And in 1981, in "Raiders of the Lost Ark," that approach was so old-fashioned it looked new. In the 27 years since, practically every action filmmaker has tried to tap into the movie's quasi-mystical kinetic power: the pace had to be blindingly fast; the stunts insanely elaborate, the villainy extra-villainous; the hero's attitude blithe, insouciant, almost sociopathically cool.

1981年《法柜奇兵》的处理方式，就做得老派而历久弥新。27年来，实际上每一位动作片导演都尝试充分利用这部电影有点神秘的活动能量：速度必须快到令人眼花撩乱；特技动作必须疯狂复杂；为非作歹耍坏到不行；英雄的态度乐天、逍遥、酷到几乎反社会的程度。

There are millions of population migrations from the rural areas to the urban areas, but they are instable and quasi-urbanization.

虽然有数以千万计的的乡村—城市的流动人口，但不稳定，呈准城市化状态。

The finiteelements satisfied the integral condition are quasi-conforming element,generalized conforming element,and elements constructed by 2 set parametermethod,and they are equivalent in some sense,and all converge to constantstrain.

满足这种条件的有限元有拟协调元、广义协调元和双参数法构造的单元，在一定意义上它们是等价的，并都收敛到常应变。

Based on these studies, this paper argues that the EU is a highly integrationist regional organization with supranational features mainly and the combination in characteristics of both supranational and intergovernmental, or to be more exact, quasi-federal polity.

基于这种微观与宏观相结合的研究，本文认为，欧洲联盟是一个以超国家性质为主要特征的、超国家与政府间性质并存的、高度一体化的区域性经济政治组织，或准联邦实体。

In particular, Single-wall carbon nanotubes have attracted great interest due to their quasi-one-dimensional structure and unique electronic properties.

其中单壁碳纳米管以其准—维的分子结构和奇特的电学性能备受瞩目。

Solid quasi-fluid state, which is similar to liquid and exists in surface and interior of solid, is a new kind of state besides gas, liquid, solid and liquid crystal.

固体"类流态"是固体表面及其内部存在的一种类似于流体的状态，是除气、液、固、液晶之外的一种新的物质存在的形式。

On the basis of the framework of internal variable quasi-thermodynamics, the relationship between viscosity theory and plasticity theory is studied.

在内变量准热力学的框架内分析黏性理论和塑性理论之间的关系。

First, an octree of the point cloudis constructed with a volume-based refinement method, and then the volume ofthe point-sampled surface can be estimated by using quasi-Monte Carlo methods.Based on the Cauchy-Crofton formula, the area of the point-sampled surface isalso calculated by counting the number of intersection points between the pointcloud and a set of uniformly distributed lines generated with low-discrepancysequences.

基于体积加细的方法构造点模型的八叉树，再利用拟蒙特卡罗方法完成体积计算；基于Cauchy-Crofton公式，通过计算点模型与均匀分布的直线集合的交点个数，完成面积计算。

Secondly, Dynamic and quasi-static state mechanical properties experiments of hardened 45 steel and Fe-36Ni invar alloy are performed by Split Hopkinson Pressure Bar and electronic universal testing machine, the dynamic mechanical properties under high temperatures and high strain rates are obtained.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
