中文拼音 [chuángcéngmìdù]
床層密度
英文
bed density-
With the tracing particles, the sinking velocity of middle and higher density particles that pass through the lower density coal particles in jig bed for different jigging air circle were measured. the results showed that the air cycle with a long inlet period can promote the separation of middle and higher density particles and lower density coal particles
運用彩色人工顆粒，對不同跳汰周期下中、高密度顆粒在低密度煤炭床層中的沉降速度進行了示蹤研究，確認長進氣期周期有利於中、高密度顆粒與低密度煤炭顆粒的分離。Such grids effectively smooth out the velocity fluctuation above the dense bed.
柵格在密相床層上有效地使速度波動平緩起來。Jejunal biopsy through enteroscopic examination revealed atrophic villi and dense infiltration in lamina propria by lymphocytes, with extension beyond the layer of muscularis mucosa
我們報告一例具典型臨床癥狀的31歲男性患者，其空腸切片檢查看到黏膜固有層中有緻密的淋巴漿細胞浸潤，浸潤程度已穿越黏膜肌肉層。The control of the deep - seated structural - magmatic process over the metallogenic system around the middle - lower yangtze river reaches is shown as : ( 1 ) the mantle uplift belt is closely related to the general geological background of the metallogenic system ; ( 2 ) the primitive magma originated from different parts of the mantle uplift belt ( mantle ridge or mantle slope ) shows differences in style of formation and composition and results in different magmatic series and metallogenic subzones, respectively ; ( 3 ) the varying depths of structural - magmatic chambers may form a " three - layered structure " ( central type, network - like and ring - like ) and this is the primary factor that controls the different magmatic series and the concerned cluster of ore deposits ; ( 4 ) the alkaline basaltic magma derived from the mantle ridge forms high - potassium and calcium alkaline magma and shoshonitic magma due to its altering intensity of afc process with the lower crustal material, which has something to do with the copper - gold and iron - sulphur metallogenic subsystems, respectively
深部構造巖漿作用對長江中下游成礦帶安徽沿江地區成礦系統的控製表現為： （ 1 ）地幔隆起帶與成礦系統的總體地質背景的演變密切相關； （ 2 ）源於地幔隆起帶不同部位（幔脊與幔坡）的原始巖漿，其生成方式和物質組成不盡相同，它們分別產生相應的不同巖漿巖系列和成礦亞帶； （ 3 ）不同深度的構造巖漿房組成中心式網格式環帶式「三層結構」 ，是控制區內不同巖漿巖系列及有關礦床集中分佈的主要因素； （ 4 ）源於地幔隆起帶脊部的堿性玄武巖漿，由於與下地殼物質發生的afc作用強度不同，形成了高鉀鈣堿性巖漿和橄欖安粗巖漿，分別與銅、金成礦亞系統和鐵、硫成礦亞系統有關。Numerical simulation of solid flows and density distribution in air dense medium fluidized bed
