查询词典 Doppler shift

So this paper selects national debts as our studying objects. By using principal component analysis method to study the zero coupon yield curve, we find that the movement of the curve yield can be simulated by two factors mostly, that is parallel shift and rotation. Then we quantitative them and get "synthetic parallel shift" and "synthetic rotation".

因而，本文选择了国债作为研究对象，对国债的即期收益率曲线进行主成分分析的结果表明，收益率曲线变动的总体方差绝大部分来自于两个因子的贡献，即水平因子和倾斜因子，本文对这两个因子进行量化处理，得到"综合的平移"和"综合的倾斜"，并在此基础上建立了两综合因子法对债券组合的VaR估值模型。

When realizing on hardware, for an M×N UFPA, at any sampling time, a shift-register is used to store M data which is before the current sample data and the shift-register′s output is updated with the data which is at the same column while the upper row. Meanwhile, a common register is used to store the data which is at the same row while the previous column.

在硬件实现阶段，对于M×N的UFPA器件，在任意采样时刻，利用移位寄存器保存当前采样点之前的M个响应值，使其输出可实时更新为与采样点同列的上一个数据；同时，利用一般的寄存器实时保存与采样点同行的前一个数据，采用同帧行列间内插法实现无效像元的实时补偿。

Results The clinical manifestation of brain stem hemorrhage secondary to cerebral infarction included sudden onset,evelution abruptly,coma,quadriplegia,higher fever and respiratory failure. CT usually do not identify the high dense location of brain stem. Large infarction of cerebral hemisphere may lead to shift the brain laterally and downward to produce herniation with subsequent brain stem compression,shift and distortion. Secondary brain stem hemorrhage occured usually in midderline area of midbrain or pontine.

结果 脑梗塞继发脑干出血的临床特点是发病急、进展快、昏迷、四肢瘫、过高热及呼吸衰竭，CT一般不能发现脑干高密度病灶，病理结果均为半球大病灶脑梗塞，严重海马回疝致脑干严重受压、变形和移位，继发脑干出血以中脑为主，可累及桥脑，主要位于中线部位。

结果发现，交流斯塔克位移的存在使得非简并拉曼过程中原子反转的崩溃与再生现象呈现较好的周期性，并且拉比振荡的频率和振幅均受交流斯塔克位移的影响。

Convention V-belt Continuously Variable Transmission, shifts gears the travel mechanism property fixed constraint, unable full into full play initiative control advantage, to engine and Transmission on the go to hold optimum match, Also takes into consideration acceleration and fuel consumption performance, so this paper research Motorcycles with an Electronically-Controlled Continuously Variable Transmission shift gears planning, to use motor power screw, we shall revolve motion changes rectilinear motion, to push driving sheaves achieved to change speed ratio; Comparison between analysis convention CVT speed ratio shift gears curves of acceleration and fuel consumption performance optimum curves, use engine can hold high performance output or low fuel consumption region run.

中文摘要传统皮带式无段变速器(Continuously Variable Transmission， CVT)，换档行程由於机械特性的限制，无法完全发挥主动控制的优点，让引擎与变速器随时保持在最佳的匹配状态，同时顾及加速性能与燃油消耗，所以本文主要研究机车用电子控制式无段变速系统(Electronically Controlled Continuously Variable Transmission， ECVT)最佳换档规划，利用马达与动力螺杆，将旋转运动改变为直线运动，以推动主动滑轮达到改变减速比；分析传统CVT减速比换档曲线与最佳化曲线之加速性能及燃油消耗比较，使引擎能够保持较高性能输出或较低油耗区间运转。
