Abstract Previous studies have dealt with Cr and its alloy films that exhibit promising characteristics as surface modification layers for antiwear, anticorrosive, decorative applications. However, the effect of Ti alloying on structure mechanical properties has not been studied. This work aimed to Cr-Ti in Cr-rich side. To this end, pure Cr, Cr-6 at.% Ti, Cr-11 Cr-16 Cr-21 were prepared by magnetron sputtering, evaluated. The results indicated all exhibited a Cr-based growth body-centered...
Abstract The brittleness and relatively poor adhesion properties of CrN materials have been extensively addressed by developing Ni/CrN composites with a separate Ni phase. However, conditions at the interfaces, which are key features leading to enhanced toughness, remain poorly understood. present work addresses this issue investigating effect interface orientation on strength fracture toughness interfaces using first-principles calculations. To end, we build seven models, including...
89 Au geochemical anomalies are delineated by using 1/200000 regional exploration data. By researching characteristics and the relationship with geological background, author points out that: main factors causing high background of Gaixian Dashiqiao formation Liaohe group, intrusions Mesozoic intermediate-acid intrusive rocks. The elements combination types typical determined factorial analysis,cluster analysis other mathematical methods association in anomalies:the composite anomaly Baiyun...
Vehicle Routing Problem (VRP) is one of critical problems in modern logistics service. In order to overcome the shortcomings basic Ant Colony Optimization (ACO) algorithm, which has long searching time and easily jumps into local optimal solution, a hybrid behavior ACO algorithm presented for solving VRP problem. A series rules ants' behaviors are defined. The simulation results show that above approach reasonable efficient.
By study the development situation of blast furnace smelting in china and operation system technology, combined with production conditions JISC BF, based on a large number data, comparison analysis test BF technology was did. Through continuously optimization practice, relatively suitable at present explored, which could reduce coke ratio into while increasing coal injection making great economic effect.
威海位于苏鲁造山带最北端,出露片麻岩和榴辉岩等多类超高压岩石,是研究大陆俯冲带变质、深熔和熔体效应的理想靶区。基于详细野外观察,本文对该区的一套钙硅酸盐岩、伟晶岩脉和寄主片麻岩进行了岩相学、地球化学和锆石年代学等研究,旨在深入探究超高压变质岩的多期熔融及与之伴随的地质过程。阴极发光显示,三类岩石中的锆石整体具有核-边结构,继承核年龄为859±20Ma~272±6Ma,与苏鲁变质岩内大多残余岩浆锆石的年龄一致。新生锆石共记录了约237±4Ma、224±7Ma~218±2Ma和177±5Ma~166±3Ma等三组年龄。结合不同微区的稀土元素特征,本文认为,237±4Ma记录了峰期变质时代,而224±7Ma~218±2Ma和177±5Ma~166±3Ma年龄的锆石呈现典型的深熔锆石特征,分别代表俯冲陆壳折返至高压榴辉岩相和加厚地壳初始伸展阶段的部分熔融年代。伟晶岩与片麻岩中继承锆石的Hf同位素组成不同,表明形成伟晶岩的熔体并非寄主岩石直接熔融而来。此外,钙硅酸盐岩及其内部的单斜辉石具有极低的Cr、Ni等相容元素含量和负Eu异常特征,且均显示大离子亲石元素富集、高场强元素亏损的特点。并且...
The present study attempts to explore the differences in nicotine dependence and delay discounting between traditional cigarette e-cigarette users.

摘要: 该文提出了ASON网络中一种基于折回点重路由的折回机制，当连接发生折回时，该机制通过折回点对连接进行重路由，从而省去了折回消息发送的过程。为了实现该机制，扩展了信令消息及处理流程。搭建了15个节点的试验平台，采用了RSVP-TE、OSPF-TE及LMP等协议来实现ASON网络的控制平面。试验数据显示该机制与传统的折回机制相比较，不但节省了信令通信网(SCN)的带宽，而且节省了连接的最终建立时间。 关键词: ASON / 折回 重路由
Health monitoring devices are critical for the safe and reliable operation of water supply systems, but their chemical batteries easily depleted. Thus, this paper developed a micro-vertical axis turbine that converts part head into electrical energy supplies power device. The performance four groups micro-turbines was investigated in detail through experimental testing. Different from our previous study, entire curves at different rotation speeds flow velocities were obtained order to...
Abstract The carbonate rocks were collected from the Qum Formation in outcrop of northern Garmsar Area, Iran.
