By June of 2008, there were less than 80 fungal genomes that were completely or almost completely sequenced and publicly accessible representing the widest sampling of genomes from any eukaryotic kingdom. These genomes belonging to true fungi, Microsporidia and Oomyces vary in size from approximately 2.5 Mb to 81.5 Mb.

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.

A number of microplants with spherical, triangular, polyangular and boat-like shapes have been found both from the early Palaeoproterozoic Dashiling and Qingshicun Formations (ca. 2500- 2400 Ma) of the Doucun Subgroup of the Hutuo Group and the late Palaeoproterozoic Changzhougou and Chuanlinggou Formations (ca. 1800 -1700 Ma) of the Changcheng Group in North China. According to the features of these fossils, such as size, external shape and internal structure, they may belong to unicellular eucaryotic planktons.
