查询词典 time delay unit

Chapter 3 emphasizes on the case that the considered systems contain not only impulse but also time delay. We mainly investigate impulsive parabolic systems with time delay and neutral impulsive parabolic systems. Section 3.1 discusses the oscillation of impulsive parabolic systems with time delay under Robin boundary condition and obtains some useful criteria via first order impulsive differential inequalities with time delay. Section 3.2 studies the oscillation of neutral impulsive parabolic systems under Neumann boundary condition and Robin boundary condition, respectively, and obtains some sufficient conditions for oscillation and strong oscillation via first order neutral impulsive differential inequalities.

第三章针对于"脉冲"与"时滞"共存的复杂情形，仍采用反证法讨论了含时滞的脉冲偏微分系统的振动理论，具体研究了脉冲时滞抛物系统和中立型脉冲时滞抛物系统。3.1节考虑了脉冲时滞抛物系统的振动理论，借助于一阶脉冲时滞微分不等式的解的性质，得到了满足Robin边界条件的脉冲时滞抛物系统的若干振动准则；3.2节考虑了中立型脉冲时滞抛物系统的振动理论，借助于一阶中立型脉冲时滞微分不等式的解的性质，分别给出了满足Neumann边界条件和Robin边界条件的中立型脉冲时滞抛物系统的若干振动和强振动准则。

The results were as follows:The unit-roots characters (weight, length etc.) and 15N absorption decreased progressively downward. 15N absorbed by any unit roots could be transported from root to tiller and from tiller to tiller, but the transporting ratio was different.The pattern was as follows: when 15N was offered to total roots of plant or only to primary roots, it was transported to main stem and then decreassingly to tillers from lower unit to upper one, when 15N was offered to n unit-root, it was transported to n unit tillers, then to n + 2 or n-2 unit tillers , followed by n + 1 or n -1 unit tillers , and finally to other unfeed roots.

各单位根吸收(15)~N后，蘖根之间，蘖蘖之间皆可互相运转，但其运转比例不同，其功能模式是：(15)~N喂全株根或专喂初生根，则先供给主茎，其次是分蘖，而且随蘖位升高而递减；喂n单位根，则先供给n单位本身，其次是n+2或n-2单位的蘖，然后是n+1或n-1单位的蘖，最后是未喂(15)~N的根系。

A system for transmitting a signal via diversity antennas (60, 70; 150, 160, 170, 180; 190, 200) includes: at least one delay element (100) for generating at least one delayed replica of the signal subject to a given delay; the signal and the at least one delayed replica being adapted to be transmitted via the diversity antennas (60, 70; 150, 160, 170, 180; 190, 200), and a control unit (110) for the at least one delay element (100) for varying (110) the given delay (100), whereby the signal and the at least one delayed replica, transmitted via the diversity antennas (60, 70; 150, 160, 170, 180; 190, 200), give rise to alternate constructive and destructive combinations therebetween.

一种用于经由分集天线(60、70；150、160、170、180；190、200)传送信号的系统包括：用于生成受到给定延迟的信号的至少一个延迟复件的至少一个延迟部件(100)；该信号和该至少一个延迟复件适合于经由该分集天线(60、70；150、160、170、180；190、200)传送，以及用于至少一个延迟部件(100)改变(110)该给定延迟(100)的控制单元，由此该信号和该至少一个延迟复件经由分集天线(60、70；150、160、170、180；190、200)传送，导致在其间交替的建设性和破坏性组合。

The results show that the system can keep certain smoothness with short delay, but the control precision can decline with the accretion of time delay, long random delay will not only reduce system expeditiousness, but also the smoothness and control precision at the same time. If the random delay is long enough, it can destroy the stability of networked control systems.

研究结果表明：系统在较小的延时下仍能保持一定的稳定，随着延时的增大，系统的控制精度有所降低；而较大的随机延时不但降低系统的总体快速性，同时，使系统的稳定性和控制精度明显降低，而当随机延时大到一定程度时，系统的稳定性难以保证。
