2012-2013年从越南3个省调查采集到病死松树样本52份。将病死松木中所获线虫分离、提纯、培养后,通过显微测量及Deman公式计算所获线虫的V、a、b等相关部位数值,并对其形态特征进行描述。初步结果表明在样本中仅分离到1种伞滑刃属线虫,即泰国伞滑刃线虫(Bursaphelenchus thailandae Brassch&Brassch-Bidasak,2002)。通过对其ITS序列的研究,以伞滑刃属线虫ITS区通用引物P1:5’-CGTAACAAGGTAGCTGTAG-3’,P2:5’-TTTCACTCGCCGTTACTAAGG-3’,分别对分离得到的线虫进行PCR扩增,得到880bp左右的扩增片段。通过克隆并测序,然后进行测序分析及比对,结果鉴定出线虫种群为泰国伞滑刃线虫(***),这也与前部分形态鉴定相符合。这是越南关于松树上伞滑刃属线虫种类研究的首次报道。

It is know that Multi-walled Carbon Nano Tubes (MWCNTs) are an excellent conduction nanomaterial while Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) is a conductive and transparent polymer. In this paper, we mix MWCNTs with PEDOT-PSS to create a new type of nanocomposite thin film which has both excellent conduction and transparency of each composition materials for applications in electronics and optoelectronics. The nanocomposite is synthesized by modifying MWCNTs in an acid solution then mix with PEDOT-PSS. The field emission scanning electron microscopy (FESEM) images of the fabricated thin film with 0.3 Wt% of MWCNTs show that the diameter and length of the MWCNTs are ca.10-30 nm and 300-500 nm, respectively. Electrical and optical properties of thin film are also investigated: the sheet resistance reaches the minimum value of 36.5 ?/sq with the transparency of ca.76% at the wave length of 600 nm. Furthermore, I-V characteristics of organic light emission diodes (OLEDs) made by the synthesized nanocomposite thin films are analyzed. The ITO/PEDOT-PSS: CNTs/PVK: MEH-PPV/Al multilayer OLED exhibits well improving performance with the work function of 0.8 V corresponding with the current of 0.4 mA while the ITO/PVK: MEH-PPV/Al simple OLED has the work function of 3 V and the current of only 0.01 mA.

为确定造成越南松林的枯死是否为松材线虫所为,对越南南部的林同省、中部的承天-顺化省、北部的广宁省的思茅松(Pinus kesiyaRoyle)、马尾松(***.)和南亚松(*** et de Vries)松树枯死现象及症状特点进行了调查,分别从52株枯死、濒死、健康松树木质部中抽取木质部样品,进行线虫分离,根据形态学特点确定这些松树体内寄生线虫的种类。调查发现松树在枯死过程中,树冠部分针叶失去光泽,逐渐褪绿变黄,进而褐红干枯,最后整个树冠变为褐色或红褐色,全株枯死,针叶下垂且当年不落;随着病程的发展,松脂分泌逐渐减少,直至停止;树干上有天牛产卵刻槽,死亡的松树上有天牛的羽化孔。在抽取的松树样品中分离鉴定到了泰国伞滑刃线虫(Bursaphelenchus thailandae)、悬臂伞滑刃线虫(***)、中华伞滑刃线虫(***)、树木伞滑刃线虫(***)、托斯卡纳伞滑刃线虫(***)、莱奴尔夫伞滑刃线虫(***)、云杉小蠹伞滑刃线虫(***)和伞滑刃属线虫未定种(***.),调查中未发现重要检疫性病原松材线虫(***)。

会安是越南中部广南省的一个古老贸易港口,始建于16世纪,17、18世纪为其最繁荣的时光,直到19世纪才逐渐衰落。尽管它在越南不是历史最悠久、规模最大的城市,但经历历史动荡、气候恶劣等,它成为越南唯一的一座保存较完整的古老城市。会安这座古城保存了许多华人会馆和有价值的华人文献,尤其是碑铭文献。这些碑铭文献已引起了越南许多研究人员的关注及研究。本文将概述汉文碑铭的特征和形式,并综观来自会安华人会馆及华人社区的文献内容中之相关典型信息。

指出了生态旅游市场需求受到众多因素影响,而且各因素之间存在复杂的相关性,因素度量信息不足,所以可以将生态旅游市场需求预测系统视为灰色系统。以风雅-格邦国家公园为分析对象,基于预测模型GM(1,N),分析诸多因素对越南生态旅游市场需求的综合影响,主要考虑各因素之间的相关度基础上选择最合适的因素建立灰色预测模型,从研究结果中可以得到:影响生态旅游市场需求的因素之间,客源地的教育水平最具有相关性,其次是性别,收入以及旅游资源状况等,灰色预测模型的结果表明:2012～2021年越南生态旅游市场需求增长总体呈现上涨趋势,但增幅较为平缓。

The most common reference electrode (RE) which is used in electrochemical measurements is the Ag/AgCl electrode. In this study, we present a novel solid-state Ag/AgCl planar electrode that was coated with a thin layer of Graphite Oxide (GO) as a protective layer. The Ag/AgCl planar electrode was fabricated by using the photolithography and lift-off method combined with the Ag[NH3]2Cl complex. The GO was produced by Hummer’s method and was deposited on top of the Ag/AgCl layer by drop-casting method. The layers of the fabricated reference electrode were characterized by micro Raman spectroscopy, Scanning Electron Microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX). The responding time of the planar electrode was short and the signal was more stable in comparison to the plainAg/AgCl electrode. The Open Circuit Potential (OCP) measurement with the fabricated electrode as the RE and the platinum electrode as the working electrode in electrolyte solutions which had various pH values was performed with a linear response in pH ranges from pH 5 to pH 8 and the linear correlation coefficient (R^2 = 0.9899). Moreover, the coating of the GO layers also enhanced the durability of the modified electrode. The results showed that the modified Ag/AgCl electrode with a thin layer GO as the protective layer could be used as plana REs for the potentiometric sensors.
