With the development of nuclear energy, how todispose of the nuclear wastes especially high level liq uid wastes (HLLW) is the world′s subject. One strat egy for reducing the main long term hazard of radioac tive waste is to separate actinides from high level liq uid waste (HLLW) and transmute them into short lived or stable nuclides by nuclear reactions in nuclearreactors or accelerator driven transmutation systems.For this subject, many countries have brought forwardmany p… 相似文献

船用柴油机启动阀被拆装或损坏时,冷却水会通过冷却水孔进入燃烧室,对柴油机的性能造成极大的影响。以某机型船用大缸径柴油机为原型,结合仿真分析方法对3种冷却方案的气缸盖温度进行了计算。结果表明:采用在保持冷却水孔布置的基础上,增加启动阀衬套的冷却方案可以有效解决冷却水泄漏的问题,且优化前后的主应力分布情况基本一致,提高了气缸盖的可靠性。 相似文献

A new stripping agent N, N-dimetbyl-3-oxa-glutaramic Acid (DOGA) was used in TRPO process to simplify the TRPO process. The structures of the complexes of the DOGA with Eu(Ⅲ), Nd(Ⅲ), La(Ⅲ) were characterized with extended X-ray absorption fine structure spectroscopy (EXAFS), infrared spectra (IR) and mass spectra (MS). The molecular formula of the complexes of Eu( Ⅲ ) and Nd( Ⅲ ) is deduced to be M(DOGA)3, and only La( Ⅲ ) can form the complex HM(DOGA)4 under condition of high consistency of the DOGA. The coordination number of Ln( Ⅲ ) in the complexes is 8, and all of coordinated donor atoms are O atoms. For Eu( Ⅲ ), Nd( Ⅲ ), the coordination numbers of O atom in the first coordination shell is 6 and the average coordination bond lengths of Ln - O are 0.240 nm, 0.244 nm respectively,while the numbers of the second O shell are 2.4, and the average coordination bond lengths of Ln - O are 0.260 nm,0. 262 nm. For La( Ⅲ ), the coordination numbers of O atom in the first coordination shell is 6 and the average coordination bond lengths of La - O are 0.258nm, while the number of O atom in the second coordination shell is 4.4, and the average coordination bond length of La - O is 0.28 nm. The results of IR and MS show that there is no water coordinating with Ln( Ⅲ ) in the complexes. 相似文献
