Amateur archaeologist semir osmanagic recently announced that he has uncovered proof that a four - sided hill in the town of visoko , bosnia , is an ancient manmade structure 业余考古学家西玛尔最近宣称，他已经找到证据证明在波斯尼亚的维索克镇里的一座四边形小山丘是古老的人工建筑。
Because of the influence of harmonic , traditional power triangle ca n ' t be applied in variable frequency speed regulation system , this text proof the accuracy of the power quadrangle 由于谐波的影响，传统的功率三角形已经不能适用于变频调速系统，本文证明了功率四边形的正确性。
In order to deal with different kinds of building shapes , body - fitted quadrilateral grids are arranged in the inner domain and rectangle girds in the outer domain 为适应不同建筑体型的需要，本文提出在内层区域布置贴体的任意四边形网格，而在外围区域布置直角坐标矩形网格的分层网格离散模式。
By using the multiple spanning tree ( mst ) protocol , if one link is down , the network traffic will go to another link automatically and this is transparent to the users 为了提供一个既可靠又稳定的网络服务，我们把千兆位以太网络设置成一个四边形，并利用multiplespanningtree ( mst )协议作传输。
The grid auto - generation of the inner and outer domains is carried out by generating a small number of quadrilateral super elements and each super element then further discretized into smaller elements 内、外两层区域的网格自动生成，先将各区域划分为数量较少的四边形超单元，然后对各超单元逐个剖分。
The floor was sand . before a big fire lay captain smollett ; and in a far corner , only duskily flickered over by the blaze , i beheld great heaps of coin and quadrilaterals built of bars of gold 斯莫列特船长躺在一大堆火前闪烁的火光隐约照到远处的一个角落，我看见那里有几大堆金币银币和架成四边形的金条。
The swirls of green were revealed by hubble ' s ultraviolet and visible - light detectors . they are hydrogen and sulfur gases heated by intense ultraviolet radiation from the trapezium ' s stars 那绿色的漩涡是由哈勃的紫外和可见光探测器所展示出来的。它们是被“猎户座四边形”发出的强烈紫外线加热的氢和硫的气体。
Based on 4 - nodes quadrilateral mixed interpolation shell element and total lagrange formulations , elastic - plastic finite element analysis was made for the mechanical behavior of circular radial slotted plane rupture discs 摘要基于t . l .列式，采用四边形四结点混合壳元对平板透缝爆破片的力学响应进行了弹塑性有限元分析。
The shape of cross section of gravity dams under basic loads was optimized from an initial quadrilateral region with the stability of dam bodies against sliding and the tensile stress in dam heels taken as restraints 以四边形为初始域，以重力坝的稳定和坝踵拉应力为约束条件，对基本荷载作用下的重力坝基本断面形状进行优化。
According to traditional power triangle ( the square of the active power , reactive power and apparent power form the relation of the right triangles ) , put forward a new electrician ' s theories of power quadrangle 基于传统的功率三角形(即有功功率，无功功率，和视在功率三者的平方成直角三角形的关系) ，提出了功率四边形这种新的电工理论。
