Before the teaching activity, students' misconceptions of "air" concept mainly be, the student thinks the air isn't a kind of material, so the air isn't condensability, don't occupying space, and can't speaking out air current can be become common practice with form, its cause was that: the basic concept for air's quality was wrong and students always conducted incorrect judgment due to the ambiguity of literate meanings.

本研究的结果发现：学童在教学活动之前，有关「空气」的迷思概念主要是，学童认为空气不是一种物质，所以空气不可压缩，不占有空间，并无法说出空气流动可以形成风；其成因是：气体基本性质概念错误和常因字义不清而下判断错误。

The invention discloses a measuring method for firing conclusion and gas flow rate in the process of liquid, gas fuel firing, which comprises the following steps: positing three points on fuel transmission pipe, air pipe and gas pipe, setting regular measuring device or sampling device, measuring the flue's element and flow rate of point 1, air element of point 2, and gas element of point 3, inputting the data of three points into computing unit, computing air flow rate Mair, gas flow rate Mgas and firing conclusionηB by the element of air, flue, and gas and flue flow rate Mburn.

本发明公开了一种液体、气体燃料燃烧过程中燃烧完全度和燃气流量的确定方法，步骤为：在燃料输送管道、空气管道和烟气管道上分别设置三测点，并安装常规的测量装置或取样装置；分别测量测点1的燃料成分和流量；测点2的空气成分；测点3的燃气成分；将三测点的测量数据输入计算单元；根据空气、燃料和燃气的成分以及燃料流量M burn ，计算空气流量M air 、燃气流量M gas 和燃烧完全度η B 。

Pressure governor valve is the use of a spring-loaded power and pressure balance theory, when the spring-loaded pressure less than atmospheric pressure and the valves closed when the pressure is greater than the spring-loaded rubber tubing stretch when the bottom of compressed air diaphragm, diaphragm the effort to promote diaphragm upward and left vavle seat blow the air flow of gas, this would piston shirking role in the pressure mobile, Selection will be emissions from valve seat, air compressors made by the then air into the gas valves and exhaust emissions is through the mouth into atmospheric air compressors idling.

调压阀的原理是利用了弹簧力与压力相平衡的原理，当弹簧的压力小于气压的时候阀关闭，当压力大于弹簧的弹力时候橡胶调压膜片下方的压缩空气对膜片的作用力，推动膜片向上拱曲离开阀座而使空气流入气腔，此时卸荷活塞在气压作用下移动，将排放阀门推离阀座，于是由空气压缩机充入气腔的空气便通过排放阀和排气口排入大气空气压缩机空转。

An original exhausted-air reclaiming technical method has been presented, that is to say, the discharging chamber's pressure-air is reclaimed into the air tank through the additory of the exhausted-air reclaiming control devices which can be considered as the mid-pressure air supply for reutilization in order to realize the aim to save energy.

论文提出了一种创新性的气缸排气能量回收技术途径：通过附加排气回收控制装置将气缸排气腔的有压空气回收到储气罐中，并作为中压空气源再利用，以实现节能。

Air cleaning: To enable±·removed without the air-conditioning, special cleaning agent directly injected into the evaporator of indoor unit and outdoor unit on the internal heat exchanger, through the physical chemosynthetic, about ten minutes to clear the dirt, with the exception of food sterilization, air purification, but also the restoration of air-conditioning refrigeration, heating efficiency, extend the service life of air-conditioning.

空调清洗：使用本品不需将空调拆下，直接将专用清洗剂喷入室内机蒸发器上和室外机换热器内部，通过物理化合作用，十分钟左右即可清除污垢，除味杀菌，净化空气，还可以恢复空调的制冷、制热效率，延长空调的使用寿命。

Meanwhile some detailed numerical researches are done on the influence to the aerodynamic field throughout changing magnitude of the primary air and the secondary air, adopting homocentric two tangential circles, tangentially-fired in number one and number three corner face-fired in number two and number four corner, changing the air distribution of the secondary air and the reverse swirl of upper secondary air, Which provide the theoretical basis for boiler design, optimal operation, renovation etc.
