Abstract: 危机预警与危机应急处理同样重要。前者重在预防,后者重在治疗。建立系统、完整的社会突发事件预警机制是现阶段我国构建应对社会突发事件政府危机管理机制的前提和基础。随着“和谐社会”治理理念的提出,尽快建立起有效应对社会突发事件的危机预警机制也就成为预防危机发生、维护社会稳定、构建和谐社会的重要机制之一。

Abstract: Carbon counter electrode was fabricated using high surface area mesoporous carbon (MC) as catalytic material at low temperature. The integral structure and the photovoltaic performances of dye―sensitized solar cells (DSC) consisting of the obtained carbon counter electrode were emphatically optimized. The results show that both contact interface among MC particles and that between carbon catalytic film and substrate are improved by adding Triton X100 into MC slurry, leading to an increase of 7.1% in the efficiency of DSC. With the increasing thickness of TiO2 film, the efficiency of DSC sharply increases at first and tends to stabilization later on. The change in the efficiency is the result of competition between the adsorption amount of dye and the transmission path of electron in the TiO2 film. The resistance of electrolyte is reduced by mixing tributyl phosphate into electrolyte, resulting in an increase of 23.1% in the efficiency of DSC. The optimum efficiency of DSC employing carbon counter electrode reaches 4.82%.

Abstract: Along with the fast development of communications in the littoral,the engineering to lay optical cables in the sea bed is more and more frequently being done and interlaced optical cables are incidentally destroyed by artificial and natural causes or the request of ocean engineering.This demands to survey well and truly locate the position of optical cables.We used G-880 cesium optical-pump marine magnetometer to survey magnetic fields between Luchao port,big mountain and small mountain.We find that communication optical cable can arouse some magnetic anomaly from 8 nT to 20 nT,and the power cable can arouse an aomaly about(2 000 nT).Basing on the anomaly shape,we can confirm the positions of the optical cable and power cable.And according to the makeups of optical cable and power cable,we can analyze and discuss the source of magnetism anomaly.

Abstract: 通过田间小区试验研究了不同施K量对烤烟K素吸收利用效率及产量和品质性状的影响.结果表明:K在烤烟各器官的累积量和含K量均表现为叶>茎>根,随着施K量的增加,烟叶和烟株累积量和含K量显著增加,而K肥利用率,K素干物质生产效率和K素利用效率显著下降.烟叶产量和外在品质在施K量0~315kg/hm2范围内均随施K量的增加而提高,超过315kg/hm2则下降明显.增施K肥显著提高烟叶含K量、还原糖含量,降低总N、Ca、Mg、烟碱含量.相关分析表明,K素吸收利用效率与烟叶产量品质密切相关.

Abstract: The existing mobility support scheme in Host Identity Protocol (HIP) does not support micro-mobility. In this paper, a new mobility support scheme in HIP based on dynamic hierarchical location management is proposed. The Internet is separated into some autonomous areas while each autonomous area is separated into some registration areas. When the node moves in the same registration area, it updates its registration at Local RendezVous Server (LRVS). When the node moves in the same autonomous area, it updates its registration at Gateway RendezVous Server (GRVS). The node selects LRVS and determines the optimal size of registration area according to its mobility and packet arrival rate. Analytical results show that the new scheme outperforms the existed mobility support scheme in terms of reducing the overall signaling cost.

Abstract: 不同的植物对铝胁迫的生理响应不同,因而对铝毒的耐性也不相同.设置5种铝浓度,进行砂培法处理,研究了4种我国南方红壤广泛分布的草本植物--牵牛(Pharbitis nil)、望江南(Cassia occidentlis)、光头稗(Echinochloa colonum)和合萌(Aeschynomene indica)的种子萌发、光合色素、脯氨酸含量、丙二醛(MDA)含量、可溶性糖(SS)含量、质膜透性(MP)、过氧化氢酶(CAT)活性以及过氧化物酶(POD)活性的变化.结果表明铝对4种植物的生理特性都有明显的影响.4种植物的种子在10 000 mg·L-1 Al3 处理条件下都不能萌发.2 000 mg·L-1 Al3 处理都不利于4种植物的生长,与对照相比,2 000 mg·L-1 Al3 处理时4种草本植物叶绿素和叶绿素总含量显著降低(p<0.05);MDA含量和MP显著增加(p<0.05);脯氨酸含量极显著增加(p<0.01);POD和CAT活性极显著降低(p<0.01).中低铝(80和400 mg·L-1)处理时,牵牛和合萌与对照相比,MP和MDA含量降低,POD和CAT活性升高;望江南的反应与牵牛和合萌的反应相反;光头稗在80 mg·L-1 Al3 处理时,与牵牛和合萌的变化一致,在400 mg·L-1Al3 处理时,则相反.植物在中低铝处理条件下,通过维持较高的POD和CAT活性和脯氨酸、叶绿素含量,较低的MP和MDA含量来增加其对铝的耐性.
