In the retrofocus project, a retrofocus structure with two elements is used in the object lens to enlarge fov and back working distance, in the head of which the negative meniscus have the effect of balancing aberration and deviating rays like a prism. and a standard hyperhemisphere immersion lens with high refractive index is put behind the object lens to satisfy the receiving of a detector with smaller photosensitive
反遠距設計方案中物鏡採用二片式反遠距結構，增大了視場和后工作距離，彎月型負透鏡在前，具有平衡像差和棱鏡的偏向作用;物鏡後放置高折射率標準超半球型浸沒透鏡，滿足小光敏面探測器接收。The magnification of any telescope can be changed very easily by changing the eyepiece. even for the largest telescopes, the magnification is seldom over 500, usually between 100 - 200. thus, large telescopes do not magnify more, they only show brighter and sharper images
其實大望遠鏡並不是把天體放得更大，而只是提供一個較光和較清晰的影像罷了倍率是物體視大小的放大比率，例如一個原本視角直徑為1角秒的物體，若放大后的視大小為30角秒，那麼倍率便是30倍。The structure of fertilizers was studied by scaning electronic microscopy ( sem ), and the nutrient release characteristics were studied using water dissolution rate method and soil column leaching method. [ result ] the 24 hours n water dissolution rates of sapcus were 18. 22 % - 83. 87 %, and n accumulated leaching rates in four weeks were 40. 91 % - 65. 38 %, which decreased by 5. 21 % - 40. 68 % compared with that of urea under the same experiment conditions
方法以不同類型和吸水倍率的高吸水性樹脂為包膜材料，以大顆粒尿素和改性礦物包膜尿素為原料肥料，研製出高吸水性樹脂單層包膜尿素、高吸水性樹脂復式包膜尿素系列產品，利用電子掃描電鏡研究了其結構特徵，並以水中溶出率法和模擬土柱淋溶法研究其養分釋放特性。
