The hwtx - i gene was chemically synthesized according to its known cdna sequence, the gene was inserted into vector ppic9k which contained aoxj promotor and the sequence of a secreting signal peptide - a - factor, the cloning ppic9k / hwtx - i was constructed and confirmed by two - step pcr and dna sequence analysis, then it was transformed into host strain gs115, a his + muts cell line was screened and multicopy transformants were screened by various g418 concentrations, the multicopy transformant was named gh1. gh1 was cultivated in flasks. after 6 days of induction by 0. 5 % methanol, the supernatant was checked by 16. 5 % tricine - sds page, which showed there was a band in the position of 3. 5 - 6. 1kd, then it was isolated and desalted by ultrofiltration followed by ion exchange of cm column, after reverse phase hplc of ci8 and vacuum drying, the purified rhwtx - 1 was obtained which was proved to be correct recombinant hwtx - i by tricine sds - page, maldi - tof mass spectrometry, amino acid composition analysis, the n - terminal amino acid sequence and its biological activity, the final field of the purified rhwtx - i was about 80mg / l, accounting for 23. 6 % of it total secretory proteins
將帶有hwtx -基因的ppic9k經blgii線性化后，轉化酵母宿主菌gs115原生質體后經篩選陽性克隆並經表型鑒定為his ~ + mut ~ s酵母菌，進一步用遺傳毒素g418篩選多拷貝的轉化菌株，命名為gh1 ；將gh1甲醇酵母菌用0 . 5的甲醇誘導表達，發酵上清經90飽和度的（ nh _ 4 ） _ 2so _ 4沉澱， yw - 3 （ mwc03000 ）的超濾膜超濾，再經cm陽離子交換， c _ （ 18 ）反相hplc純化得到分子量為4kd左右的組分，其中4289 . 05的組分經質譜鑒定，氨基酸組成分析和序列測定為正確的表達產物，生物學活性表明其活性為天然毒素活性70 % ，表達量為80mg / l 。 -
Then, combined with the mechanism of vacuum preloading and based on the layer method, settlement calculation of vacuum preloading was analyzed. the study shows that the vacuum degree under membrane equivalent load method does not accord with the mechanism of vacuum preloading. based on the layer method, vacuum degree difference method and effective stress method are presented. the results show that the final settlement calculated by the vacuum degree difference method is more close to the observation results
然後，結合真空預壓的機理，基於分層總和法的思想，對真空預壓沉降計算方法進行研究：指出用現有的膜下真空度等效荷載法進行沉降計算不符合真空預壓機理；提出了符合真空預壓機理的真空度差值法與有效應力法，前者所推算的最終沉降量較接近實測推算結果，後者與實際結果存在一定差距。 -
Based on actual data, emphasizing particularly on the course of consolidation and deformation of preloading method combing vacuum with stack - load, the paper illustrates the mechanism of deformation of pre loading method combing vacuum with stack - load from consolidation and final effect, and calculates final settlement by delamination summation - method and hyperbola method, presenting relative parameters used for designing and execution control
摘要以實際監測資料為依據，對真空聯合堆載預壓法的固結過程和變形過程進行了分析，從固結和最終效果這兩個基本問題上闡述了真空聯合堆載預壓法的變形機理，採用分層總和法和雙曲線法推算最終沉降量，並給出了相關的設計和施工控制參數。 -
The influence of various factors, including lowest pressure of the vacuum chamber, water content and size of the sample in three states of solid, lidquid or syrup, on cooling rate and on final sample temperature in self - freezing by vacuum pumping, was studied
摘要以液態、漿態和固態三種不同類型的物料為對象，通過大量實驗研究了真空室壓力、物料含水量和尺寸對抽真空自凍結的降溫速率和對凍結最終溫度的影響規律。 -
Finally, this paper detailedly introduces the application of preloading method combining with vacuum stack - load in the practice of a freeway project. three sorts of experience calculation method of final settlement which based on the settlement data measured in - site are contrastively analysed, and points out the hyperbola method be recommended for settlement predicted because it accord with the actual instance of guangdong pearl river delta area, and bring up the range of settlement correcting coefficient corresponds to the characteristic of the region
最後，本文結合某高速公路工程實踐，詳細介紹了真空聯合堆載法在高速公路上的應用，並利用實測沉降曲線對三種預估最終沉降量的經驗方法進行了對比分析，提出了雙曲線法計算最終沉降量較符合廣東珠三角地區，並提出較符合地區特點的沉降修正系數取值范圍，可供類似工程參考。
