The results indicate that finishing temperature and coiling temperature have more affects on yield ratio of HP345 steel.Yield ratio will increase when finishing temperature and coiling temperatrue reduced;It is obviously decreased when coiling temperature is equal to 650℃;it is obviously increased while coiling temperature is reduced to 580℃;it is lower and has less variation while coiling temperature is between 610℃ an...

结果表明，终轧温度和卷取温度对HP345钢的屈强比都有较大的影响，降低终轧温度和卷取温度，均使HP345的屈强比升高；卷取温度为650℃时，屈强比明显降低；而卷取温度降至580℃时，屈强比明显升高；卷取温度在610℃~630℃区间变化时，屈强比较低而且变化不大，同时钢具有较高强度。

What We're All About : Nevertheless I'm not dressed for the occasion It's number 32 now here's the situation If the beat moves your feet then don't change the station Pack your bags cause we're leaving on a permanent vacation Well, I'm a disaster A microphone master Put on your tape and rock your ghetto blaster It's not about the money, cars, hotels, or resorts About sweating all the bitches in the biker shorts I'm Dave Brown Sound and you see me running late Cause I'm always making time to make your girlie feel great And I'm Bizzy D from way down town I'm known to rock a mic like a king was a crown When I'm on top I'm gonna borrow that bootie Hustling deals like Mickey Macooty When I wake up I like a pound of bacon Start off the day with my arteries shaking Rock!

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.

The effects of the surfactants, trioctyl phosphine oxide, sodium dodecyl sulfonate and hexadecyl trimethyl ammonium bromide, on the extraction rate of Co^2^+ were investigated. The acceleration in the kinetics in contributed to the associated molecule~2 TOPO taking part in the extraction process directly. The decrement effects of SDS or CTMAB on the rate of extraction kinetics of Co^2^+ with HDEHP were also observed, which caused by the adsorption of molecules of SDS or CTMAB on the interface and decreased the interfacial adsorption amount of HDEHP. In addition, the extraction rate was reduced by a bigger margin in HDEHP-SDS system. This can be explained in terms of the formation of an electric field at the interface.

研究体系中加入不同表面活性剂所引起萃取速率的不同改变：三辛基氧化膦因与HDEHP形成可萃取的Co^2^+活性分子缔合物，降低了萃取过程活化能而使反应加速；十二烷基磺酸钠和十六烷基三甲基溴化铵因占据发生萃取反应的界面区，减小了HDEHP与Co^2^+反应的机会而使反应减速； SDS还因其在界面形成较强的负电场，造成Co^2^+的附加势能而使萃取速率有更大幅度的降低。

The application of ionic liquids aqueous solutions as solvents in the microwave-assisted extraction technique was developed for the extraction of lycorine, lycoramine and galanthamine from Lycoris.

Obsessing aloud, on the other hand, is a way of fishing for pity, a means of extorting attention.

然而，不断提起则是在捞取人们的同情，一种强取注意力的方式。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
