雾中信号

The solution of the cross—fire of signals in the LSSDV three—beam measming system is tested experimentally, the experiment of the simultaneous measurement of spray droplet size distribution and velocity is performed, and the idea of the LSSDV three—beam measuring model is achieved.

用实验验证了LSSDV三光束测量模型中信号串扰问题的解决，并对喷雾水滴的尺寸分布和速度进行了同时测量实验，实现了LSSDV三光束测量模型的设想。

This sensor is highly versalite, able to measure distances both indoors and outdoors, but may have limitations to extremely dark targets or measuring through steam, fog and smoke where the signal is obstructed.

这种传感器是高度通用的，能够穿过室内和室外进行测量，但在极其黑暗的目标或蒸汽环境下测量会受到限制，雾和烟雾中信号也会受阻。

Based on the above analysis and systematic design concept, VC++ language was employed to program for the tree image segmentation system and the tree crown recognition system and some still images were processed by the systems.

论文最后对树形识别系统在农药精确对靶喷雾中的应用进行了分析，从理论上研究了树木的类型同精确喷雾之间的关系，结合已识别出的树形及其相关参数，同时输入喷雾的相关参数，最终确定工作喷头的重叠量δ〓，从而作出判断，输出控制信号，决定工作喷头的数量及可变量喷雾技术的应用，以达到精确喷雾的目的。

While underway, in fog, you hear a whistle signal of one prolonged blast followed by two short blasts.

当雾中在航，你听到一长声接着两短声的气笛信号。

Its working principle is introduced here: when a gas or powder starts a flame or explosion, the ultraviolet sensor will acquire the signal and sent it to the controller to produce the trigger voltage, and then the explosive suppressor will release a great number of gas promptly spraying dry powder extinguishing agents, which thereby form extinguishing agent smoke and effectively extinguish explosion flame. It is rapid and of strong antiinterference ability, high reliability and can be fixed easily. It is capable of effectively suppressing natural gas explosion in the simulative gas explosion test. It can be applied in CNG stations or other site where has explosive and combustible gas whereby to enhance the overall accident control ability.

当发生气体燃烧、爆炸时，紫外传感器接收火焰信号，传送至控制器，控制器产生触发电压，使抑爆器的产气剂释放出大量气体，驱动快速喷撒出干粉灭火剂，形成足够浓度的灭火剂粉雾体，有效扑灭爆炸火焰，具有动作速度快、抗干扰能力强、可靠性高、安装使用方便等优点，在天然气模拟爆炸试验中能有效抑制天然气爆炸，可用于CNG加气站或其他燃烧爆炸性气体场所，提高其整体防灾抗灾能力。

Chromium ore samples were fused by alkali and then leached out by hydrochloric acid. After the analytical lines of the elements were selected, the conditions of sample uptake, carrier gas flow, cooling gas flow and RF power were optimized with the system of SeaSpray nebulizer and cyclone spray chamber, based on the principle of best signal stability. The determination of chromium, aluminum, iron, magnesium and silicon in chromium ores was fulfilled.

铬矿石样品经碱熔融和盐酸浸取后，选用SeaSpray雾化器和旋流雾室，选定了待测元素的分析线，以信号的稳定性为原则，优化了样品提升量、载气流量、冷却气流量和入射功率，实现了电感耦合等离子体原子发射光谱法对铬矿石中铬、铝、铁、镁和硅等主量成分的测定。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
