查询词典 valid function

The temporal variable "Now" always presents in HRDM or BCDM , while "UC" presents only in BCDM, HRDM is TDB which can represent valid time, while BCDM is a bitemporal database model which can represent both valid time and transaction time.

"All valid questions, all valid questions... We will meet here again, maybe then it will be time for answers," he replied, fading ephemerally into the surrounding darkness as he spoke.

&所有的这些好问题，所有这些问题…我们还会再在这里见面的，到时候也许会是个回答问题的好时候，&他答道，同时几乎瞬间隐入了周围的黑暗中。

In 1966, Ross solved the equation of symmetrical free vibration and got six matching solution, but he believed that it is impossible to find a solution which is useful in everywhere. In 1979, Goldenveizer printed a monography in which the uniformly valid representations of curved solution were published, but the representations of membrane solution were still not found. In 1988, Ruo-jing Zhang published the uniformly valid representation of six solutions for symmetrical free vibration and eight solutions for dissymmetrical free vibration for the first time.

但却碰到巨大困难。1966年，Ross给出了轴对称振动的6个匹配解，但却认为不可能求出全域一致有效解。1979年，Gol&denveizer等出版专著，给出了弯曲解的全域一致有效表达式，但仍然没有得到6个解中奇异薄膜解的全域一致有效表达式。1988年，张若京在其博士论文中第一次给出了轴对称6个解和非轴对称8个解的全部&全域一致有效表达式。

A ruling by the Commission, using its plenary power,(1) that a work is to be deemed, for nomenclatural purposes, as unpublished, or that names and acts in it are not available; or (2) that an available name is never to be used as valid because it is available only for the purpose of homonymy ("partial suppression") or it is not available for the purposes of priority and homonymy ("total suppression"; but a totally suppressed species-group name may still denote the type species of a nominal genus or subgenus [Art. 81.2.1]); or (3) that an available name is only to be used as valid under stated conditions (e.g. when not considered a synonym of a particular later name)("conditional suppression").

委员会使用其全权，以裁决(1)基於命名法的意冒，一著作物为未出版，或其中的名称和举动为不适用；或(2)一个适用名称永不得作为一个有效名称，因为该名称仅基於异物同名的意旨时始称适用，或基於优先权和异物同名关系的意旨而不适用(&完全禁制&；但是一个被完全禁制的种群名称仍可指示一个命名属或亚属的模式种[第81条2.1])；或(3)一个适用名称仅在申明的条件下用作有效名称(例如在不被认为是一个特别的较后名称的同物异名时)。

Our interpretation of the results from parsimony, distance and maximum likelihood based phylogenetic analyses suggest:(1) African colobines and Asian colobines have been independent evolutionary entities for a long time; the divergent time is estimated to occur 10 million years ago based on a molecular clock of 2% substitution per site per million years;(2) both Rhinopithecus and Trachypithecus could be regarded as separate genus;(3) Pygathrix and Rhinopithecus are sister groups while Presbytis and Trachypithecus are closely related;(4) both the Sichuan and Yunnan snub-nosed monkey represent valid species respectively;(5) within genus Trachypithecus, T. phayrei is closely related to T. cristatus and T. auratus, while T. francoisi is distinct from them; the white-headed leaf monkey, however, should be a subspecies of T. francoisi;(6) within genus Presbytis, P. thomasi should be separated as a valid species from P. melalophos, but the genetically divergent degree between P. comata and P. melalophos implies that P. comata may just be a subspecies of P. melalophos.

结果表明：（1）非洲疣猴与亚洲疣猴的分歧已非常明显，按分子钟推算的分歧时间约在1，000万年前；（2）Rhinopithecus和Trachypithecus均应成为独立的属；（3）白臀叶猴属与金丝猴属关系较近，Presbytis属和Trachypithecus属关系也较近；（4）我国的川、滇金丝猴应分别被视为独立的物种；（5）在Trachypithecus属中，菲氏叶猴与银叶猴(T.cristatus)和乌木叶猴亲缘关系较近，黑叶猴(T.francoisi)则与它们的关系较远，曾被怀疑为一个种的白头叶猴(T.f.leucocephalus)应只是黑叶猴的一个亚种；（6）在Presbytis属内，托氏叶猴应从僧帽叶猴(P.melalophos)中独立出来成为一个有效种，但我们的结果倾向于将灰发叶猴置为僧帽叶猴的一个亚种。

The fundamental properties of the system K are studied,and it is pointed out that All theorems of the system L are theorems of the system K.Some important theorems about quantifiers are obtained.Moreover,the following results also are proved that all instances of substitution in the system K of tautologies of the system L are logically valid for any R0 chain,the soundness theorem and strong soundness theorem hold in the system K,i.e.,all theorems ofthe system K also logically valid for any R0 chain.

其次，研究了系统K*的基本性质，指出了系统L*的定理都是系统K*的定理，给出了系统K*与量词有关的一些重要定理，证明了系统L*的重言式在系统K*中的代换实例都是系统K*中关于任何R0链的逻辑有效公式；系统K*的可靠性定理成立，即系统K*中的定理关于任何R0链也是逻辑有效的；系统K*的强可靠性定理也成立，即系统K*在任何理论T下的定理关于任何R0链也是逻辑有效的。

Letters of credit, bank guarantees and tender bonds shall be valid for one calendar month beyond the valid ity of the tender.

At start up the .Net Runtime tries to contact crl.microsoft.com to ensure that the cert is valid(there were some fake certs issued in Microsoft's name a while back so this is a very valid concern).

当打开SSMS的时候（特指&检查发行商的证书吊销状态&被勾选），。net Runtime 尝试连接到 crl.microsoft.com 确定证书是否有效（有一些伪造的证书是使用 Microsoft 这个名字的，所以这个是一个非常有效的方法）。
