Lung cancer is a kind of commonly seen malignant tumor around the world,and it seriously threatens people′s health.Recent years have witnessed the increase of incidence and mortality of lung cancer.Many patients have already been in advanced stage with metastasis when diagnosed,missing the best operation time.Over the past few years,many treatments were used for advanced lung cancer,including the combined using of radiotherapy,chemotherapy,ablation and immunotherapy etc.This article summarizes the combined treatments for advanced non-small cell lung cancer that were commonly used in clinic.

The author participates in buildding work of 1580 hot mill of Ansteel subsidiary company,And complete programming and debugging of sizing slab press.Find questions of speed control in cold debugging,the handle measures is put forward and make SP debugging success.

This paper,The technical parameter and computer hardware system of automatic shape control,of Anshan steel own building the 3rd Making Steel & Rolling 2150mm Mill are analyzed.The control strategy of working roll′s shift and bender was described.In addition,shape feed forward control,flatness feedback control,crown feedback control(This control wasn′t applied because of crown gauge sampling lowly frequency before) and bran-new decoupling of shape and thickness model was set-up,also,on-line programming and debugging were proceeded.The statistical results of large amount of production data indicate that the crown and flatness control precision has been improved greatly after automatic shape control used.

鞍钢1780热轧生产线的厚度控制系统是从日本引进的.针对其中的数字控制系统进行了分析,阐述了厚度控制软件的设计思想及组成,对引进技术的消化吸收有一定意义.
