It is concluded that the ultrafiltration preconcentration combining with multieffect evaporation is a promising concentration procedure for straw black liquor, which can not only reduce the concentration costs, but also improve the subsequent evaporation and combustion operation due to the desilicification and purification of ultrafiltration.

两种膜比较，磺化聚砜膜更易清洗，而且水通量大。5）超滤浓缩后，黑液中木素的浓度和纯度大大提高，超滤是从黑液中分离木素的理想方法。6）与多效蒸发相比，用超滤法浓缩麦草黑液可降低能耗70~85%，若用于黑液的预浓缩，再结合多效蒸发，不仅可以降低黑液的浓缩费用，而且由于除硅和纯化作用，会大大改善后继的蒸发和燃烧的操作。

We assumed that after the PACl〓 was dosed into water, its hydrolysis-aggregation-precipitation process combined the most popular"core-link"or hexameric ring scheme and the more recent model of polynuclear formation involving a typical specie of tridecameric,〓. The integrate pattern can nicely explained the phenomena.

另外，研究表明，PACl中预制的Alb形态和铝盐在混凝过程投加入水后形成的Alb形态在稳定性上有很大的区别，这无疑是由于它们的化学结构上的不同造成的，推测铝盐在投加入水后，其水解聚合过程按&六元环&模式〓和&核环&模式〓结合进行，这种综合模式可以很好的解释实验中的现象。

The reseach on activity changes of SOD, POD and CAT during the somatic embryogenesis of Y35 showed:(1) The activty of SOD was from 52.98 to 133.20 U·g-1·h-1, and remained a rising trend after early single embryo forming, this revealed that SOD might be positively correlated to the differentiation of embryogenic cell and the development of somatic embryo.(2) The activty of POD was from 0.05 to 0.50 U·mg-1·min-1, ascended firstly and desceded later, and was highest in embryogenic callus and lowest in late single embryo , this revealed that POD might be positively correlated to the division and differentiation of proembryo mass, while negatively correlated to the development of PEMⅢto late single embryo.(3) The activty of CAT was from 0.86 to 2.81 U·mg-1·min-1, showed an up-down-up trend, reaching to the highest peak at the time of early embryo formating and decreasing to the lowest at the time of early cotyledonary embryo formating, this revealed that CAT might be positively correlated to the development of early single embryo, while negatively correlated to the formation of middle single embryo and early cotyledonary embryo.The changes in activty of SOD, POD and CAT indicated these three antioxidant enzymes coregulated the differentiation and development of embryogenic cells during Larix somatic embryogenesis.4. Differentially expressed cDNA libraries of the stages of proembryo mass and somatic embryo maturation were successfully constructed by suppression subtractive hybridization.

The serum contents of IL-8, TNF-a, MDA ,lactic acid ,sICAM-land the myeloperoxidase in lung were remarkedly decreased in rats which were administrated by UTI. the D/W of lung and liver was decreased too. All of this demonstrate that Ulinastatin is beneficial in the severe thermal injury, which is helpful to the relief of MODS.

其结果显示在严重烧伤大鼠应用乌司他丁后，血浆中TNF-a、IL-8的含量、肺脏与肝脏的干湿重比、血清的乳酸与丙二醛含量以及sICAM-1含量，肺脏中的MPO含量，均明显降低，表明乌司他丁可能有助于减少或减轻对于严重烧伤后的SIRS/MODS的发生。

The results of Pancherz analysis shows that the correction of negative overjet is mainly due to the advancement of maxilla and upper incisors. But the position changes of mandible and lower incisors imply that severe maxillary hypoplasia with high angle and/or mandibular retrusion is contraindicated by the method conducted in this study.

头影测量侧位片Pancherz分析法的分析结果表明，本研究中上颌后缩患者反覆盖的矫治主要由上颌骨、上切牙的前移引起的，但下颌骨和下切牙位置的变化提示适应症的选择应注意避免上颌后缩同时伴有高下颌角和／或下颌后缩的患者。

The conventional cephalometric analysis chosen SNA, SNB, ANB, NA-PA etc to reflect the protrusion or retrusion of maxillary and Mandible, but they can't reflect this extent quantitatively. The Delaire cephalometric analysis can analyze the protrusion or retrusion of maxillary and Mandible quantitatively through Me-F1,Me-Met,Np-F1 etc. This method combine with conventional methods can evaluate accurately, quantitatively and directly.

传统头影测量分析选用SNA、SNB、ANB、NA-PA等角度来反映上下颌的前突或后缩，并不能定量的反映上下颌前突或后缩的程度；而Delaire头影测量分析中Me-F1，Me-Met，Np-F1可定量分析上下颌前突或后缩程度，结合传统的角度测量将利于直观、定量的评价，也利于准确的诊断设计。
