原始晶粒-
In this paper, the contrast of original image is enhanced by nonlinear transformation based on the characteristics of grain image ; after comparing several methods of threshold segmentation and analyzing their performance and applicability on grain image, the adaptive threshold segmentation based on gradient image is presented ; the noise of binary image is reduced with morphological filter, the hollow in binary image is filled in and a recognition algorithm is designed to remove agglomerate particle ; on the basis of mathematical morphology two methods are adopted to segment agglomerate grains that are not agglomerated tightly ; the parameters of size and shape, perimeter, area, diameter, complexlity, longest feret diameter, shortest feret diameter etc, are extracted. this technique is applied in measurement of pearl powder ' s particle size
本文根據粒度圖像的特點，採用非線性對比度增強處理改善顆粒顯微圖像的對比度；對多種閾值分割方法進行比較，分析了它們的性能和用於粒度圖像的適用性，在此基礎上提出了一種基於梯度圖像的動態閾值分割方法；對獲取的顆粒二值圖像進行形態濾波和空洞填充，設計了識別演算法去除凝聚體；對重疊不太嚴重的粘結顆粒採用了兩種基於數學形態學的分割演算法；提取了周長、面積、粒徑、復雜度、最長feret徑、最短feret徑等大小和形狀特徵參數，對珍珠粉等粉體粒度進行了測量。 -

獨自研發的門板工藝? ?白色烤漆門板鑼刀露出木色基材，與木紋pvc相呼映，再配合度身定做的拉手，堪稱精妙絕倫的大作。 -
Abstract : the 15 rice traces in the pottery of dulingao ruin were studied with scanning microscope. the like - indiea in grain shape and like - japonica of bi - peaked tubercle and the few remaining charac - ters of o. rufipogon of chaling area were observed, with the conclusion that they are a type of original cu - tivated minute - grain japonica
文摘:用掃描電鏡對獨嶺坳遺址紅燒土中解剖出來的15粒水稻印痕進行觀察研究，發現粒形似秈而雙峰乳突縱橫排列特徵近於粳稻，尚留有茶陵野稻的某些特徵，認定為屬於二向演化的原始小粒栽培粳稻類型。 -
We made an improvement in overcoming the defects in speech signal adaptive delta modulation ( abbr. adm ), such as slope overloading and grain noise. in this method, numerical sliding average filtering was used for filtering decoding speech signal. experiments and analyses indicate that the method makes waveforms in good agreement between the decoding of adm and the original pulse coding modulation ( abbr. pcm ) signal, and considerably improves, the playback speech quality in naturalness, legibility and under standability
針對語音信號自適應增量調制（ adm ）方式中斜率過載和顆粒噪聲缺點，提出了一種改進方法，它利用滑動平均方法對解碼后的信號進行數字濾波.試驗和分析表明，該方法使解碼后的信號波形與原脈沖編碼調制（ pcm ）波形具有很好的一致性，使再生語音質量在自然度、清晰度和可懂度方面比改進前均有較大提高 -
The process of dispersion, purification, activation and shape was introduced to make sepiolite adsorbent grain from original ore which was analyzed by x - ray radio diffraction
摘要用x射線衍射分析了原海泡石礦的純度，根據原海泡石特性提出「分散提純活化成型」的制備海泡石顆粒的工藝流程。 -
The difference is mainly resulted from the original structure and texture inhomogeneity of hot rolled steel plates, and the process of heating and annealing can also have a great effect on the inhomogeneity of the surface and center grain sizes in the steel sheets
這種區別主要來源於熱軋鋼板原有組織和織構的不均勻性，退火加熱過程也會對鋼板表面和心部晶粒尺寸的不均勻性產生很大影響。
