查询词典 in contrast

Postoperative contrast sensitivity testing showed statistically significant differences (P＜0.05)between the two IOLs at 12 and 18 cpd under photopic, at 1.5and 3 cpd under mesopic, and at 1.5 and 3 cpd under mesopic with glare conditions.· CONCLUSION: The Tecnis Z9000 IOL proved to have statistically significant superior contrast sensitivity to the 911AIOL at high spatial frequencies under photopic conditions and at low spatial frequencies under mesopic and mesopic with glare conditions.

In this study, three cats were trained to perform monocularly a contrast detection task by two-alternative forced choice method. The perceptual ability of each cat improved remarkably with learning as indicated by a significantly increased contrast sensitivity to visual stimuli.

该研究用二选一(two-alternative forced choice)方法训练3只猫通过单眼进行对比度检测学习，发现每只猫对视觉刺激的对比敏感度随着训练而显著提高。

Mr. Zhang likes to utilize the contrast of two colors of bluish violet and nacarat in his paintings. Located in highland, Xinjiang's air is fresh. The hues between the areas directly illuminated by sunlight and those in shadow lighted up by skylight, produce an extremely strong contrast of bluish violet and nacarat.

张永旭在画面上喜欢使用蓝紫与桔红的对比，新疆地处高原，空气清新，阳光直射到的地方，和阴影中天光照射到地方，其色彩呈现出光学上蓝紫和桔红的对比十分强烈。

It was found that the incidence of As and Wd in the group of juvenile poliosis and the correspondence rate of A/A and L/W were obviously lower than those of the normal contrast group,while a-b TRC value in the female patients with juvenile poliosis and the incidence of abnormal palmprint in the male, the frequency of all loop whorl,and palm patterns in the I2 area of the right hand and in the Hyarea of the left hand were evidently higher than the corresponding incidences of the normal contrast group.

发现青少年白发组的As和Wd出现率以及A/A和L/W的对应频率均显著低于正常对照组；青少年白发组女性的a-bTRC值、男性变异型掌褶纹的出现率、10指同斗频率、右手Ⅰ2区及左手Hy区的花纹出现率均显著高于正常对照组的相应出现率。

On the other hand, we study the vertical alignment for a ferroelectric liquid crystal that has fast response, high contrast, and analog gray scale capability. In contrast to the conventional rubbing alignment in a planar geometry, smectic layers arrange themselves parallel to the substrates, and thus extremely uniform alignment of molecules in large area is naturally achieved.

此外，本论文也尝试把FLC做垂直配向，讨论其静态与动态光学现象，并观测其光学图样与模拟结果作一比较；FLC在垂直配向不同於水平配向会有缺陷的产生，所以会有很好的暗态表现，其暗态好坏与否与FLC材料的螺旋距和液晶盒的间隙有相当大的相依性。

Hume's should have rather poor supercilium/ crown contrast (as the supercilium should be off-white-buff rather than white) and have rather grey-black centres to coverts and tertials (offering reduced contrast with the mantle and also with the wing bars).

休氏柳莺应该有比较不明显的眉线/头侧线对比（因为眉线是略带皮黄色的白色而非白色），而且覆羽和三级飞羽中央是偏灰黑色，导致和背部与翼带的对比比较不明显。

Contrast enhanced ultrasound and CECT or CEMRI are not fully superimposable, as UCA remain in the intraascular space, whereas the majority of currently approed contrast agents for CT and MRI are rapidly cleared from the blood pool into the extracellular space.

造影增强超声和CECT或者CEMRI不是完全重叠的，因为UCA停留在血管内，而目前大多数经批准的CT和MRI的造影剂会从血池中快速清除，并进入到细胞外间隙。

Seven cases with portal vein tumor thrombus were diagnosed by CO2-hepatic arterio-sonography (CO2-HAS). Their ultrasonographic features of CO2-HAS were as follows: several seconds after the injection of CO2 microbubble contrast, bright cloudy flowing echoes or several flowing echo stripes along the long axis of portal vein were seen in tumor thrombus. During interrupted phase of CO2 contrast injection there were still scattered unflowing bright echoes in tumor thrombus.

应用二氧化碳(CO2)肝动脉造影诊断 7 例门静脉癌栓，其造影增强声像图表现为：注射CO2微泡造影剂数秒钟后即可见癌栓光团弥漫性光点闪动，似白云翻滚或门脉实体回声内有数条和门静脉管径长轴平行的微气泡光带流动，停止注射后门静脉实体回声内仍有弥漫性非流动性增强光点，持续时间较长。

中华超声影像学杂志/980401 摘要应用二氧化碳(CO2)肝动脉造影诊断 7 例门静脉癌栓，其造影增强声像图表现为：注射CO2微泡造影剂数秒钟后即可见癌栓光团弥漫性光点闪动，似白云翻滚或门脉实体回声内有数条和门静脉管径长轴平行的微气泡光带流动，停止注射后门静脉实体回声内仍有弥漫性非流动性增强光点，持续时间较长。

Results show this new-inlet hydrocyclone has original sides on liquid spin-making and stabilize its flow field. Moreover this gradual contraction inlet may translate some pressure energy of liquid into kinetic energy and increase circumrotate speed. These play active actions on improving separation efficiency. Moreover, the uniflow hydrocyclone has the traits of big capacity, low pressure drop and a little low separation efficiency in contrast to the returned flow hydrocyclone. This hydrocyclone system has the higher separation property in contrast to the single-level hydrocyclone.

实验结果表明：这种新型入口结构水力旋流器在流体的导旋方面具有独到之处，能很好的形成稳定的流场；同时这种渐缩式入口方式，可将来液的一部分压能逐渐转化为动能，提高了旋流速度，对提高分离效率起到积极作用；采用新型入口的直流式水力旋流器比返流式水力旋流器压降低，处理量大且分离效率略低；组成返流式水力旋流器串联系统相对于单级水力旋流器具有更高的分离性能。
