As beams transmit mostly in the core of waveguide , also the changes of thickness and refractive index of the sample will quickly and sensitively affect the propagation constant , the information of sample can be obtained through monitoring the propagation constant . 4 . the periodic anti - resonant reflecting layers are presented 由于光束集中在作为波导层的待测物之中传输,而由待测物质的厚度、折射率等参数带来的微小变化均会引起导模传播常数的变化,通过监测传播常数的变化即可得到待测物质的信息。
( 2 ) under certain temperature , for a short external cavity , a slight change of the external cavity length will result in an obvious variation of the lasing wavelength ; and for a long external cavity ( > 10cm ) , the change of the external cavity length gives almost no effect on the lasing wavelength 当温度保持一定时，对于短外腔，外腔长度的微小变化可以导致fgesl的激射波长产生显著的变化;而对于长外腔(尤其当外腔长度大于10cm )时，外腔长度的变化对fgesl的激射波长基本没有影响。
The water turbine regulation system is a complicate auto - controlling system , it ' s small fluctuation dynamic course means : when the water turbine regulation system is interfered by tiny disturbance of load or command signal , the change of different parameters in the system is less , we can thought they are subtle change near by the discussing conditions , so we can make each tache in the system linearization , that is , describe the dynamic specialty of each tache and the whole system by means of linear differential equation 水轮机调节系统是一个复杂的自动控制系统，其小波动过渡过程是指水轮机调节系统在受到微小的干扰(负荷或指令信号扰动)时，系统中各参数的变化都较小，可以认为是在所讨论工况点附近作微小变化，则可将调节系统各环节加以线性化，用线性微分方程式来描述各环节及整个系统的动态特性。
And the process of creating learning enterprises should follow : " starting from the tiny change " , " focusing on developing factors and paying more attention to restrictive factors " and " driving the learning circulation " . finally , the practicing ways of creating learning enterprises may be appraised by the criterions of individual achievements , strengthening the relationships among the people who want to create the learning enterprises and improving the organization ' s performance 这个过程应该遵循从微小变化开始、利用成长因素更要关注限制因素以及推动深层学习循环的基本思路进行，并且可以从个人成果、实践者联系的增强以及经营成果的改善三个方面来评价创建行为。
It is shown that the nonlinear characteristics change frequently with the slight variations of parameters , and the border collision results in remarkable oscillations of queue length and the parameter sensitivity to increase the end - to - end delay and reduce the link utilities , thus it is necessary to avoid sub - critical bifurcation as designing system parameters 研究结果表明，系统参数的微小变化会导致系统动力学特性的频繁改变；边界碰撞分岔导致队列长度的大幅度振荡，在增大端到端的时延抖动、降低链路利用率的同时，使得系统对参数表现出极端敏感性；在配置系统参数时，应尽量避免亚临界分岔的发生。
Based on the testing principle of wheatstone bridge , a simple testing system is set up with two cascaded amplifiers and two cascaded butterworth lowpass filters . the varying voltage is tested by the system as the pressure is changed . experiment data are obtained , which also prove the feasibility of the design and the process flow 5 .基于惠斯顿电桥的测量原理,利用两级放大电路和两级巴特沃思低通滤波电路搭建了一简单的测试电路系统,成功地检测出了输出电压的微小变化值并得出了一些初步的实验数据,验证了芯片设计和工艺流程的正确可行性。
