压榨iPhone7,拍几张近距离微距 拍的电路板,拿了一根暖色调强光手电贴了纸胶布作为柔光源补的光,要清晰还得是补光和对焦。

尾架支撑DIY 原支撑杆老是震松,骑上一段距离就会松,网上搜了一圈成品没有可堪一用的,因为经常工作通勤,偶尔会载重货。快拆的那种铝合金尾架一摔就松或者断,换成这种钢的尾架是坚固了但是支撑杆设计本身就有问题导致松,搜了一圈没有可靠的设计的产品,只能自己动手折腾个坚固的。

[....]我决定,以后发能材贴就只用英文 RT 估计原先的大号被封没做好防HX措施
About synthesis of ΗexaΜethylene Τriperoxide Diamine. RT About the yield relation with the reaction temperature. Use measure of reagent:Urotropine 10.64g; Hydrogen peroxide 30ml 30%; Phosphoric aid 10ml 85%. In process of reaction,controlled and kept reaction temperature to about 36~40℃,but below to 50℃,the yield was highest.Finally,for got the solution is very viscous. But if controlled and kept reaction temperature to below 30℃,the yield is lower than.Finally,for got the solution is diluted.
【。。。】妹的。。。。 RT 被封了,只好用小号了
