论油气储运设施安全的重要性

油气储运设施是连接石油工业产、运、销各环节的纽带,其安全重要性日益凸显。介绍了油气储存和运输设施的分类依据及主要类型;从储运介质的易燃易爆和毒害性、油气储运设施易构成重大危险源两个方面论述了油气储运设施安全的重要性;通过总结近年发生的大连＂7.16＂爆炸事故、大型储罐火灾事故及油气管道泄漏事故的教训,指出第三方破坏是导致管道发生泄漏事故的主要原因,而打孔盗油又是其中的重要因素;提出了在工程立项、设计、施工及运行管理的各个阶段加强安全管理的具体措施。

对宁夏固原市做好水库防洪蓄水调度的对策及建议

实现控制洪水向洪水管理转变,从综合的角度考虑洪水,它不仅是灾害,在一定条件下也可能变成资源;从风险的角度去考虑洪水,它是有风险,在降低或转移同时会带来可观的收益。     

Study on the Stability of Blue-tongue Virus after Long Time Storage in Cold Room

In order to understand the stability of blue-tongue virus (BTV)storage in cold room for long time, 18 tissue samples which were kept in 4℃ for 10 to 15 years were test by Real-time PCR, and 10 blood samples which were kept in 4℃ for 15 years were subjected to virus isolation process, then was proved by monoclonal antibody staining,research results showed all old samples were positive in Real-time PCR, further more, 5 live virus were isolated from 10 old blood samples. The results suggested the stability of BTV was higher than we thought before.     

二氧化碳输送管道关键技术研究现状

碳捕集与封存作为减少温室气体排放的重要手段成为全球研究热点，管道运输是该技术得以实施的关键环节。当CO2处于超临界或密相状态时，其具有液体的密度、气体的粘性和压缩性，对于管道运输是最有效率的。由于管输CO2的特殊性质，CO2输送管道与碳氢化合物输送管道存在不同；由于海洋环境的复杂性，CO2海上输送管道与陆地输送管道存在不同。系统总结了实现CO2管道输送需要解决的关键技术问题，着重介绍了CO2输送管道流动保障和延性断裂扩展领域的研究进展，指出CCS作为大规模减少温室气体排放的重要选项，开展与之相关的基础研究十分迫切。（图3，参44）     

果蜡处理对低温贮藏下采后菠萝果实激素的影响

以菠萝品种‘巴厘’的果实为试材，研究果蜡处理对低温贮藏下采后菠萝激素的影响，结果表明：果蜡处理降低了冷藏菠萝果实脱落酸(ABA)、赤霉素(GA)和玉米素(ZR)含量，增加了吲哚乙酸(IAA)含量，并且ABA 和GA含量均与冷害指数极显著相关(P＜0.01)，相关系数分别是0.879和0.909。表明低温胁迫下采后菠萝的ABA和GA与抗冷性密切相关，果蜡处理降低了ABA和GA含量，从而提高菠萝抗冷性。     

蜡蚧轮枝菌防治植物病虫害研究进展

蜡蚧轮枝菌在蔬菜病虫害防治中有很大开发潜力。就蜡蚧轮枝菌的致病性、环境条件对其生长的影响、储藏期存活率及在生产中应用的概况的研究进展进行了综述。研究进展表明,该种真菌既可以防治粉虱、蚜虫、蓟马等蔬菜害虫,又可以防治蔬菜的白粉病、锈病等。     

昆虫病原线虫的贮存和剂型研究进展

阐述了昆虫病原线虫的贮存原理,介绍业已建立的昆虫病原线虫贮存方法及其优缺点,影响昆虫病原线虫贮存效果的主要因素,并讨论了昆虫病原线虫剂型制备方法。     

超干处理和贮藏对番茄和辣椒种子生活力和活力的影响

试验采用氧化钙为干燥剂对番茄和辣椒种子进行超平处理和贮藏，以研究其对种子生活力和活力的影响。结果表明，番茄种子水分降至3．77％、辣椒种子水分降至3．86％，未发现对种子生活力和活力有明显的影响；对不同含水量的番茄和辣椒种子室温密闭贮今6个月后的调查结果发现，超低水分种子生活力和活力较高，细胞膜能保持较好的完整性，脱氢酶活性和呼吸强度较高。由此可见超干贮藏有利于保持番茄和辣椒种子的生活力和活力。     

Seedborne fungi detected on stored solanaceous berry seeds and their biological activities

We isolated 629 fungi from 1296 berry seeds of solanaceous plants, including tomato (Lycopersicon esculentum), eggplant (Solanum melongena), bell pepper (Capsicum annuum), and red pepper (Capsicum annuum var. annuum) preserved for long and short terms. The isolates were classified into 22 genera excluding unidentified fungi, and the fungal floras were divided into two types: the tomato–eggplant and pepper groups. The results of cluster analysis with unweighted pair-group method with arithmetic average also supported these groups. Most tomato seeds infested with Geotrichum candidum germinated and grew the same as uninfested seeds. Cladosporium sphaerospermum and Arthrinium sp. isolated from eggplant seeds strongly suppressed germination, and Penicillium variabile suppressed seminal root elongation on eggplant. Alternaria alternata, Botrytis cinerea, and Myrothecium verrucaria detected from red pepper or bell pepper seeds were pathogenic to the fruits and the seedlings after artificial inoculation.
