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.

By research on the concentration change and distribution of methyl bromide in the container, we found that in the first period of fumigating, the absorption of the goods to methyl bromide became quickly, so did the concentration decline of the fumigant because of leakage of the carton itself. The distribution of the fumigant is not uniform in the aclinic and vertical directions. The absorption of the goods to methyl bromide completed after 6 hours delivered the gasified fumigant and the distribution of the concentration in space got balance.

After finish the digestion, then flow back to the blood.also, during the period of liver and gallbladder concertrate in the hepatoenteral circulation,the bile acid can drain massively with the excrement.and more seriously after adding the fat feed stuff.if this condition go on, the fat cannot be absorbed in time and the energy will be wasted and cause some disease and etc.but after adding the appropriate exogenetic emulsifier,the question can be solved.
作为正常的机体,胆汁酸由肝脏分泌,进入肠道,在完成消化,回流入血液,又在肝脏和胆囊重新富集的肝肠循环的过程中,会经过粪便大量流失。在脂肪含量较高的饲料配方下,流失更为严重。日肝脏分泌量不足弥补流失量,会造成脂肪消化的阻滞,能量的浪费,且易诱发肝胆代谢紊乱等各种疾病。得不到消化吸收的油脂,在肠道内被噬油微生物降解,使噬油微生物类群大量增殖,打破原来肠道内微生态平衡,产生腹泻等菌群失调症,以上的问题,都是由于脂肪乳化作用不足和脂肪代谢失调造成的。在补充了合适本物种须求的外源性乳化剂后,问题可得到解决。
