You must also enable gravure printing station after the fountain once or twice before going into production to keep the memory in the original phase when closing operations will not be released, the business card printing and membership card making and disnature, die-cutting location, operation difficult complex.

还必须使凹印站润版后到二次投入生产前，保持记忆在原版相位时进行合压操作，才不致于再投入后，制卡和会员卡制作与模切位置错位，机构复杂，操作难度大。

The leftover from bamboo processing was comminuted into bamboo fine powder, which was surface-treaded with a coupling agent of ethenyl tri (β-methoxyethoxy) silane; and then in the presence of initiator dicumyl peroxide, the powder was compounded with styrene-isoprene block copolymer/bromobutyl rubber blend to prepare a crosslinked vibration-absorbing rubber composite material.

将竹加工的边角料粉碎并用乙烯基三硅烷偶联剂处理，再与苯乙烯－异戊二烯嵌段共聚物和溴化丁基橡胶的共混物进行复合，在过氧化二异丙苯引发剂的作用下制得交联型橡胶吸振复合材料。

Carbamide reacting with H2SO4 forms aminosulfonic acid. Allantoin is prepared by oxidation of the aqueous solution of glyoxal into glyoxylic acid which is then used to synthesize allantoin.

氨基磺酸的合成是用尿素和发烟硫酸反应；尿囊素的合成是用硝酸氧化乙二醛溶液制得乙醛酸后，再加入氢氧化钙和氯化钙，使乙醛酸以钙盐形式析出，然后在盐酸介质中与尿素缩合而成。

Ordered Sr_2CeO_4 nanowire arrays embedded in anodic alumina membranes were fabricated by a converse transport technique that precipitations were shaped into one dimension structure in the hexagonally ordered nanochannels of the AAM and changed into the Sr_2CeO_4 nanowire by the subsequent treatment.
