如何测线对a线对地绝缘电阻?(用小型测量台以WX1键为例、校表)() ["断开局内设备,拔掉保安单元","将表放平、调零,红表笔插入“+”插孔,黑表笔插入“-”插孔","选择档位为“Ω”档,选择量程为R×1K档,进行校表","扳外线1和接表两键,此时表针所指刻度乘以100,即为a线对地绝缘电阻"]

public class SyncTest{ public static void main(String args) { final StringBuffer s1= new StringBuffer(); final StringBuffer s2= new StringBuffer(); new Thread () { public void run() { synchronized(s1) { s2.append(“A”); synchronized(s2) { s2.append(“B”); System.out.print(s1); System.out.print(s2); } } } }.start(); new Thread() { public void run() { synchronized(s2) { s2.append(“C”); synchronized(s1) { s1.append(“D”); System.out.print(s2); System.out.print(s1); } } } }.start(); } } Which two statements are true? () [" The program prints “ABBCAD”"," The program prints “CDDACB”"," The program prints “ADCBADBC”"," The output is a non-deterministic point because of a possible deadlock condition."," The output is dependent on the threading model of the system the program is running on."]
