Therefore , it is difficult to accomplish the task of mura inspection perfectly with traditional methods which merly employ the contrast and area of object as the features of mura 当某个区域内包含mura缺陷时,该区域内像素的灰度值会发生突变。但由于mura缺陷的面积都比较小,不会改变整个液晶屏灰度的总体变化趋势。
Granule dimension ( granularity ) is the main character of granule and the first index of powder material , when the granule become smaller , the performance of it and its material can break , it is called granule dimension effect 随着颗粒的细化(粒度变小) ,颗粒和材料(在某些粒度段位)性能会发生突变,即颗粒尺寸效应。
Traditional detection methods are time - consuming and laborious with low detection sensitivity . it is the advantages of dna chips that are quick , accurate and simultaneous viruses " detection with higher sensitivity 传统免疫检测方法难以检测潜伏期以及抗原表位发生突变的患者且灵敏度较低; pcr方法每次只能检测一种病毒,费时费力。
The result of nanoscratching modeling showed that the load on the sample and friction force increased linearly at the initial stage . the load on the sample and the friction force increased suddenly when the film hardened 纳米划痕实验的数值模拟表明, ti - dlc膜在压头划痕初始阶段,纵向载荷和摩擦力都呈线性缓慢增加,在某一点发生突变,这时膜发生了硬化。
So far , most bird flu cases in people have been caused through contact with infected poultry , but scientists are concerned the virus could mutate into a form more easily spread between humans , causing a pandemic 迄今为止,大多数的禽流感病例是通过接触病禽所产生的,但科学家们关心的是该病毒能够发生突变,使得更易在人与人之间传播,从而在全国范围内流行。
There is an evident decrease of the summer rainfall of north china from 1951 to 2000 . what ' s more , the summer rainfall clearly takes place a catastrophe around 1979 , there is much more rain before 1979 and less after 1979 1951 - 2000年华北夏季降水有明显的减少趋势,且在1979年发生突变, 1951 - 1979年华北夏季多雨,偏涝, 1979 - 2000年华北夏季少雨,偏旱。
The successful cloning of the arabidopsis thanliana mutuants of non - fertilization endosperm formation and their related genes has made it possible to compare the molecular mechanisms of non - fertilization endosperm initiation in regular and mutant plants 拟南芥胚乳自主发生突变体及相关基因的克隆,使人们可以研究和比较自然和突变植物胚乳自主发生的分子机制。
Because the data mutate on the position that is the edge , the normal curvature on some orientation changes from positive to negative . so it is thought whether some point is judged the edge - point by this character 由于边缘是图像上像素发生突变的位置,所以在图像曲面上某一方向的法曲率值会出现由正到负的变化,故此应用这个性质来判断曲面上某点是否为边缘点。
Then , if and when the mitochondrial dna gets mutated so that one or more of the 13 proteins are no longer being synthesised inside the mitochondria , it won ' t matter - - the mitochondria will be getting the same proteins from outside 那么,如果线粒体dna发生突变,以致13种蛋白质中的一种(或一种以上)不再在线粒体内被合成时,就没有什么关系了?线粒体将从外部得到相同的蛋白质。
As reported , it is about 96 % of rifampin - resistant mycobacterium tuberculosis clinical isolates which resulted from the rpob gene mutation , for which , several methods for rapid testing of rifampin - resistance have been developed 据报导,大于96的结核分枝杆菌临床分离株耐利福平都是由于rpob基因发生突变所致。目前,针对rpob基因突变已出现了很多利福平耐药性的快速检测方法。
