Successful tracheal intubation wasverified using the following criteria: 1 identification ofthe trachea and tracheal rings, 2 visualization of vocal cords,3 widening of glottis as the tracheal tube passes through,and 4 tracheal tube position above carina and demonstrationof movement of the chest wall visceroparietal pleural interface(i.e., sliding sign) after manual ventilation of the lungs.

成功的气管插管通过如下的标准证实：1）辨别气管和气管环，2）可见到声带，3）当气管导管置入时声门变宽，4）隆突上气管导管的位置以及手控通气时胸壁内脏壁胸膜界面的运动。

Through the experiment results, in different phonation model, analysis the properties of glottal vocal efficiency, vocal folds vibration, and voice source.

我们在对嗓音—呼吸系统进行自动分割与分段特征表达的目标指引下，建立了具有国内一流水平的嗓音声学实验室；从概念上对嗓音—呼吸系统重新划分，以声门为中心分别建立去耦合和弱耦合条件下的嗓音—呼吸系统和肺胸系统数学模型；采用离体犬喉作为声带振动的物理模型，对数学模型进行完善与证实；采用盲解卷技术在去耦合和弱耦合条件下，提取上下声道传递函数、嗓音源和发声效率，研究上下声道去耦合和弱耦合条件下不同发声方式与状态对发声效率的影响。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
