It including the pitch point electric current equation andthe return route voltage equation two parts, former pointed out that,regarding any pitch point (3 or 3 above legs points of intersection),flows in and flows out the pitch point various electric currents algebra and is zero, this is the constant condition request, latter pointed out, regarding any closed path, each part of loss of voltage algebra and is zero, this is the electrostatic field ring circuit theorem result, two constituted the complete system of equations.

它包括沥青点电流方程强大的回路电压方程由两部分组成，前者指出，对于任何节点（ 3层或3条以上的腿分的交汇点），流入和流出草地点不同电流代数和是为零，这是恒定的条件要求，后者指出，对于任何封闭道路，每部分的损失电压代数和为零，这是静电场的环形电路定理的结果，构成了两个完整的系统方程式。

In the Philippines, two electrical fires broke out in the Manila districts of Binondo and Sampaloc. In Binondo, 100 households were affected, including two deaths in the same family. In Sampaloc, 18 families were rendered homeless when their three-storey compound burned to the ground.

在菲律宾马尼拉的岷伦洛和三巴乐区，发生两起电线走火的火灾，在岷伦洛，火灾波及一百户人家，甚至有一个家庭造成两人丧命；在三巴乐区，一栋三层楼高的大厦的火灾、让18户住户无家可归。

In this paper, a cross-layer cooperative design is developed under the constraint of maximum transmission number per node in an uncoded two-hop relay network. Two-type simple single-relay adaptive cooperative protocols are proposed in order to exploit a combined spatial and time diversity.

摘要该文着重研究了无编码两跳中继网中考虑各节点的最大传输次数受限时的一种交互层协同设计，提出了两种类型的简单自适应中继协同策略以探索一种合并的空间分集与时间分集。

Secondly, the improved effects on aseismic behaviour of the frames strengthened with steel angels were discussed through the loading experimental study of two frame models on shacking table. The effects of different damage degree on the dynamic properties of strengthened structures were analysed emphatically.

其次通过两榀双跨四层模型振动台的两阶段受力试验研究，探讨了外包钢加固框架对结构整体抗震性能的改善效果，着重分析了不同破损程度对加固后结构动力特性的影响。

Photograph belongs to that class of laminated objects whose two leaves cannot be separated without destroying them both: the windowpane and the landscape, and why not: Good and Evil, desire and its object: dualities we can conceive but not perceive...

摄影是这样一种层合的玩意：它包含两个除非毁灭不可分割的层面，就像窗格子和窗格子里的风景，或者，有什么不可以：善与恶，欲望及其对象：类似这样我们可以承载却不能认知的两元对立。。。

In order to investigate the behaviors of composite frame composed of steel beams and steel concrete columns with angle lacings,the pseudo-static tests and pseudo-dynamic carthquake response tests of one third scale two-bay three-story composite frame,conducted as equivalent single degree of freedom sys- tem have been carried out.

为研究钢梁和角钢骨架混凝土柱组成的框架在荷载作用下的工作性能，进行了一榀1/3比例两跨三层S梁-SC柱组合框架模型在低周反复荷载作用和使用等效单自山度体系输入实际地震加速度记录两种加荷方式下的试验。

The stratospheric sudden warmings in 2002/2003 and 2003/2004 winters are analyzed using the daily four times ECMWF data. The differences of the average temperature and zonal wind are compared between these two winters, with calculating EP flux and the residual mean circulation.

利用ECMWF提供的60层气象场资料诊断分析了2002/2003和2003/2004年两个冬季的爆发性增温(stratospheric sudden warming， SSW)过程，比较了两次SSW期间高纬温度和纬向风的差异，计算了SSW期间的EP通量和剩余环流。

Meanwhile , numerical computation of aerodynamics is widely applied with the progress of computer , large quantities of relative paper has been presented . but at present , the relative literature about turbulence characteristics of plural vehicles running in row and passing maneuvers is very limited . pointing to the above difficulty , in this paper , numerical computation of turbulent - velocity field is studied while a sedan exceeding a tractor - trailer truck

本论文在对某国产轿车单车外流场的模拟地面边界层、车轮转动和侧向风载荷研究基础上，以及两辆轿车并列行驶、同向超车的稳态研究的基础上，选取了两种笛卡尔网格方案和四面体混合网格方案，开展某国产轿车超过某大型运输车的数值模拟研究。

Case of sample with 10cm length, weighing about 1/2 of two adjacent fabrics, put it between two adjacent fabrics (single-fibre cloth)each measuring 10 cm × 2cm, so as to make the sample thin layer, and sew roughly its four sides with white cotton sewing thread.

案件样品10厘米长，重约1 / 2的两个相邻的布料，把它与两个相邻的织物每个测量10厘米× 2厘米，从而使样本的薄层，并缝合大约4个双方以白色棉缝纫线。
