不能犯问题由于在我国刑事立法中没有明确规定,给司法实践带来了很多争议,侵犯人权的现象时有发生。针对我国刑法理论关于不能未遂犯的含义、本质及存在的不完善之处等几个问题的研究,得出我国不能未遂犯的应有含义,即不能犯并非均构成犯罪,而可分为不能犯未遂与不可罚之不能犯。  相似文献

<正>一、加快产品结构调整步伐,明确产品结构调整重点产品结构调整是企业永恒的课题,同时又是一个持续演变进化的过程,不能一蹴而就。我们讲产品结构调整,不能脱离市场,也就是说要以市场为导向,不能脱离企业的资源配置特点,就是说不能干我不能干的事情,更不能为调整而调整。根据杭机股份的现状和市场需求的特点,产品结构调整重  相似文献

跳奏是钢琴演奏中最基本的弹奏方法之一.在钢琴演奏中,为避免"见点即跳"的现象出现,要求我们不能脱离音的时值谈跳音,不能脱离记谱方式的不同谈跳音,不能脱离作品的时代风格谈跳音,不能脱离作品的情绪谈跳音,不能脱离手的不同动作部位演奏谈跳音.  相似文献

对于不能犯的认识及其是否具有可罚性,不同国家的刑事立法和刑法理论相差很大。在我国刑法体系中,无论从立法层面,还是从学术研究层面,均没有对不能犯给出合理而全面的解释,使得对不能犯的认定与判断难免出入人罪。我国应在尊重刑法规范的基础上修订现行《刑法》,增设不能犯条款,以便在认识及处理不能犯案件时有法可依。  相似文献

1故障分类 TY220推土机不能行走是最常见的故障之一。不能行走按液力机械传动油的温度高低可分为冷车和热车两种状态:冷车不能行走是指冷车启动后,发动机中速运转,然后挂挡,推土机不能立即起步;热机不能行走是指在正常推土过程中,随着油温的升高(在正常油温范围内),推土机越来越无力(此时发动机工作正常),甚至在无负荷的情况下行走也困难。  相似文献

基于神经网络的人力资源管理效益评价   总被引:1,自引:0,他引:1  
一、引言 人力资源管理效益评估是对人力资源管理总体活动的成本-效益的测量,并与组织过去绩效、类似组织的绩效、组织目标进行比较.管理学家詹姆斯·哈林顿说过:"度量是关键.如果你不能度量它,你就不能控制它.如果你不能控制它,你就不能管理它.如果你不能管理它,你就不能改进它".  相似文献

市场机制在资源的配置中起着非常重要的作用,通过市场的自发调节,有限的资源可以得到最有效的利用,从而达到效率最大化,因此,在发展市场经济的过程中,一定要重视市场机制的对资源重要调节作用。但是,市场机制不是万能的,尤其是市场不能完全解决经济中的外部性,不能提供社会需要的大量公共物品,不能解决收入分配不公平问题,不能解决市场垄断问题。当市场不能有效地调节资源配置时,市场失灵了,这时政府就要采取有效措施进行宏观调控,解决市场失灵问题。  相似文献

Surface pollen from various montane vegetations in Shalixian Mt.and Lepei Mt.of central and northern Taiwan have been explored and analyzed.The pollen data were used to simulate vegetation types by using the biomisation technique,Computing three matrixes of pollen taxa , plant functional types and combined biomes,vegetation types at each site have been finally defined through the fuzz selections of a tie-breaking rule.The results show that surface pollen data can simulate the subtropical Castanopsis and Cyclobalanopsis forests.alpine warm-temperate Quercus and Quercus-Pinus forests,and alpine temperate/cool-temperate conifers of Tsuge-Picea and Picea-Abies forests.Simulated elevations of the,forests are similar to actual locations of the forests.This study can add vertical surface pollen data for extending investigation of various vegetation types in China,provide PFT schemes and vegetation types in low-latitude and montane areas,and be applied as modern analogues for fossil pollen in order to reconstruct Quaternary vegetations.  相似文献

在光镜下观察新鲜花粉真实形态的制片方法   总被引:1,自引:0,他引:1  
很多植物的新鲜花粉经过Erdtman醋酸酐分解法、洋红等染料和胚胎学制片处理后,形状上会发生很大的变化,这种形态上的变化常常被忽视.本文介绍一种在光学显微镜下,利用油镜油(或纯乙醇)对新鲜花粉进行处理的制片方法.这种方法通过油镜油对花粉覆膜或浸透来改变花粉的透光特性,避免了花粉接触水后吸水膨胀改变形态,使制片不仅可以观察花粉(包括四合花粉)的真实形态、表面纹饰,还能观察到花粉的层次结构.  相似文献

This preliminary investigation focuses on the comparison of the recent pollen precipitation and its related vegetation of eight different plant communities in the Alashan Region, the most western part of the Inner Mongolia Autonomous Region. Most zonal and azonal communities can be well identified by their pollen spectra. Relative pollen production factors of various plant taxa have been calculated and the following sequences from over-to under represented taxa have been found for zonal vegetation: Chenopodiaceae,Artemisia, Ephedra, Nitraria, Reaumuria, Calligonum, Zygo-phyllum; and for azonal vegetation: Peganum, Populus,Tamarix, Lycium.  相似文献

Fifty-six surface pollen samples from different vegetation zones in the Yili Basin,western Tianshan Mountains,Xinjiang were analyzed to examine the relationships between the surface pollen assemblages and the original vegetation.A pollen analysis and a vegetation investigation with a discriminant analysis show that the pollen assemblages greatly differ across disparate vegetation zones.Twelve pollen taxa can be used as significant types for vegetation reconstruction in the basin.These taxa were the most abundant in the surface pollen samples.Cupressaceae pollen percentages were greater than 1%in Cupressaceae shrubs.More than5%of Picea pollen indicates the growth of a Picea forest within 5 km.The subalpine meadow that is distributed widely in the basin is characterized by high content of Artemisia,Chenopodiaceae,Poaceae,Picea,Asteraceae,Taraxacum and Arenaria pollen types.The Artemisia-Chenopodiaceae-Poaceae-Cannabaceae pollen assemblages indicate the presence of montane steppe in the area.Artemisia and Chenopodiaceae pollen dominate the desert steppe and Populus forest.Artemisia pollen percentages were greater than 60%in the Artemisia desert,whereas Chenopodiaceae pollen percentages exceeded 65%in the Chenopodiaceae desert.The Artemisia/Chenopodiaceae(A/C)ratios reflect the vertical moisture changes in the Yili Basin.The mean A/C ratios were greater than 1.2 in the subalpine meadow and montane steppe that occupy the humid zone in the basin.These ratios were between1 and 1.2 in the Cupressaceae shrubs,desert steppe,Populus forest and floodplain meadow.The ratios were less than 0.5 in the Chenopodiaceae desert,which is an arid environment.  相似文献

Chromosome engineering of pollen wheat is the new procedure combining anther culture and chromosome engineering techniques. It could transfer useful alien genes into wheat varieties, enhancing genetic diversity for investigation of genetics and breeding. In the present study, two new procedures, at genome level and single chromosome level, were established. Compared with the classical chromosome engineering, the chromosome engineering of pollen wheat has the following main characters: (i) diversity of products, (ii) rapid stability and (iii) high efficiency of selection. Experiments indicated that chromosome engineering of pollen wheat is an efficient way for creating alien translocation line, especially non-Robertsonian translocation line. Meanwhile, using this procedure combined with comprehensive identifying methods, the investigation of useful genes and molecular markers on rye chromosomes 1R and 6R respectively has been done. The roles and relationships between chromosome engineering of pollen wheat and gene engineering on crop improvement were discussed.  相似文献

The substructure of pollen exine in Cedrus deodara (Roxb.) Loud. and Metasequoia glyptostroboides Hu et Cheng has been examined with an atomic force microscope (AFM). The results indicate that the exine substructure units containing sporopollenin in two species are similar in shape, which are granular, but slightly different in size. In Cedrus the substructure unit of pollen exine appears to be 56-99 nm long and 42-74 nm wide, while in Metasequoia it appears to be 81-118 nm long and 43-98 nm wide. It has been observed that the subunits of pollen exine in Cedrus arranged tightly to form short-rod-like or spheroidal pollen exine units, several or more than ten of which formed an island-like structure. There are various spaces among these island-like structures which are interconnected to occupy the entire pollen exine. In Metasequoia, the subunits of pollen exine also arranged tightly with a distribution tendency of cluster of 3-10, however, no obvious boundary exists among these clusters. From our results, it is concluded that there is no tendency of helical arrangement for the subunits of pollen exine in Cedrus and Metasequoia, and the results support Southworth' view that subunits of pollen exine are granular shape in lattice structure.  相似文献

 综述了基于气传花粉监测数据的研究进展,结果发现,利用花粉观测数据可获取某地的花粉概况,进而绘制具有临床价值的花粉日历。但因其不包含病例信息,故需结合过敏人群特征修正影响浓度阈值。此外,通过分析暴露于不同环境下的患病风险,证实了防治花粉症十分依赖于洁净的空气。局地观测环境及采样器的安放位置对监测结果有极大影响,但整体而言,北半球大多数区域花粉季延长、花粉浓度增加,并可归因于气候变暖所致。为预测花粉关键要素在未来的变化,4大类模型被广泛应用,并取得较好的预测结果。但对于预测效果较差的部分(花粉浓度极值、复杂地形等),最优解决方法则是结合高分辨率的花粉监测数据进行订正。但是,由于缺乏低成本的自动监测设备,当前花粉监测数据的分辨率仍然较低,由此带来了一系列的数据和技术壁垒。建议该领域应将开发低成本的自动监测设备作为近期发展的重点,并以此建立标准化的观测体系。  相似文献
