Four stocks of samples picked up in two different periods （summer and autumn） were analyzed. The standard chemical composition was determined on the whole plant and on its parts, the study was particularly focused on leaves and tops, not used in fibre production and available as livestock feed. Organic matter enzymic digestibility （OMD） was determined on all the samples by a double step method based on cellnlolytic andproteolytic enzymes. The chemical analysis showed good crude proteins content in leaves, tops and whole plant： 17.00 ~ 1.52%, 15.25 ~ 0.77% and 11.79 ~ 3.32% on dry matter （DM） basis respectively and good acid （ADF） and neutral （NDF） detergent fibre fractions. Lignin and ash resulted high in all plant parts and organic matter （OM） was consequently low, ash analysis showed high calcium concentration, especially in leaves, with values exceeding 4% of din, whereas the other micro （except the lead） and macroelements were in a normal range. OMD and energy values resulted poor in leaves, tops and in the whole plant and lower than the other forages commonly used as feed for runninants, thus the utilisation of ramie plant and its by-products requests further investigations.展开更多

In his famous lecture, he told us that the most powerful revolutionary force in the world today is science, science is essentially progressive, and the scientific culture is also a newer one. So Snow, after excluding scientific culture from the whole culture, calls the rest of the whole culture traditional culture. In his opinion, science is more important than humanities. All these ideas are faithfully reflected in his earlier literary work The Masters （1972b）. Snow＇s favor toward men of sciences in the novel is self-evident. ＂The Masters, therefore, may be considered as a political science novel rather than as a political novel＂. It was the Industrial Revolution which created our sensibility展开更多

The separation scheme consists of three steps： （1） the raw material is pre-separated by fractional distillation into four fractions according to normal boiling points; （2） appropriate extractants are selected to sep- arate the primary alcohols from the saturated alkanes in each fraction; （3） the extractants are recovered by azeotropic distillation and the primary alcohols in the extract phase are purified. Based on the proposed method, the total recovery rates of the primary alcohols and the saturated alkanes are 86.23% and 84.62% respectively. 2014 The Chemical Industry and Engineering Society of China, and Chemical Industry Press.
