BINELOCA 程序与广东岭澳核电站大破口失水事故分析

ＢＩＮＥＬＯＣＡ程序是在吸收国外先进大破口失水事故分析计算机程序的基础上，针对我国现有大破口失水事故分析程序的不足和工程应用方面的问题，采用了一些成熟的、新型的和当今国际公认的瞬态热工水力数学物理模型以及水和蒸汽性质参数计算公式改编而成的大破口失水事故分析程序。通过对广东岭澳核电站大破口失水事故的计算表明，ＢＩＮＥＬＯＣＡ程序计算的结果与法国计算的结果是一致的。     

Coaxial Alginate Hydrogels: From Self-Assembled 3D Cellular Constructs to Long-Term Storage

Alginate as a versatile naturally occurring biomaterial has found widespread use in the biomedical field due to its unique features such as biocompatibility and biodegradability. The ability of its semipermeable hydrogels to provide a favourable microenvironment for clinically relevant cells made alginate encapsulation a leading technology for immunoisolation, 3D culture, cryopreservation as well as cell and drug delivery. The aim of this work is the evaluation of structural properties and swelling behaviour of the core-shell capsules for the encapsulation of multipotent stromal cells (MSCs), their 3D culture and cryopreservation using slow freezing. The cells were encapsulated in core-shell capsules using coaxial electrospraying, cultured for 35 days and cryopreserved. Cell viability, metabolic activity and cell–cell interactions were analysed. Cryopreservation of MSCs-laden core-shell capsules was performed according to parameters pre-selected on cell-free capsules. The results suggest that core-shell capsules produced from the low viscosity high-G alginate are superior to high-M ones in terms of stability during in vitro culture, as well as to solid beads in terms of promoting formation of viable self-assembled cellular structures and maintenance of MSCs functionality on a long-term basis. The application of 0.3 M sucrose demonstrated a beneficial effect on the integrity of capsules and viability of formed 3D cell assemblies, as compared to 10% dimethyl sulfoxide (DMSO) alone. The proposed workflow from the preparation of core-shell capsules with self-assembled cellular structures to the cryopreservation appears to be a promising strategy for their off-the-shelf availability.

一种Ling选择进位加法器

设计一种Ling选择进位加法器,组间采用Ling进位代替传统的进位,利用内部连线与节点扇出平衡的并行前缀逻辑产生进位机制,并对通常的进位选择模块进行调整,以使其适合Ling进位。该加法器兼具了Ling加法器的快速性,又避免了逻辑产生的复杂性。实验结果表明,与超前进位加法器相比,该加法器的速度提高12％左右。

“长铗归来乎”新解

各书对"长铗归来乎"之训释不一,通过对"铗""来"二字的详细研究,得出"铗"为"剑"义、"来"为"回来"义,最后作出新解:长剑啊,回来(剑鞘)吧!"长铗归来乎"实为冯谖运用比喻的修辞手法,以长铗自喻:剑已出鞘,正如自己已因愿为其谋而寄食门下;冯谖要剑马上回剑鞘,其实是说要自己快回到属于自己的地方,离开现在所处的地方。
