浸润型肺结核与慢性纤维空洞型肺结核分型的依据是（）

A.结核中毒症状

B.血沉

C.痰菌检查

D.肺实变体征

E.胸部X线片改变

答案

参考答案：E

解析：浸润型肺结核与慢性纤维空洞型肺结核是肺结核演变过程的两个时期，均具有结核病的常见临床症状及试验室检查。分型的最主要鉴别是胸部X线改变特点。浸润型肺结核X线显示病灶多在锁骨上下，为片状、云絮状，边缘模糊阴影及干酪样病灶、空洞等。慢性纤维空洞型肺结核X线显示一侧或两侧单个或多个厚壁空洞，肺门被牵拉向上，肺门呈垂柳状阴影，纵隔牵向病侧。临近或对侧肺组织常有代偿性肺气肿。

     The following card includes a brief summary and a short assessment of a research paper. It can
provide a guide for further reading on the topic.
     Trevor, C. O., Lansford, B. and Black, J. W., 2004, "Employee turnover (人事变更) and job
performance: monitoring the influences of salary growth and promotion", Journal of Armchair
Psychology, vol. 113, no.1, pp. 56-64.
     In this article Trevor et al. review the influences of pay and job opportunities in respect of job
performance, turnover rates and employees' job attitude. The authors use data gained through
organizational surveys of blue-chip companies in Vancouver, Canada to try to identify the main
cause of employee turnover and whether it is linked to salary growth. Their research focuses on
assessing a range of pay structures such as pay for performance and organizational reward plans.
The article is useful as Trevor et al. suggest that there are numerous reasons for employee turnover
and a variety of differences in employees' job attitude and performance. The main limitation of the
article is that the survey sample was restricted to mid-level management, thus the authors indicate
that further, more extensive research needs to be undertaken to develop a more in-depth
understanding of employee turnover and job performance. As this article was published in a
professional journal, the findings can be considered reliable. It will be useful additional information
for the research on pay structures.
1. The research paper published is primarily concerned with _____.
[ ]
A. the way of preventing employee turnover

[ ]
A. the data analysis is hardly reliable

D. the research method is out-of-date
3. Who might be most interested in this piece of information?
