藥物經皮膚吸收進入體內的主要途徑有： （ 1 ）通過毛細血管通道；經過角質層轉運和皮膚深層轉運而吸收入血，阻隨血液循環到達人體各部位； （ 2 ）水合作用：角質層經水合作用后，可膨化呈多孔狀態，有利於藥物滲透； （ 3 ）熱刺激作用：可使局部血管擴張，血液循環加快，有利於藥物的穿透彌散和吸收。Through the special studies on impacts to atomizing and humidifying effect from such factors as the firing pin type, centrifugal structure, higher spraying pressure, less aperture, initial water temperature and original state of the air, some conclusions are obtained, such as : the centrifugal nozzle with firing pin type, high pressure and little aperture has bigger air eddy and atomizing angle. the spaying liquid has high velocity. the droplet is small, and the heat and mass transfer velocity is high
通過對撞針型結構、離心式結構、較高的噴水壓力、較小的噴嘴孔徑、噴水初溫及待加濕空氣初狀態對霧化加濕效果的作用原理的重點分析，得到：撞針型高壓小孔徑離心式噴嘴具有較大的空氣渦與霧化角，噴出的液體流速高、液滴小、水與空氣傳熱傳質速率高，撞針型結構提高了霧化加濕效率，高壓小孔徑的特點為霧化加濕提供了較大的能量，而噴水初溫的升高會減小水的粘性力和表面張力，從而優化加濕效果。In the experiment, we use the he - ne laser and the semiconductor laser as the source, record the bessel beam patterns behind the axicon by using a digital camera and a microscope, measure the radius of the bessel beam central spot by film - scanning and measure the effect of both the radius of the aperture and the open angle of the axicon on the maximum non - diffraction distance. the experiments show that a specific propagating range has constant power and the beam has a bessel - like distribution in this range. the results agree with the beam corresponding to a diffraction free beam
同時我們還採用膠片掃描的方法測量了無衍射光束的中心光斑尺寸，測量了不同光闌孔徑和不同稜角情況下的最大無衍射距離和傳播軸附近橫截面內微小光孔中的光強，實驗結果顯示當激光光束經過軸棱錐轉換後有一段距離功率變化很小，且分佈近似貝塞爾分佈，符合無衍射光束的特性;經過聚焦后，呈現三維分佈中空的光束bottlebeam ，實驗結果與理論分析基本吻合。The radar which is embedded on platform sidelooking, but the platform will be disturbed by airflow inevitably. so, the radar will have a small sloping angle, thereby, the doppler centroid that is not zero and doppler frequency rate need to be estimated from the raw echo data in order to focus in azimuth commendably
場景成像的合成孔徑雷達一般是正側視放置，但是載機不可避免的要受到各種擾動影響，雷達會有一定的斜視角，從而導致了多普勒中心頻率不為零，多普勒調頻斜率也隨著雷達斜視角改變。The non - singular extended 2 x 2 jones matrix is deduced to give the precise description of angular property under normal and oblique incidence. consequently, we draw a very important conclusion that the pif is insensitive to the incidence, and has a large numerical aperture
詳細推導了適用於偏振干涉濾光片角度特性分析的無奇異點擴展2 2瓊斯矩陣，對正入射和斜入射下的偏振干涉濾光片光學特性進行了精確描述，並分析出偏振干涉濾光片具有大數值孔徑的重要特性。Due to restriction with the array aperture transition time, traditional phased array radar works under relative narrow signal bandwidth, so this restricts the application of phased array radar in the field where high performance is demanded. however, optically controlled phased array radar ( ocpar ) adopts the photoelectron technology, counteracts the aperture transition time via the method of optical true time delay ( ottd ), so it can realize wide instantaneous bandwidth and squint - free operation ; meanwhile, it can realize the miniaturization of phased array radar and has super anti - electromagnetism interference capability
而光控相控陣雷達採用光電子技術，通過光實時延遲的方法來抵消孔徑渡越時間，可以實現相控陣雷達的寬帶寬角掃描;同時也可以使得相控陣雷達小型化，並具有強的抗電磁干擾的能力;另外，由於光纖傳輸具有損耗低、頻帶寬等固有優點，採用光纖連接雷達天線和雷達控制中心，可以使兩者的距離較採用同軸電纜有較大的提高，更有利於保護雷達控制中心。Diameters of counterbores for hexagon socket head cap screws and screws with cheese head or pan head ; manufacturing dimensions
六角凹頭有帽螺釘和圓頭螺釘或大柱頭螺釘用沉孔直徑Some valuable conclusions are summarized by theoretical analysis and simulation experiments : from the side of signal processing, pulse jamming can be deleted by the method of time - domain sliding window accumulation and can be restored by interpolative prediction. ; gauss white nose can be attenuated while jamming disperse point - target by the method of time - frequency analysis in time - frequency domain. ; radio frequency noise jamming can be deleted by the method of average range frequency spectrum and notching in frequency domain
通過大量的理論分析和模擬實驗，得到了一批具有一定價值的結論：從信號處理的角度出發，對于脈沖式干擾，能夠運用時域滑動窗口積累的方法去掉，並且通過預測插值得到較好的恢復；對于高斯白噪聲干擾，在時頻變換域內應用時頻分析方法可減小其對分散點目標的干擾；對于射頻噪聲，通過平均距離頻頻法和頻域陷波的方法可以去掉；從改變合成孔徑雷達系統角度出發，類似雙基地雷達能夠避免各種干擾，對發射信號進行調幅，調相以及改變調頻斜率都是較好的抗干擾方法。Moreover, automatic aperture size selection ( single frame or double frame ), frame indexing, single corner positioning, and auto exposure control, individual functions that work together to improve productivity and image quality. automatic reduction and focus ensures sharp, correctly sized images every time
