METHODS:Two hundred and seventy-one eyes of 219 patients with hard nucleus cataract, grading level IV or V, were operated with anteroposterior interceptive chop method for splitting the nucleus, and then with phacoemulsification. RESULTS:The hard nucleus of the 271 eyes were successfully routed. The average phaco time was 57.4 s.

对219例(271眼)级以上硬核白内障采取前后夹击劈核法，经充分水分离和水分层，吸除硬核前的皮质及软核后，乳化头退至前囊口上缘，劈核器轻压核下方，停止灌注让核上缘随前房变浅脱出囊袋口，乳化头顺势抵住核上缘，灌注加深前房后，乳化头滑入核后面，劈核器置核前面，前后夹击将核劈碎乳化吸出。

The opening of leptomeningeal anastomoses vessel is the important way of collateral circulation in cases of serious stenosis or occlusion of MCA,the collateral flow between MCA and ACA is dominant. The RVACA/RVPCA can reflect the hemodynamic changes、the state of leptomeningeal anastomoses vessel when the MCA was serious stenosis or occlusion; There was a inverse correlation negative correlation between the RVACA/RVPCA and the NIHSS.

⑴在MCA中度以上狭窄或闭塞的情况下，皮质软脑膜吻合血管开放成为侧支循环的主要途径，以MCA-ACA之间的代偿为主；⑵RVACA和RVPCA在一定程度上可以反映MCA狭窄或闭塞时颅内血流动力学的改变、软脑膜侧支吻合的功能状况及有效程度；⑶RVACA和RVPCA与患者的NIHSS评分呈负相关，RVACA和RVPCA值越高的患者，其神经功能缺损程度越轻。

My world then -- silent, soft, and vegetable-like in its vulnerability, subject to the powerful whims of others, diurnal, beginning with the pale opening of light on the horizon each morning and ending with the sudden onset of dark at the beginning of each night -- was both a mystery to me and the source of much pleasure: I loved the face of a gray sky, porous, grainy, wet, following me to school for mornings on end, sending down on me soft arrows of water; the face of that same sky when it was a hard, unsheltering blue, a backdrop for a cruel sun; the harsh heat that eventually became a part of me, like my blood; the overbearing trees (the stems of some of them the size of small trunks)...

当时我的世界--无声软，蔬菜类的脆弱性，受到强大的脸色他人昼夜、开初的苍白的地平线上轻每天早上为止突如其来的黑暗开始每晚--既不可思议的来源很高兴：我喜欢面对一个灰色的天空、多孔、粒、潮湿，早上上学后我就完，送我软下来的水箭；面对同样的天空当它是硬unsheltering蓝色，背景为太阳残忍；严酷的热，最终成了我的一部份，像我的血液；咄咄逼人树茎其中一些规模小树干

In this paper, a soft-switching technology scheme, which can be applied to vehicle-carried invertors, has been researched at the base of engineering practice .The principle and control strategies of soft-swiching are also discussed in detail. Furthermore, software and hardware components are discussed particularly by using shift phase control technology properly and the combination of DSP and IGBT.in result, the vehicle-carried invertors have the characteristics of small volume, light weight, high integration and high frequency.
