查询词典 above ground

The effects of ground on trimming and maneuvering control were studied.Taking a typical helicopter as an example,the trims for steady flight with different velocities and altitudes were first solved.Then control laws for lateral jink maneuver were obtained for helicopter NOE flight.The calculation results conform to the ground effect theory,and load factor and control variation of the maneuver can be used for reference.

以某直升机为算例，在近地飞行和考虑不同速度与高度时，分别进行了直升机稳定飞行时的配平计算，然后以侧向紧急转弯机动为例，对机动操纵规律的问题进行了计算分析，计算结果与地面效应的理论相符合，机动过载和操纵变化规律可以为飞行试验提供借鉴。

Among the snake predators, Taiwan tree snake, Taiwan kukri snake and Pointed- scaled pitviper were responsible for most predation events. While the shrub nests were more susceptible to birds and Formosan Macaque, the ground nests were often predated by the ground-dwelling Crabeating mongoose and Formosan gemfaced civet.

与地面巢(71.4%)的共同主要掠食者，又以大头蛇、赤背松柏根与龟壳花最为常见；灌丛巢的次要掠食者为鸟类与台湾猕猴，地面巢则是须面对食蟹獴与白鼻心等在地面活动的哺乳类天敌。

It is not reasonable that striking distances of lightning leader to phase conductor, ground line and the ground are equal in classical electric geometry method.

针对经典电气几何模型认为雷电先导对导线、避雷线、大地三者之间击距相等的不合理问题，提出了用击距系数来描述雷电先导对导线与大地击穿强度的差别；依据长间隙放电与雷击放电的相似性，开展了棒-板间隙实验以得到击中目的物概率为50%时雷电先导与地面、导线之间的位置关系。

Radar data assimilation had a obviously improved effect on the mesoscale system in ground of squall line, especially in the previous 2-3 hours, which made the ground thunderstorm high pressure of simulation and wind field closer to the observation.

雷达资料同化对飑线地面中尺度系统的模拟有明显的改进作用，尤其是在前23 h效果非常明显，使模拟的地面雷暴高压和风场更接近实况。

In this paper the stress analysis solution of parallel circular tunnels in elastic ground under any coefficient of lateral pressure is derived, and the stress field and displacement field of parallel circular opening subjected to continuous boundary stresses are first solved, and then the ground pressure and the internal force in lining are obtained, using the displacement compatibility equation between linin...

先求得连续洞周边界应力条件下双圆形洞室的应力场和位移场；再利用衬砌和围岩界面位移协调方程，获得平行圆形隧道的地层压力和衬砌内力公式，并可考虑开挖面的三维效应和洞室自由位移等因素。根据结论公式，对隧道间距、地层性质、衬砌厚度等诸因素进行了讨论，得到了单因素的一般规律，在此基础上，提出了平行圆形隧道最小间距的近似方法，并在某工程中予以应用，得到了满意的结果。本应力分析方法在平行圆形隧道的设计和施工中供作参考。

Healtheries premium grade Ground Linseed is ground from the species of flax seed Linum usitatissimum.

亚麻籽是由上等地亚麻种子制成地亚麻粉。

In china, the research on ground stone tools focused on pre-historical stone typology, and then used the conclusion to study the communication and the influence between different cultural communities. The research on technology and function of the ground stone tools still is in the preliminary stages. Some issues, such as lithic resource, theories and the methods have not been set up.

我国关于磨制石器的研究，主要集中于史前石器类型学上的考察，进而研究文化群之间的相互影响与交流；关于制作工艺、工具用途等研究尚处于起步阶段，产地研究等还是空白，理论和方法尚未建立；学者多注重个案并非石器组合的研究。

Minimum ground clearance: the length from the low-water mark to the ground while full loading.

最小离地间隙：汽车满载时，最低点至地面的距离。

What frost points to is air temperature falls to when 0 ℃ are the following, the white ice crystal that the lunt in close ground air condenses on the ground or upper object, also call " of " Bai Shuang.

霜指的是气温降至0℃以下时，近地面空气中的水汽在地面或地表物体上凝聚成的白色冰晶，也称为"白霜"。

Contemporary artificial rainfall is artificial rainfall basically is principle of basis nature rainfall, launch activator from the ground through the plane is spread or using tall artillery piece, rocket, wait like silver iodide, dry ice, liquid nitrogen, drop cloud layer temperature thereby, form supersaturation lunt; to perhaps condense to the boardcast sowing in the cloud layer that contains supersaturation lunt nucleus, increase the ice crystal amount in the cloud, increase the amount of drip-drop and diameter then, raise cloud precipitation change rate, achieve the goal that raises precipitation of bureau ground nature thereby.

二、现代的人工降雨人工降雨主要是依据自然降雨原理，通过飞机播撒或利用高炮、火箭从地面上发射催化剂，如碘化银、干冰、液氮等，从而降低云层温度，形成过饱和水汽；或者向含有过饱和水汽的云层中撒播凝聚核，增加云中的冰晶数量，进而增加雨滴的数量和直径，提高云降水的转化率，从而达到增加局地自然降水的目的。
