So far,the changes of barley anthers inphysiology and biochemistry during the mannitol pretreatmental period and theeffects of mannitol pretreatment on androgenesis and anther culture in barleyhave not been systematically studied.

到目前为止，还没有人系统地研究甘露醇预处理过程中大麦花药所发生的生理生化方面的变化，以及预处理后对大麦雄核发育和培养效果的影响。

The present work was de-signed to study systematically the changes of anther and pollen during themannitol pretreatment period on physiology and biochemistry;and then the ef-fects of mannnitol pretreatment on androgenesis and anther culture were stu-died.The donor plants used in this experiment grow in the field.

所以本文从以上几个问题出发，以大田生长的植株作为供试材料，首次系统地研究了甘露醇预处理过程中大麦花药花粉在生理生化方面所发生的变化；以及甘露醇预处理后对大麦雄核发育和培养效果的影响。

According to either sequence data sets or gene arrangement features at both gene junctions, Brachyuran crabs were monophyletic and divergent between Heterotremata and Thoracotremata. Potamoidea represented by S.

本文基于基因序列和排列数据的系统发生分析都支持短尾类是一单系群；异孔类和胸孔类互为姐妹群；以长江华溪蟹为代表的溪蟹总科与扇蟹总科、梭子蟹总科有较近的亲缘关系。

Aiming at the requirements of the security precaution, the technology of stream media is adopted in the system to ensure real-time transmission and smoothly playing of video stream. In addition, the cyclostyle matching is combined with motion detection to estimate the area and location where the abnormd events are likely to take place, then match these abnormities one by one, and judge the sort about these abnormities at last.

该系统针对安全防范需求，采用流媒体技术，保证了视频流的实时传输和流畅播放，同时采用模板匹配结合运动检测判断出异常情况可能发生的区域和位置，并逐一进行匹配，判断出异常情况的类别。

Chaos is a kind of seeming random, chance or irregular movement, which appears in a definiteness system.

混沌是在确定系统中发生的貌似随机的无规则或不规则的运动。

The problem of buildups jam which easily takes place in the new style dry process rotary kiln was analyzed.

对新型干法窑生产中容易发生的结皮堵塞问题进行了分析，提出了建立预警专家系统解决此问题的思路。

同时，随着城市轨道交通系统运量的不断加大，传统的保护装置越来越不能正确可靠地区分远端短路故障状态与机车起动状态，尤其是当发生远端电弧故障或经大过渡电阻故障时，往往造成保护动作时限加长。

At the same time, along with the increment of cities' railway transportation, it isharder and harder for the traditional protection equipments to distinguish the remote shortcircuit fault or the train starting correctly, especially for the fault with electricity arc ortransition resistance. This always results in the equipment operation time longer that it can'tcut off the short fault rapidly.

同时，随着城市轨道交通系统运量的不断加大，传统的保护装置越来越不能正确可靠地区分远端短路故障状态与机车起动状态，尤其是当发生远端电弧故障或经大过渡电阻故障时，往往造成保护动作时限加长。

Under sunlit greenhouse condition, systematic field and laboratory surveys were carried out to study the effects of different crop successions on main disease development in cucumber.

在温室条件下，通过田间系统观察和室内测定相结合的方法，研究了不同连作年限温室土壤对黄瓜主要病害发生的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
