不圆

Secondly, we discuss the uncertain discrete-time singular system with control input matrix perturbation.

摘要研究了具有圆盘区域极点约束的一类不确定离散广义系统的鲁棒控制问题。

The placer gold under the lake has high purity,so we called it Golden Lake.the area of the Golden lake is about 136 square kilometers among which the water area is about 26 square kilometers.it's 62 kilometers long,so we also called it "vast Golden lake".the shape of the lake is circular arc,it looks like a crescent.so people feel it is not very big.but at the lower reaches of lake ,it's 2 kilometers wide 5 kilometers long, so-called "ten mile slack water".and we will go there later.

这个湖底下沙金的含量非常高，因为湖底有黄金而取名为大金湖。大金湖的面积有136平方公里，其中水域面积有26平方公里。全长62公里，所以今天我们游览的金湖又有"百里金湖"之称。金湖整个形状呈一个圆弧形，看起来像一轮新月。所以大家觉得这个大金湖看起来不是很大。湖面最宽处是在下游，东西宽2公里，南北长5公里，号称"十里平湖"。呆会儿我们就会到那转一转。

It doesn't appear to be a good way to get a small turning circle.

但这似乎不是一个好方法，得到一个小转折圆。

But it does not follow that the earth is spherical.

但不能因此断定地球是圆的。

Results The shape of these three tortoise erythrocytes keeps spheroidicity with temperature changed.

结果：三种龟红细胞的形状均基本不随温度的变化而改变其椭球形结构，接触面积均呈减小趋势；长径比有增大的趋势；圆度基本上呈减小趋势。

Open a spile , start an electric control valve motor when the job,control valve push in cam circular disc lower open up, lotus seed is followed by pressure to damaged shell knife , shell is cut apart thereupon and flesh is parted from the lotus for on causing a device to fall onto the squeezing claw squeezing a wheel under lotus seed classics, in squeezing a wheel rotating.

工作时，打开插板，启动电动机，控制阀在凸轮圆盘的推动下打开，莲子经下引装置落到挤压轮的挤压爪上，在挤压轮转动中莲子被压向破壳刀轨，于是壳被切开并与莲肉分离。关键的时候翻译不出来，大家帮忙先谢谢哈

It is a large, round, spiny fruit unlike any other. They can be quite big.

榴莲和其他的水果不一样，它又大又圆且多刺。

To square the circle, to determine the exact contents of a circle in square measure .

试图把圆切拼成方形以精确计算其平方值是不可能做到的。

It doesn't interst me what planets are squaring your moon.

是什么磨圆了你的棱角我不感兴趣。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
