The tumor cell lines were HepG2 and HL60. Results The extracts of Livistona chinesis induced significant growth arrested in two malignant tumor cell lines which cultured in vitro.

结果 蒲葵子提取物的各萃取部位在体外对肝癌细胞HepG2和白血病细胞HL60有明显的抑制作用，正丁醇部位的半数抑制率分别为7.94和10.72，效果最为显著。

Each modulated TFSK symbol is divided into two orthogonal sub-symbols, and the new scheme is constructed by differently combining the sub-symbols with the different transmit diversity gain able to be achieved by noncoherent processing at the receivers.

将已调的时频信号分解为互正交的两子信号，同时运用不同的排列组合方案即可得到不同的分集增益。

We choose the effective video as the emotion induce materials, the comedy video was used to induce positive emotion and earthquake tragedy video was used to induce negative emotion. The self-esteem variable includes explicit self-esteem and implicit self-esteem. In my experiments I set four specific situations: succeed, failure, social appraisal and self appraisal, there were also substitutions in achievement condition, such as noncontingent condition.

研究中对情绪状态的引导选取了被证明比较有效的电影视频材料，其中包括喜剧视频剪辑和汶川大地震视频剪辑，用以诱发出正性情绪和负性情绪两种状态；对于自尊变量，本研究从外显自尊和内隐自尊这两个方面来考察；并且在实验一和实验二中主要设置了四种实验情境即成功情境、失败情境、社会评价情境和自我评价情境，而在成就实验情境中又设计了几种重要的子情境。

In a fluid moving nonuniformly, however, the phonons' velocity is altered and their wavelength can become stretched, just like photons in a curved spacetime.

然而，在流动不均匀的流体中，声子的速度会改变，而且它们的波长也会拉长，正如同弯曲空间中的光子一般。

In the nature of physics,it consists with human's cochlea filter properties;in the sense of mathematics,Bark wavelet transform is a kind of non orthonormal but overcomplete,reversible and self inverting wavelet transform.

在感知特性中，它与人耳的听觉系统是直接吻合的：在数学上，它是一种非正交的但却是超完备的，可逆且是自反演的子波变换。

According to the relationship of wavelet transforms and perfect reconstructional FIR filter banks, this paper presents an algorithm for de-noising with Donoho non-linear soft-threshold in defferent levels of multiscale space through rearranging the input data before convolving and filtering and sub-sampling.

本文从子波变换与完全重构FIR滤波器组的特定关系出发，将输入数据按一定规律重新排列之后实时地将数据分解到不同的尺度空间，然后经过正交子波基的Donoho非线性软门限消噪处理。

In 1987, the notion of a splicing system was introduced by Tom Head in [3] as a mathematical model of restriction enzyme digestion and subsequence religation in the recombination of DNA molecules.

摘要1987年，Tom Head发表了一篇论文，引入拼接系统的概念作为限制酶与DNA作用、进行DNA重组的数学模型。更重要的是，他还证明正则语言中的一类——严格局部可测语言，与拼接语言的子类——持续拼接语言等价。

At first, this paper describes that the Ricker wavelet is regarded and applied for the seismic forward modeling, data processing and backward interpretation.

本文首先阐述了Ricker子波在地震的正演模拟、资料处理和反演解释中得到的广泛重视和应用。
