本論文根據2bqm - 2型氣吸式精量鋪膜播種機的結構和工作原理，針對該機在實際播種中，吸種盤吸出的種子不能滿足準確地落入在膜上滾動開穴的鴨嘴內，並及時地排入到鴨嘴所成的穴孔內的設計要求，進行了一定的試驗研究，利用已建立的計算數學模型，設計新的試驗臺，改進排種器，使排種器的落種角度可以在一定的范圍內調整。The entering of the tourist and lamp - light gave much energy to furong cave and the temperature in the cave rised slowly. the different temperature between the outer and the inner as the air circulation, would make the cave wet seriously in the summer and dry in the winter. the density of co2 would go up because of piston - effect, cave depositing and the tourists " entering
遊人的進入和洞穴燈光的使用，給芙蓉洞內帶來了大量的能量，致使洞穴空氣升溫；由於動內外的溫度差和空氣的流通，開放的洞穴出現夏季高濕，冬季乾燥的變化現象； co _ 2的濃度會因為活塞效應、洞穴沉積和遊人的進入而升高，但影響最大的還是遊人，當遊客量較大的時候，洞穴co _ 2的濃度會隨遊人進入的數量增加而明顯升高，洞內co _ 2含量峰值記錄最高出現了6200ppm的記錄。These jade pillow from hundreds xiaoyu mosaic which is not only comfortable and cool, and good permeability, and the human body when it contacts will produce static electromagnetic field, so the head and neck multiple 10 points and sleep in the massage easily be stimulated
這類玉枕由數百片小玉鑲嵌而成，不僅舒適涼爽，而且透氣性好，當它與人體接觸時，會產生靜電磁場，使頭部與頸部的10多處穴位，在睡眠中得到輕松的按摩刺激。However, chakras and the aura can be analyzed, coded, and digitized since they are also energy forms
不過，穴道和靈氣也是以能量的模式存在，所以它們可以被分析編碼數字化。A transparent model is used to make the deflection jet board grounded on the inhere enlarged dimensions. the finished experiments are conducted to catch the flow rate directions and the situation of cavitation using a high - speed video cameras. in this paper, the finite element analysis and visualiation research of servo valve prestage jet flow field are carried out, which establish the theoretical foundation for mathematical model of servo valve prestage and the whole mathematical model of hydraulic servo valve
在對射流前置級驅動的伺服閥射流流場數值模擬的基礎上，用有機玻璃在偏導射流板原始尺寸的基礎上進行了擴大，製作了透明的偏導射流板，運用高速攝像機、液壓泵站等組成了可視化實驗系統，對射流流場的流速方向、渦流、氣穴等現象進行了多方位的觀測，並通過對接收管接收壓力的測試，對流場分析結果進行了驗證。Operation : the performer puts the hand on “ shen shu ” “ qi hai shu ” and “ da chang shu ” point and rubs crosswisely at same side to “ dai mai ” point, and then rubs through “ shen shu ” to other side of “ dai mai ” point repeatedly times
操作：施術者以手掌置於受術者一側「腎俞」穴、 「氣海俞」穴、 「大腸俞」穴處，先向同側橫摩到帶脈穴處，再通過兩側的腎俞穴摩動到對側帶脈穴處，往返進行數次。However, many of those studies focused on the structures of bearing itself. and few studies have been done on the gas cavity caused by the decrease of oil - pressure in the oiling system, which influences bearing
但是大多數研究都集中在軸承結構本身，對供油系統中由於供油壓力變化而造成油腔中出現氣穴現象對軸承特性影響的研究較少。Observation of drilling cores and casting - sections and the characters of pore structures and permeability of the matrix of the lower - ordovician carbonate in comparing with the lower limit of a reservoir for matrix reveal that the porosity, permeability, maximum pore diameter, saturation and median throat diameter in the matrix with undeveloped fissures, holes and solution pores are far lower than those of a reservoir limit although some micro - pores are developed in the matrix which therefore has no capacity of storing and producing oil - gas
摘要通過鉆井巖心和鑄體薄片觀察，根據下奧陶統灰巖基質的孔滲特徵和孔隙結構特徵，並與基質作為儲層的下限對照裂隙、洞穴和溶蝕孔洞不發育的灰巖基質，發現盡管有微孔隙的發育，但其孔隙度、滲透率、最大孔喉半徑、飽和度、中值喉道半徑等參數值遠低於儲層下限值，基本不具備儲集和生產油氣的意義。This article analyzes and arranges ancient documents such as neijing and so on, studies relationship among meridian system, points, zhangfu, qixue and symptoms, discusses their rationality and inner systems by mathematical method
