Based on above results, the fermentation medium and cultivation conditions were investigated and the uniform design method was used in the optimization of fermentation medium. The techniques of fed-batch culture were also investigated in this paper, with this techniques acarbose fermentation titre increased from 1416 μg/ml to 2700 μg/ml, basically reached the level of industrial production.

The efficiency is poor and the precision is unassured in traditional jacked-pipe construction surveying. Control system in jacked-pipe construction surveying with total station is introduced, which adopts single-station and simultaneously center-line-taking and elevation control. In the process, the instrument is connected with portable computer providing corresponding software. The locus of spots is shown in time, the center line direction of pipe and the deviation of elevation is directly obtained at the same time.

Her tale is in many ways emblematic of how those customers and the designers they favor are being pushed aside for a younger, trendier and more lucrative shopper. A vibrant 55-year-old, Ms. Olsen is coming to terms with the unceremonious end of her fashion career — as the windows of the last remaining stores were papered over last month and the stock sold at discounts of 70 percent, including the hangars — at the same time she is starting over as an artist and entrepreneur.

在某些方面，她的故事及具象征性——消费者和他们所喜爱的设计师们在面对那些年轻的，追求潮流的，带来更多利润的购物者面前怎样的被忽视。55岁然而却充满活力的Olsen就这样随便的结束了她的时尚职业生涯——最后一家商店的橱窗在上个月也已经关闭，所有的库存包括仓库都已3折的低价出售——于此同时Olsen又重新成为了一个艺术家和企业家。

Primarily, the thesis assays the condition of network framework, the network was divided into three levels in terms of network management in order to establish the distributed method ,and still pointing out the intention and denotation of studying the Topology Discovery.Next, the thesis analyzes SNMP protocol minutely, including its development, principle, and the Network Management system that established on the SNMP protocol. Have analysed MIB in detail and the application way of MIB in network management .The thesis also assays the ICMP protocol, describing its working principle and the format of datagram minutely , and describing two important tools of ICMP- Ping and TraceRoute in detail. On the base of upper analysis, the thesis expounds a kind of distributed Topology Discovery project, and book it in one autonomy system. Topology Discovery was divided into two levels in terms of network management, and analyses the way of linking up between the two level. The thesis minutely assays Router-Level Topology Discovery technology basing on SNMP and Subnet-Level Topology Discovery technology basing on ARP and ICMP. According to these analyses, the thesis explores the specific methodology and the technology of XML data object which using the WinSNMP API to achieve topology discovering system on the development platform of Visual C++, and also analyses the technology of topology analysis and topology graph minutely. Moreover, the thesis assays the technology of basic firewall and Topology Discovery response strategy. Finally, the thesis analyses the underlying blind problem of the topology finding, and also analyses the reason that the blind problem produced and the way that reduced. The distributed algorithm that this paper puts forward has a certain directive significance in wireless network or other fields.
