Metallic zinc is an ideal anode material owing to its high theoretical capacity (819 mAh·g-1),ecofriendliness,low cost and high safety,which have driven fast development of Zn-ion batteries （ZIBs）.However,the practical application of current ZIBs is significantly restricted by irregular dendrite growth of zinc anode and the low working voltage （usuallyhe ethyl methyl carbonate （EMC） *** the corrosion interaction of Li+ions,Zn2+can be easily dissolved from Zn anode into the electrolyte to enable dendrite-free Zn2+plating/stripping at the ***,an aqueous carboxymethyl cellulose （CMC） binder is employed to generate a robust cathode electrolyte interface （CEI） layer on the graphite cathode,which renders ultrafast PF6--de-/intercalation into *** resultant Zn–graphite DIB operates stably at a high cut off voltage of 3.2 V,corresponding to an average output voltage of 2.2 *** 9000cycles at 5C,the high capacity retention of 95.9% can be achieved with～100%Coulomb *** on the mass of cathode material,our Zn–graphite battery exhibits ultrafast rate capability （60 C,a discharge time of 44 s） and high energy/power densities (208 Wh·kg-1at 214 W·kg-1;142 Wh·kg-1at 8692 W·kg-1),which holds great promise for large-scale energy storage.

商者,原为商人之磬。“商音”,乃五帝之遗声,是赫赫有名的商人之音。此《礼记·乐记》所谓“爱者宜歌”“肆直而慈爱”的“商声”,在《史记·乐书》里,被诬为“亡国之声”“靡靡之音”。战国时期“乐戒商音”,是因律学原因而不取“商声”,与政事无关。“清商”特色之音是太簇升高一律(半音)的夹钟商,后泛指汉魏六朝乃至隋唐之“清商”“清乐”,一度成为华夏正声。见之于古琴曲的“楚商”,是一个非常奇特的六声调式音阶,至今湖南仍有使用这个调式的民歌。“楚商”除调式音阶之义外,又泛指楚地之乐。楚地之清商、楚商、侧商等,成为魏晋隋唐中国音乐主调。迄今西北戏曲、民歌多使用楚乐侧调之“苦音”,也常常与“花音”交替使用。

OBJECTIVES To investigate whether negative remodeling(NR) detected by intravascular ultrasound(IVUS) of the side branch ostium(SBO) would affect in-stent neointimal hyperplasia(NIH) at the one-year follow-up and the clinical outcome of target lesion failure(TLF) at the long-term follow-up for patients with left main bifurcation(LMb) lesions treated with a two-stent *** A total of 328 patients with de novo true complex LMb lesions who underwent a 2-stent strategy of percutaneous coronary intervention(PCI) treatment guided by IVUS were enrolled in this study. We divided the study into two phases. Of all the patients, 48 patients who had complete IVUS detection pre-and post-PCI and at the 1-year follow-up were enrolled in phase Ⅰ analysis, which aimed to analyze the correlation between NR and in-stent NIH at SBO at the 1-year follow-up. If the correlation was confirmed, the cutoff value of the remodeling index(RI) for predicting NIH ≥ 50% was analyzed next. The phase Ⅱ analysis focused on the incidence of TLF as the primary endpoint at the 1-to 5-year follow-up for all 328 patients by grouping based on the cutoff value of *** In phase I: according to the results of a binary logistic regression analysis and receiver operating characteristic(ROC) analysis, the RI cutoff value predicting percent NIH ≥ 50% was 0.85 based on the ROC curve analysis, with a sensitivity of 85.7%, a specificity of 88.3%, and an AUC of 0.893(0.778, 1.000), P = 0.002. In phase Ⅱ: the TLR rate(35.8% vs. 5.3%, P her in the several NR(s NR, defined as RI ≤ 0.85) group than in the non-s NR *** The NR of LCx O is associated with more in-stent NIH post-PCI for distal LMb lesions with a 2-stent strategy,and NR with RI ≤ 0.85 is linked to percent NIH area ≥ 50% at the 1-year follow-up and more TLF at the 5-year follow-up.

本文对国内外报道过的畜禽粪便中常见雌激素的结构与性质、种类与含量、迁移特点和控制技术进行了总结归纳,对比不同种类、生长阶段畜禽粪便中雌激素的含量,发现动物类型、粪便特性、生理状态等因素导致雌激素含量存在较大差异,应根据不同雌激素的污染特征进行针对性治理.大量文献报道畜禽养殖场周围环境中检测出不同种类的雌激素,表明雌激素存在环境迁移风险,亟需建立风险评估体系以确保生态安全和人类健康.畜禽粪便中雌激素的控制技术有好氧堆肥、高级氧化和微生物降解,大量雌激素降解菌株已从不同环境中被分离并应用,而雌激素降解功能菌群和固定化菌剂在应对不同的环境压力、抵御污染物胁迫方面更具备应用潜力,菌群间的互作机制和雌激素的降解机制未来仍需深入探索和研究.
