The adaptor is a must for numerous computer peripherals. As an important computer exporter worldwide, the dc power supply industry is bloomy in Taiwan. In today's dc power supply market, the switch power supply has replaced the linear adaptor as main stream in the industry globally for its compact size. However, SPS has a serious problem of high frequency electromagnetic interference and causes harmonic feedback for the AC power source compared with linear adaptor. The energy consumption is also worse for SPS than linear adaptor.

摘要整流器是许多电脑周边设备不可或缺的电能，而台湾又是电脑及周边产品出口大宗国，因此电源供应器产业澎勃发展是必然的，其中轻薄短小及输出稳定之交换式电源供应器(Switch Power Supply：SPS)，已取代传统线性整流器的地位，成为外销主力并取得世界龙头地位，然SPS有严重的高频电磁干扰问题(150KHz~300MHz)，在交流电源侧产生的谐波含量，也较线性整流器来得严重，为一耗能产品。

Bulter, Ammons, and Sokol argue that the model of new product supply chain of the past neglects the condition which new products may not survive. Thus they developed a new product supply chain model to enable new products to launch the market and grow to maturity as well as decide when to purchase new supply chain facilities and equipments.

学者Butler， Ammons， and Sokol认为过去新产品供应链模式忽略了新产品将有可能无法存活下来的情形，因此发展一套新产品供应链模式，使新产品供应链能够顺利从上市成长到成熟阶段，并利用此模式决定新设施、新机器购入的时机。

Copper content and accumulation in shoots of both two Elsholtzia species decreased with increasing Zn regardless of Cu supply. However, Zn concentration in E. splendens were increased by Cu supply at low or high Cu level, and in E. argyi Zn contents were also increased by Cu supply at 0.5 and 50μmol L〓.

研究结果表明，50μmolL〓的Cu有利于海州香薷根系的生长，但却明显抑制紫花香薷地上部分的干物质产量，Zn处理浓度直到200μmol L〓也未见两种香薷的干物质产量的下降。

The supply chain coordination with sales effort effects is explored. This work designs a contract to coordinate the supply chain in case of observable sales effort; it proves that the usual contracts can never coordinate the supply chain, but a modified scheme can improve the performance of the whole system in term of inobservable sales effort.

分析了进取型供需链的协调问题，如果促销行为是相互可观测的，设计了一种特殊合同策略来协调该系统，如果促销行为相互不可观测，则证明了常见合同策略无法完全使系统达到协调，但适当的设计可以改善系统性能。

Enterprise supply chain to include many pieces of logistics with many node, complicated system to step region of information flow, the complexity make enterprise supply chain have heavy risk very, enterprise supply chain enterprise interdepend, influence each other, any link will all be involved and supplied the chain entirely while going wrong.

企业供应链是包含多条物流和信息流的多节点、跨地域的复杂系统，这种复杂性使得企业供应链存在很大的风险，企业供应链企业相互依赖、相互影响，任何一个环节出现问题都会波及整个供应链。
