LL(1)語法分析器，在任何時(shí)候，總控程序都是按照棧頂符號(hào)X和當(dāng)前輸入符號(hào)a行事的。對(duì)于任何（X，a），總控程序每次都執(zhí)行下述三種可能的動(dòng)作之一： 若X＝a＝’＃’，則宣布分析成功，停止分析過程； 若X＝a≠’＃’，則把X從棧頂逐出，讓a指向下一輸入符號(hào)； 若X是一個(gè)非終結(jié)符，則查看分析表M。若M中存放著一條關(guān)于X的產(chǎn)生式，那么，首先把X逐出棧頂，然后，把產(chǎn)生式的右部符號(hào)按反序一一推進(jìn)棧，同時(shí)做這個(gè)產(chǎn)生式相應(yīng)的語義動(dòng)作（目前不管）。若M[X，a]中存放著一條出錯(cuò)標(biāo)志，則調(diào)用出錯(cuò)診查程序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.

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.
