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.

对Y35体细胞胚胎发生过程中抗氧化酶活性变化的研究显示：(1)SOD活性在52.98~133.20 U·g-1·h-1之间，并在早期单胚形成后一直保持上升的趋势，表明其与胚性细胞的分化及体细胞胚的发育均具呈正相关；(2)POD活性在0.05~0.50 U·mg-1·min-1之间，呈现出先下降后升高的趋势，在胚性愈伤组织中最高，而在后期单胚形成时降至最低，表明其与原胚团的分裂和分化呈正相关，但与PEMⅢ向后期单胚的发育呈负相关；(3)CAT活性在0.86~2.81 U·mg-1·min-1之间，表现出升-降-升的变化趋势，在早期单胚形成时升至最高，在早期子叶胚形成时降至最低，表明其与早期单胚的发育呈正相关，而与中期单胚和早期子叶胚的发育呈负相关。

Chinese ancient feminine literature had two characteristics: firstly,writers changed from the former noble women,official s wives to the later literary family whose works made a feature of exquisite style;secondly, content s changed from feminine querimony to a kind of ideality of showing feminism and perusing personality release during the Ming and Qing Dynasty,which had progressive significance.

初步研究古代女性文学的两大特点：一是创作主体由前期的贵族才女、官妇到后期的文学世家，创作格调高雅清婉；二是思想内容由前期的&闺怨&题材到后期明清时期的表现女性意识和追求个性解放、男女平等的理想，具有进步意义。

The results shows that the tapetal expanding abnormally occurs in dyadphase stage, microspore abortion occurs in the early of monokaryon stage, disaggregation in the end of monokaryon stage, only some spall of microspore is observed in monokaryon stage, the four cell walls also exist, the tapetal cells became completely vacuolated, almost filled the whole locule. vascular bundle of male sterile line anther vanish at mature pollen stage.

结果发现花药绒粘层在二分体时期发生异常，小孢子在单核前期开始败育，至单核后期完全解体，花药发育后期不育系药腔中只观察到少量的小孢子残体，花药壁的四层细胞依然存在，绒粘层细胞已经彻底液泡化，占据了药腔的整个空间，花粉成熟期不育系花药维管束消失。

In the process of mining, much research was conducted on the control and reduction of the radiation hazards in underground uraniferous coal mine.

我国煤型铀矿资源的储量在我国铀矿资源总储量中占有一定比例。20世纪60年代后期我国开始了这类铀矿床的地下开采，在开采期间，对控制这类铀矿床地下开采中辐射危害的技术与管理措施开展了大量研究。20世纪80年代后期，因为多种原因，这类矿山被关闭。

Ecologists pointed out that a cluster of tall buildings in a overburdens city often overburdens public transportation and parking lot capacities.

The content of Z+ZR rose obviously and descended rapidly before and when gall started on swelling, respectively. The content of IAA in leaves was descending from anaphase to telophase of gall's swelling. The content of ABA in leaves was raised just before gall's swelling and that in sheathes was raised in anaphase of the gall' swelling, but there's no visible change in culm. There was no obvious change of GA 3 content in all parts and during growth and development.

其中 Z+ZR 含量在肉质茎膨大前即已明显上升，膨大开始后显著下降； IAA 含量在肉质茎膨大后期至末期才出现下降；叶片内 ABA 含量在肉质茎膨大前即开始上升，叶鞘内 ABA 含量在肉质茎膨大后期上升，茎尖内则无明显变化；各部位 GA 3 含量在整个生育期内无明显变化。

The data from stress box indicate that the observed values usually are smaller than the theoretical ones, and the relationship between the vertical or lateral stress and the fill soil thickness can be described in a power function curve: a- a hb. The fact that the soil stress is bigger in the portion adjacent to the central part of gully and becomes smaller in the portion close to the side illustrates that the gully has an apparent unburdening effect. From the monitoring results of the settlement deformation during and after constructingperiod, the study conducts statistical system analysis and evaluation on the change of settlement with time.
