In view of the cooling difficulty in complex injection mold, the difference between conventional cooling channels and Conformal Cooling Channels (CCC) is researched. CCC is superior to conventional cooling channels on cooling effect according to the simulation analysis of plastic flow based on Autodesk Moldflow Insight software. Considered the manufacturing difficulty of CCC, an approach which uses three-dimensional printing and investment casting is put forward in the end.

In order to safeguard China's increasingly important sovereignty as well as our maritime rights and interests, monitoring of waters has been given more and more important importance. On such an occasion, electronic sensor and optical sensor appear as two applicable and useful means among all those space borne sensors which are widely used by many countries and regions thanks to their distinctive edges. In this paper, the key technology of target association and its pragmatic application prospect are further studied on the basis of the existing knowledge of electronic sensor and optical sensor.
The amount and diversity of phytoplankton, zooplankton and benthos are very essential indexes for the marine ecology. These indexes are meaningful guidance for the regional management, sustainable development and ecol...

Based on the characteristics of weather modification in Yunnan Province, this paper proposed a weather modification operation model which aims to help operating managers with operating scenario and provide operating spots, fixed or mobile, with detailed intelligent decision-making information, including: operating spot, fire elevation, azimuth, amount of ammunition. The data that this model utilizes is from the conventional sounding materials, XDR radar and DPL radar together with the historical applications and actual usage.

This paper mainly studied the effect of niobium on graphite which was quantitatively analyzed by the image analysis software. The results showed that with the amount of niobium increasing the number of nodular graphite and the percent of spheroidization in ductile iron were reduced whereas the size of nodular graphite was increased.
The fluid noise of rotor oil pump is studied in this paper, and the turbulent and flow sound field model of rotor oil pump are built. Based on CFD software, three dimensional unsteady internal flow field numerical sim...
