Thirdly,it presents the mechanisms of preventing market pricing in aluminum industry,that is to say,making a price lower than the induced entering price to prevent entering the market.This price makes the potential enterer recognized that when they entering the market,the expected income will be offset by the cost of overcoming the market entering barrier or suffering retaliation.Thereby they give up their access of entering.

第三，提出铝工业市场的阻止进入定价的机理，即通过制定低于诱发进入的价格来防范进入，这一价格水平使潜在进入者认识到进入市场后，预期获得回报将与克服进入障碍以及遭到报复所付出的代价正好相抵，从而放弃进入。

Antecedent trial, SAINT I, and the critical commentary stimulated by it, which called attention to its interpretively challenging primary outcome measure—a shift in the full-scale modified Rankin scale score—and to other statistical shortcomings;(2) the cogency of the STAIR recommendations, to which the development of NXY-059 closely adhered; and (3) the inherent physiochemical shortcomings of NXY-059 as a neuroprotective agent—its polar, nonlipophilic nature, poor blood– brain barrier penetrability, nonphysiological oxidation potential, and low potency.

应注意SAINT I期试验有争议的结局指标以及统计方法的缺陷；（2）NXY-059试验严格遵守STAIR推荐；（3）NXY-059作为神经保护剂固有的生理生化性质的缺陷：该药的极性、非脂溶性、较差的血脑屏障穿透性、无生理性的氧化能力以及低效价。

Only when the outer electrons forming dangling bonds absorb noncontiguous specific energy and transit into relative free status, can they bond with each other, that is, only when C atom in 3DB status takes in enough energy and conquers potential barrier can it realize reconstruction.

构成悬挂键的外层电子只有吸收非连续的特定能量跃迁成相对自由状态才可能彼此成键，即处于3DB状态的C原子吸收足够能量克服势垒才能实现重构。

They are already being evaluated in clinical trials as potential therapeutic agents for major human neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and motor neuron disease. However, delivery of polypeptide growth factors to compromised neurons in the CNS is problematic because their plasmatic half-life are very short and their abilities to cross the blood-brain barrier are theoretically null.

然而由于中枢神经系统中存在血脑屏障，神经营养因子类物质难以通过血脑屏障而到达靶部位；同时又因为神经营养因子在体内生物半衰期较短，使得全身性用药效果不够理想，另外还往往产生意想不到的副作用，如何解决这些问题对于深入研究神经营养因子在神经损伤及神经系统退行性疾病中的作用及开展临床应用前景研究有着十分重要的意义。

The measurement of acid dispersion index indicates that the pseudo-boehmite powder canbe peptized completely. When n_H+/n_AlOOH·nH2O =0.097, the corresponding pH value is 3.4. The calculated potential barrier is 6.31 ×10~-18J according to DLVO model. The size of the colloidal particulates is around 5-10nm, being cross-link as is shown by TEM.

酸分散指数的测定表明当n_/n_(AlOOH·nH_2O)=0.097时，拟薄水铝石可以完全胶溶，稳定水溶胶的pH值为3.4；根据DLVO模型计算的位能势垒为6.31×10~(-18)J；TEM观察溶胶的胶粒为5-10nm，且部分粒子相互网联。

The blue detuned laser beam is physically equal to a quantum potential barrier.

作为量子力学中的一个基本现象，量子隧穿效应一直是科学界长期关注与研究的一个重要问题。

Currently, there are three major obstacles to performing transplantations from pig to man: a powerful immune barrier, a potential risk of transmitting microorganisms, particularly endogenous retrovirus, and ethical issues related to the future recipients and to society at large.

目前，对于实施猪到人的器官移植，有3个主要障碍：强烈的免疫排斥；跨种系感染的潜在危险，特别是内源性逆转录病毒；将来对移植受体和社会的伦理问题。

He became prime minister in 1997 and won international acclaim for his role in the Northern Ireland peace process.

他在1997年成为总理，并且因为在北爱尔兰的和平进程中发挥的作用受到国际社会的赞许。

Mixed Page Sorting Method Using the cuttable user model, this thesis proposes a mixed page sorting method by using cutted user model in server-side and complete user model in client-side.
