e,anti diamond type lattices .
在专著《Fuzzy Topology》一书中,作者引入了反菱形格的概念,本文在其基础上,进一步指出反菱形格与L-fuzzy 拓扑空间的连通性之间的密切的内在联系,并给出反菱形格的若干条用连通性刻划的等价性质。
6)  diamond mesh
菱形网目
1.
In order to assess the size selectivity for fishes of beam trawl fishing in offshore of the East China Sea,experiments of codends with different mesh configuration,including diamond mesh,square mesh and turned through 90° diamond mesh(T90) in 4 sea trials have been carried out and catch data were collected by comparative fishing method.
为评价东海近海桁拖网渔具对主要鱼类的尺寸选择性,使用对比作业法,在吕四渔场开展了4个航次的、不同网目结构网囊(菱形、方形及横向使用的菱形网目)的选择性试验。
2.
In order to improve size selection for shrimps of multi-codends beam trawls fishing in offshore of the East China Sea,experiments of several sea trials for size selectivity of codends with different mesh configuration, including diamond mesh,square mesh and turned through 90° mesh,have been carried out and catch data were collected by comparative fishing method.
选择性模型对哈氏仿对虾(Parapenaeopsis hardwickii)和葛氏长臂虾(Palaemon gravier)渔获数据的拟合结果显示,选择性模型具有较好的拟合性,但存在航次间差异;不同网目结构网囊的选择性曲线模型都可简化为Logistic曲线;对于哈氏仿对虾,相比菱形网目网囊,方形网目和转向网目网囊的L50较大,而SR较小(菱形和方形网目之间差异显著,菱形和转向网目之间差异不显著);对于葛氏长臂虾,方形网目和转向网目网囊的L50较大(菱形和方形网目之间差异显著,菱形和转向网目之间差异不显著)。
3.
The selectivity of square and diamond mesh codends with different mesh sizes (25mm, 30mm, 35mm, 40mm and 45mm) of two-stick swingnet was analyzed through covernet method selective experiments, in which Logistic curve was regarded as the selection curve and the maximum likelihood method as estimation method of the parameters of selectivity model.
使用套网法作为选择性试验方法,Logistic曲线作为选择性曲线模型,并运用极大似然估计法进行曲线参数估算,对桁杆张网渔具不同网目尺寸(25mm、30mm、35mm、40mm以及45mm网目大小)、不同网目形状(菱形网目和方形网目)的网囊选择性进行分析。
补充资料:火焰喷射器
分子式:
CAS号:

性质:简称喷火器。喷射火焰射流的燃烧武器。最早在第一次世界大战中德国开始使用。是一种近距离火攻武器。主要用于攻击火力点,消灭工事、建筑物、洞穴内的有生力量;抗击冲击的集群步兵。喷火器主要由油瓶、压源装置、输油管、点火装置和喷火枪等部件组成。喷射时,油瓶内的稠化油料在压缩气体或火药等压源作用下,经输油管由喷火枪经油料点火管点燃喷出,形成火焰射流。稠化油料由汽油和铝皂型稠化剂调制而成。喷火器有便携式和车载式两类。便携式重23kg左右。车载式安装在坦克或其他装甲车辆上,携油量200~1500L,射程100~200m。
