Aiming at the problem that the seeds picked up by the suction plate of the seed metering device cannot accurately fall into the seed pit opener as well as into the seed pit, an innovated seed metering device on which the seed dropping angle can be adjusted within a certain range and a new testing stand have been developed in accordance with the mathematical calculation model that had 'in accordance with the mathematical calculation model that had been established previously.

本论文根据2BQM-2型气吸式精量铺膜播种机的结构和工作原理，针对该机在实际播种中，吸种盘吸出的种子不能满足准确地落入在膜上滚动开穴的鸭嘴内，并及时地排入到鸭嘴所成的穴孔内的设计要求，进行了一定的试验研究，利用已建立的计算数学模型，设计新的试验台，改进排种器，使排种器的落种角度可以在一定的范围内调整。

It showed that the yeast KD had higher fermentation capacity, gentle fermentation speed, and the produced kiwi fruit wine was clear and transparent with light yellow color and typical kiwi fruit aroma and wine-alcohol bouquet. Furthermore, the produced kiwi fruit wine had high alcohol content to 10.5 %vol, high vitamin C content to 0.94 g/L and low content of reducing sugar, total acid and volatility acid. 48 aroma substances in total were identified including esters (19 kinds, 34.65 %), higher alcohols(5 kinds,15.38 %), fatty acids(6 kinds,13.30 %), and micro-content of alkyls, aldehydes and ketones, which accounted for 97.33 % of total peak area. Such yeast was suitable for kiwi fruit wine brewing. Tran. by YUE Yang

结果表明，酵母KD的单位酵母发酵力较高，发酵速度平缓，所酿猕猴桃酒澄清、透明，色泽浅黄，酒体醇和爽口，具有猕猴桃果香和纯正的酒香，典型性强；酒度达10.5 %vol，Vc含量为0.94 g/L，残糖、总酸和挥发酸含量均较低；共鉴定出48种香气物质，占总峰面积的97.33 %，其中，酯类物质达19种，相对含量为34.65 %，高级醇(5种，15.38 %)和脂肪酸（6种，13.30 %）含量少，烷烃类和醛酮类等香气物质种类丰富，酒体协调、饱满，是1株适宜猕猴桃酒酿造的优良酵母。

objective to establish immunological methods specific for detecting antigens in different groups of monoclonal antibodies.methods indirect immnofluorescence assay was applied to identify specificity of the two groups of monoclonal antibodies prepared with crude antigen and recombinant antigen of aspergillus fumigatus,respectively.two different double monoclonal antibody sandwich elisa assays established with the two groups of antibodies were performed to detect antigents in the cell culture supermatants of 19 common species of aspergillus,penicillium marneffei,and 5 species of candidas.results the results of indirect immnofluorescence assay indicated that the monoclonal antibodies prepared with crude antigen of aspergillus fumigatus were specific for antigens in both clinical isolates and environmental isolates of aspergillus, whereas the other group of monoclonal antibodies was proved to be specific for aspergillus fumigatus of both clinical and environmental isolates.the elisa assay established with the crude antigen-specfic monoclonal antibodies could detect both of the clinical and environmental isolates of aspergllius, while the other assay could only detect aspergillus fumigatus of both clinical and environmental isolates.and no cross reaction with the cell culture of penialllium marneffei and candidas was observed with the two methods.conclusion the elisa assays can detect both of the clinical and environmental isolates of aspergillus,and differentiate aspergillus fumigatus from other species of aspergillus.

目的 用2组曲霉单克隆抗体建立特异性识别不同种类曲霉抗原的检测方法。方法采用天然烟曲霉抗原免疫，获得广谱针对曲霉抗原的单克隆抗体；采用重组烟曲霉抗原获得特异性针对烟曲霉抗原的单克隆抗体，用间接免疫荧光鉴定，并分别建立2种双抗体夹心elisa法，对19种常见的环境和临床分离曲霉株、马尔尼菲氏青霉菌及念珠菌培养液进行检测。结果间接免疫荧光显示，用天然烟曲霉抗原免疫获得的单克隆抗体(mabs-1)可广谱识别多种曲霉分离株，而重组烟曲霉抗原获得的单克降抗体(mabs-2)仅能特异性结合临床和环境分离的烟曲霉抗原。用mabs-1建立的双抗体夹心elisa法可检测19种常见曲霉株培养液；用特异性针对烟曲霉抗原单克降抗体(mabs-2)建立的双抗体夹心elisa法可特异性检测临床和环境分离株烟曲霉培养液；与其他曲霉株无交叉反应；2种双抗体夹心elisa法与马尔尼菲氏青霉菌及念珠菌培养液均无交叉反应。
