We found 110 Kentish Plover nests in 8 sites, total area 22.74 ha, in Shengshi, Changhua during mid-April to mid-May. The hatching success of 89.09% was high compared to other studies. Thirty-six experimental artificial nests were set for a two weeks period in May to examine the effects of predators and rainfall. Among the 12 unsuccessful nests, 6 were flooded, 4 were abandoned, and 2 were predated. Successful nests and unsuccessful nests showed no difference in distance to nearest road and distance to nearest vegetation line.

调查从四月中旬至五月中旬於样区共追踪110巢东方环颈鴴的孵化情形，并於五月份设置36个人工试验巢进行两星期的追踪以了解捕食和降雨对孵化成功率的影响程度。110巢东方环颈中有98巢成功孵化，孵化成功率高达89.09%，以Mayfield Method 估算之孵化成功率亦高达83.53%，未孵化的12巢中，有6巢是因降雨淹水而失败，4巢是亲鸟弃巢，2巢被捕食。

The new technique reduced the distance ladder to three "rungs":(1) The distance to galaxy NGC4258 is measured using straightforward geometry and Kepler's laws;(2)Cepheids in six more distant galaxies are used to calibrate the luminosity of Type Ia supernovae;(3) The Hubble constant is measured by observing a brighter milepost marker, Type Ia supernovae, in more distant galaxies hundreds of millions of light-years away, embedded in the expanding universe.

这种新技巧简化了距离跳跃为三个"阶梯"：1、星系NGC 4258的距离采用开普勒定律和简单直接的几何方法精确测量；2、在6个更远的星系中的造父变星用来校准Ia超新星的光度；3、深嵌于数亿光年外的膨胀宇宙中的星系中的Ia超新星——一种遥远而明亮的量天尺，被用于精确测定哈勃常数。

Because it uses the object to show fabricated instrument,so we can finish the experiment by landing the distance education net.
