For the requirement of more negative differential resistance ( ndr ) routes , three split quantized energies are formed in the four - period inp / ingaas superlattice structure with relatively thin ingaas quantum wells under ideal flat - band condition , and high - field domain in the superlattice is formed under sufficiently large operation bias 为获得?多轨迹的负微分电阻，本研究组件使用?相当薄之砷化铟镓?子井，可使四周期磷化铟/砷化铟镓超晶格结构在平带情况下形成三个分?的?子化能阶，且于足够大的操作偏压下在该超晶格结构中形成?高场区域。
In 1904 , frank alvah parsons joined chase ; six years later , he became the school s president . anticipating a new wave of the industrial revolution , parsons predicted that art and design would soon be inexorably linked to the engines of industry . in 1970 , the school became a division of the new school for social research now the new school 直到一九四年，在法兰克亚曼柏森斯先生的重新领导下，学院开创出室内建筑interior design装潢设计decoration design服装设计fashion design及广告艺术advertising art等新科系，且于一九四年命名为柏森思设计学院parsons school of design 。
As the result of subsequent expansion and reorganization , the university is now comprised of four faculties : the faculty of business administration , the faculty of economics , the faculty of law , and the faculty of international relations . graduate schools offering master s degrees in economics , business administration and law were established in 1974 followed by doctoral programs in 1976 几经拓展及改组之后，现今大学拥有四个院系经营学部经济学部法律学部以及国际关系学部在1974年各院系开设研究所硕士班且于1976年?设博士班当时亚细亚短期大学仍旧继续著之前日本经济短期大学时期的贸易经营课程。
However , the period of service is limited to a maximum of four years ; furthermore , during the first stage and second stage , individuals perfor min g r d service receive the same pay , insurance and welfare as individuals perfor min g regular military service holding nco or officer rank . the new system is thus more equitable 研发替代役，服役期间可以就个人研发专长及未来工作能力持续培育，但其服务时间为4年以内，且于第1阶段及第2阶段之薪俸保险抚恤均比照义务役官士兵办理，其兵役公平性爰已衡平。
