| 1 | Antibacterial Behavior of a Cu-bearing Type 200 Stainless Steel显示文摘A preliminary study was made on the antibacterial behavior of a newly designed Cu-bearing type 200 stainless steel by different methods including Vickers hardness measurement, electrochemical test and antibacterial test. The results showed that Cu-rich precipitations caused by the saturated Cu in the steel matrix was not only a crucial factor for its excellent antibacterial capability, but also for its equivalent corrosion resistance as good as the commercial type 200 stainless steel. | Li Nan Jinglong Cheng Ke Yang | 2012 | Journal of Materials Science & Technology2012，28，11： | 12 |
| 2 | Statistical characteristics of the surface ducts over the South China Sea from GPS radiosonde data显示文摘Based on the global position system(GPS) radiosonde data near the sea surface, the surface duct characteristics over the South China Sea(SCS) were statistically analyzed. The annual surface duct occurrence over the SCS was about 64%. Of the observed surface ducts, duct heights mainly distributed between 18 and 42 m, with M slopes in the range of –0.3 to –0.2 M units/m. Those ducts accounted for about 80% of the ducting cases. For the total profiles, the duct occurrences in a day changed slowly and were more than 60% in all times. The surface ducts formed more easily in the daytime than in the nighttime and most of the duct height were at bellow about 32 m.Additionally, The seasonal variation of the SCS ducts appeared to be evident, except that the mean duct thickness was almost constant, about 33 m for all seasons. The highest occurrence was about 71% in the autumn, followed by in the summer, spring and winter. In spring, their top-height existed more often at a height of more than 48 m.Their mean duct strength became stronger trend from spring to winter, with the M-slope in the range between–0.26 and –0.18 M units/m. Those results agreed well with other studies, provided considering the data resolution.The statistical analysis was reliable and gave the duct estimation for the SCS. Such duct climatology not only has important implications for communication systems and the reliability of the radar observation, but also can provide useful information to improve the accuracy of the meteorological radar measurements. | CHENG Yinhe ZHOU Shengqi WANG Dongxiao LU Yuanzheng YAO Jinglong | 2015 | Acta Oceanologica Sinica2015，34，11： | 2 |
| 3 | Genetic segregation analysis of unsaturated fatty acids content in the filial generations of high-linolenic-acid rapeseed(Brassica napus)显示文摘Alpha linolenic acid(ALA)is an essential polyunsaturated fatty acids that can improve human health.Rapeseed is the second largest oil crop in the world but the ALA content in its seed fatty acids is only about 10%.Two rapeseed germplasms YH25005 and R8Q10 with high content(up to 21%)ALA were developed by intervarietal crossing.They were used as the maternal parent(P_(1))when crossed with a low ALA parent SW(P2)to produce the seeds of the F1 hybrid,F2,and backcrosses to P1(BCP1)and P2(BCP2).A multigeneration joint segregation analysis was conducted to determine major gene t polygene effects of the content of three major unsaturated fatty acids including oleic(OA),linoleic(LA)and ALA.The results showed that,although some genes favorable to ALA accumulation were not allelic in R8Q10 and YH25005,all the inheritances of OA,LA and ALA in YH25005×SW and R8Q10×SW followed a genetic model of‘two pairs of additive major genes t additive-dominant polygenes’.It is suggested that the contents of OA,LA and ALA are closely related and the major genes in the parent SW containing loss-of-function mutations in FAD2 and FAD3 loci had strong effect to reduce ALA and elevate OA.However,total genetic effect of the polygenes was greater than that of the two major genes,especial on ALA content.It indicated that it is necessary to employ a larger F2 population to find the plant that accumulate enough minor-effect polygenes for high ALA content.The results are useful for high ALA rapeseed breeding and future work of gene mapping. | Xiaohan Zhang Jinglong Lian Chunyan Dai Xiaoli Wang Mingzheng Zhang Xing Su Yaohua Cheng Chengyu Yu | 2021 | Oil Crop Science2021，6，4： | 0 |
