In this paper, adopted augmenting culture in nitrite bacteria culture media and the method of silica gel plate isolation,31 strains of bacteria were isolated from vegetable garden soil of our school. The color reaction test was carried out with Griess reagent and culture fluid, which was regarded as the index to determine producing NO2- or not. 13 strains which color were deep were obtained and they were further rescreened by doing nitrite test. A strain N4(coded N4,the same to the following)with higher rate of nitrosification was picked up after rescreened; A strain B08( coded B08 ,the same to the following) with higher rate of denitrification was obtained after isolated and rejuvenated from our lab conserving mixed denitrifying bacteria culture.

本研究采用亚硝化细菌富集培养基选择培养和硅胶平板分离法，从本校农场菜园土中分离到31株细菌，以格利斯试剂对培养液的反应颜色深浅作为指标衡量其产NO_2~-的多少，经初筛从分离株中筛选出13株格利斯试剂反应颜色较深的菌株，再对这13株菌作亚硝化试验，最终选出一株亚硝化速率较高的菌株(编号为N_4，下同)；另外，通过对本实验室保存的反硝化细菌混合菌液进行分离复壮，筛选出一株反硝化速率高的菌株编号为B_

Isolation and identification results of volatile compounds showed that aldehydes, alcohols and ketones were the major volatile compounds formed in the processing of XUANWEI ham, and had the highest relative contents in the 6-month-old, which were 11326.18, 947.29 and 554.95 μg nonane 100g-1, respectively. The result was relevant to intense hydrolysis of intramuscular fat in the pre-processed ham (4-month-old).

挥发性化合物的分离鉴定结果表明：醛、醇和酮类是火腿加工过程中形成的主要挥发性化合物，在6月龄时，它们的相对含量最高，分别为11326.18、947.29和554.95μg壬烷／100 g，此结果与加工前期（4月龄）肌内脂肪发生强烈水解相关。

This may be due to the geographic isolation and the borers nonmigratory character.

In this method,fault detection is based on functional test for circuit boards, and fault isolation is based on the com- parison of actual response and expected response on correlative nodes,Besides, the aproach of building diag- nostic database and hardware composition of test system is introduced,According to this method,a practical test system has been made successfully.it can isolate 80% faults to nodes.

在该方法中，故障检测是基于对电路板的功能测试，故障隔离是基于相关节点的实际响应和预期响应的比较，此外还介绍了诊断数据库的建立方法以及测试系统的硬件组成。根据这一方法已研制成功一个实用测试系统，它能把80％故障隔离到节点。
