Deficiency of selenium in chicken decreases immunity of erythrocyte and the regulation of erythrocyte to the specific immunity, which includes the decrease of the phagocytic ability of phagocyte, the eliminating ability of circulatory immune complex, the ability of identifying organism, carrying antigen and the immune regulation effects in the activation course of T lymphocyte, B lymphocyte, NK cell alexin, which decreases immunity of organism.

雏鸡硒缺乏降低了红细胞免疫力；同时降低了红细胞对特异性免疫的调节作用，主要表现为降低了吞噬细胞的吞噬能力、清除循环免疫复合物能力、机体识别和携带抗原能力以及对T、B淋巴细胞、NK细胞补体的活化过程的免疫调节作用，结果使机体免疫力下降。

Apha amylase was difficult to bind with the substrate, ther fore the hydrolysis rate decreased with time.

此外，当酶水解发生到一定程度，淀粉分子链长度变得很短。alpha淀粉酶与酶作用物的结合较难，因此水解速率随着反应的进行时间下降。

The viability of SAS cells decreased obviously because of the raised of the ANE and arecoline, especially in the concentration of 800 ug/ml and 0.8 mM respectively.

在细胞的存活性实验也发现，随著槟榔子萃取物与槟榔素浓度提高，分别在800 ug/ml与0.8 mM浓度时，SAS细胞存活率会有明显下降的情况。

Copolymers having about 2 mol% of comonomer appeared to have higher isotacticity as calculated from methine group signals in the 13C-NMR spectra.

经13C-NMR分析，随著共聚单体IR在共聚物中的摩尔分数的增加，共聚物的全同规整度增加，达到一定值后又呈下降趋势。

Copolymers having about 2 mol%of comonomer appeared to have higher isotacticity as calculated from methine group signals in the 13C-NMR spectra.

经13C-NMR分析，随着共聚单体IR在共聚物中的摩尔分数的增加，共聚物的全同规整度增加，达到一定值后又呈下降趋势。

The results showed that appropriate amount of potassium fertilizer could increase the contents of soluble solids and vitamin C in harvest, and reduce titratable acid content in fruits; slow down the reduction of fruit titratable acid content under refrigeration, inhibit the increase of the content of soluble solids and losses of vitamin C, and well preserve the quality of fruit and its storability.

结果表明适量增施钾肥能提高无花果采收时可溶性固形物含量和维生素C含量，降低果实可滴定酸含量；减缓冷藏期间果实可滴定酸含量的下降，抑制果实可溶性固形物含量的上升和维生素C的损失，较好地保持了果实的品质，提高了果实的耐贮性。

In pH2.5 potassium hydrogenphthalate buffer solution, a supermolecular can be developed betvveen Cu-TZAMB complex and DNA, which can decrease the cathodic peak of this complex. This supermolecular complex was testified to be intercalating bound to the DNA by cyclic voltametric method, salt effect and the UV-VIS spectra.

通过循环伏安法、盐效应以及紫外-可见吸收谱证实了是由Cu-TZAMB络合物与DNA形成一种插入式的电惰性结合物而使其峰电流下降。

Both radicals and peroxides, which were produced during the irradiation in air, can initiate graft copolymerization.

研究了不同接枝量接枝共聚物的结晶过程，以球晶结构变化解释了接枝共聚物断裂强度的下降。

The research employed nylon bag implantation and in vitro fermentation techniques. With the procession of in vitro fermentation, anaerobic fungal population density in the cultures were shown to increase, with the largest fungal populations growing on ryegrass leaves, ryegrass stem and straw occurring after 48 h of incubation.

结果表明，随体外发酵的进行，真菌数量逐渐增加，以黑麦草叶、黑麦草茎、稻草秸为底物时，瘤胃真菌数量均在48 h达到最大值，且真菌数量的最大值随底物木质素含量的上升呈下降趋势。

Its thermal resistance and moisture-vapor resistance drop considerably in relation to the cotton fabrics of same specifications.

整理后棉织物的热阻和湿阻相对于同规格的棉织物都有所下降，水或汗液从整理面导向织物另一侧时，能快速扩散、蒸发，使织物内层保持相对干爽。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
