上周四，当指针悄悄指向晚间十一时十五分，五百名科学家、工程师汇集到控制室，而附近的普林斯顿等离子物理实验室观众席的人们将目光注视在一排电脑显示屏上。 - Mixers are the key components of many microwave and millimeter - wave systems . the super - heterodyne receiver is always applied in modern communication system , mixer becomes the key component as is at the first part of system . but it is more and more difficult to get the choiceness lo source of the same band with the system is working at high frequency especially in the millimeter - wave . sub - harmonic mixer is a good solution to this problem now . in this circuit we need just half 、 quarter 、 even 1 / 8 of the rf signal frequency . in this paper the design and fabricate of sub - harmonic hmic mixers ( 2 , 4 ) at w - band are introduced
混频器是微波通信、射电天文学、雷达、等离子物理、遥控、遥感、电子对抗,以及许多微波测量系统中至关重要的部件。在现代通信系统中,毫米波频段通常采用超外差接收机,混频器作为第一级就成为关键部件。由于在毫米波频段,同频段高性能的本振源成本高,技术难度大,采用分谐波混频技术是解决此问题的有效途径,只需射频频率1 / 2 、 1 / 4甚至1 / 8的本振频率即可实现混频。 - In 1860 , schrodinger first put forward the concept " schrodinger equations " in quantum mechanics and since then , the study on schrodinger equations has never stopped , for the mathematical description of many physical phenomena belongs to the field of schrodinger equations , such as nonlinear optic , plasma physics , fluid mechanics etc . as for the form of schrodinger equations , linear schrodinger equations was gradually replaced by nonlinear schrodinger equations ; as for the methods of solving schrodinger equations , the modulus estimate of energy , the principle of contraction mapping , fourier transformation and harmonic analysis are used ; as for the space of the solutions , many people have worked on the problem in bounded domain , euclidean space of dimension n , periodic bounded conditions and mixed regions and they also combined it with the generalization from low dimension to high dimension
