CHAPTER SIXTEMPERATURE温度; （一）水温测定的环境意义;（二）温度的测量;CHAPTER SEVEN SOLID(固体); 一 SOLID (一)残渣定义与分类： 水蒸发后，残余物质称为残渣。 残渣分为总残渣、总可滤残渣和总不可滤残渣三种。 它们是表征水中溶解性物质、不溶性物质含量的指标。 ;Dissolved Solids—The portion of solids that passes through a 0.45um filter. Undissolved Solids — Portion of solids retained by a 0.45um filter, also called total suspended solids.;Volatile Solids— The portion of solids that could be oxide and volatile under 550°C . It could represent the amount of organic solids in water Total solids consists of dissolved and suspended solids. ;(二)残渣测定方法;（2）总可滤残渣（也称溶解性固体）;（3）总不可滤残渣(也称悬浮物，SS);TS = total solids TSS = total suspended solids TDS = total dissolved solids VSS = volatile suspended solids FSS = fixed suspended solids VDS = volatile dissolved solids FDS = fixed dissolved solids TVS = total volatile solids TFS = total fixed solids;In theory TS = TDS + TSS The TS and TSS fractions are dried at 104o C while the TDS fraction is dried at 180o C. Adsorbed and bound water is almost completely removed at 180o C, while the 104o C drying removes almost no bound water. ; 二 臭与味(odor and taste);（二）臭与味的测定;臭强度等级 ;味的测定;四种味觉的代表物质;（2）阈值法;三 颜色(Color);（二） 色度测定方法;②稀释倍数法;四 浊度 Turbidity;浊度计测定法：浊度计是依据浑浊液对光进行散射或透射的原理制成的测定水体浊度的专用仪器，一般用于水体浊度的连续自动测定。;五 透明度Transparency;①铅字法;Secci disc transparency(塞氏盘透明度) A flat disc lowered into the water by a rope until it is just barely visible. At this point, the depth of the disc from the water surface is the recorded Secci disc transparency. Perform test under matching light conditions and locations. ;②塞氏盘法;六 矿化度;(二)测定方法;七 电导率 Conductivity;（二）测定方法;八 氧化还原电位;9、春去春又回，新桃换旧符。在那桃花盛开的地方，在这醉人芬芳的季节，愿你生活像春天一样阳光，心情像桃花一样美丽，日子像桃子一样甜蜜。7月-217月-21Thursday, July 15, 2021 10、??的志向通常和他们的能力成正比例。22:52:2522:52:2522:527/15/2021 10:52:25 PM 11、夫学须志也，才须学也，非学无以广才，非志无以成学。7月-2122:52:2522:52Jul-2115-Jul-21 12、越是无能的人，越喜欢挑剔别人的错儿。22:52:2522:52:2522:52Thursday, July 15, 2021 13、志不立，天下无可成之事。7月-217月-2122:52:2522:52:25July 15, 2021 14、Thank you very much for
