AB2O4-type spinels with low relative permittivity（εr） and high quality factor（Q × f） are crucial to high-speed signal propagation systems. In this work, Zn2+/Ge4+co-doping to substitute Ga3+in ZnGa2O4was designed to lower the sintering temperature and adjust the thermal stability of resonance frequency simultaneously. Zn1+xGa2-2xGexO4（0.1 ≤ x ≤ 0.5） ceramics were synthesised by the conventional solid-state method. Zn2+/Ge4+co-substitution induced minimal variation in the macroscopical spinel structure, which effectively lowered the sintering temperature from 1385 to 1250 ℃. All compositions crystallized in a normal spinel structure and exhibited dense microstructures and excellent microwave dielectric properties. The compositional dependent quality factor was related to the microstructural variation, being confirmed by Raman features. A composition with x = 0.3 shows the best dielectric properties with εr≈ 10.09, Q × f ≈ 112,700 THz, and τ_f ≈-75.6 ppm/℃. The negative τ_f value was further adjusted to be near-zero through the formation of composite ceramics with TiO2.

According to the differences in ore-controlling structural systems and the characteristics of host rocks, textures and structures of ores and mineral associations of ores, quartz vein-type gold deposits in the Rushan area can be divided into the Rushan and Tongling styles. Rushan style gold deposits, occurring in the Kunyushan complex, include Rushan, Tangjiagou and Tongxishan gold mines. They are distributed along four NNE-trending and sinistral, compresso-shear faults with a right stepping array. A prominent characteristic of the gold mineralization is that the orebodies in neighbouring gold deposits distributed in a single ore-controlling fault zone take opposite pitches. Study of the locating structures of the quartz vein gold deposits shows that the Rushan-style gold deposits are characterized by NNE and NE zoning. Therefore, the intersections of the NE direction of the known gold deposit and the neighbouring NNE-trending fault zones are favourable for looking for gold deposits, and the ends of the curving segments of sinistral and right-stepping faults are favourable for looking for large gold deposits. Tongling-style gold deposits occur in the Sanfosan porphyritic monzonitic granite. Emplacement of gold deposits is controlled by arcuate and radiate structures formed during the intrusion of the Sanfoshan porphyritic monzonitic granite; the radiate faults controlled the distribution of orebodies and the arcuate faults controlled the pitch of the orebodies.

目的分析强直性脊柱炎(AS)患者合并高尿酸血症(HUA)的临床及实验室特征,探索AS合并HUA的可能危险因素。方法收集2014年1月至2022年6月于我院就诊的AS患者临床资料,根据血尿酸(sUA)浓度分为高尿酸(HUA)组及非高尿酸(NHUA)组,比较两组临床与实验室指标的差异。结果①402例AS患者最终被纳入此横断面研究,其中HUA组93例,NHUA组309例;男性AS患者发生HUA的发生率显著高于女性(28.62%vs.8.92%,P0.05)。③血沉(ESR)、血小板计数(PLT)、中性粒细胞百分比(GR%)、肾小球滤过率(eGFR)、Bath强直性脊柱炎疾病活动指数(BASDAI)、Bath强直性脊柱炎功能指数(BASFI)评分在HUA组均显著低于NHUA组(均P<0.05);而肝胆代谢相关指标、胱抑素C(CysC)和血肌酐(Crea)在HUA组则显著高于NHUA组(P<0.05)。④sUA水平与ESR、GR%、BASDAI和BASFI评分均呈显著负相关(均P<0.05)。⑤Logistic回归分析发现,男性、高Crea和低eGFR是AS患者发生HUA的危险因素,而高龄发病和高ESR则可能是AS患者发生HUA的保护因素。结论AS合并HUA的发生率较高,尤其是男性、低龄发病的AS患者,需加强sUA的定期监测;合并HUA的AS患者表现出相对较低的疾病活动度,sUA可通过氧化应激等促发AS患者炎症的自我防护,但具体的机制有待进一步研究。

The igneous rocks in southeastern Hubei Province are mainly Yangshanian syntectic intermediate-acid magrnatic series. According to their regional geological setting, characteristics of ithochemistry, isotope,REE and metallogenic type, the syntectic intermediate-acid magmatic series can be further divided into two subseries: diorite-quartz monzonite magmatic subseries with high content of alkali and sodium, and quartz diorite - granodiorite magmatic subseries with low content of alkali and high potassium. They controlled the distribution and type of iron and copper ore deposits in this area
