When the CPS of (220) is high or the CPS of (311) is low, the estimating results are easy to be more than measurement, and vice verse.

当(220)的CPS值高时或(311)的CPS值低时，估算值比测量值高，反之亦然。

Moreover, according to element compositions in mussels, these fishes were divided into three groups. The first group was characteristic with low phosphorus and high C/N ratio including Engraulis japonicus, Conger myriaster and Scomberomorus niphonius. The second had low phosphorus and low C/N ratio including fishes such as lower and middle carnivores such as Pseudosciaena polyactis, Platycephalus indicus and Argyrosomus argentatus. The third included some cold temperatefishes such as Scomberomorus niphonius and Liparis tanakae that were high phosphorus and low C/N ratio.

此外，根据鱼类的肌肉元素组成，将鱼类分为3类：第一类的主要特征为低磷、高C／N比值，主要包括鳀鱼、星康吉鳗和带鱼；第二类种类最多，主要包括小黄鱼、鲬和白姑鱼等中、低级肉食性鱼类，其元素组成特征为低磷、低C／N比值，；第三类的主要大泷六线鱼、细纹狮子鱼等冷温性鱼种为主，元素组成特点为高磷、低C／N比。

Phosphate use efficiency of Arundo donax Linn with iron plaque was 16.5% more than that of without,31.4% for typha latifolia .

This paper analyzes the trends and variations of cross-section profile parameters in lower Yellow River with the methods of time series analysis. The analysis results show that since 1950s, cross-section profile parameters in lower Yellow River have change with trend, especially after 1990s, the bankfull discharge and bankfull area all show decreasing trends at all the four stations. The bankfull width at Huayankou, Gaocun and Lijin station and the average depth at Huayuankou and Aishan station and the maximal depth at Gaocun station show decreasing trends while the bankfull water level at Gaocun and Aishan station and width-depth ratio at Aishan station show increasing trends.

本文采用时间序列分析的方法对黄河下游河道断面形态参数变化趋势及其变异点进行了分析，分析结果表明从20世纪50年代以来，断面形态参数发生了趋势性变化，特别是90年代以来各站平滩流量和平滩面积均有显著的下降趋势，花园口站、高村站和利津站平滩河宽出现了显著下降趋势，花园口站、艾山站平均水深显著下降，高村站和艾山站的平滩水位显著抬高，艾山站的宽深比也有显著增大的趋势。

It can be seen from above mentioned that a high performance concrete suitable for dam project can be obtained with high belite cement.
