查询词典 biased sample

Due to forward-bias-induced annealing effects,the laser diode biased during irradiation is less degraded than that short-circuited,and annealing curves can be fitted sectionally with different annealing rates.

激光二极管辐射损伤存在着正向偏置退火效应，FP和DFB结构的二极管具有相似的加电退火规律，均可拟合成指数衰减形式，退火曲线可以分成退火常数不同的几段进行拟合。

A charge pump phase locked loop based on self biased technique is presented. In this technique, the operating bias levels are essentially established by the operating frequency of the voltage controlled oscillator, namely, all bias voltages and currents are determined by VCO controlling voltage. Thus, a fixed damping factor and a fixed ratio of the bandwidth to operating frequency are obtained, which are defined by th...

给出了基于自偏置技术的电荷泵锁相环电路，压控振荡器的工作频率动态地建立了电路内部所有的偏置电压和电流，从而实现了固定衰减因子，固定环路带宽与工作频率之比，这二者由电容的比率决定，极大地实现了电路设计的工艺无关性，同时也得到了小的相位抖动，最后，对这种锁相环的稳定性进行了一定的分析。

Thus, Allison need not hold any opinion regarding her daughter's having learning difficulties for her false belief that she is not experiencing difficulties to count as self-deception, since it is her regarding evidence in a motivationally biased way in the face of evidence to the contrary, not her recognition of this evidence, that makes her belief self-deceptive.

因此Allision不需要对有关自己女儿学习障碍方面有任何立场就可以将她对女儿没有障碍的虚假信念算作自我欺骗，因为造成她的信念成为了自我欺骗的是在相反的证据面前用动力引起下具有偏见的一个方式对待证据，即：不承认她的证据。

Post-modernists attack it for being biased, self-deluded and ultimately responsible for the worst in Western civilisation.

后现代主义者抨击它思想上存在偏见，易于自欺欺人并应为西方文明中的糟粕负最大负责。

The experiment result shows that the holes generated by avalanche can be injected into gate oxide of a NMOSFET biased into snapback, and then both hole trapping and interface state generation can be found.

实验结果发现突发击穿，偏置下雪崩热空穴注入NMOSFET栅氧化层，产生界面态，同时空穴会陷落在氧化层中。

Sina Technology: Softbank investment in China has been biased towards the Internet, which is why

新浪科技：软银在中国的投资一直偏重互联网，这是为什么？

Sina Technology: Softbank will therefore develop a new strategy, for example, in the investment of Chinese enterprises to do some biased towards

新浪科技：软银是否会因此制定新的策略，比如在投资上对中国企业做一些偏重？

We found that Efron and Thisted's estimates tend to be less stable and slow in convergence. On the other hand, the estimates of Jackknife, Bootstrap, and Chao are likely to be over-biased.

研究发现Efron and Thisted的模型的估计量容易呈现不稳定的震荡，可能会有无法收歛的问题；而Bootstrap、Jackknife与Chao(1992)则会有高估母体种类数的现象。

If such selection is not taken into account, statistical estimation of economic relationships yields biased results.

以前，经济学界对这样的选择进行的经验研究缺乏经济理论基础。

This valve's spring support structure, has overcome the traditional stopcock leak-proof energy balance, and easy to rust away the flaw, the alone biased seal design, compared the traditional stopcock to reduce the operation pitch of strand greatly, and maximum limit reduced the packing surface attrition, lengthened valve's service life.

该阀的弹性座结构，克服了传统旋塞阀密封性能差且易锈蚀的缺陷，独具的偏心密封设计，较传统旋塞阀大大降低了操作扭距，且最大限度地减少了密封面的磨损，延长了阀门的使用寿命。

The system can be widely used in belt weighing and batching process control,etc.
