Using techniques of computer aided design and computer aided manufacture is important to reduce the time and the cost of developing progressive dies.

在多工位级进模领域采用计算机辅助设计与制造技术是克服传统模具生产方式周期长、成本高等缺点的一项重要工作。

In order to tackle the difficulties including the sidetracking, the reentrance of the main hole, the well bore trajectory control, and the poor drillability of the formation, some technologies are put forward, such as the sidetracking technology of compound holes, the pipe string reentrance technology of main holes, the well bore trajectory control technology, and the drilling speed increasing technology. All the technologies have been applied to the field successfully, greatly shortening the drilling cycle and guaranteeing the safe and fast completion of the well.

针对悬空侧钻、主井眼重入、井身轨迹控制和地层的可钻性差等多个技术难点，提出了复合井眼悬空侧钻技术、主井眼管柱重入技术、井身轨迹控制技术和钻井提速技术等方法，在现场应用中取得了显著效果，大大缩短了钻井周期，保证了安全快速完井。

Software test plays an important role during the software life cycle, which is realized by more and more software companies.

软件测试在软件生命周期内占有重要地位，这一点被越来越多的软件研发机构认识到。

Methods : We subjected C57BL/6J mice to CS (whole body exposure, 90 min/day) for various periods, and used laser capture microdissection to isolate bronchiolar epithelial cells for analysis of mRNA by quantitative reverse transcription-polymerase chain reaction.

研究方法：研究者将 C57BL/6J 小鼠分别在不同时间周期暴露于CS（全身暴露，90分钟/天），用激光捕获显微切割技术分离细支气管上皮细胞，然后用定量逆转录多聚酶链反应分析上皮细胞的mRNA。

A model used to simulating the deposit thickness overlapped by the deposit profiles of multiple circumrotate cycles was established. This model was applied to simulate the deposit thickness with different pitch of the deposit track, and the optimum condition of movement parameters was obtained under which homogeneous deposit surface can be prepared.

建立多旋转周期沉积轮廓叠加的单层沉积厚度模型，利用该模型在不同沉积轨迹螺距下，对沉积厚度进行计算仿真，获得保证均匀沉积面的运动参数优化条件。

In order to adapt the rhythm of the continuous casting, No.3 Steelmaking Plant of Jigang optimizes specific iron and steel structure, increases the percentage of goal hits of the converter, optimizes LF slag-making and argon blowing processes and intensifies LF deoxidation and desulphuration etc, shortening refining period 17min, reducing he electric consume 6.7kW.h/t.

为适应连铸节奏，济钢第三炼钢厂通过优化钢铁料结构、提高转炉终点命中率、优化LF造渣及吹氩工艺、强化LF脱氧、脱硫等措施，缩短精炼周期17min，降低精炼电耗6.7kW.h/t，满足了高附加值钢种的工艺要求并实现了多炉连浇。

In this study, we investigate how the cell cycle coordinates gastrulation cell movements in zebrafish.

一方面是细胞分裂/细胞周期，通过无数次的细胞分裂，胚胎发育从一个单细胞受精卵发育为多细胞成体。
