总结了正统的量子观测理论，并将其应用于粒子探测。在规定的时间内，通过一个计数器、两个计数器和三个计数器计算瞬时观测的概率和状态向量。同样的情况下，然后审查的背景下，相对论理论。人们发现，如果试图检测一个给定的粒子在两个时空区域，有空间一样的分离，非相对论概率公式必须补充额外的条件，被检测到的粒子的波函数变得模糊和noncovariant。这种不确定性并不影响那些对波函数的影响已经被考虑在内的观测值的任何概率，而且，通过暗示，这些是概率可能受到所讨论的不确定性影响的唯一观测值。这些结果的可能后果进行了简要讨论。
The orthodox quantum theory of observations is summarized and then applied to particle detection. Probabilities and state vectors are worked out for instantaneous observations, at stated times, by one counter, two counters, and three counters. The same cases are then examined in the context of a relativistic theory. It is found that, if attempts are made to detect a given particle in two space-time regions that have space-like separation, the nonrelativistic probability formulas have to be supplemented by additional conditions, and the wave function of the particle being detected becomes ambiguous and noncovariant. This ambiguity does not affect any probabilities for observations whose effect on the wave function has already been taken into account, and these are, by implication, the only observations whose probabilities could possibly be affected by the ambiguities in question. Possible consequences of these results are briefly discussed.
