结构

After knowing the structure nature frequency, optimize the structure, such as disposal the point of support, reduce the number of elbow, change the thickness of pipe, setting the dilatant and so on, which offer a basic to avoid resonance.

当知道结构固有频率后，便可以通过优化结构，例如重新布置支点、减少弯头数、改变管的厚度、设置膨胀圈等方法，改变结构的固有频率，为避开共振频率打下基础。

A direct correspondence is shown between MTS fuzzy model with the determining consequence structures and the radial basis function networks,.

该方法表明具有确定后件结构的 MTS模糊模型与径向基函数网络之间有一种直接对应关系，基于这种对应，我们可把 MTS模型的前件结构确定和后件结构辨识分开，利用径向基函数网络的学习特性和其它学习算法相结合来得到模糊模型。

The problem of how the coherent structures in the wall region of a turbulent boundary layer could be excited by the disturbances from the outer region was investigated by using direct numerical simulation method.

应用直接数值模拟的方法，研究了湍流边界层近壁区由于外区扰动的作用而导致相干结构产生的问题·结果表明：在湍流边界层近壁区的上边界存在的速度扰动，可以在近壁区内激发出相干结构，从而完善了单个相干结构的理论模型

For example, dissemination in the geological material and function to the underground structure by blasting earthquake wave often cause the structure damage in varying degree, even appears serious consequence of the structure disarrangement .

爆破公害对环境的影响日显突出，如爆破地震波在地质材料中的传播及对地下结构的作用，往往引起结构不同程度的损伤，甚至出现结构破坏的严重后果，引发各种民事纠纷，阻碍了爆破事业的发展。

There are a great many L-shape structures in modern designing, which induce stress concentration and singularity. The dependence of the discretization error on the mesh refinement of such structures of fillet and connection point is of particular evidence.

结构设计中广泛存在L-型结构往往导致应力集中和应力奇异性，有限元离散过程很大程度上影响了L-型结构角点附件的位移和应力数值解精度。

Some studies indicate that the industry concentration ratio is too low and the scale of firms is too small which is bad for the improvement of efficiency,but others has the opposite opinions that China steel industry has the characteristic of diseconomy of scale and there is not an obvious relation between efficiency and market structure.

关于市场结构和经济绩效之间的关系，概括起来主要有市场力量假说和效率结构假说。不同的假说意味着不同的政策含义。确定我国钢铁行业规模效率特征和市场结构与企业效率的关系是实施正确产业政策的基础，具有重要意义。

In a word, because multiple social subjects dissatisfy their extant resource structure, they are to take action to enhance their stock of resource accordingly.

而社会资源结构的变迁又推动了社会主体关系结构和社会规则结构发生变迁。

The principle and design method of vibration energy dissipation and structural control are introduced.

介绍了结构控制和消能减振技术的减振机理和减振设计方法，对不同结构构造的粘滞流体阻尼器的耗能原理进行了研究，研制出了一种性能稳定的双出杆型工程结构减振粘滞流体阻尼器。

Heller—Knight Model stressed the balance of trades effect in the currency structure of foreign exchange reserves decision. Dooly model shows the trade flows, the debt payment and the exchange arrangements will all affects the currency structure of foreign exchange reserves. There is some logic to each of these three models, but are not comprehensive enough.

资产组合理论强调货币的收益与风险在安排外汇储备币种结构中的作用，海勒——奈特模型强调贸易收支在决定外汇储备币种结构中的作用，杜利模型则将影响外汇储备币种结构的因素扩大为贸易流量、外债支付及汇率安排三个因素。

Followed from the currency reserve structure to optimize the structure of the main factors affecting research, this paper introduces the three theoretical models: Asset Portfolio Theory, Heller—Knight Model and Dooly Model. Portfolio Theory stresses the returns and risks in arranging the structure of foreign exchange reserves.

紧接着从优化储备货币结构入手，对影响结构的几个主要因素进行了研究，并介绍了外汇储备币种结构选择的三大理论模型，即资产组合理论、海勒——奈特模型和杜利模型。
