area of field meaning in Chinese
油田面积
Examples
- Computing method and programming of area of field block based on gps
的田块面积计算方法及程序设计 - Thanks to the excellent field - emission property , cnt and its composites have tremendous application potential in the area of field - emission vacuum devices , especially panel display
因为碳纳米管及其复合材料具有优异的场发射特性,因此在真空场发射器件尤其是平板显示器方面具有巨大的应用前景。 - Although many researchers have been working hard during the past few decades in the area of field strength prediction , there are still numerous problems to be solved . to date , a perfect propagation model has not been found
尽管经过几十年的研究和发展，提出了不少预测模型，但大多是在某一环境下适用，至今仍然没有一个精确可靠的微小区电波传播预测模型。 - In fast axis the divergentce of each beam is 0 . 28o , in slow axis is 1 . 4o , the area of field from the end of ld stack 20cm is 42 25mm2 , average wave is 9 . 3 % . so , it can meet the requirement of pumping , and the effect is fairly good
具体数据为:各输出光束在快轴方向的发散角为0 . 28o ,在慢轴方向的发散角为1 . 4o ,输出光场在距ld面阵发射端面20cm处的面积为42 25mm2 ,平均波纹起伏为9 . 3 % ,可见整形效果较好 - The first part mainly introduces the gis concept and contents of gis , the comparison between the related software and gis , the present condition and development trend of gis etc , then introduced how to use the gis technique in a specific way such as using the method of " the half - automatic to follow " to turn the map into arithmetic figure , using the method of " the automatic calculates " gets the length of the line and area of field etc , at last got the length and width of every cross section of the fabiela river which is located downstream of xiangshan mountain . this method is superior and time - saving comparing with collecting data on the spot , having important and actual application worth
第一部分主要介绍了gis的概念和研究内容， gis与相关软件的比较以及gis的现状、发展趋势、当前gis研究的热点等等，然后具体介绍了用gis的相关技术如：用“半自动跟踪”方法对地图进行数字化，用“自动量算”方法得到线对象的长度、面对象的面积等，最终完成了象山水库下游法别拉河河道地形数据资料的提取工作，这种方法与人工实地采集工作相比，有较强的优越性和重要的实际应用价值。
