This method is based on the Snell law of acoustic propagation in water. Different velocity gradients among linear layers in water are utilized to draw the sound ray chart, and a mathematical model of the geometric operational range is built. Furthermore, the geometric homing range is predicted with sound ray density, a prediction system of geometric operational range for acoustic homing torpedo is designed and the function of the system is realized through a system software. The sea trial demonstrates the prediction validity of the system.

该方法基于声波在水中传播的Snell定律，利用水中各线性分层间不同的声速梯度，绘制声线图，建立了几何自导作用距离的数学模型，并通过声线密度对几何作用距离进行预报，设计了声自导鱼雷几何作用距离预报系统，并通过系统软件实现了其功能，经测试，该系统在海上试验中取得了良好效果。

This made her sorry for the creatures which live in there, which she calls fish, for she continues to fasten names on to things that don't need them and don't come when they are called by them, which is a matter of no consequence to her, as she is such a numskull anyway; so she got a lot of them out and brought them in last night and put them in my bed to keep warm, but I have noticed them now and them all day, and I don't see that they are any happier there than they were before, only quieter.

这件事使她很同情被她称为鱼的水中生物，因为她仍在为那些不需要名字的东西取名，即使她用她取的名称叫这些东西，它们也不到她面前来，这真是一件费力不讨好的事，可她正是这样一个笨蛋了；所以，昨天晚上，她捞上来许多鱼带回来，放在我的床上暖和，今天一整天我老是在注意着这些东西，但我看不出它们在这儿比在水中更快活些，只是更安静些罢了。

The influenced of sodium hexame taphospha on the dispersion of nano-ZnO in glaze,and its effects on chinaware products were investigated,in which sedimentation test,granularity analysis,rheology of glaze,reflet of chinaware and sintering temperature were used to characterize the aqueous and glaze systems with nano-ZnO and chinaware products.

研究了六偏磷酸钠对纳米ZnO在水中和陶瓷釉料中的分散性以及纳米ZnO对陶瓷成品性能的影响。采用沉降实验、粒度分析、釉料流变性、陶瓷成品光泽度、烧成温度测试手段，对含纳米ZnO的水溶液、釉料和陶瓷成品进行表征。结果表明，在实验条件下，纳米ZnO在水中最佳分散条件为：0.5%六偏磷酸钠，3.0%纳米ZnO，pH为9。

Peeled potatoes cut into small pieces after, immersed in cold water for more than half an hour, so that solanine remaining dissolved in the water.

去皮的土豆切成小块后，在寒冷的水中浸泡半个多小时，使剩余的龙葵素溶解在水中。

In view of the key problem of subminiature underwater robots, structural improving,control algorithm and underwater experiment is studied. They can be described as follow: Firstly, the subminiature underwater robot should be compact in size and low cost, for which, it is difficult for us to control its balance. So that, a new kind of piston--style ups and downs system was invented, which can keep the underwater robot horizontally suspended in the water without driving force.

中文摘要本文针对超小型水下机器人在运动中存在的问题，设计了一种新的超小型水下机器人的沉浮结构形式，着重研究了其运动学动力学性能、探讨了相应控制算法、进行了水下试验，具体研究内容如下：首先，超小型水下机器人由于体积小重量轻，在水中沉浮时悬停平衡控制困难，为此进行了一种新的活塞式沉浮系统设计，该系统使水下机器人能够在无动力驱动的情况下，使其呈水平状态稳定悬浮在水中。

to diagnose the deathful cause of drowning and postmortem submergence above 12 hours integrated analysis be made including local environment, appeaance of the dead, diatom and the content of sr in water and blood.

实验表明尸体在水中浸泡时间对血锶含量有显著影响，所以超过12h以上的水中尸体，须结合当地环境，尸体现象，硅藻检验，溺死水源及血锶离子含量等多因素综合分析，确定死因。

The results showed that 1,5-naphthalene disulfonic acid could be degradated effectively by the catalytic supercritical water oxidation process,the removal rate of COD reached 98% or even above;the removal rate of COD increased with the increasing of temperature and residence time,the orders of catalytic oxidation degradation reaction of 1,5-naphthalene disulfonic acid to COD and oxygen in supereritieal water were 0.89 and 0.28 respectively,and the activation energy was 56.8 kJ/mol.

Ding等[3]研究了NH3在MnO2/CeO2催化剂作用下在超临界水中的降解情况；Savage[4]简述了在超临界水中以CARULIFE 150、TiO2、MnO2、CuO为催化剂，对苯酚进行了超临界水氧化机理研究情况，但迄今为止涉及催化超临界水氧化的反应动力学的研究还不多。萘系有机污染物是印染

ARSX / ARSH series of micro-exhaust valve ARSX / ARSH series in general, the water contains about 2VOL% of dissolved air in water during the air released from the water constantly, gathered at the high point of pipeline, and forms Air Bag to make water Plug Valves With Single Or Double Flush more difficult, the system's water capacity could be reduced by about 5-15%, therefore.

ARSX/ARSH系列微量排气阀ARSX/ARSH 系列在一般情况下，水中约含2VOL%的溶解空气，在输水过程中，这些空气由水中不断地释放出来，聚集在管线的高点处，形成空气袋使输水变得困难，系统的输水能力可因此下降约5-15%。
