Acta Oceanologica Sinica 2015年第9期34卷 35-42页

The activities of internal solitary waves （ISWs） over the continental shelf of the northern South China Sea （SCS） are of high complexity. In this study, we investigated the spatial-temporal characteristics of the shoaling ISWs over the northern SCS continental shelf using the satellite images and the results of numerical simulation. The examination of the ISW signals in the satellite optical images revealed the existence of three types of iSWs in the region north to the Dongsha Island, namely, mode-1 depression ISW, mode-1 elevation ISW, and mode-2 convex ISW. The geographical distributions of these ISWs were derived from the satellite images. Numerical results exhibited the process of polarity conversion of ISWs, by which mode-1 elevation waves were transformed from the shoaling mode-1 depression waves. The mode-2 convex ISWs generally followed the mode-1 depression ISWs. The numerical results suggested that the interaction of the mode-1 depression ISWs with the up-slope topography locally generated mode-2 ISWs, and such waves of high vertical mode dissipated rapidly during the inshore propagation.

Photons with variable energy, high coherency, and switchable polarization provide an ideal tool-kits for exploring the cutting-edge scientific questions in the condensed matter physics and material sciences. Over decades, extensive researches in the sample fabrication and excitation have employed the photon as one of the important means to synthesize and explore the low-dimensional quantum materials. In this review, we firstly summarize the recent progresses of the state-of-the-art thin-film deposition methods using excimer pulsed laser, by which syntactic oxides with atomic-unit-cell-thick layers and extremely high crystalline quality can be programmatically fabricated. We demonstrate that the artificially engineered oxide quantum heterostructures exhibit the unexpected physical properties which are absent in their parent forms. Secondly, we highlight the recent work on probing the symmetry breaking at the surface/interface/interior and weak couplings among nanoscale ferroelectric domains using optical second harmonic generation. We clarify the current challenges in the insitu characterizations under the external fields and large-scale imaging using optical second harmonic generation. The improvements in the sample quality and the non-contact detection technique further promote the understanding of the mechanism of the novel properties emerged at the interface and inspire the potential applications, such as the ferroelectric resistive memory and ultrahigh energy storage capacitors.

为研究秦川牛TNFSF11基因多态性及其与秦川牛体尺性状的相关性,以399头同等饲养条件下的18～24月龄健康秦川母牛为研究对象,采用PCR-RFLP技术结合DNA测序技术检测TNFSF11基因的SNPs位点,并将其与秦川牛体尺性状进行关联分析。结果表明,DNA测序发现在TNFSF11基因第3内含子即34 080bp处(C331区域)和第3内含子34 096bp处(C332区域)分别发生C→T突变和T→C突变;PCR-RFLP分析发现,秦川牛TNFSF11基因C331区域经创造酶切位点后可以被限制性内切酶HincⅡ特异切割为有GG、GH和HH 3种基因型,C332区域可以被内切酶BseLⅠ特异切割为MM、MN和NN 3种基因型;与测序结果比对显示,秦川牛TNFSF11基因C331、C332各酶切基因型与测序结果显示相一致。卡方检验显示,C331位点在所检测牛群中处于Hardy-Weinberg平衡状态(P>0.05),而C332位点则处于Hardy-Weinberg极度不平衡状态(P<0.01);且C331处GH基因型为优势基因型,G等位基因为优势等位基因,处于中度多态状态;C332处基因型MM为优势基因型,M等位基因为优势基因,处于中度多态状态;关联分析表明,C331位点不同基因型个体间在腰高、腰角宽和胸围方面差异显著(P<0.05),C332位点在体斜长和腰高方面差异显著(P<0.05)。经连锁不平衡检测发现,两位点存在一定的连锁特性(r2=0.213),将两突变位点进行单倍型分析可知,HHMM基因型各性状均显著高于其他基因型组合,且多标记位点的组合效应值高于单标记位点。说明TNFSF11基因对秦川牛体尺性状有显著的影响,可以作为秦川肉牛新品系培育早期选择的候选基因,其中组合HHMM可能是影响秦川牛体尺胴体性状的最佳基因型组合,在选育中应加大其选择力度。

为研究不同水平糖蜜和复合菌酶制剂对鲜食玉米秸秆青贮过程中pH和主要微生物数量变化规律的影响,采用完全随机分组设计,共设置5个处理组:对照组(CK)、A组(2%糖蜜)、B组(复合菌酶制剂)、C组(2%糖蜜+复合菌酶制剂)、D组(4%糖蜜+复合菌酶制剂),抽真空袋装青贮,每组3个重复,分别在发酵的第0、15、30、45、60、90天取样,对青贮饲料pH和乳酸菌、好氧性细菌、酵母菌、霉菌进行测定。研究结果显示:添加不同水平糖蜜和复合菌酶制剂发酵鲜食玉米秸秆过程中,pH和微生物菌落均不同程度发生了变化,各处理组pH、乳酸菌数量均显著高于对照组(P<0.05),好氧性细菌、酵母菌数量均显著低于对照组(P<0.05)。试验表明单独添加糖蜜、复合菌酶制剂或是糖蜜与复合菌酶制剂组合添加均可以降低青贮的pH,促进乳酸的发酵,抑制有害菌的生长,从而改善秸秆的发酵品质。在本试验条件下,添加2%糖蜜+复合菌酶制剂效果最好。
