gva

Chapter 4 represents an implementation of GVA system .

第四章在前三章的基础上，对基于图论的脆弱性评估系统进行了设计并实现。

GVA is generally accepted as a efficient combinatorial auction mechanism .

GVA拍卖是理论上有效的多物品组合拍卖机制；

A mathematical expression was proposed for the first kind of GVA , and a new pricing method & gradually-vanishing pricing model was brought forward .

建立了第1类渐耗资产的数学表达式，提出一种新的定价方式&渐耗资产定价模型。

A GVA 5000 belt version which works with up-to-date technology and double the productivity has savings in amount of millions after 5 years .

带式GVA5000采用最先进的技术，生产率比普通机高一倍，使用5年后可节约几百万欧元。

The conception of gradually-vanishing asset ( GVA ) is presented because quite a few assets are left unused frequently while their value vanishes gradually .

针对经常出现的资产闲置而价值逐渐消逝的现象，提出渐逝资产的概念。

GVA utilized the high elevation of the villas , generous space and air circulation in their design so that the natural sea breezes would reduce the need to use air conditioning .

GVA利用别墅的高海拔地理优势，宽阔的空间以及空气的自然流通减少了空调的使用。

The result based on the comparison with other pricing methods shows that this method can decrease GVA value elapsing , raise enterprise revenue , increase consumer remnant , and further improve social welfare .

与其他定价方式实施效果进行比较的结果表明，该方法能够减少渐耗资产价值流逝，提高企业收益，增加消费者剩余，改善社会整体福利。

It is possible to transmit high electric power above 1 GVA to the load centers in downtown areas by 220 kV HTS cables so as to meet the needs for power supply by large cities .

采用高温超导电缆将有可能降低输电电压等级，可以采用220kV高温超导电缆将1GVA以上的电能输入到城市负荷中心，满足特大型城市负荷中心供电需求。

At present , there are no ideal chemical agent to prevent and control the virus disease . The cultivation of virus-free varieties is the effective way to reduce the losses caused by GVA . The virus detection is the crucial step for obtaining virus-free germplasm .

由于目前尚无理想的化学药剂来防治病毒病，因此栽培无病毒苗木是防治病毒病的有效途径，而病毒检测能够为培育和繁殖无病毒苗木提供良好的技术支撑。
