查询词典 distance

This project also compared and discussed the research results of OBS and onshore-offshore experiments in nearby areas. The conclusion is that the active airgun source is equivalent to an earthquake of about magnitude 0.5, and the airgun signals can be detected at the maximum distance of only about 250 km, which is not enough for the study of deeper lithospheric structure below the crust. Furthermore, the onboard airgun source and MCS streamer are difficult to operate in the shallow water of reef and island areas.

本项目还分析对比了周边地区海底地震仪探测和海陆联合地震探测的研究成果，发现人工气枪震源约相当于0.5级的天然地震，其信号传播距离最远只有250 km左右，很难探测到地壳以下更深部的岩石圈结构特征，此外船载的气枪震源和多道电缆在岛礁区和浅水区很难开展工作。

於是她对别的孩子说，她是"生就"的，还说，如果不是生就的，那她就变也变不成。

Apartamentos-Hotel Avilla is located in downtown Mexico City, within walking distance of The Alameda Central.

酒店评核是由通过 venere.com 预订并入住过这酒店的宾客所写的。

The albedo, diameter, and distance of such objects together determine their brightness.

这种物体的反照率、直径和距离是决定其亮度的因素。

Off in the distance he could see the massive stone carving of an eagle at rest, peering alertly and confidently out at the world, which was his own home and the heart of his domain.

即使在这种严酷的环境里，他们也沉浸于飞行的快感之中。不远处，他能看到一个巨大的鹰形石质雕塑正自信的俯视着这个世界。

An algebraic B-spline curve fitting algorithm based on the signed distance field is proposed in this paper.

This paper studies the construction principle and main algebraic properties of AES S-box,points out the S-box has these characteristics that periods of affine transformed pair is 4,periods of iterative-output is less than 88,strict avalanche criterion distance is 432,the algebraic expression has only 9 items and so on.

研究了AES S盒的构造原理和主要代数性质，指出了AES S盒的仿射变换对周期为4，迭代输出周期不大于88，严格雪崩准则距离为432，代数表达式只有9项等。

Integrating trellis-coded modulation with threaded algebraic space–time block code, trellis-coded modulation space-time block code is presented, which has the advantage of full-diversity and small detection delay. Based on TCM pre-processing, the minimum distance between different codeword matrixes of the TCMST block code is maximized, so the average bit error rate of the TCMST block code is lower than that of the TAST block code at the same signal noise ratio.

TCMST分组码具有满发送分集度和检测延迟小等优点；由于采用了TCM预处理，使得不同TCMST分组码码字矩阵间的最小距离达到了最大化，因此在相同信噪比情况下，TCMST分组码具有比TAST分组码更低的平均误比特率。
