查询词典 fundamental lemma of calculus of variation

Based on a delay-dependent bounded real lemma, the condition under which a decentralized robust H(subscript ∞) output feedback controller exists is derived and it is available to be attributed to a solution to the problem of nonlinear matrix inequality which can be expressed in terms of a homotopy function properly selected. Then, with the homotopic iteration method and the Schur complement lemma introduced, the solution can be converted into an iterative solution to the linear matrix inequality.

基于一个时滞依赖有界实引理，将系统鲁棒分散H动态输出反馈控制器的解归结为一个非线性矩阵不等式的求解问题；选取适当的同伦函数来表示该非线性矩阵不等式，采用同伦迭代算法及Schur补引理，将求解非线性矩阵不等式转化为线性矩阵不等式的迭代求解问题。

Finally, a basic lemma was given to reveal the relation between the solution set of a centain integral equations and the generalized cyclic invariant subspace. This lemma will play an important role in the determination of controllability.

然后以一个基本引理的形式揭式某一积分方程的解集与广义循环不变子空间之间的联系，这个引理将在能控性的判定中起关键作用。

Secondly, we give an important lemma. This lemma is the basis of this paper and also has an independent sense.

然后我们给出一个重要的引理，它不仅是本文的基础，而且这个引理还具有独立的意义。

The most important part is to show that Lemma 3 will follow if we can prove Lemma 3' and that part is quick.

最重要的一点是如果我们可以证明引理3'，则可以直接推出引理3。

The morphogenesis of floral organs in both srg mutant and wild-type rice Dular (Oryza sativa L.) was observed using the scanning electron microscope. The results showed that the floral primordia were differentiated under irregular pattern in srg mutant. After regular formation of lemma and palea primordia, the floral primordium of srg formed lodicule primordia inner to both lemma and palea, followed by the formation of stamens and carpel. Alternatively, floral primordia in srg were split to form two or more floral primordia. The number and position of stamens and carpels primordia were malformed.

利用扫描电子显微镜观察野生型水稻和裂颖水稻的颖花原基分化情况，结果发现，突变体水稻的幼穗在形成内、外稃原基后，有些颖花在形成浆片后并不是直接发育形成雄蕊原基，而是在外稃或内稃原基内侧又分化出浆片原基；有些颖花原基从中间缢裂，缢裂的颖花原基又分别形成类稃片的结构，颖花发育后期，6枚雄蕊发育畸形，并且观察到不同数目的雄蕊。

Sessile spikelet lanceolate, 4–5 × 1.2–1.4 mm; lower glume leathery with expanded rounded flanks below middle, herbaceous, strongly veined and sharply 2-keeled above, glabrous or villous, keels usually winged, apex 2-toothed; upper glume attenuate into mucro or awnlet to 2 mm; awn of upper lemma 1.2–1.5 cm.
