Wang Fang 32adfdc307 Add Chinese translation for the 2nd batch of the files in storage folder in api-reference.
1. The translation should be first reviewed by technical reviewers;
2. and then by language reviewers.

For the translation for the first batch of files, please see !MR5620 and !MR5613

NVS 分区生成程序
------------------
NVS 分区生成程序帮助生成 NVS 分区二进制文件,可使用烧录程序将二进制文件单独烧录至特定分区。烧录至分区上的键值对由 CSV 文件提供,详情请参考 :doc:`NVS 分区生成程序 <nvs_partition_gen>`
应用示例
-------------------
ESP-IDF :example:`storage` 目录下提供了两个代码示例:
:example:`storage/nvs_rw_value`
演示如何读取及写入 NVS 单个整数值。
此示例中的值表示 ESP32 模组重启次数。NVS 中数据不会因为模组重启而丢失,因此只有将这一值存储于 NVS 中,才能起到重启次数计数器的作用。
该示例也演示了如何检测读取/写入操作是否成功,以及某个特定值是否在 NVS 中尚未初始化。诊断程序以纯文本形式提供,帮助您追踪程序流程,及时发现问题。
:example:`storage/nvs_rw_blob` 
演示如何读取及写入 NVS 单个整数值和 Blob二进制大对象并在 NVS 中存储这一数值,即便 ESP32 模组重启也不会消失。
* value - 记录 ESP32 模组软重启次数和硬重启次数。
* blob - 内含记录模组运行次数的表格。此表格将被从 NVS 读取至动态分配的 RAM 上。每次手动软重启后,表格内运行次数即增加一次,新加的运行次数被写入 NVS。下拉 GPIO0 即可手动软重启。
该示例也演示了如何执行诊断程序以检测读取/写入操作是否成功。
