During embryonic development, many animals form a number of temporary structures along their anterior-posterior axis-somites. Cells in somites differentiate into sclerotome, which gives rise to vertebral column, dermatome, which gives rise to dermis, and myotome, which gives rise to skeletal muscle.

He therefore adopted the plan of inserting the texts in the body of his general treatise; from the disordered mass of canons collected from the earliest days, he selected not only the law actually in force (eliminating the regulations which had fallen into desuetude, or which were revoked, or not of general application) but also the principles; he elaborated a system of law which, however incomplete, was nevertheless methodical.
因此,他通过了该计划的插入文本在身体其普通伤寒,从无序大规模的大炮收集到的最早的天,他选择了不只有法律才真正生效(消除规管,已陷入desuetude ,或被吊销或不普遍适用),而且还原则,他制定了一项法律制度,但是这不完整,尽管如此,有条不紊。

Next, in the scheme for teleportation of an arbitrary multipartite GHZ-class state by one EPR pair, only one EPR pair and 3 classical bits are needed, which greatly lessens the oppressiveness of both quantum and classical channels. Then, in the scheme for deterministic, unilateral and controlled teleportation via cavity QED, Alice can determinately send her state to anyone of her agents, whereas the agents can not, with the channel being noiseless. What the agents can do is just to control the teleporting process, which enhance the security of the communication.Besides,based on the schemes discussed above,it is easy to see the character of an entangled state which can accomplish deterministic teleportation via cavity QED.
利用一个EPR对实现n-体类-GHZ态的量子隐形传态方案,整个通讯过程只需要一个EPR对和3 cbits的经典信息,大大节省了物理资源,缓解信道压力;利用非对称类-W态实现确定的单向受控量子隐形传态,在没有噪声的条件下,Alice可以将量子信息准确无误地发送给任一个客户,但每一个客户只能控制配合整个信息的传输过程,客户之间不能实现确定的信息传递,这样便保证了信息的安全性。

In the property of a thing the negation takes the form of a specific determinateness, which is directly one with the immediacy of its being, an immediacy which, by this unity with negation, is universality. Qua "one", however, negation, the specific quality, takes a form in which it is freed from this unity with the object, and exists per se on its own account.
在特质那里,否定性是直接地和存在的直接性同一的规定性,而存在的直接性由于与否定性的同一,就是普遍性;但是当否定性摆脱了它与对方的这种统一而自在自为地存在着时,它就是单一。

The research shows that in the Yinggehai basin, the formation of CO_(2) reservoir which is crust-sourced and crust-mental-mixed-sourced, mainly controlled by local action of hot fluid in the mud diapir area which is multi terms and multi zones and by physical-chemical mechanism of very thick marine calcareous sandstone and mudstone of Pliocene-Miocene. The volcano- and mantle-sourced CO_(2) in the Qiongdongnan basin and Pearl River Mouth basin is mainly controlled by volcanos activities and by the exist of large faults which reached to base to connect the gas from the mantle. According to different mechanism ang formation of reservoir os the the crustal rock-chemical genesis and volcano-and mantle-sourced CO_(2), we can follow the source of it, analysis and predict the migration and accumulation and distribution model of gas and espacially CO_(2), so as to help to make the plan of petroleum exploration and reduce the risk of exploration.
认为:莺歌海盆地壳源型及壳幔混合型CO2的形成及富集成藏,主要受控于泥底辟热流体晚期分层、分块和多期的局部上侵活动,和巨厚的上新统—中新统海相含钙砂泥岩的物理化学综合作用,且CO2运聚分布规律亦具多期和分层、分区的特点;琼东南盆地东部及珠江口盆地火山幔源成因型CO2则主要受控于幔源型火山活动和沟通深部气源的基底深大断裂的导气配置作用,CO2运聚富集规律与幔源型火山活动及深大断裂的发育展布密切相关,CO2主要来自地壳深部幔源火山活动所伴生的大量CO2;因此,根据壳源岩石化学成因型CO2与火山幔源成因型CO2不同成因机理及成藏条件,可以追踪CO2气源,可分析和预测天然气尤其是CO2的运聚分布规律,可为天然气勘探部署及决策提供依据,可减少和降低勘探风险。

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。
