Astronomers have used telescopes on earth and in space to nail the precise position of a mysterious, dark object at the outer edge of our galaxy 天文学家利用地面和空间望远镜精确的定位了一个神秘的暗物体就在我们星系边缘。
The result of experiment shows that this algorithm can get ride of the affect of noise and the edges fused have precise position and intact contour 实验证明该算法抑制了噪声对边缘检测的干扰,获得的边缘轮廓完整、定位准确。
The confederation bridge actually consists of 65 separate sections which were each built on land and then moved into precise positions by a satellite-guided floating crane 同盟桥实际上是建立在土地上,然后以卫星指导流动起重机搬进准确位置的65单独部分组成。
Success or failure of ancient chinese teaching is determined not only by its precise positioning but also by a good fusion of the traditional and modern linguistic theories 摘要古代汉语课程教学的成败,不仅在于对其准确定位,更在于课程教学实施者能否将传统语言学与现代语言学理论善加结合。
Applying magnetic levitation technology, the stage is suspended on the trail of inverse " f ", thus the wear and tear is eliminated, linear motor non-contact drive makes precise position of stage 利用磁悬浮技术将工作台悬浮在倒f导轨上,消除了导轨的摩擦和磨损;直线电机无接触驱动实现了工作台的精密定位。
For example, it can be used to drag make-up and solar pressure cancellation of low orbit spacecraft, formation flying and precise positioning of small satellite, repos 同时,mpt也可用于低轨道(300500km)航天器的大气阻力补偿,星际航行航天器的主推进,以及星座和小型卫星的编队飞行和精确定位等,具有广阔的应用前景。
On the contrary, biology has catalogued many traits produced by point mutations ( changes at precise positions in an organism's dna ) ? bacterial resistance to antibiotics, for example 实情恰恰相反。在生物的dna上,某个特定位址发生的变化叫作点突变。生物学家已经发现许多点突变制造的性状,例如细菌对抗生素的耐受本领。
The procedure can not only resist the influence of outlying kinematic model errors, but also control the effects of measurement outliers . 9 . the precise velocity can be determined respectively with precise positioning results, receiver raw doppler measurements and carri 讨论了gps姿态测量中模糊度解算、姿态角解算等问题,并基于非专业姿态测量接收机,给出了gps姿态测量的初步结果。
Lifting scheme is being used to decomposition-reconstruction signal, noise is removed and the precise position of impact signal is keeped . the signal-noise rate is improved, the loss is low . the method is very easy, many fields can apply it 用提升格式的小波分解重构算法,对振动测试信号进行去噪处理,去除属于噪声的小波系数,保留属于信号的部分,改善测试信号的信噪比,减少信号损失。
As a new communication mode, the spread spectrum communications are widely used in military communication, distance finding and precise position, because of its well multiaddress access, lowly capture probability, the excellent performance of anti-interference and secrecy 扩频通信作为新型的通信方式,以其优良的多址接入、低截获概率特性、抗干扰特性和强保密性被广泛应用于军事通信、测距与精确定位。
