查询词典 The Beacon

A method to acquire and track the beacon for deep space optical communication system is proposed, which uses star as beacon, and controls the direction of down beam based on the absolute position in inertial frame, the ephemeris of aircraft and earth and the attitude of aircraft.

提出一种深空光通信系统的信标捕获、跟踪方案，该方案是以恒星作为信标，根据恒星在惯性坐标系中的绝对位置信息，基于航天器和地球星历表、航天器的姿态信息来进行下行光束瞄准方向的精确控制。

Dr. Langford's awards include the Best Paper at the International Business and Economic Researcher Conference and Teacher of the Year from Beacon Club UL.

Langford博士所获荣誉包括国际商业和经济研究会议最佳论文和Beacon俱乐部UL教师奖。

In this thesis, we present a new channel scan method called "random scan" to reduce the delay. The scheme divides the beacon interval into several sections. In each beacon interval, only one section will be scanned and it will take multiple beacon intervals to scan all the section to cover the entire beacon interval.

在本论文我们提出一个减少IEEE 802.11无线网路之漫游所造成服务中断的机制称为随机扫描，此机制将标记间隔切割成数个区段，在每个标记间隔中，只对一个区段进行扫描，剩下的时间可继续正常的传输，以降低服务被中断的时间。

The highest point of the hills is the Worcestershire Beacon at 425 meters.

Worcestershire Beacon是山体的最高点，海拔425米。

Methods A novel fluorogenic probe, TaqMan-Molecular Beacon, which combined the hairpin structure of molecular beacons and the cleavage mechanism of TaqMan probes,was developed. Combined with a real-time PCR instrument, TagMan-MB was used for quantification of templates of ancient DNA.

利用分子信标的茎环结构和TaqMan的降解作用设计一种新型的TaqMan-Molecular Beacon荧光检测探针，与实时PCR仪联用，对古DNA模板进行定量检测。

One disgusting canvas seemed to depict a vast cross-section of Beacon Hill, with ant-like armies of the mephitic monsters squeezing themselves through burrows that honeycombed the ground. Dances in the modern cemeteries were freely pictured, and another conception somehow shocked me more than all the rest -- a scene in an unknown vault, where scores of the beasts crowded about one who had a well-known Boston guidebook and was evidently reading aloud.

有些画的广度和深度令人叹为惊止：Beacon山好似被整个儿从当中切开，画家精心绘制了切面之内的场面——成百上千的怪物挤在山内的地洞里头，慢慢的向外蠕动，彷佛整座山就是一条肥硕的蛆虫，真是令人恶心；墓园魔舞依然是个常见的主题，只不过这次换成现代的墓地；还有个构思倒是把我震住了：在地窖内，几十个人不像人鬼不像鬼的东西围在一起指指点点，细细一看，当中一个居然拿着本著名的波士顿旅游指南，并且明显在大声朗读。

We were too late for the elevated, and walked back downtown through Hanover Street. I remember that wall. We switched from Tremont up Beacon, and Pickman left me at the corner of Joy, where I turned off. I never spoke to him again.

由于时间太晚，城铁停运了，我们只好顺着汉诺威街走回市中心——**路边那堵墙我还记得呢，然后从Beacon街转到Tremont街，Pickman最后在Joy街角和我分手，自始至终我都没和他说过一句话。

First of all, a station estimates the congestion condition periodically and piggybacks its congestion information within the transmission packets. After an AP receives the information, it has a complete picture of the channel utilization. Then it uses SyncScan mechanism to send the congestion information to the stations with the Beacon frame.

首先我们使用壅塞情况的预测，让所有的工作站周期性的侦测目前通道壅塞的状况，并且将目前侦测到的壅塞情况的资讯附加在封包中传送出去，在附近的AP收到这些讯息后，利用同步化扫描的方式，将它所收集到的通道的资讯附加在Beacon的封包中，当STA接收到Beacon后，会把通道资讯储存在比较表内。

To maximize the number of stations which contend the channel successfully, OPSM configures the traffic indication map fields in beacon frames to constrain collisions.

该机制以成功竞争到信道的站点个数最大化为目标，通过修改beacon帧中的业务指示表域限制过度竞争。

The equal distance 3-improved-coverage number of beacon sending position is presented according the acreage of ROI.Then a simple method is put forward to calculate the coordinates of the sending positions in rectangular ROI.Aiming at the shortage of the existent sequence algorithm,when beacon moves according to the path and emits RF signals at every position,the ant colony algorithm is applied to the position sequence so as to get the beacon sending position.Further,in this algorithm the sensors could work out their position with trilateration.

根据ROI面积给出了等距三重优化覆盖此ROI所需要的信标发射位置数量计算方法；随后对矩形ROI提出了一种简单的信标发射位置确定方法；针对现有的遍历发射位置点的路径遍历算法的不足，提出了一种新的应用蚁群算法的信标发射位置点的遍历算法，并利用该算法对基于三边测量方法进行传感器节点定位。

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。
