By comparing the dry plate pressures drop and distributions of velocities simulated on single valve with those of double valves, it was found that there was intense turbulence in the flow fields around fixed - valve, there were eddy areas between valve side orifices and tray wall, there were eddies above the valves too, these led to the complex behaviors of gas perforating valve, these had a great effect on the gas - liquid mass transfer process. at the same time, in order to prevent the disadvantageous effect of gas between one valve with another on the gas - liquid mass transfer, it was very effective to change the fields of gas perforating valve by folding the edges of valve
通過對數值模擬得出的單閥和雙閥塔板的干板壓降及流場速度分佈分析對比后發現，固定閥周圍流場存在較強的湍動，閥側孔與塔板壁面區域以及閥體的上方空間存在明顯的渦流區，使氣體穿閥后的行為變得復雜，並對氣液傳質過程產生重大影響；模擬結果表明，為防止和削弱固定閥間的對沖造成的「死區」對傳質帶來的不利影響，通過折邊來改變氣體的氣路是非常有效的，模擬值與實驗值基本得到吻合。Botflies ( such as the one featured in these photos, the human botfly, or dermatobia hominis, commonly found from central mexico through to central america and south america ) are one of a number of insect species that lay their eggs on the exterior of other living creatures ( usually mosquitoes or flies ) ; when the eggs hatch, the larvae burrow into their " hosts " to feed ( breathing through the small burrow holes ) until they emerge to pupate into mature adult botflies

整體縮微膠片承載器縮微膠片檢索穿孔卡照像機拷貝和圖像卡的安裝區域的厚度的測量方法That is, the partially penetrating sand drain ground is viewed as the double - layered ground, and its consolidation is analyzed with 1 - d consolidation theory, through the transformation from 3 - d consolidation to 1 - d consolidation in the region of sand drain. this can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under - lying soft layer. to the double - layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory
然後，在充分考慮豎井區井阻、塗抹作用以及土體結構損傷破壞對固結影響的基礎上，將未打穿豎井地基合理地轉化為雙層地基，按一維固結理論計算，克服了傳統固結計算方法在豎井處理區與下臥層交界面處存在孔壓間斷的缺點；在此基礎上，從超載預壓法的基本原理出發，分析了雙層地基超載預壓固結、沉降機理，推導了多級等速加、卸載情況下雙層地基的固結計算公式，進一步完善了雙層地基固結理論。For patients with these underlying cardiac conditions, prophylaxis is recommended for all dental procedures that involve manipulation of gingival tissue or the periapical region of teeth or perforation of the oral mucosa
