通過測定減水劑的水泥凈漿流動度及流動度損失宏觀反映合成減水劑共聚體pc的性能，研究結果表明： （ 1 ）鏈轉移劑是控制共聚物分子量影響共聚體pc性能的主要因素之一，在選擇鏈轉移劑zy 、用量為8 aa時的作用效果最佳。 -
It was found that three polysaccharides had no effect on growth performance of broilers relative to the control during the 28day trial, but affected the immunity in a different way ; they all increased bursa index significantly ( p < 0. 01 ), achyranthan ( ach ) also increased hi titers significantly ( p < 0. 05 ) and lymphocyte proliferation ( p = 0. 12 ), three polysaccharide also significantly affected serum index, they increased serum albumin and calcium concentration significantly. the result indicates that smaller molecular weight polysaccharide may be more effective than larger ones in stimulating immunity when administered orally
研究發現：三種多糖對肉雞生產性能無顯著影響，但對免疫功能有一定影響：三種多糖均顯著提高了法氏囊指數（ p 0 . 01 ） ，牛膝多糖還顯著提高了肉雞新城疫抗體滴度（ p 0 . 05 ） ，對外周血淋巴細胞轉化率也有一定影響，但差異不顯著（ p = 0 . 12 ） ，三種多糖對肉雞anae陽性率及脾臟、胸腺指數均無顯著影響。
