For an arbitrarily time-varying system, a series of hankel matrices are established directly from the combined measurements of displacement, velocity and acceleration together with the input excitations, which have been obtained through only one experiment of the system. The varying equivalent state space system matrices of structures at each moment are then identified by singular value decomposition using the forced responses and input forces.

该方法以任意组合的位移、速度、加速度受迫响应信号为测量信息，仅利用一组输入、输出信号组成Hankel矩阵，通过奇异值分解的方法识别出等效状态的系统矩阵，然后运用推导出来的通用时变系统的转换矩阵，将等效状态系统矩阵转换成为实际物理状态下的系统矩阵，从而识别出实际系统的质量、刚度、阻尼矩阵。

In the case of the input signal being spectrally colored, the conventional adaptive feedback cancellation algorithm suffers from bias caused by the correlation between the output signal and the input signal.

This paper is mainly the dynamic input-output model that the time lag is one, which is base on the above models. After studying, we consider stochastic factor step by step in it, namely when consumption coefficient matrix is stochastic (when investment matrix is stochastic, it is almost same. So we dont research it), and they are both stochastic, then we research the stable increase solution. We utilize the means of the modern stochastic analysis and Markov process, that the stochastic dynamic input-output model don not exist the stable solution is proved. Namely, economic system must is adjusted constantly. The probability that the collapse time of the economic system is o is one.

Said that to implement the proactive fiscal policy, governments at all levels must properly carry out their duties to raise funds, by adjusting the expenditure structure, the general expenditure compression, clearing the stock of capital, merging special funds, and concentrate surplus, a new financial and transfer payments by the volume of funds, local bonds issued for a variety of methods to raise funds through multiple channels to increase government input, with the central input to form a concerted effort to strengthen the overall size of government investment.

A parser can decode the next symbol from an encoded input stream by walking down the tree from the root, at each step choosing the edge corresponding to the next input bit.

For example：/\ Symbol Code 0 1 ----------/ \ A 00 /\ B B 1 0 1 C 011 / \ D 010 A / 0 1 / D C 解码器可以解码输入的内容：让输入的流从这个树的根结点走到叶子结点，每次的前进都选择与流中下一位相同的一边。

Secondly, the properties of output sequences of stop-and-go clocked combiners are discussed. It is proved that the output sequences are stationary and obey strong law of large numbers and central limit theorem. Using the probabilistic model properly built, we analyze the rate of coincidence between the output sequences of two kinds of generators with basic operations and corresponding LFSRs sequences. All the computational formulae are derived. A recursive algorithm for efficiently computing the poster probability of partial input strings and corresponding joint probability is introduced. Moreover, divide-and-conquer attacks on this kind of generators which reconstruct the initial states of the input stop-and-go generators individually are proposed.
