ECG is an important method in clinical heart disease diagnosis. The storing of lots of ECG and other corresponding materials in information management system has great value to medical researcher for their reference and research. Embedding the ECG information management system to virtual ECG instrument is not only enhanced the operating value but also increased the functions to virtual ECG instrument. The model of relation database and ActiveX Data Object (ADO) of VC++6.0 is used in the system. The key functions of Storing,Query,Deleting and core modules are introduced. 相似文献

树高的精准测量是森林资源经营和管理的一项基础工作,也是评价立地质量和林木生长状况的重要依据。实验中利用测高器、罗盘仪、经纬仪和全站仪等仪器测定了7个不同树种的树高,阐述了其测量的原理与过程,并构建了树高精准化测量的模型。根据30组不同树种的树高测量数据进行对比和分析,得出树高自动精准测量的结果:全站仪的精度最高,其次是经纬仪和罗盘仪,最后是测高器。采用相同的仪器测量不同树种的树高,其精度也不同。树干笔直、树冠简单的树种精度较高;针叶树种也比阔叶树种精度高。构建的树高测量模型,为实现林业调查的自动化和精准化提供了理论依据。 相似文献

秸秆利用途径的分析比较 总被引:15,自引:1,他引:14
作为农业大国,中国的秸秆年产量在7 亿t 左右。以廉价的农业废弃物秸秆作为原料转变成能源是一项非常有价值的研究。文章从秸秆制备乙醇、甲烷-甲醇及气化、液化制备柴油几个方向进行讨论。用秸秆等废弃物制造能源引起了广泛的关注,不仅降低了成本,而且减轻了处理秸秆所造成的环境问题。通过对这些方向的原理、操作条件、设备、经济性等进行比较,进而得出秸秆转变能源途径中最有利的发展方向。结果表明,利用秸秆生产燃料乙醇,每t 秸秆产生的热量最多(18900 MJ),且产生的价值可观,纤维素乙醇的发展潜力最大。秸秆制乙醇的利用率以及经济效益较高,是一种较好的利用秸秆能源化的途径。 相似文献

On Light and Simplified Cotton Cultivation 总被引:6,自引:5,他引:1
The main contents of light and simplified cultivation (LSC) of cotton are discussed, and the LSC development is prospected in the paper. Light and simplified cultivation of cotton refers to the simplification and minimization of field management and operations, as well as the integration of agronomic technologies and agricultural machinery or good cotton variety to reduce production costs and labor intensity during cotton farming and cultivation, and to realize sustainable production. LSC is an important supporting technology for China's cotton production from the traditional labor intensive to the light and cost-saving, which is fully based on the national conditions of China. The new cultivation technology system was established after the innovation and transformation of traditional cotton cultivation technology. The LSC technology system mainly includes precision mono-seeding, simplified pruning or non-pruning technique, one-time fertilization technology or fertigation management technology, and optimization of boll setting through regulation of fruiting distribution and grouped harvesting technology. From the perspective of the future, we should further optimize the planting pattern, improve the key cultivation techniques of LSC, develop new material and equipment, promote the high fusion of agronomic technology and material equipment, and provide more powerful theoretical and technical support for LSC. Improved LSC will play more important roles in supporting the sustainable development of cotton production in China. 相似文献
