案例背景

本案例节选自主流新能源乘用车完整用户使用手册，内容涉及冬季轮胎使用规范、雪地防滑链安装要求、防滑链行车安全提示三个板块，属面向普通车主的安全指引类文本。该文本兼具科普说明与强制性安全约束双重行文特征，既囊括轮胎规格、花纹深度、链体厚度等标准化车辆参数，也覆盖低温行车、冰雪路况、底盘部件防护等实操场景。原文语言简洁直白，多以短句罗列操作禁忌与使用标准。译文需兼顾家用汽车说明书的通俗阅读属性，同时统一汽车零部件行业术语，既完整保留全部安全限定数值、硬性操作要求，又不丧失原文的约束信息。

Ø 原文与译文

Ø 译文解析：

该文本翻译遵循车辆外文手册统一行文风格，板块标题、提示标识格式规整统一，段落内部以短句排布，契合海外车主快速浏览阅读习惯。针对中文多短句表达，译文采用基础陈述句简化复杂从句，摒弃过于学术化的书面词汇，兼顾可读性与规范性。各类参数限值、安装操作、风险警示等核心技术信息完整对应原文，无增删或曲解；汽车零部件、轮胎专业指标采用行业通用固定译法，全篇术语保持一致。原文中分条罗列的使用禁忌与安全提示，译文沿用分层排布结构，逻辑清晰，区分轮胎选型、防滑链装配、行车操控三类不同场景，便于使用者快速定位对应操作指引。

1) 本段翻译难点主要为车载通用术语统一和句式语体适配两方面。该文本包含轮胎参数、使用工况、安全规范等专属汽车术语，需遵循车企官方手册的固定译法，保证专业度统一。同时，中文说明句式直白通俗，易出现翻译口语化、句式生硬等问题。译文需兼顾通俗易懂的阅读属性与汽车手册严谨规范的书面特质，准确还原温度阈值、轮胎参数、速度限制等关键使用规范，规避语义偏差，保障用户使用指引的精准性。

Winter Tires

Winter tires deliver superior grip on snow-covered road surfaces. Their specially formulated rubber tread is less susceptible to low-temperature conditions and delivers outstanding braking performance, thus enhancing driving safety.

Usage Recommendations

Winter tires are recommended for driving on icy and snow-covered roads when the ambient temperature drops below 7 ℃. Once the temperature rises above 7 ℃, replace them promptly with summer or all-season tires to maintain safe driving and optimal vehicle performance.

When fitting winter tires, select models matching the vehicle’s original factory specifications, including load index and speed rating.

Winter tires must feature sufficient tread depth. A minimum tread depth of 4 mm is required; usability in winter conditions will be compromised if the tread depth falls below this threshold.

Winter tires and summer tires are engineered for the unique acceleration and road conditions of their respective seasons. Using them outside their designated seasons may result in reduced tire adhesion and degraded braking capacity.

Winter tires carry a lower maximum speed rating, so the stated maximum speed must never be exceeded.

After winter tires are mounted, inspect and adjust tire pressure to match the factory-recommended inflation pressure.

AI译后编辑要点：

(1) 将superior grip、specially formulated tread等书面化词汇，替换为简洁通俗的通用表达；同时把Usage Recommendations调整为车企手册常用的Usage Tips，契合车辆说明书轻量化、易读的行文风格；

(2) 还原原文基础表述，规避过度翻译问题。删除额外增补的optimal vehicle performance、factory-recommended等原文无对应语义的修饰内容，严格保留中文原文语义，不随意增删技术信息，保证译文忠实度。同时统一轮胎参数术语写法，全文表述保持一致；

(3) 将复合长句、条件状语从句简化为短句结构，删除冗余的阈值说明与专业修饰，适配中文原文简洁直白的警示说明风格，兼顾文本完整性与大众阅读的通俗性；

(4) 统一句式语态，遵循常规说明文书规范。摒弃复杂的分词状语、转折句式，改用常规陈述句与被动句式，还原中文原句平实的说明逻辑，保留原文基础语义，契合普通用户手册的表述习惯。

2) 本段翻译难点主要包含汽车专用零部件术语、法规表述与句式通俗化平衡三方面。文中包含细枝防滑链、轮罩间隙、授权服务店等固定汽车术语，需选用车企手册通用标准译法；同时，地方交通法规条文转述的翻译易出现生硬法律英语。原文多条安全警示为中文短句结构，为匹配普通车主的通俗阅读需求，需简化复合长句，删减冗余修饰，在完整保留安装厚度限制、咨询渠道、禁止干地行驶等安全硬性要求的前提下，兼顾文本可读性。

Snow Chains

Snow chains are only for emergency use or when driving through specific regions where their use is mandated by law.

Install snow chains on the front wheels. Exercise extra caution when driving a vehicle fitted with snow chains on icy and snow-covered roads. Certain types of snow chains may damage the vehicle’s tires, wheels, suspension and body. Fine-link snow chains are recommended, and the thickness or diameter of chain links shall not exceed 5 mm to maintain sufficient clearance between the tires and other components inside the wheel arches.

Carefully check and read the component assembly diagrams and other instructions provided by the snow chain manufacturer.

Consult an authorized BYD service dealer where you purchased the vehicle before purchasing and fitting snow chains.

To minimize wear on tires and snow chains, avoid driving with snow chains mounted on roads free of ice and snow.

AI译后编辑要点：

(1) 将where their use is mandated by law改为where they are permitted by laws，删去冗余的driving through特定修饰，弱化生硬法务语体，匹配车主手册表达习惯，语义核心不变；

(2) 调整专业部件表述，将wheel arches替换为hubcap，将sufficient clearance简化为enough space；同时改写链体尺寸描述句式，去掉专业限定词chain links，降低阅读门槛，符合普通用户认知水平；

(3) 优化长句拆分与语序，调整组装图说明句语序。将状语后置，拆分初版多层复合句；改写授权门店长难定语从句，用or并列dealer与service provider，表述直白易懂；

(4) 精简冗余书面词汇。替换avoid driving with snow chains mounted为简洁的do not travel with snow chains，删减重复的vehicle限定词，去除技术手册的偏正式措辞，整体行文更简洁流畅。

3) 本段翻译难点在于兼顾专业规范性与通俗可读性。文中包含车速限值、车轮抱死制动、底盘部件干涉等汽车安全专业表述，数值与硬性操作要求不得出现语义偏差；原文多条警示为并列短句，直译易出现冗长复合句式。同时，该段存在两处逻辑处理难点：一是两种限速取低值的法律化表述；二是异响与底盘部件干涉的因果关系转换。翻译时既需保留全部安全约束条件，又要简化句式，降低普通车主阅读理解门槛，在技术严谨性与与大众可读性之间取得平衡。

Friendly Reminders

After fitting snow chains, the driving speed shall not exceed 30 km/h or the lower limit speed specified by the snow chain manufacturer, whichever is smaller.

Drive with caution and watch out for road bumps, potholes and sharp turns, all of which may cause the vehicle to bounce.

For vehicles equipped with snow chains, sharp turns and locked-wheel braking should be avoided. Reduce speed before entering a bend to prevent loss of control and accidents.

Install snow chains symmetrically on the left and right wheels, and remove them immediately after leaving snow-covered road surfaces.

If abnormal noise is heard from the snow chains, pull over safely and inspect components including the suspension, vehicle body and brake lines to confirm no interference with the snow chains.

AI译后编辑要点：

(1) 将 Friendly Reminders精简为行业手册通用单字标题 REMINDER，简化标题与书面化措辞；将fitting、equipped with替换为install、with，删减冗余修饰词汇，弱化工程文档的偏生硬语体，更适配车主指南阅读习惯；

(2) 重构异响故障描述逻辑，将初版长句的“分步检查部件、确认无干涉”，调整为先点明异响代表链条剐蹭底盘零件，再给出停车检查指令，使因果逻辑更直观。省去复杂定语从句后，车主可快速抓取风险信息；

(3) 优化语句语序与通俗表达，调整防滑链拆除一句，将leaving snow-covered road surfaces改为通俗表述back on the snow-free roads；统一将sharp turn替换为curve，简化多层限定句式，行文简短直白。
