Because chronic obstructive inflammation of airway severely influences the ventilation and exchange function of COPD patients, The motor ability of patients is limited .Despnoea and fatigue limit patients to sedentary,because of this, skeletal muscle began to analosis,oxygen uptaking capacity of skeletal muscle descends,and concentration of chondriosome degrades.Function limitation of skeletal muscle causes oxygen needs increase,so vicious cycle emerges,and further to restrict patient's respiratory and motor function.
由于气道的慢性炎症性阻塞,严重影响了慢阻肺患者的通气及换气功能,使得患者的运动能力明显受限,因喘息和疲劳而限制了患者的运动能力,使患者出现久坐,由此出现骨骼肌的萎缩,骨骼肌摄氧能力下降,线粒体氧浓度降低,骨骼肌的功能受限又会引起通气量不足,进而引起低氧血症和高碳酸血症,使患者的摄氧需求增加,由此出现恶性循环,进一步制约了患者的呼吸和运动功能。2001年正式提出肺康复作为中重度COPD患者稳定期非药物治疗的首选管理方案。

A series of internal documents from the late 1970s and early 1980s shows that BAT at least thought about applying this knowledge to cigarette design. A research report from 1979 puts it thus: There are three major design features which can be used either individuallyorin combination to manipulate delivery levels; filtration, paper permeability, and filter-tip ventilation. A conference paper from 1983 says, The challenge would be to reduce the mainstream nicotine determined by standard smoking-machine measurement while increasing the amount that would actually be absorbed by the smoker. Another conference paper, from 1984, says:(5)We should strive to achieve this effect without appearing to have a cigarette that cheats the league table. Ideally it should appear to be no different from a normal cigarette...
英美公司上世纪70年代末、80年代初的一系列内部文献表明,该公司至少曾考虑过将这一知识用于卷烟设计。1979年的一份研究报告上这样说道:可分别或联合应用与设计有关的三个要素,即过滤、烟卷包装纸的通透性以及过滤嘴的通气效果,来控制焦油和尼古丁的释放水平。1983年一份会议论文也提到,关键在于,要在提高吸烟者尼古丁实际吸收量的同时,减少可被标准检测方法测定到的含量。1984年另一份会议论文说:我们应当努力达到这一效果并能在检测中蒙混过关。

This paper made a systematic research on Lonicerafulvotomentosa Hsu et S.C. Cheng, which grows well inkarst areas, from its biological characteristics, such asmorphology, growth and physiology. The main conclusions asfollows:(1)From the viewpoint of morphological anatomy, it hastypical xerophyte structures such as well-developed epidermisand tissues that transport water effectively, small leaf area,dense floss under the leaf surface, high stoma density, thesmall opening degree, thick cuticle, well-developed xylem andpalisade tissues, etc. The pollen of L. fulvotomentosa isseems to be spherical, and has 3 grooves, much bulge on theepidermis evenly. The shape of pollen is an important featureon taxonomy. The ripe fruit has from 1 to 18 seeds, some fruitbranch has 135 berry, its diameter is up to 0.8 centimeter.(2)From the viewpoint of growth, L.

The most heavy flow ability of barrage swirl is controlled by fastenning device and barrage size, the most heavy discharge is more when barrage aperture is bigger, the influence of barrage position on discharge is not obvious; The pressure of the end of the shaft and fastenning device increases which aroused by barrage, and there is a restraining action to flow waving of the shaft; The barrage aperture is smaller, the increase of pressure is heavier, the influence of position to the increase of pressure is not obvious; The positive pressure of the level section in the hole between fastenning device and barrage increases obviously, the change of press along length reduces, mural press in the hydrosphere separating area of outlet of fastenning device becomes positive pressure, which is propitious to the increase of flow cavitate number in the low pressure area of the outlet of fastenning device; The influence of change of swirl cavum diameter caused by barrage to ventilating state is obvious.
阻塞旋流最大泄流能力由起旋器及阻塞体型共同控制,降低了泄洪洞的泄流量,孔径大的阻塞最大下泄流量较大,阻塞位置对泄流量的影响不明显;阻塞引起竖井及起旋器端头压力增大,对竖井部分的水流波动具有抑制作用;阻塞孔径越小,压力增加越大,位置对压力增大影响不明显;起旋器与阻塞之间水平洞段的止压力明显增加,沿程压力变化减小,起旋器出口的水气分离区壁面压力变为正压力,有利于起旋器出口低压区水流空化数的提高;阻塞引起的旋流空腔直径变化对通气状态产生明显影响。
