Description: 编写子程序嵌套结构的程序，把整数分别用二进制和八进制形式显示出来。
主程序 ：把整数字变量 存入堆栈，并调用子程序 ；
子程序 ：从堆栈中取出 ；调用二进制显示程序 ，显示出与
其等效的二进制数；输出 个空格；
调用八进制显示程序 ，显示出与其等效的八进制数；调用输出回车
及换行符的子程序。 - 编写子程序嵌套结构的程序，把整数分别用二进制和八进制形式显示出来。

Description: 国际标准，需要收费的，从网上好不容易收集到的，现贡献给大家。-This Standard is part of a group of related Standards. The others are EN 50126 "Railway applications-
The specification and demonstration of Reliability, Availability, Maintainability and Safety (RAMS)î and
EN 50129 "Railway applications- Safety related electronic systems for signalling". EN 50126 addresses
system issues on the widest scale, while EN 50129 addresses the approval process for individual
systems which may exist within the overall railway control and protection system. This Standard
concentrates on the methods which need to be used in order to provide software which meets the
demands for safety integrity which are placed upon it by these wider considerations.
This Standard owes much of its direction to earlier work done by Working Group 9 of IEC/TC 65. The
work of WG 9 resulted in a generic standard for software for safety systems which is now part of
IEC 61508. A particular aspect of the work by WG 9 is its inclusion of Software Integrity Level 0, wh

Description: safeRtos是一个抢占高实时安全的操作系统，特别适合在MCU中高效执行的操作系统。
目前已经嵌入到Luminary mcu 的ROM中，可以免费使用-SAFERTOS was developed using a formal and rigorous process. The process was
certified by TÜ V SÜ D to confirm that it was in compliance with that mandated by IEC
61508 [Reference 3] parts 1 and 3 for Safety Integrity Level (SIL) 3 projects. The same
processes have been used throughout the SAFERTOS development.

Description: The CS5460A is a highly integrated power measurement
solution which combines two
Analog-to-digital Converters (ADCs), high-speed
power calculation functions, and a serial interface
on a single chip. It is designed to accurately measure
and calculate: Real (True) Energy,
Instantaneous Power, IRMS, and VRMS for single
phase 2- or 3-wire power metering applications.
The CS5460A interfaces to a low-cost shunt resistor
or transformer to measure current, and to a
resistive divider or potential transformer to measure
voltage. The CS5460A features a
bi-directional serial interface for communication
with a microcontroller and a pulse output engine for
which the average pulse frequency is proportional
to the real power.

Description: Expansion loop
The pipe will expand with respect to its length Linst , due to the temperature rise t = tmax - tinst
The maximum temperature could be reached due to the pipe temperature and solar radiation,
Steel pipe expansion loop with nominal diameter dn shedule SCH and length Linst . The given length Linst refers to an installation at a temperature tinst . or due to fluid flowing through it.
Similarly, the pipe will shrink due to low temperatures and clear sky nights.
