着陆

The main flight strip system is an important part of manned spacecraft project for callback the return modules and rescuing the astronaut in time, and the communication is the information pivot of it.

主着陆场系统是载人航天系统的一个重要组成部分，负责完成飞船有效载荷的回收和宇航员的快速搜救。通信系统是其信息中枢。

In the rescue situation system of the main flight strip, the communication data link between the vehicle and Beijing center is important for rescuing on time. It is related to the correct decisions of commanders.

摘 要：在主着陆场搜索态势系统中，车载系统与北京中心间的海事卫星通信数据链路的通断直接影响搜救的及时性和正确性，关系到各级指挥员对搜索态势的准确把握和及时决策。

In accordance with the foreign carrier aircraft of similar size and weight of the structure of the standard conditions to compare the situation of J -10, the estimated result is improved for carrier-based aircraft F -10 bound to a significant increase in structural weight, if it is flying by leaping jump slide deck and conventional way of blocking the landing, the F-10B of the carrier improved in structure to increase the weight of about 500 ~ 550 kg, if the front wheel traction with catapult catapult take-off, front landing gear strength and the increase in traction structure also further increased from 100 to 150 kg weight.

按照国外类似规格的舰载机的结构条件和重量标准来对比歼-10的情况，估算的结果是歼-10改进为舰载机必然要大幅度增加结构重量，如果是采用跃升甲板滑跃起飞和常规拦阻着陆的方式，歼-10B 的舰载改进型在结构重量上大约要增加500~550千克，如果采用弹射器利用前轮牵引弹射的起飞方式，前起落架强度提高和增加牵引结构还要再增加100~150千克重量。

That it is impossible to land a flying saucer without its being smashed by one.

以致于要想使飞碟在那里着陆而不被某颗粒子撞毁简直是不可能的。

On his forthcoming landing that moment, a bee flying over, cried:"idiot, do not land where it was flypaper!"

就在他即将着陆的那一刻，一只蜜蜂飞过来，大声说道："蠢货，不要降落在那里，那是捕蝇纸！"

I walked up the path, glancing at the windows to see if anyone was looking for me.

我一面在路上走着，一面注意着陆窗户，看看是否有人在找我。

Investigation of the game you are a glider landed at the landing zone...

这款游戏考察的是您将滑翔机降落在着陆区上的能力。

This implies that a large ground crew is necessary to handle the airship during takeoff and landing.

这意味着，大量地勤人员要正确处理飞艇在起飞和着陆。

The main advantage of this layout is that it eliminates the ground loop problem of the taildragger.

前三点起落架最大的优点是不会像后三点那样，着陆时容易打转。

But group mind seems to be a liability in the decisive moments of touchdown, where there is no room for averages.

但是，群体智慧在飞机着陆的决定性时刻似乎成了不利条件，这时不能有什么平均的想法。

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。
