这些紧致化的每一种将导致一个不同物理法则的宇宙--如不同的电子质量和引力常数。
Each of these compactifications will result in a universe with different physical laws- such as different masses of electrons and different constants of gravity.
物理学家喜欢这个数字不仅仅是因为他是无量纲的,还因为它是自然界中三个基本常数的组合。
Physicists love this number not just because it is dimensionless, but also because it is a combination of three fundamental constants of nature.
如上所述,酶抑制剂的特征在于对酶和酶-底物复合物的两个解离常数Ki和Ki′。
As noted above, an enzyme inhibitor is characterised by its two dissociation constants, Ki and Ki', to the enzyme and to the enzyme-substrate complex.
时间也称为瞬态响应,电容器完全充电所需的时间相当于约5个时间常数或5T。
The time also called the transient response, required for the capacitor to fully charge is equivalent to about 5 time constants or 5T.
与其他原子系统一样,离子具有很大的优势,即它们的自然跃迁频率仅由物理常数和量子力学决定。
Ions, like other atomic systems, have the great advantage that their natural transition frequencies are determined solely by physical constants and quantum mechanics.
电机工程师、电子工程师、电气工程师以及飞机工程师都使用相量图使複常数和相量变量可视化。
Electrical engineers, electronics engineers, electronic engineering technicians and aircraft engineers all use phasor diagrams to visualize complex constants and variables(phasors).
在这些讲座,他谈到了宇宙学的问题,或更准确地说,应该是问题的非三维组合的世界常数。
In these lectures he spoke about the problems of cosmology or, to be more precise, to the problems of non-dimensional combinations of world constants.
如果NULL和0作为空指针常数是等价的,那我到底该用哪一个?
If NULL and 0 are equivalent as null pointer constants, which should I use?
默认值必须是常数,不能是一个函数或表达式。
The default value must be a constant and cannot be a function or an expression.
若达K常数及m常数滤波器组成级联电路,可获得尖锐的滤波作用及良好的频率衰减。
If the constants of K and m are constant filter composed of cascaded circuit, get sharp filtering effect and good frequency attenuation.
第一次把e看为常数的是雅各布·伯努利,他尝试计算下式的值:.
The first indication of e as a constant was discovered by Jacob Bernoulli, trying to find the value of the following expression.
如果K是常数,则将黑体和受体的面积以及二者间的距离考虑在内。
Where K is a constant, taking into account the areas of the blackbody and receptor and the distance between them.
材料性质可以是常数,也可以是一个或多个独立变量的函数。
A property may be a constant or may be a function of one or more independent variables.
由于常数除以无穷大等于0,我们最终得到:.
Since a constant divided by infinite equals to 0, we end up with.
第一步,用关键字k乘上常数A(0<A<1),并抽取出kA的小数部分。
First, we multiply the key k by a constantA in the range 0< A< 1and extract the fractional part of kA.
在意大利的里雅斯特天文台研究常数变化的保罗莫拉罗(PaoloMolaro)对此表示赞同。
Paolo Molaro, who researches variations in constants at the Astronomical Observatory of Trieste, Italy, agrees.
