查询词典 threshold intensity

It is shown that the reaction U+CO→CUO with a long-lived intermediate complex has no threshold energy, which agrees with the potenlial surface. When the collision energy is greater than 418.4 kJ/mol, the intercharge reaction increases, until the CUO molecule will decompose into U, C, O completely, and these reactions have threshold energy.

结果表明：在碰撞能低(15kJ/mol)时可以生成长寿命络合物CUO(X^3A)，并且该络合反应是无阈能反应；碰撞能大于418.4kJ/mol后，先后出现置换产物UO和UC；随着碰撞能进一步增大，CUO分子将被完全碰散成U，C和O原子，而且反应U+CO(0， 0)→UO+C，U+CO(0， 0)→UC+O和U+CO(0， 0)→U+O+C是有阈能反应。

Several retracking methods are used to retrack the EnviSat waveform over the Mediterranean Sea. The improved threshold retracking algorithm is the most robust retracking method and more suitable for the EnviSat waveform retracking over the coastal Mediterranean.

Among the 45 neurons generating phasic firing, 8 (17.78﹪) neurons could still be induced phasic firing after treatment with 1×10-2 μg/mL SVHRP and 37 (82.22﹪) neurons had no responses to the stimulation. The AP firing of neurons was dramatically different after treatment with SVHRP (P＜0.01, n=45). Among the 7 repetitive firing neurons, all of them could only generate 1 or 0 AP instead of repetitive firing when SVHRP was applied. The number of APs was 14.57±1.00 and 0.57±0.20 before and after SVHRP treatment (P＜0.01, n=7). The AP rheobase was (75.10±8.99) pA and (119.85± 12.73) pA before and after 1 × 10-4 μg/mL SVHRP application, respectively (P＜0.01,n=8). The AP threshold was increased from (-41.17±2.15) mV to (-32.40±1.48) mV after 1×10-4 μg/mL SVHRP treatment (P＜0.01,n=8). The peak amplitude of AP was (68.49±2.33) mV for the neurons before treatment with 1×10-4 μg/mL SVHRP and (54.71±0.81)mV after treatment (P＜0.01, n=8). These results showed that SVHRP could decrease the AP firing frequency, increase the AP rheobase and threshold, but decrease the AP peak amplitude of hippocampal neurons.

在产生位相放电的45个细胞中，有8个细胞在SVHRP处理后仍可以诱发出位相放电(占17.78﹪)；37个细胞在SVHRP处理后无法诱导出位相放电(占82.22﹪)，SVHRP处理后动作电位的产生与处理前相比，有显著差异(P＜0.01，n=45)；在产生重复放电的7个细胞中，在1×10-2μg/mL SVHRP作用后均不能再次诱发出重复放电，而是产生一个动作电位或不再产生动作电位，药物处理前产生的动作电位个数为14.57±1.00，SVHRP处理后产生动作电位的个数为0.57±0.20，二者之间有显著性差异(P＜0.01，n=7)。1×10-4 μg/mLSVHRP处理后，诱发动作电位产生的基强度由(75.10±8.99)pA增加到(119.85±12.73)pA(P＜0.01，n=8)；阈电位由(-41.17±2.15)mV升至(-32.40±1.48)mV(P＜0.01，n=8)；动作电位峰值由(68.49±2.33)mV下降至(54.71±0.81)mV(P＜0.01，n=8)。

The field experiments on the near surface airflow, sand transport rate, grain size of the dune sands and the morphology of the dunes show that though shear velocity decreased at the toe of the transverse dune, the threshold shear velocity decreased simultaneously. The decreased threshold shear velocity and unsaturated sand flows at the stoss slope of the dunes resulted the erosion at the toe of the dune.

对简单横向沙丘表面的气流、输沙率、物质结构，以及形态学特征的观测表明，在横向沙丘迎风坡坡脚尽管剪切速度有所下降，但起动剪切速度同时减小，起动剪切速度减小与不饱和风沙流是沙物质在迎风坡坡脚不能产生沉积的主要原因。

It showed that TPP is superior to bipole pacing in lowering pacing threshold, decreasing pulse breadth, keeping stable pacing and lessening of discomfort of the patients. Bipositive pole pacing is simpler in lowering pacing threshold and gives clearer pacing P wave and thus it is superior to hinegative pole pacing in TPP which is of practical value in TEAP.

但是，传统方法即二极起搏法的TEAP仍有许多不足之处，诸如：起搏阅值偏高，不适感觉常见而且明显，起搏效果欠稳定，脉冲波幅较大，伪迹明显等。

This paper brings forward a approach for textile flaw automatic detection based on optimal Gabor filters.

为了对织物缺陷进行快速准确的自动检测，建立了一种基于Gabor滤波器的织物缺陷自动检测方法，即首先根据无缺陷织物的结构特征，应用小生境遗传算法寻找最优的Gabor滤波器参数和分割阈值；然后将待检图像通过滤波和分割来得到检测结果，同时根据响应矩阵的极小值点来计算缺陷的形状特征。

A series of experiments were done to substantiate the feasibility of the different piezoelectric cochlea implants in vitro and in vivo . The unpoled ceramic had no piezoelectric characteristic and no ability to decrease the threshold, while the poled ceramic had obvious piezoelectric effect to recover the hearing. Based on these results, it can be affirmed that the piezoelectric cochlea implant can activate the nerve and decrease the threshold.

本研究通过未极化与极化的高灵敏性压电陶瓷的对比，从体外模拟实验中的声电响应曲线和动物体内植入实验的结果中得到：未极化的压电陶瓷没有压电响应，而极化后的压电陶瓷能够将声音信号转化为电信号，证实了压电陶瓷的压电特性的确可以刺激动物的听神经，从而降低听阈阈值。

Great. What repertoire did you see?

I prepared not to accept such ridiculousness:"Please," I said to him.

我可不想理会这套荒谬的东西："请你通情达理一点儿。"
