The control of the whole test-bed is completed by a Programmable Logic Controller. The place of seeds are tracked by the sensor, it can obtain position of any seeds fleetly and exactly. The open or close of high-pressure airflow is controlled by the magnetic valve, which blow the seeds into the container according its grade information .The software for the communication from PC to PLC was compiled , which was based on Visual C++, it was proved to be effective and friendly to operation .

本研究选择可编程控制器PLC来实现对整个试验台的控制，由色标传感器对种子位置进行实时跟踪，快速、准确地获得运动中每一粒种子的位置信息，通过电磁阀控制高压气流的通断，将种子按其级别信息吹入相应的容器里，研究还包括PC机与可编程控制器PLC之间的通讯功能的实现。

Based on the previous experiments, we choose CNTs/CdS core-shell nanowires as inorganic materials and poly(benzyl-ether) dendrons with thiol functionalities as organic solubilizer. The solubility of CNTs/CdS core-shell nanowires in normal solvents was expected to improve through chemical interactions between core-shell nanowires and solubilizer. The enhanced solubility can improve facility in processability. It also provides a new application method in nanomaterials.

本论文在课题组原有工作的基础上，以制备可溶、易加工的有机-无机复合纳米材料为应用目标，选择具有自己课题组研究特色的CNTs/CdS核壳纳米线结构作为无机材料，选择带巯基的聚苯甲醚树枝状分子作为有机增溶剂，通过带巯基的聚苯甲醚树枝状分子对CNTs/CdS核壳纳米线的化学作用，改善了核壳纳米线在常用有机溶剂中的溶解性能，为材料的湿法加工提供了基础，也为类似纳米材料的应用开拓了一种新的方法。

Is a special desiccant desiccant specializes in the production of enterprises, enterprises in line with the quality first, credibility first business philosophy has been developed by leaps and bounds, the customer won a good reputation, customers demand that we the driving force, the requirements of customers is our direction, the company's main silica gel desiccant, expansive soil desiccant, molecular sieve desiccant, desiccant minerals, fiber desiccants, packaging materials may be in accordance with the request of the customer choice, have the filter paper, non-woven cloth, composite paper, reticulate paper, Tyvek°the United States for the production of 1 ~ 10000g customers a variety of packaging is widely used in electronics, electrical appliances, machinery, hardware, medicine, food, leather, shoes, hats, toys, furniture and other industries.
