“一带一路”倡议提出以来,中国与东盟的战略合作日益紧密,中国—东盟关系成为亚太区域合作中最为成功和最具活力的典范。作为“一带一路”建设的重要推进区域,中国和东盟秉持绿色发展理念,深入加强“中国—东盟命运共同体”建设。但目前中国—东盟经济绿色合作中仍存在整体合作环境不佳、绿色合作能力有限、缺乏合作深度与广度等困境。应从改善整体合作环境、提升绿色合作能力、创新绿色合作模式、加强碳关税协调机制等方面深入构建中国—东盟绿色经济合作的可能路径,推动中国—东盟双方经济绿色高质量发展、促进中国与东盟经贸合作提质升级。

针对古汉山矿原工作面之间留一定宽度的煤柱,在开采时存在资源浪费、巷道应力集中支护困难、采掘接续紧张等问题,综合运用理论、模拟以及现场试验等手段方法,提出切顶留巷技术。结果表明,切顶后采空区侧基本顶随采随落,矸石及时支撑覆岩并抑制其回转下沉。提出利用锚索强化顶帮结构,确保沿空留巷的稳定。沿空留巷后帮部收缩量为485 mm,顶底板收缩量为686 mm,底鼓量达500 mm,底鼓较大的主要原因是留有1~2 m的底煤,底板强度偏低。经简单卧底修复后能够达到二次使用的要求,为厚煤层放顶煤开采条件下实施沿空留巷技术提供科学参考。

Based on the output data from 1997 to 2000 obtained by the MITgcm's(general circulation model)adjoint assimilation method, volume, heat and salt transports through the Luzon Strait are calculated. The results indicate that there are obvious different characteristics between 1997 and 1998~2000 on the transports through the Luzon Strait. During 1997, the Luzon Strait had a mean net westward transport of 3.93 ×106 m3/s with a maximum transport of 7.34×106 m3/s in October. During 1998~2000, the Luzon Strait possessed an annual mean eastward transport of 0.93 ×106 , 1.80 ×106 and 1.00 ×106 m3/s respectively with a maximum eastward transport of 4.10 ×106 /3.31 ×106 m3/s in July 1998/ 1999 and 2.06 ×106 m3/s in April 2000, respectively. Moreover, the transports in 1997 indicated a difference from the other years, i.e., that the ranges of westward inflows expanded more obviously to north of the Luzon Strait and downwards exceeding those of the other years. The westward inflows expanded horizontally to the north part of the Luzon Strait until 21o N.

The studied agriculture\|pasture interlacing zone has its specific natural conditions, at which the natural systems are unstable, their self\|regulation capability is low and the equilibrium is easily broken, and hence the habitat is fairly vulnerable. During last 20 years the increasing population and livestock, over\|reclamation, over\|pasturing, over\|deforesting, and other intensified negative human activities in the zone resulted in coarsening of surface soil, decrease of organic mater content in soil, reduction of vegetation coverage, variation and degradation of flora structure, and hence in desertization of the land, although average of gales and sandstorms some decreased and the climate tended to be better in the region. However, the frequent sandstorms occurring in the springs of last and present years has attracted much attention. Investigations confirmed that the main cause for the phenomena is the unreasonable human activities rather than the natural factors.

Large-scale and diverse businesses based on the cloud computing platform bring the heavy network traffic to cloud data ***,the unbalanced workload of cloud data center network easily leads to the network congestion,the low resource utilization rate,the long delay,the low reliability,and the low *** order to improve the utilization efficiency and the quality of services(QoS)of cloud system,especially to solve the problem of network congestion,we propose MTSS,a multi-path traffic scheduling mechanism based on software defined networking(SDN).MTSS utilizes the data flow scheduling flexibility of SDN and the multi-path feature of the fat-tree structure to improve the traffic balance of the cloud data center network.A heuristic traffic balancing algorithm is presented for MTSS,which periodically monitors the network link and dynamically adjusts the traffic on the heavy link to achieve programmable data forwarding and load *** experimental results show that MTSS outperforms equal-cost multi-path protocol(ECMP),by effectively reducing the packet loss rate and *** addition,MTSS improves the utilization efficiency,the reliability and the throughput rate of the cloud data center network.

In the present study, we have developed the method brought forward recently for protein design based on the relative entropy. The new approach can be used in more common situation other than the special limits in the anterior method. The results indicate that our generalized method has increased the prediction precision for protein sequence and will be in favor of the study for protein design.
