I'm not sure I fully understand the issue you're trying to describe here. It might be useful to show the mount permissions (mount command or /etc/fstab entries) and working smb.conf configuration perhaps.

Sorry for my bad expression. I create some files in a Linux server and then share them to a windows server with Samba. And then I found a problem—The files’ permission will be reset to 664(rw-rw-r—) after I edit them by windows application(such as Excel).So I wonder what cause this problem occur.
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba,
# read the Samba-HOWTO-Collection. This may be obtained from:
# http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the
# Samba-Guide which is generated daily and can be downloaded from:
# http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
#
#---------------
# SELINUX NOTES:
#
# If you want to use the useradd/groupadd family of binaries please run:
# setsebool -P samba_domain_controller on
#
# If you want to share home directories via samba please run:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory you want to share you should mark it as
# "samba-share_t" so that selinux will let you write into it.
# Make sure not to do that on system directories as they may already have
# been marked with othe SELinux labels.
#
# Use ls -ldZ /path to see which context a directory has
#
# Set labels only on directories you created!
# To set a label use the following: chcon -t samba_share_t /path
#
# If you need to share a system created directory you can use one of the
# following (read-only/read-write):
# setsebool -P samba_export_all_ro on
# or
# setsebool -P samba_export_all_rw on
#
# If you want to run scripts (preexec/root prexec/print command/...) please
# put them into the /var/lib/samba/scripts directory so that smbd will be
# allowed to run them.
# Make sure you COPY them and not MOVE them so that the right SELinux context
# is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts

# ----------------------- Standalone Server Options ------------------------
#
# Scurity can be set to user, share(deprecated) or server(deprecated)

#
# Logon Scrpit let yuou specify a script to be run at login time on the client
# You need to provide it in a share called NETLOGON

#

# browser on your network. Otherwise the normal election rules apply

# elections. The default value should be reasonable

#----------------------------- Name Resolution -------------------------------
# Windows Internet Name Serving Support Section:
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
#
# - WINS Support: Tells the NMBD component of Samba to enable it's WINS Server
#
# - WINS Server: Tells the NMBD components of Samba to be a WINS Client
#
# - WINS Proxy: Tells Samba to answer name resolution queries on
# behalf of a non WINS capable client, for this to work there must be
# at least one WINS Server on the network. The default is NO.

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups.

# --------------------------- Printing Options -----------------------------

# --------------------------- Filesystem Options ---------------------------

# The following options can be uncommented if the filesystem supports
# Extended Attributes and they are enabled (usually by the mount option
# user_xattr). Thess options will let the admin store the DOS attributes
# in an EA and make samba not mess with the permission bits.

# Note: these options can also be set just per share, setting them in global
# makes them the default for all shares
