牡荆油自乳化释药系统的制备

通过溶解度试验、处方试剂筛选和相图绘制,以形成乳剂的乳化程度和乳滴粒径大小为指标,对牡荆油处方中的表面活性剂、助表面活性剂进行筛选,寻找牡荆油自乳化制剂的最佳处方配比。试验结果表明,以牡荆油为油相,Tween-80或EL-40为乳化剂,以无水乙醇为助乳化剂均能形成较好的自乳化体系,最佳处方为牡荆油Tween-80乙醇=432。     

茭白配方专用肥肥效比较试验

通过与常规施肥比较,研究茭白配方专用肥对茭白生物学性状、产量和品质的影响。试验结果表明:茭白商品性有明显改善,粗脂肪、维生素C、总糖、氨基酸等品质指标增幅达到极显著水平,并可实现增产增效21.96%,节约肥料成本6.53%,利润提高25.98%。在配方专用肥的基础上增施氮肥,不能提高茭白产量,且肥料成本增加,种植效益明显下降。     

Determination of growth-stage-specific crop coefficients (Kc) of cotton and wheat

Development of crop coefficient (Kc), the ratio of crop evapotranspiration (ETc) to reference evapotranspiration (ETo), can enhance ETc estimates in relation to specific crop phenological development. This research was conducted to determine growth-stage-specific Kc and crop water use for cotton (Gossypium hirsutum) and wheat (Triticum aestivum) at the Texas AgriLife Research field at Uvalde, TX, USA from 2005 to 2008. Weighing lysimeters were used to measure crop water use and local weather data were used to determine the reference evapotranspiration (ETo). Seven lysimeters, weighing about 14 Mg, consisted of undisturbed 1.5 m × 2.0 m × 2.2 m deep soil monoliths. Six lysimeters were located in the center of a 1-ha field beneath a linear-move sprinkler system equipped with low energy precision application (LEPA) and a seventh lysimeter was established to measure reference grass ETo. Crop water requirements, Kc determination, and comparison to existing FAO Kc values were determined over a 2-year period on cotton and a 3-year period on wheat. Seasonal total amounts of crop water use ranged from 689 to 830 mm for cotton and from 483 to 505 mm for wheat. The Kc values determined over the growing seasons varied from 0.2 to 1.5 for cotton and 0.1 to 1.7 for wheat. Some of the values corresponded and some did not correspond to those from FAO-56 and from the Texas High Plains and elsewhere in other states. We assume that the development of regionally based and growth-stage-specific Kc helps in irrigation management and provides precise water applications for this region.     

非瞬时或突变的马尔可夫链的一种应用方法

介绍对于一种非瞬时或突变的状态转移过程.采用Bayes方法修订马尔可夫过程的状态转移概率矩阵;将先验概率分布修订为后验概率分布;对整个过程的信息加以吸收,得出能够反映整个过程的状态转移概率矩阵,从而达到预测目的.由此还得出一个重要结论:吸收信息的无序性.     

参考蒸发蒸腾仪的研制及其应用研

根据植物的蒸腾机理与土壤的蒸发机制，利用生物膜技术，研制了参考蒸发蒸腾仪。该仪器可很好地模拟土壤蒸发与植物蒸腾的自然物理过程。从理论上对仪器直接测定法与Penman-Monteith法、蒸发皿法进行了对比分析。在应用试验上，利用蒸渗仪值对三种方法进行了校核，结果表明：仪器直接测定法的精度稍差于Penman-Monteith法，但较蒸发皿法有很大提高。仪器使用方便、维护简单、价格低廉，易为我国普遍存在的经济与文化水平不高的农民用户所接受，将有良好的商品化开发及广阔的市场应用前景。     

Equine chronic diarrhea: Traditional Chinese veterinary medicine review

Chronic diarrhea is a common problem in equine practice. Herbal medicine has been used for the treatment of gastrointestinal disease in horses for at least one thousand years. In present-day equine practice in China, the most common approach to treat chronic diarrhea is herbal medicine, or a combination of herbal medicine and acupuncture. Three types of chronic diarrhea in horses will be described in detail in term of symptoms, diagnosis and herbal treatments in this paper. Nineteen herbal formulas for treatment of different types of diarrhea will be introduced. Clinical results of each herbal formula will be evaluated. Acupuncture treatment of this problem will also be included.     

黄瓜茉莉花茶保健饮料的研制
