在 blue-shift之外的lmax、发射最大值也blue-shifted(从414到33海里的enol表格好吗从这种keto 519海里的，具有显著的形式)加强keto tautomer排放在集合。

The crystal structures of them show the photochromism is due to the photoisomerization only from enol form to keto form. According to the results of structure analyses, the intermolecular proton transfer mechanism is proposed for photochromism. We also observed their acidichromism in solution.

采用单晶XRD法得到了这五种化合物的结构，根据结构解析，推测四种光致变色化合物的变色机理可能是分子间质子转移，即吡唑啉酮由烯醇式结构变为酮式结构。

The reverse ESIPT can occur in the first triplet excited state (T1) to form the enol form which emits phosphorescence.

在第一三重激发态(T1)它还可以发生逆向的ESIPT而使T1态烯醇式发射磷光。

It was shownthat, among the three possible tautomers; i.e., the keto-form and the two enol forms, and thecorresponding enol anion, only the enol form 31 was actually responsible for the singletoxygen reactions.

用核磁共振及从头算法研究了化合物12b和23a在甲醇和吡啶中的烯醇化作用，结果表明，在其三种互变异构体以及相应烯醇负离子中，只有烯醇式31是实际参与单重态氧反应的成份。

The essential content of law is not simplex but the entia of freedom, right and power. The above three are the core and the footstone of law. However, the essential content of law has its own form which is the inner structural character. This kind of form belongs to the category of essence and it includes the norm nature, the universality, the obligation nature, the authority, the procedure nature and litigant ability of law.

法的本质内容不是单一的，而是自由、权利与权力这三元或三维要素的统一体，它们是法的核心内容、基石范畴；而法的本质内容是有其形式的，即法的内部结构特征，这种形式也属于本质范畴，它包括法的规范性及其普适性；法的义务性；法的权威性；法的程序性与可诉性；等等。

The results show that TaC with form of coating enwrap evenly and compactly around with the carbon fiber in C/C-TaC composites and form the cannular microstructure, both the average strength and toughness of C/C-TaC composites sample increase apparently.

结果表明：C/C-TaC复合材料中TaC以涂层形式均匀致密地包覆在炭纤维周围，形成管状微观结构，大大提高C/C-TaC复合材料试样的平均强度和韧性。

In this chapter the author expounded the origin of the concept of Free-form generators, pointed out that it is the certain result of the development of synchronous multi-axis CNC technology, explained the basic principle of the machining of extended epicycloid bevel gears on Free-form generators and the methods for both hardware and software implementation.

论文第2章是全文的基础，在这一章中，作者论述了Free-form型机床概念的由来，指出它是多轴联动数控技术发展的必然结果；阐述了Free-form型机床加工延伸外摆线锥齿轮的基本原理及其软硬件实现方式；将机床控制系统分解为包含两根虚拟主轴的有两组独立联动的八轴八联动系统；建立了Free－form型机床的数学模型；推导了展成运动速度、加速度及高阶加速度的表达式，为后续的理论分析奠定了基础。

Some, however, believe that an episcopal form of church government is the proper, or at least the allowable, form of organization.

不过，有些人认为，一个主教形式的教堂，政府是正确的，或者至少是可容许的，组织形式。
