关键词： 测试   振荡提取   氧弹燃烧   离子色谱   可吸附有机卤化物   纺织品  

摘要： 采用振荡提取、氧弹燃烧以及离子色谱定量检测等步骤测定纺织品中可吸附有机卤化物(AOX)。将纺织品加入到适量的提取液中,通过振荡使AOX充分溶解并富集在活性炭上,使用酸性硝酸钠溶液处理以去除无机卤化物。采用氧弹燃烧方式对可吸附AOX的活性炭进行裂解、燃烧及气化,采用离子色谱法测定。结果发现,在标准溶液0.02~2.50mg/L范围内,Cl^(-)、Br^(-)和I^(-)的线性相关系数R2在0.999以上,AOX的定量限为7.58~8.67mg/L,在不同的加标水平下AOX的平均回收率在83.1%~98.1%,相对标准偏差RSD(n=7)为2.1%~5.9%,表明方法具有良好的回收率和精密度。

关键词： 内曲线马达   U形槽   响应面法   扭矩脉动   减振降噪  

摘要： 扭矩脉动是导致内曲线马达产生振动和噪声的主要原因之一。为降低扭矩脉动,设计了U形阻尼槽配流盘;以马达柱塞腔流量压力脉动为基础,建立了阻尼槽配流面积变化及马达扭矩脉动的理论模型。基于AMESim平台建立了内曲线马达动态仿真模型,并采用响应面法对U形阻尼槽进行了参数优化。结果表明:扭矩脉动与U形槽结构参数间存在多种影响机制;相比无阻尼槽,优化U形槽后的配流盘可以使马达扭矩脉动程度降低44.55%。

摘要： Patients with complex valvular heart disease (VHD) should be evaluated by a multidisciplinary heart team (HT). In low- and middle-income countries, referral practices are more variable, permitting any physician to refer patients directly to a cardiac surgeon without prior formal evaluation by a cardiologist with expertise in VHD.

关键词： stars   novae-cataclysmic variables-history and philosophy of astronomy-stars   dwarf novae-stars   evolution  

摘要： In recent astronomical discussions, attempts have been made to link the known dwarf nova Z Cam to historical celestial events, particularly the “guest star” phenomenon reported in China in 77 BCE. Despite other suggestions and the problems with regard to the location of the event in 77 BCE, its identification with Z Cam is used in the Variable Star Index of the AAVSO and in several research papers that aim to derive knowledge on the evolution of cataclysmic variables. Through the reconstruction of the super-constellation of the Purple Palace in the Han Dynasty, we found that Z Cam is actually located outside this enclosure, contradicting the records of the 77 BCE guest star being “within the Purple Palace.” With newly found text versions of the guest star in 77 BCE, we narrowed down the position given therein. Combining with a new analysis of accompanying divination text leads to the conclusion that this guest star was actually a comet. Finally, through meticulous examination and comparison, we conclude that the guest star of 369 CE appears the most plausible candidate for Z Cam's historical counterpart, aligning with both textual evidence and modern astronomical observations.
