Rentrop grade was significantly related to PDCF, but a wide range of PDCF was observed in patients with Rentrop grade≤1. PDCF can predict left ventricular recovery after successful PCI, and evaluate the collateral flow mensurably with AMI.

Rentrop分级与压力源性的冠状动脉侧支血流分数呈正相关性，该冠状动脉侧支血流分数同30d后左室射血分数呈正相关性。

As a supplement of conventional CT, CT perfusion imaging can reveal the perfusion informations of tissue or organs, such as hemodynamics, microcirculation status. It is helpful not only in finding morphologic changes, but also in providing functional and metabolizable information about the circulation parameters of hepatic diseases. So, it is valid for studying liver disorders by providing functional information, especial for the differential diagnosis and assessment for therapeutic response.

作为常规CT的一种补充，它能提供组织器官微循环状况、血流动力学变化等其它灌注参数，对肝脏病变除了能显示解剖形态学改变，还能了解血流动力学状态等反映功能、代谢变化的信息，在肝脏疾病的影像诊断与鉴别诊断等方面具有重要的作用，特别是对各种治疗方法的疗效评估及监测具有指导意义。

The CDFI showed that the punctiform or strip color blood flow signal were found, which blood current spectrum were like the artery, envelope curves were not clear, monophase or bilateral low resistance.

CDFI 检查显示在囊实肿块内或周边见到点状或条状彩色血流信号，呈动脉样血流频谱，包络线不清楚，呈单相或双向低阻力，Vs为(50.05±5.02)cm/s， Vd为(23.20±4.45) cm/s，RI为(0.43±0.02)。

The features of ultrasound image of adrenal cortex carcinoma were 1The tumor was big,mainly isoechogenic,more than 8.2cm in diameter;2The tumor shape was varied,irreqular or multilobar;3Color Doppler showed plenty blood supply of the tumor and its surroundings and 4Tumor necrosis frequently seen.

1。肾上腺皮质腺癌的声像图特征为：①肿瘤是以等回声为主的较大肿瘤，本组均大于8.2cm；②肿瘤形态多样，以不规则形及分叶状常见；③彩色多普勒血流显示瘤内及瘤周血流丰富；④肿瘤内多见液化坏死。2。

Increased uterine contractions might decrease blood perfusion to the myometrium and endometrium, subsequently minimize the vascularization pattern.

子宫肌肉层的收缩会减少血流的供应，进而影响子宫内膜的血流情形。

Objective:to explore the evaluation of color doppler ultrasonography in differential diagnosis of renal cystic disease.methods:theultrasonographic finds of cystic renal cancer in 4 cases,renal cyst in 30 cases, renal tuberculosis in 3 cases,nephropyosis in 8 cases,renal hydatid in 2 cases were analyzed.compared with each other in size,shape,edge, echo of cyst wall and cyst water,intracapsular membrane,blood flood.results:two-dimensional and color ultrasonography are helpful in showing the characteristic of structure and blood flow.the signal of blood flow can be found in cystic wall.node of cystic wall and intracapsular membrane of cystic renal cancer.the rate ofintracapsular membrane and node of cystic wall is higher than nephropyosis,renal tuberculosis and cystic renal disease.

目的：探讨彩色多普勒超声在肾脏囊性病变鉴别诊断中的价值。方法：对临床和病理证实的4例囊性肾癌，8例肾脓肿，2例肾包虫，3例肾结核，30例肾囊肿的二维超声及彩色多普勒超声表现进行了分析，对每例病灶的大小、形态、边界、囊壁回声、囊液回声、囊内分隔及彩色血流的有无、性质进行比较。结果：二维超声和彩色多普勒超声可以反映肾脏囊性病变的结构特征及血流特征。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
