  1. Serial measurements of serum thyroxine ( t4 ) and thyrotropin ( tsh ) levels were done in 44 newborns locally treated with 10 % pv - i for insertion of percutaneous central venous catheters

    本研究目的觀察在一個高碘攝取城市中不同出生體重與懷孕周數之新生兒在使用含碘溶液后其狀腺功能之變化情形。
  2. The tbc algorithm simulates that wave near the boundaries is plane wave, and its amplitude and direction are decided by trial and error. in this thesis, the operation principle of an awg is introduced and the structure parameters of 8x8 awg with its central wavelength 1550. 12 / 7 / n and channel spacing 3. 2nm are designed by discussing the crosstalk to neighboring waveguide, the insertion losses and losses equal, etc. this thesis employs the waveguide theories to analyze the slab waveguide and the arrayed waveguide, and offers the distributions of stable optical fields

    本文旨在設計一個中心波長為1550 . 12nm 、波長間隔為3 . 2nm的8 8awg波分復用器，通過綜合考慮相鄰波導間的最大串擾、插入損耗、通帶寬度以及各通道損耗均勻等指標來設計、優化awg的各個結構參數，如輸入、輸出波導和波導陣列中相鄰波導的間隔，平板波導的聚焦長度，波導陣列中相鄰波導的長度差等。
