查询词典 vector density

Sixty-nine years ago today, a ghost word was outed from its hiding place on page 771 of Webster's New International Dictionary, where it had spent five comfortable years. Dord started life on a slip of paper prepared by the lexicon's chemistry editor, who noted that "D or d" was an abbreviation for density. A serendipitous misinterpretation saw the entry being read as a single word, dord, and it was accordingly registered and printed up as a noun with the meaning "density." No proofreader caught the error, but five years later an editor noticed the word had no etymology and began the investigation that led to the word's being banished.

六十九年前的今天，一个谜一样的词被世人发现，这个词在韦伯斯特新国际字典的771页整整藏了5年Dord一词因为一张小纸片而开始了它的生涯，这张小纸片是由lexicon的化学主编准备的，他标注出了"D or d"是密度的缩写这条记录很偶然的被认为是一个完整的单词，dord之后它被作为一个名词收入词典并印刷出来，意思是"密度"所有的校对人员都没有发现这个错误，但是五年后，一名编辑注意到这个词没有词源，然后他开始溯源并最终将这个词从词典中去除

Of the 89 patients, 59 had columnar metaplasia with goblet cells, which were further separated into low-density goblet cell and high-density goblet cell groups based on the percentage of crypts with goblet cells, and 30 patients had columnar metaplasia of the esophagus without goblet cells.

Accurate measurement of static magnetic parameter of high-density hard-disk media is vital for research and development of high-density hard-disk.

高密度硬盘介质静态磁性参数的精确测量对研制高密度硬盘至关重要。

The image showed that the ratio of raw material of RPC and particle distribution accorded with maximum packing density theory, and the porosity of accumulation was the least. The DSC showed the reaction rate of RPC was very fast and main hydration process focused in shorter time; SEM and X-ray showed that structure of the harden body of RPC was much denser, which mainly composed of some abnormal flat grains that got maximum packing density, and hydration products were mostly composed of Ⅲ type C-SH gel and a small amount of Ca2 and no AFt crystal.

由图象分析可知，即C原材料的比例及颗粒度符合密实堆积原理，堆积物的孔隙率达到最小；差示扫描量热分析表明，RPC的水化反应速度很快，主要的水化过程集中在较短时间内；扫描电镜及X衍射试验表明，RPC硬化体的结构非常致密，主要由一些不规则状的扁平粒子紧密堆积在一起，水化产物主要是Ⅲ型C-S-H， Ca2晶体的量稀少且没有钙矶石。

Objective To study the effect of helical CT scanning dose and slice thickness on lung density, and to determine whether the lung density value measured by standard dose helical CT scan can be used for low dose helical CT scan.

目的 探讨螺旋CT扫描剂量、层厚是否对肺密度有影响，以决定常规剂量螺旋CT扫描测得的肺密度值能否适用于低剂量螺旋CT。

No significant effects were observed at 30 Gy, but the hemopoietic organs capacity was disrupted at 50~300 Gy. The hemocyte density of the larvae irradiated at different developmental stages showed suppressed increments, and carbon-ion irradiation given to the larvae at early stages compared to the later stages had a significant suppressive effect on the hemocyte density.

结果表明 30 Gy 照射对造血器官的造血机能没有明显的影响， 50 Gy 照射能引起造血器官的机能低下， 50 ～ 300 Gy 之间没有明显的剂量依存关系；不同发育阶段幼虫的造血器官表现为随着个体的发育对重离子射线的感受性降低，雌雄间没有明显的性别差异。
