Parotid region skin shows vasodilatation, flush and diaphoresis in meal. The mechanism is aberration-regenerate theory. The treatments include drug treatment, local treatment and operation treatment. The obviate is to put interval stuff in operation, skin flap can prevent nerves wrong to unite on parotid raw surface. It can barricade insulate the wrong unite of parasympathetic nerve and reign skin interneural if insert apo-cell subcuticula ground substance in operation.

Based on the analysis of error characteristics and performance effect of the mostly used crystal oscillator, a method to simulate the frequency error of crystal oscillator is proposed. The major idea is to determine the Allan variance parameter of each main stochastic error component at the given sampling interval at first, then to deduct a set of corresponding frequency error series and superpose them together.

该文对在GPS接收机中使用最多的晶振的误差特性和性能影响进行了分析，在此基础上提出了一种模拟晶振频率误差的方法，即首先确定晶振在给定取样时间间隔上各主要随机误差成分的Allan方差参数，由此反演产生相应的各项晶振频率误差模拟序列并进行叠加。

Studies on statistical properties of spontaneous spike trains of single auditory nerve have shown that the distributing patterns of interval in spike trains represent Poisson distribution. Since Poisson distribution is one of the simplest stochastic processes, previous studies on spontaneous spike trains of single auditory nerve were performed primarily by assuming them as stochastic processes. Recently, further studies on nonlinear dynamic system show that we have not enough evidence to demonstrate the process, whose distribution of probability density is exponential, is Poisson process.
