Acer velutinum Bo.ss is a valuable tree species native to.Iran, and its seeds po.sess physio.o.ical do.mancy that hampers seedling pro.uctio. in the nursery fo. large-scale refo.estatio. effo.ts. The aim o. this study was to.determine the o.timal do.mancy breaking treatments fo. A. velutinum seeds. We co.ducted a facto.ial experiment invo.ving six seed lo.s co.lected alo.g an elevatio. gradient fro. 300 to.1800 m at 300 m interval and fo.r co.d-mo.st stratificatio. perio.s （0, 4, 8 and 16 weeks） at 4℃ and 70% relative humidity. The result sho.s that the germinatio. o. co.d-mo.st stratified seeds was significantly （p 〈 0.0001） higher than the co.tro. fo. all seed lo.s. The highest germinatio. capacity was reco.ded after 16 weeks o. co.d-mo.st stratificatio. fo. all seed lo.s （68% 88% depending o. the seed lo.） except tho.e co.lected fro. mid altitude sites （600 and 900 m） that germinated equally well （≥ 75%） after 4and 8-week o. clo.-mo.st stratificatio. co.pared to.the o.her seed lo.s. The mean germinatio. time was significantly sho.ter （12 to.19 days, depending o. the seed lo.） fo. seeds stratified fo. 16 weeks than fo. untreated seeds. It can be co.cluded that：（1） co.d-mo.st stratificatio. fo. 16 weeks is the best pre-so.ing treatment fo. breaking do.mancy in A. velutinum seeds; and （2） seeds sho.ld be co.lected fro. mid altitude sites （600 and 900 m） to.get mo.e than 80% germinatio. within 15 days, and these seed lo.s even required sho.ter co.d-mo.st stratificatio. perio.（eight weeks） than o.her seed lo.s.

研究射流速度、石英砂浓度和撞击角度对冲蚀和冲蚀-腐蚀后铝黄铜表面粗糙度的影响。冲蚀和冲蚀-腐蚀实验在射流冲击机中进行。采用二维和三维轮廓曲线仪以及扫描电子显微镜表征被侵蚀样品表面。结果表明,在9、6和3 m/s射流速度下,分别增加石英砂浓度至1、5和10 g/L,冲蚀-腐蚀试样表面粗糙度增加;但是,进一步增加石英砂浓度,由于试样表面的加工硬化、反弹或覆盖效应以及高频冲击作用,试样表面粗糙度降低。随着射流速度的增加,试样表面粗糙度增加。研究结果还表明,当射流速度为3和6 m/s时,试样表面粗糙度随撞击角度的变化并不明显;而在较高的射流速度9 m/s时,倾斜撞击造成腐蚀表面形成波痕,因此,具有比正面撞击试样更高的表面粗糙度。

The astro.hysical S-facto. o. the 4He＋12C radiative capture is calculated in the po.ential mo.el at the energy range 0.1-2.0 MeV. Radiative capture 12C（α,γ） 16o.is extremely relevant fo. the fate o. massive stars and determines if the remnant o. a superno.a explo.io. beco.es a black ho.e o. a neutro. star. Because this reactio. o.curs at lo. energies, the experimental measurements are very difficult and perhaps impo.sible. In this paper, radiative capture o. the 12C（α,γ） 16o.reactio. at very lo. energies is taken as a case study. In co.pariso. with o.her theo.etical metho.s and available experimental data, go.d agreement is achieved fo. the astro.hysical S-facto. o. this pro.ess.

The relatio.ship between spatial patterns o. macro.entho. co.munity characteristics and enviro.mental co.ditio.s（salinity, temperature, disso.ved o.ygen, o.ganic matter co.tent, sand, silt and clay） was investigated thro.gho.t the Go.gan Bay in June 2010. Principal co.po.ents analysis（PCA） based o. enviro.mental data separated eastern and western statio.s. The maximum（4 500 ind./m2） and minimum（411 ind./m2） densities were o.served at Stas 1 and 6, respectively. Po.ychaeta was the majo. gro.p and Streblo.pio.gyno.ranchiata was do.inant species in the bay. Acco.ding to.Distance Based Linear Mo.els results, macro.aunal to.al density was co.related with silt percentage and salinity and these two.facto.s explaining 64% o. the variability while macro.aunal co.munity structure just co.related with salinity（22% to.al variatio.）. In general, western part o. the bay sho.ed the highest number o. species and bio.iversity while, the highest density was fo.nd at Sta. 1 and in the middle part o. the bay. Furthermo.e, relatio.ship between diversity indices and macro.enthic species with measured facto.s is also.discussed. o.r results co.firm the effect o. salinity as an impo.tant facto. o. distributio. o. macro.enthic fauna in so.th Caspian brackish waters.
