在无润滑条件下，反应等离子喷涂TiN涂层的耐磨性明显高于淬火M2钢，在高载荷下，其耐磨性是M2钢的2.5倍；

The wear-resistance of the RPS TiN coating is significantly higher than that of the quenched M2 high-speed steel . The wear resistance of the quenched M2 high-speed steel was improved about 2.5 times by the RPS TiN coating under high load .

二：简单介绍了近年来水介质中无催化剂条件下有机反应的研究进展。

The progress of catalyst-free aqueous-mediated organic reaction were introduced briefly .

邻苯二甲酸酐与乙醇胺在无溶剂的条件下反应，质量收率达到99%以上，质量分数99%以上。

The reaction of phthalic anhydride and aminoethyl alcohol under solvent-free conditions provided a novel route to N - ( 2-hydroxyethyl ) phthalimide with good yields ( > 99 % ) and high purity ( > 99 % ) .

咬伤所带来的疼痛感，和有此所带来的痛苦与恐惧，就是无条件刺激和无条件反应。

Now the pain of a bite , being bit , and then the pain and fear of that is an unconditioned stimulus , unconditioned response .

巴甫洛夫给狗喂食，狗会分泌唾液，这就是无条件刺激引起了无条件反应。

When Pavlov put food powder in the dog 's mouth and saliva was generated , that 's an unconditioned stimulus giving rise to an unconditioned response .

Well , when Pavlov , for instance , started before conditioning there was simply an unconditioned stimulus , the food in the mouth , and an unconditioned response , saliva .
