Along the low-angle overthrust Early Permian marble and Early Triassic sandy slate were thrust southward over Paleocene-Eocene purplish red conglomerate of the Paleocene-Eocene Fenghuoshan Group and brick-red sandy conglomerate of the Oligocene Yaxicuo Group, forming many klippen of varying scales, and thick fault brecci.

沿低角度逆冲断层，早二叠世大理岩和早三叠世砂板岩自北向南逆冲推覆于古新统—始新统风火山群紫红色砾岩和渐新世砖红色砂砾岩之上，形成大量不同规模的飞来峰；沿主逆冲断层发育厚层断层角砾岩与断层泥，局部形成碳酸盐质糜棱岩。

To overcome color degradation because of the presence of silver, the surface of compound samples were covered a bit of sodium laurate to modify surface activities. The chromatism and lipophilic degree had also been examined.

为了克服由于Ag存在产生的变色问题，采用在复合试样表面包覆一层月桂酸钠来进行表面改性并测量色差和亲油化度。

结果表明：纳米铝粒子表面被聚合物层包覆，实现了微观尺度上的复合。

According to the structural analysis, these have been divided into several composed types such as bedding ductile shear zone, Alpinotype folds, Mt Jura-type folds, transition shear zone, obduction nappe structure and horst-graben structure.

通过构造解析划分出了顺层韧性剪切带、尔卑斯式褶皱、罗山式褶皱、渡性剪切带、冲推覆构造及地垒－堑式构造等组合类型。

An early rift sequence is overlain by a large Late Cretaceous delta, which culminates with the mid-Campanian Rakopi Formation coal measures.

Adopting the model of uniform load and triangular load separately,MRFs of different story numbers and bay numbers are analyzed by static Pushover analytical method,and the global capacity envelopes are obtained.Then,through a method for establishing the inelastic demand spectrum of design intensity and rare intensity based on elastic spectrum of seismic design code for buildings,the structural target displacement of design intensity and rare intensity are estimated by improved capacity spectrum method.The corresponding structural ductility reduction factor,the overstrength factor,the structural influencing coefficient and displacement amplification factor are determined.

分别采用水平均匀分布力和倒三角分布力加载模式对不同层数和跨数的钢框架结构进行了静力推覆分析，并得到了结构的能力曲线，在此基础上，应用改进的能力谱法，以规范反应谱为基础建立设防烈度和罕遇烈度下的弹塑性需求谱，确定出结构在设防烈度和罕遇烈度下的目标位移，进而求解出结构的延性折减系数、超强系数、结构影响系数和位移放大系数等参数；同时，分析了不同加载模式、层数和跨数等对各系数的影响。
