He jishu针对大型加速器定时系统中各节点因光纤长度差异引起的延时问题，提出了一种基于事件定时系统的深度优先多节点自动延时补偿算法，旨在解决因光纤长度差异导致的时间同步问题与长距离光纤传输带来的稳定性问题，并通过测量不同设备的触发信号到达时间，根据算法进行延时调整，采用125 MHz事件时钟，实现8 ns时间精度的延时补偿。在涉及6 m和30 m光纤长度的测试中，延时补偿成功实现了信号输出对齐，对齐精度约为5.5 ns，证明了该算法在保持不同光纤长度同步方面的有效性，该算法提高了事件定时系统的时间同步精度和稳定性 ...

Journal of Curriculum Studies本研究目的在於考驗主動／被動拖延者在依賴型人格及社會閒散現象之差異，以及控制在團體課業分派下，兩者是否因高／低任務可視性而增加社會閒散現象。研究結果為：一、主動拖延者及被動拖延者之兩組模型關係相似；二、主動拖延者比被動拖延者具有較高之壓力偏好、期限因應能力及意圖拖延，較低的依賴型人格，但與被動拖延者具有相似程度之任務反感及失敗恐懼；三、對被動拖延者而言，低任務可視性組會比高任務可視性組產生較高之社會閒散現象。對主動拖延者而言，高任務可視性組則會比低任務可視性組產生較高之社會閒散現象。 The main

A case of infravesical obstruction caused by prostatic stones as diagnosed by transrectal ultrasonography at voiding [PDF]
, 2001 症例は69歳男で, 排尿困難を主訴とした.尿流量検査で苒延性排尿障害を認め, 経直腸的超音波断層法(TRUS)では前立腺肥大は認めず, 前立腺結石症と診断した.逆行性尿道造影では明らかな尿道狭窄は認めず, 確定診断のためvoiding TRUSを施行した.膀胱頸部の堤防状隆起もなく, 開大も良好であったが, 精阜部の上下に前立腺結石を認め, その部分での動きが悪く, 開大不良と判定した.手術所見で尿道狭窄はなく, 前立腺両側葉による圧排もなかった ...

Jianzhu Gangjiegou Jinzhan设计制作了4个H型钢梁试件，通过拟静力试验得到不同腹板高厚比以及钢种组合下钢梁的破坏形态、滞回曲线、骨架曲线以及延性等，从而评价试件的滞回性能。随后利用有限元软件ABAQUS进行模拟验证，通过参数分析进一步补充不同腹板高厚比和钢种组合对钢梁滞回性能的影响。结果表明：随着腹板高厚比的减小，钢梁的延性和耗能能力均有所提高，且增大腹板厚度对钢梁延性的提高程度大于极限承载力的提高程度；相比同钢种钢梁，多钢种钢梁极限承载力提高了17.4%，延性降低5.6%。随着多钢种钢梁翼缘强度等级的增大 ...
