any man of mine 这是一个女人想要的…我钟意的男人最好以我为豪即使我丑得可以他最好照样爱我我约会迟到没什么大不了但他最好给我准时我钟意的男人该说正合身当去年的裙子不过略显紧了些我怎么发牢骚出怨气都行当我哪天走了霉运如果我改变主意千千万万次我要听到他说对，对，对，对，对，我就喜欢那样我钟意的男人最好别找麻烦最好秀我一段兴奋甜蜜惬意的时光我需要一个男人，懂得爱情的进程他得是那种让人心跳不止温柔体贴另人窒息惊天动地的那种我钟意的男人我钟意的男人最好否认当我说别的女人长得比我漂亮而当我为他做饭却烧糊了他最好说，恩，正合我的胃口如果我改变主意千千万万次我要听到他说对，对，对，对，对，我就喜欢那样我钟意的男人最好别找麻烦最好秀我一段兴奋甜蜜惬意的时光我需要一个男人，懂得爱情的进程他得是那种让人心跳不止温柔体贴另人窒息惊天动地的那种我钟意的男人让我听到你说对，对，对，对，对，我就喜欢那样我钟意的男人最好别找麻烦最好秀我一段兴奋甜蜜惬意的时光我需要一个男人，懂得爱情的进程他得是那种让人心跳不止温柔体贴另人窒息惊天动地的那种我钟意的男人你得可以震撼人心可使地动山摇踢腿，转身，蹬地，蹬地，然后跳步脚跟到脚尖，多西多直到跳破靴子直到脚酸背痛别停下直到你实在跳不动来吧所有站着的来-一二，来-三四来，二，来如果你想成为我钟意的男人，就这样这是一个女人想要的

The College of Abbreviators was restored, the Roman Academy was recognised, and Platina was appointed librarian. The manuscripts in the Vatican Library were increased, more ample accommodation was provided, and every facility was given to scholars to consult the papal collection.

In the design of the power supply, the main circuit topology frame uses full-bridge series resonant switching and parallel load connection, in which, four MOSFETs are adopted as the power switches, and by four pulses which UC3879 produces, high frequency operation and fast response are realized. In addition, the MOSFET in the switching power supply has no hard turn-on or turn-off situation in transition, thus the disturbance to the power system is avoided. Especially,by the use of high frequency transformer, PQ50/50, the switching power system can provide the steady discharge current without any amperite.

此开关电源采用全桥软开关技术、串联谐振并联输出，四个MOSFET管为主控制开关元件，通过脉冲产生电路UC3879产生的四路相关脉冲实现了高频交替开关，同时能快速响应输出的各种变化；避免了开关管的硬开关，提高了转换效率，另外通过采用高频变压器PQ50/50隔离了原副边，减小了高次谐波对电网干扰；无需镇流电阻也可实现气体稳定放电。

In this article, we used automotive immunohistochemical stainer to check the expressions of HBsAg and HCV antigens in 100 cases of HCC and their adjacent tissues, mean while, we checked their histological activity index and hepatic fibrosis degree. We also used radioimmunoassay to detect serum levels of 4 serum fibrosis markers and serum AFP levels in these cases. Immunofluorescence labeling and flow cytometry were used to check the T-cell subpopulations and the activity of NK cells of these 100 cases. Then the correlations among these factors were studied.
