求翻译：式中a 为所有影响因素均为0时（记作x =0），个体发生事件概率与不发生事件的概率之比的自然对数值。 b某影响因素 x改变一个单位时，个体发生事件概率与不发生事件的概率之比的自然对数变化值。即：是什么意思？

Where a is the all factors are 0:00 (denoted by x = 0), the ontogeny of the natural logarithm of the ratio of event probability and the probability of events. a b impact factor x to change a flat, individual probability of events and the ratio of the probability of an event does not occur naturally

In all the effects for a factor when you are 0 for X = (Note 0), individual events do not occur with probability ratio of the probability of events in the natural logarithm. Factors affecting B X a change when a unit, and individual events do not occur with probability ratio of the probability of th

In the formula a is all influence factor is when 0 (records makes x =0), the ontogenesis probability of event with does not have the event ratio of probability nature to the value. When the b some influence factor x changes a unit, the ontogenesis probability of event with does not have the event ra

Type a is all the influencing factors are 0 o'clock (recorded as x=0), individual event probability of occurrence and not natural values of the ratio of the probability of an event occurs. B when an impact factor x to change a unit, individual event occurs probability event does not occur and the na
