查询词典 mobility

The new rT joint not only has two rotation axes that intersect at right angle,but also has another rotational degree of freedom which can be used to modify the assembly of other joints.This can change the mobility of the parallel mechanisms that assembled with the new rT joints and leads to two types of metamorphic paralllel mechanisms:In the first type,the mechanism changes its topology by turning the new rT joints in all limbs into different configurations which reconfigures the constraints within the limbs or the assembly of all the limb constraints.This change of mobility is completed by two cases.One is illustrated by a 3PS and a 3C parallel mechanism,by altering the rT joint into different configurations there will produce or reduce local degrees of freedom and thus change the constraits to the moving platform.This qualifies the 3PS and 3C to have variable mobility from 3 through to 6 and from 1 through to 6 respectively.

该铰链除了一般Hooke铰的两个轴线互相垂直相交的旋转自由度外，还增加了一个可以调节该两个轴线之一的姿态的一个旋转自由度，通过此自由度调节该rT铰到不同的装配构型，可以改变用其装配的并联机构的自由度，由此产生两类新型的并联变胞机构：一类是机构的各个支链中都有rT铰，该铰链的不同构型可以改变各支链对运动平台的约束或整个支链组的组合形式而改变机构的自由度状态，3PS和3C属于前者，通过调节rT铰到不同构型可以使其支链产生或消失局部自由度，从而减少或增加支链对运动平台的约束，使得并联变胞机构3PS和3C分别具有自由度从3变到6和从1变到6的能力；3P属于改变支链组组合形式的机构，其rT铰的不同构型将改变整个支链组的几何约束组合，使得并联变胞机构3P可以有三转动、三平动或三平移(来源：ABCded9de论文网www.abclunwen.com)一转动的自由度形式。

From the detailed simulation results and analysis,for the emulational frame based on minimum zone set,the route discovery mechanism of DSR is independent of nodes mobility,every once,the source node acquires a route to a target node which its relative position is alterant,the routing time is steady but not be effected by nodes mobility,the conclusions are obvious helpful for reducing route tip and increasing routing efficiency.

通过对选取总路由流量，路由平均跳数、平均路由发现时间的实验数据分析发现，对于基于最小区域集的仿真框架，DSR的路由发现机制并不受节点移动性的影响，每次源节点获得一条到达相对位置已改变目的节点的新的路由的时间并不受节点的移动性影响而趋于稳定，可明显减少路由跳数，增加路由计算效率。

Meanwhile, the concentration of Pb,Zn and other heavy metals is rather high in the oxidation zone and decreasesdownward to levels that are unbelievably low for Pb-Zn mine tailings. Theseobservations suggest that heavy metals should be re-immobilized by secondaryminerals, rather than primary minerals, in the oxidation zone, and could be leachedout from suboxic environment due to low rate oxidative dissolution which preventsthe precipitation of secondary minerals in significant amount. Thus, cover scenarioswhich establish a suboxic environment beneath the cover layer might not always beeffective in preventing heavy metal release from mine tailings.Sequential extraction studies indicate that, in addition to heavy metal leaching,oxidation of the mine tailings increased the mobility of residual Zn, and Cu, while Pb remains immobile due to the formation of anglesite (PbSO4). Using the seven-step extraction technique developed by Dold (J. Geochem. Explor., 2003, 80: 55-68), galena dissolves in significant amount at step 2 most probably due to the strong complexing of Pb2+ by acetate, while other metal sulfides dissolve at step 6, which suggest that this extraction technique could not be used to evaluate the mobility of lead in natural environment

重金属含量均低于新鲜尾矿，但以硬化层中的含量最高(Pb、Zn含量分别为0.47%和0.93%)，往下大幅度降低，表明尾矿风化过程中形成的次生矿物对Pb、Zn等重金属元素有较强的固定作用，而次氧化带的淋溶作用造成了金属元素的大量流失；(4)与新鲜尾矿相比，硬化层中铅的可迁移性大大降低，硬化层之下尾矿样品中铅的可迁移性也不同程度降低，这是由于硫化物氧化产生的硫酸根与尾矿中的铅反应形成铅矾(PbSO_4)的缘故；(5)氧化作用使尾矿中的zn、Cu等重金属的可迁移性不同程度地增大，其中对锌的可迁移性影响最大，铜的可迁移性与铁比较相似，铅则容易与硫化物氧化形成的SO_4~(2-)反应形成铅矾(PbSO_4)；(6)为了减少尾矿污染和修复矿山环境，人们提出了各种不同的尾矿覆盖方案，本文的研究结果表明，这些方法不一定能够有效地阻滞污染元素的迁移。
