感知

A man without any failures, in some sense, is a poor man. He can't know the joys of hopefulness and the pains of struggle.

一个没有遭受过失败挫折的人，在某种意义上，是个可怜虫，因为他无法感知希望的喜悦，也无从体会奋斗的艰辛。

Then the fa is, as it were, houseless, and it becomes invisible to bodily eyes (though clearly perceptible by direct awareness to other far).

同时灵魂也就无家可归，且无法再为肉眼所见了。（不过，其他灵魂却可以清楚地感知到它的存在

This artical summarized the research progress on hydrotropism of plant root system internationally from three aspects such as,how to induce hydrotropism by roots, root cap is the site of apperceiving humidity gradient,and the research on hydrotropism at the molecular level.

主要从根部如何诱导向水性、根冠是感知度梯度部位及在分子水平对向水性研究3个方面，总结了国际上植物根系向水性研究的进展。

Based on analyzing the multilayer perceptron neural network,it induces the error backpropagation algorithm while taking the hyperboloid tangential function as nonlinear activation function.

在分析多层感知器神经网络的基础上，推导了双曲正切函数为激励函数的误差后向传播算法。

The analytical results show that the image distortions from the watermark are spread throughout the whole image and are spread into the three channels of a color host image by a hypercomplex inverse Fourier transform. So the proposed watermarking algorithm can realize a good combination for the imperceptibility and security of the watermark.

分析表明提出的方法通过超复数傅氏逆变换，可以把水印带来的误差扩散到整幅图像，并且是分散到红、绿、蓝三色的各个分量上，从而实现数字水印的不易感知性和安全性的良好结合。

Suzy Dittmar, a cognitive behaviour therapist and hypnotherapist at the Hale Clinic, Central London, says: I advise clients to imagine that they are in, say, a blue egg on the Tube.

来自伦敦市中心地区Hale诊所的感知行为治疗学家、催眠治疗学家Suzy Dittmar说：我建议人们在地铁上时想象自己是一个蓝色鸡蛋。

Most cases of synaesthesia, however, are idiopathic; it is their normal mode of perception.

大部分的通感是先天的，这是一种正常的感知方式。

In the second part, we studied blind source separation in ill conditioned cases, obtained the sufficient and necessary conditions on solvability, and presented the neural network model and corresponding adaptive algorithm. We also discussed the blind digital source separation, established the blind separation and extration models and algorithms. These algorithms can be used to deal with high noise and ill-conditioned cases.

在第二部分，我们研究了奇异混合情形下信号盲分离问题，给出了神经网络模型及相应的自适应算法；我们也研究了数字信号盲分离问题，得到了有关可解性的充要条件，提出了分别处理低噪声问题和高噪声问题的算法，这些算法对感知信号个数少于源信号个数等病态问题也适用。

From literatures, the possible elements that might impact players' perceptions and cognitive fun in regarding to the game interface and game mechnics are respectively as follows:(1) game interface - functions, vividness and imaginativeness;(2) game mechincs - structure, challenge and satisfaction.

本研究主要著墨於，影响感知和认知乐趣的游戏介面及游戏机制之可玩性设计。
