条件下，使系统阻尼器变形位移达到最佳延性率的阻尼器初始刚度和屈服位移的确定方法。     

Organic Acid Derivatization Techniques Applied to Petroleum Hydrocarbon Transformations in Subsurface Environments

Evidence for the natural microbial remediation of subsurface fuel contamination situations should include identification and analysis of transformation or degradation products. In this way. u mass balance between fuel constituents and end products may be approached to monitor cleanup progress. Application of advanced organic acid metabolite derivatization techniques to several known sites of organic compounds and fuel mixture contamination provide valuable information on the pathways and progress of microbial transformation. Good correlation between observed metabolites and transformation pathways of aromatic fuel constituents were observed at the sites.
