Methods Proteins existed in adult Schistosoma japonicum membrane were extracted by Triton X-100 and purified through reverse-phase high performance liquid chromatography,and the main protein peaks were then collected separately. 125 I-LDL of human plasma as the ligand, through the radioautography and radioligand binding assay, the protein which can bind human serum 125 I-LDL specifically was identified.

To divide the range of a variable into a finite number of non-overlapping intervals that are not necessarily of equal width, and to designate each interval by an assigned value within the interval, e.g., a person's age is for most purposes quantized with a quantum of one year.

把一个变量的取值范围分成有限个不重叠的区间，这些区间的大小不一定相等，并给每个区间指定一个属于该区间内的值。例如，人的年龄在大部分情况下是用一年这个量［区间］来量化的。

As an often used physical model with good theoretical and practical values, StreeterPhelps model has been widely used to study water quality. However, in some special water areas the utilitization of StreeterPhelps model has some limitation as confirming reaeration coefficient often comes from tests in rivers with fast water flow speed with no consideration of wave effects. Furthermore, in practical research in Three Gorges Reservoir, the changing rule of COD appears abnormally. In some water areas far from pollution source, the value of COD changes with time, but does not follow the exponential attenuation rule. This phenomenon can not be explained by former modified StreeterPhelps model.

StreeterPhelps模型是目前进行河流水质研究常用的物理模型，具有良好的理论和实用价值，然而在某些特定水域，该模型的应用受到限制，主要原因是复氧系数的取定多在水流速度较大情况下得到的，而未考虑水面波动对复氧系数的影响，另外，在实际研究过程中发现三峡库区COD变化的规律出现异常：在离排污口相当远的水域，COD随时间变化趋势并不是指数衰减，而是在某个常值附近微小摆动，以往很多修正过的StreeterPhelps模型都无法解释这个现象。
