调波

The windings in the valve side adopt prolonged delta connection providing the circuit for three-multiple harmonic currents, and implementing 12-pulse converter through fit ratio; this connection between the common winding and prolonged winding can decrease the current impact when phase conversion takes place.

该换流变压器阀侧绕组采用延边三角形接线，为3倍次谐波电流提供通路；通过匝比配合，实现12脉波换流；其延边绕组与公共绕组构成自耦变压器接线，可减少换流器换向时的电流冲击；在公共绕组上连接滤波支路，并调至谐振点，配之以变压器巧妙的零阻抗设计，可以在阀侧实现无功补偿，可实现网侧绕组中无5、7、11、13次特征谐波，即谐波屏蔽。

Based on the ring-shaped laser-diode array side-pumped Nd:YLF high gain amplifier and the conventional plan-concave resonator, a simple structure single-longitudinal-mode single-pulse Q-switched oscillator is demonstrated by taking advantages of mode-selecting property of passive Q-switches (Cr4+:YAG crystal) and etalons (formed by two end of uncoated Nd:YLF rod).

以激光二极管环形阵列侧面抽运Nd：YLF棒高增益放大器模块为基础，在经典的平凹驻波腔中加入一片Cr4+：YAG晶体作为被动Q开关，利用被动Q开关本身所具有的振荡选模功能以及两端不镀膜的Nd：YLF棒所具有的标准具效应，简便地实现了稳定的单脉冲、单纵模调Q输出。

The chiefs disposed their men this way and that before the fight began, drafting them out as easily as goatherds draft their flocks when they have got mixed while feeding; and among them went King Agamemnon, with a head and face like Jove the lord of thunder, a waist like Mars, and a chest like that of Neptune.

军队排开战斗序列，像有经验的牧人，将大群的山羊——其时混合在一起，牧食在草野上——得体地分成首领们忙着分遣部队，有的调这，有的去那，作好进击的准备。强有力的阿伽门农迈步在他们中间，头眼宛如喜好雷霆的宙斯，摆着阿瑞斯的胸围，挺着波塞冬的胸脯。恰似牛群中的一头格外高大强健的雄杰

His musical talent was early apparent, and he gained a reputation in Warsaw as a "second Mozart." At age seven he was already the author of two polonaises, the first being published in the engraving workshop of Father Cybulski, director of a School of Organists and one of the few music publishers in Poland.

他的音乐天赋很早就显露出来，在华沙他赢得了&莫扎特第二&的美誉。7岁时他已经创作了两首波洛奈兹舞曲（ G 小调和降 B 大调），第一首在神父Cybulski的雕刻工作室首次发表，这位神父是手风琴学校的主管，也是波兰的少数音像出版商之一。
