分阶段

The sampling cultivations were applied before and after sterilization to compare the effects of the two methods.

第2阶段：入选含氯消毒剂浸泡处理后细菌培养符合国家标准要求的雾化吸入器，再分两组分别采用原包装袋、无菌治疗巾进行保存，两组均在保存1、2、3 d后采样做细菌培养，比较两种方法的保存效果。

The DS4G ion engine utilises a different concept first proposed in 2001 by David Fearn, a pioneer of ion propulsion in the UK, which solves this limitation by performing a two-stage process to decouple the extraction and acceleration of ions using four grids.

DS4G离子引擎应用了与传统离子引擎不同的概念，这个概念是由英国离子推进学的先驱戴维-福恩在2001年提出的。他使用了4个栅格来解决传统离子引擎存在的不足，即分两阶段来减弱离子的吸引和加速度。

条子泥潮盆-潮沟系统的基本地貌结构为分水滩脊和潮沟系统，本文分别对它们的形成与发育、地貌特点及动态变化进行了分析，并探讨了影响其发育的主要因素，即来水条件、来沙条件、空间条件，划定了其主要发育阶段，即形成期、成熟期、衰亡期；在上述分析的基础上确定了潮盆-潮沟系统的主要功能，即通过潮沟系统渲泄落潮后期滞留在其潮盆范围内的滩面薄层水、通过潮沟系向潮盆内部输入或输出泥沙、限制涨落潮动力主。。。

In cooperation with the serial NSPO sounding rocket programs and application of the research results of the Institute of Aeronautics and Astronautics, National Cheng Kung University in the current proposal, we propose a series of Indigenous Propulsion Experiment payload Onboard Sounding Rockets, including: hydrazine monopropellant, hydrogen peroxide monopropellant, micro-propulsion and bipropellant subsystem. In the first stage of this multiple-year project, in two years (2005/4/1~2006/12/31) with two phases (phase I: 2005/1/1~2005/6/30 and phase II: 2005/7/1~2006/12/31) we will be compliant with the NSPO sounding rocket launch schedule of 2006 and develop the hydrazine thruster system onboard the sounding rocket as the payload to verify the key techniques and the thruster system developed.

本计画第一阶段预计以两年时间(民国94年4月1日起至95年12月31日止)分两期(第一期自民国94年4月1日起至94年9月30日止，第二期自民国94年10月1日起至民国95年12月31日止)配合NSPO的民国95年的探空火箭发射规划时程，发展联胺单基推进器系统做为探空火箭酬载，除了验证自主发展的推进器系统与关键技术外，并进行高空实验以进一步模拟测试该系统在高空环境与微重力状态的性能特性。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
