The detailed and thorough analyses of the four images of protagonists are carried out in the second section. They are respectivelyCarol in Main Street, a brave young bride who faces the cultural conflicts with enthusiasm of reformation, and whose dream is still alive waving despite the final return to the parochial Gopher Prairie; Babbitt in Babbitt, the typical "TBM", who is in nature a conformist and doomed to be bounded but tries to escape and finds only failure; Arrowsmith in Arrowsmith, a young medical scientist with grand dream and determination in truth-seeking; and Dodsworth in Dodsworth, a rich, generous, considerate, diligent and down-to-earth car producer.

然后详尽阐述各个人物形象的特点，依次是《大街》中的卡络，一个面对文化冲突勇敢应对，力求革新，虽重新回到狭隘闭塞的小镇，但仍怀有梦想的年轻女性；《巴壁德》中的巴壁德，一个虚伪固执，注定无法摆脱自身局限，却一定要尝试并以彻底的失败告终的房地产掮客；《亚罗史密斯》中的亚罗史密斯，一个怀有梦想并为之终身追求的最具英雄气质的年轻医生；及《道茨沃斯》中的道茨沃斯，一个富有，宽容，体贴，勤奋，脚踏实地，热爱生活的汽车生产商。

After analyzing the performance anduncertainty of the DDPM vortex flowmeter in gas-liquid bubble flows, the vortexflowmeter-Venturi tube combinative method using the vortex flowmeter and the Venturi tube as measuring cells was put forward, the measurement model based on thevortex frequency and the Venturi differential pressure was established, and it showsthat the relative errors of this method for the mass flow measurement of bubble flowsare within±5%. Furthermore, the flowrate and volume void fraction of bubble flowswere obtained using a single DDPM vortex flowmeter through the relationshipbetween the frequency and amplitude of the circumferential DDPM signal, and resultsdemonstrate that the relative errors of the flowrate and volume void fraction of bubbleflows are within±5% and±10% respectively, which indicates the broad applicabilityof this method to large numbers of engineering fields.

The shear layer vortices dominate in the initial portion of the jet, which are a result of the K-H instability. The crossflow encounters an adverse pressure gradient ahead of the jet and separates to form horseshoe vortices under the pressure downstream, and they develop into the wake. The wake vorticity comes into being in the actions of an adverse pressure gradient and a wall-normal component of vorticity, which originates from the wall boundary and is entrained into the jet. The shear layer vortices encounter adverse pressure gradients in the lee of the jet and break down, leading to the formation of the CVP and the CVP is the most important characteristic of the jet in crossflow.

文中指出：剪切层涡源于射流与横流之间的K-H不稳定性；马蹄形涡的产生是由于射流喷口上游迎风侧的壁面边界层内存在逆压梯度，使流动发生了分离，在下游逆压梯度的挤压作用下，形成了马蹄形涡，马蹄形涡向下游发展，进入尾迹区；在逆压梯度和法向涡生成项的共同作用下产生了尾迹涡，尾迹涡源于壁面边界层，止于射流，并将部分涡量向上输运至射流内部的CVP；CVP是横向紊动射流的重要特征，剪切层涡破裂后，在逆压梯度的作用下CVP形成。
