Mn-complexes in which Mn atom ligand with the N atom within ligand can stimulate the recovery of electron transfer and oxygen evolution. The trinuclear Mn-complex is extremely sensitive to the addition of CaCl2. It is suggested that there is an interaction between Ca2 and carboxyl within the trinuclear Mn-complex during photoactivation and this interaction benefits the ligation of Mn atom to the apo-WOC and form an active WOC. Binuclear MnMn complex shows slightly higher efficiency than binuclear MnMn complex in restoration of O2 evolution activity. It is suggested from our results that recovery of electron transport and O2 evolution with synthetic Mn-complexes is affected by different factors. Cl- can stimulate the reconstitution of WOC at the concentration of over 100mM;the maximal recovery of O2 evolution activity requires the presence of CaCl2 and 33 kDa protein polypeptide together. Bicarbonate can stimulate the reconstitution of WOC.

锰配合物中锰原子与配体中的氮原子配位连接时，能显著恢复电子传递活性和放氧活性；三核锰化合物在重组时对CaCl2的存在非常敏感，我们认为Ca2 与三核锰化合物中的羧基之间存在一定的相互作用，而这种作用有助于锰原子的光配位进而使三核锰化合物易于组装成有活性的水氧化复合物：双核锰化合物MnMn比双核锰化合物MnMn在恢复放氧活性方面更有效；影响锰化合物电子传递能力恢复的因素与影响锰化合物放氧活性恢复的因素不同；在锰蔟重组过程中，氯离子的浓度必须在100mM以上，才能有效进行光重组；最大光重组效率的获得必须有钙离子和33kDa多肽同时存在；碳酸氢根离子促进锰化合物与去锰光系统II的光组装。

Based on Ontology, the Chinese language teaching should guide students to experience individually and ideally and live poetically.

语文教学要回归存在本身，引导学生体验人的存在及人作为存在的意义，追寻理想化的生存状态，诗意地栖居在这个大地上。

Under some proper conditions we prove the existence of optimal controls in the class of Lipschitz functions, and obtain an optimality condition looks somehow like Pontryagin's maximum principle for a smooth optimal control function.

在适当的假设条件下，我们证明了状态方程解的存在唯一性和最优控制的存在性；并且根据最有控制函数的光滑性进一步对最优化存在的必要条件进行分析。

By means of the semigroup theory, spectrum theory, positive cone theory, integrated equation theory and optimal control theory, we obtain the existence of thresholds of these models, the existence and stability of the infection- free equilibrium and the endemic steady state, and the existence of optimal vaccination strategies, etc.

运用泛函分析中的半群理论、谱理论、正锥理论以及积分方程理论和最优控制理论，系统地研究了这些模型的阈值的存在性，无病平衡态和地方病平衡态的存在性和稳定性，最优接种疫苗策略的存在性等。

Keeping in mind that the One True Lord Existed before Creation, and that therefore essentially all modern Theologians accept that Jesus Pre-Existed Mary, this Pre-Existent Lord then had one major issue to resolve regarding how He might join human society .

铭记着一个真正的上帝创造之前存在的，因而基本上所有的现代神学家接受耶稣前存在的玛丽，这个前存在的主，然后有一个主要的问题就如何解决他可能加入人类社会。

Heidegger describes the circularity in the process of reasoning about Being in the following:"Phenomenological interpretation must make it possible for Dasein itself to disclose things primordially; it must, as it were, let Dasein interpret itself."

海德格尔这样描述关于存在的理性过程的循环："现象学解释一方面要存在自身揭示事物的原貌，一方面又要存在解释自身"。

There are many skin folds in human body which are adapted to the need of movementand also the important marks to divide anatomic regions.i.e.the groin is the skin fold whichexists between lower abdomen and anterior thigh,the gluteal-thigh sulcus is skin fold whichexists between buttocks and posterior thigh.Correspondingly,the skin fold which existsbetween pudendum and superior-medial thigh is named pudendal-thigh sulcus,and flapsharvested from pudendal-thigh territories can be called the pudendal-thigh flaps.

人体体表有许多皱褶，这些皱褶是为了适应运动的需要，同时也是解剖学分区的重要体表标志，如存在于下腹部与股前区的皮肤皱襞称为腹股沟，存在于臀部与股后区的皮肤皱襞称为臀沟，相应地，存在于大腿内上方与会阴部之间的皮肤皱褶可称之为阴股沟(pudendal-thigh sulcus)，在阴股沟区切取的皮瓣即称为阴股沟皮瓣(the pudendal-thighflap)。

Similarly, it makes little sense to ask when the Pythagorean theorem came to exist. And if it does make sense to ask, the only sensible answer is that it has always existed, or perhaps, that it does not exist 'in time' at all.

类似的，追问勾股律什么时候开始存在，是没有多少意义的；或者，如果追问有意义，仅有的回答是它一直存在，或，或许它根本不存在"在时间里"。

We first introduced a new concept called transitive resolvable idempotent symmetric quasigroup, proved that the necessary condition for the existence of TRISQ is also sufficient, then presented a tripling construction for LKTS by using TRISQ instead of TKTS, thus removed the condition "there exists a TKTS" in Denniston''s tripling construction for LKTS; We also improved J. Lei''s product construction for LKTS by removing the condition "there exists a TKTS".

我们首先引入了可迁可分解幂等对称拟群的新概念，证明了TRISQ存在的必要条件也是充分的，然后给出了用TRISQ取代可迁Kirkamns三元系的LKTS的三倍构造法，这样就去掉了在Denniston的关于LKTS的3倍构造中的条件"存在一个TKTS"；我们用TRISQ取代TKTS改进了雷建国的关于LKTS的一个积构造方法，从而去掉了该构造方法中的条件"存在一个TKTS"。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
