All-solid-state Li batteries(ASSLBs) with solid-state electrolytes(SSEs) are exciting candidates for nextgeneration energy storage and receive considerable attention owing to their reliability. Halide SSEs are promising candidates due to their excellent stability against 4 V-class layered cathodes. Compared with Li3InCl6or Li_(3)ScCl_(6), the low ionic conductivity of Li_(2)ZrCl_(6)(LZC) is a challenge despite its low raw-material cost. Herein, we report a family of Li-Richened chloride, Li_(2+2x)Zr_(1–x)MxCl_(6), which can be used in highperformance ASSLBs owing to its high ionic conductivity(up to 0.62 mS cm^(-1)). The theoretical(ab initio molecular dynamics simulations) and experimental results prove that the strategy of aliovalent substitution with divalent metals to obtain Li-Richened LZC is effective in improving Li^(+)conductivity in SSEs. By combining Li_(2.1)Zr_(0.95)Mg_(0.05)Cl_(6)(Mg5-LZC) with a Li–In anode and a LiCoO_(2)cathode, a room-temperature ASSLBs with excellent long-term cycling stability(88% capacity retention at 0.3C for 100 cycles) and highrate capability(121 m A h g^(-1)at 1C) is reported. This exploratory work sheds light on improving the Li^(+)conductivity of low-cost LZC-family SSEs for constructing high performance ASSLBs.

汉南长江干堤某堤段管涌险情整治工程受到西气东输穿堤管线影响,全封闭防渗墙被分隔而不连续导致端部出现绕渗问题。针对防渗墙未封闭段渗流控制问题,提出防渗排水相结合的渗流控制思路,堤防主体采用全封闭防渗墙防渗,西气东输管线穿堤段采用减压井排水控制地下水头。为综合评价防渗排水相结合的渗流控制措施效果,基于MODFLOW构建了汉南长江干堤三维渗流数值模型,通过数值模拟方法对比分析了无渗控措施、仅采用全封闭防渗墙以及考虑防渗墙端部绕渗影响下防渗墙与减压井相结合的渗控措施对堤防渗流场状态及渗透稳定的影响,研究了减压井井口高程对汉南长江干堤渗流控制效果的影响。研究结果表明:天然状态下和仅采用全封闭防渗墙措施时,汉南长江干堤堤内薄弱处汛期存在渗透破坏风险,且仅采用防渗墙措施时防渗墙缺口处绕渗明显。在防渗墙未封闭段设置减压井,采用全封闭防渗墙与减压井复合措施后,堤防渗流控制效果受减压井井口高程影响显著。当井口高程逐渐降低,堤内压力水头差随之增大,减压井汇流能力增强、排水减压效果明显提升,建议在设计阶段充分考虑减压井井口高程影响。

Objective:To discuss the role of 3D-computed tomography angiography(3D-CTA) technology in reducing injuries of large meningioma ***:3D-CTA preoperative examinations were done in 473 patients with large meningioma(simulated group).The images were analyzed by 30 post-processing *** observing the major intracranial blood vessels,venous sinus,and the compression and invasion pattern in the nerve region,assessing risk level of the surgery,simulating the surgical procedures,the surgical removal plan,surgical routes and tumor blood-supplying artery embolisation plan were *** hundred and fifty seven large meningioma patients who didn’t underwent 3D-CTA preoperative examination served as control *** incidence of postoperative complications,intraoperative blood transfusion and the operation time were compared between these two ***:Compared with the control group,the Simpson’s grade 1 and 11 resection rate was 80.3%(380/473),similar with that of the control(81.3%,209/257).The incidence of postoperative complications in 3D-CTA simulated group was 37.0%which was significantly lower than that(48.2%) of the control(P<0.01). The intraoperative blood supply for simulated group and the control was(523.4±208.1) mL and (592.0±263.3) mL,respectively,with significant difference between two groups(P<0.01).And the operation time[(314.8±106.3)]min was significantly lower in simulated group than that in the control[(358.4±147.9) min](P<0.01).Conclusions:Application of 3D-CTA imaging technology in risk level assessment before large-scaled meningioma resection could assist in the rational planning of tumor resectin,surgical routes,and is helpful in reducing injuries and complications and enhancing the prognosis of the patients.
