1. Information Processing Definition of Information processing All operations exerted to the information itself for its better utilization Information processing is necessary because most of the information in its original form may not be good for use. Thus information processing is the basis of later operations Two categories of information processing: 1)Shallow Level of Information Processing 2)Deeper level of Information Processing

Problems to be concerned with 1. How should we define the concept of Information 2. What are the typical features of Information compared with matter and energy 3. What are the relationship and difference between Shannon Information and comprehensive Information 4. How to reasonably classify Information 5. How to properly represent Information

1.1 Information science Definition of information Science Information Science is a trans-disciplinary science with information as its object in study; the laws in information process as its content information methodology as its approach; and the strengthening human information functions particularly the intellectual ability, as its goal

1范围 本法适用样品中硫离子浓度范围101~103mg/L,检测下限浓度为0.2mg/L经六个以上实 验室验证,本法可用于制革、化工、造纸、印染等工业废水以及地表水中硫离子含量的测定。 工业废水大多色深、浑浊,含有机物、阳离子、阴离子,成份复杂;且硫离子极易被氧 化,不易保持稳定的浓度

1范围 电位滴定法适用于一般地面水和地下水。水样中的色度、浊度过高不干扰测定。 如水样的矿化度高于1000mg/L,亚铁离子或铝离子含量超过10mg/L时,会对测定产生 干扰,可于滴定前加入1mL50%(m/V)酒石酸钾钠溶液,以消除干扰。铬、铜、胺类、氨、硼 酸盐、亚硝酸盐、磷酸盐、硅酸盐、硫化物和无机酸类及强酸弱碱盐类均会影响测定
