The conditions of low analysis phosphorous fertilizer's manufacture, use and resources utilization were studied base on the inquisitional and statistical data. It shows that the inconsistency between the steady outputs of low analysis phosphorous fertilizer and the rapid demand of all kinds of nutrient for agricultural production can increase the market room of low analysis phosphorous fertilizer. It also indicates that the inconsistency between the phosphate demand of low analysis phosphorous fertilizer and the usability of phosphate rock can bring great development in future.

基于农户调查和统计数据，对我国低浓度磷肥的生产分布状况、使用状况、资源利用状况的分析表明，低浓度磷肥产量的徘徊不前与农业生产对中量元素需求增加的矛盾将拓展低浓度磷肥的市场空间；生产低浓度磷肥适用的磷矿品位与我国磷矿资源条件的吻合，使低浓度磷肥在未来有很大的发展空间。

Although the data from the 1920s and 1930s show a highly unequal distribution of land, Brandt and Sands show that shifting the statistical base from landholding per household into per capita terms narrows the gap between poor and wealthy households.

尽管20世纪二十年代到三十年代的数据显示了较高土地分配的不公，白若文和桑德斯表明，从每户所有土地到人均土地的统计变化缩小了贫困家庭和富裕家庭的鸿沟。

The nonlinearity and discrete gradient inherited in CAViaR model is a conundrum for parameter estimation. We take the asymmetric Laplace distribution with scale parameter as the error process; indicate the variance has a minimum positive value when the scale parameter is a constant, conflicting with the distribution of real financial data. Further we estimate the parameters of indirect TARCH-CAViaR model base on Bayesian framework and Markov chain Monte Carlo method. The optimal scale parameter can also be obtained by Markov chain Monte Carlo method.

CAViaR一般模型中递归分位回归方程的非线性和非连续可微性是参数估计的一个难题，基于含有尺度参数的不对称拉普拉斯分布作为误差过程，指出将尺度参数固定为常数会导致不对称拉普拉斯分布随机变量的方差存在最小正值的限制，与实际金融数据分布不符；进而提出采用贝叶斯分析和马尔科夫链蒙特卡罗模拟方法，估计间接TARCH-CAViaR模型的参数，并可获得尺度参数的合理估计。
