查询词典 Ma

First discarding the thought of fitting by AR model, the ARMA model is fitted by a high order MA model using Gevers-Wouters algorithm on the basis of related functions of ARMA model. Then according to the parameters of the fitted MA model, the ARMA model parameter estimation through solving a system of antipathic linear equations using the least squares method is obtained.

首先摈弃传统的拟合到AR模型的思考方法，而是基于ARMA模型的相关函数用Gevers-Wouters算法对ARMA模型拟合到高阶滑动平均模型；然后在拟合的MA模型参数基础上，用最小二乘算法求解一个不相容的线性方程组，从而估计出ARMA模型参数。

For this reason,the geological records of eucaryotes may be moved up to 2500～2400 Ma from 1800～1700 Ma.

因此有可能将真核生物的地质记录从1800～1700 Ma提前到2500～2400 Ma。

Combined with previous studies, we suggest that the 1100-2200 Ma zircons perhaps originate from the China North Craton, while the zircons of 520 Ma may stem from Jiamusi massif.

根据目前有关年代学研究成果，推断1100~2200 Ma碎屑锆石可能来源于华北克拉通，而样品中的520 Ma的碎屑锆石则可能来源于佳木斯地块。

LC3-FITC had been used to monitor autophagy by immunofluorescence. It showed that there are a high level of LC3 puncta in HCQ+DOX or BAF +DOX treated cells, and in rapamycin treated cells, moderate level in HCQ, BAF, or DOX singly treated cells, and low level in 3-MA+DOX, and there was diffuse fluorescence in untreated or 3-MA treated cells.

内源性LC3免疫荧光染色显示，羟氯喹+阿霉素、BAF+阿霉素及雷帕霉素处理组MM细胞胞浆可见大量颗粒状荧光，羟氯喹、BAF、阿霉素单用组仅有中等量颗粒状荧光，而3-MA及3-MA+阿霉素组胞浆荧光信号基本呈弥散分布，类似于未处理对照组。5。

It puts forward to system compartmentalization , significant functions and design of external interfaces of on-board equipment simulation subsystem by analyzing and research on system structure, functions interfaces of CTCS3 based on SRS of ETCS2.

It realized the function of computing most restrictive speed profiles and dynamic speed profiles, computing on-board odometers, ceiling speed supervision, MA speed supervision, speed comparison intervention, transmitting position report, computing end-point of MA, receiving data by balise etc.

本文通过对CTCS3级系统组成结构、功能、接口的分析和研究，在参照ETCS2级需求规范的基础上，总结出了CTCS3级仿真测试平台中车载仿真子系统的结构划分、主要功能设计、接口设计等，对仿真子系统的软件进行了总体设计，并利用C++ Builder 6.0开发平台实现了CTCS3级车载设备仿真子系统的软件开发，实现了车载设备的主要功能，包括：最严格速度曲线的计算、动态速度曲线的计算、车载里程的计算、顶棚速度监督、MA速度的监督、速度比较干预、发送列车位置报告、计算MA终点，接收应答器报文等功能。

However, animal data also indicate that MA can damage brain serotonin neurones, and it has been suggested that cognitive problems and aggression in MA users might be explained by serotonergic damage.

然而，动物试验的结果也指出，MA可以损害大脑5-羟色胺神经元，有学者提出MA使用者的认知障碍和攻击性可用5-羟色胺能神经元损伤来解释。

As information on the brain serotonin system in human MA users is fragmentary, our objective was to determine whether protein levels of serotonin transporter, a key marker of serotonin neurones, are decreased in brain of chronic MA users.

由于MA使用人群大脑5-羟色胺系统变化的相关信息较少，本研究的目的旨在明确长期使用MA者的脑组织中，5-羟色胺神经元的关键标志物——5-羟色胺转运体的蛋白水平是否降低。

SHRIMP U-Pb concordia ages of the cores of rounded zircons are 620 and 219 Ma, suggesting that the parental magma for the quartz diorite porphyry may have been derived from partial melting of basement materials of the South China block that had been modified by ultrahigh-pressure metamorphism.

具有细微震荡环带岩浆锆石的SHRIMP U-Pb年龄(117.7±1.6 Ma)显示该石英闪长斑岩体的形成时间为早白垩世；浑圆状锆石核部SHRIMP U-Pb谐和年龄为620 Ma和219 Ma，这表明该石英闪长斑岩的母岩浆可能起源于经历了超高压变质作用改造的华南地块基底物质的部分熔融。

These data indicate that Group B zircon grains are captured ones. It is inferred that the Baiceng basic-ultrabasic pluton originated from a mixed melting between an enriched lithospheric mantle and the continental crust rock formed in 409～450 Ma, responding to an extension of lithosphere at 84 Ma or so. This induced the upwelling of asthenospheric mantle.

据此认为84 Ma左右由于华南岩石圈伸展，软流圈地幔上涌，导致岩石圈富集地幔部分熔融，熔体上升过程中与409～450 Ma左右形成的少量地壳岩石发生混染，随后快速侵位冷凝而形成基性_超基性岩墙。

Recording current switchable from 4 mA to 7 mA.

录制电流可从4 mA切换至7 mA。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
