From 1953 to 1955 the wheat mite was under observation in Yahan. It was found tohave three complete overlapping generations per year.

麦圆蜘蛛为小麦的严重害虫之一，自1953一1955年，我俩在雅安前西康省农业拭阶站曾对它进行过一些研究工作。

This devise is a pair of reformed chopsticks,which could economize efforts and adds more efficiency through the ribs shape of design at the botton to have more contact faces and points between chopsticks and foodstuffs. It is easy to clip tiny or slippery foodstuffs just like noodles, beans or eggs. On the other hand, this reformed chopsticks is more convenient than the traditional one which is in a pole shape or have concaves on it. The reformed one need not adjust the concave side to cilp foodstuffs.

本创作是一种更省力且使用更方便的改良快子，藉由筷子夹持端之肋条状设计，增加筷子与食物间之接触面积与接触点，对於夹取面条、豆类或卤蛋等外径、体积细小或表面圆滑之食物甚为方便有效，相较於传统圆杆状或表面设有内凹沟槽之筷子，本筷子不仅夹持力更佳，使用时更不需刻意调整设有内凹沟槽之部位来夹持食物，使用上更为方便省力。

Methods: To analyze and compare the shape and diameter of foramina ovale on 205 adult CT images on base of skull(410 sides) with those of and 78 adults' basalis samples(156 sides).

目的：通过对颅底CT和颅底标本进行对照研究，观测国人卵圆孔的形态，测量其径值，为临床射频温控热凝术治疗三叉神经痛提供依据。

In this study, we developed a double primer PCR method and female-specific FISH probes which could solve these two questions, respectively. The major results are as follows:1. Analysis of female half-smooth tongue sole genomeGenome sizes of C. semilaevis, Paralichthys olivaceus, Kareius bicoloratus and Verasper variegates were estimated via flow cytometry method and compared. The male and female C.
