超深水永乐X区潜山气藏具有储层非均质强、纵向岩性组合多样的特征,传统生产测井技术在落实储层产出特征时存在局限性。采用分布式光纤测温技术测试获得了YL1井产能测试生产层段的温度数据,结合渗流力学和流体力学理论,建立了气藏渗流和井筒管流温度—压力场双耦合模型,计算了气井产出剖面变化引起的温度响应特征。采用Levenberg Marquart(LM)反演算法实现了YL1气井产出剖面定量解释分析。研究结果表明,气井多层测试时高渗层对应井筒温度下降斜率大,温度变化速度快,温降大,通过温度剖面可以作为判断高渗地层、裂缝或非产层产出贡献;利用建立的分布式光纤温度产出剖面解释方法,定量评价获得了砂砾质风化带、风化裂缝带和内幕裂缝带产出贡献,解释结果与录井气测率具有正相关性,且与地质认识吻合,证明了解释理论的可靠性。研究结果对分布式光纤温度监测多层气藏产出剖面技术的推广具有重要理论及应用价值。

作者： HUANG Zhi-tong HUA Yi-qiang lu Yue-ming JI Yue-feng, XU Da-xiong Key Laboratory of Optical Communications and Lightwave Technologies Beijing University of Posts and Telecommunications Beijing 100876 China

This article discusses the issue of resource conflict in the generalized multi-protocol label switching （GMPLS） controlled optical network. Based on the analysis of the current random rebuilding mechanism and its drawbacks, this article presents two enhanced solutions for improvement, namely, the priority-based resource allocation mechanism and the network management system （NMS） based sequential resource allocation mechanism. Experimental results show that the presented mechanisms perform better than the original random rebuilding solution in terms of the connection setup/recovery time and successful rate.

Huanglongbing （HLB, or citrus greening） is the most destructive disease of citrus, which is associated with Candidatus Liberibacter asiaticus （Las）. Few management options are available, aside from preventive measures such as removing infected plants, planting disease-free seedlings, and managing the insect vector. In this study, we assessed the efficacy of thermotherapy against HLB under controlled greenhouse conditions. A total of 60 two-year-old, graft-infected Citrus reticulata Blanco plants were used. The plants were randomly divided into three groups （45℃, 48℃, and untreated control）, with five plants/replicate （rep） and four reps/treatment. The treated plants were placed in phytotrons for a 4-h treatment session, repeated once per week for three consecutive weeks. Disease remission was observed eight weeks post-treatment. Real-time PCR assays revealed that Las titers in HLB-affected seedlings were significantly reduced in both 45 and 48℃ treatments four weeks after treatment, with the exception of eight plants. In contrast, Las titers in the untreated control plants increased significantly during the same period, with a maximum increase of 28-fold. Except for seven plants, Las titers in the new flushes of treated plants decreased more than 90% eight weeks after treatment. Las titers in mature leaves of treated plants decreased 56 and 60% in average at 45 and 48℃, respectively, eight weeks after treatment. The HLB symptoms and Las titer of seedings were markedly alleviated eight weeks after treatment in both 45 and 48℃ treatments. Our results laid a good foundation for the further development of citrus free-disease seedling cultivation and Huanglongbing control in the field. The whole plants were replaced for scion or branch in previous as the research object in this study, and the expression of Huanglongbing symptoms combined with real-time polymerase chain reaction （PCR） were used to evaluate the effect of heat treatment in the greenhouse.

As an atomic emission spectroscopy technique, laser-induced breakdown spectroscopy (LIBS), first proposed by Breech and Cross in 1962 [1], has attracted much academic and industrial interest for its unique properties. By focusing a pulsed laser onto the surface of a target, laser-induced plasmas can be generated. The simplicity of sample preparation of the laser ablation process enables LIBS to directly analyze solid, liquid, or gaseous materials in the atmosphere, making it a convenient tool for chemical analyses. The unique features of LIBS such as requiring little or no sample preparation, allowing remote detection, and facilitating multiple elemental analyses have contributed to its rapid development in recent years.
