查询词典 of the period

A new method of obtaining secondary electron yield and secondary Cs〓 ionization probability by detecting target current and primary ion current under Cs〓 bombardment is put forward The dependence of Cs〓 ionization probability on primary ion energy, primary beam current and substrate compositions, as well as the dependence of secondary ion intensity on erosion time during transient period has been studied The mechanisms of secondary ion emission are explained

二、提出了通过测量靶流和一次束流求取Cs〓轰击下二次电子产额和二次Cs〓离化率的方法，实验研究了一次离子能量、束流强度及不同基体对二次Cs〓离化率的影响和瞬态过程中二次离子强度的变化规律，并对发射机理做了解释。

Biology technique is based on appearance symptom on sweet potato or Ipomoea Setosa after they are infected to identify virus. But it need long period and is apt to be limited by season. Based on coat protein of virus, serology detects virus during peculiar immunolog...

生物学方法是依据病毒侵染后在甘薯或指示植物上的外观症状进行识别，但检测速度慢，易受季节限制；血清学技术是利用病毒外壳蛋白的抗原性，据特异性的抗体抗原免疫学反应检测病毒存在，但制备抗血清需时间长，对含量少和无蛋白外壳的病毒无法检测；分子生物学方法是以核酸为基础，通过检测病毒核酸来证实病毒的存在，该技术具有灵敏度高、特异性强、适应范围广等特点。

Biology technique is based on appearance symptom on sweet potato or Ipomoea Setosa after they are infected to identify virus. But it need long period and is apt to be limited by season. Based on coat protein of virus, serology detects virus during peculiar immunology reaction of antibody and antigen. But it can't detect virus without CP and preparing antibody need more time. The molecular biology method is based on nucleic acid to detect virus. This technique has high sensitivity, strong veracity, wide suitability etc.

生物学方法是依据病毒侵染后在甘薯或指示植物上的外观症状进行识别，但检测速度慢，易受季节限制；血清学技术是利用病毒外壳蛋白的抗原性，据特异性的抗体抗原免疫学反应检测病毒存在，但制备抗血清需时间长，对含量少和无蛋白外壳的病毒无法检测；分子生物学方法是以核酸为基础，通过检测病毒核酸来证实病毒的存在，该技术具有灵敏度高、特异性强、适应范围广等特点。

Using potato tubers of Irish cobbler variety naturally infected with X- and Y-virus, the writer compared the concentrations of X-virus in the young sprouts of different seed pieces longitudinally cut from the same tuber and subjected to various temperatures, light and darkness, normal and dereased oxygen tensions during the period of germination.

在定温箱内所做的发芽温度试验的结果指出，块茎在20℃中发出的幼芽内X-病毒的浓度最高，沉淀滴度一般在1/80—1/160之间，最高的达到1/320，千日红上平均半叶斑点数目约为30.16°及24℃中的病毒浓度相近，沉淀滴度约为20℃的1/2，斑点数目达20℃的2/3左右。28℃发出的幼芽内病毒浓度最低，平均沉淀滴度约在1/10—1/20之间，平均半叶斑点数目为11.9。

This was the period between the Stone Age and the Iron Age.

此一时期介于石器时代与铁器时代之间。

The period in which man learnt to make tools of iron is called the Iron Age.

人类学会制造铁器的时期被称为铁器时代。

Robert had a prim bed-room, and an uncompromising dressing-room allotted to him in the square house, and he woke every morning upon a metallic spring mattress which always gave him the idea of sleeping upon some musical instrument, to see the sun glaring in upon him through the square white blinds, and lighting up the two lacquered urns which adorned the foot of his blue iron bedstead, until they blazed like two tiny brazen lamps of the Roman period.

在那方方正正的大厦里，罗伯特占有了一间整洁的卧室和一间毫不含糊的化妆室；每天早晨他在一个金属弹簧垫子上醒来（这垫子始终给他睡在乐器上的感觉），眼看着太阳透过方方的白色遮帘照射进来，照亮了装饰那蓝色铁床脚的两个红漆小壶，光辉灿烂，活象是古罗马时期的两个小小的黄铜灯。

In late Tang period,influenced by west Asian great cutting Dao,each 'country' is more powerful because of this shape.Because it's hard to find iron and ironstone,a lot of sword was needed to re-smelted.Moreover the former shape didn't reach the new war condition,so it's abandoned and there's little exsited(only inscribed in Tang poems and Tang drawings).

二、在唐末五代十国时期，受中西亚大砍刀的影响，各"国"因为此刀型比原有唐刀更加结实有力，先后装备这种刀型，加上当时各"国"贸易流通受政治影响极大，铁和铁矿石很难买到，故须将大量的刀剑重新回炉炼制此新刀型，加上原有刀型无法适应新的战争条件，导致此刀型被废弃，故现存实物极少（只在唐诗、唐画中有描绘）。

This paper mostly presents the Ironworks' main work achievements in technical and management innovation s in recent years,strengthened moves in independently scientific and technological innovation and deepened enterprise management,further put forward the Ironworks' train of thought in innovation and main points of work for the next period.
