Ch'i-ch'iao bowed her head, basking in glory, in the soft music of his voice and the delicate pleasure of this occasion. So many years now, she had been playing hide-and-seek with him and never could get close, and there had still been a day like this in store for her.

七巧低著头，沐浴在光辉里，细细的音乐，细细的喜悦……这些年了，她跟他捉迷藏似的，只是近不得身，原来还有今天！

Khoja Affāq also had other noteworthy contacts in China, the most important of these being Ch'i Ching-i (1656-1719), who established the Qadiri path in northwest China. Ch'i Ching-i went to Hsi-ning to study with Khoja Afāq in 1672, but the khoja sent him home, saying,"Your teacher is on his way; just go back home quickly."

马瓦拉纳合的纳格什班底耶在一定程度上将这些重要的操行和阿勒特沙的纳格什班底耶进行了交流，而后者可能随着神秘道路的向东传播，将具有这些特征的操行带到了中国汉人区和西藏地区东北部。

Then comes the more powerful CH-47B with the Lycoming T55-L7C engine, which was introduced by Boeing after a production run of over 350 CH-47A's. On the B model there are nonsymmetrical rotor blades to increase the stability.

因此波音公司在推生产了350架CH-47A后，推出了更加强劲的配备莱克明T55-L7C发动机的CH-47B型。B型为提高稳定性，还配备了非对称性的旋翼桨叶。

Both overlong or overshort bottom duration and overlong or overshort fluctuation period are unfavorable for reduction of non-diamond content. Only moderate ones have optimal effects on it.3 Compared with a smooth microwave, a fluctuating one can reduce the diamond nucleation density slightly.4 In fluctuating microwave, even if a higher CH〓 concentration chosen, diamond films with quality better than that of those deposited at a lower CH〓 concentration and in smooth microwave can be obtained.In smooth microwave, the influence of O〓 upon the diamond films＇MWPCVD was investigated. It is found that:1 In the range of lower O〓 concentration, its increase is beneficial to improvement of quality of diamond films, but in that of higher one, its increase conversely deteriorates the quality of diamond films.

在脉动微波下进行了沉积金刚石膜的研究，得到下述结果：1）采用合适的脉动微波，能使金刚石膜的沉积质量显著提高，并能使金刚石膜中的微晶石墨得到几乎完全的抑制。2）过长或过短的平底时间或脉动周期均不利于金刚石膜中非金刚石相碳含量的降低，只有适中的平底时间或脉动周期才有最佳的降低非金刚石相碳含量的效果。3）脉动微波会使金刚石的形核密度有所下降。4）脉动微波下，即使选用较高的CH〓浓度，也能得到沉积质量比在平稳微波下采用较低的CH〓浓度所制备的金刚石膜的沉积质量要明显提高的金刚石膜。

In fluctuating microwave, deposition of diamond films was investigated and some significant results were obtained:1 An appropriate fluctuating microwave can distinctly improve the quality of diamond films, and can grow diamond films almost without microcrystalline graphite.2 Both overlong or overshort bottom duration and overlong or overshort fluctuation period are unfavorable for reduction of non-diamond content. Only moderate ones have optimal effects on it.3 Compared with a smooth microwave, a fluctuating one can reduce the diamond nucleation density slightly.4 In fluctuating microwave, even if a higher CH〓 concentration chosen, diamond films with quality better than that of those deposited at a lower CH〓 concentration and in smooth microwave can be obtained.
