A record-breaking extreme Meiyu rainfall occurred along the Yangtze River valley(YRV)in 2020 since 1961,persisting from 11 June to 31 July with the largest amount and the highest *** the aspect of water vapor,the causes of its formation are revealed in this *** 2020 Meiyu rainfall amount is directly attributed to the greatly enhanced vertically integrated water vapor transport(IVT)convergence,which is in turn primarily determined by the mean circulation dynamic(MCD)contribution associated with anomalous East Asian summer monsoon(EASM)and the thermodynamic component(TH)contribution due to water vapor *** MCD contribution is mainly responsible for the extreme Meiyu rainfall amount and abundant water vapor convergence in the YRV,whereas the TH contribution tends to shift Meiyu rain belt northward to the Yangtze-Huaihe River valley,extending the Meiyu rainfall coverage ***,the excessive moist static energy(MSE)associated with the largest water vapor anomaly could substantially increase the atmospheric instability,favoring the extreme 2020 Meiyu rainfall *** terms of the tremendous IVT to the YRV from both the South China Sea and Bay of Bengal during the 2020 Meiyu period,the low-level anticyclone anomalies over the western North Pacific(WNP)and Bay of Bengal provide appropriate atmospheric circulation conditions,and they are generated by the super suppressed WNP convective activities as a Matsuno-Gill type response,which are further attributed to the combined warm SST anomalies in both the tropical western Indian Ocean(TWIO)and tropical Atlantic Ocean(TAO)eventually.

Neural Regeneration Research 2012年第20期7卷 1556-1562页

作者： Shijing Deng Mengmeng Wang Fengju Zhang xuguang sun Wenbo Hou Ning Guo Beijing Institute of Ophthalmology Beijing Tongren Eye Center Beijing Tongren Hospital Capital Medical University Beijing 100005 China Beijing Tongren Eye Center Beijing Tongren Hospital Capital Medical University Beijing 100005 China

A total of 26 myopic patients （52 eyes） underwent laser in situ keratomileusis. In vivo confocal microscopy revealed that most of the regenerated corneal subbasal nerve fibers in the comeal flap originated from the stump of corneal subbasal nerve fibers outside the ablation zone and extended towards the center of the cornea in all patients. Meanwhile, new fibers were also found to directly regenerate from deep in the stroma in some cases. Approximately 94% of regenerated corneal subbasal nerve fibers （73/78 eyes） regrew vertically into the peripheral central 6-mm circle area 1 month after surgery, 78% （28/36 eyes） grew into the central 3 6 mm area at 2 months, and 23% into the central 3-mm circle area at 3 months. In addition, there was no significant difference in corneal subbasal nerve fiber regenerative capacity between the basic fibroblast growth factor group and the 20% （vN） deproteinized extract of calf blood group. The majority of corneal subbasal nerve fiber regeneration occurred from the stump of corneal subbasal nerve fibers outside the corneal flap and the remaining growth occurred deep within the stroma.

目的探讨神经营养性角膜炎(NK)的临床特征及诊疗特点。方法回顾性系列病例研究。收集2013年5月至2016年7月间在北京市同仁医院眼科门诊临床诊断为NK的患者46例(48只眼),其中男性26例(26只眼),女性20例(22只眼),年龄(51±18)岁。对患者一般情况、病因、眼部临床症状和体征、病程分期及疗效进行分析,总结NK患者的临床特征。25例患者(26只眼)应用Cochet-Bonnet角膜知觉检测仪测量角膜知觉,分析角膜知觉与临床分期的相关性。对不同程度NK的患者分布特征进行χ2检验。对角膜神经灵敏度和疾病临床分期行Spearman相关性分析。结果44例NK患者为单眼发病(95.65%),2例(4.35%)为双眼发病。18~29岁的患者4只眼,占8.33%;30~59岁的患者23只眼,占47.92%;≥60岁的患者21只眼,占43.75%。NK患者中,临床分期为Ⅰ期8只眼(16.67%);Ⅱ期21只眼(43.75%);Ⅲ期19只眼(39.58%)。3个年龄段患者各临床分期情况比较,差异无统计学意义(χ2=2.452,P=0.658)。NK最常见的病因为病毒感染17只眼(35.42%)、神经外科手术并发症11只眼(22.92%)和糖尿病10只眼(20.83%)。26只眼角膜知觉值在0~3 cm范围内,角膜知觉与临床分期无明显相关性(r2=0.284,P=0.753)。患者平均随访7个月,34只眼(70.83%)采用保守治疗,8只眼(16.67%)最终手术治疗,6例(6只眼)失访。结论NK可发生于各年龄人群,主要为中、老年人,且临床表现多样,如不及时诊治,常会引起角膜溃疡。角膜知觉与病变临床分期无明显相关性。早期诊断和针对性分期治疗对保护患者视功能十分重要。

为研究穿甲弹斜侵彻钛合金靶板的极限跳飞角度及相关影响因素。开展了7.62 mm穿甲燃烧弹的弹道冲击试验,获取了弹体斜侵彻不同厚度、不同倾斜角度钛合金靶体的极限跳飞角度;同时利用有限元软件LS-DYNA对穿甲弹斜侵彻钛合金靶体进行数值模拟仿真,并与试验数据对比验证模型的有效性;随后讨论了靶板倾角与靶体厚度等因素对弹道性能的影响规律。结果表明:靶板倾角的增大有效降低了穿甲弹的穿甲能力,弹体贯穿后的剩余速度及姿态变化角随靶板倾角的增加而分别呈现非线性下降与上升的趋势;钛合金靶板的极限跳飞角度对靶板厚度敏感,极限跳飞角度随靶板厚度的增加而非线性下降。
