《中华人民共和国国民经济和社会发展第十四个五年规划和2035年远景目标纲要》中将区块链作为数字经济重点产业之一,多个部门也在出台的行业领域信息化相关政策文件中,对加快区块链创新应用,推进行业数字化转型,以及促进经济社会高质量发展做出了明确部署。区块链数字资产的规范和治理,离不开对区块链技术本身的理解与分析,而从科技端观察区块链数字资产的发展机制,是其治理的创新视角和必要角度。中国区块链数字资产的治理研究,应构建科技治理和治理科技的双层制度设计,实现对区块链技术的有条件信任,加快推进区块链技术研发、建立风险评估机制以及实现区块链技术伦理作用,并引导分布式数字身份和去中心化组织的发展,明确监管边界和政府责任。

随着区块链经济的政策支持、应用的试点开放,非同质化通证产业在我国形成了良好的发展态势。从非同质化通证属性认定的全球司法判例出发,通过与加密货币在我国过往的司法裁判进行比较论证,未来我国非同质化通证属性的司法认定需结合其组织要素、平台作用以及投资者行为进行“加密资产”和“证券化”的非完全割裂的区分。同时,从加密货币到非同质化通证的司法案例中观察金融监管与金融司法的互动脉络,可以发现我国在数字金融治理过程中,金融司法进一步展现出能动效应,通过具体案件的裁判过程对监管规则进行“塑形”,以此保障金融创新与稳定安全的价值平衡。

针对直纹面面齿轮与圆柱齿轮不满足共轭关系而限制其在小传动比应用场合的情况,提出与直纹面面齿轮共轭的小齿轮及其滚齿加工方法。首先建立了直纹面面齿轮及其共轭小齿轮的齿面方程,获得共轭小齿轮相比圆柱齿轮的齿面偏差形貌;随后推导了阿基米德齿轮滚刀的齿面方程,并根据滚齿加工运动坐标系和啮合原理建立了圆柱齿轮的数学模型;在滚齿加工圆柱齿轮的运动基础上,通过增加滚刀的径向移动和工件的附加转动使滚刀切削刃逼近共轭齿面,附加运动由泰勒多项式表示,通过建立敏感矩阵方程并采用奇异值分解法迭代求解方程获得附加数控运动多项式系数,最后获得数控加工齿面;为评价直纹面面齿轮副的传动性能,进行了齿面承载接触分析,并与传统面齿轮-圆柱齿轮副进行了对比。研究结果表明:相同参数下,直纹面面齿轮副与传统面齿轮副的承载性能基本相同,完全能够代替传统面齿轮副传动;数值算例和仿真加工对该方法的验证表明,其数值算例误差不超过1μm,仿真结果误差不超过6μm,证明了该方法的可行性和准确性。

This paper studies the Least Square Method to define high-speed railway(HSR) earthquake risk and solve the problem of its emergency response mechanism. Based on the construction of a monitoring system for HSR earthquake emergency response, the technical operational procedures for HSR seismic emergency response are proposed. The quantity, scale, and location of HSR earthquake emergency response mechanism are defined, and the corresponding emergency response system is built. In particular, the earthquake emergency response system can conduct real-time continuous dynamic monitoring of seismic activity along the railway. When earthquake occurs, the intensity of the ground motion is detected by the system. When the earthquake monitoring value reaches the earthquake alarm threshold, it will send an alarm signal to the dispatch center, and the emergency power supply will be forced to cut off. The earthquake emergency response system will continue to monitor the follow-up ground motion acceleration. The system provides the operation scheduling center with a basis for train operation control to resume operation after stopping. The monitoring result of the system reduces the disaster, and the secondary disaster is caused by the earthquake. This paper improves the HSR response mechanism in detecting earthquake disasters. The result improves the ability of HSR to deal with earthquake disasters, and reduces casualties and economic and property loss caused by earthquake disasters.

Super-speed rail (SSR) is a kind of train design based on the theory of vacuum pipeline transportation, having the advantages of superspeed, high safety, low energy consumption, low noise, no vibration and no pollution. SSR may be a new generation of trains after cars,ships, trains and aeroplanes. The SSR system includes two parts, namely vacuum pipe technology and magnetic levitation *** on the definition of SSR, the present paper analyses the operation principle of SSR. According to distribution characteristicsof SSR, the evaluation index system of SSR was set up. In analysing the main characteristics of SSR, this paper builds the evaluationmodel by improved value function. The application results validate the feasibility of the new method in comprehensive evaluationfor SSR. It is consistent with the results of other methods. The result reveals that SSR is completely feasible from a theoretical pointof view and it is impossible to build SSR in a short time from the application perspective. The evaluation results can reflect the actualsituation. The comprehensive evaluation model is scientific and the process is simple。

随着区块链应用的不断深化,全球各国试图构建通证经济、数字资产、元宇宙秩序等与现实世界并存的另一社会体系。其中,作为与传统公司或合伙对应的组织体,去中心化自治组织在管理模式、数据控制、个人权益等方面体现出优势,在安全价值、效率价值、治理共识和法律可预期等方面受到价值肯定。从社会治理中的“共同体”视角,观察DAO组织的演变历程,廓清其组织要素,提出DAO组织运行过程遵循“共建共商共享”基本逻辑。我国未来对DAO组织的治理应当遵循上述逻辑,并从“与现实法律应协同而非对抗”“与传统组织并行而非取代”“共担责任但有区别”“主导但不垄断技术安全”等方面对上述逻辑加以修正。
