3A review of friction stir welding of steels: Tool, material flow, microstructure, and properties显示文摘Considerable progress has been achieved in friction stir welding(FSW) of steels in every aspect of tool fabrication, microstructure control and properties evaluation in the past two decades. With the development of reliable welding tools and precise control systems, FSW of steels has reached a new level of technical maturity. High-quality, long welds can be produced in many engineering steels. Compared to traditional fusion welding, FSW exhibits unique advantages producing joints with better properties. As a result of active control of the welding temperature and/or cooling rate, FSW has the capability of fabricating steel joints with excellent toughness and strength. For example, unfavorable phase transformations that usually occur during traditional welding can be avoided and favorable phase fractions in advanced steels can be maintained in the weld zone thus avoiding the typical property degradations associated with fusion welding. If phase transformations do occur during FSW of thick steels, optimization of microstructure and properties can be attained by controlling the heat input and post-weld cooling rate.F.C. Liu Y.

4地物热辐射方向性影响主因子的揭示──提高辐射温度方向性观测精度的新途径及数据剖析显示文摘排除影响地物热辐射方向性三因子以外的噪声,即消除热红外传感器随着测 量角度的变化所接收到的组分变化所引起的噪声;消除前后测量的时间差里地表热量 平衡变化所引起的噪声,这是多角度遥感测量中的难题,长期以来一直没有得到解决. 提出利用“热像仪-定面积法”和“双传感器-同步法”进行测定.试验结果表明,以前 的几种方法所观测到的数据离散、无规律,而利用本方法获取的数据,呈现出相当有规 律的方向性分布.从而揭示了影响地物目标热辐射方向性的主要因子和它们各自的影 响程度.张仁华 孙晓敏 李召良 M.P.

5Effect of Combined Chilling and GA_3 Treatment on Bud Abortion in Forced ‘Luoyanghong' Tree Peony(Paeonia suffruticosa Andr.)显示文摘This research investigated the effect of combined chilling and GA_3 treatment on bud abortion of tree peony under greenhouse conditions to determine the dynamics of exogenous hormones and chilling effects on bud abortion. Research of such nature will increase the understanding of the effects of GA_3 and chilling level on flower development thereby, promoting off-season cultivation techniques in tree peonies to increase production that meets market demand. Hormone and sugar levels in the ‘Luoyanghong' tree peony were respectively determined using High-Performance Liquid Chromatography(HPLC) and spectrophotometer. Non-potted chilling with 200 mg·L^(-1) GA_3 treatment reduced bud abortion rate. Flowering rate in non-potted chilling with 200 mg·L^(-1) GA_3 plants was 58%, as against 21% in potted chilling plants with 200 mg·L^(-1) GA_3 treatment. Sugar accumulation in retained or aborted flower buds was conversely related to ABA level. Low ABA and high sugar levels were noted in retained buds whereas the reverse induced bud abortion. ABA level apparently inhibited sucrose and reducing sugar uptake in aborted buds whereas GA_3 enhanced sucrose uptake in retained buds. GA_3 and IAA levels were higher in retained than in aborted buds, which made plants with retained bud more competitive in nutrient uptake(by root)for growth and development. Overall, combined chilling and GA_3 treatment enhanced plant growth and development, particularly bud sprouting, growth and flowering.MORNYA Philip M.P.

7东亚水鼠耳蝠形态描述与分类显示文摘水鼠耳蝠Myotis daubentonii(Chiroptera,Vespertilionidae),广泛分布于欧洲和亚洲,亚种分化众多,在亚洲已报道有M.d.ussuriensis,M.d.loukashkini,M.d.petax和M.d.laniger等,但其分类地位一直受到国内外学者的关注。中国的水鼠耳蝠长期以来被认为属于水鼠耳蝠M.daubentonii亚种。最近有研究认为中国的水鼠耳蝠与欧洲的水鼠耳蝠M.daubentonii不同,并把'petax'提升为种。在中国境内相继采到17只鼠耳蝠标本,根据外形、头骨、牙齿、阴茎骨、线粒体DNA细胞色素b等特征,鉴定为东亚水鼠耳蝠Myotis petax,对中国水鼠耳蝠的种和亚种分类做一讨论。王磊 江廷磊 孙克萍 王应祥 Tiunov,M.P. 冯江 2010动物分类学报2010,35,2:5

14Effect of Alstonia scholaris bark extract on testicular function of Wistar rats显示文摘Aim:To evaluate the antifertility effect of Alstonia scholaris bark extract in male rats.Methods:In male Wistar rats Alstonia scholaris bark extract was given by oral route at a dose of 200mg/day for60days,The fertility and testicular function were assessed by mating tests,sperm motility,sperm concentration,biochemical indices and testicular cell population dynamics.Results:Oral feeding with the extract at a dose of 200mg/day for the period of 60days did not cause body weight loss,while the weights of testes,epididymides,seminal vesicle and ventral prostate were significantly reduced.The production of step-19 spermatids was reduced by 79.6%in treated rats.The popu-lation of preleptotene and pachytene spermatocytes were decrased by61.9%and60.1%,respectively.Spematogo-nia and Sertoli cell population were also affected.The seminiferous tubule and Leydig cell nuclear area were reduced significantly(P<0.01)when compared to the controls..Reduced sperm count and motility yesulted in a total supprs-sion of fertility.A significant fall in the protein and sialic acid content of the testes,epididymides,seminal vesicle and ventral prostate as well as glycogen content of testes were also noticed.The fructose content in the seminal vesicle was lowered whereas the testicular cholesterol was elevated as compared with the controls.The following com-pounds were obtained from the extract with chromatographic separation over Si-gel column;α-amyrin,β-amyrin,lupiol acetate,venenative,rhazine and yohimbine,Conclusion:At the dose level employed,Alstonia scholaris bark extract has a significant antifertility effect in male rast;the primary site of action may be post meiotic germ cells(Step19spermatids).R.
