《热情的邻居》2

　　这边儿小马更惨，尽管他爱玛力爱得发狂，书没法读我和她已经没有关系了，形同陌路，又哪来的恨。A low temperature stop valve, Unlike Example 1, Comprises a valve body 1 and a valve cover 2, A valve stem 3 is arrange in that valve body 1, One end of the valve stem 3 is provided with a valve disc 4, The other end of the valve stem 3 is provided with an adjusting handwheel 5, A low portion of that disc 4 is provided with a guide sleeve 6, The guide sleeve 6 is fixed by means of a connecting piece and a spring pad 8, Between that disc 4 and the guide sleeve 6 is provide a valve seat 7, Between that valve stem 3 and the valve cov 2 there is provided a packing assembly 9, The O-ring 10 is further arranged at the upper part of the packing assembly 9, the upper part of the O-ring 10 is provided with a packing gland 11, the valve body 1 is provided with an arc-shaped end face 12, the arc-shaped end face 12 forms a line seal between the valve body 1 and the valve seat 7, the contact end of the valve disc 4 and the valve seat 7 is provided with a water grain surface 41, the packing assembly 9 comprises a flexible graphite packing layer, and the valve body 1 is provided with a liquid inlet cavity and a liquid outlet cavity.For example, if we want to implement a JS function, Such as form validation, Then if we don't use the policy pattern in javascript described in the previous chapter to solve the form validation encapsulation code, It is a temporary form validation function written by itself. Certainly without any encapsulation, Then at this time, we will pop up a prompt to the user for whether the two values are equal. If there is a form verification on another page, their judgment method and business logic are basically the same, but the comparison parameters are different. Should we consider writing a form verification code again? So now we can consider using the template method pattern to solve this problem. Common methods are extracted, and different methods are implemented by specific subclasses. This design code also has the advantages of stronger scalability and better code ~CBS All Access宣布续订《星际迷航：皮卡德》第二季。一位是三次参战的军曹，一位是新来的上尉，在他们的带领下，一支美军突击队在越南的战场为生存而战斗。本片讲述美军一个敢死连某排在越南战场上的各种经历，越南战争是美国历史上历时最长的战争，越战期间，一般美军士兵都要到越南战场服役一年。
