Mafic intrusive rocks in Wuqiagou area, eastern part of Ahai Orogenic belt, include diorite porphyrite, olivine gabbro cumulates, and hornblende gabbro cumulates. 阿尔泰造山带东段的乌恰沟地区发育大量镁铁质侵入岩(岩脉或小岩体),包括闪长玢岩和具堆积结构的角闪辉长岩和橄榄辉长岩。
DOA estimation method of coherent signal based on fourth-order cumulates 基于四阶累积量相关信号的DOA估计
The rocks are mainly cumulates. 岩石主要是堆晶岩。
There are many kinds of adaptive filter algorithm based on second-order cumulates according to different optimization rules. 根据优化准则的不同,基于二阶累积量的自适应滤波算法又分为很多种,最常见的是最小均方误差(LMS)算法和最小二乘(RLS)算法。
The flow calculator transfers the flow rate, pressure, temperature analogue signal to digital, then calculates the real time flow in standard condition and cumulates the flow. The real time flow, cumulate flow, history flow, pressure and temperature are displayed on the LCD. 流量积算仪采集4~20mA的流速、压力和温度信号,计算出实时的标准状况流量,然后对流量进行累积计算,通过液晶显示屏显示实时流量、累积流量、温度、压力以及历史流量。
In respect of mineralogy and petrology as well as strontium isotope, the Pl-lherzolite exhibits some features of transition from the cumulates to the mantle peridotite. 在矿物成分、化学成分及锶同位素等力面,含长二辉橄榄岩具有介于地幔橄榄岩和堆晶岩之间的某些过渡特征。
The Pl-lherzolite differs from the cumulates in having blastic texture and high-temperature deformed fabric of Ng [ 100] characteristic of the mantle peridotite and yielding orthopyroxene. 含长二辉橄榄岩以其具有地幔橄榄岩特有的变晶结构和Ng(100)高温变形组构,以及含斜方辉石等特点而区别于堆晶岩。
There is a threshold of change for fatigue damage of rock, and, only when local strain of fatigue damage cumulates and achieves the above-mentioned threshold, the fatigue crack will come into being and expend; 岩石的疲劳破坏存在门槛值,只有在局部应变或损伤疲劳累积达到疲劳裂纹扩展门槛时,疲劳裂纹才会形成和扩展;
Then, blind source separation ( BSS) was applied to extract independent components from the extended observation vector, according to principle of maximizing statistical independence between estimated components, which was formulated by cumulates higher than second-order. 依据最大化估计分量间独立性的准则(由高阶累积量构成)对多维观测实施盲源分离。
Texture, major and trace element compositions suggest that the Yangyuan pyroxenites represent magmatic cumulates at high pressure. 岩石结构和主微量元素组成说明阳原辉石岩是高压堆晶体。
