We present several laser sources dedicated to advanced microwave photonic applications.A quantum-dash mode-locked laser delivering a high-power,ultra-stable pulse train is first *** measure a linewidth below 300 kHz at a 4.3 GHz repetition rate for an output power above 300 mW and a pulse duration of 1.1 ps after compression,making this source ideal for microwave signal sampling applications.A widely tunable(5–110 GHz),monolithic millimeter-wave transceiver based on the integration of two semiconductor distributed feedback lasers,four amplifiers,and two high-speed uni-traveling carrier photodiodes is then presented,together with its application to the wireless transmission of data at 200 Mb∕s.A frequency-agile laser source dedicated to microwave signal processing is then *** delivers arbitrary frequency sweeps over 20 GHz with high precision and high speed(above 400 GHz∕ms).Finally,we report on a low-noise(below 1 kHz linewidth),solid-state,dual-frequency laser *** allows independent tuning of the two frequencies in the perspective of the implementation of a tunable optoelectronic oscillator based on a high-Q optical resonator.

Behaviour of Roofing Materials Facing to Micro-Organisms

引用

Green and Sustainable Chemistry 2013年第1期3卷 8-14页

An accelerated water-streaming test was used to evaluate several roofing materials regarding their behavior to colonization by algae, by closely reproducing the phenomenon of natural biological soiling. A set of roofing materials with defined physical and chemical characteristics was thus investigated against the colonization by algae. Porosity, roughness and chemical composition showed to be factors of influence in the establishment of those micro-organisms.

饲料与畜牧 2019年第9期 44-46页

作者：张振玲 Mathilde Ramillien Joelle faugeron 徐州生物工程职业技术学院动物工程系

本文针对以下几个有关猪甜味剂的主要问题:①食物吃起来感觉甜是什么原因?②猪的口味会随时间改变吗?③猪对甜味的感觉与人相似吗?④'甜'对猪的口腔和肠道分别有什么作用或影响?⑤'甜'对肠道也起作用吗?⑥增甜饲料到底有何非比寻常的作... 详细信息

本文针对以下几个有关猪甜味剂的主要问题:①食物吃起来感觉甜是什么原因?②猪的口味会随时间改变吗?③猪对甜味的感觉与人相似吗?④'甜'对猪的口腔和肠道分别有什么作用或影响?⑤'甜'对肠道也起作用吗?⑥增甜饲料到底有何非比寻常的作用?言简意赅地从细胞水平上揭示了猪感觉甜味的机理,同时介绍了甜味剂对猪(主要是仔猪)的作用,最后通过试验数据说明甜味剂对于仔猪的生长性能和饲料转化率均有显著的影响。
