解釋
光截面-
However, after co - porphyrin is kept in 1, 4 - dioxane for two weeks, excited by 488nm, it shows apparent reverse saturable absorption and enhanced optical limiting effect, which can be attributed to the absorption cross - section change of exicited state in co - porphyrin derived probably from the production of co ( iii ) - porphyrin due to oxidation of 62 on co ( ii ) - porphyrin
鈷卟啉（ co （ ） tpp ）對457 . 9nm 、 514 . 5nm和488nm波長的光都具有限幅作用，並對457 . 9nm波長的光呈現明顯的飽和吸收。放置半個月的樣品在488nm波長光的作用下表現出明顯的反飽和吸收，並且其光限幅特性在488nm處表現出增強效應。 -
Because the cross - section of the oversized rib waveguide we fabricated by wet - etching was trapeziform, we analyzed the transmission of oversized rib waveguide by combining effective refractive - index method. the influence of some factors on the optical transmission loss, such as material structure, the height of rib waveguide, and the thickness and refractive index of waveguide layer and up - layer of polymer material, was analyzed
因為濕法腐蝕工藝製作的反脊波導橫截面是梯形狀的，因此論文中採用了一種簡單有效的方法，即有效折射率法，對梯形反脊波導的光傳輸損耗特性進行了分析，同時考慮金屬電極產生熱場對脊波導傳播特性的影響。 -
Therefore we could carry out numerical calculations and obtain the reaction cross section, the nucleon removal cross section and the momentum distribution in the scattering of a halo nucleus with any types of density distributions. we compare the reaction cross sections calculated in the few - body glauber theory and the optical - limit glauber theory
進一步對27p 、 28p反應截面的研究分析表明，考慮核芯2751的增大可以很好解釋實驗測量得到28p反應截面的增大，而要解釋27p反應截面的異常增大，需要同時考慮核芯2 「 si增大和具有非常彌散空間分佈的2s ， ， :態暈核子。 -
Great attention has been paid on the study of random surfaces in many scientific and technological fields such as the growth fronts of thin films, surfaces of fabricated optical devices, and the fractured cross - section of materials, etc.
粗糙隨機表面統計特性的研究是一個多年來倍受關注的問題，這一問題在如動力學的材料生長界面，由大的沖擊而產生的斷裂面，光學元件設計等諸多物理領域具有重要的意義。 -
Optical fiber process tomography ( ofpt ) is a new technology in the field of optical fiber sensor ( ofs ). the probe of ofpt is small, safe, free of electromagnetic interference and has high sensitivity in low - density medium case same as ofs, more important and different is that it can detect the medium distribution and contents of the cross - section to be investigated simultaneously, which makes ofpt show potential and extensive applications in petroleum, chemical, energy, medicine, food and sanitation fields to control product quality, realize safe production and reduce the cost
光纖過程層析成像是光纖傳感領域的一門新型技術，具有光纖傳感器的測量低濃度物質解析度高、體積小、抗電磁干擾以及可以進行分散式測量的共同優點和可以同時測量物質截面內部結構的獨特優點，在多相流動廣泛存在的石油、化工、能源等工業部門和醫療、衛生、食品等領域具有廣泛的應用前景，對監控產品質量、降低成本以及保證生產安全具有非常重要的意義。 -
The results indicate that the peak intensity of transmission beam is limited, and the cross - section intensity distribution is approximately flat - topped super gaussian, which shows the optical limiting effect of sbs
結果表明，透射光束截面光強呈現出近似平頂的超高斯分佈，光強峰值被限制，顯示出受激布里淵散射的空間光限幅效應。
