A multi-channel polarimeter-interferometer has been developed on the Keda Torus eXperiment(KTX)for the study of equilibrium dynamics and internal magnetic fluctuations.A three-wave technique based on terahertz solid-state sources(-650 GHz)is applied for simultaneous measurements of electron density and Faraday rotation *** output power of the microwave source is 2 *** rotation effect using a rotating wave plate is tested with phase noise less than 0.8°,and the density phase noise is less than 0.9°.Measurement of Faraday rotation angle and density for discharges on KTX have demonstrated high sensitivity to internal MHD activities.

Jiaojiang sag in the East China Sea Basin is at the earlier exploration stage,where characterizing hydrocarbon generation of source rocks is important to understand oil-gas exploration *** geochemical and basin modeling analysis,hydrocarbon generation capacity and process of the Paleocene E_(1)y,E_(1)l and E_(1)m formations were *** show that E_(1)y and E_(1)l mudstones are high-quality source rocks with Type Ⅱ kerogen,which is dominated by both aquatic organisms and terrestrial higher plants deposited in sub-reduced environment.E_(1)m mudstone interbedded with thin carbonaceous mudstone and coal is poor-quality source rock with Type Ⅲ kerogen,whose organic matter was originated from terrestrial higher plants under oxidized *** by burial and maturity histories,E_(1)y and E_(1)l source rocks experienced two hydrocarbon generation stages,which took place in the Late Paleocene and in the Middle to Late Eocene,respectively,and had high hydrocarbon generation capacity with cumulative hydrocarbon volume of 363 and 328 mg/g,respectively.E_(1)m source rock only had one hydrocarbon generation process in the Late Eocene,which had low hydrocarbon generation capacity with cumulative hydrocarbon volume of only 24 mg/*** future oil-gas exploration in the Jiaojiang sag should focus on hydrocarbon generation center and select targets in the central uplift formed before the Miocene with high-quality traps.

A 10-channel Hα diagnostic system has been designed with the rapid response rate of 300 kHz, spatial resolution of about 40 mm, and overlap between adjacent channels of about 3%, and it has been implemented successfully on Keda Torus eXperiment(KTX), a newly constructed, reversed field pinch(RFP) experimental device at the University of Science and Technology of China(USTC). This diagnostic system is a very important tool for the initial KTX operations. It is compact,with an aperture slit replacing the traditional optical lens system. A flexural interference filter is designed to prevent the center wavelength from shifting too much as the increase of angle from vertical incidence. To eliminate the stray light,the interior of the system is covered with the black aluminum foil having a very high absorptivity. Using the Hαemission data, together with the profiles of electron temperature and density obtained from the Langmuir probe, the neutral density profiles have been calculated for KTX plasmas. The rapid response rate and good spatial resolution of this Hαdiagnostic system will be beneficial for many studies in RFP plasma physics.

西湖凹陷超压普遍发育,成因机制复杂,目前研究未见深入.从产生超压的主要因素入手,采用定性分析与定量计算相结合的方法,基于超压层段的测井响应特征、速度与垂直有效应力、沉积速率与孔隙度演化史、压力演化史与生烃强度史耦合的初步判断,再通过定量的计算综合分析了西湖凹陷超压的成因机制.研究表明:不均衡压实作用和生烃作用是西湖凹陷超压形成的主要机制,但在不同的区带有一定的差异.其中保俶斜坡带以不均衡压实作用为主,经过估算生烃作用贡献率为23%~57%,平均达到41%;而在中央背斜带超压形成机制有两种模式,大部分是以生烃作用为主的增压模式,贡献率为51%~78%;个别井位研究显示以不均衡压实作用为主的增压模式.在三潭深凹超压的形成中,不均衡压实作用与生烃作用相当,生烃作用增压稍强于不均衡压实作用增压,生烃作用的平均贡献率为60%左右.

使用密度泛函理论中的广义梯度近似对内掺Sc原子的graphene-Sc-graphene扩展三明治结构的几何结构、电子结构和储氢性能进行计算研究.计算发现：Sc原子位于单层石墨烯中六元环上方的结构具有较大的结合能,但小于固体Sc的内聚能实验值（3.90eV）,然而,当单个Sc原子或者多个Sc原子在双层石墨烯中间与底层相距2？时,Sc原子与基底的结合能增加到5eV以上,远远大于固体Sc的内聚能实验值（3.90eV）,因此相邻的Sc原子可以有效避免成簇.由此可见,三明治结构的形成明显增加了Sc原子与基底的结合强度,该结构可以进一步储氢来满足18电子规则而更加稳定,从而成为理想的新型储氢纳米材料.扩展三明治结构graphene-Sc-graphene的（2×3）单元中每个Sc原子最多可以吸附2个H_2分子,对H_2的平均吸附能分别为0.67eV和0.54eV,介于物理吸附和化学吸附（0.1~0.8eV）之间,因此该体系可以实现常温常压下对H_2的可逆吸附.由储氢机制分析可知：扩展三明治结构graphene-Sc-graphene主要通过Dewar-Kubas作用进行储氢,形成了π-δ-π型的电子结构.
