绪言: 关于合金元素对铸态球墨铸铁机械性能的影响,已经做过许多研究,***等做了广泛的总结。对铁水孕育增加了晶核数目,因而也增加了共晶团数目。适当的孕育能防止形成过冷石墨和菜氏体碳化物。但孕育作用仅能维持一个较短的时间,因此,应尽量缩短孕育和凝固之间的时间。因而使用了瞬时孕育法。此法可以在浇注时加孕育剂或直接把孕育剂加在浇口杯里。

在由 S-1型磁心材料制成的线选法存贮器的设计中基本问题是实现一个能满足多种性能要求的读出放大器。一般要求读出放大器对双向信号均具有稳定的增益,信号传送的延时小,避免直流电平的偏移,在数位脉冲(或禁止脉冲)干扰后的短时间内能恢复,鉴别电平稳定等。虽然有过很多有关读出放大器设计的文章,但就作者所知,对于一个处于“最坏输入形式”——一长串单向脉冲中夹有一串数位脉冲干扰下的4—6微秒的存贮器来说没有一篇特别合适的。本文讨论了对于具有所要求的存取周期的线选法存贮器的读出放大器的基本要求,给出了读出放大器的新线路、它的作用及设计。重点放在技术的改进和线路的提出上。对设计时采用过的几种其它方法也做了扼要介绍。作者对读出问题的可能发展途径也进行了探讨。

The present study aimed to determine whether natural dehydrated feed (DNf) can replace dry extruded feed while preserving the required daily intake, nutrient digestibility and benefits for immunity and antioxidant response in cats. The animals were divided into two groups of seven animals each. One group received DNf, and the other consumed commercial extruded dry feed (DCf). The experiment lasted 45 days and we measured daily consumption and collected blood and feces samples. The animals in the DNf group showed greater digestibility of fiber and mineral matter than DCf. Cats in the DNf group had a higher volume of feces. DNf cats had lower leukocyte and granulocyte counts and cholesterol levels. Serum enzymatic antioxidant responses and non-enzymatic were higher in DNf cats. Cats in the DNf group showed lower serum acute phase proteins in addition to a tendency toward a higher concentration of transferrin than in the DCf group. fecal Escherichia coli and total coliform counts of cats fed DNf were higher than DCf. We conclude that the daily consumption of cats is adequate. This feed had greater digestibility of fiber and mineral matter, in addition to an improvement in antioxidant and immunological responses.

We determined whether the inclusion of 100 g/kg dry matter of grape pomace silage (GPS) and grape pomace bran (GPB) as substitutes for other traditional fiber sources in the diet of steers (Charolais x Nellore) would improve carcass characteristics, meat quality and composition, and shelf life. Twenty-four animals (248 ± 19.32 kg of initial body weight) were fed a high concentrate diet for 121 days. Carcass characteristics were measured, and the longissimus dorsi muscle was analyzed for fatty acid (fA) profile and composition. The meat was sliced and stored in air-permeable packages for 10 days. On each sampling day (d 1, 3, 7, and 10), oxidative stability, bacterial load, lipid and protein oxidation, and staining were analyzed. The experimental diets influenced the pH of cold carcasses only. The GPS group had a higher pH than the control. The GPS and GPB groups showed improved oxidant status (i.e., lower lipid peroxidation and concentrations of reactive oxygen species were in the meat of both groups than in control). On the first day of storage, the antioxidant enzyme glutathione S-transferase activity was more significant in the meat of the GPS and GPB groups than in the control. The bacterial loads in the meat were attenuated by GPS inclusion;there were lower total coliform counts and a trend toward lower counts for enterobacteria in the control group. The diets altered the fA profile of the meat;i.e., the GPB diet allowed for a more significant amount of the n-6 omegas in the meat, while the GPS diet showed a tendency for a more significant amount of n-6 and 9 omegas. Both diets (GPS and GPB) increased the amounts of long-chain fAs. The GPS diet decreased saturated fA levels. We conclude that the dietary treatments GPS and GPB are a promising alternative to maintain meat quality standards throughout in real-world retail conditions. These treatments gave rise to an improvement in the nutritional value of the meat due to the more significant amounts of fAs that im
