LL(1)语法分析器，在任何时候，总控程序都是按照栈顶符号X和当前输入符号a行事的。对于任何（X，a），总控程序每次都执行下述三种可能的动作之一： 若X＝a＝’＃’，则宣布分析成功，停止分析过程； 若X＝a≠’＃’，则把X从栈顶逐出，让a指向下一输入符号； 若X是一个非终结符，则查看分析表M。若M中存放着一条关于X的产生式，那么，首先把X逐出栈顶，然后，把产生式的右部符号按反序一一推进栈，同时做这个产生式相应的语义动作（目前不管）。若M[X，a]中存放着一条出错标志，则调用出错诊查程序Error。

Because of the poor observability of Inertial Navigation System on stationary base, the estimation error of the azimuth will converge very slowly in initial alignment by means of Kalmari filtering, and making the time initial alignment is longer. In this paper, a fast estimation method of the azimuth error is creatively proposed for the initial alignment of INS on stationary base. On the basis of the the fast convergence of the leveling error, the azimuth error can be directly calculated. By means of this fast initial alignment method, the time of initial alignment is reduced greatly. The computer simulation results illustrate the efficiency of the method.

This paper provides a rigorous comprehensive approach to the design of the principal software algorithmsutilized inmodern-day strapdown inertial navigationsystems: integration of angular rate into attitude, acceleration transformation/integration into velocity, and integration of velocity into position.

The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control and data transfer communication between ICs. Some of the features of the I2C bus are: • Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A 12V supply line (500mA max.) for powering the peripherals often may be present. • Each device connected to the bus is software addressable by a unique address and simple master/ slave relationships exist at all times masters can operate as master-transmitters or as master-receivers. • The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data corruption if two or more masters simultaneously initiate data transfer systems. • Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard mode or up to 400 KBit/s in the fast mode.

The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slewrate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.

simulating a convolutional encoder allows the user to input a source code to be encoded and also input the values of the generator polynomials. It outputs the encoded data bits, where 1/n is the code rate
