The results show that the system can keep certain smoothness with short delay, but the control precision can decline with the accretion of time delay, long random delay will not only reduce system expeditiousness, but also the smoothness and control precision at the same time. If the random delay is long enough, it can destroy the stability of networked control systems.

研究结果表明：系统在较小的延时下仍能保持一定的稳定，随着延时的增大，系统的控制精度有所降低；而较大的随机延时不但降低系统的总体快速性，同时，使系统的稳定性和控制精度明显降低，而当随机延时大到一定程度时，系统的稳定性难以保证。

The effect of grid ceiling can be reduced and the fire extinguishment efficiency can be improved by increasing the water pressure.

增大水压时，格栅时水量的分布的影响会减弱，当压力足够大时，能够接近无格栅时的灭火效率，可以保证自动喷水灭火系统在安装格栅吊顶后的灭火有效性。

In the high-frequency full-power, long tube output should pay special attention to the cooling system is normal, because the full power output of the tube heating than half-power when the high heat four times, when the cooling system abnormalities and easily damaged when the tube

在高频全功率、长时间输出时应特别注意电子管的冷却系统是否正常，因为在全功率输出时的电子管发热量比半功率时的发热量高四倍，当冷却系统异常时及易损坏电子管

When meteorite hit the Earth surface, it created shockwave to transfer the kinetic energy to the Earth surface. When the speed of meteorite strike reached 10 km/second, the pressure of shockwave can reach several millions bar to compress the target terrane to produce heat, the effect of impact deformation caused by it is several scales stronger than rock intensity, the granite would melt down once the pressure of shockwave reached about 500 thousands bar, the granite would gasify (solid became liquid and meanwhile further became gaseity) once reaching over 600 thousand bar.

当陨石撞击地表时产生冲击波把陨石的动能传给地表，在陨击速度达到10公里/秒时冲击波的压力可达到数百万巴并压缩靶点岩层物质产生热，它产生的冲击变形效应比岩石强度大几个量级，冲击波压力约50万巴时花岗岩就熔化，大于60万巴时花岗岩就气化（在固态转为液态同时进一步转为气态）。

Applying MDI ,thc bond strength of plywood achieve national standard when the moisture content of Populus simoniicarr and Liquidambar formosana Hancemoisture are 12% and 20%.With same material and technics ,bond strength of parallel lay-up is higher than upright lay-up.

而当采用异氰酸酯做胶粘剂时，杨木胶合板的含水率在12%，枫木胶合板在含水率20%时达到国家标准要求；⑤材料和工艺相同时，顺纹组坯时的胶合强度高于垂直纹理组坯时的胶合强度。

When one partner has requested that the other bid slam with at least second-round control of a particular suit (the "open" suit) regardless of the rest of his hand, this scheme is used for replier's actions: with no control in the open suit, pass or return to the agreed suit; with second-round control, bid six of the agreed suit (or five notrump with the guarded king); with first-round control, control-bid in the open suit (or, with, additionally, first-round or maximum-possible and an as-yet-unshown control in another suit, control-bid in that suit).

当一方要求另一方在持有特定花色第二轮控制以上的时候应叫上满贯，而不必管手上还剩下什么东西，回答人的应叫方式如下：在开放花色上没有控制时，派司或叫回被同意花色；持有第二轮控制时，叫六阶被同意花色(或持有护卫的K叫5NT)；持有第一轮控制时，在开放花色上做示控叫品(或者，附带性的，第一轮或有高限牌力可能且未叫花色上有尚未表示的控制时，则在此未叫花色上做示控叫品)。

Seems as though Terry purchased what he thought was a Canon A630 from one of the stores CompUSA was closing back in March, but when his step-daughter opened the box a few weeks ago, it was empty. Assuming he'd get a refund, Terry drove to the nearest CompUSA, where he was told that all liquidation sales were handled by a third party and not CompUSA, and that he would have to contact CompUSA's attorneys to secure a refund. Undaunted, Terry then wrote a letter to CompUSA's CEO, whose "Executive Care" assistant replied and said that Terry should have been more careful to inspect the box when he purchased the camera, and that the prominent ALL SALES ARE FINAL signs around the store and on the receipt weren't just for show.

一名德州男子 Terry Heaton 于三月份时，趁着 CompUSA 清仓大甩卖，花了269美金买了一台 Canon A630 数码相机给他的女儿，没想到几周后，他的女儿打开盒子时，才发现原本应该装着相机的盒子却是空的，事后当 Terry 拿着盒子回到店里要求退钱时，却得到「此次清仓拍卖系由接手商品的批发商所负责，而非 CompUSA」的响应，于是不屈不挠的Terry便写了一封信给CompUSA的总裁Roman Ross，没想到却也只是收到「购物时需小心检查商品」及印在收据上的「货物既出，盖不退换」的善意提醒。

First of all,we tested the germination and water uptake rate of 47 species typical xerophil seeds grow up in north China from 20 families,38 genuses under sufficient water and different Grads water stress by high-molecular-weight polyethylene glycol(PEG6000).The results show that Xerophil seeds from the same habitat exhibited similar patterns in response to water stress.Xerophil seeds from arid community were stronger in germination and imbibition than that from other two communities under serious water stress,whereas Xerophil seeds from humid community were sensitive to any degree of water stress.Namely,the seeds live in arid habitat possessed high germination and quickly water uptake in sufficient water or any degree of water stress,but the others grow up in humid habitat shown significant difference which germination and water uptake well under sufficient water but inhibited even if slight water stress.

首先，我们通过对20个科，38属，47种旱生植物种子在水分充足和不同梯度的干旱处理(聚乙二醇PEG6000)条件下的萌发率及吸水率实验发现，当水分胁迫强烈时，分布于干旱沙漠地区的植物种子其吸水率和萌发率都高于半干旱和湿润地区的植物群落，相反，湿润地区植物种子的吸水率和萌发率对任何的水分胁迫都表现出敏感的响应趋势，也就是说，生境恶劣的植物种子在较强的干旱胁迫下，仍然保持了较高较快的萌发率及吸水率，水分充足与水分缺乏时无显著差异，而生境相对较好的植物种子在水分充足情况下萌发与吸水良好，但在干旱胁迫时则受到明显抑制，水分充足与水分缺乏时差异显著。

They found that the joint moments measured at any given motion increased with greater magnitudes of joint displacement, and were significantly larger in the two most caudad facet joints (L4 L5 and L5 S1).62 With lateral bending, strains of the joint capsule tended to be larger in magnitude in the three most caudad joints(L3 S1) during contralateral flexion (i.e., the left facet joints are most strained during right lateral flexion),whereas the two most cephalad joints (L1 L2 and L2 L3)bore the greatest strain during bending to the ipsilateral side.

当向对侧弯曲时侧弯时最尾端(L3 S1)的三个椎体的小关节囊的拉伸强度增大（例如右侧屈曲时左侧小关节达到最大的应力）。而头端的两个关节(L1 L2 和L2 L3)在向同侧屈曲运动时拉伸力量最大。

There existed dual-critical effect of such organic retarders as sucrose and citrin on cement hydration. First, when the amount was relatively low, cement hydration was delayed. While the amount was comparatively high, initial hydration of cement was accelerated, but paste was not hardened after a long time. Second, there existed a critical amount.

蔗糖、柠檬酸对水泥水化历程的调控作用存在双临界效应：一、在掺量较低时，表现为缓凝效果，当掺量较大时，则表现为促凝作用，但是浆体长时间不硬化；二、缓凝效果存在临界掺量值，低于临界值时，缓凝效果随掺量增加而增加，超过此临界值时，缓凝效果随掺量增加而下降。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
