ULSI中的铜互连线RC延迟

随着ULSI向深亚微米特征尺寸发展，互连引线成为ULSI向更高性能发展的主要限制因素。由互连引线引起的串扰噪音及RC延迟限制了ULSI的频率性能的提高，同时考虑到电迁移和功率损耗，人们开始寻找新的互连材料；低电阻率的铜互连材料和低介电常数介质的结合可以有效地发送互连线的性能，主要讨论了互连延迟的重要性以及发送和计算延迟的方法。

WC含量对弥散强化铜Cu/WC组织与性能影响的研究

对以WC粒子为第二相的弥散强化铜材料的组织与性能进行了研究。在同样条件下，用机械混料方法制备了不同WC含量的Cu/WC复合材料，分别测定了其密度，电阻率和硬度，结果表明：WC粒子是一种较为理想的弥散相，并且WC体积含量为1.2%时，细小的球形状第二相粒子均匀分布，弥散效果好，材料密度，硬度较高，而电阻率较小，综合性能较好。     

Fire performance of wood (Pinus radiata) treated with fire retardants and a wood preservative

In this work, we co‐formulated an oil‐borne copper naphthenate/permethrin wood preservative system with synthetic polymer‐based fire‐retardant additives prior to the impregnation of Pinus radiata sapwood. We evaluated what effect, if any, the preservative had upon the fire performance properties of the fire retardants and whether the fire retardants impacted on the fungicidal and termiticidal efficacy of the preservative. The fire retardants included halogenated and phosphorus‐based systems. A mass loss calorimeter, in conjunction with a thermopile, was used to measure the time to ignition and the peak heat release rate (PHRR) from which the fire performance index (FPI) was determined. The preservative properties were evaluated using termite and soil‐block decay bioassays. In summary, we found that the rate of fire growth was reduced when the fire retardants were used in combination with the wood preservative. We also found that the PHRR was a better determinant of fire performance than the FPI. The performance of the wood preservative was enhanced against fungal decay and termite attack when used in combination with the fire retardants. The fire retardants also demonstrated some wood preservative properties of their own. Copyright © 2008 John Wiley & Sons, Ltd.     

Evaluation of rapeseed meals in broiler chicks: Effect of iodine supply and glucosinolate degradation by myrosinase or copper

In rapeseed meals (RSM) of a conventional (c) or a newly bred (n) variety 117 or 44 mmol glucosinolates and glucosinolate degradation products per kg dry matter were detected. Soaking meals in aqueous myrosinase or copper sulphate solution and subsequent drying reduced the content of antinutrients by more than 90%. Broiler chickens were fed (i) a glucosinolate-free diet, or this diet in which half the soybean meal was replaced by RSM of various origins and treatment; (ii) untreated cRSM; (iii) cRSM treated with myrosinase: (iv) cRSM treated with Cu (v) untreated nRSM; or (vi) nRSM treated with myrosinase. These diets were administered with or without supplementary iodine. Chickens receiving the iodine-deficient diets with myrosinase-treated RSM showed growth depression, incomplete feathering, leg injuries and severe goitre. In the serum T⁴ could not be detected. Giving myrosinase-treated RSM plus iodine, or giving other RSM diets irrespective of iodine administration, no growth depression was observed. RSM diets without iodine dosage markedly increased thyroid weight: there were no differences between the RSM variants. In contrast to the treatment with myrosinase, in the sera of the chickens fed on untreated RSM or RSM treated with copper T⁴ could be detected, suggesting that in iodine-deficient conditions differences in serum T⁴ concentration between RSM groups indicate a differing anti-thyroid activity. With iodine supplementation the RSM had a significant effect on thyroid weight. The largest thyroids (five-fold heavier) were in the animals with myrosinase-treated cRSM. The untreated cRSM and the nRSM trebled or doubled the thyroid weight, and the myrosinase-treated nRSM trebled it. The thyroid weight of chicks fed cRSM treated with copper did not differ significantly from the glucosinolate-free control. There was evidence that heating the myrosinase-treated RMS produced anti-thyroid compounds; these should be identified in further investigations.
