This essay will remark on auto air-condition noise problems through studying expansion valve. The main reasons incurred noise are two, one is vibration, which is from big air bubble caused by the refrigerant flows through expansion valve. Another is resonance, which is from engineering working itself. So, the two methods for eliminating noise are found. On one hand, through increasing damp to weaken resonance. On another hand, through taking off air bubble to eliminate vibration. The essay presents method of solving noise through improving expansion valve and elaborate the disadvantages caused by these solvement.

本文从膨胀阀的角度去考虑解决汽车空调异响问题，认为产生异响的主要原因是制冷剂流经膨胀阀节流部时有大气泡存在引起振动与汽车发动机共振造成，从增加阻尼块来减振和分解大气泡来消除震动等两方面提出解决方法，并对此方法造成的不利方面也进行了阐述。

It shows that the exhaust resistance at the wind blast end reduces obviously, driven by the 800mA/12V small scale draught fan, average exhausting speed reaching above 4m/s, fairly enough to satisfy the air conditioner's demand for new wind volume. Meanwhile, the conic section of the horizontal profile and the linear design of the longitudinal profile of the exhaust end inner cavity and wind shroud for each outlet greatly reduce the flowed out exhaust, effectively lowering the wind blowing feel of the air conditioner user by playing the function of air diffusion.

经过计算和实际测试表明，该装置的送风末端风口阻力明显减小，在800mA/12V小型风机驱动下，出口平均风速可达4m/s以上，足以满足空调对象的新风量要求；同时，横截面采用2次曲线型设计、纵截面采用流线型的送风末端内腔和出口均风罩使气流流出后风速迅速衰减，起到散流器的作用，有效降低了空调对象的吹风感。

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用途力，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用途下移动，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。

Medical expert is urgent the appeal as air conditioning gain ground, air conditioning already made the transmission medium of communication that catchs a disease, according to domestic statistic proof, annual the number that the summer has air conditioning disease and the contagious disease that spread by place of air conditioning channel is increasing, endangered the health of people badly, so, for the health of you and family, please us the place of easy oversight is cleaned clean thoroughly, especially the dirt of air conditioning interior and bacterium are the place that our consciousness is less than.

药学学者重要倡导随着空调的普及，空调已经变为感染病痛的传布途径，据境内统算证实，毎年夏天患空调病及由空调途径所传布的感染性病痛的人，数愈来愈多，严峻危及了大家的良好健康，故而，，为了阁下和家人的良好健康，请将咱们易于省略的地点根本冲冼清爽，特別是空调里面的尘士和病菌是咱们认识不到的地点。

When switching on the machine, the material is conveyed into the grading unit by the feeding devices. The material is separated into fine particle and coarse particle here, the qualified fine particle is released directly from the air pipe; the coarse particle enters the grinding chamber, grinded under high speed strike of the hitting block and then is transferred by the air pipe to the worm grading device. The satisfied particle is released with the exhaust air from the exhaust pipe and is collected as final product.

粉碎时，待粉碎物料由送料装置均匀送到分级室，在这里进行预先分级，原料中的合格颗粒经分级后从排气管排出，粗颗粒进入粉碎室，在冲击锤块的高速冲击和研磨作用下被粉碎，粉碎后的物料经进气管进入的上升气流作用下输送到蜗轮分级机进行先分级，合格颗粒经分级后从排气管随尾气一起排出后收集为产品，粗颗粒再次返回粉碎室继续粉碎。

Based on the results simulated by PRECIS (Providing Regional Climates for Impacts Studies), which is developed in the Hadley Centre for Climate Prediction and Research, changes of surface air temperature and precipitation under SRES B2 scenario in South China during 2071~2100 are analyzed. It is shown that, compared to baseline (1961~1990), surface air temperature in 2071~2100 would increase by 2~4℃, precipitation in summer would increase in the north part to 22°N, while the precipitation in winter would decrease in the whole areas of South China. The climate trend of the surface air temperature would be positive, however the climate trend of the precipitation would be negative, the occurrence frequency of extremely high temperature events and extremely heavy precipitation events would increase.

利用英国Hadley气候预测和研究中心的区域气候模式系统PRECIS，模拟分析基于政府间气候变化专门委员会 2000年发布的《排放情景特别报告》中设计的B2情景下华南区域2071~2100年的温度和降水量的可能变化，结果显示：2071~2100年均地面温度相对于气候基准时段（1961~1990年）上升约2~4℃；华南区域未来夏季降水量在22°N以北区域较气候基准时段增加，而以南区域减少；冬季降水则表现为华南区域较气候基准时段减少。2071~2100年华南区域的温度气候趋势系数为正值，年均降水气候趋势系数为负值。2071~2100年的高温事件和强降水事件的发生频率均比气候基准时段明显增加。
