硫脲

Its preparation method includes the following steps: the urotropine, sulfourea and aminobenzene are placed in the reactor in which the water is held, stirred for 1-2 hr, then the hydrochloric acid is added, and stirred for 1-2 hr so as to can obtain the invented product.

其制作方法是：首先将乌洛托品、硫脲、苯胺依次加入装水的反应釜中进行搅拌1―2小时，然后再加入盐酸，再搅拌1―2小时即可。

Thiourea can keep polymer solution steady well as antioxygen. And micromolecule-alcohol can associate with polymer, which maintains the network structure of polymer.

其中硫脲能起到抗氧剂的作用，在短期内能使溶液保持较好的稳定性；小分子醇类能与聚合物交联，使疏水缔合聚合物溶液的网状结构得以维持。

The mechanisms of photoreaction of benzamide and thiureas have been proposed.

提出了苯甲酰胺和硫脲衍生物的光反应机理。

All rats were fed a low-fat diet supplemented with 4% cholesterol, 1% cholic acid, and 0.5% 2-thiouracil.

大鼠接受添加4%胆固醇，1%胆酸以及2%硫脲嘧啶的低脂饮食饲养。

By testing the corrosion rate of carbon steel in a simulating corrosion system, the corrosion inhibition performance of three corrosion inhibitors (2-methyl imidazone, N-methyl diethanolamine and thiourea) and their compounds was investigated.

通过测试碳钢在模拟腐蚀体系中腐蚀速率的方法，考察了2-甲基咪唑啉、N-甲基二乙醇胺和硫脲3种缓蚀剂的缓蚀性能及其复配效应。

The fact that only the SERS spectrum of PATP is observed from the assembly, where PATP is partially replace d with N,N'-diphenylthiourea, demonstrates that the electromagnetic field is mainly localized in the region between the silver particles and the surface of the silver metal.

实验中发现只有组装阵列上的PATP分子的SERS被观察到，而部分替代PATP的二苯基硫脲的SERS信号没有得到，说明电磁场主要集中在银粒子和金属银表面之间的这一区域。

But copper dissolves less, and silver、nickel and iron is hardly dissoluble, because of passivation of black Ag〓S and Cu〓S layer and sulfide film of nickel and iron.

在碱性硫脲溶液中，银、铜几乎不溶解是因为黑色的Ag〓S和Cu〓S膜的钝化，铁、镍不溶解亦是其硫化物膜钝化的结果。

Preparation of formamidine sulphinic acid with thiourea and hydrogen peroxide by aqueous solvent process was researched.

研究了硫脲与双氧水水溶剂法制备甲脒亚磺酸的反应。

Firstly, polyacrylamide with 26 million molecular weight was compounded in lab through establishing optimum compounding initiator proportionality of 1:1. 3 and mass concentration of 170 mgL^(-1), temperature of 10 ℃, acrylamide mass percentage of 25%, electrical conductivity of 3.6 μSm^(-1) and pH value of 6.57. The salt-resistance, thermal endurance and shear-resistance of polyacrylamide could be enhanced b introducing sulfonic acid group or styrene sulfonate group or drawing the two groups above at the same time. Secondly, chelator HEDP, bactericide isoquinoline ketone and oxygen scavenger thiourea were optimized to improve the compatibility of polyacrylamide and formation water.

在由室内试验确定了复合引发剂最佳比值1：1.3和质量浓度170 mgL^(-1)、合成最佳温度10℃、丙烯酰胺单体质量分数25%、电导率3.6μSm^(-1)和pH值6.57后，合成出相对分子质量高于2.6×10^7的聚丙烯酰胺，同时通过丙烯酰胺单体复配引入磺酸基团、苯乙烯磺酸基团或同时引入此两种基团，提高了聚合物的抗盐、抗温、抗剪切性能；后针对聚丙烯酰胺与地层水配伍性差的问题，优选出HEDP螯合剂、异噻唑烷酮杀菌剂和除氧剂硫脲，对聚合物稳定效果明显。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
