临界值

Moreover, the optimum thickness of ONO stack performs excellently for almost no gate disturbance, no read disturbance and long data retention. Even after 10K P/E cycling stress, the error bit wouldn't happen in such device's sensing window. As a result, the WSG-SONOS memory with split-control gate in NAND array is very adapted for the 2 bit/cell mode with multi-level operation.

此外，利用最佳化的ONO厚度可以达到非常优秀的抗闸极扰动、抗读取扰动与长时间资料保存的能力；即使经过一万次的重覆写入/抹除的操作后，仍能够保有原始的临界电压窗差值并在位元感测区间的范围之内，而不会有位元判断错误的结果发生。

At the same time it researches that when the pigling is 45 days of age,the titer of titer of antibody of sow is higher and it still has protection ability for the pigling and after being immunized concentrated vaccine and common vaccine the pigling and after of antibody raises from transitory decline and after 25 days of immunity the titer of antibody can not reach the critical protective value.

同时研究了仔猪在45日龄时母源抗体效价较高，对仔猪仍然具有保护力，用浓缩疫苗和普通疫苗免疫后，抗体效价由短暂下降至上升，免疫25d后抗体效价达不到临界保护值以上。

According to the analogy between structural mechanics and optimal control, the critical parameter γ-2cr corresponds to the fundamental eigenvalue of a generalized Rayleigh quotient.

按照结构力学与最优控制的模拟关系，Riccati方程解存在的临界参数γ-2cr对应于广义Rayleigh商的一阶本征值。

推导了在假定电弧电压为矩形波条件下，电弧电流的瞬时值数学表达式，明确了电弧连续性与随操作参数I/Is之间关系，推导中考虑了线路电阻的影响；分别求得了电弧连续与不连续情况下的无量纲电气参数；得到了电弧连续性准则；给出了计算临界功率因数的线性高精度近似计算式。

In the study of the stochastic chaos in simple pendulum, the random Melnikov process is derived and the mean-square criterion is used to determine the threshold amplitude of the bounded noise excitation for the onset of the chaos or random chaos in the system. For the coupled simple pendulum and harmonic oscillator, the Melnikov function is used to determine the condition for the onset of chaos in the case of Hamiltonian perturbations. In the case of non-Hamiltonian perturbation, the generalized random Melnikov process and mean-square criterion are used to determine the threshold amplitude of the bounded noise for the onset of random chaos.

在随机混沌研究中，应用随机Melnikov过程的均方准则研究了单摆在有界噪声激励下发生混沌或随机混沌时有界噪声激励的临界幅值；对于耦合的单摆-谐振子系统，先用Melnikov函数研究了在哈密顿扰动下发生混沌的必要条件；然后用推广的随机Melnikov过程方法研究了在非哈密顿扰动下发生随机混沌的必要条件；用最大Lyapunov指数及Poincaré截面方法结果与上述理论结果作了对比。

After undergoing a chaotic region, the period number will add one, in the same time, magnitude of the subharmonic response increases in sequence as the rotational speed ratio increases. When the rotational speed is below the critical speed, the chaotic bands resulted directly from a perioddoubling bifurcation occur among the successive orders of superharmonic responses, then they can return directly to periodic motion by a reversed period-doubling bifurcation.

在转速小于临界转速的情况下，在分岔图中各个连续阶亚谐运动的转换区中分别都出现了经由一个倍周期分岔直接导致的混沌频带，后又直接由一个逆倍周期分岔转化为周期一的运动，同时在三个混沌频带之间都出现了幅值突跳的现象。

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。

Go down on one's knees;kneel down
