Part 2. Measurement of macular light sensitivity and FM 100-hue test in normal prese- nium and geratic people. The macular light sensitivity 、macular foveal light sensitivi- ty in 64 (82 eyes) and hue discrimination in 75 (100 eyes) normal presenium and geratic people were examined with macular threshold (white、red、blue and green color light) program of the Humphreh Field Analyzer and FM 100-hue test respectivity. The re- sults showed that the light sensitivity in four color light threshold was all declined with age. The mean error score square of each spectral region and whole spectral was increased with age, the loss of light sensitivity and hue discrmination was a linear correlated with age. The light sensitivity of the different field was compared, except blue color light threshold, the light sensitivity was decreased with the increasing of the eccentricity, white and red color light threshold in the inferior field showed lower sensitivity than that in the superior field.

二、老年前期及老年期正常人的黄斑阈值及FM100-色调试验检测采用Humphrey视野分析仪黄斑阈值程序和FM100-色调试验仪分别对82例（82眼）和75例（100眼）老年前期及老年期正常人进行了黄斑光敏度、黄斑中心凹光敏度及色调分辨力的测定，结果显示四种色光阈值的光敏度均随年龄增加而降低，FM100-色调试验各个色区及全色区错误记分方根随年龄增加而增高，光敏度及色调分辨力的降低与年龄呈线性相关；不同视野的光敏度比较，除蓝色光阈值外，光敏度均随视野偏心度的增加而减少，视野的上半部光敏度较下半部低；视野的鼻侧与颞侧及各象限的光敏度无显著差异。

Methods Suspension quantitative germicidal test and animal toxicity test were used to carry out experimental observation.

方法采用悬液定量杀菌试验和动物毒性试验方法进行了试验观察。

The experiments included compressive strength, flexural strength, shear strength of sand grouts, stability and fluidity of net grouts.

试验内容包括砂浆的单压、抗弯、抗剪强度试验以及净浆稳定性和流动度试验。

The experiment uses 100% city garbage melting slag instead of nature macadam and sand to make concrete specimens, under homoiothermal (20±2)℃ and constant humidity relative humidity (60±5)%, which dry and shrink freely 180d. The results show, comparing with common concrete specimens, whose drying shrinkage length valuable rate and mass loss rate change a little.

试验以100 %城市垃圾熔渣骨料替代天然碎石和砂子制备城市垃圾熔渣混凝土试件，在恒温(20±2)℃，恒湿相对湿度(60±5)%的试验室内使混凝土试件自由干燥收缩180 d，试验结果，城市垃圾熔渣混凝土试件与对比用的普通混凝土试件相比，干燥收缩长度变化率以及质量损失率相差不大。

It is pointed out that the methods for the hydrogeological tests of bedrock and the methods for the analysis should be used according to the seepage ability to obtain the reliable and accurate results.

指出钻孔中基岩的水文地质试验应根据不同的渗水能力及时调整试验方法，运用相应的分析方法，以得到最为可靠的试验结果。

SD rat, rabbit and guinea pig were used to test acute toxic, stimulative, and hypersusceptible reaction in treated by compound Daihuang ointment, respectively.

利用健康SD大鼠进行皮肤急性毒性试验；用健康大耳白兔进行皮肤刺激性试验；用健康豚鼠进行皮肤过敏试验。

We identified reports of clinical trials that compared computed tomography-based and imageless naigated arthroplasty with conentional unicompartmental or total knee arthroplasty, regardless of the underlying condition or disease.

我们找出了以断层摄影术为基础的临床试验和不依赖影像的关节成形术导航的临床试验的比较报告，这些临床试验或者是常规分区膝关节表面置换术，或者是全膝关节表面置换术，但是未考虑患者潜在病情或疾病本身情况。

The antifatigue function of more than forty kinds of insect,fungi,bacteria and algae was studied and sifted first in this study by detecting swimming endurance and biochemical indexes. Then,in order to choose the better ones from the compoud additives formulas composed of L-carnitine, taurine, octacosanol,vitaminE and insectA ,a cross design experiment was done. InsectA was discovered in the first experiment that it greatly improved the antifatigue function in mice. Finally, the acute toxicities, thirty-day feeding effects and the mechanisms of No. 1 antifatigue compoud additives(No.1ACF) were studied.

本研究首先通过小鼠游泳耐力试验和血液生化指标的测定对40余种昆虫、菌藻的抗疲劳作用进行了筛选；在此基础上，应用正交设计方法对以L-肉碱、二十八醇、牛磺酸和本实验筛选出的抗疲劳功效较好的昆虫A为原料的配方进行了抗疲劳作用筛选，并对筛选出的最佳配方，即抗疲劳复方添加剂1号配方进行了小鼠急性经口毒性试验、30天喂养试验和抗疲劳作用机理研究。

A 8-week growth experiment was conducted to estimate the quantitative requirement of tourmaline for GIFT strain of Nile tilapia [initial body weight(15.90±0.1) g] by feeding five isonitrogenous(33%) and isoenergetic(17.2 MJ/kg) diets containing five levels of tourmaline at 0, 0.5％, 1%, 2% and 3%, respectively.

试验以（15.90±0.1） g的吉富罗非鱼为试验对象，在等氮（33%）等能（17.2 MJ/kg）的基础上，在其日粮中分别添加0、0.5％、1％、2％和3％的固相负离子粉，在循环水养殖系统中进行8周的生长试验。每种饲料设计3个重复，每桶放鱼30尾。

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。
