Solve this problem, the best way is to turn valve stem with a tour, or rotary type control valve, and its thick stem stroke than a straight stem 2 to 3 times, and use long life of the graphite packing, valve stem stiffness Good, filling long life, but its friction torque is small, poor little back.

解决这个问题，最好的办法就是用旅转阀阀杆，即角行程类的调节阀，它的阀杆比直行程阀杆粗2～3倍，且选用寿命长的石墨填料，阀杆刚度好，填料寿命长，其摩擦力矩反而小、回差小。

To solve this problem, the best way is to turn valve stem with the brigade, namely, the class trip valve angle, and its stem stroke than the straight stem crude 2 ~ 3 times, and the selection of long-lived graphite packing, valve stem stiffness Well, filling long life, but its friction torque is small, a small hysteresis.

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.

根据采用先进施药技术的要求，本研究的设计内容主要有：⑴采用气液两相流喷雾技术，基于气力雾化原理，设计双流体喷头；⑵采用辅助气流输送雾滴，气流源为风机，对风机进行设计、选型；⑶为满足不同作物、不同栽培情况及提高雾滴分布均匀性、沉积性的施药要求，设计能带动喷射部件在一定角度内、以一定转速的旋转摇摆机构，本研究选用调速电机调节其摇摆速度，并利用反向行程开关调节其摇摆角度；⑷为满足不同高度作物、不同射程的施药要求，设计能调节喷射部件高度的升降机构，这里选用气缸为主要构件，既可以起到整机支架的作用，又可方便进行升降、固定控制；⑸设计行程开关的控制电路以及整机的控制系统。

It is like a huge two-stroke engine, with a capacity of 45 million litres, a stroke of 3 kilometres, and a frequency of one revolution per hour, says Edmonds.

"就像一个巨大的，4500万公升的二行程引擎，一个行程3公里，一个小时一往复。"埃德蒙说。

On these two days after came back from Hong Kong, the hiking always occurred to me, even in my dream, the unnumbered steps occurred, so I was reminded of writing down to record the journey.

从香港回来这两天脑海里还时时浮现这段行程，甚至梦里出现的也是那数不清的阶梯，提醒着我应该有文字来记录这段令人回味的行程。

The high-degree integrated traditional political culture of China was strongly impacted by the western powerful culture in modem times and caused its adjustments, so the historical journey of Chinese traditional political culture was displayed as the course of the nativistic movement. The history logic from 1840 to 1901 suggests that the crisis of Chinese traditional political culture in modern times be unprecedented and it could not be saved unless it should be replaced by a completely-new cultural form through the nativistic movement.

具有高度整合性的中国传统政治文化在近代遭遇了西方强势文化的冲击并由此展开了顽强抵抗和回应性调整，因此中国传统政治文化的近代行程表现为本土运动的历史行程。1840—1901年间中国传统政治文化本土运动的历史逻辑表明：中国传统政治文化在近代遭遇的危机是空前和全面的整体性危机，非本土运动所能自救，最终不得不进行全面的革故鼎新，以一种新的政治文化替代之。
