密度

But the reality is: fotographic control is simple, use the transmissional density gauge makes it easy to control the density and linear.

而本质的环境是：胶片的把持比力单一，搁置透射密度仪可以很便当把持密度和线性。

The basic principle is that for exposure changing the transmissivity τ is equal to changing the exposure time t .

利用改变曝光时间t和改变透射率τ对曝光量的改变是完全等价的这一原理，不用借助任何标准密度灰片校准，可在大面积上足够精准地测量物体透射密度

Based on density functional theory with the generalized gradient approximation and a full-potential linearized augmented plane wave method, the calculation of the electronic structures and the magnetic properties on [Cuμ-1,3-N3](ClO4), where L is the tridentate Shiff base, has been performed.

基于广义梯度近似密度泛函和全势能线性缀加平面波方法，本文对聚铜络合物[Cuμ1，3-N3](ClO4)（其中L=tridentate Schiff base为三齿席夫基）的态密度和磁矩进行了计算。

Results: After the therapy their high density lipoprotein cholesterol rose significantly(P＜0.05), the low density lipoprotein cholesterol dropped significantly(P＜0.05). Their glycerin trinitrate fat didn't change obviously.

结果：用药后高密度脂蛋白胆固醇明显上升（P.05），低密度脂蛋白胆固醇明显下降（P.05），甘油三脂无明显变化。

In plain CT images, 6 cases with hypointense, 4 cases with isointense, and all the tumor tubercula were highly enhanced.

CT平扫低密度6例，等密度4例，增强扫描全部肿瘤结节明显强化。

MTT may be used as a new photosensitizer underlight,non-light and different light energy intensity,with no toxic effectto C6 cells under non-light and increased toxicity under increased lightenergy intensity.

在光与非光、及不同光能量密度条件下应用MTT有可能成为新一代的光敏剂，其在非光照射时对C6无细胞毒作用，其细胞毒作用随光能量密度的增加而增强。

Since the density of gas is far lower than that of water,the sum pressure mentioned above is smaller than that of two parts being both water,and the deep basin gas pool behaves the underpressure feature.

由于气体的密度远小于水的密度，因此上述气水两段压力之和小于该两段都为静水柱时的压力之和，所以深盆气藏表现为负压异常。

以前塔里木油田在盐岩层应用的高密度饱和盐水钻井液体系曾取得了良好的应用效果，但该体系仍有一些弱点尚未克服，如高密度 2 0～ 2

Regarding the density data and acoustic data in logging material as restriction, it also establishes undrilled district log through model seismic inverse, then, calculates elastic constant of rocks, density constant of rocks and even the profile of the following three pressures (pore pressure, caving pressure, fracture pressure). In the end, this thesis can determine safe drilling mud density windows, provide reference for drilling design, guides safe drilling and decreases the occurrence of accident.

将测井资料中的密度数据或是声波数据作为约束条件，通过模型地震反演，构建待钻区域的测井曲线，从而可以用理论和处理手段上比较成熟的测井分析的方法，进行岩石弹性和强度参数的计算，计算地层的三个压力(孔隙压力、坍塌压力、破裂压力)剖面，最终确定安全钻井液密度窗口，为钻井设计提供参考，指导安全钻井，减少钻井事故。

Soft-tissue masses: abut against bone leision, homogeneous or unhomogeneous density and signal intensity, well-demarcated boundary on T2-weighted images.

软组织内难以定性的钙质样高密度影：位于骨外软组织内、软组织肿块内部或边缘，CT上呈斑点状、不规则条块状钙质样高密度影，边界清楚或，不清楚。结果57例骨髓炎病人中，54例行CT检查，14例行MR检查。

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。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
