查询词典 off the beam

The measuring device is structured by including a He-Ne laser; a beam expander, a soft aperture slot and a off-axis parabolic mirror to be measured are arranged in turn along the direction of the emergent laser beam direction of the He-Ne laser; a standard cross hair and a micro objective are arranged in turn on the direction of the reflected beam of the off-axis parabolic mirror; the micro objective is arranged on the focus of the off-axis parabolic mirror; the focus is imaged on an area array CCD; the output end of the area array CCD is connected with a computer; the off-axis parabolic mirror is fixed on a five-dimensional electric adjusting frame.

一种离轴抛物面镜点聚焦能力测定装置和测定方法，测定装置的构成包括：一台He-Ne激光器，沿该He-Ne激光出射激光束方向依次设置扩束器、软边光阑和待测的离轴抛物面镜，在该离轴抛物面镜的反射光束方向依次设置标准叉丝和显微物镜，该显微物镜位于所述的离轴抛物面镜的焦点，所述的焦点成像于面阵CCD上，该面阵CCD的输出端接计算机，所述的离轴抛物面镜固定在一五维电动调整架上。

So that while the beam is off, energy is building up for the next flash, and when it comes, it is very intense flash, with a lot of power packed into it.

所以在光束灭的期间，就为下一次闪光聚积起能量。而一旦它再亮时，由于已聚积起大量的能量，闪光就十分强烈。

To achieve beam positioning off the boresight axis, it is necessary to radiated the antenna elements out of phase with one another.

要使波束位置偏离视轴线，就必须要使单元发射相位互相不一致。

I fell off a beam in the barn loft yesterday, while I was trying to crawl over to a nest that the black hen has stolen.

昨天在粮仓，我想爬过去构一个鸟巢，不小心从梁上摔了下来。

Sure enough, as she came down to land the somersault that opens her routine, her right foot slipped off the edge of the 4-inch beam.

果然，当她翻上平衡木开始比赛时，右脚滑落了仅4英寸的平衡木。

Finite Difference Time Domain method is adopted to evaluate the relationship between the off-axis angle of the beam and the temperature difference.

由时域有限差分方法得到光束偏转角度与温度差之间的关系。

Because of having big gap between rail s and situating floating status of I-beam girder of rail foundation at production area of coke oven the unstability operation or off the rail could be easy happening.

分析认为拦焦车轨道运行状况较差的原因是拦焦车轨道轨距较大，炉区轨道基础工字钢梁处于浮动状态，极易因轨距进一步扩大而威胁车体平稳运行甚至造成拦焦车脱轨。

Stand on the beam on the ball of one foot, lifting the other leg and using it and your arms to find a balance point. When you've mastered that, try standing on one leg with the other leg behind you, and then lean forward with your upper body while raising your back leg as high as possible, using only your outstretched arms as stabilizers to stave off a face plant.

用一只脚的圆形部位站在杆上，举起另一只脚然后用手臂来保持平衡，当你已经可以自由运用，尝试站著时，另一只脚伸到后面抬得愈高愈好，同时身体往前倾，只用你伸出去的那支手当平衡器免得脸摔到地上。

In any type of let - off motion in which the warp sheet passes over a back roller, the tension in the horizontal part of the warp sheet will be greater than that in the warp sheet between the back roller and the beam

任何类型的送经机构，经纱片均绕过后梁，处于水平位置的经纱的张力要比后梁与织轴之间的经纱张力大。

In any type of let-off motion in which the warp sheet passes over a back roller, the tension in the horizontal part of the warp sheet will be greater than that in the warp sheet between the back roller and the beam, because if the back roller rotates, force is required to overcome friction in its bearings, and if the back roller does not rotate, there will be friction at its surface.

任何类型的送经机构，经纱片均绕过后梁，处于水平位置的经纱的张力要比后梁与织轴之间的经纱张力大。这是因为，如果后梁转动，就需要力来克服轴承处的摩擦；如果后梁不转动，在后梁表面会有摩擦。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
