查询词典 shift

A key point in Short Time Fourier Transform is the choice of window function. Although rectangle window is regarded as the first choice because it's featured by integral harmonic to filter signals and by DC component, decaying DC component and frequency shift of signals cause great error to rectangle window STFT. In addition, transient signals contain rich information of faults, but the fixed time window of STFT fail to collect these information.

STFT 算法关键问题之一是窗函数的选择，矩形窗以滤除信号整数次谐波和直流分量的特点自然称为首选窗，但衰减直流分量和信号的频率偏移对矩形窗 STFT 造成了很大误差；其次，暂态信号中含有丰富的故障信息，傅立叶变换固定的频窗忽略了这些特征信息。

According to the position of encephalorrhagia,the quantity of hematoma, and to ventricular hematocele and center-line structure shift's existence or unexistence,the occurrence rates and case mor-talities of hypertension encephalorrhagia complicated by hemorrhage of digestive tract are respectively made comparisons among 179 patients with hypertension encephalorrhagia.

对179例高血压脑出血患者，按脑出血的部位、血肿量、有无脑室积血和中线结构移位，分别进行比较并发消化道出血的发生率和病死率。

The results show that:44 out of 179 cases are of HECHDT,and 37 out of 179 cases are of death; the occurrence rate of digestive tract hemorrhage resulted from the hemorrhage of cerebral basis segment complicated by ventricle hematocele is the highest,and the sequence of the occurrence rates resulted from other position is subarchnoid cavity,brainstem,cerebral lobes,cerebellum,and within cerebral basis segment's hemorrhage; the encephalorrhagia complicated by the hemorrhage of digestive tract is mainly related to the factors of ventricular hematocele,center-line structure shift,hematoma quantity etc,and its case mortality is relatively high.

结果表明：179例中并发消化道出血44例(24.6%)，死亡37例(20.7%)；消化道出血发生率以脑基底节区出血并脑室积血为最高(38.9%)，其次依序为蛛网膜下腔、脑干、脑叶、小脑和局限于脑基底节区出血；并发消化道出血的病死率为50%，无消化道出血的病死率为11.1%。脑出血并发消化道出血主要与出血溢入脑室、中线结构移位、血肿量大等因素有关，且病死率高。
