查询词典 level pole

According to the science report, as the environment pollution comes worse and worse, the discharge of CO2 is increasing, the temperature is increasing too. If it cannot be improved yet, at the middle age of this century, the iceberg and glacier of the Antarctica and the Arctic Pole will melt because of the "greenhouse effect", at that time, the sea level will rise and even submerge the land which we live on!

据科学家报道，由于现在环境污染严重，二氧化碳排放日益增加，地球气温逐年增高，如果还不得到改善，本世纪中叶，气温问题将引起南北极冰川融化，到时海平面会上升，甚至将淹没我们赖以生存的陆地！

The earliest clepsydra was a copper pot holding water with a small opening at the bottom and a pole with scales standing in the center. When the water dropped through the small hole, people determined time by the scale on the pole as the water level decreased.

最早的漏壶用一只铜壶盛水，壶底有一个小洞，壶中插一根刻有刻度的标杆，水从小洞滴出后，人们根据水位降低后标杆上的刻度来判断时间。

This paper develops a new design method of self-tuning pole placement controller. In this method, parameters of the controller can be directly obtained by a two level linear identifier. It is unnecessary to find the solutions of Diophantine Equation and identify the extra auxiliary parameters. At the same time, the effect of deterministic disturbances can be eliminated.

提出了一种极点配置自校正控制器的设计方法，这种方法用两级线性辨识器可直接获得控制器参数，无需求解Diophantine方程，也不需要辨识多余的辅助参数，而且可以消除确定扰动的影响。

The problem was that the water pump could not pump in a nine-story residential building, as result the water would soon be used up. I arrived at night; found that liquid level relay broke down. then I installed a three-pole knife switch next to liquid level relay to power the pump manually, so the problem with no water to be solved provisionally. then I fitted the Level relay for them, finally the water pump can pump automatically again

有一次来电，物管说他们小区没有电工，说一幢9层的住宅楼一楼的水泵泵不上水，水池很快就会无水用了，晚上我到达现场，原来是液位继电器坏了，我当时已带上了三极的闸刀开关，在继电器的旁边装上闸刀开关，手动供电给水泵，临时解决了没水用的问题，过后才为他装上液位继电器，又恢复了自动泵水。

"Each float contains a single pole mercury switch which actuates when the longitudinal axis of the float is horizontal, and deactuates when the liquid level falls 1"" below the activation level."

"Each float contains a single pole mercury switch which actuates when the longitudinal axis of the float is horizontal, and de actuates when the liquid level falls 1"" below the activation level."

每个浮控开关包含一个单极水银开关，当浮球的纵轴处于水平位置时，开关打开，当水位低于启动位置1英寸时，开关关闭。

"Each float contains a single pole mercury switch which actuate s when the longitudinal axis of the float is horizontal, and de actuate s when the liquid level falls 1"" below the activation level."

每个浮控开关包含一个单极水银开关，当浮球的纵轴处于水平位置时，开关打开，当水位低于启动位置1英寸时，开关关闭。

On the second level there is a platform with another sisal pole going up to the third level.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
