We have obtained the following main significant results:(1) A master constraint operator for LQG is constructed, which is shown to be self-adjoint in the diffeomorphism invariant Hilbert space. Thus it lays a foundation for the master contraint programme in LQG;(2) The Immirzi parameter ambiguity in LQG is fixed by introducing supersymmetry, which leads to the conclusion that in the case where matter fields are coupled LQG might prefer supersymmetry in low energy;(3) The current accelerating expansion of our universe is successfully explained in the context of 5-dimensional Brans-Dicke theory, which gives a natural strategy to solve the dark energy problem.

重要成果包括：(1)构造出圈量子引力的Master约束算符，并证明了其自伴性，从而为应用Master约束方法解决量子动力学的难题奠定了基础；(2)通过引入超对称合理地固定了Immirzi参数，得出了在与物质场耦合的低能情况下圈量子引力可能偏爱超对称的结论；(3)用五维Brans-Dicke理论成功地解释了当今宇宙的加速膨胀，从而给出了一个自然解决暗能量问题的方案。

其他的分类特征有藻类储藏物质的特征，细胞壁的类型，波动足的类型和数量，细胞超微结构，食物储藏的类型，生殖过程等。

The ultrafast laser technology is expanding to new waveband as well as to a less during time.

不断深入的研究工作则要求超短激光技术继续朝着更短的脉冲持续时间和新的激光波段发展，这一般可通过飞秒激光同物质的非线性相互作用得到。

At the same time, with the rapid development of the ultrashort-laser-pulse technology, the focusable intensity of 10〓W/cm〓 can be realized on a compact table-top laser system, which can support the electric field that is much higher than that in H atom.

同时，随着超短超强激光技术的飞速发展，目前在小型化台式激光系统上，可聚焦功率密度已经达到了～10〓W/cm〓的量级，在这种功率密度下，激光场强度已经远远超过氢原子的内部库仑场强，激光与物质的相互作用已经进入极端非线性的领域。

从糠醛出发，由制备的糠酸和甲醇反应，在盐酸催化下，合成了香料糠酸甲酯，并用IR、1HNMR、GC等进行了表征；探讨了包括高纯度糠酸的制备在内的反应影响因素，在醇酸物质的量之比为 5∶1、催化剂体积占甲醇体积 13.0 %、反应时间 3h的最佳工艺条件下，酯化收率为81 0 %，收率比硫酸法、某些固体超强酸法

Because the core mass of the AGB star is remarkably large at low metallicity.

对于AGB星初始质量小于3M_☉且初始轨道距离较远的双星系统，白矮星不能从受污染的星上吸积充足的物质，因此不能形成AIC，其伴星只受到AGB前身星的污染，从而形成s-过程元素超丰的星。

The group plans to build, in just three years, a hyperefficient, supersafe four-passenger to six-passenger car called VDS Vision that will be produced and used with 95 percent less energy and toxic materials throughout its lifetime than an average existing vehicle.

这群大学师生打算在短短三年时间里就造出一种高效能、超安全的四人座至六人座小汽车，取名为VDS Vision。与现有的一般车辆相比，这种新型汽车在其整个使用期内可减少95%的能源消耗和有害物质的排放。

Already the very foundation of her own life's work had been shaken by what she had uncovered in Haydon's transphysical musings, and all at once she felt too unsure of herself and her ambitions to permit much more in the way of contradiction.

她自己生命形态工作的真正根基已经被她对海顿的超物质冥想的不了解所动摇了，而突然之间她感到对她自己和她的抱负不太自信，以致不能允许更多的反对。

Methods: Serum-free conditioned media of Schwann cell cultures from facial and sciatic nerves of neonatal and Wallerian degenerating segments in adult rats were individually collected and concentrated by ultra-filtration with molecular weight cut-off at 30 000 and 10 000. The growth activities of FMNs in vitro were determined by means of MTT assay under the condition of serum-free medium added with different components of concentrated SC-CMs.
