查询词典 difference

Data pre-processing technologies such as singular points elimination, registration and radius compensation are studied. Base on chord high difference algorithm, a new one called chord high difference-ratio algorithm is proposed to improve veracity and robusticity of singular points elimination. Then, a registration algorithm based on local surface reconstruction is proposed, which avoids infaust influence coming from single reference point error.

As a differential detection is used between the intercarrier, the proposed algorithm overcome the high sensitivity to timing error of conventional algorithm and is robust to multi-path. The effect of sample frequency offset can't be ignored in a continuous OFDM system of a large number of subcarriers. The estimation precision of the conventional algorithm is low and the realization is complex. A joint estimation of sample frequency offset and fine frequency offset based on difference operation is proposed. As averaging use a large number of samples in a maximum likelihood algorithm, the estimation precision is very high. The use of difference operation cancel the effect of carrier frequency offset, and the proposed sampling frequency estimation algorithm is robust to carrier frequency offset.

最后，本文对连续系统中的采样频率和载波频率精同步技术进行较为深入的研究，由于子载波数目大的连续OFDM传输系统中，采样频率偏差不可忽视，以往的采样频率估计方法精度低、实现复杂，因此本文提出了一种基于差分处理的采样频率偏差和精载波频率偏差联合估计算法，利用了最大似然算法进行采样频率偏差的估计，由于采用了差分处理方法，消除了载波频率偏差对采样频率偏差估计的影响，采用的最大似然算法对大量样点进行平均化处理，所以，相对以往算法，提出的联合算法估计精度高，而且采样频率偏差估计对载波频率偏差具有鲁棒性。

The anteroposterior projectionof the foot, utilized to examine the foot disease in the past was referred as to the freely-stressed method. However, most of the patients on suspicion of Hallux Valgus get pains while standing with weight-bearing. Additionally, the patients' real conditions can not be diagnosed without standing. it is helpful for us to apply both the foot weight-bearing and the foot non weight-bearing so as to probe the individual difference between the HVA and the IMA 1(superscript * intermetatarsal angle and further to provide the informative resources concerning the assessment of performing surgery operation. The study include 40 patients who we having Hallux Valgus of different degree, The findings have revealed the significant difference among 40 patients after the method-weight-bearing AP of the foot projection given.

过去一般常用诊断足部疾病的足部摄影(anteroposterior projection of the foot； AP projection of the foot)是指未施加压於病人足部的拍摄方法，然而多大脚趾外翻的病患常於站负重时感觉疼痛舒服，而未负重摄影却无法呈现出病人站时的真实态，因此我们用足部前后位负重摄影(weight-bearing AP projection of the foot)与足部未负重摄影(non weight-bearing AP projection of the foot)的影像比较其大脚趾外翻角(Hallux valgus angle， HVA)及第一跖骨间的角1(上标 st intermetatarsal angle， IMA的差，进而提供外科手术的估评。

Make a difference!Recently,I am a little down and lazy,maybe because of the cold weather,but I know it's myself that can't cheer up!Have hung around on the net,I found others' loves so vivid and rich,and I waked up.being not perserving is my shortcoming,but I mustn't make it my deadliness.No matter how,it's time to make a difference and hold on.Time is limited !!I have decided to take the interprater test grade3 and translater test grade2,hoping these certificates can help finding a good job.It's a hard way,but I will insist,I promise.

今年商务专业一个都没有被招走，有经济危机的缘故，也有自身素质不够高的缘故，xue和ling选择了大改，给自己多选了一条后路，我最开始本来也打算报名的，但后来再三考虑还是放弃了，万一到时还是应聘不上，既浪费了钱也浪费了精力，还有大半年的时间，我还有时间好好充实自己，只要自己有能力，哪里又找不到工作呢，经济危机说不定既是挑战也是机遇！
