在进行唾液条件反射分泌实验时,如有一套定时控制的装置,可使实验手续简便,时间亦较准确。现介绍我们设计的一种定时控制装置,供大家参考。本装置系由一个电钟及八个继电器组成,其性能是:(1)控制条件刺激的时间(自5″,10″,15″……至55″);(2)控制施予食物强化的时间(自0″,5″,10″……至55″);(3)记时(5″及10″两种)及记条件刺激和强化的时间。结构及操纵可分为三大部分,见图1。(一)记时部分:用一个具有长三针之电挂钟,六寸大的即可,取出玻璃罩,用膠木板(0.3厘米厚)或其他绝缘板按玻璃罩的大小制成一个环板,环板的内半径要比秒针短些。在相当于0″,5″,10″……和55″的位置,各镶嵌一颗铜质的接触点(0.3厘米大),从每点接出一线;另焊接一线
In salivary conditioned reflex secretion experiments, such as a set of timing control device, the experimental procedures can be simple, time is more accurate. Now we introduce a timing control device designed for your reference. The device consists of an electric clock and eight relays, the performance is: (1) control conditions stimulate the time (from 5 “, 10”, 15 “... to 55”); (2) Of the time (from 0 “, 5”, 10 “... to 55”); (3) Chronograph (5 “and 10” Structure and manipulation can be divided into three parts, see Figure 1. (A) chronograph: a long three-pin with a wall clock, six inches can be large, remove the glass cover, with bakelite (0.3 cm thick) or other insulation board according to the size of the glass cover made of a ring , The inner radius of the ring plate shorter than the second hand. In the equivalent of 0 “, 5”, 10 “... and 55” position, each inlaid with a copper contact point (0.3 cm large), take a line from each point; another welding line
