The Citrus leaf miner (Phyllocnistis citrella Stainton) is one of the major citrus pests in South China and other parts of the world. No detailed description of the morphology of the larval stages of this species has been published, although descriptions on other species in this genus has appeared in literature and Ba-Angood(1977) based on the length of the mine determined that there are 4 instars in this insect . He didn't described th difference of all instars.Through a series of observations, The authors have found that the larval development consists of 3 moults, and the head capsule of the moulting larva can be found in the mine formed by the larvae. There are 4 instars, the first.,second and third instars are actively feeding stages, the fourth instar ceases feeding, and spins and forms cocoons. The length of the mine varies considerably according to the larval stages from 7-169 mm. The head capsule of the first, second, third and fourth instars 0.12, 0,20, 0.34 and 0.32mm , respectively . Except the fourth instar (unfeeding stage) the head capsule of the leaf-mine grows in geometrical progression, when the number of the instar is plotted a-gainst the logarithm of the head measurement of this insect, a straight line is obtained. The observation fits the Dyar's law.In this paper, the morphology of different larval stages is described, illustrated by 15 figures and 2 tables . The relation between the morphology and feeding habit is also discussed.

柑桔潜叶蛾(Phyllocnistis citrella Stainton)属鳞翅目、叶潜蛾科(Phyllocnistidae),以幼虫潜叶为害,是柑桔新梢的主要害虫。 关于该虫的龄期,一直未有报道。仅Ba-Angood(1977),根据隧道和粪便大小判断为四龄,不是经蜕皮壳来鉴别。作者根据蜕皮壳将幼虫分为四龄,蜕皮壳在隧道中可找到。1~3龄取食为害,4龄幼虫停止取食,专司吐丝结茧,建造蛹室。 一龄幼虫头宽0.12毫米,体长0.34~1.03毫米,头胸部显得特别膨大,腹部仅及体长之半,第10腹节不分叉。 二龄幼虫头宽0.20毫米,体长0.77~1.771毫米,体扁平,每节背面的四个凹孔可见,第10腹节己分叉。 三龄幼虫头宽0.34毫米,体长1.5~5.5毫米,体背中线两侧扁平,背中线弧形隆起,尾端尖细,第10腹节分叉的两裂叶延长,后期幼虫具一对较长的尾状物。 四龄幼虫头宽0.32毫米,体长3.23~4.2毫米,体长筒形,口器特化为吐丝器,第8~10腹节逐渐收窄,呈喇叭状。 各龄幼虫的潜道长短及粪便大小,亦可粗略地作为龄期的区分,但以头宽区分较为准确。幼虫头宽的增长(除不取食的四龄幼虫头壳外),成几何级数...

Most of man made communication signals are cyclostationary. Because the blind beamforming algorithms using cylcostationary signal properties are the genuine blind algorithms, they attract much attention. R CAB algorithm is one of these algorithms. However, the matrix inversion process in CAB leads to the complicated computation. Beamforming is a kind of multidimensional signal processing problems. With the increase of the array sensors, the burdens of computation rise faster. A new blind beamformer with improved Hopfield network and the corresponding circuit are presented. With the parallel structure of neural network, it not only avoids the computation of the matrix inversion, but also makes easy to work in real time. Because the diagonal loading technique is employed, the converging speed is faster and the performance is robust. Simulations demonstrate that the proposed approaches have the better performance and can be easily realized by circuits.

绝大多数通讯信号都具有周期平稳信号特性。利用信号的周期平稳特性可以进行真正的盲自适应波束形成,因而受到了广泛关注。鲁棒CAB(R-CAB)算法就是其中的一种,但其中涉及矩阵求逆,运算量很大。波束形成属于多维信号处理问题,阵列中阵元数的增加导致运算量成几何级数增加。文中提出了一种盲神经网络波束形成算法。由于神经网络具有网状计算结构的特点,故该方法不仅避免了矩阵求逆运算,同时更便于实时实现。该方法还利用对角加载技术,从而加快了收敛速度,保证了算法的鲁棒性。仿真实验表明其性能优越,易于电路实现
