After Harrison Ford's first performance as a hotel bellhop in the film Dead Heat on a Merry-Go-Round, the studio vice-president called him in to his office."Sit down kid," the studio head said,"I want to tell you a story. The first time Tony Curtis was ever in a movie he delivered a bag of groceries. We took one look at him and knew he was a movie star."
当Harrison Ford第一次在 Dead Heat on a Merry-Go-Round出演一名旅店侍者后,工作室的副主席把他叫到了办公室"孩子坐下吧",这位工作室的头说,"我想给你讲一个故事,当Tony Curtis第一次出现在镜头前时,他是在运一包货物,我们看了他一眼就知道这个人将是个电影名星。"

The conclusions were as follows: theνO-H andνC=O IR absorption maxima shifted towards higher wave numbers after imprinting 17β-estradiol on TFMAA-co-TRIM copolymer with the red shift of theνO-H groups being apparent after precipitation polymerization for 16h while that forνC=O groups being observed after polymerization for 24h. A strong interaction between TFMAA and 17β-estradiol was confirmed by the high selectivity for 17β-estradiol, as indicted by the values of the separation factor of isomers of 17β-estradiol/17α-estradiol (2.28) and the imprinted factor (3.01). Particle diameter of TFMAA-co-TRIM polymer was between 300 nm and 1.5μm, which suited well for solid phase sorbent throughout at low column pressure. The recognition of imprinting TFMAA-co-TRIM polymer for sterol molecules was driven by enthalpy eluted with acetronitile, and low temperature was in favor of the separation of sterol structure analogues on imprinting column. TFMAA-co-TRIM polymer possessed of determinate anti-heat stability, with melting point beginning at 255.84℃, Tp=257.40℃, control TFMAA-co-TRIM polymer and imprinting TFMAA-co-TRIM polymer were respectively decompounded at 267.79℃and 343.11℃, and solid micro-extraction noddle prepared by the special polymerization also showed definite recognition for 17β-estradiol by GC/MS detecting at 270℃. By selection of various washing and elution solvents, elution reagents of close polymerization system were of more advantage in template molecules retention and recognition on molecularly imprinted solid phase extraction column. At a certain extent, progesterone, 17α-estradiol, 17β-estradiol and 4-androstene-3, 17-dione could be intercepted on the MISPE column. Especially, MISPE had high selectivity for progesterone, and imprinting TFMAA-co-TRIM polymer could achieve adsorption balance within 50 min by absorption kinetics test for 17β-estradiol. However, MISPE column showed better selectivity and enrichment property for 17β-estradiol than C18 and CSPE columns according to the data from HPLC and GC/MS analyses. Recovery of 17β-estradiol on MISPE column was up to 85.5% while when prime extracting solution of milk powder was sampled, the recovery of CSPE and C18 columns were 43.7% and 30.7%, respectively.

Different kinds of flocculants have different capabilities. The flocculants produced by Aspergillus parasiticus is not steady for heat. The flocculating effect is best at acid conditions, and it is not acute for Ca〓. The flocculant can decolorize soluble dyestuff, even the active gorgeous red X-3B which is difficult to be decolorized, the decolor rate is 62. 1%. The flocculant produced by A-9 is steady for heat. It can flocculate Gaolin suspension well without synergistic effects of CaCl〓, and the dose is only 0.05ml/L. The obvious character of A-9's medium cultured for 3days is very viscosity, and viscosity is a mark for microorganism producing microbial flocculants.
