Compared of the efficiency of treating heavy metals in FGD wastewater with NaOH, Ca_2 and Mg_2. It indicated that NaOH was much efficient for precipitated waste water; Ca_2 was much efficient for unprecipitated waste water, the removal efficiency reached 98.4%. With the increasing of the main ion of Ca~2+, Cl~- in FGD wastewater, the efficiency decreased. It decreased 60% for the removing of Mn and 10% for Zn, Cd and Ni. The rectification coefficient token the Ksp of practical wastewater because it quite different with theoretic Ksp at different pH; the theoretic and practice addition were proportioned and it commonly reached 1:300.The precipitation efficiency of Na2S at different pH and the effect of Ca2+ was determined.

比较了NaOH、Ca_2和Mg_2处理脱硫废水时重金属的去除效果，分析了Ca~(2+)、SO_4~(2-)和Cl~-等主要离子的影响，结果表明：NaOH和Ca_2能有效处理脱硫废水中的重金属；对澄清废水而言，NaOH效果较好，对于未澄清废水而言，Ca_2效果更好，但去除废水中重金属的效率都能达到98.4%；随着Ca~(2+)、Cl~-等主要离子浓度的增大，中和作用去除重金属的效率降低，Mn最大降低60%，Zn，Cd，Ni降低10%左右；实际重金属浓度和用理论Ksp计算所得值差别很大，通过校正系数能有效计算实际重金属浓度；实现相同pH时氢氧化物的理论和实际投加量成一定比例，最大可达1：500。

But after comparing them, the author thinks that the user cost approach is better to calculate the self-value depreciation of the unrenewable resources.

于是，使用者成本法就成为对非再生资源开发利用中价值折耗进行计量的比较可行的方法。

Methods Ultrasound, introvenus urogram, retrograde pyelography, CT, magnetic resonance urography and transurethral ureteropeyloscopy were performed, and the accuracy rate was evaluated.

方法在诊断肾盂癌时采用B超、静注尿路造影、逆行性肾盂造影、CT、泌尿系磁共振水成像、输尿管肾盂镜检查等多种方法，比较各种方法对早期肾盂癌诊断的准确率。

Experimentation shows the effect on soil water, soil temperature and seedling growth in an arid environment of liquid film, compartmentalisation and their combination.

通过盆栽和田间实验，比较了液态地膜和植生带及其配合使用对土壤水分和温度及玉米成苗的效应。

Masculinity, explains Rupp, offers the promise of a nice set of genes but at the risk of reduced investment in offspring. This brain activity, measured with functional magnetic resonance imaging, was seen even though the women said they didn't find the picture more attractive than the feminized version.

Rupp解释道，阳刚之气虽然具有一组不错基因的预示，但是还说明会有对后代抚养做出的投入减少的风险）采用功能性磁共振成像手段侦测到的这一大脑活动即便当女性们称自己并不觉的最男性化照片看上去会比较为女性化的更有魅力时同样被观察到了。

Haze's impact is that hazed mask haze is still in use has not been caused by the timely detection of loss of product yield as well as the mask to repair due to haze resulting product cycle delay.

在晶圆厂内Haze的产生是比较正常的现象，它对生产上的影响是haze 的光罩没有被及时发现仍在使用造成产品良率的损失以及光罩因haze 去送修造成产品生产周期的延迟。

Because Hawkins doesn't like to be leashed just yet, he would best suit a home in the country, away from fast traffic, where he could be treated as an inside-outside dog without the use of a leash. His adopter would need to patient and understanding and be able to accept unrequited love, but we are certain the rewards and joy from providing Hawkins and Long John a happy home will far outweigh any inconveniences.

因为霍金斯很讨厌带著狗鍊，所以对他最好的环境是在比较乡下，也没太多车的地方，这样可以不用牵绳并训练成室内或户外的狗收养霍金斯会需要更多的耐心和宽容包涵的心，并且需要付出更多的爱心，因此，给霍金斯和Long John一个快乐温暖的家是很重要的。

First, the background spectrum is subtracted from experimental one; Second, by the spectrum stripping, the counts came from partial energy deposition of incidence photon in HPGe crystal, such as Compton scatting or pair production; the next, transform the experimental spectrum to the incidence photon flux spectrum.

实验数据的处理过程有三步：1 从实验谱中减掉本底谱；2 实验谱中分离掉各种能量的入射光子在晶体中的部分能量沉积(康普顿散射、电子对效应)：3 处理过的实验谱转成入射光子通量谱。比较结果显示，在本实验中，模拟谱对实验谱的总计数相对偏差不大于20%，两者基本符合。

Color analyzer is used to measure the effects of mixing the color of both performer's make up and stage lighting, in order to explore the influences of different stage lighting on foundation and eye shadow colors. By comparing combinations of stage lighting and colors, we aim to provide an overall modeling design in performing art for reference.

本研究目的在探讨表演人员之化妆色彩与舞台灯光混成效果，应用色彩分析仪器进行化妆眼影量测，目的在探讨不同的舞台灯光颜色对表演人员化妆粉底及眼影色彩之影响，希望藉由不同灯光颜色与角度与化妆色彩的组合比较，可提供教学研究及展演艺术之参考。

In field of cotton as CK, with the 20-year-old almond tree intercropping cotton of the photosynthetic characteristics yield and soil nutrient a comparative study, results showed that:①almond and cotton intercropping cotton yield great influence mainly reflected in the decrease of Harvest lants、 Harvest bolls and Total bolls, thereby affecting the Seed cotton yield and lint yield, Inside of crown almond , Tow meter outside of crown almond of the Seed cotton yield were contrasted respectively comparatively having decreased 66.92% and 42.78% by degrees.

以大田棉花为对照，与20年生扁桃树下间作棉花的光合特性、产量及土壤养分进行比较研究，结果表明：①扁棉间作对棉花的产量影响很大，主要表现在间作减少了亩株数、亩铃数和单株成铃数，进而影响到了子棉和皮棉的亩产，扁桃树树冠内侧、树冠外侧2米处的子棉平均亩产分别较对照递减了66.92%和42.78%。
