a文献报道CT平扫一般为稍低密度、等密度或稍高密度,并且密度一般较均匀,无钙化或坏死,多为不均匀强化 The literature reported CT sweeps evenly generally for slightly the low density, the equilibrium density or slightly the high density, and the density is generally even, does not have the calcification...
http://blog.sina.com.cn/s/blog_450801a90101dptz.html Altium designer 中PCB封装经常能见到IPC low density(低密度)、IPC medium density(中密度)、IPC high density(高密度) 之类的同一种封装,例如TSSOP16,为什么这么表述? IPC是美国“印制电路板协会”(“The Institute of Printed Circuit“)的英文缩写。
The temporal evolution of two model high-density/low-density (HDL/LDL) interfaces was examined from molecular dynamics (MD) calculations at temperatures close to the predicted second critical point of water for three water models. In all cases, interfacial density equalisation occurred rapidly showing...
The two most important types of lipoproteins are high-density lipoproteins (or HDL) and low-density lipoproteins (or LDL). 最重要的两种脂蛋白分别是高密度脂蛋白(HDL)和低密度脂蛋白(LDL)。 article.yeeyan.org 4. Macrophages and Endothelial Cells Oxidize Human Plasma High Density Lipoproteins 巨噬细...
●High energy density: High voltage batteries have high energy density, which means more energy can be stored under the same volume and weight. ● Higher conversion efficiency: The energy conversion efficiency of high-voltage batteries is usually higher than that of low-voltage batteries, making th...
3) Low-rise high density dwelling house 低层高密度住宅 1. Because Low-rise high density dwelling house has the advantages of comfortable size, intimity to natural environment and flexible use of space, it is becoming a popular pattern of construction. 低层高密度住宅在对土地资源的节约基础上...
FIELD: chemistry.;SUBSTANCE: present invention relates to synthesis of medium and high density polyethylenes with a single catalyst composition. A method of polymerising ethylene and α-olefin is described, which involves mixing ethylene at partial pressure at least equal to 1300 kPa and optionally ...
high/low,高/低,外献论文里看到 结果一 题目 形容frequency,density,temperature,energy等物理量大小的词是high/low,small/big or large?或是别的形容词?PS要准确 答案 high/low,高/低,外献论文里看到相关推荐 1形容frequency,density,temperature,energy等物理量大小的词是high/low,small/big or large?或是别...
High-density Polyethylene (HDPE)高密度聚乙烯是一种由乙烯与少量-烯烃单体共聚而成的高结晶非极性合成树脂，是在较低压力下合成，故又称低压聚乙烯。其分子结构主要为线型结构，分子中支链少，结晶度高，密度大，具有较高的使用温度、硬度和机械强度，耐化学性能好。中国石化高密度聚乙烯类别齐全、牌号众多，能够...
Furthermore, the high-resolution image must have high contrast and be quantitative in the same sense as the low-resolution image almost always is. Here, relaxographic MR images (naturally segmented quantitative 1H2O spin-density components) are used. Their essentially complete contrast serves to ...
