Compared to that of two-arm PCL18–DBAS (Figure 1a), the NMR spectrum of the mixture revealed that characteristic methylene proton signals of DBAS, which initially overlapped with signals corresponding to the PCL main chains, shifted downfield to d=4.5–4.7 ppm upon complexation (Figure 1c).

相比于二臂PCL18-DBAS（图1a），此混合物的核磁共振谱揭示，DBAS的特性亚甲基质子信号，他们一开始是与相应于PCL主链的信号重叠的，而在络合作用下则向下面漂移到δ＝4.5～4.7ppm（图1c）。

Finally,about the boards"design in the engineering process,some skills of the traces and placement of the signals between controller and the DIMM(Dual In-line Memory Module) socket are analysised in particular. In addition,DDR chip"s power consumption and the signals timing margin have been discussed.

本文最后还对DDR存储器应用所涉及到的工程化问题进行研究，深入分析了PCB设计中DDR SDRAM的电气特性及存储控制器和DIMM(Dual In-line MemoryModule，双列直插式存储器模块)条的布局布线问题，另外也进行了相关功耗的计算和信号时序容限的计算。

The proposed method is verified by computer-simulating with biological signals such as clinical electroencephalograph signal and other kind of signals.

By re-constructing the system, the residual error dynamic characteristics of unknown input and fault signals including unknown disturbances and modelling error are obtained. The energy norm indexes of disturbance and fault signals of residual error are selected separately to reflect the restraint of disturbance and the sensitivity of faults, and the design of fault detection observer is described as an optimization problem.

通过对系统进行重构，获取了包括未知扰动、建模误差等未知输入信号和故障信号的残差动态特性，分别选取残差的扰动信号和故障信号的能量范数指标来体现其对扰动的抑制作用和对故障的灵敏性，并将故障检测观测器的设计描述为一个优化问题。

The most common approach is to consider the problem of machine equivalence which defines two synchronous design specifications functionally equivalent if, clock by clock, they produce exactly the same sequence of output signals for any valid sequence of input signals.

最常用的方法是考虑的问题，机等价定义两个同步设计规格等同功能，如时钟的时钟，它们产生完全相同的序列输出信号的任何有效的序列输入信号。

It is the key factor regulating programmed cell death in pathogen,evocator and hormone responses.H_2O_2 has also been proved to play the signal role in defensive response to environmental stresses.H_2O_2 is known of directly regulating the expressions of numerous genes and some of these genes relate to plant defense and hypersensitive response.H_2O_2 also interacts with other signal systems,especially hormone signal system,and forms upstream or downstream components of hormone-mediated signal-transmitting passageways;more importantly,H_2O_2 also work to exert influence on or modify other secondary signals such as calcium signal between which and H_2O_2 many interactions take place;and both of these two signals regulate interactive tolerances of plants.

已知H2O2直接调节无数基因的表达，其中有些基因与植物防御和超敏反应有关。H2O2还与其它信号系统特别是激素信号相互作用，是激素介导的信号传导通路上的上游或下游组分；更重要的是H2O2还影响和修饰其它第二信使如钙信号的作用，在H2O2信号和钙信号之间发生众多的交互作用且这两种信号分子都调节植物对多种胁迫的交互耐性。

When the residual modes are high frequency modes, it will be suitable to use a filter to prevent the spillover by filtering the measuring signals. The closed loop poles would excurse if the measuring signals were filtered directly.

对于剩余模态和控制模态分离得较好的受控对象，可采用对测量信号进行滤波去除信号中剩余模态分量的方法防止溢出问题。

On the plain scan of CT, the appearances of the aneurysmal bone cyst were the various expansile changes. In destruction of bone, the capsular districts and septation can be seen. On MR T1WI and T2WI, we can see the low signal ring of the diseased region borderline, the diseased region bulk was full of fluid which has miscellaneous signals, it can be seen the low or slightly high signal. In the diseased region, the septation which have low signals both on the T1WI and T2WI can be seen.

在CT上动脉瘤样骨囊肿表现为溶骨性骨质破坏，常有不同程度膨胀性改变，骨质破坏区内可见囊状低密度区及骨性分隔，MRI表现为T1WI及T2WI上可见病灶边缘有低信号环，病灶内主体部分充满囊状液体，信号混杂，在T1WI低或中高信号，在T2WI上呈不均匀高信号，病灶内可见T1WI及T2WI上均呈低信号的分隔。

HF communication generally depends on the reflection of signals from the higher F layer and such signals must travel through the D layer at least twice.

HF 通信一般取决于信号的反射从更高的F 层数并且这样信号必须游遍D 层数至少两次。
