The inhibition mechanism of MoO42- was that MoO42- transformed the hydrate ferrous oxide deposition film from anions selective to cations selective,and the cathodic process of underscale local corrosion was suppressed when it migrated into OCC.Meanwhile, the migrated MoO42- resulted in increasing the impedance of the film on the substrate metal and so inhibited the anodic process of the corrosion reaction inside the OCC.

MoO42-的作用机制在于使水合氧化铁腐蚀膜由阴离子选择性变为阳离子选择性，H+可以从膜下扩散出去，而Cl-难以扩散到膜下富集，抑制了腐蚀反应的阴极过程；同时MoO42-迁入闭塞区后增大了电极表面膜层阻抗，抑制了腐蚀反应的阳极过程。

The catalytic activity is much higher than that of the unpromoted sample Fe/Zr, while light olefins selectivity decreases and methane formation increases.

对南海涠洲11-4油田C4水平井底水脊进的原因进行了分析，提出利用选择性堵剂和选择性注入及过顶替的方法来控制底水脊进。

The female weevils oviposited on mung beans as well as adzuki beans in no-choice test, while they preferred adzuki bean over mung bean in choice test. To study the relationship between oviposition behaviour and host preference, three treatments (A: pure adzuki beans; M: pure mung beans; Mixed: mixed adzuki beans with mung beans) were provided to the female.

过去的研究报告指出，雌豆象成虫利用相对法则检视寄主品质，以决定是否产卵於寄主豆上；而且在非选择性试验中，雌虫产於绿豆或红豆的卵数相等；但在红、绿豆选择性试验中，雌虫则偏好产卵於红豆。

They are①ANN based nonlinear coding method to reduce coding delay②the conversion method of CBR streams to VBR streams to make the packeting delay negligible③human perception based main and subordinate packet method to reduce the influence of packeting delay④cell selective discarding and datagram selective shorten method to reduce queuing delay by alleviating the load of links⑤multitask cell or datagram multiplexing method to reduce packeting delay.

作者研究的重点，在于提出了若干降低编码、信息分组装配和分组排队时延的新方法，它们是：降低编码时延的ANN非线性编码法、大幅度降低分组装配时延的CBR码流VBR转换法、基于人耳听觉特性的主次信息分组装配降低时延法、新的降低排队时延和网络拥塞状态的信元选择性删除和数据报选择性截短适配法，以及降低分组装配时延的多任务复合装配法。

The yields of furfural derivatives both in water and in methanol reach the maxima in the vicinities of the critical pressures.

停留时间越长，葡萄糖在超临界水和甲醇中的转化率越高，HMF的收率和选择性越低，而MMF的最大收率和最高选择性却存在着一个适宜的停留时间。
