查询词典 latency period

The thermal gradients of the depression decreased during the Cenozoic time. However, it decreased quickly in Eogene, but only changed a little during the Neogene period The thermal gradient was 540～500℃/km during the period of the Kongdian group deposition, 500～400℃/km during the period of Shahejie group, 400～385℃/km of Dongying group and 385～355℃/km during the Neogene.

研究结果表明，济阳坳陷新生代以来的古地温梯度是逐渐降低的，但在早第三纪时期下降的幅度较大，而在晚第三纪－第四纪则下降的幅度明显较小；济阳坳陷在孔店组沉积时期的地温梯度为540～500℃/km之间，沙河街沉积时期为500～400℃/km，东营组沉积时期为400～385℃/km，晚第三纪时期为385～355℃/km，第四纪以来基本未变。

Based on the return map and the principle of closed vectors, a new method is proposed to extract unstable periodic orbits embedded in chaotic attractors. As examples, the UPOs embedded in chaotic attractors of Logistic, Hénon and Lorenz are extracted respectively by this method. And our results of Skewed Hénon map also be compared with Nusse's. These results suggest that this method is valid for unstable periodic orbits from period one to period infinite of arbitrary dimension chaotic system. The dynamic considerations of spiking and UPO coding for individual neuron and neural system under external periodic and chaotic exciting stimulus also be studied in this dissertation. A lot of spiking phenomena, such as synchronization, period, and chaos appear alternatively with the changing of the stimulus frequency. For the small stimulus frequency the neuron could completely convey the periodic signal in synchronous anti-phase into interspike intervals sequences. For the slow time–scale chaotic input, the output two ISI sequences are reciprocally related to input signals, and their oscillation wave shape in time course can be derived from that of the input signals variation, furthermore, the similar input sequence and order of UPOs, distribution of LES and value of KYD remain in attractors reconstructed from ISI sequences.

发现周期信号在单个神经元传递过程中，随着激励频率的改变，神经元输出的峰峰间期interspike interval时间序列呈现出周期、混沌和准周期的交错变化，特别当外加激励信号频率较低时，周期信号可以通过神经元ISI序列以反相同步的周期运动形式传递下去；同时无论是周期还是混沌激励信号，在神经系统中的传递均与其自身强度和神经元之间的耦合强度的大小密切相关；快变时间尺度的混沌激励信号在耦合的神经系统传递过程中，会造成大量基本信息的丢失；而慢变时间尺度的混沌激励信号在神经系统传递中，它的非线性特征信息，如混沌吸引子、不稳定周期轨道、Lyapunov指数谱和分形维数，会通过系统输出的ISI序列部分地重现出来，如与输入慢变时间尺度的混沌激励信号相比，神经系统输出的ISI序列具有：相似几何形状的混沌吸引子、相近的Lyapunov指数谱和分形维数、局部结构相同的不稳定周期轨道的排列方式。

The main conclusions of this chapter are the following: There is no absolute regional convergence since 1978, even the period were divided into two stage: 1978-1991 and 1992-2002; There exists absolute convergence among the provinces in eastern region in the period 1978-1991, the phenomena is alike to the central and western regions, so the club convergence is the fact of the regional economic growth in this stage; From 1992 to 2002, instead of the club convergence, there exists conditional convergence, human capital, capital investment, international trade and FDI influenced the regional economic growth rate markedly; The distribution of income across provinces don't transform from a unimodal into a bimodal distribution.

本章的基本结论是：改革开放以来不存在绝对收敛，即使将整个改革时期划分为1978—1991年和1992—2002年两个区间也是如此；1978—1991年期间，东部地区和中西部地区内部各自存在人均GDP和劳均GDP增长的收敛，从而形成了俱乐部收敛；1992年之后，并不存在俱乐部收敛，但存在一定的条件收敛，人力资本、物质资本投资、国际贸易和FDI对劳均GDP增长有着重要的正向影响；收入分布并没有发生由单峰向双峰分布的转变，总体上单峰的态势依然十分明显。
