In this paper Ⅰ successfully applied these methods to fault diagnosis, and presenting some new innovative machinery fault diagnosis method; First Ⅰ present a new gear wornout fault diagnosis method, this method use the vibration signal's time-frequency attribute and instantaneous phase undulation to accurately detect gear's fault, and by comparing with the traditional frequency domain analysis method, this method reveals that many nonlinear and nonstationary characteristic exist in gear's vibration, this tell us that if we use frequency domain analysis method without pay attention to the signal's characteristic, we could get wrong diagnostic result; Then Ⅰ present a new bearing fault diagnosis method, this method use ATVFD and Hilbert transform to do envelop demodulation,Ⅰ analyze the envelop with time-frequency method and find out that this method is more accurate then traditional method.Ⅰ also explain that the modulation of the fault to the carrier wave may also be non-stationary and nonlinear; Finally Ⅰ present a cylinder pressure measurement method of diesel engine by means of vibration, cylinder pressure is an important parameter of diesel engine fault diagnosis, the pressure measuring is simplified a lot by this method,Ⅰ also use the ATVFD and time-frequency analysis to realize it.

本文中将上述理论方法成功地应用到故障诊断中去，提出了几点创新性的诊断方法；提出了一种齿轮磨损故障诊断的新方法，该方法利用振动信号能量的时频域分布特征与瞬时相位波动特征可以进行精确的齿轮故障诊断，并通过与传统的频域诊断方法的比较，揭示出齿轮振动中存在的明显的非线性与非平稳特征，说明了不加选择地利用频域分析方法进行齿轮故障诊断很可能会得到错误的诊断结果；提出了一种轴承故障诊断的新方法，该方法利用ATVFD分解与Hilbert变换进行包络解调，并对解调得到的包络信号进行时频域分析，可以实现更加准确轴承故障诊断，说明了故障对载波信号的调制往往也是非平稳与非线性的；提出了一种利用振动信号进行柴油机汽缸内压力检测的新方法，柴油机汽缸压力的变化是柴油机故障诊断的重要参数，利用振动方法可大大简化汽缸压力的检测过程，该方法也是综合利用ATVFD分解与时频域分析方法实现的。

This article considers that the pre-schooler special-purpose school bus market potential is huge, after the analysis of the present situation of pre-schooler education in our country and pre-schooler school bus accidents in partial provinces and cities during 2005～2007. The security situation of school buses is unoptimistic. From the perspective of security, the complete form of the pre-schooler special-purpose school bus is reqestted on the basic of study of the school buses security measure in home and abroad. According to the statistical analysis of the human body size related to 3～6 year-old pre-schooler, the child chair's 6 main parameters, the passenger gate steps, and arm rest's size, as well as crossing control arm's mounting height and performance requirement have been determined. According to the present domestic and outside related standards to exports to the bus and school bus, the least quantities and most light-sized of the exports of school bus are proposed. According to the present domestic and outside standards to the request of driver's field of vision of bus and school bus, the essential requirements and inspection procedure of the field of vision of the pre-schooler special-purpose school bus are setted.

The endometrial echo patterns visualized sonographically were divided into three categories by Gonen: pattern A: present a triple-line pattern or multilayered endometrium in which hyperechogenic outer lines and a well-defined central echogenic line were visualized, with hypoechogenic or black areas seen between lines; pattern B: present an echo pattern in which the endometrium had the same echogenicity as the myometrium, the central echogenic line is dim; pattern C: present a homogenous endometrium with no central echogenic line.

按照Goden等人的分型标准，晚滤泡期子宫内膜在超声下可以分为三种类型：A型：即三线型，为外层及中部强回声，外层与宫腔中线之间为低回声区或暗区，宫腔中线回声明显；B型：为均一的中等强回声，宫腔中线回声不明显；C型：为均质强回声，无宫腔中线回声。
