The Planning, Organization and Management of Post-disaster Reconstruction of the Lushan Earthquake Based on the Local as the Main Body

A new organization and management mechanism with the local government as the main body was created during the post-disaster reconstruction of the "4. 20 " Lushan earthquake,in which the experiences and lessons were drawn from the "5. 12"Wenchuan earthquake. Correspondingly, the local government conducted an exploration of the organization and management mode in the field of planning and construction. The effective experiences have been accumulated, including working out a full coverage planning,taking the leading part in the urban-rural planning,and exercising whole space control over the disaster area. An innovation management mode named as "Five Generals Pattern"was implemented in the construction projects. In view that the rural housing reconstruction was a weak link, a new approach to improving the construction management was investigated,by means of strengthening on-site supervision,establishing a technical platform,and bolstering public participation.

Dynamic genetic analysis for body weight and main length ratio in turbot Scophthalmus maximus

The objective of this study was to estimate genetic parameters of body width(BW)to body length(BL)ratio(BW/BL)and of body weight traits(BWT)in turbot,and to elucidate the genetic mechanism of the two traits during ontogeny by dynamic genetic analysis.From 3 to 27 months,BW,BL and BWT of each communally stocked fish were measured every 3 months.The BW/BL ratio was measured at different sampling ages.A twotrait animal model was used for genetic evaluation of traits.The results showed that the heritability values of BW/BL ratio ranged from 0.2168 to 0.3148,corresponding to moderate heritability.The BWT heritability values ranged from 0.2702 to 0.3479 corresponding to moderate heritability.The heritability of BW/BL ratio was lower than that of BWT,except at 3 months of age.Genetic correlation between BW/BL ratio and BWT decreased throughout the measurement period.Genetic correlations were higher than the phenotypic correlations.The current results for estimating genetic parameters demonstrate that the BW/BL ratio could be used as a phenotypic marker of fast-growing turbot,and the BW/BL ratio and BWT could be improved simultaneously through selective breeding.

Analysis of the Main Body the Object and their Relationship Concerning Research of Traditional Chinese Medicine

This paper is the analysis of the main body, the object and their relationship concerning research of traditional Chinese medicine. The result proved that the main body of research of traditional Chinese medicine is researchers who possessed the fundamentals of traditional Chinese medicine. It is the objects of research of traditional Chinese medicine that origin of a class of traditional Chinese medical literature consisting of herbals which focus on descriptions of individual drugs; the relationship of the technological process of preparing Chinese medicine, as by parching, roasting, baking, steaming, soaking, and simmering, etc.;and technology of separating, extracting and purifying for composition; traditional Chinese medicine dynamics of one of the 12 two-hour periods into which the day was formerly divided before the introduction of western chronology; compatibility of medicines in active compositions; patent, effectiveness for a given period of time and constantly changing of traditional Chinese medicine.The relationship between the main body and the objects was that the former depends on the latter ones and the main body has subjective initiative as fully as possible.

Study of main body element of crustal strain and its relationship with moderate-strong earthquakes

In this paper, progress in strain study of blocks and faults by GPS data are discussed, and the concept that active structures between blocks are the main body of crustal strain is clarified. By energy transfer principle of elastic mechanics, the relation between strain around faults and tectonic force on fault surfaces is set up and main body element model of crustal strain is constructed. Finally, the relation between mechanical evolution of model and seismogenic process of Kunlun earthquake （Ms=8.1） is discussed by continuous GPS data of datum stations. The result suggests that the relatively relaxed change under background of strong compressing and shearing may help to trigger moderate-strong earthquakes.

Research on Characteristics of Main Body and Role of Farmers and Government in Socialist New Village Construction

This paper expounds the connotation of main body of new socialist village construction,and the duplex main body characteristics of farmers and government.It points out that the main body of society should be the state holding public power,and the main body of nature or practice is the farmer who participates in production and living activities in rural areas and supports the existence of rural society.It also expounds the dominant position of duplex main body in new village construction,wherein the government is the main body which administers public power in the field of public power in new village construction,while the farmer is the main body who administers private rights in the field of non-public rights in new village construction.It generalizes and unravels the role of duplex main body of farmers and government in new village construction,and analyzes the relationship of role of duplex main body between government and farmers as follows:the government dominates over rural development,and the government,as main body,plays dominant role in the field of rural public power and construction of social environment,while the farmers are main participators and constructors,who play significant role;in construction of rural non-public power field,the farmers play the role of main body,and the government plays the role of guidance and service.In new village construction,the government and farmers play the role abreast,which is an important prerequisite and guarantee of constructing new village.In the process of government's fulfilling responsibility in new village construction,the outdated administrative concept exists,and in the process of administering and promoting new village construction,the farmers' quality is yet to be promoted.As for these problems,three countermeasures are put forward as follows:transform concept;transform style of work and transform and exert advantage of organization.

以糖厂为主体的甘蔗机收推进模式

近年来,我国甘蔗种植面积逐年减少,切段式甘蔗联合收获机保有量大幅增加,机收率却多年低位徘徊。针对这一问题,本文从方法论视角阐明当前甘蔗产业生产关系与新质生产力之间的矛盾,是机收推进缓慢的主要原因。提出以提高甘蔗产业的竞争力和促进产业可持续发展为目标,调整甘蔗产业当前生产关系,将当前生产关系中的各方组成机收推进联合体,构建以糖厂为主体的机收推进模式。该模式以免费或低价机收为杠杆,糖厂组织、协调、管理甘蔗机械化生产,实现了糖厂有稳定优质蔗源、机收组织效益稳定、蔗农获得免费(或低价)砍收甘蔗,达到多方共赢,有利于稳定甘蔗种植面积和甘蔗产业可持续发展。以该模式为抓手,建立试点并推广应用,在当前条件下,有望打破目前机收推进缓慢僵局,实现甘蔗机收快速推进。

宽体飞机地面主轮协同转弯控制律设计

主轮协同转弯技术能有效提高飞机的地面机动性,降低主起落架在转弯过程中受到的附加侧向扭矩,减小重载飞机地面转弯半径,但目前实现此技术的前主轮转角控制律设计方法尚不明确。提出以主起落架受力为约束条件,计算不同滑行速度下的前主轮转角关系,在全速度范围内进行分段选择并离散化,据此设计前主轮协同转弯控制律,以原理样机为对象进行仿真分析,验证了该控制律能有效降低两侧主起落架扭矩和的峰值。提出的设计方法对多轮系地面运载装备的复合转弯控制律设计具有一定的理论指导意义。

城市空间水体热环境效应研究——以重庆市主城七区为例

水体作为地表热环境的重要敏感因子,对缓解热环境效应具有重要作用。基于2003、2011和2019年土地覆被数据与热环境指数数据,以重庆市主城七区为例,将景观格局与热环境相结合,利用空间分析和相关性分析探究地表重要覆被对水体降温能力的影响以及水体对热环境效应的具体调控机制。结果表明:①水体相比裸地、植被、建成区覆被类型,其热环境指数处于最低水平,与热环境效应呈显著的负相关性,有良好的降温效果,且单位水体比单位植被降温作用更强;②水体与植被之间存在相互作用,且随着植被比例增加,水体的降温效果越差;在非城市用地中,植被的降温效果最好,随着城市发展密度的增加,水体的降温效果也逐渐增强,超越植被调节热环境的能力;③水体自身热环境与水体形状指数无关,与面积、长度、宽度、深度因素有关,且在一定范围内,随着面积、长度、宽度和深度的增加,降温效果有所提升;④随着缓冲距离的增大,水体的降温效果逐渐下降,河流的最佳降温范围为200 m左右,水塘和水库的有效降温范围在300 m左右。为促进城市热环境的改善,未来应因地制宜利用城市空间增加绿化、加强水体循环等机制来缓解城市热环境效应,实现城市生态的稳定和可持续发展。
