乙醛

Hypoxia was imposed to the cardiomyocytes with or without daidzin pretreatment. ALDH2 activity was measured by the method of acetaldehyde metabolism. Apoptosis was measured by Hoechest 33324 staining, fluorescence activated cell soiling and the DeadEnd fluorometric TUNEL system.

运用缺氧模型，比较大鼠心肌细胞在单独缺氧和经ALDH2特异性抑制剂daidzin预处理24h后缺氧的凋亡改变，酶活性检测采用乙醛代谢法、凋亡的测定通过用Hoechest 33324、免疫荧光标记用流式细胞仪测定和TUNEL试剂盒检测。

The relative contents of hexanal, heptaldehyde, 2-butanone, hexanoic acid, decrease in silkies on feeding stuff, The relative contents of acetaldehyde, 2-octanone decrease in silkies on feeding medlar, in primary volatile compounds.

经分析比较：枸杞园散养乌骨鸡肉中，醛类物质的相对含量最大，占48.82%，是饲料笼养的1.27倍。在主要挥发性物质中，己醛、庚醛、2-丁酮、己酸的相对含量饲料笼养乌骨鸡较枸杞园散养乌骨鸡减少，乙醛和2-辛酮的相对含量增加。

Additionally, morphological structure and properties of the TiO_2 prepared by using the conventional heating and microwave dielectric heating were also compared detailedly. Acetaldehyde was chosen as a model reactant to valuate the performance of the samples.

通过自行设计的微波-光催化反应器，在功率100~170 mW、频率36 GHz 的微波和紫外光同时存在下研究了TiO_2对乙醛的光催化氧化性能，并与单纯紫外光存在下的光催化过程进行了比较。

No, Chloral Hydrate has a half-life of only 4 hours in people with a high tolerance.

不是，对&水合三氯乙醛&有较高耐药能力的人，它的半衰期仅为4个小时。

Is this the same with Chloral Hydrate?

那么，&水合三氯乙醛&是否也会出现同样的情况呢？

The toxicologist discovered in addition to the Nembutal present there was also a large dose of Chloral Hydrate.

除了&戊巴比妥&外，毒物学家还发现了大剂量的&水合三氯乙醛&。

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。
