The results indicated that ( 1 ) " longxianhuosuan " presented more regular and more densely - arranged epidermal cells in its scapes than " gailiangsuan " ; ( 2 ) " longxianhuosuan " showed a lower stomata number but a larger stomatal aperture in its scape surface than " gailiangsuan " ; its scapes had a great number of secretory cells, which had a larger size and appeared earlier ; its scapes presented a smaller number of vascular bundles with smaller diameters ( 3 ) " longxianhuosuan " had polygonal cells in its scape pith with their intercellular space occupying a small proportion while " gailiangsuan " showed elliptical cells in its scape pith with their intercellular space occupying a high proportion
結果表明： （ 1 ） 「隴縣火蒜」比「改良蒜」蒜薹的表皮細胞形狀規則，排列緻密；角質層較薄； （ 2 ） 「隴縣火蒜」比「改良蒜」蒜薹表面的氣孔數量少，但開張度大；分泌細胞出現早、體積大、數量多；維管束數量少、直徑小； （ 3 ） 「隴縣火蒜」蒜薹髓細胞衛多邊形，髓細胞間隙率小，而「改良蒜」蒜薹的髓細胞呈橢圓形，髓細胞間隙率大。 -
The explosion soon followed ; the upper rock was lifted from its base by the terrific force of the powder ; the lower one flew into pieces ; thousands of insects escaped from the aperture dant s had previously formed, and a huge snake, like the guardian demon of the treasure, rolled himself along in darkening coils, and disappeared
在圓石被火藥的巨力一震，底部立刻松動了，下面的那塊墊石碎成了片，四散亂飛，一大堆小昆蟲從唐太斯先前所挖成的洞口裡逃了出來，一條象是保護寶藏的大蛇，游動著竄了出來，一會兒就不見了。 -
And we simulate the thing by different spatial frequency hartmann - shack wavefront sensor which is used in detecting the far field of laser beam, and we get the result that if magnitude of wave aberration is lower the dynamic range of sub - aperture of wavefront sensor, the more the spatial frequency of hartmann - shack wavefront sensor is, the more the accuracy of hartmann - shack wavefront sensor in detecting high frequency aberration is
並且波前像差在hartmann - shack波前傳感器子孔徑動態范圍之內，空間解析度高的hartmann - shack波前傳感器對高階像差波前探測時，其光束質量診斷精度高於空間解析度低的hartmann - shack波前傳感器的光束質量診斷精度。 -
Tensile stress will accelerate the carbonation of paste and mortar, which can be explained by the reason that shrinkage of carbonation is confined by tensile stress, and the function x = c0eantb can describe this process. carbonation can lower the total porosity and lessen the aperture in the cement paste
外部彎曲應力會加速水泥石和水泥砂漿的碳化過程，這可能與受拉區域碳化收縮受到限制有關：彎曲應力作用下水泥石和水泥砂漿的碳化動力學過程可用式x = c _ 0e ~ （ an ） t ~ b描述。 -
Poly - crystallization silicon thin film transistor ( p - si tft ) addressing liquid crystal display has been currently the research and development focus in the field of flat panel displays, as it is most feasible approach to high resolution, high integration and low power consumption as a result of its high aperture ration. there are less number interface of the crystal grain, lower metal impurity and higher mobility in the electric current director, the milc p - si tft has been the research focus in the fields of amlcd, projection display, oled etc. there are vast dangling bonds and bug
多晶硅薄膜晶體管（ p - sitft ）液晶顯示器可以實現高解析度、高集成度、同時有效降低顯示器的功耗，因而成為目前平板顯示領域主要研究方向;而以橫向晶化多晶硅為有源層的tft由於在導電方向有更少的晶界、更低的金屬雜質污染、更高的載流子遷移率而成為目前有源矩陣液晶顯示領域、投影顯示、 oled顯示等領域研究的熱點。 -
Aperture synthesis uses interferometry technique to improve the limitations set by antenna physical aperture while working at lower frequency. phase and amplitude calibration of the visibility samples must be carried out to compensate for system bias before measurement
綜合孔徑技術利用了以小口徑天線陣列合成大的觀測口徑的技術，解決了在較低頻率時天線物理口徑要足夠大才能得到期望的空間解析度的嚴重缺陷。 -
Further, if you close down the aperture diaphragm, you will observe that objectives of higher numerical aperture " grasp " more of these colored spectra than do objectives of lower numerical aperture
當光欄關小后，數值孔徑大的物鏡比數值孔徑小的物鏡產生的光譜狀點要多一些。 -
