As a result of photopolymerization-peripherin-insensitiveto on the ultrared, the place of the laser ablation out sensitive emulsion layers are not affected by infrared laser.

由于平撮合型感平层差红边线不敏锐，因此被激平烧不赚掉边际的感平乳剂层不施红边激平感化。

Animal's welfare can be feed back from their vocalism. We had some experiments to get 35 days old chicken's vocalization in different environment, including normal environment、 light off environment and people's disturbing environment. On the base of Mel Frequency Cepstral Coefficient, We introduction a new algorithm for feature extraction---Subband Mel Spectrum Centroid. We used support vector machine classification model to evaluate the performance of using different sound parameters.

本文通过研究35日龄海兰褐蛋鸡在正常状态、光照与人为干扰等应激下发声信息的变化特征，提出基于子带梅尔频谱质心的优化特征参数，并通过建立支持向量机模型，比较了采用优化特征参数与梅尔频标倒谱系数及其一阶、二阶导数组成的特征参数（MFCC_39）在识别不同应激中的应用效果。

In accordance with such external technology requirements and based on such presumable precondition that we've found a kind of atomic reciprocal PNT combination A which can be used as PNT activation source accelerating along certain orientation once activated by the so-called PNT activator B, and we can volitionally predominate the magnitude of acceleration and activation rate of PNT activation source by the control of action rate or strength of PNT activator to PNT activation source, the paper introduces macrostructure design of tyre model of PNT engine as following

针对这样的客观技术要求并基于这样的假定事实——"我们己发现一种可用于PNT应激物质源的原子态PNT惠合系α在激励信号β的作用下沿一定方向加速运动，而且我们可以通过直接调控激励信号β对原子态PNT惠合系α的工作强度来控制PNT惠合系α的被激励程度或被激加速度大小和激活率"，本文着重介绍PNT引擎的宏观结构设计——PNT引擎之轮胎结构如下

I.Two clearly different variations of the measured exciton lifetime in GaAs/AlGaAs system with well width are observed,and can be attributed to the change ofthe exciton effective volume and the overlap integral.

在GaAs/AlGaAs系统，我们观察到激子寿命随阱宽变化的两种明显不同的趋势，而在InGaAs/GaAs系统，测量结果发现，激子寿命几乎与阱宽无关。
