Currently, more and more chinese citizens enjoy to “ home gardon ” in their apartments. they usually pour their plant by “ tap water ”. we know that it would be better for the growth of plant if we pour them by “ rain water ” or “ river water ” instead of “ tap water ”, but many of chinese citizens living in apartments are not able to collect and store enough “ rain water ” in the days of rain cause their limited living space. therefore i offer those businessmen who selling “ soil of gardon ” can also collect and store “ rain water ” and “ snow water ” in the special weather days and sell them to the families of enjoying gardon in apartments. this sort of commercial action would be low cost. that would solve the health problems of plant cause poured “ tap water ” and bring benefits to businessmen. the most important thing is : if this commercial action would have developed for a long time so that it could be practiced all over chinese cities, our country would save large quantity of “ tap water ” every year
當今的城市中,綠色植物已經成為家居美化中必不可少的因素,隨著人們越來越崇尚「
熱愛綠色、回歸自然」的生活方式,家庭園藝將會被更多的家庭所
熱衷,粗通園藝的人都知道,用雨水、河水
澆花遠勝于自來水,可是由於時間和居住條件所限,城市居民很難在下雨的時候收集足夠的雨水儲存起來用於家庭園藝,建議售賣園藝土等園藝用品的市場商戶,能在雨雪天收集大量的雨水、雪水儲存起來,賣給
熱愛養花的家庭,價廉物美,一方面可解決公寓樓中中長期用自來水
澆花帶來的不良問題,一方面給自己帶來些收益,最重要的是: 「涓涓細流,匯成江河」 ,如果這種設想能發展成長期的商業行為,並在各大城市都實行起來,那每年能節約多少自來水呀!

For the purpost of thin and even wall thickness distribution, and mass production dialy, the molds for food packaging materials, such as pudding cup, airline cup, jelly cup, closeure, pet preform. . etc., have to be designed combining precision and hardness with hot runnet system in structure
許多食品包裝器皿,如布丁杯、航空杯、果凍杯,瓶蓋、 pet瓶瓶胚等,由於其成品對于厚度及均勻度之要求相當嚴格,同時每日需生產龐大數量,因此其模具在結構上必須要求具有精密度高、硬度大、使用
熱澆道系統等設計方可達到目的。
