In the process of devising rainfall apparatus, the calculative formula of traditional rainfall degree of consistency ca n ' t weight the uniformity of rainfall space. the paper suggests the checkup parameter and calculative method used in testing the degree of consistency of the rainfall intensity in rainfall space
在降雨器設計中，傳統的降雨均勻度計算公式並不能衡量降雨強度空間分佈的均勻性，本文提出了檢驗雨強空間分佈均勻程度的校驗參數及檢驗空間均勻度優劣的計算方法，給出了校驗該參數應達到的最小值。 -

Eddy current nondestructive testing ( ecndt ) is widely used to detect the thinness and defects of the sample, because of its characteristics of non - contact, high sensitivity and ease of detection. the principle of ecndt is that : when a probe coil with the ac exciting source is put near a sample, eddy current will be produced in the sample which will conversely affect the impedance of the coil according to the farad theorem. any un - uniformity in the sample will change the impedance of the coil and the output voltage
渦流無損檢測技術具有靈敏度高、檢測速度快、非接觸等特點廣泛應用於厚度檢測和缺陷探傷，它的原理是當載有交變電流的檢測線圈靠近金屬導體時在導體中產生渦流，該渦流又影響原磁場，使得線圈的阻抗和感應電壓發生變化，通過分析阻抗或感應電壓的變化來獲得被測導體的信息。 -
At present, the problem in testing sheet resistance for micro - areas is that probes must be set up at the suitable locations by handwork. in order to know the wafer ' s impurity distributing, we need test many times, so will waste a lot of time. if the wafer ' s diameter would be 300mm, this problem will be more serious. in this paper, image analysis is introduced, through pre - processing and edge picking - up, the probe tips are recognized. then probe tips will be aligned respectively in two perpendicular directions through driving stepper motors. thus the distribution of sheet resistance for whole wafer is got by automatic testing and it offers information for detecting the impurity distribution and the diffusion uniformity
這樣，完成200mm （ 8時）圓片雜質的擴散分佈需要對許多圖形進行測試，需要花費很長的時間，當測試300mm矽片時問題就更為突出。本文將圖象與視覺測量系統引入四探針測試系統中，對採集到的原始探針圖像進行預處理、邊緣提取等操作，以便實現探針針尖的識別，然後由電機控制實現探針的自動定位。這樣測試系統可以自動獲得全片的薄層電阻分佈，為超大規模集成電路檢測雜質分佈和擴散的均勻性提供信息。
