中文拼音 [yùwùzhí]
閾物質
英文
threshold bodies bodies-
The relative momentum of two final particles and the cross section are zero at the threshold energy for an endothermic reaction, while the relative momentum of two initial particles is zero and the cross section at the threshold energy for an exothermic reaction is infinite
在吸熱反應的閾能處,出射粒子的相對動量以及截面均為零。在放熱反應的閾能處,入射粒子的相對動量為零,截面趨于無窮大。由於強子的動量僅提供如此低的質心系能量,強子物質中x 。In the uv light region, the absorption dramatically increases that is caused by the absorption of the films substance, hi addition, as the heat treatment temperature increases the absorption threshold slightly occurs " red shift "
在紫外區,薄膜的吸光度急劇增大,而且,隨著熱處理溫度的增加,吸收閾值發生輕微的「紅移」 。這種降低是由於薄膜物質的吸收所致。This paper stuffed with twelve important grain and vegetable crops, studied the injury symptom, dose reaction, injury threshold value and influential factor of main pollutant so2 on various plants, tested the dynamic transformation of pod, cat, mda, soluble protein, free pro and chlorophyll of resistant plant and sensitive of these physiological biochemical transformation with plant resistant ability. meanwhile, simply studied the protective role of the five compounds on plant. the result indicated the followings
本實驗以12種重要的糧食和蔬菜作物為研究對象,研究了主要大氣污染物二氧化硫( so _ 2 )對不同植物的傷害癥狀、劑量反應、傷害閾值以及影響因素,測定了抗性和敏感植物在受到so _ 2污染后植物體內過氧化物酶( pod ) 、過氧化氫酶( cat ) 、丙二醛( mda ) 、可溶性蛋白質、游離脯氨酸和葉綠素的動態變化,並分析了這些生理生化變化和植物抗性的相互關系,同時還對5種化合物溶液對植物的保護作用進行了初步研究,結果表明: 1Those substances presented the characteristics such as low threshold value, sensitive under low temperature, and low variance, which caused the complexity of luzhou - flavor liquor flavor and the great difference by tongue tasting
苦味物質表現出閾值較低、在低溫下較敏感、可變性小、可使濃香型酒風味復雜、舌各部位對苦味的敏感程度差異較大等特徵。The algorithm builds voxel between neighboring slices of volume data, then gets density of a certain substance by experience. after setting threshold for surface of the substance which we want to get, and computing triangle mould of every voxel cube by use of linearity interpolation, the algorithm represents the surface of the substance as the form of triangle mesh
該演算法通過在相鄰的體數據切片之間構建體素,根據經驗獲得某一種物質的密度值,設定待求物質表面的閾值,利用線性插值求出每一個立方體體素的三角剖分的構型,進而將整個物體表面以三角型網格的形式表示出來。This article introduces the process and requirements of detection set by iaea in the light of the need for detection, setting of investigation levels and alarm threshold, selection of instrument, location and evaluation of radioactive materials
本文從探查需求分析、調查水平和報警閾的確定、儀器選擇、探測報警、核查定位、鑒別等幾個方面介紹了對非法運輸放射性物質進行探查的一般過程和要求。A new image sampling method and a device for transmission flow measuring are provided, and an edge detection method based on the semantic weight and threshold selection tactics based on the vision model are used to extract the contour, calculate the area and volume within a short time span
設計了一種新型的用於傳輸流量檢測的圖像採集方法和裝置,並利用基於語義權值的邊緣提取方法和基於視覺模型的閾值選擇策略進行傳輸帶上物質的截面輪廓線提取,計算物質截面面積和較短時間內的流量體積。分享友人
