Firstly, simulate flow field of rear smoke channel, plot velocity magnitude and ash concentration distribution in section of entry of heat pipe air preheater, compare with data which were measured in guiyang power station, verify simulation to be reasonable and right. secondly, simulate all kinds of factors which affect flow field ' s uniformity such as length, thickness, location of diffluent board, ash concentration, ash diameter, and so on, find the chiefly factors. thirdly, install guide board in curve channel in rear smoke channel, then simulate its " flow field, plot velocity magnitude and ash concentration distribution
在此基礎上模擬在冬夏兩季不同情況下，不同流速對熱管空氣預熱器壁面溫度的影響；然後對影響整個流場分佈的各種因素：包括分流板長度、厚度、偏離中心流道位置的偏離度、飛灰濃度、飛灰粒徑等因素進行數值模擬；最後提出在分流煙道轉彎處加裝導流板，並模擬加裝導流板后的流場分佈，得到下級空氣預熱器出口、熱管空氣預熱器進口處的斷面速度場分佈、濃度場分佈，以論證加裝導流板能達到流場均勻化的作用。Effects of different calcium concentration on ca2 + in ca2 * - sequester ing organelles of photoreceptor cell in penaeus monodon fabriciu by the combined oxalate - pyroantimonate technique, we observed the subcellular distribution of calcium in the photoreceptor cells of penaeus monodon fabricius, by changing the extracellular calcium concentration. the result showed that, in vitro, in presence of 50mmol / l, the quantity of calcium antimonate deposit in the multivesicular bodies, pigment and lamellar body were more than that of photoreceptor incubated in lower calcium solution, which contained 50mmol / l egta. in higher calcium solution, we ecu id not f i nd the depos i t in the mitochondr ia, but in lower calcium solution, there was a little deposit in the mitochondria
學位論義小同ca卜濃度對斑節對蝦光感受器的形響3 .外界不同鈣離子濃度對斑節對蝦光感受器細胞內所儲存的鈣離子的影響應用草酸一焦銻酸鹽結合的沉澱技術研究斑節對蝦光感受器細胞在不同ca之『濃度條件下胞內儲存的ca2 +變化，其電鏡觀察表明:在高鈣溶液培育后，細胞內的多囊體、色素顆粒、板膜體中都存在大量的焦銻酸鈣沉澱的黑色顆粒，線粒體中未發現沉澱;在生理溶液培育后，線粒體中出現沉澱，而其他caz +儲存器中焦銻酸鈣沉澱的黑色顆粒大量減少。The comparison of stomatal parameters in leaf cuticles between two fossil angiosperms from the pliocene in west yunnan and their nearest living equivalent species indicates a little higher atmospheric co2 level at that time than the present, while carbon isotopic composition of fossil cuticles demonstrates much higher carbon isotopic discrimination and slight lower water use efficiency, showing a warmer and wetter climate than today
摘要對滇西騰沖新近紀兩種被子植物葉片及其現存對應種的氣孔參數和碳同位素組成的綜合分析表明：當時的大氣co2濃度略高於現在水平；化石種的碳同位素分餾值高於現存對應種，但水分利用效率低於現存對應種；這證明當時的氣候條件比當前更為溫暖濕潤。Our results suggested the accumulation of ft in muscle was not the only factor that affected " spectrum shift " during muscle fatigue. the decline of the firing rate of motor units, the synchronization of motor units and an inadequate cns drive may be the important mechanisms that attributed to the change of semg signal during isometric contractions
本研究認為肌肉疲勞過程中h ~ +濃度升高不是導致肌電功率譜曲線左移的唯一因素，運動單位放電頻率下降、中樞驅動減弱和運動單位活動的有序性或同步化可能是肌肉活動時肌電信號變化的一種重要機制。分享友人
