The slow progress of researches on pulmonary stem cells up to date has its root in the complex structure of pulmonary tissues and respiratory tracts, which is demonstrated by the facts that the respiratory system is composed of at least 40 types of cells, plus that the growth, renewal, and regeneration rate or capacity of respiratory epithelium are extremely limited. Mean while, there have been no specific stem cell markers for pulmonary and lung cancer, so researchers rely on stem cell markers borrowed from other systems to search for stem cells in pulmonary system.

Then, it studies the supply chain management system as a complex system to confirm the state existing during operating of the system. After that, it conducts a probability analysis on the state which the system located by applying supplement variable method, and establishes the model of distributed parameter system in a form of partial differential equations. Combining C0 ? semigroup theory in the functional analysis, it conducts a dynamic analysis on the established mathematical model. Using this method, it obtains the mathematical expression of the dynamic solution and the steady state solution, and proves the uniqueness, non-negativity and the asymptotic stability of the system solution. This dissertation applies the Matlab tool and uses two-step, three-step Simpson integral equation to imitate the condition of system solution. Then, it adds possible mode of failure and the optimization adjustment state to the system, based on which it has established the distributed parameter system model which is described by partial differential system of equations. Combining the functional analysis C0 ? semigroup theory, it studies the established mathematical model, and obtains the mathematical expression of the dynamic solution system and the steady state solution. It has proven the existing of uniqueness of the system solution, the asymptotic stability of system solution and the system solution. In addition, it has lying the theory rationale for further analysis and the research on the optimization of system.

Due to ozone can cause upper respiratory tract inflammation, injury terminal bronchiole epithelial cilia, thus weakening the defense of the upper respiratory tract, so long-term exposure to a certain concentration of ozone is also easy to secondary upper respiratory tract infection.

由于臭氧能引起上呼吸道炎症、损伤终末细支气管上皮纤毛，从而削弱了上呼吸道的防御功能，因此长期接触一定浓度的臭氧还易于继发上呼吸道感染。

Parents should pay special attention to whether the baby bronchiole issues, or whether there痰多caused by respiratory obstruction, and that leads to the causes of neonatal respiratory distress include: low birth weight, the mother has a history of diabetes, premature rupture of membranes, meconium pollution, birth mother irregular fetal heart tone, prolapsed umbilical cord, the fetus had cooked, prematurity, multiple births, chest, heart or respiratory abnormalities.

The principal of buffer is described as follows.At impulsing down,the piston moves down and vacates the annular space.The pressure in respiratory cavity decreases to a certain level and the traveling valve opens.At that time,the liquids enter into traveling valve and cavity and the plunger is impulsed upward to carry out the gentle transient at the sudden change.When the upward impulsing begins,the respiratory cavity is subjected to pressure and the traveling valve closes.During the gradual pressure rising,the liquids in respiratory cavity effuse from the upper ventage and the sudden change of force-summing direction of plunger is relieved relying on the resistance of ventage.

其原理大致是：下冲程时，活塞向下运动，让出环形空间的体积，呼吸腔内压力下降，下降到一定水平后，游动阀打开，此时，游动阀和小孔同时进液，使柱塞在从上死点处突然改变方向向上运动时得到缓冲，实现了柔和过渡；当上冲程开始时，呼吸腔受压，游动阀关闭，在压力逐渐上升的过程中，呼吸腔内的液体从上部的小孔流出，并依靠小孔的阻力使柱塞受力突然换向得到缓冲。
