《走出国门》讲述的是建工集团的建筑工人远赴非洲、柬埔寨历经生死、情感。勇于拼搏以及艰难而又辉煌的历程。该剧反映建筑工人们在踏出国门后的种种经历，以及在恶劣的环境和巨大的压力下，仍要肩负使命，完成任务的不屈精神。"Er... I really can't remember the model, it's green, probably so thick." Wang Zeduan could not remember the specific model of the explosive cylinder, Just said the color and gesticulated the approximate size with his hand, Later, I looked up the information and learned that The detonators used at position 142 were all Type 68 detonators, This is also a classic explosive barrel widely used throughout the Sino-Vietnamese border war. This type of explosive cylinder is 60 centimeters long each, As long as there is a need, it can be spliced indefinitely. The charge for each section is 2.2 kg, According to Wang Zeduan's description, At that time, the explosive barrel was made up of three sections. Then the total charge is as high as 6.6 kg, However, the high explosive bomb used in the type 66 152 mm howitzer, The charge is 6 kg, In other words, The charge of these three explosive cylinders is 0.6 kg higher than that of a 152 mm grenade. This is also basically in line with his description that it is more powerful than a shell. In addition, after being inserted into the ground, the two sections of the upper half form a certain blast height from the ground, In this way, the explosive power can be better exerted virtually to cover a wider area, so it is indeed reasonable that an explosive barrel can successfully achieve the tactical purpose of successfully clearing position 142 for the second time (the first clearance is 66-type directional anti-infantry mines and 72-type pressure/tripping anti-infantry mines).The new BMW 3 Series has very well-equipped chassis protection, and the use of large-area protective plates prevents the oil pipeline from being directly exposed to the bottom of the vehicle. On the other hand, the lower part is equipped with a whole metal guard plate (for the convenience of chassis shooting, the guard plate has been removed and is not shown on the figure), which can provide strong protection for key parts such as engine oil pan. In addition, the guard plate can also comb the airflow passing through the chassis, thus improving the handling performance.Since the single mode is instantiated only once, the first call returns an instance object of a. When we continue to call, the instance of b is the instance of a, so aa is printed below.　　因枪击重伤也住进了衡山医院的蔡里昆本人，正是苏区派来接应朱天德的特派员，他让马天明继续维持假身份，二人结盟与各方恶势力周旋。臣离开的时候，与西楚国尚未有和谈的机会。
