被继承人死亡之后留下的遗产若不能完全清偿全部债务,则必须按照一定顺序对各类债务进行清偿,其顺序的确定除应遵循民商法基本原理之外,还应当坚持"从身份到契约"的法的演变发展轨迹。在现行立法未明确规定的情况下,我们需要打破债的平等性,从公平和效益两个维度出发,在回归社会本位理念的基础上建立一套既有利于债权人和社会公共利益,又能保障继承人等相关利害关系人基本人权的遗产债务清偿顺序衡平机制。

The mutton industry plays a pivotal role in the animal husbandry industry of Xinjiang Uygur Autonomous Region. To better monitor the volatility movement and risk warning of mutton price, the fluctuation characteristics of mutton prices and the future trend of prices are analyzed systematically. On the one hand, the Hodrick Prescott(HP) filter method is used to analyze the longterm trends and cyclical characteristics of mutton prices in Xinjiang and explored the spatial evolution characteristics of mutton price fluctuations in various regions of Xinjiang. On the other hand, the Threshold Auto-Regressive(TAR) model is used to analyze the linkage relationship between mutton prices and the prices of other livestock products. The empirical results show that(1) the overall volatility of mutton price in Xinjiang is high, showing a trend of rising first, then falling and then rising from the temporal perspective.(2) At the regional level, the price in the south is higher than that of the north, showing a decreasing trend from south to north on the whole from the spatial viewpoint.(3) From the linkage relationship perspective, mutton and beef are complementary in the short term,but they are substitutes each other in the long term. This paper explores the characteristics of mutton price fluctuations in Xinjiang from the single time series of mutton prices and the linkage with other livestock products, which provides a reliable basis for the monitoring and risk warning of mutton price fluctuation.

南京地铁6号线应天东街站~中和桥站区间采用盾构法穿越秦淮河,存在盾构磨桩、穿越河道和在上软下硬土层中掘进等多重风险,因此,对掘进速度、注浆参数、土仓压力等有较高要求。根据类似地层的施工经验,对堤岸加固措施进行对比分析后,南岸采取钻孔灌注桩加高压旋喷桩的加固方案,在此基础上,对盾构施工参数进行优化,并制定了盾构掘进姿态控制、注浆控制、渣土改良等技术措施。按照设定的施工参数,对隧道穿越堤岸桩基和河道进行了数值模拟分析,并结合施工后的监测数据表明:现有的施工参数及措施是合理的,盾构施工对河道及堤岸影响较小,盾构机可以安全穿越秦淮河。
