金属加工温度梯度及其不等温韧性

钢铁 1997年第9期32卷 33-36页

作者：陈伟昌 H.S.ferguson 韦东滨贺毓辛北京科技大学

引入不等温韧性的概念，并定义其为不同温度下的断面收缩率。研究表明，材料的不等温韧性与存在于各种工业加工过程中的温度梯度有关。温度梯度越大，不等温韧性越低。

上次在法国南部期间、我习惯在一条安静的路上骑自行车。在转角处我会经过一座不大的老房子,院子里有一位胖胖的、脸色红润的妇人,她总是穿着花围裙和绒毛拖鞋。不知为何,她身上有一些东西引起了我的兴趣,她让我有伸出手的冲动。... 详细信息

上次在法国南部期间、我习惯在一条安静的路上骑自行车。在转角处我会经过一座不大的老房子,院子里有一位胖胖的、脸色红润的妇人,她总是穿着花围裙和绒毛拖鞋。不知为何,她身上有一些东西引起了我的兴趣,她让我有伸出手的冲动。当我经过的时候,我向她挥手。她一定认为我只是一个无聊的旅行者,因为她没有向我挥手。

洋地黄与心衰时神经激素的异常及其治疗的联系

作者： G.ferguson Maunsell Geotechnical Services Ltd. Maunsell Aecom Group

The twin 15.43 diameter slurry TBMs provided for boring the two 7.5 kilometre road tunnels,for the underground section of the river crossing link from Pudong,Shanghai to Chongming Island,were designed to deal with very soft ground conditions including clay,silts and sand under high hydrostatic pressures and relatively low *** paper will concentrate on the TBM's performance in dealing with the following:(1) launching the TBMs from the Launch Shaft;(2) the initial driving with shallow cover;(3) the steering of the TBM and guidance system;(4) the grouting system during the TBM advance;(5) the ring building operation and the ring type;(6) the separation plant for re-cycling the slurry and maintaining its required *** paper will also include a short description about the development of the slurry TBM to its present set up and describe the advantages of the TBM's grouting *** type of rings used on this project is compared to other types on other projects.

国外医学（心血管疾病分册） 1993年第1期20卷 16-18页

作者： ferguson DW 王健

心衰的主要病理生理特征是神经激素的激活,主要是交感神经系统兴奋。经实验研究证实:临床心衰的特征是交感神经对心肌的作用增强,其程度与心肌功能相平行,当给心衰患者应用洋地黄时,除有正性肌力作用外,还有很强的自主神经系统作用。

回顾了近年来发表的碳酸盐生油岩方面的文献,尤其是那些详细论述了生油岩岩性和其沉积环境以及生油岩中的有机质等方面的文献。业已证明,适用于其他生油岩的沉积和环境判据,对于碳酸盐同样是有效的。有证据表明,这些生油岩中的粘土矿物的催化作用是微不足道的。所强调的另一特征是“同生源”。文献中列出的证据要求人们重视两种“同生源”模型:1)油气完全是在原地形成并储集起来的;2)油气形成后经过运移并在碳酸盐杂岩体中储集起来。模拟实验得到的结果,无论是已发表的还是未发表的,都将说明上述结论的正确性。

本文回顾了研究碳酸盐源岩的近期文献。这些文献中,特别重要的是提到了该碳酸盐岩的岩石学、沉积环境以及与有机质相关的详细内容,证明了用于其它源岩的沉积和环境标准对于碳酸盐岩来说同样走有充分根据的。给出的资料确认了粘土矿物在碳酸盐岩中的催化作用是最小的。另一个要强调的特征是自生烃。文中回顾了自生烃的两种形式认识上的说法,即:油或气确实走原地的并且在发现的地方生成,或者它能在碳酸盐岩的块体内运移。依据公开的或尚未公开的试验工作所提供的资料提出了文中的一些主要结论。
