The transformation of dilapidated houses in rural areas is not only a livelihood project related to the broad masses of rural people,but also a major project to win the battle against poverty. Luquan Yi and Miao Autonomous County,Yunnan Province,located in the high mountain and gorge area along Jinsha River,is one of the key counties of poverty alleviation and development with a wide range of poverty and a deep degree of poverty. The incidence of poverty is 22. 21%. Housing security is the focus,difficulty and emphasis of poverty alleviation in this county,the number of dilapidated houses is large,the type is complex,the transformation is difficult,and the implementation cost is *** the beginning of 2017,Luquan County has faced difficulties,explored in depth,pioneered and innovated,and completed the renovation of 54 801 dilapidated houses in an all-round way. It created a road full of characteristics and effectiveness of rural dilapidated housing transformation,and explored a set of effective scientific identification and accurate transformation models for rural dilapidated housing worthy of reference and promotion. Successful renovation of dilapidated houses,combined with industrial poverty alleviation,education poverty alleviation,health poverty alleviation and other accurate poverty alleviation measures,have made Luquan County win a decisive victory in the fight against poverty. By the end of December 2018,the incidence of poverty in the county had dropped to 0. 54%,and 115 poor villages( including 83 extremely poor villages) had successfully shaken off poverty. This paper analyzes and summarizes the concrete methods,main effects,characteristics and bright spots,successful experience,and reference significance of the scientific identification and precise transformation mode of rural dilapidated houses in this county,so as to provide a necessary reference for the transformation of rural dilapidated houses in Yunnan Province and even poor counties in similar

The Northeastern margin of Qinghai—Tibet plateau,here refers to the region bounded by Western Qinling fault zone and Longshoushan—Liupanshan tectonic zone, where obliquely compression deformation occurred with the NE\|trending maximum principle axis of stress, with Ordos Massif to the east, Alaxa Block to the north, and Qinghai—Tibet plateau to the southwest. The main structure in this region is Haiyuan—Gulang transpression zone. It consists of a series of active faults: the Haiyuan fault zone, the tianjingshan fault zone, the Yantongshan fault zone and the Niushoushan—Luoshan fault zone.

In this paper, the delay-probability-distribution-dependent stability problem for stochastic neural networks with various time-varying delays is investigated. By considering a new Lyapunov-Krasovskii functional（LKF） concluding more delaypartitioning term and combining free weight matrices and stochastic processing techniques, an improved delay-probabilitydistribution-dependent condition is built in terms of linear matrix inequality（LMI） so that the system is mean square ***, a numerical example is given to verify the effectiveness the proposed criterion.

The calcium carbonate coats on stones developed in soil on the geomorphic surfaces of coarse clastic sediments in arid-semiarid regions contain evident information of age. The thickness of coats can be used not only as a good age indicator for the geomorphic surfaces but also coats themselves can be directly used as dating materials in the ESR method. Through measuring the thickness of carbonate coats on stones in soils on the alluvial terraces in the mouth of the Heishanxia gorge of the Yellow River and ESR dating of layers separated from the carbonate coats, the average of accumulation rates of the thickness of carbonate coats on stones since 1.57 Ma was calculated to be 0.10 mm/ka in the studied area, and a regression equation between carbonate coat thickness and age was also generated. From these research results, ages of T2-T11 terraces of the Yellow River in the studied area were systematically determined, and their values are in turn 18 ka, 94 ka, 139 ka, 215 ka, 305 ka, 410 ka, 495 ka, 742 ka,

随着全球互联网的快速发展,卫星通信逐步出现了与地面通信融合的趋势。在天地一体化进程中,非地面网络采用和地面网络不同波形的融合代价大,直接采用地面波形又会存在性能差异。基于FB-OFDM波形,提出使用GFB-OFDM波形,实现地面系统和非地面系统的灵活波形机制。建立了GFB-OFDM波形的系统模型,理论分析证明了GFB-OFDM接收端可以复用现有的CP-OFDM的接收算法,且峰均比更低。在AWGN信道环境中,仿真验证了GFB-OFDM复用CPOFDM接收端的情况下,误比特率性能相较CP-OFDM降低在0.1 dB以内,同时PAPR比CP-OFDM降低了1~7 dB,所以GFB-OFDM是一种适用于天地一体化的波形技术。
