CrWMn钢的恒温超塑性

洛阳工学院学报 1985年第2期 41-47页

作者：董企铭杨蕴林康布熙席聚奎

CrWMn钢经循环加热淬火超细化处理后,在710～730℃,拉伸夹头速率为0.2-0.8mm/min变形时均可获得极佳的超塑性,其最大延伸率达816%,而流变应力仅为2.75kgf/mm~2.利用lgσ-lgε曲线斜率法测得其应变速率敏感性指数-m值为0.4左右.

A total of 21 compounds were isolated from the seeds of Capparis masaikai and identified as oxazolidine-2-thione(1), succinimide(2), catechol(3), octathiocane(4), monoethanolamine(5), 3-hydroxypropanenitrile(6), L-arabinose(7), 1,2,3-propanetriol(8), drummondol(9), spionoside B(10), adenosine(11), corchoionoside C(12), coniferin(13), syringin(14), cis-syringin(15), dihydrosyringin(16), indole-3-carboxylic acid(17), β-D-glucopyranosyl indole-3-carboxylic acid(18), 6-hydroxyindole-3-carboxylic acid β-D-glucopyranosyl ester(19), linoleis monoglyceride(20), and triolein(21). Their structures were identified based on physicochemical property and spectroscopic analysis, including MS, NMR, and single-crystal X-ray crystallographic data. Compounds 2–10 and 12–21 were isolated from C. masaikai for the first time.

Following our previous work,we studied the partial eruption of a large-scale horse-shoe-like filament that had beenobserved in a decaying active region on the solar disk for more than 4.5 *** filament became active after itwas broken into two pieces,P1 and P2 seen in Hα,by magnetic reconnection between the magnetic field around itand that of a newly emerging active region nearby.P1 eventually erupted 13 hr after the breaking and escaped fromthe Sun,developing to a fast coronal mass ejection,and P2 *** the mass in P1 falling down to P2 in theeruption suggests that the global magnetic fields over P1 and P2 were still connected to each other prior to *** reconnection process breaking the filament occurred outside the filament,and P1 and P2 were locatedalmost at the same altitude,so the fashion of the filament partial eruption studied here differs from that of the“double-decker model”and that of reconnection inside the *** the decay indices of thebackground fields above P1 and P2,n_(1)and n_(2),showed that the altitude where n_(1)exceeds the critical value of n_(c)=1.5 for the loss of equilibrium or the torus instability is lower than that where n_(2)>nc,and that n_(1)>n_(2) alwaysholds at all *** this fact with that the eruption occurred 13 hr after filament was broken byreconnection,we conclude that the eruption of P1 was triggered by the loss of equilibrium or the torus instability inthe configuration,and magnetic reconnection breaking the filament helped weaken the confinement of thebackground field on P1,allowing P1 to *** features of the eruption and the corresponding physicalscenario were also discussed.

中国的紫水鸡为罕见种,数量不断减少。2011年12月至2012年5月期间,在滇池湿地4次发现紫水鸡云南亚种实体,并详细描述了其活动特征与生境特征。紫水鸡在滇池湿地的活动局限在1 km^2范围内,白昼完全暴露的时间不超过30 min,常与黑水鸡同时出现,但比较警觉。紫水鸡偏爱的生境是由高草丛、低草丛、平静的浅水池塘交错组合的湿地景观,且要求人为活动稀少的安静的栖息地。参照中国关于紫水鸡的研究材料,认为在过去的20多年里,紫水鸡云南变种从滇南、滇西南越过分隔云南东部和西部的云岭-哀牢山山脉,到达滇西北鹤庆一带,及少数个体到达了位于滇中腹地的滇池湿地。讨论了强化保护紫水鸡的必要性,建议尽快将紫水鸡纳入国家或者地方的相关法律法规,给予重点保护。
