Paraphrase: It was an evening just as normal as other evenings when a car coming in the other direction was no longer manageable, broke through the guard rail and hit two other cars before hitting violently against his car front to front.

这是一个含有 when 引导的定语从句的复合句。句中 no 放在一个形容词的比较级前强调某事物的程度、大小或范围，有时用来表示惊讶、羡慕等情绪。no+比较级+than 结构表示&不比…更&，强调两者都不行。而 not +比较级+than 结构则表示&不如&。

There are, however, no wide-accepted molecular parameters taken as a reference and no precise γ and A_D obtained simultaneously so far.

本论文报道我们获得的自然丰度下N~(16)O的中红外LMR光谱，并采用最新的联系各同位素分子参数的标度函数将所有已发表的光谱数据和我们测量的实验数据实现统一的标识分析，通过对所有数据的完整一体的最小二乘拟合，得到了迄今为止最完备、最精确的~mN~nO(m=14，15；n=16，17，18)系列分子的结构参数，这些参数的精度与文献结果相比提高了1-2个量级，其中许多参数都是首次获得的。

Many studies have been accomplished byvarious kinds of spectroscopic techniques with some important molecularparameters determined. There are, however, no wide-accepted molecular parameterstaken as a reference and no precise 〓 and 〓 obtained simultaneously so far.

人们运用各种光谱技术对NO在各波段的光谱进行了大量的研究，获得了一些重要的分子结构参数，但却没有一组公认准确统一的分子参数可供使用，也不能同时获得分子参数〓和〓。

Furthermore, the effect of single electron transfer on the dissociation of N-NO bond was also investigated.

此类化合物N-NO键的与〓差别较大，说明它们是储NO分子的好的模型化合物。

The results showed that (1) all the arteries tested had tachyphylaxis to peptidergic agonists;(2) the desensitization of the arteries tested to catecholamines was uneasy except BA;(3) the desensitizations to AⅡ, AVP and PE were homologous;(4) the endothelium-EDRF -cGMP pathway had no contribution to the tachyphylaxis of PA to AⅡ and AVP;(5) membrane receptor cycling (internaliation and re-insertion) contributed only in part to homologous desensitization;(6) there was no change in the function of voltage-dependent Ca〓 channel during desensitization to AⅡ and AVP;(7) some changes in G protein occurred during homologous desensitization;(8) the most surprising finding was that the caudal arterial smooth muscle of stroke-prone spontaneously hypertensive rat showed tachyphylaxis to α〓-adrenoceptor agonist PE, while the tachyphylaxis of pulmonary artery of SHR was not changed compared with that of Wistar rat.

脱敏是消除效应的一种有效方式。因此，研究不同血管对不同激动剂脱敏的差异及阐明脱敏的机制，有助于阐明血管活动个性化的机制。研究表明：血管对肽类激动剂的脱敏方式为快速脱敏，而对儿茶酚胺类激动剂不易脱敏；血管对肽类激动剂和儿茶酚胺类激动剂表现为同源脱敏；内皮-NO-cGMP通路不参与肺动脉对AⅡ和AVP的快速脱敏；用PAO抑制膜受体的内在化只能短暂抑制脱敏的发展，提示用膜受体数目的下调说不能完全解释同源脱敏；血管对AⅡ和AVP脱敏后VSMC细胞膜电压依赖性钙通道功能无改变；CA对AVP脱敏后GTPγS的量-效曲线下移，说明有G蛋白的变化，但这种变化并非G蛋白的亲和性改变；SHRsp之CA平滑肌对AⅡ和AVP的快速脱敏并未减弱，但对PE却表现为快速脱敏，这是我们首次发现的一个非常有趣的现象。

Thereafter, both NO content and NOS activity of testis homogenates were increased.

结果 与对照组比较，糖尿病组血清NO含量升高，NOS活性先升后降；睾丸组织在诱模后NO含量下降，而NOS活性变化不明显，随后两者均呈升高趋势。

NOS also reflect the generation of NO, NOS was measured by a method which the oxidation of oxyhaemoglobin to methaemoglobin by NO is monitored spectrophotometrically. The absorption difference between 401 and 421nm was continuously monitored with a dual-wavelength recording spectrophotometer.

由NOS催化生成的NO与氧合血红蛋白反应生成高铁血红蛋白，反应2秒钟完成同时出现A〓和A〓吸光度的变化，测定该变化，根据此时高铁血红蛋白的摩尔吸光系数即可计算出NOS的比活性。

The free radicals in liver tissue inhibited the synthesis of NO in hepatic injury.

结果 大鼠注射L-Arg后，NO的合成增多，转氨酶及肝组织损伤程度明显降低，注射L-NNA组大鼠肝损伤程度加重，肝组织自由基的测定表明，抑制肝损伤大鼠NO合成，肝组织LPO含量增高而SOD，GSPHX活性降低，SOD，GSHPX协同作用可清除体内自由基。

Further study showed that ryanodine mediated CICR contributed greatly to the secondary NO elevation induced by BK treatment.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
