古代深海硅质岩-粘土岩-碳酸盐岩系列(SAC)是沉积在远洋或深海的硅质岩、粘土岩和碳酸盐岩及其过渡岩石类型的统称.在借鉴现有相关分类的基础上,提出了基于三端元矿物组成的SAC岩石系列的三角图分类新方案.以碳酸盐矿物-粘土矿物-石英作为三端元组分,按照“纯”(>90%)、“主”(50%~90%)、“质”(50%~25%)、“含”(<25%)的定量分类标准,并利用等边三角形中线,将SAC岩石系列划分为...
2017年12月6日,由中国标准化研究院、浙江省质量技术监督局主办,中国标准科技集团、杭州市质量技术监督局承办的“ANSI-SAC团体标准合作与发展工作会”在浙江杭州成功举行。中国国家标准化管理委员会副主任殷明汉、美国国家标准化机构(ANSI)国际政策副总裁Joseph Tretler、浙江省质量技术监督局副局长赵孟进、中国电子学会总部党委书记张宏图等出席会议。
In an Oceanography article published 13 years ago, three of us identified salinity measurement from satellites as the next ocean remote-sensing challenge. We argued that this represented the next "zer...
The symmetry-adapted-cluster configuration interaction (SAC-CI) method is used for ab initio calculation of electronic structure of HCl+ and HBr+ molecular ions. Potential energy curves (PEC) are obta...
Ambient particulate matter (PM) samples were collected on quartz filters at a rural site in central Ontario during an intensive study in 2007. The concentrations of organic carbon (OC), pyrolysis orga...
In this study the global lapse-rate tropopause (LRT) pressure, temperature, potential temperature, and sharpness are discussed based on Global Positioning System (GPS) radio occultations (RO) from the...

Nonlinear permutations of GF(2^n) with strong cryptographic properties have important applications in cryptology such as DES-like block ciphers, hush functions and stream ciphers. In paPer [1], we pro...
采用SAC (starch-assisted combustion)法和高温固相法分别合成锂离子电池正极材料LiNi0.01Co0.01Mn1.98O4, 使用X射线衍射仪、BET法、粒度分析仪及扫描电子显微镜对合成材料的结构及物理性能进行了表征. 将合成材料作为锂离子电池正极活性材料, 用循环伏安、交流阻抗及充放电测试的电化学测试方法对材料进行了电化学的研究. 结果表明, 两种方法制备的材料均为...
The growth rate during yolk absorption, yolk conversion efficiency, dry weight and water contents of brook trout (Salvelinus fontinalis Mitchill, 1814) larvae were observed and the relationships betwe...
Bovine yolk sac at day 24 of pregnancy, and placental membranes (chorion and allantois) from days 70 and 100 of pregnancy were isolated and cultured in a modified minimum essential medium in the prese...
The silkworm moth escapes from the pupal-protection case by utilizing cocoon-digesting enzymes. The rectal sac was examined in relation to the behaviour of the animal. Pupae and pharate adults were ob...
The effects of 12 combinations of pH (4.5 and 7.0), aluminium (4 and 8 ?mol/L) and calcium (10 and 100 mmol/L) on survival and body mineral (Ca, Mg, K and Na) concentrations of rainbow trout ( Oncorhy...
