来自主题: Military2版 - 新中型坦克为什么不用120mm主炮
已有轻坦克和轮式装甲车配备120mm主炮。
瑞典的CV90-120-T就是120mm主炮,但没人买。
意大利的Centauro轮式装甲车也有120mm主炮版,意大利计划将135台Centauro从105mm
升级到120mm。阿曼也有9台Centauro轮式装甲车配备120mm主炮。

稍微缩短一些的话,对于105mm主炮,在射APFSDS的时候,打击效果哪个好?

两个头我都用过,28-300mm有点重。挂在D750上有点头重脚轻的感觉。
这种一镜走天下,走得不是很爽。
Nikon 24-120mm挂在D750上平衡要好多了。(虽然还是头还是有点重)
画质自我感觉 24-120mm 稍胜。
24-120mm价格低主要是做套头的原因吧。
这个价位,另外一个就是 tarom 24-70mm 可能更好。

新中型坦克,35吨,为什么不用120mm主炮,后坐力受不了吗?如果120mm口径把倍径稍微缩短一些的话,对于105mm主炮,在射APFSDS的时候,打击效果哪个好?

一个是狗头,一个是牛尾。
一个是天下第一驴头,一个是N+千呼万唤屎出来的C+ 24-105/4L的替代品.
当年刚出来的时候,把24-120,28-300都预定了。
后来迫于LD压力,只好咳嗽了24-120。
现在不死心,还是想定一个24-120mm。
但是怕买回来,给LD一演示,发现没区别,以后再申请经费都难了。

这两张都是300mm光线不错的时候。说老实话是我已经完全不能接受的画质。看你个人
的标准了
24-120mm 全开则是完全可以做到数毛,放大二倍多不见得比这种300mm差,光圈还大一
档。另外24比28在广角端效果差别还是很大的

旅游过了过了120mm 就没啥用处了。 如果是旅游的话,建议你看看24-85mm f/2.8-4
那只。卖了20年了。

来自主题: Hardware版 - 最近研究的120mm风扇
一个风扇大概有三个重要指标:第一个是出风量,一般用cubic feet/min来衡量,或者
用m^3/h来衡量。1 m^3/h大概是0.59 cfm。第二是噪音。这个很重要,下面会细说。其
实还有一个大家比较忽视的,就是风压。一般来说和出风量成正比,但是有时候却不一
定。风压太低的话,用来做cpu风扇也许会影响散热效果,特别对于那些鳍片排列紧密
,数量众多的散热器。
噪音最主要还是来自气流声。所以不能期望高速风扇会很安静。一般对于120mm风扇来
说1500rpm就很吵了,1200rpm可以接受,而1000rpm以下算安静。
转速都在中低速的时候,这就是厂商展现风扇叶片设计和马达设计实力的地方了。电机
小的话,中间没有风的死角会减小,相同转速出风量可以高一点,这就是scythe slip
stream的设计思路。叶片一般要呈一点曲线,scythe gentle typhoon就是这么设计的
。还有叶片一定是奇数,因为这样可以减少谐振。又例如noctua p12特殊的叶片,改变
了噪音曲线。
马达的设计一般很难看到。不过有些风扇在全速12v的时候表现良好,到了5v低速的时
候却会出现电机

This fan is known for its low noise and not air flow. Don't get it if the
flow rate is the main consideration.
