盲区

Unfortunately,the surge protection devices are occasionally faulty because of the protection indeterminateness due to the design and installation of SPD.We discussed the random characteristic of lightning strike,the breakdown time delay and jitter of SPD,multi-stages protection blind zone,the reflection oscillation of lightning wave between loads and SPD's,and proved the indeterminateness o...

由于SPD设计和施工带有多方面的不确定性，使被保护系统可能出现故障，导致SPD保护失效，因此从雷击特性的随机性、组成SPD元器件的击穿时延和分散性、多级保护盲区、雷电波在负载与SPD之间的反射振荡特性等方面进行了分析探讨，最终得出了SPD保护不确定性的必然性。

Currently there are two kinds of radio navigation resources in our country. One is the Changhe Ⅱ loran, which mainly overlays inshore regions of our country and serves for ships. The advantages of this system include the strong transmitting power, the wide overlaying region, and simple receiving technique.

我国目前现有的无线电导航资源有两种：一个是"长河二号"无线电远程导航系统，主要覆盖我国近海区域，主要为舰船提供导航，该系统发射功率大，覆盖广，接收技术简单，其缺点是导航精度低，在两个台链的结合部会出现盲区。

In the described system, in order to transmit the narrow-band analog signals or low speed digital signals at any time and under any climatic condition, sun-blind-region ultraviolet is used as information carrier, the modulated low voltage mercury-vapor lamp is used as emission device.

所描述的系统是以日盲区紫外光作为信息载体的，用被调制的低压汞蒸汽紫外放电灯作为发射器件，以日盲型滤光片和光电倍增管或日盲型紫外光电倍增管作为接收器件，以达到在任何时间和在任何气候下完成窄频带模拟或低速数字信号的传输。

In this system, the combined orientation model of DTWADGPS is established using the WADGPS, odograph, speedometer and roscope, etc. And the information of the multi-sensor is processed using the method of data fusion, which is used to resolve the accuracy and blind area problems of train position Combining the technology of GIS and GSM-R and the Expert System, the system of intellectualized train dispatch and management is established based on train positions and velocities acquired accurately.

系统采用WADGPS、里程表、车速仪、陀螺仪等构建分布式逆向WADGPS组合定位模型并对多传感器信息进行融合处理，解决列车定位的精度和盲区问题；在精确获取列车位置和速度的基础上，结合GIS和GSM-R技术和专家系统构建列车智能调度管理系统。

By comparing the open-loop control system, closed-loop control system and mixed-loop control system, the paper drew a conclusion that the new control system could shorten the blind area, eliminate the dead area, and autolevel cotton sliver twice.

通过比较开环、闭环和混合环控制系统认为，该控制系统能够缩短盲区，消除死区，并能2次匀整条干。

If you overdrive your headlights, you create a blind crash area in front of your vehicle.

假如你超过这个范围，车前面就会形成一个可能导致撞车的盲区。

The perpendicular and longitudinal distance of the radial branch to the radial styloid was （0.8 ± 0.3） cm and （1.5 ± 0.4） cm respectively.

结论以桡骨茎突为中心，横向距离0.4cm，纵向距离0.6cm的椭圆形区域为桡神经分布相对盲区，从该区经皮克氏针固定桡骨远端，可有效地减少桡神经浅支损伤的发生率。

For this purpose, this paper first analyzes the improved algorithm of complex polyphase filters and its mathematical module, which meet the requirement of receiving signals without leaking.

针对这一问题，首先分析了复信号多相滤波器无盲区算法及其数学模型，实现信号的全概率捕获。

This information is in my blind quadrant because you can see it, but I cannot.

这种信息就在我的盲区象限中，因为你可以看到，而我却不能。

The "blind" quadrant represents things that you know about me, but that I am unaware of.

"盲区"象限代表那些你所知道的关于我的事情，而我却毫不知情。
