The purpose of the invetion is to effectively stop the blowoff of an injected fuel into an exhaust port when the opening and closing of valves are overlapped with each other by properly setting the fuel injection direction of a fuel injection device mounted so as to face the intake passage of an internal combustion engine.

提供一种内燃机的进气结构，适当设定被安装成对着内燃机的进气通道的燃料喷射装置的燃料喷射方向，有效防止在气门开闭动作时间的重合期间朝向排气口的喷射燃料的喷泄。

A method for determinating the activities of pectinase was proposed in this paper. It can produce the red-brown amino compounds when 3,5-dinitrosalicylic acid and aldehyde were heated together. The amino compounds had maximum absorbency at 540nm. In certain range, there was a good linear relationship between the amount of reducing sugar and the color of the reaction mixture.

针对QB1502-92标准测定方法测定高活力果胶酶、固定化果胶酶活力存在的实验误差大，重现性及灵敏度差的缺陷，提出了利用3，5-二硝基水杨酸与醛糖共热产生棕红色的氨基化合物，在一定范围内还原糖的量和含有呈色氨基化合物的反应液颜色深浅成正比的原理，在540nm下测其吸光度，从而计算出果胶酶活力的测定方法，并对测定步骤、影响因素及测定中可能出现的问题进行了试验研究。

I was really drawn to Cock because for me, it's about how chaotic and messy we all are, how it's a futile endeavor to constrict people with labels and how frustrating that can be when the labeling starts to impinge on you, your life, and how you interact with people.

我被Cock吸引，因为对我而言，它讲述的是：我们每个人是多么混乱；把人归成特别的类群是多么的无意义；这种归类给你个人，你的生活，你和别人的相处造成的影响是多么令人沮丧。

And the effects of length of data N to the approximate entropy of chaotic system isalso analyzed.All these are accomplished by examining several time series produced by a surperposition of white noise and noise-free data.It uses the discrete system logistic map and continuous system Lorenz attractoras the examples.

以Logistic方程描述的离散系统和Lorenz方程描述的连续系统为例，采用白噪声和无噪声信号以不同的信噪比混迭而成数据的方法，分析了相同数据长度N，不同信噪比下，混沌系统近似熵的变化；相同信噪比，不同数据长度对系统近似熵的影响。

As he did he caught the track, the dissipate and minuscule trace of coppery scent, and just as quickly his eyes adjusted to the darkness, the world spread out in a sharp detail of dusky colored shapes sliced by moonlight silver and streetlamp light.

就如他做的，他捕捉了轨道，那使和消散含铜气味的草写小字痕迹，而且正如很快地他的眼睛对黑暗调整，世界在一件被有月光银和街灯光切成薄片的微暗彩形状的锐利细节中的外传布。

As if she is not a person but a mixture of many people, the dolorous, degage, noblest, pathetic, sagacious, sober, gentler, adorable ……and so on.

仿佛她不是一个人，而是许多人的混合体，忧伤的，从容的，高贵的，可怜的，睿智的，成稳的，可爱的，秀雅的……这是一个令人无法理解的女人，对她度飞抓不住任何头绪。

Generally speaking, attentions paid to Runan's works often emphasized particularly to his head portrait series. If the face was the window to look into the dim recess of one's mind, in the delusively blurry images of his portraits, the window to read one's heart became ambiguous.

一般来说，对汝南的作品关注都会侧重他的头像系列，如果说面孔是认识人的内心深处的窗口，那么他把肖像的面孔处理成模糊的似是而非的形象，这样认识人心灵的窗户就变得暧昧。

The distribution function of the system response and state function is approximately determined by the standard normal distribution functions using Edgeworth series, and its reliability is obtained.

在结构系统响应和状态函数的前四阶矩的一般数学表达式的基础上，使用 Edgeworth级数把未知响应和状态函数的概率分布展开成标准的正态分布表达式，并放松了对随机参数的分布概型和激励类型的限制，从而确定了系统的可靠度

It is researched that the high rate of network addiction in teenagers is caused by special character of their physiological and psychological development. That the teenagers have not been well grown-up in both body and mind, their self-cognizance and interpersonal relation is changeable, the internet has great attraction, and the government is nonstandard and lack of control to the network makes teenager easily enthrall in internet. It is also researched that it is the complex factors which leads teenagers network addiction.

研究认为，青少年成为网络成瘾的高发人群，是与青少年身心发展的特殊性有着密不可分的关系，青少年时期正是人生处在生理和心理都尚未完全发育成熟的特殊时期，他们的自我探索与认同、人际关系等也都处于不断变化之中，再加上网络本身所具有的吸引力，以及政府对网络管理的不规范和严重缺位，这很容易造成青少年在面对网络时出现过度使用和迷恋现象。

Based on the analysis of the great effect caused from temperature on the reliability and the stability of Switch Power Supply Chips, a Proportional to Absolute Temperature current-PTAT current is used to design an original over-temperature protection circuit.

在分析温度对开关电源芯片的可靠性、稳定性有严重影响的基础上，利用与绝对温度成正比的PTAT电流检测温度变化的原理，设计了一种新颖的过温保护电路。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
