The block polymer has sharp phase separation with increasing the content of isoprene. S-I/B-S嵌段聚合物与SBS相似,表现出两相分离的结构,而且随着异戊二烯含量增多,相分离程度增加。
The amphiphilic block copolymers have stronger assembly ability of forming molecular order system, because of the hydrophilic/ hydrophobic nature and micro-phase separation character of their molecular chains. 两亲嵌段共聚物的两亲性及其分子结构的微观相分离性使其具有较强的形成分子有序体的自组织能力。
Analytical solution of the entire response for a portal frame impacted at its midspan by a mass block is attained in terms of the concept of the separation of elasticity and plasticity, in which strain rate effect is taken into account by relating it to instant velocity. 最后应用弹性与塑性分离的思想,以即时速率计入应变率效应,获得了刚架跨中受到质块冲击时响应全过程的解析解。
The algorithm uses the multiple time-delayed de-correlation method and iterative calculation mode to get the separation matrix and no block separation for the samples is needed, so the computing cost is low. 算法利用样本的多时延解相关方法以及迭代计算的形式获得盲混合信号的分离矩阵,无需对观测样本进行分块处理,计算工作量低。

Each node represents one DEM data block. According this separation, by quad-tree data structure can get global different resolution DEM data storage architecture. 每个结点表示一个DEM数据分块,根据如此剖分,由这棵四叉树结构就得到全球范围不同分辨率的DEM数据存储结构。
NMR and TEM results suggest that the block polymer has phase separation. 通过NMR、TEM表征了S-I/B-S为三嵌段聚合物,且具有微观相分离结构。
The design of deviation rectifying and stabilizing on block curved reinforced concrete box girders of Shi-Yi-Jing Rd Grade Separation in Tianjin provides practical experiences for constructions of this kind. 通过对天津十一经路立交桥连续曲线钢筋混凝土箱梁的纠偏加固设计,为此类工程提供了实践经验。
The way of transmitted data changes from pass block to pass block buffer, so that each node only requests data from the buffer. This achieves a separation between father and son nodes. 这种设计主要将父子节点间传送数据的方式由传递块改为传递块缓冲区,这样操作节点只对缓冲区读写数据,父子操作节点之间实现了分离。
We choose the block copolymer PSF-b-PEO with microscopic phase separation structure as the MALDI target coating materials, and then made use of the polymer film for on-plate desalting and enriching of trace peptides. 我们选择微观相分离结构的嵌段共聚物PSF-b-PEO作为MALDI靶涂层,然后利用制作的聚合物涂层进行痕量多肽的靶上除盐和富集工作。
Due to the presence of the star-shaped block copolymer in situ produced, the phase separation of PPO induced by reaction was confined to the nanometer scale. 该反应在原位生成了星形嵌段共聚物,随着固化反应进行,PPO的相分离被限制在了纳米尺度上。
Methods: The culture of tissue block and enzyme digestion was used for the SF separation respectively. Besides, every passage of SF cells was carefully observed under microscope, and the curves of their growth were measured as well. 方法:分别采用组织块法、酶消化法分离培养SF,对不同代次SF细胞进行相差显微镜观察、生长曲线测定。
