查询词典 x-ray

If you specified an x-value, the coordinate of the new point matches the x-value of the first point and the y,z-value of the second point.

如果你指定了一个x值，新点的坐标将匹配第一个点的x值和第二个点的y，z值。

In a race from point X to point Y and back, Jack averages 30 miles per hour to point Y and 10 miles per hour back to point X.

The results indicated that BaCe0.8Ho0.2O(subscript 3-α) sinters are of single-phase structures of orthorhombic perovskite. In the temperature range of 600~1000℃, the nonstoichiometric materials (x=1.03 and 0.97) have higher conductivities in wet hydrogen and wet air and better performances of hydrogen-air fuel cells than the stoichiometric one (x=1). In this series, BaCe0.8Ho0.2O(subscript 3-α) has the highest conductivities 2.10×10^(-2Scm^(-1) in wet hydrogen, 3.46×10^(-2) Scm^(-1) in wet air, at 1000℃ and the maximum power output density 122 mWcm^(-2 at 1000℃.

结果表明，在600~1000℃温度范围内、湿润氢气和湿润空气气氛中，该系列材料的电导率随温度和钡离子含量的变化均与以该系列材料为固体电解质的氢－空气燃料电池性能随温度和钡离子含量变化的次序一致，即：非化学计量组成材料BaCe0.8Ho0.2O(下标 3-α)(x=1.03， 0.97)具有较化学计量组成材料BaCe0.8Ho0.2O(下标 3-α)(x=1)高的电导率和氢－空气燃料电池输出功率密度，其中BaCe0.8Ho0.2O(下标 3-α)有最高的电导率（1000℃时、在湿润的氢气气氛中：2.10×10^(-2)Scm^(-1)；在湿润的空气气氛中：3.46×l0^(-2)Scm^(-1)）和最大的氢－空气燃料电池输出功率密度（1000℃时：122mWcm^(-2)）。

We will in effect define x to be the set of rationals smaller than x .

我们把 x 定义为小于 x 的有理数集合。

"The idea behind Dedekind cuts is that a real number x can be named by giving an infinite set of rationals, namely all the rationals less than x .

Enderton (p.113)形容了这个描述：戴德金分割背后的想法，是每一个实数 x 都可以用一个有理数的无穷集合，也就是所有小于 x 的有理数来命名。
