Through quantitative calculation, the conclusions are drawn: 1it was obvious that the south was faster than the north; contrast of economic level has reversed since reform and opening.2The reasons accountable for these changes consist of politics, export strength,economic system,input intensity (special foreign direct investment), industrial structure and so on.3Social-cultural elements have certain influence by all means.4To turn the north tardy, we should quicken the pace of reform and opening in the north, make efforts in restructuring big and middle state-owned enterprises, vigorously carry out the strategy of making the country strong through science and education.5The north must grasp opportunity, build new economic growth pole, retransfer and upgrade industrial structure as soon as possible.

通过定量计算得出结论：经济发展速度南快北慢现象是明显的，经济发展水平改革开放前北高南低，目前则是南高北低，致使中国经济发展出现了新的不平衡。南快北慢的原因是：地缘优势和超前观念所获得的政策倾斜，导致了出口能力和投资强度的差别；工业结构(特别是所有制结构和轻重工业结构)的作用也很明显，而国家投资的作用很小，且越来越不重要。扭转北慢的对策是加大北方改革开放力度，切实搞好国有大中型企业改造，大力实施科教兴国战略；北方要注意把握机遇，构筑新一轮经济增长点，尽快实现产业结构的升级和转型。

To produce the scientific evidence for developing and manufacturing new antitumor drugs.Methods: 1 The inhibitory effect on cell growth of Hela was measured by MTT assay in treated or untreated groups (3.125, 6.25, 12.5, 25, 50μg/ml TAM and control) for three different treatment times (24h, 48h and 72h).2 Apoptosis and cell cycle were measured by FCM in four experimental groups (0, 4, 16, 40μg/ml TAM) for 48h.3 Adopting Wright and Giemse's staining to observe the morphology of Hela cells which treated with 40μg/ml TAM.4 Using invasion experiment to detect the Hela cells'invasive abilities which treated with 40μg/ml TAM.5 The protein expressional levels of P-ERK, ERK, C-myc and Cyclin D1 in Hela cells untreated or treated with 4, 16, 40μg/ml TAM for 24h were measured by Western blot.6 Expression of anti-apoptotic gene bcl-2, apoptotic gene bax and MMP-9 in Hela cells of four experimental groups (0, 4, 16, 40μg/ml TAM for 24h), were observed by revers transcription PCR.7 The protein expression of P-ERK, ERK, Bcl-2 and Bax in Hela cells treated with 40μg/ml TAM for 24h observed by laser scanning microscopes.
