There is a NE-trending earthquake hazard anomalous zone in the western part of the area of the city ofbeijing proper. A comprehensive study of it has been made. In the study the two-dimensional finite element dy-namic analysis and supersonic seismic model experiments were conducted for the first time. and some prelimi-nary results have been achieved. The beijing depression, a lower order tectonic unit in the beijing downwarp, is just located below theearthquake hazard anomalous zone. Analysis of the experimental results shows that the topography of the bu-ried bedrock is the main factor responsible for the presence of the anomalous zone. Besides. thetwo-dimensional mathematical analysis has more marked advantages in reflecting the lateral inhomogeneity ofthe foundation as compared with the one-dimensional one. and the supersonic seismic model experiments mayreflect the integrated effects of the earthquake sources, path of wave propagation and site geological structurein an all-round way.

目的探讨后壁压缩对切开复位内固定治疗髋臼后壁骨折疗效的影响。方法回顾性分析2017年1月至2020年12月期间首都医科大学附属北京积水潭医院创伤骨科采用切开复位内固定治疗的83例髋臼后壁骨折患者资料。根据后壁压缩与否分为两组:压缩组33例,男26例,女7例;年龄(47.4±11.6)岁;后壁存在压缩。非压缩组50例,男43例,女7例;年龄(41.3±12.0)岁;后壁无压缩。比较两组患者的术后骨折复位质量、末次随访时患髋功能及随访期间并发症发生率等。采用多因素二元logistic回归和年龄亚组分析髋臼后壁压缩对功能结局的影响。结果压缩组患者的年龄、合并其他部位损伤比例及髋臼后壁粉碎比例显著大于非压缩组患者,差异均有统计学意义(P0.05)。所有患者术后获(44.5±13.3)个月随访。非压缩组患者术后骨折解剖复位率(96.0%,48/50)显著高于压缩组患者(57.6%,19/33),末次随访时改良Merle d’’Aubigné & Postel评分优良率(84.0%,42/50)也显著高于压缩组患者(51.5%,17/33),差异均有统计学意义(P0.05)。校正年龄、性别等一般资料后,两组患者髋关节功能比较差异仍有统计学意义(OR=0.23,95%CI:0.06~0.79,P=0.020)。后壁压缩对功能结局的影响在年龄≥50岁患者中差异有统计学意义(P=0.008),而在年龄<50岁患者中差异无统计学意义(P=0.194)。结论在髋臼后壁骨折中,相较于非压缩骨折,压缩骨折更容易导致较差的骨折复位质量,从而影响患者术后髋关节功能的恢复。后壁压缩对功能结局的影响在年龄≥50岁患者中更为显著。

为获得真实可靠的现场实测煤层瓦斯压力,实现煤层突出灾害等级科学评价和精准防治,通过理论分析、数值模拟和现场验证相结合的方法,以双重孔隙介质为基础,根据煤层瓦斯流动模型和瓦斯压力恢复曲线,分析煤层瓦斯压力测定的时空分布及准确性,并以桃园煤矿Ⅱ1采区10煤层为例,开展工程验证。研究结果表明:当基质瓦斯压力与裂隙瓦斯压力处于动态平衡时,所测得的煤层瓦斯压力最为准确;所构建的用于COMSOL解算的煤层测压瓦斯流动方程,可实现瓦斯压力时空分布的准确模拟;当煤层实测瓦斯压力恢复曲线与模拟分布特征一致且处于工程预测值范围内,可以判定结果为真实值;现场工程验证了实测瓦斯压力恢复曲线与模拟结果一致,测压结果准确。

Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department *** syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, beijing Pediatric Society, beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.

大型固定式跨海通道建设投资巨大、建设周期长、对国民经济和周边环境影响大,世界各国对这类工程的立项、建设历来都采取非常慎重的态度。大型跨海工程在建设过程中不可避免会出现很多问题,如项目决策、投融资方式、前期论证、技术方案及运营维护方案等。通过对建设比较成功的日本和欧洲跨海通道体系调研分析,得出结论:项目决策应从国家整体发展的角度出发;建设资金筹集应合理选择投融资模式;项目研究应高度重视前期勘察论证;因地制宜确定技术方案;运营维护方案应科学、经济、有效。
