Maleic Anhydride is important organic raw material and the third biggest acid anhydride next to benzene anhydride and acid anhydride. In recent years, Maleic Anhydride is esterified and hydrogenised under pressure to make 1,4- butanediol butylene glycol, and it is also hydrogenised to tetrahydrofuran, which enables Maleic Anhydride to become the raw material for producing high-value-added products and to be more widely applied.

顺酐是重要的基本有机原料，也是世界上仅次于酸酐和苯酐的第三大酸酐，近年来，顺酐脂化低压加氢制1.4-丁二醇和顺酐加氢制四氢呋喃技术的开发成功，是顺酐成为生产高附加值产品的原料，应用领域有了更进一步的拓展。

The fiber length has only little influence on the basic density within the growth rings, and significant correlation at 0.01 levels was found between the basic density and the fiber length among the different rings. Only slight negative correlation was found between the basic density and the fiber width within the growth rings, but significant positive correlation at 0.01 levels was indicated between the basic density and the fiber width among the growth rings, contrary to that of fiber length. It was demonstrated that significant positive correlations at 0.01 levels between the basic density and fiber double wall thickness, fiber length to width ratio and double wall thickness to diameter ratio, significant negative correlations at 0.01 levels between the basic density and fiber diameter and diameter to width ratio, only slight negative correlation between the basic density and fiber width both in the same growth rings and among the different growth rings. No significant correlation was found between the basic density and the vessel morphological features, nor was the tissue proportion in the same growth rings. But among the different rings, it was found there was significant positive correlation at 0.01 levels between the basic density and the fiber proportion among the different rings, and significant negative correlation at 0.01 levels between the basic density and vessel-elements proportion and ray proportion, only slight negative correlation between the basic density and the parenchym proportion. Significant or no significant negative correlation was found between the basic density and the microfibril angle in the same growth rings, but significant negative correlation was found between the basic density and the microfibril angle among the different growth rings.

生长轮内纤维长度对基本密度的影响不大，而在不同生长轮间纤维长度与基本密度达极显著正相关，纤维宽度与此相反，同一生长轮内纤维宽度与基本密度极显著负相关，不同生长轮间只有微弱负相关；基本密度与纤维双壁厚、长宽比、壁腔比在生长轮内和生长轮间均呈极显著正相关，而与胞腔直径、腔径比均呈极显著负相关，仅与纤维宽度呈微弱的负相关；导管形态对基本密度的影响不显著；同一生长轮内组织比量对基本密度的影响也不显著，但不同生长轮间基本密度与纤维比量呈极显著正相关，与导管比量和木射线比量呈极显著负相关，与轴向薄壁细胞比量仅呈不显著负相关；生长轮内基本密度与微纤丝角呈显著或不显著负相关，但在生长轮间这种负相关达到极显著水平。

In 1999, the national production capability of maleic anhydride is 166000 ton and the actual production is more than 100000 ton, With the rapid development of national economy, the down-stream products of maleic anhydride are being used in more and more fields and the market demand of maleic anhydride is increasing day by day.

随着国民经济的快速发展，顺酐下游加工产品的应用领域不断扩大，市场对顺酐原料的需求量也昌逐增长。
