为因地制宜进行土地整治,实现土地空间布局优化,本研究以山西省左云县南辛窑村为例,从全域土地整治视角,运用MCR模型和GIS软件结合的方法分析村域土地资源利用功能适宜性,依此划定土地整治分区,结合村庄规划定位提出相应的土地整治发展策略。结果表明:MCR差值≤0表示生态适宜性较强,差值>0表示建设适宜性强,按照MCR差值由高到低的顺序依次确定土地利用适宜性方向;在国土空间规划“三线”约束下,将研究区划分为小杂粮生产示范区、林草生态保护区、工业生产开发区、宜居核心整治区4类整治区,面积分别为232.02、529.14、5.85、5.88 hm2。整治分区后的土地资源分布格局呈现圈层夹散点的布局结构,具有明显的空间差异性,生态适宜性由中心向四周逐渐增强,与当地生态环境本底相吻合。研究表明,应用MCR模型实施土地整治分区,符合集聚提升型村庄发展要求,实现了耕地集中连片、居住用地集约高效、生态环境充分保护、产业发展有保障的目标,为村庄规划的科学编制和分区土地整治策略提供理论参考。

Spinal muscular atrophy(SMA)is a genetic condition that results in selective lower motor neuron loss with concomitant muscle weakness and *** genetic cause of SMA was understood in 1995 when loss or impairment of the survival motor neuron 1(SMN1)gene was identified as the main contributing factor(Lefebvre et al.,1995).This,in combination with the discovery that humans have a“back-up”gene,SMN2,which can produce low levels(approximately 10%)of the full-length functional SMN protein,has led to the generation of SMA-specific gene *** was traditionally classified according to age of symptom onset and developmental milestones achieved,with life expectancy and severity varying between ***,SMN2 copy number is used as a proxy for the prediction of disease severity,with higher SMN2 copy number typically being associated with reduced severity of SMA,although this relationship is not absolute:some individuals with low SMN2 copy number have less severe SMA phenotypes and vice ***,the etiology of SMA is further complicated by other factors,such as non-typical nucleotide variants and SMN2-independent modifiers of disease severity.

Hall-Petch relation was widely applied to evaluate the grain size effect on mechanical properties of metallic material. However, the sample size effect on the Hall-Petch relation was always ignored. In the present study, the mechanical test and microstructure observation were performed to investigate the combined effects of grain and sample sizes on the deformation behaviors of gold microwires. The polycrystalline gold microwires with diameter of 16 ?m were annealed at temperatures from 100°C to 600°C, leading to different ratios(t/d) of wire diameter(t) to grain size(d) from 0.9 to 16.7. When the t/d was lower than 10, the yield stress dropped fast and deviated from the Hall-Petch relation. The free-surface grains played key role in the yield stress softening, and the volume fraction of free-surface grains increased with the t/d decreasing. Furthermore, the effects of t/d on work-hardening behaviors and fracture modes were also studied. With t/d value decreasing from 17 to 3.4, the samples exhibited necking fracture and the dislocation pile-ups induced work-hardening stage was gradually *** the t/d value further decreasing(t/d lure, and the work-hardening capability lost. As the gold microwire for wire bonding is commonly applied in the packaging of integrated circuit chips, and the fabrication of microwire suffers multi-pass cold-drawing and annealing treatments to control the grain size. The present study could provide instructive suggestion for gold microwire fabrication and bonding processes.

采用高温固相法合成了一系列CaSrNb_(2)O_(7):xSm^(3+)(0.01≤x≤0.08)橙红色荧光粉。并对样品的晶体结构、微观形貌、发光性能、热稳定性等进行了系统地研究。结果表明,样品的激发光谱由一个宽吸收带和一系列尖锐激发峰组成,其中最强激发峰位于406nm处。在406nm激发下,荧光粉最大发射峰位于645nm处,且呈现红光发射。当Sm^(3+)掺杂浓度达到2%时,样品可获得最佳的发射强度。根据Dexter理论分析,其猝灭机制为电偶极-电偶极相互作用。样品的荧光衰减曲线符合双指数衰减变化,且随Sm^(3+)浓度增加,荧光寿命逐渐缩短。在423K的温度下,样品发光强度约为室温下的93%,表明样品具有良好的热稳定性。通过CIE1931软件计算了样品的色坐标,均落在橙红色发光区域。并且荧光粉具有较低的色温和较高的色纯度。说明CaSrNb_(2)O_(7):Sm^(3+)橙红色荧光粉在白光LED领域具有潜在的应用价值。

Identifying factors affecting the survival of individuals is essential for understanding the evolution of life-history traits and population *** numerous studies on this subject in north-temperate environments,there is a lack of equivalent studies at similar latitudes in the ***,we used a 14-year dataset of capture,banding,and resighting to estimate the annual variation in the apparent adult survival probability of a south-temperate population of House Wrens(Troglodytes aedon bonariae).We evaluated temporal variation in sur-vival and the effect of environmental(climatic)and demographic variables(adult abundance,total number of fledglings produced during each breeding season)on survival *** found that the probability of adult survival decreased as the abundance of breeding adults *** density-dependent effect could be related to the resident lifestyle of southern House Wrens,which could determine an intense competition for territories and resources that ultimately would affect their survival.
