SDAS-Ⅱ型数据采集与分析系统

The SDAS and average length of eutectic silicon have different sensitivity to the cooling rate .

研究发现，合金的平均二次枝晶臂间距和共晶硅平均长度对冷却速度的敏感性不同。

SDAS directly transmits the data of all the network nodes to the sink node .

SDAS算法直接将所有网络节点的数据传输给网关节点。

When there is no rare earth adding to the alloy , the SDAS have the highest sensitivity to the cooling rate .

未添加稀土元素的再生铝合金ADC12的二次枝晶臂间距对冷却速度的敏感性最高。

This thesis proves that this problem is NP-complete , and proposes two approximation algorithms called SDAS and CDAS respectively .

本文证明该问题是NP完全问题，并提出了两种近似算法SDAS和CDAS。

However , when the rare earth addition amount is 0.1 % , the SDAS have the highest sensitivity to the cooling rate compared to other addition amount .

添加了稀土元素变质后，其添加量为0.1%的情况下，合金的二次枝晶臂间距对冷却速度的敏感性最高。

The grain size and SDAS increase with the decrease of the distance from the cross section to the ingate , reduce with the increasing of section thickness .

对于同一截面而言，晶粒度和二次枝晶间距均随截面壁厚的增加而减小，对于不同截面，晶粒度和二次枝晶间距随着所在截面与浇冒口的距离减小而增大。

Methods : SPSS 11.0 and SDAS software packages were used to retrospectively analyze the damages to the heart , kidney and peripheral blood in 330 clinically confirmed SARS cases .

方法：回顾性总结330例临床确诊的SARS患者心脏、肾脏损害及外周血象变化特点，采用SPSS11.0及SDAS软件进行统计分析。

In addition , the data aggregation latency of CDAS algorithm is lower than that of SDAS algorithm except the scenarios where the transmission radius of a node is large .

另外，除了节点传输半径比较大的场景，CDAS算法的数据聚合延迟都要低于SDAS算法。

The structure of columnar crystals is observed for billets cast without M-EMS , and equiaxed structure for billets cast with M-EMS , in which SDAS decreases obviously with increase of stirring current .

无M-EMS的铸坯接近中心的区域，仍然是枝晶臂发达的柱状晶组织；采用结晶器电磁搅拌，促使铸坯中心区域形成粒状等轴晶组织；

Eg ( band gap ) of compound 2 ~ 5 decrease with increase of chain length ( n ) of SDAS , their Eg are controlled by valence band of Ag-4d / I-5p .

化合物2~5的Eg（带隙）随着导向剂链长（n）的增大而递减，其Eg受Ag-4d/I-5p为主要成分的价带所控制；
