硬

In order to correctly diagnose hard chancre,physicians are expected to generally analyze the case history,clinical features,laboratory examinations including biopsy and dark field examination for Treponema pallidum.

诊断硬下疳仍然需要对患者的病史、临床表现、实验室检查，包括活检以及暗视野检查梅毒螺旋体作综合分析。

The common disorders easily confused with hard chancre were as follows: balanoposthitis,condyloma,acuminatum,genital herpes,folliculitis and furuncle,acute vulvae ulcer,genital tumors,fixed drug eruption,scabics nodules,Behcet's syndrome,chacroid and so on.

易与硬下疳混淆的疾病有龟头包皮炎、尖锐湿疣、生殖器疱疹、生殖器肿瘤、毛囊炎及皮肤非特异性感染、侵蚀性阴部溃疡、白塞综合征、固定性药疹、疥疮结节、软下疳等。

CASE REPORTS The retrospective analysis on258cases of early syphilis which collected from section of venereal disease of Affiliated Hospital of Yanbian University,diagnosed between1998and2004were done.In all cases,cases of primary syphilis was account for25.58%,and secondary syphilis account for51.94%,latent syphilis account for21.32%,early congenital syphilis account for1.16%.Highly rate of contracting syphilis in age group between20～39years old,mostly self-employment,mostly with educational background of high school graduation.Clinical manifestation of primary syphilis were generally featured with indurated chancre,secondary syphilis with rash.

病例报告］对1998年―2004年间延边大学医院性病诊察室诊断并治疗的258例早期梅毒患者进行回顾性分析，见一期梅毒占25.58%，二期梅毒占51.94%，潜伏期梅毒占21.32%，早期先天性梅毒占1.16%；梅毒高发年龄段为20～39岁；职业以个体从业者为居多；学历以中学及中学以下者为居多；临床表现：一期梅毒患者以硬下疳为主，二期梅毒患者以斑疹型皮肤损伤为主。

Through above study, the theoretical analysis of the inherent fault tolerance of feed-forward neural networks has been extended from hard-limit activation functions to differentiable activation functions; 2. By using above method, fault tolerance of discrete Hopfield feedback neural networks have been also analyzed. It means that the above method can be applied not only for feed-forward neural networks but also for feedback neural networks; 3. For the feed-forward neural network with the Sigmoid activation function, Chebyshev Inequality method was presented.

这项研究将以前仅限于对硬限幅作用函数前向神经网络固有容错性能的理论分析推广到具有可微作用函数的前向神经网络； 2 针对离散型Hopfield反馈神经网络，利用上面提出的方法，对其同样进行了容错性分析，得出许多有用的结论和计算公式，说明上面提出的方法不仅适用于前向神经网络，同时也适用于反馈神经网络； 3 针对具有Sigmoid作用函数的前向神经网络提出了一种切比雪夫不等式法。

The difference between the two types of checks are hard for you to see ?

这两种检查的区别就是你所要说的硬解析了。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
