由于强调专业化茶园建设，集中成片，造成群落内植物种类单一，长期无树木遮荫和防护，夏日受烈日暴晒，冬天遭寒风侵袭，生态条件恶劣，自然灾害频繁，水土流失严重，土壤有机质含量低，土层浅薄，茶叶产量低，自然品质不佳。茶园生态系统的能量输入由过去的有机能如有机肥、人畜力等为主转向现在的化肥、农药、除草剂、生长激素、机械等石化能为主，这种能量的变化，虽然暂时提高了产量，但从长远来看，使环境质量降低，土壤结构僵化，土地报酬递减，同时大量施用化学氮肥，也导致茶树生育不健壮，减弱抵抗自然灾害的能力。 相似文献

Tension is very closely related with fabric inspection quality, as not well controlled tension of gray cloth will lead to
stretch, relax or fold of gray cloth, so that no sharpest image can be taken. Now that gray cloth tension and convey speed
are related with taking sharp image, so this study attempts to design a gray cloth tension control module, develop the intelligent
online dynamic gray cloth defect automatic detection system. Gray cloth tension control module makes direct regulation of
structural tension of feed and wind rolls and conveys speed control module by load cell coupled with A/D, D/A signal conversion
and two sets of inverters. This study utilized fuzzy control theory to design controller so as to keep surface tension consistency
of gray cloth, improve recognition rate of gray cloth defect, so that the system can have high action efficiency. In previous
fuzzy controller designs, membership functions were often designed by means of trial-and-error method, which usually cost
much time. This study used Taguchi method to make membership function programming, and made main effect analysis to choose
a group of optimal membership function combination. Through systematized, efficient experimental design, tension controller
designed in this study could stabilize gray cloth tension very soon, and acquire sharp gray cloth image. 相似文献

Flexible tubular structures fabricated from solution electrospun fibers are finding increasing use in tissue engineering applications. However it is difficult to control the deposition of fibers due to the chaotic nature of the solution electrospinning jet. By using non-conductive polymer melts instead of polymer solutions the path and collection of the fiber becomes predictable. In this work we demonstrate the melt electrospinning of polycaprolactone in a direct writing mode onto a rotating cylinder. This allows the design and fabrication of tubes using 20 μm diameter fibers with controllable micropatterns and mechanical properties. A key design parameter is the fiber winding angle, where it allows control over scaffold pore morphology (e.g. size, shape, number and porosity). Furthermore, the establishment of a finite element model as a predictive design tool is validated against mechanical testing results of melt electrospun tubes to show that a lesser winding angle provides improved mechanical response to uniaxial tension and compression. In addition, we show that melt electrospun tubes support the growth of three different cell types in vitro and are therefore promising scaffolds for tissue engineering applications. 相似文献

This series of paper addressed the quality control of a vertical-type cross-lapper machine, which is used to produce uniform
layers of fibers with suitable widths and thicknesses. The nonlinear model of the system was derived, and the corresponding
state space representation was obtained. The linearized model based on the equilibrium position of the nonlinear model was
generated, and the associated control property was analyzed. The high order linearized model would be reduced to a verified
lower order model for control system design. The designed traditional and modern controller could make the crosslapper machine
for good card web quality control. 相似文献

This is the first time in the literature dealing with the dynamic modeling and control of a rotating padder roller system.
It is intended to design a control system with effective scheme and robustness to stabilize all vibration modes of a rotating
padder roller system by using one set of sensor and actuator. The controller design depends on the specific pole-zero patterns.
In practice, the pole-zero patterns remain the same, no matter how the physical system parameters are different. By properly
placing the actuator and sensor, a realizable controller and sensor is designed to stabilize all the vibration modes and make
the closed loop system absolutely stable. This will suppress the vibration without suffering from spillover and can eliminate
an infinite number of vibration modes. The performance of this controller has been successfully implemented by computer simulation. 相似文献
