Recent results indicate that （1） Oryzeae is monophyletic and falls into two main clades corresponding to the traditionally recognized subtribes;（2） Close affinities of the monoecious genera are not supported, suggesting the multiple origins of unisexual florets;（3） Previous recognition of three monotypic genera （Hydrochloa, Porteresia and Prosphytochloa） is not justified;（4） Based on dating using molecular clock approach, it is estimated that Oryza and Leersia branched off from the remaining genera of Oryzeae -20 million years ago, and separated from each other -14 MYA.

目前已有的研究结果表明：稻族是单系类群，可分为两个主要分支，相当于传统的两个亚族（Zizaniinae和Oryzinae），但稻族单性花小穗是多次起源的，不宜作为划分亚族的依据；一些单型属（Hydrochloa、Porteresia和Prosphytochloa）的建立得不到分子证据的支持；根据分子钟原理估计稻族两个主要分支的分歧时间在大约2000万年前，而稻属和近缘属假稻属Leersia的分歧时间为1400万年：稻属内主要类群的分歧时间在900万年前左右。

Results Poor social economic status was prevalent in the longevous elderly population. The elderly people had limited social contacts except from their families. The daily lives of 65.0% of the longevous elderly were taken care of by their families. More than 81.8% of the longevous elderly people were financially supported by their families. About 89.2% of the longevous elderly people had accessed to spiritual supports in difficult circumstances, among 88.7% came from families.

结果 被访老人社会经济地位普遍低下；其社会网络主要是家庭，社会接触单一，但是能够从中得到较高的社会支持：65.0%老人日常生活主要由子女照顾，81.8%主要经济来源于家庭，在遇到困难时89.2%的老人曾经得到过安慰和关心，多数情况下(88.7%)是源自子女的关怀。

The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite. The manganocolumbite, manganotantalite, wodginite and titanowodginite are the main niobium and tantalum minerals.

Mineral fuel is the primary energy source in the world today, thereinto coal resource holds in store more than 75 percent in the total energy source. During coal's utilized, nocuousness matter expels into environment through all kings of method and works serious environmental pollution. Desulphurization has become one of primary objects of cleaning coal. At present, there are some primary problems of removing sulfur from coal. It is the size of coal is too small, the time of removing sulfur is too long, the technology is too complicated and the investment is much expensive etal.
