Are thermal stressed samples prepared for microsection coupon per IPC-TM-650, Method 2.6.8 and microsectioned per IPC-TM-650, Method 2.1.1.2 with acceptability verified per IPC-6012, Class 2?

是否根据IPC-TM-650 2.6.8方法对热应力取样并根据IPC-TM-650，2.1.1.2方法取切片样品并依IPC-6012.2级水准对其接受标准进行判定？

For example, read-write channel of a disk drive systems, communication systems, microwave telescope array, and 10-GSamples/s microwave receiver are the cases.

举例而言，硬碟驱动系统的读写，通讯系统，微波电子天文望远镜，以及每秒十亿取样的微波接收器，都属於此应用范围。

This study was carried out in collective-owned summer grassland in Ganchaitan, which is located at the south foot of eastern Lenglongling Mountain (a branch of north Qilian Mountain), with yak and Tibetan sheep miscellaneously grazed on it. The grassland type could be classified as alpine meadow, dominated by Potentilla froticosa shrub. This study, under grads grazing stress, focused on the community structure, composition, species diversity, above-ground biomass of PFS, by using pane net sampling based on spatial distribution in stead of temporal succession. Results showed that: Grazing stress negatively related to the distance between grazing area and resident area.

以祁连山北支冷龙岭东段南麓的甘柴滩夏季牧场集体长期混合放牧的高寒金露梅Potentilla froticosa灌丛草场为对象，利用空间分布代替时间演替的方法，采用方格网法取样分析调查，对不同放牧压力梯度下金露梅灌丛群落的结构、组成、物种多样性、地上生物量进行研究，结果表明：①放牧居住点由远到近，放牧压力梯度不断增加，金露梅株高、密度、覆盖度、地上生物量和丛间草地的地上生物量均有不同程度的降低，地上的总生物量降低幅度达84.77%。

From March 2001 to January 2002, the stereotyped behavior of Moschus sifanicus was studied in a deer farm of Xinglong Mountain Nature Reserve.

于2001年3月—2002年1月，采用焦点取样法对甘肃兴隆山自然保护区麝场圈养马麝的刻板行为进行了研究。

The sample, at the instant of the low-to-high transition of QS, appears with a negative sign at capacitor C 2 and subsequently at the output.

在 QS 低－高的转换的瞬间的取样和一个负信号一起出现在电容器 C 2和后来的输出里面。

In order to investigate the tempo-spatial characteristics of negative air ions distribution in Guangzhou from September to November of 2008, we choosed typical plot to make scientific researches, which including the monthly variation of air negative ions, the influences of types of functional zones, sampling timeinterval and typical habitat on air negative charge ion concentration.

为研究广州市下半年空气负离子分布的时空特征，利用空气离子测量仪，在广州市选择典型的采集地，分析了广州下半年空气负离子的月际变化以及功能区类型、取样时段、典型环境对空气负离子浓度的影响。

It also acquires the lower and upper approximation regions of all clustering kernels based on rough set theory,and achieves the explicit object-dividing method by means of their neighborhood system.

依据对象聚类邻域确定聚类数量和聚类核，以及对象的粗糙近似划分，使得聚类具有密度自适应和孤点不敏感的特点，取样分析有效提高了算法效率。
