We choose the TMS320VC5402, digital signal processor, as the computing unit, filtering the sampled signal, truncating the harmonic whose frequence greater than 2500hz, then we use the window-interpolation FFT algorithm to get the refined frequence, amplitude, phase of harmonic in sampled voltage and current, other parameter such as harmonic ratio, active power, reactive power, power factor, three-phase unbalance can be also computed base one the result of window-interpolation FFT.

选用TMS320VC5402高速数字信号处理器作为运算单元，先对采样信号进行数字滤波，去除50次以上谐波分量，然后应用加窗双峰插值FFT算法计算电压电流的各次谐波频率、幅值和相位，以及谐波含有率、有功功率、无功功率、三相不平衡度等各项电能指标，同时利用锁相环电路硬件跟踪电网频率以减小采样失步度。

Implementing the hashCode method this way means that it requires no computations and that every possible value for an Integer object is its own unique hash code value.

实施hashCode方法这种方式意味着它不需要计算，每一个可能的值为整数对象是自己独特的散列代码值。

The model is usually an inhomogeneous system of linear equations. It is pointed out that the general solution of the homogeneous system of linear equations can satisfy the request of making the wires tight, and the special solution of the inhomogeneous system of linear equations are not smaller than zero, so their sum is greater than a given mumble.

由于多自由度绳牵引并联机构的静力学模型一般是一个非齐次线性方程组，本文指出可让对应齐次方程组的通解的最小值满足绳保持张紧的条件；让非齐次线性方程组的特解非负，而避免利用对应齐次线性方程组的通解保证非齐次线性方程组的解不小于给定的最小值。

We consider the existence of positive solutions of second order impulsive boundary value problems by constructing the appropriate homotopy operator and applying the theory of fixed point index in cones. our results contain the conclusion when f ≥ 0 and J_k = 0([6]). Secondly, we discuss multiple positive solutions of the following impulsive boundary

其次，我们在§2.2中讨论了下面的脉冲微分边值问题多正解的存在性在这一部分的讨论中，利用不动点指数理论，在f既非超线性又非次线性的情形下，得到了两个正解的存在性定理，把文[7]的结果推广到脉冲微分边值

The concentration-response curves for ATP with and without preapplication of hypotonicity showed that preapplication of hypotonicity shifted the curve downward; maximal amplitude of IATP with hypotonicity decreased by 25.26±2.41%, while the threshold value remained unchanged; the EC50 value of the two curves were very close(1.19×10-4M vs 1.33×10-4M).

3在低渗透压(260mOsm)环境下，ATP-激活电流的浓度反应曲线明显下移；阈值和最大反应浓度不变，EC50为1.19×10-4M，与单独加ATP时的1.33×10-4M基本一致；而最大反应浓度时的ATP电流幅值减小了25.26±2.41%(n=6)。

When using these values in protocol messages, the quotes MUST NOT be used as part of the value.

当在协议消息中使用这些值时，引号不能作为值的一部分。

We also find two species can coexist only when taking the medium values in some range of parameter,if it is too large or too small only one population can exist or none of them can .

其它的参数不变，而只变化某一个参数的取值，且这一取值变化符合这一参数划分区间，定态会经历这一区间内的多种状态，且会出现临界点，普通渗流与定向渗流类相互转化，且出现两个临界点，两次相转变。

User errors include deleting the wrong rows because of incorrect values in a WHERE clause, updating rows with incorrect values, dropping the wrong index, and so forth.

常见的用户操作中的逻辑错误有：因为在 WHERE 子句中使用了不正确的值而删除了错误的数据行，将数据行更新为错误的值，错误地移除了索引等。

One way of estimating an initial value for the reactance of the CLI and of knowing how different inductive reactance magnitudes perform in a particular bus or line is to plot these values against the fault current at a particular bus.

估计CLI电抗的初始值和了解不同感抗幅值在一条特定的母线或线路中表现如何的一种方法是将这些数值针对特定母线的故障电流绘制成图。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
