There are two parts in this paper : firstly, a set of single doppler velocity models are presented for typical ambient windfields that include those of being uniform horizontally, macroscale convergence and divergence, which overlap warm and cold advection. which are marked by different signatures in the single doppler velocity field. the models proposed can help users identify useful information from the dopple velocity patterns
本論文包括兩個部分：第一篇通過對典型風場的單多普勒天氣雷達徑向速度圖象進行模擬，典型風場包括水平均勻一致的風場、非均勻水平風場的大尺度運動的輻合輻散風場以及大尺度運動的輻合輻散風場與冷暖平流的迭加等。 -
Experimental constants include : ambient temperature 291k ~ 301k, rh 15 % ~ 21. 2 %, wind velocity 3. 2m / s at the nozzle position and horizontal to the spray fan, others are same as the fore experiment. the tendency of the two experiments results is consistent with the tendency from simulation. that indicate the improved shield spray is better than the original shield spray in reducing spray drift, and also more better than conventional spray without shield
風洞試驗參數：噴霧藥液為含1 bsf的水溶液，風速1 . 4m s ，風向垂直於噴霧扇面，溫度281k 288k ，相對濕度rh9 20 ；室內試驗參數：噴霧藥液為含2 bsf的水溶液，噴頭處風速為3 . 2m s ，風向平行於噴霧扇面，溫度291k 301k ，相對濕度rh15 21 . 2 ；分別在噴頭下風向噴幅外的空中和地面布點收集飄失和飄移沉積的霧滴量，作為評價減少霧滴飄失效果的指標：試驗結果表明：改進后的罩蓋噴霧減少霧滴飄失的效果好於雙圓弧未開口罩蓋噴霧，常規無罩蓋噴霧的霧滴飄失量大於開口罩蓋噴霧。 -
The captured droplets weight is regarded as evaluating indicator. experimental constants include : ambient temperature 281 - 288k, rh 9 % ~ 20 %, wind velocity 1. 4m / s and vertical to the spray fan
風洞和室內試驗比較了結構改進前後的罩蓋噴霧減少霧滴飄失的效果，並和常規無罩蓋噴霧對比。 -
The coherence analysis of the sound field using prssure and particle velocity combined processing was discussed. a new kind of combined sensor was used to gather the information of the sound field. the main idea of this paper is to seperate ambient noise field ， and the characteristics of it can be further studied. the coherence of a point source sound field was also analyzed to verify the validity of the approach
聲場聲壓與振速的相干性是聲壓、振速信息聯合處理的重要物理基礎之一，本文對其進行了初步的分析.在新型組合傳感器湖試的基礎上，把環境噪聲場分解為不相干的各向同性分量和相干的各向異性分量，初步分析環境噪聲場的構成；同時對點源聲場的相干性也進行了驗證性的分析
