曾国藩倡行船山学,对近代中国产生了深远的影响,从此之后,船山学便走出湘学地域,成为近代中国的一种“显学”。曾国藩力倡船山学,是出于“保卫中国传统文化”和树立湘军思想旗帜这样双重目的。 相似文献

We employed direct-current electric fields (dcEFs) to modulate the chemotaxis of lung cancer cells in a microfluidic cell culture device that incorporates both stable concentration gradients and dcEFs. We found that the chemotaxis induced by a 0.5 μM/mm concentration gradient of epidermal growth factor can be nearly compensated by a 360 mV/mm dcEF. When the effect of chemical stimulation was balanced by the electrical drive, the cells migrated randomly, and the path lengths were largely reduced. We also demonstrated electrically modulated chemotaxis of two types of lung cancer cells with opposite directions of electrotaxis in this device. 相似文献

This study reports on the process of developing a test to assess students’ reading comprehension of scientific materials and on the statistical results of the verification study. A combination of classic test theory and item response theory approaches was used to analyze the assessment data from a verification study. Data analysis indicates the test has satisfactory validity and reliability. The Reading Comprehension of Science Test (RCST) components have a wide range of difficulty, which suggests that the RCST is appropriate for a relatively large percentage of students. Based on the accepted relationships among science, language, and literacy, integrated literacy–science instructions are highly recommended. 相似文献
