By using Caterpillar-SSA analysis method, through the process of embedding, singular value decompo-sition, grouping and diagonal averaging, the seasonal pre-cipitation trend at north Helan Mountain and Baiyinaobo regions, inner Mongolia for the next 20 years is forecasted. The results show an increasing precipitation trend from 1992 to 2004. in the subsequent decade the precipitation should reduce quickly, and it will reach a minimum near 2012 to 2014 in both regions. The drought caused by the decrease of the precipitation from May to July in the north Helan Mountain area during the period of 2013—2014 is probably quite similar to that around 1929. Further, the period of pre-cipitation gradual increase follows in the researched regions.

提出一种同步时标可自由设定的新型广域电网相量测量装置(PMu),它由频率自适应等间隔采样模块、同步时标形成模块和核心微处理器模块等构成。通过硬件电路与计算软件的合理分工与协调配合,实现了相量同步测量装置中"时间同步"与"频率同步"的解耦处理,从而装置能够根据自由设定的同步时标与时标同步方式,自动定位截取整周期采样数据(无频谱泄漏)进行高精度离散傅里叶变换(DFT)相量计算,并通过简单的方法对截取DFT数据窗时造成的时标同步偏移量进而计算相量的相角偏差量进行高精度线性修正。同时对同步时标位于DFT数据窗首、中、末点3种情况下的相量测量精度进行了仿真研究,得出了"中点同步"精度最高的正确结论。

双相不锈钢(DSS)的铁素体-奥氏体微观结构将良好的机械性能及抗腐蚀性能结合于一体,并且价格也非常具有竞争力。DSS的一个典型性质是其较高的抗点蚀性,这一特性使DSS适用于苛刻环境下的结构应用。然而,DSS的应用受限于危险金属相结构的易感性,从而对其冲击韧性和耐腐蚀性产生不利影响。此析出现象引起了人们的极大关注,并且不同析出次序(σ相,χ相和碳化物)也已被相继提出。本文综述了有关二次相形成的研究,并对最常用分析方法进行比较。对这些析出在连续冷却和等温处理(以定义时间和次序)条件下进行了考察。

The hematological and serum biochemical profiles of apparently healthy exotic breed of dogs in Jos, Plateau state, Nigeria was studied in this research. One hundred and seven exotic breed of dogs were examined from October - December, 2018. The results from physical, clinical examinations and parasitological examinations were used to determine apparently healthy exotic breed of dogs which were used in this study. The parameters measured were rectal temperature, parasitaemia, hematology which included red blood cells count, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin and hemoglobin content;total white blood cell count, including eosinophils, neutrophils, lymphocytes, monocytes, granulocytes counts, and platelets;serum biochemical parameters also included Aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total proteins, albumin, globulin, blood urea nitrogen, creatinine, cholesterol and triglyceride, using standard methods. Data generated from the study were statistically analyzed using students t-test one-way analysis of variance while the level of significance was ily:"">measured at p is study, hematological and serum biochemical values were comparable to and not different from those reported for dogs in available literature, but the upper and lower reference limits (minimum and maximum values) were different for most parameters.
