Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.

构造沉降是控制层序几何形态，充填叠置方式、演化及沉积体系分布的最重要因素：凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成；受断层控制，层序外部形态有箱状-楔形、楔形-席状披覆型，边界终止方式有双断终止型、单断终止超覆型；不同构造演化阶段层序内部充填的沉积体系各具特征，初始断陷阶段的SQ1沉积冲积层序，强烈断陷阶段的SQ2-SQ4充填湖相层序，晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积；同沉积断层陡坡带沉降迅速、可容纳空间快速增长，是凹陷的沉积和沉降中心，断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。

Structure characteristics of laminated composites in nature such as nacre are described briefly in this paper.

以贝壳珍珠层为例，简要介绍了天然叠层状生物材料的结构特征，并针对叠层状仿生材料的设计原理、制备技术及其研究现状等方面加以综述。

It is in accordance with the southward overthrust nappe acting time of South Tianshan orogenic belt.

前渊带以巨厚的浊积岩为特征，在上石炭统上部-下二叠统隆林阶中部台地相地层之上沉积有浊积岩的地质事实表明，前渊带在隆林晚期至中二叠世栖霞期不断向南迁移，这与南天山造山带当时的向南逆掩推覆活动是一致的。

Some of the main features of the Qilian belt are similar to those in western China, such as fault-related folds and thrust systems developed in thrust belts, which formed during the Himalayan orogenesis.

由於不同性质盆地的叠合，冲断带走向方向地层组成变化大；冲断带的分段性受控於古构造格局；主要发育横向叠置的多重冲断构造体系。

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

This paper presents a stability criterion for design iterative learning controller. From the criterion,one can change the design problem into finding a positive definite discrete matrix kernel. It has been shown that what kind of variable can be controlled by the iterative learning,(2) and what kind of filter can be included into the controller.

摘要提出了一种针对自学习控制的稳定性判据，应用这一稳定性判据将自学习控制器的设计转化为寻找正定离散矩阵核，从而回答了两个问题，其一什么样的量可以通过自学习叠代加以控制，其二学习叠代中什么样的滤波环节的引入不会影响学习收敛性。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
