《中美物业管理比较学》讲座八 执法严格不留情 违者挨告破大财

从中美物业管理的比较来看,住宅改商用的法规,美国相对来说要严格的多,简单的多,四个字:定法执法。矛盾的双方是犯法业主与政府执法部门。     

Numerical Analysis of Plasma Initiated Polymerization

Plasma initiated polymerization is a kind of well-known radical polymerization mechanism, but it has the ＇living＇ polymerization feature and produces ultra-high molecular weight polymer. In order to explain such phenomena, we calculate the basic data of plasma initiated polymerization of methylmethacrylate （MMA） according to the principle of polymer physics and chemistry. It results in that the radical concentration ranges from 10^-12mol/L to 10^-16mol/L corresponding to the radical life in 10^4s to 10^8s, which means the radicals have a long lifetime. Moreover because of the long lifetime radicals it causes a unique feature rather than the common radical polymerization, and also shows no ＂living polymerization＂. It is noticed in experiments that there are two key factors playing important roles. One is the effective radical amount produced during the plasma discharging while the another is the diffusion factor.     

射频ICP离子源设计研究

本文介绍了射频 (RF)感应耦合等离子体 (ICP)离子源的设计研究。对RFICP的结构、离子流的引出以及离子流的均匀性、中性化和射频匹配网络进行了研究。     

一种新型自供电无线测温传感器控制系统

本文设计实现了一种新型自供电型的无线测温传感器控制系统,包括无线信号转发中继装置及自供电取能电路,主要应用在高压触头、母线和电缆头无线测温传感器系统。与常规无线测温传感器功能相比,新增功能包括:(1)针对目前常规中继装置主要采用直流5V供电,无法接入市电问题,增加AC/DC开关电源直接接入市电AC220V;(2)增加了一路无线通信模块,将从无线测温传感器采集到的数据利用无线通信的模式发送出去;(3)增加了人机接口界面;(4)增加了自供电无线测温传感器取能电路,提高了工作效率。     

《中美物业管理比较学讲座》(十七) 物业维稳 请在第一线把问题解决——谈纽约市房东房客服务机构

<正>记得我在一次讲座中提到,不要把开发商、物业服务公司、业主、业主委员会和房客之间的拆迁、群租、停车、管理费、治安、住改商、供暖等等矛盾与冲突简单地看成是物业管理问题,它的实质是社会问题。今天我想说的是,我们不要轻视这些矛盾与冲突,物业的维稳就是社会的维稳,我们的官员、街道办、居委     

《中美物业管理比较学讲座》(二十二) 纽约市廉租房小区的大问题

<正>这一讲从伦敦的骚乱讲起。8月初,英国伦敦发生了历史上最为严重的社会骚乱,警察枪杀了一名黑人,引起了伦敦的黑人、穷人、年轻人上街打砸抢,表达对政府的强烈不满。12日,英国警方出动了16000名警察,逮捕了约2200名骚乱者。英国社区与地方政府大臣皮克尔斯直言:"要严惩暴力活动参与者,如果这些人居住在政府提供的廉租     

Atomic-Oxygen Beam Source with Compact ECR Plasma

An atomic-Oxygen beam source with compact ECR plasma was succesfully investigated.the microwave was produced and transmitted in a coaxial mode,and coupled with the loop ,The plasma was produced as a higher asymmetry magnetic mirror field,and neutralized with the molybdenum target at a lower asymmetry magnetic mirror field.The magnetic field was constituted with permanent magnets.this source has a higher flux density of stom beam, a lower operating pressure ,a smaller power consumption and low-cost.When it was installed at the equipment to study the interaction of the beam with the surface,the operation was carried out very easily and with a good stability.
