It was caused that the absorption characteristics of the absorber were improved. The conduction loss and magnetic loss were expected to be occurred together because two matching frequencies were shown with carbon addition. It was confirmed that the matching frequency of the microwave absorber could be controlled by controlling heat-treatment temperatures and carbon additions.ons.tions.Ê¥îÜ)À¸·Î µÇ°Å³ª °ú°¡È²(ΦʥüÜ)ÀÌ µÉ ¿ì·Á°¡ ÀÖ´Â Á¦Á¶°øÁ¤(ð²ðãÍïïï)¿¡¼´Â ÈçÈ÷µé ÀÌ ¹æ¹ý(Û°Ûö)À» ¹«½Ã(ÙíãÊ)Çϰí ÀÖ´Ù. ¿©±â¼ °Á¶(Ëðà)ÇØ µÎ¾î¾ß ÇÒ °ÍÀº Ç×»ó Á¦Ç°(ð²ù¡)ÀÇ ¿ÜºÎ(èâÝ»)¸¦ ¿ÏÀü(èÇîï)È÷ °¡È²(Ê¥üÜ)½Ãų ÇÊ¿ä(ù±é©)´Â ¾ø´Ù´Â °ÍÀÌ´Ù. ´Ù°ø¼º(ÒýÍîàõ)À̳ª ±âÆ÷»ý¼º(ѨøÜßæà÷)À» Á¶Àå(ð¾íþ)ÇÏ´Â ºÒ·®°¡È²»óÅÂ(ÜôÕÞÊ¥üÜßÒ÷¾)¿Í Ç¥¸é(øúØü)¿¡¼ÀÇ °ú°¡È²»óŰ£(ΦʥüÜßÒ÷¾Êà)ÀÇ ±ÕÇü(гû¬)À» Ãë(ö¢)ÇØ Áà¾ß Çϴµ¥ ¹°·Ð(Ú¨ÒÕ) À̶§´Â °¡È²½Ã°£(Ê¥üÜãÁÊà)À» ´ÜÃà(Óõê)½ÃÄÑ¾ß ÇÑ´Ù´Â °æÁ¦Àû(ÌèðîÜ)ÀÎ Ãø¸é(ö°Øü)µµ ¾Æ¿ï·¯ °í·Á(ÍÅÕç)ÇØ¾ß ÇÑ´Ù.

| A new circulating hydroponic system was invented for oriental melons grown in the greenhouse. For developing nutrient solution management techniques, we examined the changes of nutrient contents of circulating solution in three different types of new hydroponic systems. The yield and fruit quality of oriental melons in Hydroponics were better than those in soil culture. The substrate culture was appropriate fer hydroponics of oriental melons, and NFT was turned to be the opposite due to the physiological disorder during hot seasons. Yamazaki's melon solution with EC 2.0dS.m$^{[-10]}$ was the most appropriate for oriental melons. The new circulating hydroponic system seemed to be appropriate for oriental melons because of the stable EC, pH and the macro- and micro-element contents. NO$_3$-N, Ca and Mg contents in the circulating solution kept a good balance in all types of hydroponics. However, p content, compared to other types, decreased by the degree of 1 me.L$^{[-10]}$ in perlite medium. K content showed irregular status in perlite but showed the stable status in cocopeat. Generally, microelements, except Mo, showed stable absorption in the substrate culture. However, in NET, most of the elements showed irregular absorption except B and Mn. Microelement absorption, especially Cu, Zn and Mo, decreased during hot seasons. |
