The 808-nm vertical cavity surface emitting laser(VCSEL)with strained In0.13Ga0.75Al0.12As/Al0.3Ga0.7As quan-tum wells is designed and fabricated.Compared with the VCSELs with Al0.05Ga0.95As/Al0.3Ga0.7As quantum wells,the VCSEL with strained In0.13Ga0.75Al0.12As/Al0.3Ga0.7As quantum wells is demonstrated to possess higher power conver-sion efficiency(PCE)and better temperature stability.The maximum PCE of 43.8%for 10-μm VCSEL is achieved at an ambient temperature of 30℃.The size-dependent thermal characteristics are also analyzed by characterizing the spec-tral power and output power.It demonstrates that small oxide-aperture VCSELs are advantageous for temperature-stable performance.

中度干扰假说(IDH)即在中等程度的干扰下物种会维持更高的生物多样性.本研究以辽河流域为例,验证大型底栖动物群落在中等干扰下是否会出现最高的物种丰富度(即呈现单峰曲线).结果显示,化学需氧量和电导率是影响底栖动物群落分布的主要因子,且物种丰富度与化学需氧量和电导率拟合后均呈现出单峰曲线,且P<0.05,符合IDH.该结果可为合理的进行水域环境调控以及维持水生生物多样性提供参考.
对2019年-2021年7月-8月北戴河近岸3海里范围海域水母暴发情况进行监测巡视及捕捞,并对调查结果进行统计分析.调查结果显示北戴河近岸海域水母种类主要有海月水母、沙蜇、海蜇、白色霞水母四类.近三年来海月水母暴发期缩短,捕捞量有减少趋势,白色霞水母暴发期较长,捕捞量逐年增加,成为水母捕捞重点防治对象.水母总捕捞量2019年最多,2020年最少,呈波动趋势.并提出水母暴发的防控建议,以期为北戴河近岸海域水母暴发研究提供参考.
本研究对漳卫新河河口地区的环境因子与水生生物群落结构进行调查,本次调查漳卫新河地区共鉴定底栖动物30种、甲壳动物23种、鱼类20种.运用主成分分析对河口处环境因子进行分析,结果显示各环境因子在该流域响应都比较明显.通过计算水体有机污染物综合指数、水体富营养化状况指数、水体环境质量与主要污染物和生物多样性指标对漳卫新河河口的水域环境质量状况进行评估,结果显示漳卫新河河口处有机物污染状况整体呈现中度污染水平,水体呈现富营养化状态,水域环境质量为中度污染.整体上影响漳卫新河污染的主要污染源是总氮和高锰酸盐含量.
We systematically investigate the power distribution characteristics of microjets generated by prismatic scatterers with different shapes at sub-THz region(λ=8.57 mm).Among these prismatic scatterers,the hexagonal-type one shows better focusing feature th
The quantitative investigation of parameters in the renegerator is essential for the optimization of thermoacoustic de-vices,while the majority of the previous research only considered parameters of the working field,working gas and the hydraulic radius.B
北部湾休闲渔业有别于内陆休闲渔业,依靠近海资源,利用休闲渔船从事垂钓、捕捞、采集等与渔业相关的休闲活动.本文通过对北部湾休闲渔业发展现状、存在问题进行研究,探索北部湾休闲渔业发展新途径.
We experimentally engineer a high-spectral-purity single-photon source using a single-interferometer-coupled silicon microring.By the reconfiguration of the interferometer,different coupling conditions can be obtained,corresponding to different quality fa
2022年已悄然开启,在飞逝的时光里,我们看到的、感悟到是一个坚韧不拔的中国养猪业,这里有养猪人日日夜夜的坚守,有赓续传承的事业.2022年养猪业应如何布局?养猪人何去何从?大家都在拭目以待.我想真正的清醒就是知晓自己在行业所处的位置和当前行业的形势,既不谵妄,也不松懈.
The optical Ramsey spectrum is experimentally realized in an 87 Sr optical lattice clock,and the measured linewidth agrees well with theoretical expectation.The coherence time between the clock laser and the atoms,which indicates the maximum free evolutio
Direct weak or strong measurement of quantum wave function based on post-selections has been widely explored;however,the efficiency of the measurement is heavily limited by the success probability of post-selection.Here we propose a modified scheme to dir
