最近国家物价局、化工部、中国石化总公司发出通知决定调整纯碱、烧碱、聚氯乙烯等产品价格,具体规定如下: 一.纯碱。国家物资局鉴于天津碱厂生产纯碱需用的原盐和其它原材,燃料大幅度提价,致使纯碱成本上升,执行国家统一定价发生亏损,为缓解企业困难,维持企业正常生产,决定从1988年4月20日起允许天津碱厂的纯碱价格可在国家统一价格每吨390元基础上加价15%,作为临时出厂价格。二.烧碱。国家物价局鉴于原盐等价格上升,短途运费增加等因素,致使生产烧碱 相似文献

A neutron detector array was used in a breakup reaction experiment at RIKEN with an 82.5 MeV/u 8He beam impinging on the CH2 and C targets. The array was calibrated using the cosmic ray, the γ ray from the 6 He+Pb reaction and the mono-energetic neutrons from the 7Li(p, n)7Be(g.s.+0.43 MeV) reaction. The position resolution, timing resolution and neutron detection efficiency were obtained accordingly. Cross-talk rejection conditions were developed based on analysis of the data taken from the 7Li(p, n) 7Be(g.s.+0.43 MeV) test experiment, and finally a preliminary two-neutron correlation function for the 8 He breakup reaction was investigated. 相似文献

An experiment for knockout reaction induced by 8He beam at 82.5 MeV/nucleon on CH2 and C targets was carried out. The 6He and 4He core fragments at forward angles and the recoiled protons at large angles were detected coincidently. From this exclusive measurement the valence nucleon knockout mechanism and the core knockout mechanism are separated, which can be applied to the exclusive spectroscopic study on the structure of exotic nuclei. 相似文献
