盲区

An example of an antenna blind cone is that of an air route surveillance radar.

天线盲区的一个例子是航路监视雷达。

A three-axis electro-optical tracking system can be used to track any space target in all azimuth. It can rapidly and accurately track the target in the altazimuth zenith blind region by rotating X axis.

三轴光电跟踪系统可以全方位跟踪空间目标，在地平式光电跟踪系统天顶盲区内通过转动X轴实现快速高精度跟踪。

We analyzed and proved that this kind of mounting can cover all useful sky area and has much lower and smoother angular velocity and acceleration than the altazimuth one. IN THIS PAPER WE ALSO DISCUSSED THE RELATIONSHIP BETWEEN TWO MOST OFTEN USED ALT-ALT coordinate systems (SN-ALT-ALT, EW-ALT-ALT coordinate system) and the sidereal hour-angle coordinate system, the horizon coordinate system.

本文推导了ALT-ALT跟踪机架光电人卫跟踪仪原理，分析证明了它在要求的跟踪区域内不存在观测盲区，对同一目标的跟踪角速度和角加速度比地平式机架跟踪仪小且平滑，可实现全天覆盖。

In this sense the astrometry and radial velocity planet-hunting methods complement each other, each excelling in the other method's blind spot.

从这一意义上说天体测量和视向速度行星搜索法是互为补充的，各自在彼此方法的盲区表现出色。

One usually democratic principal says,"My responsibility as a principal really is to the children and if I see areas that are ineffective, I've got to say that we're not effective here and that we have got to change"(Blasé and colleagues).

一位较民主的校长说："我作为一名校长的责任在于对小孩子负责，如果我看到了没效用的盲区，我会承认此处的作用仍没效，因此，此处需要改变。"

That suggests the helicopter may have been flying in a blind spot for Steve Altman, the pilot of the Piper Lance and one of the brothers aboard.

这显示出直升机当时可能正在私人飞机驾驶员、两兄弟之一的艾特曼的盲区中飞行。

From this case, we look in order to see, the website optimizes a concept popularize limits far insufficient still, certain even industry returns Ren Ran is blind area, resemble young pig industry same.

从这个案例上，我们看以看出，网站优化理念的普及范围还远远不够，甚至某些行业还任然是盲区，就像仔猪行业一样。

The car hit me on my blind side.

那辆车撞到我的车的盲区。

Like the eyesight of these two men, their relationship suffers from ambivalencen other words blind on one side and seeing on the other.

两人的关系如同两人的视觉一样存在盲区，两人都不曾真正看透对方。

The results of the simulation analysis and experiments indicate that the loss of ultraviolet scattering transmission in atmosphere is high because of the particle scattering and absorbing in solar-blind zone; that is, the received power can descend 20 dB with the distance increasing 10 times. Therefore, the ultraviolet scattering is fit for short range communication. In short range, the pulse extension due to scattering is at microsecond order and its influence for low and moderate bit rate communication systems is weak. Since the light output power of a single ultraviolet LED is low, a multi-LED array can be used to increase the transmit power and extend the communication range.

仿真分析与实验结果显示：日盲区紫外光在大气中散射传输时由于大气粒子的强烈散射与吸收，传输损耗较大，距离每增加10倍，接收功率下降20dB，因此日盲区紫外光大气散射通信适用于近距离通信场合；近距离传输时散射造成的光脉冲多径展宽为微秒量级，对中低速通信系统影响较小；单个紫外LED发光功率较低，可通过多个LED阵列来提高发射功率，增大通信距离。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
