The absorption spectra of the terpyridyl platinum acetylide complex containing monoazacrown moiety in the acetylide ligand was blue-shifted upon complexation with metal cations.

对位带有氮杂-15-冠-5冠醚的苯乙炔为辅助配体的三联吡啶Pt络合物TAC在金属离子的存在下吸收光谱的变化明显不同。

The disproportionation of COS leads to the formation of CS_2. Most of CO_2 originates from water-gas shift reaction.

水煤气换反应是CO_2的主要来源；CS_2是COS的分解产物；CH_3SH的二次反应导致碳氢化合物和硫醚的生成。

Under these conditions, the dependence of the iC4 conversion to MTBE on the reboil ratio follows the same trend as its dependence on the reflux ratio.

在这些条件下，依赖的丁烷转化为甲基叔丁基醚的reboil比例如下相同的趋势，因为它依赖回流比。

I/R-induced depression in cardiac performance is associated with a down-regulation of the major sarcoplasmic reticulum Ca2+-cycling proteins.

异氟醚的预处理阻止 RyR2和 SERCA2a 在 I/R 相关的降解，但它独立于敏感钾通道组的激活。

The results showed that silver ion can complex with segregative carbon-carbon double bonds in DHA ester, with isolated C=C bonds in allyl ether and with conjugate C=C bonds in benzene individually.

研究结果表明，银离子可以与DHA乙酯的隔离碳—碳双键、烯丙醚的孤立碳—碳双键及苯的共轭碳—碳双键形成络合物。

However, due to the side-effect to environment and human health, MTBE will be banned in United States and replaced by other less harmful oxygenates. So, it is necessary to find the substitute of MTBE.

但是，近几年，因其对人体及环境的负面影响，在美国有被禁用的趋势，因此，有必要寻找甲基叔丁基醚的替代品。

Separation of racemic mixtures of benzyl glycidyl ether was achieved with HPLC by using Chiralcel OD as chiral stationary phase and hexane/2-propanol mixture of different ratios as eluents.

在 Chiralcel OD多糖类手性固定相上，以各种不同配比的正己烷-异丙醇为洗脱剂，对苄基缩水甘油醚的外消旋体进行对映体拆分，考察了不同洗脱剂配比、柱温和流速对分离度和出峰时间的影响。

The dark oxidation control of ethers via controlling the formation and equilibrium of 〓-CCT was preliminary discussed.

6利用〓-CCT的理论，通过控制〓-CCT的形成及平衡，对醚的暗氧化控制进行了初步探讨。

However, in contrast with the extensive employment of cyclodextrins and crown ethers, the application of calixarenes in CE was limited.

但与环糊精和冠醚的广泛应用相比，杯芳烃在毛细管电泳中的应用研究才刚刚开始，是一个有待开发的新领域。

METHODS: In rats prepared with chronic indwelling catheters or stylets, we infused solutions deficient in Na+ and with an excess of Na+ into the lumbar subarachnoid and intracerebroventricular spaces and measured MAC for isoflurane before, during, and after infusion.

我们通过大鼠身上的留置管或留置针在腰椎的蛛网膜下腔和脑室内注射无钠溶液或重钠溶液，并分别在注射前、注射中和注射后测量异氟醚的 MAC 值。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
