湖南城步铺头黄铁矿床的沉积环境晋东南煤系沉积黄铁矿层硫磺细菌的发现与扫描研究

Discovery of sulphur bacteria in pyrite ore beds of coal-bearing strata in the southeast of Shanxi and its study with scanning electron microscope

谈论这个话题时小点声，并且准备好面对铺头盖脸而来的、说你传播异端邪说的指责。不过，这种做法可能是一笔物有所值的交易。

Whisper it quietly , and be prepared for accusations of heresy to rain down on your head , but that might be a deal worth making .

PLC控制系统可实现功能顺序控制、剪切次数计数、显示电机转速等功能；验证实验表明：铺丝头试验台能够可靠地完成纤维的剪切、压紧和重送主要功能，达到了预期要求。

PLC control program can achieves the function sequence control , cutting counting and showing the motor speed . Validation experiment shows that the fiber placement head devised can reliably complete the main function of cutting , pressing and retransmission which achieves the desired requirements .

同时铺放头还具有将预浸纤维束加热的功能。

Also , the fiber tows are heated in placement head .

新型纤维铺放头的方案设计与实验研究

Schematic design and experimental research of a new fiber placement head

本文提出了一种新型的纤维铺放头总体机构和控制方案。

A new mechanical and control scheme of the fiber placement head is designed .

该铺放头是装在通用的铺放机上，完成铺放。

The placement head installed in a placement machine with the seven degrees of freedom , completes placement task .

它包括8个轴，在机身上安装了6个轴（包括3个直线运动轴和3个旋转轴），在铺放头内安装了两个轴。

It include 8 movement axis . There are 6 in the machine ( 3 linear axis and 3 rotatable axis ) and the other 2 axis in the placement head .

通过深入分析铺丝头剪切、压紧和重送等主要功能的实现过程，掌握各机构的功能要求。

The realization process of the main functions such as cutting , pressing and retransmission function of the fiber placement head is analyzed to acquire the requirements the functional devices should meet .

面向网状结构的芯模，在铺放头压头的伸出长度和宽度方面做好控制，使其能够做出灵活的调整。另外，丝束的切割模块在精确铺放中起着重要的作用。

Functional modules for grid-oriented but also the network structure of the core mold , do a good job in laying head to head stretched out the length and width control to enable them to make flexible adjustments .

有时我心里实在难受，便一个人躲在房里哭，或者倒在床上用铺盖蒙住头哭，害怕人听见哭声。

Sometimes , when the misery is more than I can bear , I hide alone in my room and cry , covering my head with the bedding so that no one will hear .

一个星期后，这个家伙又从理发铺外探进头问，“什么时候才能轮到我理发？”

A week later the same guy sticks his head in the shop and asks ," How long before I can get a haircut ?"

这样铺放机可以控制铺放头到达空间的任意位置进行铺放。

Therefore , the placement machine can control placement head to place fiber in any position .

在纤维铺放成型技术中，主要采用铺放头机构实现纤维的铺放。

Stripper mechanism The technology of fiber placement molding mainly uses the assembly of placement delivery head .

铺放设备的丝束铺放工作主要由铺放头完成，因此丝束增减控制是铺放控制系统研究的重点。

Control of tows increase or decrease is the focus in the study of a placement control system because the tow placement of a fiber placement machine is mainly performed by the fiber placement head .

复合材料铺丝束成型技术中铺丝轨迹的规划，主要解决铺丝头在芯模表面运动时的路径问题。

Purpose of trajectory planning of Automatic Fiber Placement of composite materials is for getting the trajectory of the head on model surface .

按照铺放8路纤维的要求，将各功能模块合理组合成完整的铺丝头结构。

The fiber placement head is devised through combining the functional devices reasonably following the idea of 8 fibers placement .

纤维铺放机的各个运动轴都是在数控系统控制下协同运动的，这样数控系统可以控制铺放机的铺放头到达空间的任意位置进行铺放。

Each axis of fiber placement machine cooperatively moves under control of CNC system , which can make the fiber placement head arrive at arbitrary location in space for placement .
