查询词典 sampling fraction

The excess molar volumes of {1,8- cineole +CCl 4,+CHCl 3} were determined as a function of mole fraction x using a vibrating-tube densimeter at the temperatures 298 15 and 308 15K All mixtures exhibit negative values over the entire composition range at both temperatures.

After taking those factors, such as stable combustion and reducing pollutant emissions into account, the following operation parameters are recommended: combustion temperature between 850℃ and 860℃, excess air coefficient of 1.35, secondary air fraction 40% and mass mixing ratio 30%.

综合考虑稳定燃烧和降低污染物排放等因素，得出一系列最佳燃烧参数。燃烧温度应该控制在850~860℃，过剩空气系数应该控制在1.35左右，二次风率应该控制在40%左右，质量掺混比应该控制在30%左右。

Contemplating the history and development of the museum profession, the comparison that springs irresistibly to mind is with the coelacanth, that remarkble creature whose brain, in the course of its development from embryo to adult, shrinks in relation to its size, so that in the end it occupies only a fraction of the space available to it.

我在考察博物馆专业的历史和发展时，常不自禁的将之拿来和腔棘鱼相比，这是一种特殊的鱼类，它的脑袋在发育过程中逐渐萎缩，以致成鱼的脑袋只占了脑壳的一小部份，与其偌大身躯几乎不成比例。
