According to the request of adopting advanced technology, the main designing has such contents as below:⑴ Designing the two-fluid nozzle that is based on the theory of air-atomize spraying.⑵ Designing and choosing the type of the axial fan that is used to supply assisted airflow to waft droplets that comes from nozzle.⑶ Designing the swaying outfit that can rotate the spray assembly at a speed and inside a angle in order to satisfy the spray request of different crops, different planting states and improve the uniformity of distribution, the deposition of droplet. Here, we select TYV type reduction gear motor to adjust the swaying speed and use course switch to adjust the swaying angle.⑷ Designing the lift outfit that can adjust the height of the spray assembly to satisfy the request of the crops of different tallness, different spraying range. Here, we select cylinder as the main component that can be used as kickstand and controlled easily.⑸ Designing the switch of the power supply that is put out of the greenhouse in order to prevent worker from poisoning. After the mist sprayer being made, the experiment is made to test the function of the greenhouse mist sprayer fully.

However, it is preferred that the terminal edge 30b of outlet channel 30a is in facing engagement with the inner surface in registry with a peripheral edge of the louvered vent 16a to urge air directly out of the air outlet 16 from the housing 12 to improve airflow through the airflow path.

然而，优选地，出口通道30a的终结边30b与内表面相接合，并与百叶式通风口16a的外围边配准，以便推动空气直接从外壳12经空气出口16流出，从而改善经过气流通路的空气流。

Airflow from the transom window takes a big share in overall greenhouse ventilation, and it extends to most area, especially the upper part and most of the down part of the greenhouse. More airflow concentrates around lean-to transom window areas, while the overall airflow is comparatively even.

顶窗通风量占整个温室通风的比例较大，从顶窗进入的气流遍及几乎整个温室上部和大部分下部空间，气流运动在顶窗开向侧比较集中，但总体运动比较均匀。

A subject was selected strictly from 30 healthy young people through nasal endoscopic examination, acoustic rhinometry measurement and CT scanning. Based on the CT image data of the subject, digital model of normal nasal cavity was reconstructed through Fluent 6.1.22 software. At the same time, according to the surgical requirements of FESS (remove the uncinate process and open the ethmoid sinus, maxillary sinus, and sphenoid sinus), post-FESS digital nasal cavity model was simulated. The viscous motion of nasal airflow before and after FESS was calculated by Navier-Stokes equations to compare the differences of airflow velocity, distribution, and pressure.

从30例健康青年人中，通过鼻内镜、鼻声反射测定仪及CT检查，严格筛选出一例研究对象，根据该入选对象的鼻腔CT影像资料，利用Fluent 6.1.22软件重建出正常鼻腔的数字模型，同时根据功能性鼻窦内镜手术的要求（切除钩突，开放筛窦、上颌窦和蝶窦）模拟出鼻内镜术后的鼻腔数字模型，再用Navier-Stokes方程对手术前后鼻腔气流的粘性运动进行数值计算，比较内镜手术前后鼻腔的气流速度、分布和压力的差异。
