Our flocks and herds, if it were not for the protection we get from insect-eating animals.

昆虫就将会使我们无法在这个世界上居住；如果我们没有受到以昆虫为食的动物的保护，昆虫就会吞嚼掉我们所有的庄

We have developed many kinds of optical methods to measure the insect flight. For example, a beating force measurement method reduces the uncertainty caused by air turbulence; a flow measurement using a frame straddling technique decreases the interval between exposures of the flow;extracting the weak distorted fringes on the dragonfly wing by a correlation algorithm; measuring the camber deformation of a dragonfly wing using projected comb fringe without hypothesizing that the wing is a rigid plate. By measuring the beating force, wing kinematics and flow, simutantously, we can analyze the relationship among many flight parameters.

本研究针对昆虫运动的特点，研究开发了测量昆虫运动，特别是自由飞行昆虫运动的光学方法，包括：风洞中扇翅力的测量，解决高灵敏度光学测量的抗干扰问题；帧头帧尾流场测量方法，解决由CCD拍摄帧频导致的测量速度低的问题；调制相关算法，解决透明翅膀上散射光较弱问题；梳状条纹投影法，解决翅膀弓形变形测量问题，不需要以往的翅膀刚性平板或刚性条杆假设；多参数的综合测量，解决各参数间的相位匹配问题。

From the flower spider with its lethal arms, the little bee that lives in a snail shell, the birth of a butterfly and the cuckoo fly to the terrifying adventures of the praying mantis, we are taken down to ground level to partake in the rhythm of their hectic lives with mind-blowing images full of fun and surprises.

今集《昆虫世界》会为大家介绍西欧另外二十多种昆虫，揭开它们留连花丛的一些不寻常现象。在昆虫世界里，喜欢采花蜜的不独是蜜蜂的专利，一些狠毒的蜘蛛也喜欢吃甜头，靠花蜜而活。相反，那些仰赖花粉的蜜蜂，它们的安乐窝不选址在花丛间，反而要住在蜗牛的硬壳中。何解？还有一只蝴蝶的诞生，以及杜鹃鸟冒险闯进螳螂巢穴的情景…等，都会色彩夺目地呈露在观众眼前。

Infection by baculoviruses not always results in insect death, and persistent baculoviruses are popular haboured in insect populations. Moreover, the persistent infection can be transformed to a replicative and infective state caused by stress factors, which can cause epizootics in outbreak populations.

杆状病毒感染昆虫宿主并不一定导致昆虫死亡，其持续感染在昆虫种群中普遍存在，且在某些刺激条件下，持续感染可被激活为增殖性感染并引发病毒流行病爆发。

Most of insects usually don not have the hemcoyte for transporting oxygen, the respiratory of insect is chiefly accomplished by the tracheal system that spreads all over the whole body. Outside oxygen enters the tracheal system through spiracles arranged in two sides of body and is transported through trachea and tracheoles to meet directly the needs of tissues.

一般认为大多数昆虫体内没有运输氧的血细胞存在，昆虫呼吸主要是靠遍布全身的气管系统来完成，O2靠扩散作用由分布于昆虫身体两侧的气门处进入，经气管、微气管的运输而直接给组织供氧。

The insects were surveyed in 100 m×100 m quadrats and caught by sampling frame and net-trap methods. The insects number was recorded and samples were collected for indoor identification.

昆虫的调查采用100m×100m的样方，利用样筐和网捕法收集昆虫，记录昆虫数量，采集标本在室内进行鉴定。

Asian citrus psyllids and in the Citrus Aphis citricola both the phloem feeding insects, but insect feeding behavior of two significant differences, in addition to two kinds of insects share a common EPG wave (A wave, B wave, C wave, E1 wave, E2 wave, G wave), the wave of Aphis citricola appeared in the path of many pd wave, pd wave is aphids in plant cells in the epidermis during exploratory puncture the cell membrane caused by feeding, which kind of contact information on the intracellular selection in the aphid host plant play an important role in the process.

求中文翻英文翻译，很急，谢谢亚洲柑桔木虱和绣线菊蚜在沙田柚上都为韧皮部取食性昆虫，然而，两种昆虫的取食行为有明显差异，除了两种昆虫拥有共同的EPG波形（A波、B波、C波、E1波、E2波、G波）外，绣线菊蚜在路径波中出现很多pd波，pd 波是蚜虫在植物表皮层细胞的试探性取食时刺破细胞膜而产生的，这种对胞内信息的接触在蚜虫选择宿主植物的过程中起了重要作用。

This paper summarizes the general properties of mitochondrial ribosomal RNA,transfer RNA,protein coding genes and noncoding regions,and the phylogenetic usefulness of individual mitochondrial genes for insect taxa.

通过对昆虫遗传物质的研究，探讨不同分类水平上的昆虫类群之间的系统发育、进化机制和种群遗传变异及分化，从生命的本质上探寻昆虫各类群之间的系统关系[1，2 ] 。

Insects would make it impossible f or us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the prot ection we get from insect-eating anim als.

昆虫就将会使我们无法在这个世界上居住；如果我们没有受到以昆虫为食的动物的保护，昆虫就会吞嚼掉我们所有的庄稼并杀死我们饲养的禽兽。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
