"I personally feel that there is still a little luck in this, After breaking up the colony, For a few more minutes, I don't know, Because this is the first time I have met such an 'opponent', No one has experience, Anyway, one is counted as one, It is true that there is no end to shooting with guns. Fortunately, there were flamethrowers prepared to counter the impact on the position at that time. The model I remember was 74, At that time, it was still a relatively new model. In terms of performance, The direct firing distance of '74-jet' (abbreviation of 74-type flame thrower) is about 50-75 meters. If the soldiers who operate it are not specially trained, Generally, only straight-line targets can be hit, It's a little bit of a slope, But in the hands of specially trained veterans, '74 Jet' can fire into that air, Although the range is much less than that of direct shooting, Only 25-30 meters, But after all, he didn't take it to the plane, It is used to deal with enemies in low-rise buildings in street battles. Therefore, it is enough, but it is quite dangerous to spray high-altitude targets with flamethrowers. After all, the fuel sprayed out is liquid. Once the distance and wind direction are not grasped well, it is easy to let the fuel sprayed out fall back again. If it accidentally splashes on oneself, it is really a "fire".It is easy to see that OvR only needs to train N classifiers, while OvO needs to train N (N-1)/2 classifiers, so the storage overhead and test time overhead of OvO are usually larger than OvR. However, in training, each classifier of OVR uses all training samples, while each classifier of OVO only uses samples of two classes. Therefore, when there are many classes, the training time cost of OVO is usually smaller than that of OVR. As for the prediction performance, it depends on the specific data distribution, which is similar in most cases.凌晨风（朱千雪 饰）是新界北冲锋队的警长，一次执行任务中，凌晨风的行动遭到了名为关鼎民（王浩信 饰）的男子的阻挠，最终爆发了一场恶战，凌晨风的父亲凌海（罗乐林 饰）不幸意外丧生，这让凌晨风十分自责，然而，让她没有想到的是，自己竟然拥有了能够使时光倒流的能力，她斗志昂扬回到了事发三日之前，希望能够挽救父亲的性命。秦哥哥就没说丫头的事了，还要帮我呢。往往来说，一场大战能否胜利在于一个关键点，只要抓住了这个关键，将其无限放大，并且利用好。越王现在张口就问蒲俊，这似乎有些为难人啊。　　“花党“的形象顾问【高英洙】由【朴志训】饰演，他是汉阳城里炙手可热的红人，拥有出众的时尚品味和渊博的造型知识，能把任何「非好感」的形象变成「好感型」。【卞宇锡】则饰演情报高手【道俊】，拥有完美的外表、人品、头脑和学识，只可惜家道中落、无缘仕途，刚好马勋看中他无边无际的情报能力，促使他也加入花党，作为花党情报员活跃起来。
