点采样 meaning in Chinese
point sample
Examples
- The border panoramas are created by constraining viewpoint motion to arbitrary convex region of a plane , and sampling cylindrical panoramas at border of the region point by point
边界全景图通过限定视点在平面上任意的凸区域内运动，并且在区域的边界上逐点采样柱面全景图而构成。 - After we adjust the models of terrain and plants with other important parameters , we use some techniques such as sample points , multi - resolution to generate the whole meadow scene with high sense of reality
将造型好的地形、植物和其他参数整合之后，采用多种先进的绘制手段如点采样技术、多分辨率技术等，绘制出具有高度真实感的草地场景。 - It is different from concentric mosaics as follows . the sampling region of border panoramas can be arbitrary convex region , such as rectangle , square , triangle , circle or any other shape . and its sampling manner is sampling cylindrical panorama at border of the region point by point
它与同心拼图( concentricmosaics )的不同之处在于，采样区域可以是任意的凸区域，比如矩形、三角形、圆或者其它随意的形状，采样方式是在区域的边界上逐点采样柱面全景图。 - Parallel structure of poly - phase decomposition and parallel mixer is applied in the ddc circuit , it solves the bottleneck in mixing and increases the handle speed . the partition of the tuning channel according to the digital mixing sequence , and the ddc by means of decimating first , the low - pass filtering and mixing realize efficiently the down - conversion of the variable carrier frequency band - pass signal . according to the structure of the ddc and the requirement of the frequency
短数据快速测频算法的具体实现:使用并行流水线的设计方法,提高了系统的数据吞吐率,在100mhz的系统时钟下,能够实时处理400mhz ~ 600mhz速率a / d采样的数据,在64点采样, 100mhz系统时钟情况下,初次测频占用时间640ns ,以后每次测频占用时间缩短到160ns ,实时地提供多相滤波下变频所需的载频位置信息,缩短了接收机的调谐时间。 - As the agricultural nfs is the most important factor for water environmental deterioration and lake eutrophication in china , more and more scientists and technologists focus on the control countermeasurc and pollution mechanism of agricultural non - point source ( nfs ) . based on the investigation of natural resource and agricultural distribution , the loss rule of nitrogen and phosphorus in the typical land of qiandao lake watershed and distribution rule of the phytoplankton and physico - chemical characteristic in the lake were studied , and the input loading of nitrogen and phosphorus was also calculated by the annagnps model in this thesis . according to the routine monitoring data of the water environment in qiandao lake from 1989 to 2001 , the concentrations of toxic substance and heavy metal were under the monitoring limit , but the total nitrogen ( tn ) and total phosphorus ( tp ) were much higher than the criterion for lake and reservoir
本文调查了千岛湖流域的自然资源和农业生产情况，研究了典型坡地降雨径流中的氮、磷污染物的输出规律，利用annagnps模型估算流域农业非点源污染物输入负荷，并在千岛湖内设点采样，对水质理化指标和浮游植物群落进行系统的研究，得出以下结论： 1989 2001年间的水环境常规监测资料统计分析表明，有毒物质和重金属浓度长期在监测下限内， no _ 2 - n 、 no _ 3 - n 、 nh _ 3 - n年平均浓度均符合类标准，但湖泊水库特定项目tn和tp浓度分别为超类和类，呈严重超标状况，湖区主要污染因子是将导致富营养化的物质tn和tp 。
