土壤调节剂“盐碱车”的推广应用

通过对土壤施入“盐碱丰”改良盐碱化严重的耕地，改良土壤的结构和理化性状，改善土壤的分散力，增加钙、镁离子的溶解度，置换出钠离子，经灌溉溶解作物周围盐分，达到改良土壤促进作物生长的效果。     

斜拉桥抖振分析中计入背景分量的实用方法

在大跨桥梁的拌振分析中，通常采用的是Ｓｃａｎｌａｎ颤拌振分析方法，这一方法只考虑了共振响应、而忽略了背景响应，最近的研究表明背景分量在某些情况下可能占有较大比重，因此考虑背景响应具有一定的必要性，在对背景分量进行详细分析和大量计算的基础上，拟合出包括各种影响参数的适合于斜拉桥竖向抖振背景响应修正的计算公式，可以在斜拉桥竖向抖振计算中方便地计入背景响应。

一种有效的运动目标辨别方法

提出了一种利用图像序列中两帧相邻图像从分割所得二值图像的合个候选目标块中确定真实目标的有效算法，背景配准后，可获得背景噪声分布直方图，同时获得具有对应关系的候选目标块间的噪声分布直方图，通过比较它们与背景噪声分布直方图之间的差异性，即可准确地辨别出真实目标。通过对实际图像序列进行实验，证实了本方法的有效性。     

肖邦夜曲的永恒性

肖邦创造了永恒的夜曲。当肖邦所创作的音符由钢琴中流泻出来,他究竟属于“浪漫乐派”或是“国民乐派”的争辩已毫无意义。因为他是波兰的肖邦,也是世界的肖邦;他是浪漫时代的肖邦,也是我们心中永恒的肖邦。     

Some evidence of drying trend over northern China from 1951 to 2004

The surface wetness index, Palmer drought sererity index and the retrieval of soil moisture over China were calculated using monthly precipitation and monthly mean surface air temperature. Based on the contrast analysis of the variation of the above three indices and precipitation, the dry/wet spatio-temporal pattern of northern China in the last 54 years was revealed, and the evidence of drying trend over northern China was analyzed, especially. The results show the following four facts: (1) The drying trend is the main characteristic of the eastern part of Northwest China and the central part of North China since the 1980s and it was enhanced in the last 15 years mainly due to the precipitation decrease and the temperature increase; (2) During the last 54 years, there was only one dry/wet shift at the interdecadal scale occurring in the eastern part of Northwest China and the central part of North China in the late 1970s, which was related to 1977/1978 global abrupt change, whereas there were three shifts in Northeast China, one was in the mid 1990s and the other two were in 1965 and 1983, respectively; (3) Unlike the variation trend of other subregions of northern China, the western part of Northwest China is currently located in a relatively wetting period, which is weak-ened due to the temperature increase; (4) The extreme drought frequency is obviously increasing in the eastern part of Northwest China, the central part of North China and Northeast China since the 1980s, which is closely related to the precipitation decrease and temperature increase in these subregions.
