In this paper, we discuss quantum uncertainty relations of quantum coherence through a different method from Ref. [52]. Some lower bounds with parameters and their minimal bounds are obtained. Moreover, we find that for two pairs of measurement bases with the same maximum overlap, quantum uncertainty relations and lower bounds with parameters are different, but the minimal bounds are the same. In addition, we discuss the dynamics of quantum uncertainty relations of quantum coherence and their lower bounds under the amplitude damping channel（ADC）. We find that the ADC will change the uncertainty relations and their lower bounds, and their tendencies depend on the initial state.

从对人格权的源流和发展的梳理来看,人格权最早脱胎于宪法的人权理论,故而人格权自诞生日起便具有浓厚的宪法权利特色,但人格权又同时具有鲜明的私权属性,在民事领域蓬勃发展。从宪法与民法的关系来看人格权的权属问题,既要警惕民法学者所倡导的民法与宪法的截然二分,又要防范宪法学者对民法与宪法界限的过度模糊。人格权同属于宪法与民法,且同时在各自领域独立发挥作用,这是公私法人格权保护的基本分野。《民法典》落成之后,我国人格权保护进入了新时代,自成体系的民法典在分野的视域下便可开放式地发展吸纳不同类型的人格权资源,并以此反哺于宪法。随着法治进程的不断向前,宪法开始私法化、公私法不断交融,截然的公私二分情形已经不复存在,民事权利不断展现基本权利倡导的价值,宪法的客观价值秩序不断发挥作用并以基本权利价值统率公私部门法对人格权的协调保护。

The aim of this study is to evaluate the current state of rural area development at the county level in the eastern coastal China. An evaluation index system including 18 factors was developed, and a rural development index (RDI) was constructed to evaluate rural development state in 2000, 2004, and 2008. The quantitative evaluation indicated the following results. 1) This study derived four dominating components by means of principal component analysis, which can explain 78.2% of the total information, namely agricultural production input, the basic condition of agriculture, the comparative effectiveness of grain production, and the household′s own basic conditions. 2) Since the turn of the new millennium, the rural area in the eastern coastal China has experienced a rapid development in general. Well developed, developed, moderately developed and undeveloped rural areas respectively occupied 29.32%, 22.33%, 21.91%, and 10.51% in 2008. 3) The countryside had maintained a sound momentum of developing trend between 2000 and 2008, while the rural development in the eastern coastal China lacked sustainability. And 4) industrialization, urbanization, original economic basis, and location are four major driving forces of the disparity of rural area development in the eastern coastal China. Given these results, the strategies and policies for the improvement of each rural group were put forward.

方证相应是指在治疗疾病时,一个方子对应一个证型,既包含方药,也包含相应的证,既有理,亦有法。对于精浊的治疗,先弄清疾病证候,再选择相应的方剂。以“疮疡”指导精浊的论治,必须紧紧抓住其与疮疡在病因病机上的相似性。从中医理论方面分析,二者的基本病机变化有气血瘀阻、壅滞不通、化热成脓的相似性。以方证相应理论为指导,对精浊各阶段的病因病机进行相关探究,论述精浊不同证型的方子选用,为今后治疗精浊提供一定的研究思路。

This study has demonstrated an interesting amplification effect of magnetic field (MF) on the hydroxylamine (HA)-promoted zero valent iron (ZVI)/H_(2)O_(2) Fenton-like system. Sulfamethoxazole (SMX) could be efficiently degraded at near neutral pH. Conditional parameters affecting the SMX degradation in the ZVI/H_(2)O_(2)/HA/MF system, e.g., pH and the dosages of ZVI, HA and H_(2)O_(2), were investigated. Unlike the acid-favorable ZVI/H_(2)O_(2) and ZVI/H_(2)O_(2)/HA systems, the MF-assisted system exhibited good performances even at pH up to 6.0 and highest degradation rate at pH of 5.0. ^(·)OH was still identified as the responsible oxidant. A mechanism involving the MF-enhanced heterogeneous-homogeneous iron cycle was proposed in the near-neutral ZVI/H_(2)O_(2)/HA system. Without MF, HA-induced reductive dissolution of the surface iron oxides occurred and thus leaded to homogeneous Fenton reactions. After the introduction of MF, the gradient magnetic field formed on the ZVI particles would induce the generation of concentration cells of Fe(II) and local corrosion of iron. Large amounts of aqueous and bounded Fe(II) catalyzed H_(2)O_(2) to efficiently produce ^(·)OH, while HA maintained the surface and bulk cycles of Fe(II)/Fe(III). The result of study is expected to provide a green, energy-free method in improving the effectiveness of ZVI-based Fenton-like technologies at weak-acidic circumstances.
