基础教育外语教学研究 2015年第8期 58-64页

作者： abdullah hassan

*** In language planning, scholars typically have to choose a particular language over one or several others, to be promoted as a national *** then have to persuade and convince not only state executives and leaders, but also those involved at all levels of language use, regarding forms or rules to be cultivated, and eventually balance benefits against cost.

目的:目前国内外有很多学者在进行突发性聋预后相关因素研究。但由于缺乏高质量的临床研究和循证医学证据,突发性耳聋的预后因素尚不清楚,存在较大的分歧。本研究旨在探讨各种相关因素对突发性聋患者预后的影响,为相关诊断及综合治疗提供一定的依据。方法:回顾性分析2016年8月018年1月期间由吉林大学第一医院耳鼻咽喉头颈外科耳内科组诊断并收治的的219位突发性聋患者,收集可能影响其预后的相关因素,如性别、年龄、患耳侧别、有无缺陷、听力曲线类型,伴随症状(耳鸣、耳闷、头晕或眩晕),有无基础疾病(高血压、糖尿病)和治疗时间与治疗效果的关系,探讨以上因素与疗效的关系。应用SPSS22.0软件对可能影响突发性聋预后的相关因素进行统计学分析。结果:对诊断为突发性聋的219位患者的临床资料进行相关回顾性分析。在所有患者中,有211位患者诊断为单耳突发性聋,8位患者出现双耳感音神经性聋。根据单因素分析显示:男性较女性相比预后较差,但是不同性别对预后疗效无明显统计学意义,P>0.05;不同年龄组间的治疗效果有统计学意义,P0.05;患耳侧别对于预后疗效有统计学意义,P0.05。而在多因素分析中显示,年龄、不同类型的感音神经性聋以及伴随症状(耳闷感)是影响预后疗效的独立危险因素。结论:1、突发性聋患者中,听力下降程度越重预后越差;伴有耳闷胀感、眩晕或头晕及高血压可能影响其预后,但在多因素分析中头晕和高血压无统计学意义。2、年龄、不同的听力曲线类型、伴随症状(耳闷感)能够影响预后疗效,多因素分析中也证实预后的独立危险因素;男性患者较于女性患者预后不良,20-29岁的患者较年龄高于50的患者相比预后较好;低频听力下降的患者与平坦型、全频下降型患者相比预后较好;不同患耳的预后具有统计学意义。

本论文的主要目的是彻底研究制度质量对巴基斯坦出口绩效的影响,问题在于巴基斯坦的出口绩效是消极的,制度质量的重要性也受到了审查。在这项研究中,详细研究了巴基斯坦的体制质量,并审查了从历史至今的体制政策。在研究中,因变量为输出变量,自变量为制度质量(IQ)、汇率(ER)、人力成本(HC)、国内生产总值(GDP)和外国直接投资(FDI),以分析1984-2017年期间的这些变量数据,因变量数据(即出口数据)则是从世界发展指标收集的,自变量数据则是来源于国家风险指数。自回归分布滞后模型被用来做这项测试。本研究的结论和假设是,我们从变量中的大道的结果是显著的,制度质量与出口绩效之间存在这巨大的关系。从巴基斯坦的角度来看该国的机构薄弱,而巴基斯坦的出口表现也很差。

Nanosecond pulse and dual-wavelength Q-switched 1.5 μm fiber laser using MAX phase Cr2TiAlC2 saturable absorber

引用

Optoelectronics Letters 2025年第1期21卷 7-12页

作者： Ahmed Shakir AL-HITI Hiba hassan Department of Electrical Engineering Faculty of Engineering University of Anbar Department of Laser and Optoelectronics Engineering University of Technology-Iraq

We demonstrated a new type of MAX phase material, chromium titanium aluminum carbide（Cr2TiAlC2） polymer film, to generate a passively Q-switched erbium-doped fiber laser（EDFL）. The film thickness was measured to be around 45 μm, which was fabricated using the embedding method with polyvinyl alcohol（PVA） polymer as hoster. The saturable absorber（SA） film demonstrates a dual-wavelength passively Q-switched EDFL which operates at 1 531 nm and 1 560.19 nm, respectively. The Q-switching pulse duration could be varied from 2.46 μs to 770 ns, while the repetition rate varied from 92.76 kHz to 106.6 kHz with an increasing input pumping range from 154 mW to 300 mW. The maximum output power and pulse energy of 15.05 mW and 141.18 nJ were obtained at the maximum input power of 300 mW, respectively.
