家禽生产开始于有组织的商业生产,经历了饲料配方的结构优化过程。随着对家禽营养物质和能量需求的深入了解,配方设计也越来越接近家禽生产对养分的需要。随着时间的推移,已开始应用可利用养分和能量,特别是用于弥补配方中有变化的原料中可消化养分的变化作为配方依据。建议配方中应提供准确的原料养分可消化组分的成分,而不仅仅是总能和总养分,例如在做配方时选用非植酸磷而不是总磷,这是因为总磷中有一部分是不能被家禽利用的植酸磷。用可消化氨基酸是因为家禽对不同的原料氨基酸消化率有差异。而能量通常采用ame.示,即已被家禽消化和代谢的能量。在家禽饲料中添加外源酶能提高经济效益,尤其是添加的外源酶与饲料中不可消化的成分相匹配时,就形成酶-底物复合物,随后在胃肠道内起化学反应,降解所产生的养分才能被吸收和代谢。通常线性饲料配方软件的数据库会对原料不可消化组分的量进行限制。因为没有足够的数据用于准确计算出饲料中受限制物质的量,添加外源酶的好处就无法显现出来。本文目的是提供一种方法,将家禽潜在的不可消化物质的所有分子应用于营养数据库并计算出其含量及评估外源酶降解效率。

正视眼与近视眼的眼球形状

世界核心医学期刊文摘（眼科学分册） 2005年第2期1卷 29-29页

作者： Atchison D.A. Jones c.E. Schmid K.L. 陈立军 School of Optometr y QUT Kelvin Grove Brisbane QLD 4059 Australia

PURPOSES. To determine axial, vertical, and horizontal eye dimensions in myopi c and emmetropic eyes by using magnetic resonance imaging (MRI) and to relate th ese to different ocular expansion models of myopia development. METHODS. The int ernal length (cornea to retina), height and width (both retina to retina) were m easured in emmetropic and myopic eyes (up to-12 D) of 88 participants aged 18 t o 36 years. Participants were positioned supine in a clinical MRI scanner. The f ixation target was imaged straight ahead of the subject by an overhead 45°incli ned mirror. Eye images were acquired with a 7.5 cm receive-only radio frequency surface coil. Axial (horizontal through middle of eye) and sagittal (vertical t hrough visual axis) sections were taken with a T1-weighted fast spin-echo sequ ence. RESULTS. With an increase in myopic refractive correction, myopic eyes bec ame.much larger in all three dimensions, but more so in length (0.35 mm/D, 95%c onfidence interval cI 0.28-0.40) than in height (0.19 mm/D, 95%cI 0.09-0.29 ) and more so in height than in width (0.10 mm/D, 95%cI 0.01-0.20). Based on h eight and length dimensions,25%and 29%of myopic eyes exclusively fitted global expansion and axial elongation models, respectively. Based on width and length dimensions, 17%and 39%of myopic eyes exclusively fitted the global expansion a nd axial elongation models, respectively. cONcLUSIONS. Although there are consid erable individual variations, in general myopic eyes are elongated relative to e mmetropic eyes, more in length than in height and even less in width. Approximat ely a quarter of the myopic participants fitted each of the global expansion or axial elongation model exclusively. The small proportions are due primarily to t he large variability in the dimensions of emmetropic eyes.

NPN型半导体致冷结构

沈阳工业大学学报 2001年第5期23卷 420-422页

作者：揣荣岩孟丽囡汲晓欧董海青沈阳工业大学信息科学与工程学院辽宁沈阳110023 哈尔滨电表仪器厂黑龙江哈尔滨157500

提出了一种新型的半导体致冷结构,并对其致冷机理进行了理论分析,由于与晶体管结构相同,且工作在放大状态下,因此这种半导体致冷具有控制功率小,灵敏度高等优点,同时其制造工艺还可与集成电路相兼容.
