查询词典 react on

People do want to know that there is somebody on the system that can react to an emergency, but if driverless operation means that there are more staff at stations, or in the passenger accommodation of a train, rather than locked away in the cab, this seems to be where passengers want to see staff.

相反，如果无人驾驶可以让车站有更多人手，或者让更多的服务人员值守在乘客车厢内，而不是远远地锁在驾驶室，这反而符合了乘客的意愿。他们希望看到有穿制服且有职权的人在近旁，不是司机也行。"引语"'移动闭塞'，当然还有ERTMS，都要求配备具有足够宽带的可靠通信干线。——奥雅纳环球路桥技总监

一方面，一些人厌烦了喋喋不休地讨论世界末日。12月5日，许多非政府组织将在伦敦上演示威活动，该示威活动的协同组织人阿什克·辛哈指出，有些民众对于可怕预测的反应是&封仓或是退却&。

The extraction and stability of the pigments in Tussilago farfara L. were studied. The experimental results showed that the pigments could be solved in acetone. The stability of the pigments is good when pH is within 3~9; the oxidizing agents, reducing agents and common food additives have little influence on its stability; it is react too much with Fe(superscript 3+) ion, and Na(superscript +) ion showed a certain increment effect on the color; the heat performance of the pigments is good when under 60℃.

研究了款冬花色素的热稳定性、氧化还原稳定性和pH值稳定性，并对常用的几种食品添加剂对款冬花色素的稳定性进行了探讨，结果表明：款冬花色素易溶于丙酮，属于脂溶性色素；在pH＝3～9时，款冬花色素的稳定性较好；氧化还原剂及食品添加剂对其稳定性影响不大，Fe(上标 3+)金属离子对其影响显著，Na有增色作用；水浴温度在60℃以下色素的热稳定性较好。

One route was that the amino-groups on the silica gel were transformed to tertiary amines by Eschweiler-clarke reaction that amine-groups react with formaldehyde and methanoic acid to prepare tertiary amines; the silica gel intermediates with tertiary amine groups reacted with chorohydrocarbons to prepare insoluble silica gel quaternary ammonium salt bactericides. Another route was that the amino-groups on the silica gel reacted with excessive chlorohexadecane; the preparing intermediates were quaternized with iodomethane to obtain insoluble silica gel quaternary ammonium salt bactericides.

一条路线是根据埃施韦勒-克拉克(Eschweiler-clarke)胺甲基化反应，进行胺基叔胺化反应，制成带有叔胺官能团的硅胶中间体，此中间体上的叔胺与卤代烷反应生成杀菌活性官能团季铵盐，制成硅胶类水不溶性季铵盐杀菌剂；另一条路线是带有胺反应活性中心的硅胶与过量正氯代十六烷反应，得到的中间体再用碘甲烷季铵化，得到最终产品——水不溶性季铵盐杀菌剂。

Co-firing characteristics of corn stalk and stone coal in different proportion were investigated by thermal gravimetric analysis. The results showed that corn stalk can improve the ignition and combustion of stone coal. The agglomeration experiments on corn stalk were made in a bench-scale bubbling fluidized bed with quartz sand as bed material and stone coal ash as additive. The results indicate that stone coal ash can inhibit agglomeration of bed material particles at temperature of 900℃. Agglomerate of blends was analyzed by means of scanning electron microscopy, energy-dispersive X-ray, and the bed materials were analyzed by means of X-ray fluorescence. Analysis showed that aluminum element and iron element in stone coal ash can react with alkali compounds and eutectics with low melting point, form a covering layer with high melting point on the surface of biomass and quart sand particles, thus inhibit the forming and transfer of low melting compounds.

以玉米秸秆与石煤按不同比例组成的混合物为研究对象，在TG-DTG热分析仪上进行了燃烧特性分析，结果表明玉米秸秆有利于石煤的着火和稳定燃烧，对石煤有一定的助燃作用；在小型鼓泡流化床实验装置上，以石英砂为床料、石煤灰为添加剂，进行了玉米秸秆成型燃料流化床燃烧的床料黏结实验，结果表明：石煤灰能够在生物质流态化燃烧过程中有效地抑制流化床床料黏结现象的发生；通过对实验中形成的结团进行扫描电子显微镜X射线能谱(scanning electron microscopy/Energy-dispersive X-ray- SEM/EDX)，对床料进行X射线荧光光谱(X-ray fluorescence，XRF)分析，结果表明石煤灰中的Al和Fe能够与生物质灰中的碱金属化合物以及低熔点共熔物发生化学反应生成高熔点物质，并且覆盖在生物质碳颗粒与石英砂颗粒表面形成隔绝层，从而阻止低熔点物质的生成与迁移。

P and 〓Si MAS NMR results show that both Si-OH groups on the pillars and P-OH groups on the layers react with the Ni〓 and form Si-ONi and P-O-Ni bondings, resulting in a more homogeneous dispersion of the NiO in the interlamellar region.

元素分析表明新方法中未焙烧的前驱体的层间存在大量的胺基，可能与镍产生配合作用，有利于金属离子进入层间。

P and 〓Si MAS NMR results show that both Si-OH groups on the pillars and P-OH groups on the layers react with Cr〓 to form Si-O-Cr and P-O-Cr bondings in Cr〓O〓-SiO〓-ZrP, resulting in a more homogeneous dispersion of the chromium oxide in the interlamellar region.

用〓P和〓Si NMR表征时同样观察到传统方法中氧化铬主要与硅柱作用，与层板几乎不作用，而新方法中氧化铬与层板和硅柱均有强相互作用，使氧化铬更均一地分散于层间区域。

The morphological analysis and chemical characterization of the worn surfaces via scanning electron microscopy, laser scanning microscope, and X-ray photoelectron spectroscopy reveal that under titrimetric water lubrication, the hBN in Si3N4-hBN spalled off during the wearing tests and the spalled pits formed on the wearing surface of Si3N4-hBN, and then the debris dropped into the pits to react with water, thus a tribochemical film formed on the wearing surface. The formation of the tribochemical film facilitated smoothing the surfaces of Si3N4-hBN and Si3N4 to create a fine lubrication environment.

在滴定法水润滑条件下，磨屑不易被水带走，当Si3N4-hBN与Si3N4配副摩擦时，由于Si3N4-hBN摩擦面上hBN偏聚区域发生脆性断裂和剥落而形成剥落坑，磨屑在剥落坑中堆积并氧化、水解，反应产物富集于剥落坑中，进而在摩擦表面形成含B2O3和SiO2的摩擦化学反应膜，从而保护了Si3N4-hBN和Si3N4摩擦面，使其变得光滑，为发生流体润滑提供了条件。

Then, the outraged hawk, folded up both its wings, drove like an arrow from the sky swooped down on the quail. But when the quail knew "That hawk has come close", it slipped under the clod and unable to react, the hawk shuttered its head right on the spot.

於是，盛怒的大鹰，收起两翼，从空中像箭一样地俯冲下来，扑向鹌鹑，鹌鹑算准了时间，躲到了大土块下面，大鹰来不及反应，结果，就一头撞死在大土块上。
