If the inputted accelerations are velocity-zeroized and the Damage Value is calculated according to shear stress extrema, as to 100-meter-high earth dam, Multi-Point Effect is not distinct; But as to 240-meter-high earth dam, in the part where permanent displacement and Damage Value is originally bigger the response is less tenser than that by One-Point Input, and in the part near basement the maximal shear stress and Damage Value is bigger, that is the Multi-Point Effect in time domain.

频域内多点效应与时域内有不一致的地方，即对于240米高的超大型坝，摘要对于竖向永久位移最大的坝顶部位和损伤值原本就比较高的坝顶及斜坡部位，频域内多点输入比单点输入的永久位移和损伤值反应要大些。不一致的原因在于频域内多点作用是通过拟静应力实现的。

Aiming at feature point based image registration, we suggest the concepts of broad sense feature point and narrow sense feature point.

We cannt get result on how to change course and speed to make collision avoidance, this can help little on collision avoidance decision.The article aims at the default on Radar simulator and implements the standard result on Radar simulator by making use of MCU.the main production is below:First, we calculate how to chang course and speed on the destine point by MCU. We get the new course and new speed on the destine point,we get the point to resume original course and speed, we get the distance and azimuth to resume original course and speed on given course and speed, the six essential: DCPA, TCPA, distance, azimuth,real speed and real course.

本论文针对当前雷达模拟器标绘训练中的不足，实现了利用单片机进行雷达模拟器标绘标准值的计算，主要成果有以下方面：首先，利用单片机计算得到了在预定点改变航向和改变航速的计算，求得预定点改向的新航向C_N和预定点变速的新速度V_N，恢复原航向和原航速的时机点的计算；在给定避碰的新航向、航速的条件下，计算出恢复原航向／航速的时机点H的距离R_H和方位θ_H；目标船的六要素，即DCPA、TCPA、距离R、方位θ、真航速V_T和真航向C_T。

The phosphorus forms and BAP vary with horizontal and vertical positions. The total phosphorus, inorganic phosphorus, BAY, and iron-phosphorus contents were high at a depth of 0~20 cm at the first sampling point, and then decreased at 20-40 cm of depth. This shows that the potential release capacity of P at 0-20 cm of depth is higher. The concentrations of total phosphorus and inorganic phosphorus decreased at 0~20 cm of depth and increased at 20~40 cm of depth at the second sampling point, but BAY and Fe-P increased along with the depth consistently. This shows that the deeper layer at the second sampling point had a higher potential release capacity of phosphorus.

不同地点沉积物各磷形态和BAP的垂向变化有较大的差异。1号采样点的总磷、无机磷、铁磷和BAP质量比在沉积0~20 cm处较高，20~40 cm逐渐减小，说明0~20 cm内释磷潜力较大；2号采样点的总磷和无机磷质量比先减小，20~40 cm逐渐增加，而BAP和铁磷质量比随深度增加呈上升趋势，说明2点深层具有较大的释磷潜力。

A device for determining molar mass with freezing point depression was improved, which consists of the Dewar bottle, sample container, Beckmann thermometer, arid motor stirrer, Before the experiment, the freezing point of the coolant was controlled about 2℃ below the freezing point of the sample solution by adjusting the composition of the coolant.

介绍一个改进的凝固点下降法测定摩尔质量实验装置，它由保温瓶、凝固点杯、贝克曼温度计、电动搅拌器等几部分构成。

The so-called cutter location point, the flat end mill tool axis refers to the point of intersection with the bottom tool; for ball-end milling is the ball part of the core; for tools is the tip; the drill is the drill point; for wire electrode cutting machine, it means that the axis line of the electrode surface and the focus of parts.

所谓刀位点，对于平底立铣刀是指刀具轴线与刀具底面的交点；对于球头铣刀是指球头部分的球心；对于车刀是指刀尖；对于钻头是指钻尖；对于线电极切割机床，则是指线电极轴心与零件面的焦点。

Wait because of TV, computer, homework and job as to modern, overspend eyesight, make Eye Maudlin of acerb, look, fatigue, allergic, be afraid that smooth, eyesight drops wait for a problem, often can massage or so brows (assemble bamboo acupuncture point), brow midpoint (piscine waist acupuncture point), brow (traditional stringed and woodwind instrument is empty), midpoint of the socket of eye issueing eyeball , inside canthus (eyeball bright acupuncture point).

Based on the case study, the conclusions were reached that relative positional root mean square error of each point becomes more as distance between the point and datum point becomes more. And the relative deformation offsets under different kinds of datum are helpful for deformation analysis.

从该算例可以看到，各点的相对点位中误差随基准点至该点距离的增大而增大，根据在各种基准下得到的相对形变值有利于进行形变分析。

Two dimensional computer models of the average man, small man, and large man were developed to represent the geometry and movements of operator in seated postures on the basis of analyzing the earth moving machinery's characteristics. The human H point was taken as datum point and the posture angles were linked to easy operation, open vision and comfortable seat. The H point region was obtained by means of CAD technique. The region can be used for design and/or check purposes.
