Thus, we've decided to put the new Google search through the wringer. We took the developer version for a spin and compared it to not only the current version of Google Search, but to Bing as well.

因袭，我们决定把这一新的谷歌搜索引擎技术投入运行，让测试版本作自我运行并且把他们与谷歌搜索的最新版本和必应同时比较。

Experimental results show that the zero effort miss vector calculated by using approximate formulas is close to the real miss vector. Under the conditions of small initial errors, the satisfied results can be obtained by approximate function. The zero effort miss vector obtained can be used for the preliminary design and analysis of kinetic interceptor guidance.

测试结果表明该近似算法得到的零控脱靶量与真实值比较接近，在较小初始偏差条件下，简化的近似计算公式能给出满意的结果，所得零控脱靶量可用于空间动能拦截制导系统的初步设计与分析。

The compound eyes of cotton bollworm showed higher sensitivity under similar conditions; for one insect, the compound eyes were more sensitive to light in the evening than at the daytime, with dark eyes had higher sensitivity than bright eyes;(4) The comparison of the transition between different adaptative state at different time showed that the compound eyes of cotton bollworm showed more obvious daily rhythm.

在相同条件下，棉铃虫复眼表现出更强的敏感性；同种昆虫复眼夜间比白天敏感，暗眼比亮眼敏感；（4）对不同测试时间复眼明暗状态转化的比较表明，棉铃虫复眼的ERG反应具有更强的昼夜节律性。

They tested only one dose, which was larger than a human would comparatively use, Agarwal said, and after eight weeks, tumor volume in treated mice were reduced by 44 percent and tumor weight by percent, compared to control animals.

他们测试了，只有一针，其中大于一个人会比较使用，加瓦尔说，在八周后，肿瘤体积在治疗组小鼠分别下降了44 %和肿瘤重量%，较对照组动物。

An AlTiN ceramic coating was deposited on the surface of biomedical Ti6Al4V alloy by High Ionic Pulse technology. The properties of biofriction and wear of AlTiN coating in simulated serum lubrication at 37℃ were investigated and compared with that of non-coating Ti6Al4V alloy.

采用高度离子化脉冲工艺在医用钛合金Ti6Al4V表面制备AlTiN涂层；在摩擦磨损试验机上测试了涂层在37℃的模拟人体生理血清液润滑条件下的摩擦磨损性能，并与之和未经涂层的Ti6Al4V合金作比较。

The approval was based on data from four double-blind, randomized trials that compared the antianginal and anti-ischemic efficacy of ivabradine with placebo, atenolol, and amlodipine in 3,222 patients. Results obtained using a standardized exercise tolerance test showed that twice-daily administration of ivabradine, 5 and 7.5 mg, significantly decreased the incidence of anginal episodes.

这项核准案是根据4项双盲随机分派试验结果，这些试验针对3，222位病患，比较Ivabradine相较于安慰剂、atenolol、及amlodipine治疗心绞痛与减少心肌缺血的效果；以标准运动耐受性测试所得到的结果显示，每天投予2次5或是7.5毫客的Ivabradine可以显著地降低心绞痛发生的次数。
