The beacon fire starts from the number
Wang Liang, who had entered the War of Resistance, realized that as long as he killed the Japanese, he could obtain weapons, equipment, a basic arsenal, a clothing factory, an advanced pharmaceutical factory, and other rewards.
Therefore, the codename of one of them was "Wolf Fang", which made the devils terrified.
The army was born.
Li Yunlong: "Mountain Cannon Battalion, Machine Gun Battalion, Cavalry Battalion, Armored Battalion, Rocket Cannon Battalion, Aerial Unit, Military Dog Unit, Communication Unit, Anti-Fraud Unit, Field Hospital, Munitions Factory, Farm…You, Crazy Wang, are really a rich man. But what does this anti-fraud team do?"
"A Japanese regiment was wiped out?" Beautiful! Which division did it? What was that? The Wolf Fang Regiment of the Eighth Route Army?"
Wang Liang: "Let me introduce you. Our Wolf Fang Regiment's political commissar (in charge of intelligence) Zheng Yaoxian, deputy regiment commander (in charge of military) Zhou Weiguo, chief of staff Li Daineng, and logistics director Ding Abacus."
"Wang Sang, I've seen your sincerity. I welcome you to join us." You are now appointed as the Chief Financial Advisor of the Ministry of Finance and the Department of Economics of the General Administration of Public Security of Jin Province, the Inspector of the Police Department and the Chief of the Security Section, and the Inspector General of the Third Group of the Public Security Army."
Vector Addition and Subtraction Suppose a particle undergoes a displacement followed by a second displacement . The final result is the same as if the particle had started at the same initial point and undergone a single displacement (Fig. 1.11a). We call displacement the vector sum, or resultant, of displacements and We express this relationship symbolically as (1.2) The boldface plus sign emphasizes that adding two vector quantities requires a geometrical process and is not the same operation as adding two scalar quantities such as In vector addition we usually place the tail of the second vector at the head, or tip, of the first vector (Fig. 1.11a). If we make the displacements and in reverse order, with first and second, the result is the same (Fig. 1.11b). Thus (1.3) This shows that the order of terms in a vector sum doesn’t matter. In other words, vector addition obeys the commutative law. Figure 1.11c shows another way to represent the vector sum: If vectors and are both drawn with their tails at the same point, vector is the diagonal of a parallelogram constructed with and as two adjacent sides. CAUTION Magnitudes in vector addition It’s a common error to conclude that if
