替代PVA的接枝变性淀粉浆料的研究

通过实验研究，开发出了替代PVA的接枝变性淀粉浆料，产品中残留的单体极少，接枝率将近13％，其粘度低，粘度热稳定性好，对涤／棉纤维的粘附性好，上浆性能和目标浆料70％PVA＋30％氧化淀粉相比，浆纱强力和伸长率、毛羽均好于目标浆料，耐磨性能和目标浆料也相差无几，克服了其他接枝变性淀粉浆料浆纱耐磨性差的缺点，在实验室涤／棉混纺经纱上浆中全部替代了PVA，取得了很好的上浆效果。

基于GIS技术的阆中市土地分级

将GIS技术引入阆中市土地分级研究中，应用其空间数据采集、处理和分析等功能，同时考虑坡度、速效磷、速效钾、有机质等肥力因素，对该地区的土地分级．研究结果表明阆中市土地以Ⅰ与Ⅱ级面积占比重较大，其中Ⅰ级72152hm^2，占38．6％，Ⅱ级65231hm^2，占34．9％，并且主要分布在阆中市中部与南部．     

论医疗损害违法行为与损害后果之间的因果关系

由于医疗过程的复杂性与人类认识能力的局限性,在认定医疗损害的违法行为与损害后果之间的因果关系时更会遇到很多的困难.笔者认为,在探究治疗行为与损害结果因果关系的过程中,应按照二分法的一般规则,在步骤上,分二步走.首先,考察事实因果关系,其次,考察法律因果关系.特殊情况下运用相当因果关系及盖然性加以认定.其中,占据最重要地位的是盖然性因果关系理论.     

Co-adaptation between modern oasis urbanization and water resources exploitation: A case of Urumqi

Water resources exploitation is always very important during the whole oasis urbanization in arid zone, adapting with urban development in between contradiction and coordination. Taking Urumqi City as a case, co-adaptation of water exploitation and urban growth is imitated by interactions between water supply and oasis city’s expands on population, economy and environment. In different urbanization stages, the co-adaptation can be represented differently, which can be summarized by five phases: elementary coordination, expanding coordination, expanding contradiction, adapting contradiction, and adapting coordination. Cost of water consumption, proportion of water use and efficiency are the main influence factors to help the co-adaptation.

     

多热源碳化硅合成炉热源参数与产率的关系研究

利用ANSYS软件对多热源炉温度场数值计算的模拟结果,系统地分析了热源数目、炉芯间距与产率之间的关系.研究发现,炉芯间距过大或过小,产率均有一定程度的下降。对于10 000 kVA的变电系统和炉长L×炉宽B×炉高H=20 m×5 m×5 m的炉子而言,热源数目为4,对应的炉芯尺寸为H=B=0.34 m,炉芯间距d=1.0 m时,产率最高。这一结果通过工业生产得到了验证。     

A new way of transformation from a-quartz to coesite

A laboratory method combining the high-energy mechanical ball milling and high static pressure has been suggested for modelling synthesis of coesite in the Earth's crust. A window of milling time, a mechanical collision-induced intermediate phase ofα-quartz and its condition of easily crystallizing into coesite under the condition of 3.0 GPa, 923 K, < 1.0 min have been discovered. The new method needs much shorter synthesizing time and lower synthesizing critical pressure than those used before. The Raman spectra for the coesite synthesized by the present method have covered all the information of those natural and synthesized coesites reported before. It is demonstrated that this method has a great potential in geo-science research and implied the other possible mechanism of coesite formation in the Earth's crust.
