【摘要】欣赏音乐是快乐的，把玩音响是有趣的。

单从器材的角度来看，无所不
极的Hi—End器材固然可以带来力攀峰顶揽胜景般的激动和震撼。

但是内涵深厚
的Hi—Fi器材同样也能给人予闲坐庭苑赏雅筑似的淡静与恰然。

MYRYAD
MI120合并晶体管式放大器和AE LINEAR three落地箱，带给我的就是这种感受。

中国农业丈学博士学位论文第一章绪论液层内，直到试液和此极薄液层内氨气的分压相等。

氨气的压力可由ｐＨ／ｍＶ计测量溶液电位得到，由此再通过校正曲线直接读取被测粪样中铵态氮的含量。

氨电极法对于铵态氮的测量结果与标准实验室法的结果几乎相同。

由于氨电极的电极膜容易老化，操作过程复杂，且仪器价格贵（８００—２０００美元），推广有一定难度。

４．氮量计法１９８３年瑞典ＡＧＲＯＳ公司开发了一种氮量计（ＮｉｔｒｏｇｅｎＭｅｔｅｒ）（Ｃｈｅｓｃｈｅｉｒ，１９８５）（图１．５），用于预测畜禽粪便中氮的含量。

该装置由一个密闭的不锈钢反应室和压力表组成。

通过试样与强氧化剂氯酸钙反应生成氮气导致的压力变化测定氮含量（ＳｅｒｇｉｏＰｉｃｃｉｎｉｎｉ，１９９１）。

３Ｃａ０２Ｃ１２＋４Ｎ地＋＋４０Ｈ一３ＣａＣｌ２＋２Ｎ２ｔ＋１０Ｈ：Ｏ（ｔ－２８）式中氮气的产生量可由理想气体方程推导出来：ＰＶ＝铂ＲＴ（１—２９）其中：Ｐ——压力（Ｐａ）；ｖ——体积（ｍ５）；ｎ——氨原子量；Ｒ——气体常数：Ｔ——绝对温度（Ｋ）。

１９８７年联邦德国的Ｒｉｍｕ—Ｌｕｆｉｕｎｇｓｔｅｃｍｎｉｇ公司开发了Ｑｕａｎｔｏｆｉｘｎ－Ｖｏｌｕｍｅｔｅｒ（ＳｅｒｇｉｏＰｉｃｃｉｎｉｎｉ，１９９１）（图１．６），其基本原理与ＡＧＲＯＳ公司的产品基本相同。

不同之处在于Ｑｕａｎｔｏｆｉｘｎ．Ｖｏｌｌｌｍｅｔｅｒ使用塑料代替了不锈钢制作反应室内胆，使用与试样质量５：ｌ氯酸钠Ｏｑａｏｃｌ）－与３０％氢氧化钠溶液的混合溶液做反应剂，其反应方程式是：３ＮａＯＣＩ＋２ＮＨ４＋＋２０Ｈ‘－＊３ＮａＣＩ＋５Ｈ２０＋Ｎ２ｔ（１·３０）氮气的产量可以通过量筒测量由产生的氨气排挤出的水的体积计算。

图１—５ＡＧＲＯＳ氮量计以上两种设备的价格都在３３０美元左右，图１—６Ｑｕａｎｔｏｆｉｘ氮量计单个样本检测费用在１美元左右。
