Good thermal stability and self-extinguishing behavior was observed with the cured polybenzoxazine resins. Second, furan-containing benzoxazine monomers, P-FBz, BPA-FBz, and 4FP-FBz were prepared using furfurylamine as a raw material. Formation of furfurylamine Mannich bridge networks in the polymerizations of P-FBz and BPA-FBz increased the cross-linking densities and thermal stability of the resulting polybenzoxazines. P-FBz and BPA-FBz- based polymers also exhibited high glass transition temperatures above 300℃, high char yields, and low flammability with a limited oxygen index value of 31. The dielectric (Dk3.21–3.39) and mechanical properties (high storage modulus of 3.0–3.9 GPa and low coefficient of thermal expansion of 37.7– 45.4 ppm) of the P-FBz and BPA-FBz-based polymers were superior or comparable to other polybenzoxazines. 4FP-FBz used for polybenzo- xazine modification by means of formation of benzoxazine hybridation with P-FBz.

第二部份以2-呋喃甲胺为起始物，制备了P-FBz、4FP-FBz与BPA-FBz 三个含呋喃官能基之氧代氮代苯并环己烷的单体；BPA-FBz与P-FBz於开环聚合中形成之Mannich bridge网状结构有效地提升聚氧代氮代苯并环己烷聚合物之交联密度与热安定性；Poly与Poly具有大於300℃之玻璃转移温度、高的焦炭生成率与具有31之极限氧指数(Limited oxygen index， LOI)的难燃性特质，Poly与Poly之介电常数(Dk=3.21~3.39)与机械性质[3.0~3.9 GPa的储存模数与37.7~45.4ppm之低热膨胀系数( Low coefficient of thermal expansion， Low CTE)]均较其他聚氧代氮代苯并环己烷为优；4FP-FBz具有低之介电常数(Dk=2.7)，以其作为降低介电常数之反应型改质剂，与P-FBz混成，证实可有效地降低Poly的介电常数。

Photodynamic action of methionine-riboflavin mixture with a high level of reactive oxygen species production is a powerful microbicidal system.

METHODS:The micronucleus test of Vicia faba root tip cell was used to detect the water quality,and to survey the chemical oxygen demand.The micronuclear rates and Pollution Index were determined and the F-test was used to evaluate the difference in micronuclear rates among different samples.

材料与方法：用蚕豆根尖细胞微核技术对各采样点水样进行监测，并对各水样进行化学需氧量(chemical oxygen demand，CODcr)的测定，统计分析各采样点水样的蚕豆根尖细胞微核千分率及污染指数。

Some water samples from intakes and outlets of 3 wetland pond beds growing Phragmites communis Trin, Typha angustifolia and Cyperus alternifolius were respectively taken for monitoring and contrasting 5 main water quality indexes including dissolved oxygen, chemical oxygen demand, biochemical oxygen demand in 5 days (BOD5), total nitrogen, and total phosphorus month by month all year around, so as to discover influences of different plant species on water purification efficiency.

摘 要：通过对成都活水公园人工湿地中的3种优势挺水植物所在塘床进出水口的5个主要水质指标：水中溶解氧（dissolved oxygen， DO）、化学需氧量（chemical oxygen demand， CODcr）、5日生化耗氧量（biochemical oxygen demand in 5 days， BOD5）、总氮（total nitrogen， TN）、总磷（total phosphorus， TP）的全年逐月对比监测，探索不同植物种类对污水净化效率的影响，并对湿地中不同植物塘净化效率产生差异的原因作了较全面的分析讨论。

Fter different detraining cycles on the physiological performance, the detraining cycles will be reflected different degrees of impact. We found that the strength and endurance of athletes in detraining has reduced the capillary density, oxidative fibers, slow-twitch muscle. On the other hand, AVO2-diff, oxygen enzyme decline in the number of mitochondria, the change of muscle fiber types and reduced neuromuscular control in long-term detraining. In cardio-respiratory fitness, particularly in endurance athletes among blood flow, plasma volume, and cardiac output's decline are the most conspicuous. After hormone and metabolic's short term and long-term detraining, we found that growth hormone, testosterone, cortisol, respiratory exchange rate, showed a decline in insulin sensitivity, it will directly affect the exercises performance. Further more, the exercises performance and physiological benefits could have been completely eliminated.

bstract 不同周期停止训练后，对生理表现将反映出不同程度之影响，其中发现肌力性与耐力性运动员在短期停止训练后，毛细血管密度、氧化纤维、慢缩肌呈现减少情形；反观长期停止训练后，将会使动静脉血含氧差异(arterial-venous oxygen difference， AVO2-diff)、氧化酶粒腺体数目下降与肌纤维型态之改变，而减少神经肌肉控制能力、在心肺适能方面，尤以耐力性运动员在血流量、血浆量、每跳输出量、最大心输出量下降情形最明显；而贺尔蒙与代谢在短期与长期停止训练后，发现生长贺尔蒙(growth hormone， GH)、睪固酮、可体松、呼吸交换率、胰岛素敏感性均呈现下降情形，这些情形将直接影响其运动表现之发挥，甚至使先前获得之运动表现与生理效益完全消失。
