The polymer particles have linear response to aminoacetic acid from 5.0×10-6 to 7.0×10-5 mol/L with a correlation coefficient of 0.997 3, a detection limit of 1.4×10-6 mol/L and a recovery ratio in the range of

聚合物颗粒悬浮液的相对荧光强度对氨基乙酸的浓度为5.0×10-6~7.0×10-5 mol/L时有线性响应,线性相关系数为0.997 3,检测限为1.4×10-6 mol/L,回收率为

The effects of solvent, temperature, and shaking-time on the content of cinnamaldehyde in the microcapsules were also studied.

以桂皮醛为客体,β-环糊精为主体,研究了乙醇体积分数、温度、振荡时间对悬浮液法制备微胶囊中桂皮醛含量的影响。

The best relative effect of cross-protection was found when spore concentration of Cladosporium cucumerinum was adjusted to 1×10^2 spores/ml for 48 h interval. And it was much better in resistant cultivars than in susceptible ones. Meanwhile, after challenged by Corynespora cassiicola the cucumber induced by Colletotrichum orbiculare produced great resistance to brown-spot, but that increased the development of anthracnose.

在黑星病菌对霜霉病菌的诱导作用中,以浓度为1×10^2个/ml的黑星病菌孢子悬浮液的诱导效果最好,诱导间隔期为48h黄瓜黑星病菌对霜霉病的交互保护作用最明显,抗性品种的交互保护作用明显好于感病品种;炭疽病菌可诱导黄瓜有效抑制褐斑病的发生,但挑战接种褐斑病菌后,却促进了炭疽病的发生。

The effect of 6 fungicides on germination of conidia of the strain Ma83, Metarhizium anisopliae, in different time was studied.

Different kinds of flocculants have different capabilities. The flocculants produced by Aspergillus parasiticus is not steady for heat. The flocculating effect is best at acid conditions, and it is not acute for Ca〓. The flocculant can decolorize soluble dyestuff, even the active gorgeous red X-3B which is difficult to be decolorized, the decolor rate is 62. 1%. The flocculant produced by A-9 is steady for heat. It can flocculate Gaolin suspension well without synergistic effects of CaCl〓, and the dose is only 0.05ml/L. The obvious character of A-9's medium cultured for 3days is very viscosity, and viscosity is a mark for microorganism producing microbial flocculants.
