环形

So roundabouts may be a small reason why America's roads are slowly getting safer.

因此，环形路可能是美国道路安全率缓慢上升的因素之一。

But the signal controls on the roundabouts put in practice only for a little time. It is serious lack of relative theory up to now.

但环形交叉口进行信号控制在实践中应用时间较短，相应的理论研究较为缺乏。

The Theoretical Models of Roundabouts ′ Capacity are closely connected with the road and traffic flow′s conditions.

本文对我国国道上环形交叉口道路及交通特性进行了分析研究。

A 2001 study by the IIHS found that roundabouts have 80% fewer crashes with injuries than ordinary intersections.

公路安全保险学会2001年的一份研究发现，在环形路上，致人受伤的交通事故发生率要比普通交叉道路低80%。

The arguments for roundabouts are strong.

关于环形路的争论一直很激烈。

We lose far more roundabouts that could have been built, because of city councils or a trucking company, says Mr Walsh.

维尔士说，&要不是因为市议会和汽车货运公司，我们的环形路数量会比现在的多。&

Furthermore,the beam quality on far field is discussed.Temperature rise,thermal deformation,wavefront distortion and beam quality of fused quartz(SiO_2) window and white bijou(Al_2O_3) window irradiated by the annulus beam are simulated as examples.

以空心环形光束为例，计算了熔融石英(SiO2)和白宝石(Al2O3)两种常用窗口的温升分布、热变形、波前相差和光束质量，分析了冷却、辐照时间、光强分布的空间梯度和各种材料参数对光束质量的影响。

The three dials feature annular needles, symbolising an advanced level of technology.

这三个表盘功能环形针，象征一个技术先进水平。

We made huge piles of hot toast and loaded it with butter, and we made cocoa with evaporated milk that tasted like cream.

他在屋子拐角处点燃一只环形轻便煤气灶，我们烤了一大堆面包片儿，并把它们抹上黄油；我们还用尝起来像奶油的脱水牛奶做成可可茶。
