潜江小城镇景观规划

潜江小城镇的水资源丰富但开发落后，绿系统不完善，街景缺乏工艺性。在对现状调查分析的基础上，提出了对过境公路、水体、街景进行动感空间、情感空间规划的建议，对乡土化设计、恢复性设计进行了探讨。     

稀土肥料对紫花苜蓿产草量影响的研究

通过7种稀土肥料处理对二年龄和三年龄苜蓿产草量的影响研究,结果表明不同稀土肥料对紫花苜蓿的增产效果差异显著,其中大丰收(氨基酸螯合稀土)、植物全营养素(巨源)、常乐益植素对苜蓿产量的提高效果最显著,稀土磷肥增产不明显。     

The study on site quality evaluation for dahurian larch (Larix gmelinii Rupr.)

Site quality of larch (Larix gmelinii Rupr.) in Da Xingan Mountain in Inner Mongolia was studied systematically with about 1000 temporary plots and computer software. The nature of site class and site index curve was discussed in view of general mathematical model of height growth. The height growth of dominant tree of four divisions of forest stands were studied and site index tables were constructed respectively. In order to unify the comparing standard and convenience for management in this region, site index table was constucted too. Based on discussing the action and accuracy of forest type, a series of site quality evaluation (forest type-site index class-site index) was suggested. This subject of study is supported by the National Natural Scientific Fund (No. 39270549).     

植物活体水分探测仪的研制及测试初报

利用NIM插件探测器及金硅面垒探头组装了植物活体水分探测仪;筛选并分析了仪器的最佳工作条件;检测了春小麦、玉米、苜蓿、豌豆、红豆草叶片鲜重的变化。结果表明;叶片水分随时间损失大的,其抗旱性差。叶片保水的秩序为:红豆草、豌豆>苜蓿>春小麦>玉米。     

长期投资组合的连续时间模型

对Black—Scholes型市场中的投资问题建立了两个连续时间模型——“均值一在险资本”模型和“均值一在险效用”模型，求出了模型的显式解；综合比较这两个模型及“均值一方差”模型，得出：“均值一在险资本”模型更适合于长期投资组合分析，它与实际观察结果是一致的，即投资的计划期越长，投资者持有的风险资产比例会越大．     

山楂缺铁黄叶病及应用硝黄铁防治研究

根据调查初步总结出山楂缺铁黄叶病的发生发展规律、致病因素及其对山楂生产的危害。用新研制的高效价廉、储运方便的硝黄铁矫治,效果明显。黄化病株复绿率40%～87%,三级病株减少36%～100%,叶绿素含量提高64%～224%,喷肥区比对照区株产提高25%。同时增加了果实中糖、酸、果胶及钙、铁含量,提高了果实品质。     

The Location Algorithm of QRS Waves Based on Fractal Box Dimensions Detection Methods

We research fractal characteristics of ECG signal, and find that it is logarithmic linear relationship between the boxes number covering signal and box scale. It is shown that ECG signal have some characteristics. Further more, we discover that fractal dimensions at QRS site are higher than others when using a time windows to detect signal. Based on this foundation, we raise a location algorithm of QRS waves which is based on fractal boxes dimension detection methods. The application results of this algorithm show that it can get rid of noise in ECG effectively with high speed, so this algorithm can be used in real time detection of ECG signal.
