| 1. | The results show that binding energies per nucleon at each density and various asymmetry parameters fulfill the empirical parabolic law and the asymmetry energy is density dependent . it is found that both scalar and vector potentials of neutron in the neutron rich nuclear matter become stronger although the isospin dependence is not stronger . we compare our results with those in a simple method , where the dbhf nucleon self - energies are extracted from the momentum dependence of the single - particle energy
首先我们要求在每一个密度及各种不对称系数的核物质中，相对论平均场（ rmf ）计算出的核子标量与矢量自能与dbhf计算出的标量与矢量自能一致，从而得到在rmf下的密度依赖的有效介子核子耦合常数，包括同位旋标量介子。 | | 2. | A reliability experiment of thermal aging was carried out for the two types of joints , scanning electron microscopy , energy dispersive x - ray spectrometer and micro x - ray diffractomer were adopted to investigate the interfacial evolution behavior of joints , and kinetics model of imc formation was established . the results show that imc growth follows the parabolic law as a function of aging time at certain aging temperature , imc growth is more sensitive to the aging temperature than the aging time , the activation energy of cu - al imc growth is 97 . 1kj / mol and the major forming cu - al imc are cual2 and cu9al4 , the activation energy of au - al imc growth is 40 . 1kj / mol and the main au - al imc are au4al and au5al2 , with au2al and aual at the interfacial periphery of joints , the rate of cu - al imc growth is about 1000 times slower than that of au - al imc , and kirkendall voids and cracks are easily appeared during thermal aging in gold ball bonds while voids and cracks are absent in copper ball bonds even after aging at 200 for 2900 hours and 250 for 169 hours
研究结果表明:金属间化合物厚度与老化时间的关系符合抛物线法则,金属间化合物的生长对老化温度比老化时间更加敏感; cu - al金属间化合物生长的激活能为97 . 1kj / mol ,老化后金属间化合物呈层状分布,主要相为cual2和cu9al4 ; au - al金属间化合物生长的激活能为40 . 1kj / mol ,主要相为au4al和au5al2 ,同时在界面周边区域生成了au2al和aual ;老化过程中cu - al金属间化合物生长速率比au - al金属间化合物生长速率小103数量级;金丝球键合点200老化96小时出现了明显的kirkendall空洞和裂纹,但铜丝球键合点200老化2900小时和250老化169小时都没有形成空洞和裂纹。 |
