量子区块链：融合量子信息技术的区块链能否抵御量子霸权？

智能科学与技术学报, 2019
区块链的广泛应用使越来越多的学者聚焦到安全加密这一重大问题上。然而，随着电子计算机技术的飞速发展，远超传统计算速度和数据处理容量的量子计算机已经逐步从理论走向实践，它的极大算力将给区块链的链内安全带来巨大和根本性的挑战。介绍了量子信息的两大核心应用，分析了量子霸权对区块链现行的共识方式和加密算法的破解方式。同时，针对目前区块链的漏洞，提出量子区块链以防止量子计算带来的攻击威胁，并阐述了量子通信技术的原理与应用方法，举例说明了量子区块链的安全性与可行性。最后，对目前量子计算存在的几大技术挑战进行了分析。

不同水氮管理对日光温室番茄产量及土壤无机氮的影响

Shuitu Baochi Xuebao, 2008
以传统水氮管理为对照,分别采用氮素实时监控技术对保护地番茄主要生育期进行氮素追施优化管理,同时结合小管出流的灌溉方式及夏季休闲季添加小麦秸秆-氰氨化钙的优化水氮管理处理并根据课题组同一地区多年的番茄氮素优化管理经验得出的推荐水氮管理处理,即将氮素追施量定为N 300 kg/hm2,在番茄第一、三、五穗果实膨大期各追施N100 kg/hm2,比较研究了不同水氮管理措施对保护地番茄产量及土壤无机氮的影响。结果表明:与传统水氮管理相比,在保证番茄产量的前提下,优化水氮管理和推荐水氮管理两季番茄分别减少了63 ...
