possible range

The emluator shows that if the signal power and the atmosphere visibility is enough, the bit-error rate of the laser signal will be very low even through the span beyond the visual range, so the establish of the reliable atmospheric laser communications is possible in the fog.

仿真结果表明，在一定的信号光强和能见度的情况下，即使传输距离超出能见度范围，激光信号传输的误码率也比较低。因此，在雾中建立可靠的大气激光通信是可能的。

The results show that for the given laser flux and target thickness, the spallation is possible only for the laser pulse duration within a certain range and, furthermore, the lowest laser flux for spallation corresponds to the optimum laser pulse duration.

本文结果指出，对于一定的激光通量和靶板厚度，只有一定范围内的激光脉宽才能造成层裂，最低激光通量则对应于最佳激光脉宽。

It is possible that a description of the methods of epidemiology may stimulate the use of these techniques by a wider range of individuals.

在卫生领域的总人力中，经过训练的流行病学家所占比例很小，但这个比例是稳定地增长着。

The distinction is that often when doing validation, the list or range of possible values is smaller than the list of invalid values, many of which can be unknown or unexpected.

两者之间的区别是，通常在进行验证时，可能值的列表或范围小于无效值的列表或范围，其中许多值可能是未知值或意外值。

Atmospheric attenuation of scene contrast is studied theoretically on the basis of radiometric principles, and the relationships between the measured maximal detection range for a target and visibility distance under two possible conditions are obtained.

根据辐射度学原理，从理论上研究景物对比度在大气传输中的衰减，得到了在两种可能的条件下所测得的目标最大探测距离与能见距离的关系。
