前翅

Either of the leathery or chitinous forewings of a beetle or a related insect,serving to encase the thin,membranous hind wings used in flight .

鞘翅甲虫或其它相关的昆虫的一对坚韧的或几丁质的前翅，用于保护飞行中薄的、膜状的后翅

The results show that the camber deformation may play an important role in lift and drag coefficients. The positive camber deformation of the hindwing during the downstroke generates the vertical force, whereas negative camber deformation of the wing during upstroke generates thrust force. The freely flying dragonfly's hindwings play an important role in providing a stable lift force, and the forewings are very important for controlling flight behavior, such as turning, climbing and so on.

建立了自由飞行昆虫运动测量系统，开发了结合条纹投影和昆虫翅膀特征点测量翅膀变形和身体姿态的方法，首次测到了自由飞行昆虫运动翅膀变形和各种相关角度，速度、加速度，身体位置与姿态，通过分析比较直飞和转弯各个运动参数，认为蜻蜓的飞行控制主要由前翅完成，而后翅主要用于产生升力。

For comparison reason, the planar and spatial models based on a forewing structure were analysed, it is shown that the cambered corrugation in the wings can improve the flexural stiffness of dragonfly wings effectively; the veins distribution and their size variation in different zones are quite reasonable.

对前翅平面模型和立体模型的静力性能进行了对比分析，发现翅膀中的起拱、起皱结构可显著提高蜻蜒翅膀的弯曲刚度；分布在翅膀不同区域的翅脉横截面尺寸与其受力大小是完全相适应的。对翅膀模型分有膜、无膜两种情况进行对比分析，得出翅膜中产生的膜应力刚化效应可有效改善翅膀结构的刚度。

Both of them harbour a large proportion of diurnal species that exhibit conspicuous colouration on the elongated forewing and reduced hindwing and the annular black-yellow abdomen plus the chemical defence employing plant alkaloids is often considered to be relevant

此两族昆虫都包含大量日行性物种，且在外型上具有显眼的色彩、较长前翅、退化的后翅以及黑、黄相间的腹部环纹，再加上以植物碱作为二次代谢物的防御机制，因此它们常被认为具有拟蜂现象(wasp-mimicry)。

该目昆虫的前翅发展成坚硬的鞘翅或壳。

Lepidopterainsectsincluded11families,morethan 30 species of moths,such as Noctuidae(relative number percentage of Lepidopterainsects36.6%),Sphingidae(24.1%),Geometridae(13.4%)and Limacodidae(9.5%). Thelength of forewings ranged from 5—40mm(99.5%) and 60—65mm(0.5%). The result ofPearson correlation analysis showed that foraging of Rhinolophus ferrumequinum might beselective, not random. 2. Foraging tactics mostly included two ways: aerial hawking during the period of thepeak of insects activity and flycatching during the insects' non-peak activity period.

马铁菊头蝠所捕食的鳞翅目昆虫包括 11 科 30余种蛾，主要以夜蛾科Noctuidae(占所捕食的鳞翅目昆虫的数量百分比为36.6%)、天蛾科Sphingidae(24.1%)、尺蛾科Geometridae(13.4%)和刺蛾科Limacodidae(9.5%)为主，捕食的鳞翅目昆虫前翅翅长介于 5—40mm(数量百分比为 99.5%)之间和 60—65mm 之间(0.5%) Pearson 相关分析表明马铁菊头蝠在捕食过程中不是随机捕食，而。

Its forewings and hindwings have a distinct pattern of black and yellow and it flies like a butterfly.

它们的前翅和后翅布满鲜艳的黑黄色图案，飞行时就像蝴蝶般翩翩起舞。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
