扩展资料:
附一 文言版《说文解字》:喷,吒也。从口,贲声。一曰鼓鼻。
附二 白话版《说文解字》:喷,张口怒吒。字形采用“口”作边旁,“贲”作声旁。一种说法认为,“喷”是鼓起鼻翼打喷嚏。
词语解释
1、喷泉:喷涌而出的泉水。
《散文》1983年第5期:“喷泉,象玉盘中的一枚珠玑,镶嵌在茵茵的草坪中间。那溅起的水花,晶莹如草尖上的露珠,圆润似稚童的笑涡。”
2、喷溅:(汁液等)受压力向四外射出
秦牧 《花城·在仙人掌丛生的地方》:“一道道波浪不断涌来,撞击在岩石上,发出了天崩地裂的吼声,喷溅着雪白的泡沫。”
3、喷火:使用喷火器喷射高温火焰消灭目标的行动。
杜鹏程 《在和平的日子里》第一章:“不论在太阳喷火的白天或是大风吼叫的夜里,运输材料的汽车、马车、人拉车和牲口驮子,塞满了山沟里的大小道路。”
4、喷薄:气势壮盛,喷涌而起的样子
鲁迅 《集外集·斯巴达之魂》:“﹝ 斯巴达 军﹞与 波斯 军遇。呐喊格击,鲜血倒流,如鸣嘲飞沫,奔腾喷薄於荒矶。”
5、井喷:油气井在钻进或生产过程中,地下的高压原油、天然气突然大量从井口喷出。
刘白羽 《石油英雄之歌》二:“队长头一个冲上去,淋得满头满身是油,制服了井喷。”
谁给解释一下颤振的定义?多谢了
颤振
flutter
弹性结构在均匀气(或液)流中受到空气(或液体)动力、弹性力和惯性力的耦合作用而发生的大幅度振动。它可使飞行器结构破坏,建筑物和桥梁倒塌。发生颤振的必要条件是:结构上的瞬时流体动力与弹性位移之间有相位差,因而使振动的结构有可能从气(或液)流中吸取能量而扩大振幅。最常见的颤振发生在机翼上。当机翼受扰动向上偏离平衡位置后,弹性恢复力使它向下方平衡位置运动,同时产生作用于机翼重心的向上惯性力,因机翼重心在扭心之后,惯性力产生对扭心的力矩而使机翼迎角减小,引起向下的附加气动力,加快机翼向下运动;当机翼运动到下方极限位置而返回向上运动后,出现相反的情况。整个过程中,空气动力是激振力,与飞行速度的二次方成正比;同时还有空气对机翼的阻尼力,与飞行速度成正比。低速时,阻尼力占优势,扰动后的振动逐渐消失,平衡位置是稳定的。当飞行速度超过颤振临界速度后,激振力占优势,平衡位置失稳,产生大幅度振动,导致机翼在很短时间内破坏。防止机翼颤振的最有效方法是使机翼重心前移以减小惯性力矩。设计飞机时,要在风洞中进行模型试验以确定颤振临界速度。飞机研制成功后,还需进行飞行颤振试验。
弯通球、刀型耐磨浆液阀、链轮刀型耐磨浆液阀、超短型球阀、圆刀式浆液阀都怎么翻译呢?

flutter加载h5很卡
flutter加载h5很卡的解决方法如下:
一种临时解决方案,在切换动画加载完毕后,再去构造 WebView,这样从用户角度上看,就不会有路由切换动画的卡顿了。class WebViewPage extends StatefulWidget {undefined
final String uri;
WebViewPage({undefined
@required this.uri,
}) : assert(uri != null);
@override
_WebViewPageState createState() = _WebViewPageState();
}
class _WebViewPageState extends State {undefined
WebViewController _controller;
bool _animationCompleted = false;
@override
Widget build(BuildContext context) {undefined
// 主要是下面的代码
var route = ModalRoute.of(context);
if (route != null !_animationCompleted) {undefined
void handler(status) {undefined
if (status == AnimationStatus.completed) {undefined
route.animation.removeStatusListener(handler);
setState(() {undefined
_animationCompleted = true;
});
}
}
route.animation.addStatusListener(handler);
}
return Scaffold(
title: widget.title,
backgroundColor: Colors.white,
body: _animationCompleted
? WebView(
initialUrl: 'about:blank',
onWebViewCreated: (WebViewController webViewController) {undefined
_controller = webViewController;
_loadHtmlFromAssets();
},
)
: Container(),
);
}
_loadHtmlFromAssets() async {undefined
var uri = Uri.dataFromString(
await rootBundle.loadString(widget.uri),
mimeType: 'text/html',
encoding: Encoding.getByName('utf-8'),
).toString();
_controller.loadUrl(uri);
}
}
Fluent是目前国际上比较流行的商用CFD软件包,在美国的市场占有率为60%,凡是和流体、热传递和化学反应等有关的工业均可使用。
它具有丰富的物理模型、先进的数值方法和强大的前后处理功能,在航空航天、汽车设计、石油天然气和涡轮机设计等方面都有着广泛的应用。
FLUENT软件包含基于压力的分离求解器、基于密度的隐式求解器、基于密度的显式求解器,多求解器技术使FLUENT软件可以用来模拟从不可压缩到高超音速范围内的各种复杂流场。
FLUENT软件包含非常丰富、经过工程确认的物理模型,由于采用了多种求解方法和多重网格加速收敛技术,因而FLUENT能达到最佳的收敛速度和求解精度。
灵活的非结构化网格和基于解的自适应网格技术及成熟的物理模型,可以模拟高超音速流场、传热与相变、化学反应与燃烧、多相流、旋转机械、动/变形网格、噪声、材料加工等复杂机理的流动问题。
