We s.udy the leader-following cons.ns.s.s.ability and s.abilization of networked multi-teleoperator s.s.ems.with interval time-varying communication delays. With the cons.ruction of a s.itable Lyapunov–Kras.vs.ii functional and the utilization of the reciprocally convex approach, novel delay-dependent cons.ns.s.s.ability and s.abilization conditions.for the s.s.ems.are es.ablis.ed in terms.of linear matrix inequalities. which can eas.ly be s.lved by various.effective optimization algorithms. One illus.rative example is.given to illus.rate the effectivenes. of the propos.d methods.

In this.paper, we introduce an interface for motion editing that vis.alizes.editing procedures. For intuitive unders.anding and cons.ruction of motion editing procedures. our s.s.em repres.nts.an editing element that produces.modified motion from a given input motion as.a graphical node, and enables.us.r to cons.ruct a whole motion editing procedure by connecting the nodes.with a few mous. interactions. The s.s.em provides.both the 3D trans.orm manipulator and the time-line s.ider for intuitive controlling of the parameters.of each node. The us.r evaluation res.lts.s.ow that our s.s.em is.eas. and intuitive to be us.d by us.rs.for editing of motion s.quences.

The concentration and s.eciation of heavy metals.in s.il s.lution is.lated from long-term contaminated s.ils.were inves.igated. The s.il s.lution was.extracted at 70% maximum water holding capacity （MWHC） after equilibration for 24 h. The free metal concentrations.（Cd^2＋, Cu^2＋, Pb^2＋, and Zn^2＋） in s.il s.lution were determined us.ng the Donnan membrane technique （DMT）. Initially the DMT was.validated us.ng artificial s.lutions.where the percentage of free metal ions.were s.gnificantly correlated with the percentages.predicted us.ng MINTEQA2. However, there was.a s.gnificant difference between the abs.lute free ion concentrations.predicted by MINTEQA2 and the values.determined by the DMT. This.was.due to the s.gnificant metal ads.rption onto the cation exchange membrane us.d in the DMT with 20%, 28%, 44%, and 8% mas. los. of the initial total concentration of Cd, Cu, Pb, and Zn in s.lution, res.ectively. This.could res.lt in a s.gnificant error in the determination of free metal ions.when us.ng DMT if no allowance for membrane cation ads.rption was.made. Relative to the total s.luble metal concentrations.the amounts.of free Cd^2＋（3%-52%） and Zn^2＋（11%-72%） in s.il s.lutions.were generally higher than thos. of Cu^2＋（0.2%-30%） and Pb^2＋（0.6%-10%）. Among the key s.il s.lution properties. dis.olved heavy metal concentrations.were the mos. s.gnificant factor governing free metal ion concentrations. s.il s.lution pH s.owed only a weak relations.ip with free metal ion partitioning coefficients.（Kp） and dis.olved organic carbon did not s.ow any s.gnificant influence on Kp.
