Firstly, to state that the study of scm optimization calls, i present the main problems when our home enterprises put scm in practice and the lack of present theoretics. then i divided all of the means of scm optimization into two classes - enterprise management methods and information technology methods, and i discussed every information technology method in detail : enterprise management methods i discussed cover mapping out manipulable plans, strengthening core ability and improving scale economic benefit, controlling sc ' s risk, and making use of the third party ' s logistics. in chapter 4 i discuss information technique methods in detail, which cover optimizing r & d of erp and scp, edi techniques, internet information technology, the other logistics techniques, advance planning system, and network technology
最後詳細論述了優化供應鏈管理的各種企業管理方式，主要包括有：制定可行的優化實施計劃、加強企業核心能力提高企業規模經濟效益、控制供應鏈風險的措施、合理利用第三方物流等幾種方式，第四章主要論述了優化供應鏈管理的信息技術手段，有: erp和scp軟體開發的優化、使用edi技術優化供應籩管理、基於internet的供應鏈管理信息技術支撐體系、其它物流技術手段、高級計劃排程系統以及網路技術方案等。 -
Because of modis predominant space and spectral differentiate rate, it ’ s has been broadly applied to various field, in the aspect of snow monitoring, modis has been successfully using a normalized difference snow index ( ndsi ) to provide global automated binary maps of snow cover. the ndsi is a spectral ratio that takes advantage of the spectral difference of snow in short - wave infrared and visible spectral bands, although it has higher precision, it can only discern one pixel to snow or other features, can not satisfy accurate drainage basin snow cover mapping and snow parameter extracting
Modis數據因其優越的空間解析度、波譜解析度，已被廣泛的運用於各個領域，在積雪監測方面，已成功地運用歸一化差分雪蓋指數（ ndsi ）製作每天的全球雪蓋分布圖， ndsi是基於雪對可見光與近紅外波段的反射特性和反射差相對大小的一種測量方法，然而它只能將一個像元辨別為積雪或非積雪，滿足不了高精度應用要求。 -
In the research of the theory of generalized metric spaces, the method of mapping and covering is a very important tool, especially the point - countable covers play a more important role. for example, the concept of paracompactness was introduced by way of using a class of special point - countable cover by the famous french mathematician dieudonne in 1944
在廣義度量空間理論研究中，映射和覆蓋的方法是一種非常重要的工具，特別是點可數覆蓋起著舉足輕重的作用，例如， 1944年法國數學大師dieudonn引進的仿緊性概念使用的就是一類特殊的點可數覆蓋。 -
