The content of calcium, magnesium, zinc and iron in LBP-4a were 127. 9070mg·g〓, 32. 3953mg·g〓, 0.3845mg·g〓 and 0.2930mg·g〓, respectively. The content of galacturnic acid in LBP-4a was 55. 45% while the content of protein is 3. 80%. According to IR spectra, it contains -COOH group,-NH- roup,-OH group,-NH〓 group and β-D-glucose. The backbone of sugar residues chain in LBP-4a were contained 1→6 indican bond according to periodate oxidation and the results of β-elimination reaction indicated that the chain of polysaccharides and protein were connected by O-linked chemical bond. The photograph of LBP-4a got by laser scanning confocal microscope and scanning electron microscope showed that the LBP-4a combined both with each other and with itself in its crystalloid. The crystalloid was flake and anisotropic.

由LBP-4a的红外光谱图知：LBP-4a中含有-COOH、-OH和-NH〓或-NH-基团，糖链中含有β-D-吡喃葡萄糖；高碘酸氧化实验知LBP-4a糖链中不具有连二羟基和连三羟基结构的单糖残基：具有连二羟基结构的单糖残基：具有连三羟基结构的单糖残基=57.0：16.2：1，六碳糖残基的连接中含有1→6连接的糖苷键；通过β消去反应证明LBP-4a中多糖链和氨基酸间为-O-型连接；由激光扫描共聚焦显微镜和扫描电镜对LBP-4a结晶观察结果推测：LBP-4a结晶中同时存在分子间和分子内结合的现象，LBP-4a分子相互结合时，并不是无规则的相互缠绕形成无规线团结构，而是形成片层结构，并且LBP-4a结晶可能具有各向异性的性质。

The adsorption isotherm of neptunium on silica gel correspond to the form of Langmuir isotherm. According to Clausius-Claperon equation,from the slope in InKd vs 1/T plot,adsorption heat could be estimated. From the data of adsorption heat it is concluded that the adsorption of neptunium on silica gel in nitric acid solutions belongs to chemical adsorption and the adsorption process is an endothermic reaction.

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。
