Result The results showed that the cutting survival rate and propagation coefficient were higher in interlayer scale, the difference of which was not obvious between outside and inside scales. Compared with integrated scale, cross cutting and score cutting scale all could reduce scale propagation coefficient Treating scale with 0.1% HgCl2 could prevent scale rot effectively and increase propagation coefficient Integrated scale without segmentation was good for lily bud scale cutting.

In the traditional GSM network planning, the revised Hata model serves as the prototype, and the coefficient in the model formula is tuned according to the data obtained in the radio propagation feature test specific to local actual radio environment, so as to obtain the propagation model for practical prediction. A common digital map only contains the clutter information and the digital terrain model information. So the building designers cannot fully allow for the influence of radio propagation, and can only estimate the influence on the building roughly from a traditional perspective, e.g., consider the influence of different clutters through certain clutter offset.
在传统的GSM网络规划中,一般都以修正的Hata模型为原型,再利用规划软件通过导入针对当地的实际无线环境做无线传播特性测试所得的数据对模型公式中的系数进行修正而得到实际预测用的传播模型,一般使用的数字地图仅包括地物信息和高程信息,因此建筑物对无线传播的影响无法充分考虑,只能从统计意义上对建筑物的影响进行粗略的估计,如通过一定的地物偏移来考虑不同地物的影响。

After comparing nonlinear simulation with linear, the results indicate that: Weak nonlinearity has definite and apparent influence on the distribution of acoustic fields and focused gain of array, which cause the distribution of waveform is closer to the array and the focused gain deteriorate ; the strong nonlinearity have a strong waveform aberration, because the other waves of non-fundamental frequency appear . No evident distinction is found in the effects between the oblique propagation and the vertical propagation, though less focused gain and influence caused by strong nonlinear produced by the acoustic diffraction which results in more attenuation in terms of oblique propagation.
将线性条件下的模拟结果与非线性条件下的模拟结果进行比较发现:弱非线性会对声场的分布和阵列聚焦增益产生一定的影响,使得声场分布波形比线性条件下的更加靠近阵列,聚焦效果变差;强非线性会使波形发生更严重畸变,这是由于产生了基频以外的其他频率声波引起的;非线性对斜向传播时声场分布的影响与垂直传播时的影响效果基本相同,但由于斜向辐射时的声波衍射造成的衰减要大于垂直辐射时的,因此聚焦增益和强非线性的影响都将小于垂直辐射时的情况。
