引言一般来说,十字板剪切试验是用四块叶片进行的,叶片高度是其直径的两倍。作用在叶片上的力矩使叶片大约以6度/分钟的速度转动,直到发生破坏。许多研究者已进行了十字板剪切试验研究（1,2,4,5,8,10）*。这些研究指出:十字板剪切强度可能受十字板几何形状的影响（1,8）,而且高塑性粘土的十字板剪切强度有随着剪切速度的加快而增大的趋势（10）。本文所介绍的是室内采用不同剪切速度进行一系列十字板剪切试验的结果。在低塑

从1994年北岭地震中可看到,栓焊节点的抗震性能较差。因此,常用于工业建筑和高层建筑中的抗弯框架多采用端板连接和T型螺栓连接。采用有限元方法,通过改变螺栓的纵横布置对比了14个试件的滞回性能。结果表明:假定两者总的耗能能力相同,则T型螺栓连接的抗弯能力和初始转动刚度均比基于AISC规范设计的端板螺栓连接高。在往复荷载作用下,螺栓布置的改变对T型螺栓连接破坏模式的影响要大于端板连接,端板连接更适用于具有初始几何缺陷的结构。

Background and Objectives: Following the initial management, some patients with differentiated thyroid cancer (DTC) develop a state of high thyroglobulin (Tg) and Negative Iodine Scintigraphy. The predisposing factors and outcome of this condition are unclear. In this study, our objectives were to analyze the characteristics of patients with high Tg level and negative Iodine scintigraphy and to determine the predictive factors for development of high Tg and negative scintigraphy. Patients and Methods: Retrospective study of 34 patients undergoing treatment for DTC, followed in the Nuclear Medicine department of the University Hospital—Sahloul Sousse between 1990 and 2006 and having a high Tg and negative Iodine scintigraphy. Fourteen patients had Tg between 2 and 10 ng/ml, 16 had Tg between 11 and 100 ng/ml and 4 patients had Tg more than 100 ng/ml. Results: There were 25 women and 9 men. The mean age was 51.65 years. In 94.1% of cases, the tumor was papillary carcinoma. Follicular tumors accounted for only 5.9%. The mean nodule size was3.26 cm. Capsular invasion was seen in 47.1% cases. The locoregional invasion was found in 35.3%. The lymph node extension was found in 84.8% of patients having lymph node surgery. Lymph node involvement was observed in 92.8% of patients with papillary cancer but it was found in 7.2% of patients with follicular cancers. Lymph node invasion was unilateral in 28.6% (N1a) and bilateral, contralateral or mediastinal in 71.4% (N1b). Initial level of Tg was as follows: 7 patients had Tg between 2 and 10 ng/ml, 14 patients had Tg between 11 and 100 ng/ml and 12 had Tg more than 100 ng/ml. The mean number of radioactive Iodine cure was 11.08 for patients with Tg more than 100 ng/ml with a significant difference (P = 0.001). Conclusion: Among epidemiological, pathological and clinical characteristics, lymph node invasion is the most frequent parameter found in patients with a DTC with high Tg level and negative Iodine scintigraphy.

Advances in Computed Tomography 2012年第2期1卷 11-16页

Background: Cardiac output can be estimated during retrospectively gated CT coronary angiography by anatomically determining left ventricular volumes;prospective triggering to minimize radiation precludes this methodology. We propose an alternative method for cardiac output estimation based on preclinical models suggesting that cardiac output may be inversely related to contrast washout from the aortic root during timing bolus scanning, as measured by peak aortic root contrast attenuation. Methods: 34 patients had CT coronary angiography timing bolus performed with 20 ml iodixanol at 5.5 ml/s followed by 20 ml normal saline at 5.5 ml/s through an 18-Ga antecubital catheter. Peak aortic root contrast attenuation was correlated to cardiac output calculated by echocardiography using heart rate stroke volume from biplane Simpson’s ***: Mean age was 58 ± 13 years;body surface area, 2.0 ± 0.5 m2. 53% were women. Stroke volume, cardiac output and cardiac index were 67 ± 19 ml, 4.5 ± 1.6 L/min, and 2.2 ± 0.7 L/min/m2, respectively. Peak aortic root contrast attenuation was 207 ± 46 HU and correlated to cardiac output and cardiac index with r = –0.64, p Conclusion: This novel method for cardiac output estimation by CTCA appears feasible. The CT physiologic parameters using the timing test-bolus data moderately correlated with echocardiographic assessment of cardiac output. The calculation of cardiac output adds important hemodynamic data to anatomic information provided by CTCA, and further development of this method may preserve assessment of left ventricular performance in prospective triggering.
