首先还是来说说什么是ABS和PLA吧，这里的ABS可不是说“防抱死制动系统”，而是说的一种塑料，ABS英文名为 acrylonitrile–butadiene–styrene copolymer，ABS通常为浅黄色或乳白色的粒料非结晶性树脂，是使用最广泛的通用塑料之一，具体的性能大家直接度娘，在此就不啰嗦了。 再来说说PLA吧，这里也不是指“中国人民解放军”，也是说一种塑料，PLA是聚乳酸的英文简写，全写为： polylactic acid。 既然都是塑料，那性能也就该差不多了吧？ 非也！ 首先来看看我为大家准备 …

The QBS-09 semi-automatic shotgun, also known as the Type 09 shotgun, is a semi-automatic shotgun developed by Norinco of the People's Republic of China. The initial development of the QBS-09 dates back to 1989, with the project officially established in 2005.

The QBS-06 underwater assault rifle (Chinese: QBS06式水下步枪; pinyin: QBS06 shì shuǐ xià bùqiāng) is a Chinese underwater assault rifle modelled after the older Soviet APS rifle. [1] In 2010, the QBS-06 was publicly shown to the public through news videos produced by CCTV. [2] . It was later seen during Chinese-Thai military exercises in the same year.

QLZ-87 - standard fire support grenade launcher of PLAGF for individual usage. FSL02 smoke grenade. The grenade weights 750 grams, and has a length of 140mm with a diameter of 65mm. Duration is 2 minutes at 2-5m/s wind speed. The body has pale green color with white or black band indicating the color of smoke (white/black).

pla 是 fdm 3d 打印中使用最多的材料，主要用于创客环境。 这主要是因为它易于打印，以及它易碎、脆弱且对阳光和高温敏感等特性。 出于这个原因，它经常被新手用户广泛使用或用于创建装饰零件和玩具。

QBS-06 underwater assault rifle uses specially developed 5.8mm DBS-06 ammunition, which is built using lacquered steel cases of the PLA’s general issue 5.8×42 ammunition, loaded with long, needle-like projectiles intended for submersible use.

2021年4月9日 · A video released by the Chinese state media shows PLA Navy commandos, also known as ‘Sea Dragons’, taking part in an underwater training session with needle guns. The weapons used appear to be the QBS-06 rifle and the QSS-05 pistol.

This mod adds QBS-09 as a standalone secondary shotgun. The QBS-09 is a semi-automatic, 12 Gauge, gas piston-operated Chinese shotgun manufactured by Norinco. It was adopted by the PLA and the PAP in 2009 as a standard combat-shotgun.

2022年3月5日 · 本文介绍了三种常见的3D打印材料——PLA、ABS和PETG的特性。 PLA环保无味，适合室内打印，但强度较低；ABS耐高温，强度高，但可能散发气味；PETG结合了两者优点，无气味，强度高且光滑。 每种材料都有其适用场景。 是聚乳酸，这种材料是生物分解性塑料，食品级要求，进口原料，符合食品级要求。 使用过程中没有气味，即使是关着窗在房间里面打印，基本都没有什么气味，健康完全环保。 打印出来 模型 不翘边，无气泡。 产品表面光滑，颜 …

2025年1月25日 · PLA塑料（Poly Lactic Acid，聚乳酸）是一种生物基的热塑性聚合物，由可再生资源如玉米淀粉或蔗糖通过发酵制得。 它在自然界中可生物降解，在工业堆肥条件下可在几个月内完全分解，因此被认为是环保型材料。
