Two instantaneous Doppler estimation methods of wideband echoes based on Wigner-Ville Distribution ( RND ), a typical Time-Frequency Analysis method , are presented .
研究了基于Wigner-Ville分布的宽带回波瞬时多普勒估计方法。
Before the Rnd () function can be called , a call to the Randomize procedure must be made to initialize the random number generator .
调用Rnd()前,必须先调用Randomize过程以初始化随机数字生成器。
This article made an analytical study from5191 cases of students from colleges rnd secondary schools for professional training in Xining with bad eyesight and rtochoma .
本文分析讨论了西宁市大中专5191名学生视力不良及眼沙状况。
When life coming to an rnd , not necessarily disappear without trace , and sometimes it will be transformed into another form exists or regeneration .
当生活要清,不一定消失得无影无踪,有时它会被转化成另一种形式存在或再生。
To get a value within this range , you can multiply the result from the Rnd () function by10000 and discard anything after the decimal point .
要在这个范围内获取一个值,把Rnd()函数的结果乘以10000,并且去掉小数点后面的所有值。
The size of positive neck nodes is the key risk factor in determining the development of cervical recurrence in patients of advanced cervical nodal metastases after RND .
转移颈淋巴结大小是全颈清扫术后颈部复发根本和决定性影响因素。
The size of positive neck nodes is the key risk factor in determining the development of cervical recurrence in patients of advanced cervical nodal metastases after RND .
Methods One hundred and twelve patients with N2 , N3 head and neck cancer were treated by RND were retrospectively reviewed and the pathological specimen were restudied .
Conclusion RND can cause variable degree of disability in the shoulder which influences patients quality of life directly , self evaluation and abducting arm beyond 90 ° are good standards for evaluating shoulder syndrome .
