以马铃薯为辅料的黄酒生产工艺研究

研究了以马铃薯作为黄酒辅料的酿造工艺及条件,同时对发酵过程中的主要指标进行了监测。试验结果显示,添加与糯米同等量的新鲜马铃薯(按淀粉比,马铃薯占16%,糯米占84%),0.08%的黄酒活性干酵母、13%麦曲、糖化酶1.28 AGu/g(原料)、料水比为1∶0.7,在28℃进行96 h的前发酵,15℃下进行15~20 d的后发酵可以酿制马铃薯黄酒。发酵验证实验所得黄酒的各项理化指标均符合国家标准GB/T 13662-2000。     

Chinese nuclear energy politics: Viewpoint on energy

Since nuclear power is able to produce significant amounts of energy for a small amount of fuel, this method has recently attracted attention of most countries. In the present study, we seek to investigate the problems associated with nuclear energy in China. China is ranked 11th in terms of nuclear power generation, and it is currently producing 8587 MW of nuclear power with its 11 nuclear reactors. However, China supplies only 1.9% of its electricity from nuclear energy and it is much lower than the global average of 16%, because less than 1% of world’s uranium reserve exists in China. Currently, China is heavily dependent on imports from countries such as Russia and Australia to achieve primary fuels.

论中国近代大学校长在大学经营中的管理理念与实践智慧

中国近代大学校长诞生于中国封建制度走向崩溃,资产阶级革命兴起的社会大动荡时期。他们是近代知识份子,同时也是思想家、教育家．不仅受到中国传统儒家文化的熏陶,而且也受到西方自由主义文化的影响。他们关心民族的未来,忠诚于教育事业,为中国大学制度的创建,理念的形成做出了巨大的贡献。     

用中子活化分析法鉴别古陶瓷的种类

应用仪器中子活化法测定古耀洲瓷和古汝瓷的稀土元素（REE）和微量元素，结果显示两种瓷釉、瓷胎的稀土总量、稀土分配模式以及微量元素特征均有差异，甚至差异显著，这说明两种瓷釉、瓷胎的配料化学成分有区别，故REE和特征微量元素含量可作为陶瓷种类的鉴别标志。     

Fabrication and characterization of bone china using synthetic bone powder as raw materials

The synthetic bone powder was studied as a raw materials for bone china, completely replacing natural bone ash raw materials. The physical and thermal properties of samples obtained by the two bone powders were tested and comparatively studied. Performance tests included pyroplastic deformation, flexural strength, bulk density, sintering shrinkage, water absorption, transmittance, thermal expansion coefficient and the thermal shock resistance. The phase composition and morphology were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The results indicated that using synthetic bone powder could shorten the preparation time, reduce the sintering temperature and result in high-quality bone china. The pyroplastic deformation decreased from 9.14% to 7.92%, the three-point flexural strength increased from 123 MPa to 191 MPa, the light transmittance (at a 2-mm thickness) increased from 6.7% to 11.2%, the thermal expansion coefficient decreased from 8.24×10⁻⁶ °C⁻¹ to 7.69×10⁻⁶ °C⁻¹, and the thermal shock resistance increased from 140 °C to 180 °C. A continuous interface layer without cracks was produced by using the synthetic bone powder.
