着陆

Some safely landing region in vision field can be recognized by image processing and the region character can also be recognized.

当前，由于着陆时定点的误差较大，在小范围安全地域准确着陆很难。

The landing party was certain that the SDF-7's arrival in Garudaspace had not gone undetected by the Invid; the shuttle landing would probably be monitored as well.

着陆队能肯定SDF-7到达嘎鲁达空间时已经被因维人探测到；穿梭机着陆也可能会被监视。

CAAC flight into nearly landing stage is flying high rates of accident, landing stage before 8 minutes and departure for 3 minutes, known as the highest rate of black 11 minutes.

民航飞行旳进近着陆阶段是飞行事故的高发阶段，着陆前的8分钟与起飞3分钟因事故率最高，被称为黑色的11分钟。

The military aircraft circled over the landing strip for some time before it landed.

They require high landing and takeoff speeds and long takeoff and landing runs, are unstable at high angles of attack, and produce tremendous drag when "trimmed" to keep the plane level.

他们需要高着陆和起飞速度和长期的起飞和着陆运行，不稳定，在高攻角，并产生了巨大的阻力时，"裁剪"，以保持飞机的水平。

In this paper,an optimum trajectory from perilune to lunar surface is derived in terms of Pontryagin's maximum principle,which is an open-loop way.Then,an optimal nonlinear control law based on an fuzzy neural network is presented,on the basis of the optimum trajectory,due to the nonlinear mapping function of the fuzzy neural network,which is a closed-loop way.

本文根据终端着陆条件和性能指标，以由Pontryagin's极大值原理得出从近月点到月球表面的最优着陆轨迹为基础，给出一种基于模糊神经网络的非线性最优控制策略，使被控系统能够通过模糊神经网络的非线性映射能力实现某种最优的闭环制导控制。

Basically,an optimal nonlinear control law based on an artificial neural network is presented,on the basis of the optimum trajectory from perilune to lunar surface in terms of Pontryagin's maximum principle according to the terminal boundary conditions and performance index.

其主要内容是，根据终端着陆条件和性能指标，以由庞氏极大值原理得出从近月点到月面的最优着陆轨迹为基础，给出一种基于人工神经元网络的非线性最优控制策略，使被控系统能通过神经网络对非线性的映射能力实现某种最优的非线性控制。

The landing must be supersoft, made at a velocity of 18 miles or so an hour.

这次着陆一定是超级的软着陆，即着陆时的飞行速度在每小时 18 英里(约29公里)左右。

An exception to this can be found in the landing portion of the jump as long jumps can make landing in a controlled telemark position more difficult.

作为本可以在跳着陆部分可以作为发现在控制Telemark的位置着陆长跳转更加困难异常。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
