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。

In the seedlings time, the content of chlorophyll decreased by the deficiency of B, but the content of chlorophyll in the high efficiency cultivar decreased slowly than that of the low efficiency cultivar. This suggested that the leaves of the high efficiency cultivar can capture more light energy and the photosynthetic rate of the high efficiency cultivar decreased slowly. In the bolting time and blooming time, after two weeks of B deficiency treatment, the content of chlorophyll in the top leaves of the high efficiency cultivar decreased, and in the late time, the content of chlorophyll decreased slowly. But, the content of chlorophyll in the bellow leaves of the two cultivars had little changes. The reason may be that B in the high efficiency cultivar distributed to the propagative organ in the late growth, and the leaves were short of B.

苗期，缺硼导致甘蓝型油菜色素含量降低，且高效品种色素含量下降的幅度小于低效品种，表明营养生长阶段，同等程度的缺硼条件下，高效品种叶片对光能的收集能力以及光合速率下降的程度相对较小；苔期和花期，在两周的缺硼处理后，高效品种上部叶色素含量依然呈下降趋势，但随着生育期的推移，其下降幅度减小；而高效品种下部叶和低效品种叶片含量变化不大，可能是甘蓝型油菜进入生殖生长阶段后，高效品种将硼更多地分配到繁殖器官，而其叶片却承受了相对较大的缺硼胁迫。

It was the better for ramet propagation in late April to late June, which can provide high yield.

冬前采用荒坡改梯土的整地方式产量最高，比移栽时荒坡改梯土增产40.5％，比移栽时荒坡鱼鳞式整地增产33.7％。

The Court ruled that CBE had no standing to sue Steel Company because any injury caused by the missed deadlines was not "redressable," a criterion needed to establish standing. Justice Scalia stated that the relief sought by CBE would not "serve to reimburse ... for losses caused by the late reporting, or to eliminate any effects of that late reporting upon respondent."

法院裁决 CBE 没有诉讼主体资格来起诉钢铁公司，因为任何一个由于超过最后期限引起的损害是不可以救济的，这就需要设立主体资格的标准， Scalia 法官认为 CBE 所寻找的这种救济不会&致力于赔偿由于近期的报告所造成的损失，或者减少任何近期报告对被告的影响&。

From late Jurassic-early Cretaceous to late Cretaceous, the magmatic activities decrease and the compositions of magmas change from shoshonitic and rhyolitic to alkaline basaltic.

从晚侏罗世—早白垩世早期到晚白垩世，中国东部岩浆作用明显减弱，岩浆成分从钾玄质和流纹质向碱性玄武质转变。

The late phase expression cassette suited for adenovirus vectors was also constructed. The HBV S gene, HBV preS2+S gene and the late phase expression cassette +HBV S genes were respectively cloned into the Ad5 vector downstream of the E3 promoter. Semiconfluent monolayers of 293 cells were cotransfected with the above constructed plasmids and Ad5 DNA EcoRI A fragment. The progeny adenoviruses named rAd5S, rAd5MS, rAd5S2S were harvested.

通过共转染优化实验，建立了脂质体转染腺病毒的有效方法，并构建了适合腺病毒载体的晚期表达盒，进一步将乙型肝炎表面抗原基因、HBV preS2+S、腺病毒晚期表达盒+HBV S基因插入E3区，与EcoRI消化的Ad5 DNA A片段共转染细胞，并获得重组腺病毒，相应命名为：rAd5S、rAd5MS、rAd5S2S。
