laying intensity 中文意思是什麼
laying intensity
解釋
產蛋強度-
In the egg laying industry, the bodies of laying birds often suffer from deteriorated resistance to disease, short duration of the peak period of egg laying time and low rate of egg production due to the laying houses incomplete disinfection, poor sanitation, low - intensity light and lacking ventilation
在蛋禽飼養中，由於禽舍消毒不徹底，環境衛生較差，光線不足，通風不暢等原因，導致蛋禽機體抗病能力較差，產蛋高峰期持續時間較短，產蛋率降低。 -
A detailed literature review of physiological effects of light on laying hens was undertaken, with reference on the effects of light intensity, photoperiod and light color on the ontogenetic, survive, feeding, growth, reproduce abilities, in order to provide some information for research work and application in this field in the future
摘要本文綜述了光照對蛋雞生理學特徵影響的研究進展，主要涉及光照周期、光照強度和光色對蛋雞個體生長發育、存活、攝食、生長、繁殖等方面的研究進展，以期為我國進行該領域的研究和指導養殖實踐提供一定的參考。 -
We analyes post - tensioned prestressing properties and comparing with practiced results. we analyse one - way precast slab sandwich negative moment section resistant crack properties and two - way precast slabs sandwich under plane resistant crack at unprestressed section and second - prestressing propties. we compare canceling bonded reinforcement with laying on bonded reinforcement resistant crack properties and deformation. auxiliary lab include : concrete resistant pollution intensity. concrete resistant compressing intensity and elastic modulus, compare with results of code. analyse sandwich ' s strain and long - time stress, strain and introduce a new method through theory calculating long - time stress and strain
配套的試驗研究有：混凝土的抗拉強度和彈性模量試驗及混凝土的抗壓強度和彈性模量試驗，混凝土的極限抗拉強度和極限拉伸應變試驗，並與《混凝土結構規范》 （ gb50010 - 2002 ） ，結果進行了對比；單塊夾層板放張階段的彈性應力、應變分析和長期應力、應變分析，並詳細介紹了按混凝土徐變理論進行長期應力、應變分析的方法。
