Evaluation on the Damage Evolution of the CRCP+AC Composite Pavement by the Concrete Dameged Plasticity Material Model

In the study on the CRCP+AC composite pavement, the form and distribution pattern of cracks are two important factors influencing the performance and the lifetime of the pavement. The concrete damaged plasticity material model incorporated in the general purpose finite element software named ABAUQS was adopted to describe the mechanical characteristics of the CRC slab. Combining with the temperature field database drawn from the three-dimensional transient heat transfer analysis, the structural damage under the condition of temperature changing is analyzed. The structural damage evolution and the crack behavior of the CRC slab subjected to the thermal-mechanical coupling condition are further analyzed, which suggests that the role of the asphalt concrete surface is not confined only to the scope of improving the performance of the road, its capacity for improving the stress state of CRCP slab is worthwhile to be affirmed. And the reasonable thickness of AC layer should be designed in consideration of the thermal contraction and damage properties of the CRC slab comprehensively.

养殖业兽医社会化服务模式分析

我国养殖业的兽医服务方式多样,其中兽医社会化服务能力不足的问题由来已久,亟需发展壮大。在有关政策法规的指导下,多地结合自身条件,因地制宜探索推行了兽医社会化服务模式。本文介绍了兽医服务公司承接、"企业+农户"、"购买产品+服务"、合作社承接、科研院所服务、信息化平台服务等6种养殖业兽医社会化服务模式,并对不同模式的服务组织、服务内容、服务机制、服务特点等进行了分析,其中"兽医服务公司承接模式"和"合作社承接模式"的社会化程度较高,也是目前基层最为推广的模式。这提示当前的兽医社会化服务组织需进一步扩大服务范围、拓展服务对象、提升技术能力,推动整体升级转型。     

What can we learn from visual and objective assessment of non-lame and lame horses in straight lines,on the lunge and ridden?

Traditionally and when using objective gait analysis, horses with and without lameness are most frequently assessed trotting in straight lines in hand. Valuable information can be gained from assessment on the lunge and ridden in walk, trot and canter. No studies have quantified lameness during all aforementioned conditions and gaits at once, despite the rapid recent development in equine gait analysis methods. Objective methodologies, previously confined to gait laboratories, are currently being expanded to field technologies using accelerometers and inertial measurement units (IMUs). This publication aims to describe normal gait and the spectrum of pain-related gait abnormalities and other musculoskeletal adaptations to pain that can be observed in walk, trot and canter during in hand and ridden assessment in straight lines and on a circle on hard and soft surfaces. In addition, it aims to describe briefly how IMUs have been used and areas for further research in the light of what we know from subjective lameness examinations and what is possible with IMUs.     

全膜覆土穴播种植冬小麦对旱地土壤微生物数量及生物量的影响

[目的]揭示全膜覆土穴播种植方式对土壤微生态环境的影响,为其进一步推广应用提供参考依据。[方法]采用田间试验,研究不同覆膜种植方式对冬小麦各生育期土壤微生物数量和微生物量的影响。[结果]全膜覆土穴播方式可明显增加冬小麦各生育期的土壤微生物数量(除自生固氮细菌)以及微生物量C和N。与传统栽培方式相比,全膜覆土穴播方式和全膜不覆土穴播方式土壤细菌、放线菌、真菌分别平均提高32.07%和10.23%,31.27%和10.57%,44.56%和26.51%;氨化细菌和硝化细菌分别平均提高32.54%和37.80%,79.20%和107.22%;微生物量C和N含量分别平均提高29.90%,20.68%%和29.41%,18.02%。各处理土壤微生物数量和微生物量整体从小麦返青期开始升高,到拔节期或抽穗期达到峰值,生长后期有所下降。[结论]全膜穴播方式下土壤微生物数量和微生物量土壤随土层的加深呈减少的趋势。全膜覆土穴播方式有利于冬小麦土壤微生物数量和微生物量的提高。

不同密度和种植方式对玉米产量的影响

以大丰30为材料,研究了不同密度和种植方式对玉米产量的影响,结果表明,合理密植有利于提高玉米产量,在一定范围内,随着种植密度的增加,玉米产量随之增加,种植密度达到82 500株/hm2时,产量最高;而试验所设的3种种植方式对玉米产量没有太大的影响。
