With the construction of water transfer projects， shield tunnels have been widely used. Long distance water transfer tunnels inevitably traverse sections of poor geology and potential uneven settlement may occur in shield tunnels under non-uniform geology. As the main load-bearing structure， the current assembled outer lining mainly uses diagonal bolted joints. A reasonable modelling of the diagonal bolted joints and an analysis of their mechanical behavior under uneven settlement is of great importance for the analysis of the longitudinal stability of tunnels. In this paper， the mechanical performance of inclined bolted joints under the action of external forces is investigated. The distribution of axial force and bending moment of the inclined bolts under different operating conditions is studied， the bolts are simulated using the generalized displacement method of buried beams， and a numerical simulation method is established considering the interpolation of the corner displacement. By comparing the finite element analysis results with the test results， it is concluded that the interpolation of the corner displacement of the bolt has a significant influence on the numerical simulation， and it will generate a certain bending stress under uneven settlement， which provides a reference for engineering design.

在HL-2.装置上发展了一套用于边界和刮削层(SOL)中等离子体涨落测量的喷气成像诊断(GPI)系统，该诊断测量范围在弱场侧中平面附近，测量范围大小为160mm×160mm，极向-径向的空间分辨能力为2.5mm×2.5mm，时间分辨能力3～10μs。通过与朗缪尔探针数据的对比，验证了GPI诊断可以得到高时空分辨率的等离子体密度扰动数据。在此基础上，发展了分析GPI实验数据的椭圆拟合算法，从而定量研究丝状结构(blob)运动，分别计算得到了blob位置、空间尺度(包括极向、径向特征长度)及运动速度等关键参数，blob空间尺度的演化验证了极向剪切流对大尺度湍流结构的拉伸及剪切分裂作用，且观察到极向运动由边界径向电场驱动的Er×B极向流主导。而blob径向速度向外，符合blob内部极向方向的电荷分离驱动了blob径向运动的分析。结果验证了椭圆拟合算法在GPI数据分析中的重要应用，为将来研究blob的演化过程提供了重要的测量分析方法和实验基础。

A number of lead-zinc sulphide deposits have been discovered in recent years in dolo- mitic rocks of the Upper Sinian Dengying Formation in the Dadu River valley region, Sichuan Province, China. The lead-zinc mineralization is closely associated with a black siliceous exhalite that has been traced over 50 km of strike. This makes Dadu River valley the most extensive stratiform non-ferrous sulphide horizon having been discovered to date in China. In a previous study by the first author (LIN), these deposits were recognised as belonging to the broad spectrum of lead-zinc sedimentary exhala- tive (SEDEX) deposits. In this paper, seismites and seismogenetic structures occurring in close association with the Dadu River valley mineralized zone are described. The close spatial and temporal relationship between the seismites and mineralization provides strong evidence for the hypothesis that the lead-zinc SEDEX deposits formed in direct response to earthquake activities around the Sinian-Cambrian boundary. The earthquakes are postulated to be an effective dynamic mechanism for triggering the upward migration of deep circulating ore fluids along synsedimentary growth faults and their exhalation onto the sea-floor to form the extensive deposits of stratiform lead-zinc sulphide ore.

针对煤矿井下无轨胶轮车尾气污染严重，无法满足非道路国Ⅳ排放标准的问题，为其设计了一种新型复合式尾气净化装置并进行了试验验证。首先，设计了由“废气再循环（Exhaust Gas Recirculation,EGR）+氧化催化器（Diesel Oxidation Catalyst,DOC）+催化型颗粒捕集器（Catalyst Diesel Particulate Filter,CDPF）+防爆水冷结构”组成的尾气净化系统；接着，利用GT-Power仿真软件建立了催化器模型，得到了排气参数对DOC催化反应的影响规律；在此基础上，针对TDE6105DZLQFB02.道路国Ⅲ防爆柴油机研制了尾气净化装置并进行了柴油机性能及排放试验。试验结果表明：加装尾气净化装置后，试验车辆在不同工况下，尾气中CO、HC、NOx和PM的净化效率分别达到了96.8%、50.95%、2..5%和95.2.，可满足非道路国Ⅳ排放法规限值。

The planar cubic hybrid hyperbolic polynomial curves and cubic H Bézier curves are presented. The conditions leading to inflection points and singularities (cusps and loops) are investigated and the shape of these curves is classified. The conclusions enable us to detect inflection points and singularities and get an idea of how to preserve the fair shape when designing such curves.

How to determine the earth’s external gravity field with the accuracy of O(T2. by making use of GPS data and gravity values measured on the earth’s surface is dealt with in this paper. There are two main steps: to extend these measured values on the earth’s surface onto the reference ellipsoid at first and then to seek for the integral solution of the external Neumann problem outside the ellipsoid. In addition, the corresponding judging criteria of accuracy to solve the GPS-gravity boundary value problem are established. The integral solution given in the paper not only contains all frequency-spectral information of the gravity field with the accuracy of O(T 2., but is also easily computed. In fact, the solution has great significance for both theory and prac- tice.

关键词： Neumann boundary value problem, integral solution, gravity disturbance.
