查询词典 precision barometer

Main job is to guarantee the scraping interaction and equipment on both sides of the friction surface or can obtain higher precision and accuracy, precision and shape accuracy, precision and contact transmission because of good lubrication, manual and repeatedly is worthy, large amounts of wind, time-consuming, scraping the time needed for different devices vary, such as boring slider and slide block wind profiling, between the match before measuring clearance between the original value, and then according to the technical requirement to measure the value of time and scraping scraping, then apply DanFen red on the slider, manual let slip on the slide seat back and forth, they do straight-line movement between full contact and friction, reoccupy scraper scraping friction creates the contact point, so repeatedly, until the technical requirements for the match, single within 2 days, must blow to the boring if all the time to work with wind, a half month is required.

刮削过程。刮削工作主要是为了保证设备相互接触并摩擦的两面间能获得较高的尺寸精度、形状精度、位置精度、接触精度、传动精度和良好的润滑，因是手工操作且需反复配刮，故工作量大，耗时较长，设备不同，刮削所需时间也各不相同，例如镗床上滑座与下滑座间的配刮，刮削前先测量出二者之间原有的间隙值，然后根据工艺要求测算出需刮削值及每次的刮削量，再将红丹粉涂于上滑座之上，手工让上滑座在下滑座上来回做直线运动，使它们之间充分接触和摩擦，再用刮刀刮削摩擦产生出的接触点，如此反复多次，直至技术要求范围之内，单此项配刮需2天左右，若对于整个镗床所有配刮工作的时间总和，则需半个月左右。

High-precision spherical components have been widely used in precision machinery and aerospace industry, and spherical curvature is one of determinant to the capability of optical components, and the measure of it is an important matter in the optical component manufacture. So the research of the high precision measurement of spherical curvature has important significance.

中文摘要高精度球面元件在精密机械和航天工业中的应用越来越广泛，在光学生产的加工制造过程中也大量需要对具有球面形状的透镜的曲率半径进行高精密测量的情况，因此，球面元件曲率半径的精密测量对高质量球面样板，光学系统的质量控制等方面具有重要的意义。

And this causes a frequency change Δf. The resonant point tracing algorithm describes how to detect Δf. So it can introduce a feedback frequencydifference -Δf through a closed loop to realize the resonant state o In the digitaldetection scenario, using staircase wave to replace saw tooth wave, it can overcome a lot of shortcomings in the analog system. The character of the staircase wave affects the detection precision directly. This thesis analyzes a high precision scenario producing a staircase waveform in detail. It can reduce the number of the bits in D/A converter greatly. This thesis proposes another method to improve the detection precision in case that the A/D converter has comparatively little number of bits, while this method will not increase the cost of the system greatly.

在谐振式光纤陀螺中，环形谐振腔的旋转使得谐振腔的谐振频率发生了变化，从而产生了一个与旋转速度成正比的频率变化值△f，谐振点跟踪算法描述了如何检测出△f，从而可以通过闭环在系统中引入反馈频差-△f，实现光路的谐振状态；在数字闭环检测方案中，用阶梯波作为反馈信号来代替锯齿波，可以克服原来模拟系统中锯齿波的很多缺点，阶梯波的性能直接影响着系统的测量精度，本论文详细分析了一种高精度阶梯波生成方案，使得所需D／A的位数大大降低；本文还分析了A／D转换器对系统测量精度的影响，提出了一种A／D转换器位数较少的情况下提高系统测量精度的措施，同时又不会增加太多的系统成本。

However, current WSN applications in Precision Agriculture all adopt the traditional client/sever model, data are sent from the source to the destination, because of hugeous data, high concurrency and strong signal interference in Precision Agriculture and the extremely limited sensor network resources, such client/sever model hampers WSN applications in Precision Agriculture.
