目的分析乳腺核磁共振(magnetic resonance imaging,MRI)简易序列(AP)对乳腺肿瘤的诊断的效果。方法选取2019年1月—2021年12月于邳州市中医院接诊的76例临床怀疑乳腺癌的乳腺肿瘤患者为研究对象,均行MRI检查,以术后病理结果为金标准,对比分析常规序列(FDP)、简易序列(AP)的诊断效果。结果经术后病理证实,51例患者为恶性乳腺肿瘤,25例患者为良性乳腺肿瘤。AP诊断乳腺肿瘤BI-RADS类型以及TIC类型敏感度、特异度、阳性预测值、阴性预测值与FDP比较,差异无统计学意义(P>0.05);AP扫描时间、阅片时间为(9.19±0.53)、(10.15±2.57)min,较FDP的(19.91±0.63)、(21.68±4.21)min明显缩短,差异有统计学意义(P<0.05)。结论乳腺MRI检查中AP诊断乳腺癌的价值与FDP相近,但扫描时间缩短,诊断效能更高,应用优势明显。

We theoretically investigate the spin resolved Friedel oscillation （FO） and quasiparticle interference （QPI） in graphene induced by an Anderson *** the impurity becomes magnetic,the resulted FO becomes spin dependent,which gives rise to a local magnetic moment oscillation with an envelop decaying as r-2in real space in the doping ***,at half filling,the electron density and local magnetic moment will not oscillate but decay as *** spin resolved FO has both sublattice and spin ***,the local magnetic moment decay at half filling only occurs at one sublattice of graphene,which is quite like the phenomenon observed in the STM experiment (***ález-Herrero et al.,Science 352,437 （2016）).We further give an analytic formula about such spin dependent FO based on the stationary phase ***,we study the interference of quasiparticles around the magnetic impurity by calculating the spin dependent Fourier-transformed local density of states （FT-LDOS）.Our work gives a comprehensive understanding about the local magnetic moment oscillation around an Anderson impurity on graphene.

提出了求解近水面有限长谐振动圆柱远场声学特性的解析方法。首先，基于镜像原理，以假定虚源模拟自由液面影响；再结合Graf加法定理，将虚、实源各声压项进行合并；声压转换到波数域后，将得到其简洁显示表达式；最后，重要指标——远场辐射声压则利用稳相法进行求取。针对不同声学成分的分类形式，建立了对应计算模型，模型可用于深入研究自由液面影响及结构表面互散射机理。研究结果表明：自由液面的影响可归纳总结为类偶极子效应，且该效应对辐射声与散射声的计算结果均有显著影响，但二者除相似传播规律外还存在不可忽视的相位差；散射声压随散射次数增大将以固定倍率衰减，且衰减速率与圆柱壳浸没深度成正比，但与壳体表面谐振动激励频率成反比。
