为了采集铝合金点焊过程中的压力变化量,实现实时监测熔核状态,提高焊点质量,设计了一种铝合金点焊压力采集的滤波系统。第一步,设计采集电路,实现对压力信号的实时采集和电平转换;第二步,通过对压力信号干扰源的分析,设计硬件滤波和软件滤波相结合的方法,以解决压力信号受干扰的问题。实验结果表明,采用本系统得到的压力波形变化平稳,能够准确反映焊接过程中的压力变化和熔核状态。采用本系统后焊点熔核直径平均值提高了10%,而且焊点无裂纹,气孔也较少。

使用OM、SEM和EDS等手段,研究了第三代镍基单晶高温合金DD33不同V型缺口取向([100]、[210]和[110])片状试样从室温到不同上限温度(1000℃、1100℃和1200℃)的热疲劳过程中裂纹的萌生和扩展行为。结果表明,在三种上限温度,DD33合金的热疲劳性能均出现明显的各向异性。在三个上限温度[100]取向试样均表现出最好的热疲劳性能;上限温度为1000℃和1200℃[110]取向试样的热疲劳性能最差,上限温度为1100℃[210]取向试样的热疲劳性能最差。不同取向试样的热疲劳裂纹的萌生和扩展行为,均呈现出一定的晶体学取向规律。热应力、氧化以及滑移系的开动,导致不同取向试样裂纹的扩展速率不同。

反馈是教学的关键环节,有助于激发学习内动力,促进学习投入。但反馈是否生效取决于学习者的反馈投入。近年来,针对学习者在二语写作教学反馈的被动投入,国内外研究开始聚焦反馈与学习投入的相关性,但这些研究多脱离真实教学情境研究单种反馈对学习投入的影响。通过对学生成绩、学生写作文本修改稿及访谈等数据分析人机混合反馈对本科生学术英语写作的影响,发现:人机混合反馈对反馈投入有显著影响。研究结果可对学术英语写作教学及学习投入研究提供借鉴与参考。

BACKGROUND Previous research has highlighted correlations between blood cell counts and chronic liver ***,the causal relationships remain *** To evaluate the causal effect of blood cell traits on liver enzymes and nonalcoholic fatty liver disease(NAFLD)*** Independent genetic variants strongly associated with blood cell traits were extracted from a genome-wide association study(GWAS)conducted by the Blood Cell ***-level data for liver enzymes were obtained from the United Kingdom *** data were obtained from a GWAS meta-analysis(8434 cases and 770180 controls,discovery dataset)and the Fingen GWAS(2275 cases and 372727 controls,replication dataset).This analysis was conducted using the inverse-variance weighted method,followed by various sensitivity *** One SD increase in the genetically predicted haemoglobin concentration(HGB)was associated with aβof 0.0078(95%CI:0.0059-0.0096),0.0108(95%CI:0.0080-0.0136),0.0361(95%CI:0.0156-0.0567),and 0.0083(95%CI:00046-0.0121)for alkaline phosphatase(ALP),alanine aminotransferase(ALT),aspartate aminotransferase,and gammaglutamyl transferase,*** predicted haematocrit was associated with ALP(β=0.0078,95%CI:0.0052-0.0104)and ALT(β=0.0057,95%CI:0.0039-0.0075).Genetically determined HGB and the reticulocyte fraction of red blood cells increased the risk of NAFLD[odds ratio(OR)=1.199,95%CI:1.087-1.322]and(OR=1.157,95%CI:1.071-1.250).The results of the sensitivity analyses remained *** Novel causal blood cell traits related to liver enzymes and NAFLD development were revealed through Mendelian randomization analysis,which may facilitate the diagnosis and prevention of NAFLD.
