中文拼音 [shùpiānxié]
束偏斜
英文
beam deflection-
In this paper, dual - beam transmission problem that possess to a certainty included angle and gains the nonlinear schrdinger coupled equation ( nnlse ) in self - defocusing media is discussed
摘要自散焦介質中雙光束斜入射耦合能發生光束偏轉，通過數值模擬發現在非線性折射率不是均勻分佈時光束偏轉能降低抽運光功率並且偏轉角度不減小，在相同的功率條件下，能產生更大的偏轉。This paper designs an optical system based on above to measure the small angle of the laser beam. a non - polarized beam splitter ( npbs ) is used to split the incident beam into two branches, and a rhombic prism agglutinated by two right - angle prisms is placed to realize total internal reflection twice in each branch. it not only improves the measurement sensitivity and linearity, but also increases antinoise ability by the differential optics
本文正是基於這一原理設計了測量光束微小偏轉角的光路系統，用消偏振分光棱鏡將入射光分為兩路，並在兩路分別用兩個直角棱鏡組成的斜方棱鏡來實現兩次全內反射，不但提高了測量靈敏度和線性，還利用差分光路的特點提高了抗干擾能力。And it should be linear polarization in s direction by analyzing the relations between the reflection, absorption loss of optical thin film at oblique incidence and the polarization state, and at this time the brewster window made of very low - absorption material can be used
通過對斜入射高反射鏡反射率、吸收損耗與光束偏振特性間的關系進行分析，表明諧振腔內的本徵振蕩最好應為s方向的線偏振光，這樣光束輸出窗口還可採用布儒斯特窗。Therefore, it is necessary to take suitable measures to alleviate the influence of flow deflection on the heat - transfer performance of the condenser
在管束布置時，應當採取相應措施減小流場偏斜對凝汽器傳熱特性的影響。The numerical results show that because of the temperature variation of cooling water along its flow direction the heat load of the second - pass tube bundle is lower than that of the first - pass tube bundle, which brings about the steam flow deflection and then the deterioration of heat transfer
計算結果表明，由於冷卻水溫度沿冷卻水流動方向的變化，第二流程管束的熱負荷明顯小於第一流程的，並使蒸汽流動?生側向偏斜，導致流動與傳熱特性的惡化。分享友人
