摘要：本发明提供了一种荧光分析的标准光源，该光源为具有至少一个色心的材料。由于色心具有各种环境下的光稳定性、化学惰性、生物兼容性以及不易擦除；发光强度为弱光，且可以通过色心数或色心浓度的调节达到从单个色心的单光子源到较强发光强度的较大范围的调节，便于对各种弱发光物体进行荧光强度的定量标定。因此，本申请以具有色心的材料作为荧光分析的标准光源，避免了在传统荧光分析中用于标定的标准光源发光不稳定，随时间衰减，对环境要求高等问题。本发明利用含有NV色心的纳米金刚石和人工制备的含有NV色心的金刚石块体两种材料为例，给出本

摘要：本发明涉及基于可信性评估的区块链共识方法。本方法采用基于信任值的加权投票共识，按照信任值排名动态随机组成共识组。每个共识组的成员都有与其信任值成正比的投票权重，而信任值由长时间累计的综合表现决定。所以，只有诚实的节点，表现长时间的正常并且有规律，才可能成为共识组的一员。共识组中会有一矿工被随机选中成为领导者，领导者可以产生微块对交易进行打包，其它节点对微块进行共识，一轮工作结束。本方法有三大改进：第一，发明一种新型的领导者和共识组的创建方法，保证选择的随机性和公平行。第二，基于长时间累计的综合表现所创建的信任值计算方式。第三，创造了一种基于改进的raft的共识算法，可以扩大吞吐量。
