There is an indefiniteness in the wave number that is related to the finite length of the train . 由于波到的长度是有限的,因此相应地在波数上存在着不确定性。
A rational function is continuous on any finite interval where the denominator is bounded away from zero . 有理函数在任何有限区间上都是连续的,其中分母远离零值。
For practical application the integrals in (3. 79) and (3. 80) have to be replaced by finite series . 为了实际应用,(379)和(380)里的积分项必须用有限级数代替。
For some centuries before there was experimental proof, it was believed that the speed of light must be finite . 在有实验证明以前好几个世纪,人们就已相信光的速率必定是有限的。
On a singular surface of order 1 the deformation gradient and the velocity of the medium may suffer finite discontinuity . 在1级的奇面上,媒质的形变梯度和速度可以经受不连续性。
The flow of heat requires finite time, so any process performed quickly enough will be practically adiabatic . 因为热流需一定的时间,所以足够快速进行的任一过程实际上都是绝热的。
The relatively new finite element method and associated variational methods are developing into important numerical tools . 相当新的有限单元法和相关的变分法正在发展为重要的数值手段
To be sure, either the question or the answer must be reformulated in order to bring the finite and the infinite into harmony . 的确须将问题或解答重新叙述借以取得有限维与无穷维间的协调一致。
Unlike in subsonic and transonic speed regimes, the interference resulting from the finite size of the test region is seldom present . 不像在亚、跨音速区域,这里因试验段尺寸有限造成的干扰是难得存在的。
What you want is a philosophy that will not only exercise your powers of intellectual abstraction but that will make some positive connection with this actual world of finite human lives . 你所需要的哲学是这样一种哲学:它不但要能运用你的智慧的抽象能力,还要能与这有限人生的实际世界有某种肯定的关联。
