After electrophorised on 1 % agarose gel, the pcr production was purified with agarose gel dna extraction kit. the segment was ligated with vector pmd18 - t and then was tranformed into the competent cell of dh5 a. a construction mstnd - pmd18t was generated by inserting the sequence of 254bp into pmd18 - t vector and selecting the sense clones. positive clone was identified by three ways : endonuclease digestion, pcr and sequencing. the result showed that the cloned sequence coincides with the designed sequence. this construction was digested with nco i and xho i and ligated the pet28a ( + ) vector digested with the same enzymes using dna ligation kit. the production of ligation reaction was transformed into the competent cell of bl21 ( de3 ). after 12 - 16 hours of culture, several colnes appeared on the plate. some positive clones were selected to extract their plasmid. these plasmids were digested by nco i and xho i and indentified by pcr. a contraction, mstnd - pet28a was generated. the result showed that the cloned sequence coincides with the designed sequence
F _ 1長38bp ， r _ 1長36bp ，其它片段均40bp長， f _ 1和r _ 1片段兩端分別加上限制性內切酶nco和xho的識別位點序列。用成對單鏈片段進行延伸反應，然後用其他單鏈片段作為引物，進行pcr擴增，用dna快速純化回收試劑盒回收所得254bppcr產物，與pmd18 - t載體連接、轉化dh _ 5 。受體菌感受態細胞，利用藍白斑遺傳學篩選法篩選陽性克隆，提取其質粒，採用nco和xho雙酶切鑒定，獲得了254bp的片段；用pmd18 - t載體上的特異引物rv - m和m13 - 47進行pcr鑒定，獲得300bp的片段。 -
Then, using the qulititve methods, the marketing management operation is analyzed and researched comprehensively, the main reasons of bad sales, which are unreasonable design, higher price and single promotion means, are found out. using ism ( interpretive structure model ) method, the key factors influenced the project ' s marketing, which are product, price and promotion, are analyzed. according to the characteristics of office blocks, segment variants of the target market are defined ; the target customers of the project are selected based on the statistical primary futures of target customers
接著運用定性分析的方法，對西安財富中心寫字樓項目營銷管理運行狀況進行了全面的分析和研究，找出了本項目銷售不暢的主要原因在於產品設計不合理、產品定價過高、市場推廣手段單一等三方面；運用解釋結構模型（ ism ）分析法，對影響西安財富中心寫字樓項目營銷的關鍵因素進行了分析，確定了該項目營銷的關鍵因素在於產品、價格、市場推廣三方面；根據寫字樓產品的特點，明確了目標市場的細分變量，統計出目標客戶的基本特徵，確定了西安財富中心寫字樓項目的目標客戶。 -
This paper introduces the realization scheme and key technology of 2 ~ 12ghz ultra - wideband microwave frequency synthesizer. it adopts dds + pll frequency synthesizer scheme to realize low end frequency 2 ~ 4ghz output, then through segment amplifying multiplying chain realize from 2 ~ 4ghz expand to 2 ~ 12ghz, and the output frequency is selected by microwave switch
採用dds + pll的混合頻率合成方案實現低端頻率2 ~ 4ghz的輸出，再通過分段放大倍頻鏈路實現從2 ~ 4ghz到2 ~ 12ghz的擴頻，並由微波開關控制選頻輸出。 -
The text compares experiment data with the selected theory direction fig and modifies the equal value and standard difference of each segment i n the se i ected wave w i dth d i r ect i on f i g by us i ng the re i at i ve i y between the statistical equal value and standard difference, then makes use of the controls the correlation time to real ize the signal undulate
通過實驗數據與選定的理論方向圖的對比分析，利用統計出的均值和標準差的相對量，對給定波束寬度的方向圖每段的均值和標準差進行修正。然後利用相關特性，通過控制相關時間，以達到能夠控制信號起伏的目的。
