查询词典 H-hour

The topological structure of a new type of static synchronous compensator, which consists of traditional 12-pulse converter and a cascaded H-bridge, is presented. The purpose of designing such a topological structure, which integrates the concepts of multi-level, soft-switching and re-injection, is to reduce the voltage harmonic content at AC side and to solve dynamic voltage balance among the switches connected in series.

The S-PEU as well as H-PEU had a soft segment-rich surface as shown by ESCA study. The recalcification times for S-PEU and H-PEU increased 20% and 100%, respectively,as compared with that of ungrafted PEU.

A dye recycled photosensitization system has been designed. As a result of studies in the mechanism of electron transfer reaction of xanthene iodonium salt, it is proposed that the dye-recycled process consists of three-step reactions during the photosensitization: The oxidative fading product of dye is formed through electron transfer under irradiation; In the presence of H-donor, product changes into acidic leuco dye product; Product undergoes deprotonization under action of base to regenerate initial dye.

本文设计了染料循环再生的光敏反应体系，通过对占吨碘翁盐电子反应机制的深入研究，提出了占吨染料在光敏反应过程中的染料再生循环，它依次由三个反应过程组成：在光作用下，通过电子转移反应，产生染料氧化褪色体；在H给体存在下，通过H转移反应，使产物转化为染料酸式隐色体；在碱作用下，发生去质子反应，染料再生回复到染料的起始结构。

The whole production process was as follows: fresh strawberry fruits after the extirpation of sepal and rachisbranch steeped in 0.5 ‰ potassium permanganate solution for 20 h and then washed by clean water, then after 15 h gelatin treatment by compound zymin, the fruits were used for fermentation, and the indexes of the produced wine reached the standards of quality wine.

It was found that the asymmetric induction level of H〓-MAP was exclusively higher than that of corresponding MAP. Under the optimized reaction conditions, the allylation product could be obtained in up to 90.9% ee with H〓-MAP having 3, 5-xylyls as chiral inducer.

Results The UV-B treatment caused the declines of chlorophyll content, soluble protein content and water content of leaves, besides, dose-effect was existed. The decline of 30 μW/cm^2 treatment was bigger than that of 15 μW/cm^2 treatment. The influences of UV-B radiation on carotenoid content and anthocyanidin content were similar; the change trends were declined firstly then increased. The UV-B treatment with two doses restrained the electron transport of PSⅡ, particularly; the inhibitory effect was biggest after treated 2h, and then this effect was declined in 4, 6 and 8 h, so the dose-effect was existed. The UV-B radiation with two doses restricted photosynthetic rate and the inhibitory effect increased with the increase of treatment time. The high dose treatment caused huge damage to membrane system, while the result of low dose treatment was not obvious.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
