It incorporated the advantages of separately baghouse reverse blow and reverse pulse-jet of air and so on, overcame the low intensity of separately baghouse reverse blow, and simultaneous operating of reverse blow and filtrate at a time.

它集分室反吹和脉冲喷吹等诸类除尘器的优点，克服了分室反吹清灰强度不够，脉冲喷吹清灰和过滤同时进行的特点，因而扩大了袋收尘器的应用范围，提高了收尘效率，延长履带使用寿命。

If the dust cleaning efficiency is known, the geometric parameters of the cleaning system, pulse-jet pressure, time and filtration area of a plenum box (or the diameter, length and numbers of the fiber) will be determined in the pulse-jet baghouse.

若预先确定要求达到的粉尘剥离率，可以通过清灰气流速度方程和剥离力方程确定脉冲清灰系统的几何参数、脉冲喷吹压力、脉冲喷吹时间和分室内的过滤面积（或滤袋直径、滤袋长度和滤袋数量等）。

Oil were recently discovered in brecciated limestone, micrite kimestone and dolomitized limestone associated with Jinding lead-zinc deposits.

兰坪坳陷的油气主要见於金顶矿区的下含矿层，储层主要为上三叠统三合洞组的灰岩和角砾状灰岩石。

Twenty-three isolates of gray leaf spot pathogen, Cercospora zeae-maydis, collected from growing area of Northern China were clustered based on their soluble protein and isozyme profiles obtained through native PAGE in order to base physiologically the pathogen differentiation at protein or isozyme level.

利用聚丙烯酰胺凝胶电泳技术，对采自北方玉米主产区的23个玉米灰斑病菌菌株进行可溶性蛋白质和同工酶电泳图谱分析及聚类分析，从蛋白质和酶学的多态性水平上分析玉米灰斑病菌的生理分化特征。

The biological polymorphism of Cercospora zeae-maydis was studied systematically in the levels of histology, protein and DNA. The major characters in polymorphism of pathogen were listed as follows:(1) The great differences were seen in shapes and sizes of conidiophores, the growth velocity of mycelium and pigment-productivity of colony among pathogen strains. In addition, an albino strain, a kind of mutant, was casually discovered during isolation of pathogen from diseased plants, which supported strongly our previous prediction that there should be some potential genetic variation in Cercospora zeae-maydis.

本研究在组织学、蛋白质和DNA水平上，系统研究了玉米灰斑病菌的生物学多态性，这种多态性主要表现在以下几个方面：①病菌形态学和培养性状多态性：菌株间存在分生孢子形态、菌丝生长速度、菌落产色素能力等方面的差异，该病菌在自然界存在另一种变异类型——白化菌株，说明灰斑病菌的确存在遗传变异的潜能。

The hardware part includes the design of the sensor and the intelligent robot of circumambulate's structure; the software part includes the design of the substrate programme of sensor. The author also has provided the principle of the sub- programme and main- programme, and introduced how to carry out them.

硬件部分设计了灰度传感器的电路，搭建了巡线机器人硬件构架；软件部分包括灰度传感器的底层程序设计，给出了子程序和主程序的设计原理与实现方法。

This paper focuses on designing the intelligent robot of circumambulate by studying the ZiGuang fundamental platform of robot development、Freescale MC9S08GB60 MCU and the intelligent robot of circumambulate. The robot chooses the sensor as the carrier of identify of the path and judge the circuitry by sensor.

本文通过学习紫光智能机器人软件开发平台和机器人主控芯片Freescale 的MC9S08GB60 MCU，以及巡线机器人的基础知识，选择灰度传感器作为路径识别载体，并利用灰度传感器进行线路判别实现机器人的按轨迹自动前进。

The results showed that Cupressus funebris , Cunninghamia lanceolala + Quercus acuissima belonged to the declining populations, whereas, Cupressus funebris + Quercus fabric , Pinus massoniana + Cupressus funebris and Quercus acuissima + Quercus fabric were growing populations, and Symplocos szechumensis + Lindera setchuenensis , Pinus massoniana + Symplocos szechumensis and Pinus massoniana kept stationary.
