潮气

Methods The tidal flow-volume loop and other parameters (the volume,flow rate and resistance) were measured in 1002 normal children,aged between 0～47 months.

潮气呼吸肺功能检测只需平静呼吸，适用于不能配合的小年龄儿童，目前缺乏大样本量的正常预计值，给正确评价带来了很大的困难。

Melting point 3410 ℃, boiling point 560 ℃, relative density of 1935, F the external electronic structure of 5d46s2, in the chemical reaction time is very easy to lose 1-6 electronic, but also can get 1-2 electronic, so oxidation number of 0,± 1,± 2, 3, 4 , 5 and 6, with 6 price of the most stable compounds, such as WO3 does not dissolve in water, the air will form in the tungsten trioxide thin protective layer of tungsten, tungsten with fluorine at room temperature, chemical combination, red hot when there is no moisture and Bromine iodide together, red hot when you can and water reaction WO3, at room temperature reaction of tungsten with aqua regia, but the hot concentrated hydrochloric acid and sulfuric acid can only be played with its weak response, but molten nitrate, nitrite, too Hydrogen peroxide, sulfur steam, steam and other phosphorus can play intense reaction, high temperature can not be carbon, boron and silicon reaction of binary compounds, widely used in industrial tungsten steel and tungsten carbide, pure tungsten filament is used to the system, and X-ray tube Tube heating components, semiconductor components can be prepared tungsten silicide, tungsten industrial production is white or black tungsten ore tungsten ore refining.

熔点3410℃，沸点560℃，相对密度1935，F外围电子结构为5d46s2，在化学反应时很容易丢掉1—6个电子，也能得到1—2个电子，所以氧化数为0、±1、±2、＋3、＋4、＋5和＋6，以＋6价化合物最稳定，如WO3不溶于水，空气中的钨会形成薄层三氧化钨保护层，钨能与氟在室温下化合，红热并无潮气时能与溴、碘化合，红热时还能和水反应生成WO3，室温下钨可与王水反应，但热的浓盐酸和硫酸只能与其起微弱反应，但对熔融的硝酸盐、亚硝酸盐、过氧化氢、硫蒸汽、磷蒸汽等能起激烈反应，高温下不能与碳、硼和硅反应生成二元化合物，工业上广泛使用钨钢和碳化钨，纯钨用来制灯丝、电子管和X射线管的发热元件，硅化钨可制半导体元件，钨工业生产是将白钨矿石或黑钨矿石精炼。

Numerical simulation for impact of velocity and annular space eccentricity on prop-carrying capability of foam fluid

目的通过对240例毛细支气管炎患儿的潮气流速容量曲线的测定，以探讨毛细支气管炎患儿气道阻力的变化规律。

Methods The tidal breath flow volume loop, passive expiration flow volume curve and functional residual capacity were performed in 611patients of respiratory system disease at sleeping, using Sensor Medics 2600 pediatric pulmonary function meter.

方法采用SensorMedics2600型小儿肺功能仪，对611例呼吸系统疾患婴幼儿进行睡眠时潮气呼吸流速容量环、被动呼气流速容量曲线检查，部分患儿进行功能残气量测定。结果611例患儿中检出肺功能异常者558例(91.32%)。

Its unique thermal barrier design keeps moisture from forming and infiltrating your insulated system while preventing thermal energy loss through exposed metal handles.

其独特的热障设计防止潮气的形成和入侵保温系统，防止热能通过暴露的金属手柄而流失。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
