Based on Prandtl's momentum transportation, this paper calculates in detail the physical quantities such as eddy viscosities, and ratio of eddy viscosity to motion viscosity, total stresses with respect to relative position in three regions of viscous sub-layer, buffer layer, and main turbulent stream for non-Newtonian fluid flowing turbulently in ducts, which according to Karman's three layer models and measurement of fluid parameters in evaluation apparatus, discusses the influence of polymer drag reduction on flowing properties of non-Newton fluid, analyzes quantitatively principle of turbulent reduction phenomenon and condition of increasing reduction rate.

摘要以普兰德动量传递理论为基础，按照卡门的三层模型，通过室内模拟环道用0号柴油及加入减阻剂在圆管内的流动参数的测定，计算了非牛顿型流体管内湍流边界层的层流内层、过渡层、湍流中心的涡流粘度，涡流粘度与运动粘度比、总应力随相对位置的变化等定量参数，探讨了高分子减阻剂对非牛顿流体流动特性的影响，对湍流减阻现象的机理与增大减阻率的条件进行了定量分析。

Diagnostic tests include the arterial blood gas, and nitroprusside test for acetoacetate (used qualitatively, not quantitatively, because it always underestimate s the severity of the acidsis).

诊断实验包括动脉血气分析、以及测定乙酰乙酸的硝基实验（因常用于估计酸中毒的严重程度，只作为定性实验而不是定量的）。

METHODS: The concentration of ozone that was transmitted by ozone generator at different time was determined by using iodine titrimetric method. According to the bactericidal assay of quantitative vehicle, the bacteria on the ozonized vehicles and unozonized vehicles was washed, 50μl eluant was seeded on the TSA plates. The TSA plates were put into the anaerobiotic incubator (90% N2, 10% CO2, 37℃). After 24 to 48 hours, the CFU on the plate was counted.

用碘滴定法测定打开臭氧发生器不同机组及不同时间时的臭氧浓度，按载体定量杀菌试验，将经臭氧作用的载体与相同环境下未经臭氧作用的载体上的细菌洗下，各取洗脱液50μl，接种于TSA平板并置厌氧箱(90%N2， 10%CO2， 37℃)培养24~48h后，进行活菌菌落计数。

Results Red peony root,rhubarb,chinese white olive,cape jasmine fruit etc.had high binding capability with LPS in fortytwo Chinese herbs;It was oberserved that red peony root,rhubarb and chinese white olive still had high effective component for antiendotoxin by incubation with endotoxin.

结果 在筛选的42种中草药中，观察到赤芍、大黄、青果、栀子等中药能与Lipid A高亲和力结合；通过与内毒素作用后的二次检测，发现赤芍、大黄、青果等中草药含有较高Lipid A结合的有效成分，定量内毒素中和实验的测定结果与生物传感器的定性检测结果一致。
