Programming through inhibition of the background conditions .可通過編程對背景條件進行抑制
The internal causes include the background conditions of geography and geological environment 自然地理地質環境背景條件為內因,人類工程活動為外因。
Background condition for fruit grading is simple . on the basis of stretch transform of gray level , gray image can be binarized ideally if given a overall gray segmentation threshold 水果分級的背景條件較為簡單,在灰度拉伸變換的基礎上,使用單一的全局閾值就可以進行較為理想的二值分割。
( 4 ) the intensity of the vertical movement of the air over the east of nwc , from the 1990s " , it tended to weaker , which is regarded as a dynamic background condition ( 4 )西北地區東部垂直運動的強弱具有一定的年代際變化, 90年代以來,強度趨于減弱,成為該區90年代降水減少的一個動力背景。
The results show that a warm high ridge at the middle level and transformed surface cold high over the plain provide a good background condition ; a cooling process produced by net surface radiation fluxes is the trigger and strengthening mechanism for the fog event ; the subsidence flow at the middle and low tropospheric levels is favorable for the setting - up and maintenance of stable stratification at the boundary layer and weak wind condition at the ground layer over the fog region ; the transportation of weak warm advection at lower levels and weak lift motion at the boundary layer play a very important role to the long maintenance of the fog event ; the intrusion of north wind accompanied by cold advection is a main dynamic factor of the fog dissipation 結果表明:在中高層暖性高壓脊及地面變性冷高壓穩定維持的大尺度背景條件下,地表凈輻射引起的近地層冷卻是大霧過程的觸發和加強機制;中低空下沉氣流的存在有助于近地層的弱風條件和穩定層結的建立;低層暖平流的輸入和邊界層的淺層抬升是大霧長時間持續的原因;伴隨冷空氣南下的偏北大風是驅使大霧消散的動力因子。
The essential cause inducing weather and unloading is distict difference between epigenetic - surface and deep condition . firstly , the dissertation introduces the background conditions that are the base of damsite granite rockmass weathring and unloading ; secondly , the mechanism of the rockmass weathering and unloading is probed into ; thirdly , different degree weathered zones and load - off zones are compartmentalized . tastly , right rockmass which meet the dambase demand is choosed . above - mentioned is the dissertation " s technical course which is clearly from base research to application research . 本文以黃河拉西瓦水電站壩基花崗巖體為研究對象,從風化、卸荷發生的根本原因?巖體在地表與深部存在巨大環境差異為契入點,制定了從背景條件?機理研究?風化、卸荷分帶?壩基可利用巖體選取這樣一條從基礎研究到應用研究的較為明晰的技術路線。
" debris flow disaster administration " is a kind of technology and action , by the means of law , administration , propaganda , and education , economy or others , which controls and guides people ' s reaction to disasters and behaviors relative to disasters ; which helps in negotiating every regions , departments and each steps of a activity ; which effects and improves people ' s conception of disaster deduction ; which plans and adjusts the developing goal of the course of debris flow hazard reduction and corresponding background conditions ; which designs , organizes , decides and directs debris flow in cities 所謂泥石流災害管理是這樣一種技術與行為,它通過法律的、行政的、宣傳教育的、經濟制約的或其他的有關手段,監控、約束與引導人們對于災害的反應與有關災害的行為;協調有關災害的各個區域、部門與環節;影響和改善人們的減災觀念;規劃與調整泥石流減災事業的發展目標與相應的背景條件;設計、組織、決策與指揮和城鎮泥石流及有關的重要活動,或通過其他的方法達到有利于系統提高減災效益目的。
Part iii anatomizes the causes of the crime of inquisition by torture and confession - extortion from six aspects and points out that the permeation of traditional law culture and the load of social control function are its background condition , that the warp of executing - the - law concept in the prosecutors is the individual factor for its occurrence , that the absence of the rule design for the litigation procedure and the careless omission of the law rules and regulations are the institutional causes of its occurrence , and that the lack of judicial resources is an objective factor for its occurrence 第三部分:文章從六個方面剖析了刑訊逼供犯罪的成因,指出傳統司法文化的浸染、社會控制功能的負載乃其背景性根源;司法人員執法理念的偏差是刑訊產生的個體因素;訴訟程序規則設計的缺失、法網規制的疏漏是刑訊逼供發生的制度性原因;司法資源投入的短缺是促使刑訊發生的一個客觀因素。
Regional photochemical reaction is weak over this area , to a great extent , the atmospheric background condition influences to the variation of surface o3 , tthe variation of vertical wind speed is significant to surface o3 , from seasonal distribution of vertical wind , it appears upward air current in winter , spring and autumn , repectively , while it is mainly downward in summer , it is favorable to the o3 transport from stratosphere layer . at walilguan , the variation of humidity impacts a little on surface o3 , the relationship between surface o3 and wind speed is relatively complicated , by correlation statistic analyze , it is sure that the wind speed is not one of the important factor ( 2 )瓦里關地區局地光化學反應較弱,地面o _ 3在很大程度上受大氣背景狀況的影響; ( 3 )垂直風變化對地面o3日變化影響較大,從垂直風季節分布看,春、秋、冬三個季節為上升氣流,而夏季下沉氣流則很旺盛,這種分布有利于平流層o _ 3向下的輸送; ( 5 )濕度對地面o _ 3貢獻并不明顯; ( 6 )各季節水平風速與地面o _ 3之間的關系較為復雜,不同季節相關分析表明,水平風速并不是影響地面o _ 3變化的主要因子之一。
