South as a Sight ‘南方’, from a branch to a necessity to World Literature

open access: yesJournal of Research in Social Science and Humanities, 2023
In the discussion and debates on the world literature system, methodologies and methods is a topic that is valued. Moretti and Apter have prominent different opinions on the adoption of digital or abstract data outside texts and contexts. The way Moretti views the world literature system is highly based on historiography and studies of the Annual ...

Using ICLAS to Absorption Spectrum of Harmonic Transition of 12CO2

open access: yes浙江大学学报. 农业与生命科学版, 2001
激光腔内吸收光谱技术(ICLAS)被发现以来,已被广泛应用于探测气体、液体、火焰以及等离子体中原子和分子的极弱吸收.其中的一个主要应用是研究分子高振动态的高分辨光谱.主要特征是灵敏度极高,可检测出少量分子微弱的光谱吸收,同时又可以对样品的吸收系数进行直接测量.

Study on absorption of simulated toluene-containing exhaust gas with emulsion liquid membrane(乳化液膜法处理模拟甲苯废气实验研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2010
使用以煤油为油相, Span-85为表面活性剂制取的乳化液吸收甲苯废气,考察了表面活性剂浓度、进口甲苯气体浓度及喷淋液气比对吸收效率的影响,实验在填料塔中进行.结果表明,表面活性剂浓度小于2%时,表面活性剂对吸收效果影响较小,而大于2%时,随着浓度的增大吸收效率有明显的减小;进口甲苯浓度在300~900 mg • m-3的范围内,吸收效率随着甲苯浓度的提高而提高;喷淋液气比在3.0~5.0 L • m-3范围内,吸收效率随着液气比的增大而提高.在选择合适的乳化液及喷淋液气比基础上,处理浓度为300 ...

Investigation on the acetic ether absorption of simulated exhaust gas by emulsion liquid membrane(乳化液膜法对模拟乙酸乙酯废气吸收的研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2011
针对水吸收法难于处理非(弱)水溶性有机废气的问题,以煤油为油相,失水山梨醇三油酸酯(Span-85)为乳化剂,制得水相/油相(W/O)乳化液膜,进行了吸收模拟乙酸乙酯废气的研究.结果表明:乳化液膜体系对乙酸乙酯废气吸收效率最高可达89%,1 h内吸收效率大于50%以上;低温、低表面活性剂体积分数和高废气质量浓度有利于提高吸收速率,在实验条件下存在最佳油水比1:1.

人工藻结皮形成过程中表土非降雨型水分吸收的变化情况 [PDF]

open access: yes, 2010
在干旱、半干旱地区,表土非降雨型水分吸收对于植物、生物结皮以及一些小型动物都起着非常重要的作用.本研究对库布齐沙漠中各种水分吸收类型进行了调查,并对人工结皮形成过程中水分吸收的变化进行了跟踪监测.结果发现,在实验区,从空气中吸收的水分占表土水分吸收量的25.07%~39.83%,其主要是通过水汽吸附机制进行.相比之下,表土从深层土壤吸收的水分更多,大约占到水分吸收量的60.17%~74.93%.人工结皮的形成促进了表土水分的吸收,但吸收水分的增加并非在接种后或结皮形成后立即表现出来,而是在结皮形成后 ...

Local hot gas survey based on OVII and OVI Absorption Lines [PDF]

open access: yes, 2016
活动星系核是研究本征于星系的中央黑洞和沿吸收线分布的吸收气体的直接环境的非常有效的工具。背景活动星系核的X射线光谱中可以探测到许多高度电离的本地吸收线,这些高度电离的吸收线可以帮助理解银河系内部和周围的热气体及其含量。三种最有可能的X射线吸收体的起源是:起源于盘,起源于广延的星系晕,起源于本星系群中热气体团际介质。理解银盘、厚盘和晕气体中在温度时产生气体的过程,是了解星系中气体的生命周期的重要因素。这些气体可能是由超新星、星风和掉落产生的,这些气体的存在可以追踪星系演化周围的环境 ...

The design and development for X-ray absorption spectrum measurement system [PDF]

open access: yes, 2016
组织光学是生物医学光子学的理论基础,组织光学特性参数的测量是其最重要也最艰难的任务,生物组织在不同生理状态下的成分会发生变化,健康与病变组织对光的吸收和散射不同,其光学参数也会随着光的波长而变化,测定组织在不同生理状态下的光学参数就可以对疾病进行诊断甚至前期诊断,进而及时进行治疗。制约组织光学发展的一个很重要的因素就是,所用光源(紫外到红外波段)对组织的穿透能力有限,无法实现较深部位的探测,而X射线具有良好的穿透能力,因此把组织光学推广到X射线范围不失为一种疾病诊断的有效途径 ...
