The results show that this strain was a typical acidophile with optimal growth pH being 2.0 for hypha and pH 3.0-4.0 for the spore germination. Peptone was the most suitable nitrogen source which helped produce xylanase induced by xylan during stationary phase. The resultant xylanase reacted best at 50℃-55℃ and pH 3.5, and had activities 70% after 60 min maintenance under optimum reaction conditions.

结果表明：实验菌株嗜酸，菌丝生长最适pH为2.0，孢子萌发生长适宜pH为3.0-4.0；木聚糖诱导菌体在生长稳定期大量产生木聚糖酶，蛋白胨是菌体产酶的适宜氮源；菌株所产木聚糖酶属于酸性木聚糖酶，反应最适pH3.5、最适温度50℃-55℃，在最适反应条件下保温60min，残余酶活仍接近70%，适用于较强酸性的高温加工环境。

You should have fish twice a week because it is a very good source of omega 3 fatty acids.

你应该每周两次鱼，因为它是一个很好的来源，欧米加3不饱和脂肪酸。

But because of the fake source address, there is no ACK return.

但是由于伪造源地址的原因，不会有ACK返回。

objectiveto keep the stability of issr_pcr and reliability of genetic diversity, sibship analysis and source assessing for aconitum carmichael dexb.

目的保证乌头issr-pcr的稳定性、提高对乌头遗传多样性，亲缘关系分析、种质鉴定的可靠性。

This thesis compares the characteristics of secondary batteries used for the underwater system in order to find a proper power source that is suitable for the system. Moreover, the low-cost integrated circuit and buck-type converters are used to obtain the required voltage levels for the devices in the system such as the underwater acoustic modem, single board computer and vertical line array hydrophone with condition amplifiers.

中文摘要本文针对常用於水下遥测系统之二次电池进行特性比较，以选用适合作为其电源之电池，再将电池输出电压经低成本之类比IC与降压型转换器转换至符合本系统设备如水下数据声传器、水下遥测单版电脑与垂直阵列麦克风讯号放大器等所需之电压等级。
