Real Time Clock SD 2000 literacy C 51 demo program, the test procedures, the use of confidence.

实时时钟SD2000读写C51演示程序, 程序测试通过, 放心使用.

A Markov chain with finite state, scattered time sequence is put forward as the usage model and test model of the program. The Kullback discriminant is used as the convergence judgment criteria of the test-chain to usage-chain, and the inevitability of the convergence is testified theoretically.

提出具有有限状态、离散时间序列的Markov链作为程序的使用模型和测试模型，使用Kullback判别式作为测试链收敛到使用链的判断准则，从理论上证明了测试链到使用链收敛的必然性。

This test system is designed to test the acting time of motor protector, cutting temperature when temperature rises, and closed temperature when temperature drops. Program compiled with VC++ is implemented for automated test.

该测试系统主要测试在不同的电流和温度条件下，马达保护器的动作时间以及在升温过程中的断开温度和降温过程中的闭合温度，并用VC++设计测试软件实现自动检测。

Flux sensor selects HY-2 type infrared sensor and relates the positive and negative judgement program, which may avoid the bad influence of returning oil pressure wave and improve the test precision of the sensor collecting data at the same time.

流量传感器选用了有两对光敏管的HY-2型红外线传感器，与正反转判断程序相结合，避免了单缸脉冲回油压力波的干扰，提高了数据采集的精度。

In the test there are many problems, such as the efficiency is poor, the program is complex, the time lasts too long, the equipments are not up to standard, and so on so forth.

通过调研发现台阶试验测试中存在的有效性差、程序复杂、耗时多、器材不过关等一系列问题，成为制约高校实施《学生健康体质标准》的瓶颈。
