Standard test method for monotonic tensile behavior of continuous fiber - reinforced advanced ceramics with solid rectangular cross - section test specimens at ambient temperature 室溫下用實心矩形截面試樣進行連續(xù)纖維增強高級陶瓷恒定抗拉性能的標準試驗方法
Standard test method for monotonic tensile strength testing of continuous fiber - reinforced advanced ceramics with solid rectangular cross - section test specimens at elevated temperatures 高溫下帶實心矩形截面試樣的連續(xù)纖維增強高級陶瓷的單值抗拉強度試驗的標準試驗方法
Standard test method for monotonic compressive strength testing of continuous fiber - reinforced advanced ceramics with solid rectangular cross - section test specimens at ambient temperatures 室溫下帶實心矩形截面試樣的連續(xù)纖維增強高級陶瓷的單值抗壓強度試驗的標準試驗方法
By using serial correlation test and cross - section test through the data of the share companies that were listed in shanghai stock exchange before 16th oct 1998 , the size effects in china stock market was tested in the period from 16th oct 1998 to 26th oct 2001 . all the share companies which in total 373 were grouped into 11 according to four different criterions . these four different criterions were total circulating captal stocks , total circulating market value , total capital stocks , total value of a share company . through the correlation test between the abnormal return rate and the size of the group , no size effect was found through the size criterion of the total value and the total circulating value except only one period 運用序列相關性我國股票市場的小公司效應進行實證檢驗,所采用的樣本是在1998年10月16日以前掛牌上市的373家上市公司從1998年10月16日到2001年10月26日,共150周的交易數據。對公司進行以規(guī)模大小分組時,分別采用了流通市值、流通股本、總市值和總股本四種不同的標準進行投資超額收益率規(guī)模相關性分析,發(fā)現(xiàn)以總市值和流通市值為規(guī)模標準的實證結果除個別時期內存在著小公司效應外,其它時期并不存在小公司效應,而以總股本和流通股本為標準的小公司效應最為明顯;另外,小公司效應在統(tǒng)計區(qū)間內表現(xiàn)出時段性。
