It will be seen that preputial "adhesions" is an inapposite term to apply to the incompletely separated prepuce, suggesting as it does that the prepuce and glans were formerly separate structures. The age at which complete separation of the prepuce with full retractability spontaneously occurs is shown in Fig. 5, which has been constructed from observations of the prepuce in a series of 100 newborns and about 200 boys of varying ages up to 5 years.

No man was ever so poor that he could express all he has in him by words, looks, or actions; his true knowledge is eternally incommunicable, for it is a knowledge of himself; and his best wisdom comes to him by no process of the mind, but in a supreme self- dictation, which keeps varying from hour to hour in its dictates with the variation of events and circumstances.

没有人是永远这么差，他可以用文字表达他所有，他也期待，或行动，他的真正的知识是永恒的静默，因为这是对自己的知识，以及他的最佳智慧来给他的过程中没有心，但在最高法院自默，这可防止小时不等小时在其与事件和情况的变化驱使。

Results CTVE could clearly demonstrate the shape,size,and relation of the normal auditory ossicular chain.A visualization rate of malleus,incus,and incudomalleal articulation was 100%,and was 32% for the stapedial footplate.However,in only 21% could the anterior and posterior crura of stapes be distinguished.Cholesteatoma was found in 12 cases with chronic otitis media,in which CTVE demonstrated varying degrees of destruction of the auditory ossicle.In 1 case with congenital anomaly,ossicle dysplasia was seen.

ABSTRACT Aiming at problems of trans-vector controller in a vehicle-carried induction motor such as variable rotor and stator resistance following motor temperature, and their inductance varying with flux saturation degrees. Firstly, CSI and VSI are introduced, for CSI, it can hold the advantages both FOC and DTC using stator flux directional, PI parameter and simulation are also introduced. Secondly, equations of IM in the synchronous rotary frame and its static counterpart, as figuring in the saturation condition of magnetic field, are dealt in this paper and the simulation results are presented. Thereafter, the parameter designing of PI trans-vector controller is processed, which features the non-linear model. In practical realization, as neglecting the dynamical change of motor inductance, this paper employs online modification of inductance parameters, according to the flux saturation, then transforms the non-linear equations into linear ones, and so compacts the structure of controller. Thirdly, in view of the maximum torque output is extraordinary requisite when Electrical Vehicle start up, accelerate, and overtake, this paper issues the maximum torque when both inverter and battery capacity is corporeally definite. Fourthly, on-line differentiating and analyzing both rotor's time constants and its flux by using the expanding order reduction and discrete Kalman filter equation are fathomed, in order to realize high-performance trans-vector algorithm, and also the simulation results are presented. Fifthly, the close-loop regenerative brake system, when the EV's torque is set constant, is deduced; at the same time, unification of electric drive model and brake model is executed. Combined with maximum charge current demands, the mathematical model for online yielding torque as a demand.
