Transgenic bt cotton mainly affect high - instar larvae by retarding the growth and intering the proceeding of ecdysis, pupation, and eclosion. the growth retardation leads to the postponement of growth period duration ( the showed that growth period duration prolonged 17 days ). feeding the larvae with the tissue of the transgenic bt cotton and the moths with the flower of transgenic bt cotton, the number of eggs and hatching rate decreased obverviously
轉基因藥防田中，天敵昆亞群落的個體數占整個昆蟲群落總個體數的10 . 0 % ，其優勢種為蜘蛛類、七星瓢蟲（ coceinellas叩te即uneitatalinnaeus ） 、龜紋瓢蟲（ prol ， laea少只ponjcagoeze ） 、大眼蟬長蜷（ prqp . ylaeajaponicagoeze ）和草嶺（助rys叩asepre即unetatawesmael ） 。 -
The purpose of this paper is to explore the relationships between three methods of feeding ( i. e. pacifier, bottle feeding, and cup feeding ), nipple confusion, and duration of breastfeeding
本文章旨在藉由文獻查證，發展一理論架構，探索三種人工喂養方式，如：奶嘴、奶瓶餵食及杯子餵食與乳頭混淆的關系。 -
Transitional feature of the arc and metal droplet in the welding process with steam shielded arc is investigated by means of analysing the waveforms of welding voltage and current under different welding regimes and it is found that there are two types of arc process behavor ? " arc starting - arc blowing out - short - circuiting " and " arc - starting - short - circuiting ". under the condition of constant diameter of welding wire and its feeding speed, the arc process behavor can be changed by adjusting the inductance of welding circuit as well as the voltage of power supply. if arc process behaves as alternative process of " arc starting - arc blowing out - short - circuiting " with minimum time duration of arc blowing out and maximum frequency of short - circuit transition, the welding process will be stable with less spatter and smooth weld bead
通過分析不同焊接規范下的焊接電壓和電流的波形.研究了水蒸氣保護下電弧及熔滴過渡的特點，發現其電弧過程行為有「燃弧?熄弧?短路」和「燃弧?短路」兩種形式.在焊絲直徑和送絲速度一定的情況下，通過調節焊接迴路中的電感量和電源電壓，可以改變電弧的過程行為形式.若電弧過程呈「燃弧?熄弧?短路」交替進行，並且熄弧時間最短時，短路過渡頻率最高，在這種情況下，飛濺小，焊道成型好，焊接過程穩定 -
Feeding on solanum plants such as tomato, eggplant, and black nightshade, the mean development duration of h. vigintioctopuntata had no significant difference, but there was a significant difference when feeding on pumpkin
結果表明：該蟲在3種茄科植物上各蟲態發育歷期無顯著差異；而在南瓜上存在顯著差異，各蟲態歷期明顯延長。 -
The study found that the prevalence of asthma in hong kong is twice of that in beijing or guangzhou. the study also found that risk factors such as home smoking, maternal smoking during pregnancy, use of synthetic pillow ( foam ), synthetic bedding and use of gas as cooking fuel are closely linked with higher prevalence of asthma. the protective factors are breast feeding ( the longer duration the better ) and early attendance of day care
研究發現本港兒童患哮喘的數字是北京及廣州的兩倍，而一些危險因素，包括家中有成員吸煙、母親懷孕時吸煙、使用合成物質的枕頭和被鋪、及使用氣體燃料煮食，都與較高發病率有密切連系，而一些保護性因素則有母乳哺育（時間越長越好）及較早接受託兒服務。
