In the workshop has the filtration dust air-interchange system, the ultraviolet ray sterilizing lamp and the ozone sterilizing machine, had guaranteed dustlessness aseptic safety in production environment, the packing material clean between carries on first after the can cleanly, then arrives at the ozone disinfection warehouse to carry on the disinfection sterilization, guarantees the packing material safety and health.

车间内有过滤灰尘的换气系统，紫外线杀菌灯和臭氧消毒机，保证了无尘无菌的安全生产环境，包装材料先经过铁罐清洁间进行清洁，再到臭氧消毒仓进行消毒杀菌，确保包装材料的安全卫生。

This method is featured with high estimating performance and little computation burden by n o aperture losing and temporal smoothing. The reˉ quirements on hardware for RSDOA matrix method is predigested consu medly only need one fiducially sensor array with arbitrary structure and a single scattered sensor cell, so it is more effective and practical than other existing similar algoˉ rithms.

与现有算法相比较，RSDOA方法对于系统的硬件需求大为下降，计算负担小；由于无阵列孔径损失问题且空时协方差矢量具有时域平滑效果，因此参数估计性能优越，具有广泛的适用性与实际的应用价值。

In the meantime, unknown to NASA, GE was developing its own design: a gearless, counter-rotating pusher system.

而在同一时期，GE也在进行着自己的开发设计（不知为何，NASA对此并不知情）：一个无减速器的反向旋转的推进系统。

We studied an algorithm of tourism route analysis based on Tourism Geographic Information System using the technology of GIS, indirected graphs analysing and Dijkstra algorithm.

Based on conventional fuzzy control theory, an analysis of triangular partition fuzzy control is given to present several properties of TPFC: the fuzzy approximation mechanism, the approximation accuracy, entropy equalization, zero-error reconstruction and interpolative reasoning.

在研究经典模糊控制的基础上，本文分别从近似机理、精度分析、等熵设计、无偏差重构以及插值推理等不同角度对三角划分模糊控制进行了较系统的分析与研究，得出了用于HIFC设计与学习的一些重要结论。

Extant jawless vertebrates, represented by lampreys and hagfishes, have innate immune receptors with variable domains structurally resembling T/B-cell receptors. However, they lack cardinal elements of adaptive immunity shared by all jawed vertebrates: T/B-cell receptors and major histocompatibility complex molecules.

在以七鳃鳗和盲鳗为代表的无颌类脊椎动物中，虽然发现了与有颌类脊椎动物T细胞受体(T-cell receptors， TLRs)、B细胞受体(B-cell receptors， BCRs)可变区具有相似结构的先天性免疫受体，却从未发现有颌类脊椎动物适应性免疫系统的核心组分：TCRs、BCRs、组织相容性复合体(Major histocompatibility complex， MHC)。

The liveness is an important property for Petri net,and it is difficult to decide whether a Petri net is live or not.
