MeasurementwiththeLightMicroscope
Measurement with the Light MicroscopeYour microscope may be equipped with a scale (called a reticule) that is built into one eyepiece. The reticule can be used to measure any planar dimension in a microscope field since the ocular can be turned in any direction and the object of interest can be repositioned with the stage manipulators. To measure the length of an object note the number of ocular divisions spanned by ......阅读全文

控制理论基础简介
任何一个闭环系统都可以等效成如下模型:其中H为主拓扑或者主设备传函,K是输出采样比例,C为补偿环节传函。依据此模型我们可以得出如下方程:求解此方程就可以得出:对于补偿环节C,我们经常放一个积分环节。对于这种情况,静态增益或者直流增益是无穷大的,从而:因此对于直流成分,输出便等效成如下方程:我们可以得

什么是暗视野显微镜
暗视野显微镜(dark field microscope)是光学显微镜的一种,也叫超显微镜(ultramicroscope )。暗视野显微镜(dark field microscope)的聚光镜中央有挡光片,使照明光线不直接进入物镜,只允许被标本反射和衍射的光线进入物镜,因而视野的背景是黑的,物

叶绿素荧光技术:常量和微量营养元素胁迫测量
植物生长与各种常量和微量营养元素密切相关,所以测量各种常微量元素对植物的胁迫效应具有很重要的意义。大量的研究表明,Fv/Fm、Yield和ETR是与植物CO2固定能力密切相关的三个参数,所以在研究中倍受瞩目。但我们应该知道,植物营养元素的胁迫除非到了非常严重或者较为严重的程度才会影响到光系统II。这
