不改变的

And the solutions of arbitrary time-space elastic force equations of time-space variable system multi-linear vectors all are corresponding constant modulus multi-linear vectors, their time-space moving regular are: only change their directions but do not change their moduluses.

而任何时空可变系多线矢的时空弹性力方程的"解"，都是相应的"常模长多线矢"，它在时空的运动规律是：仅改变方向，不改变"模长"。

First introduced by C.H. Waddington in 1939 to name "the causal interactions between genes and their products, which bring the phenotype into being,"3 epigenetics was later defined as heritable changes in gene expression that are not due to any alteration in the DNA sequence.4

Waddington首先引进以命名"基因和它们的产物间的因果交互作用，并把表现型带入生物"，表观遗传学后来定义为不归因DNA序列任何改变的基因表达的遗传学改变。

Under the Win9x family (Windows 95, 98, and Millennium) it is impossible to get this information accurately, so SoftwarePassport/Armadillo simply uses the total size of the hard drive instead, which can be changed by programs like PowerQuest's PartitionMagic, or by repartitioning the drive (which would necessitate reformatting and reinstalling the operating system as well). Also note that, like the BIOS Information item above, under Windows 2000 and XP it's possible to set programs to use a "compatibility mode" that will effectively tell the program that it's running on a Win9x system, which will change this item.

在win9x家族下(Windows 95， 98， and Millennium)要精确地获得这个信息是不可能的，因此SoftwarePassport/Armadillo只是简单的使用硬盘尺寸的总数，这个可以被改变通过类似PowerQuest's PartitionMagic，的程序，或者通过重新分区硬盘（也需要出重新格式化和重新安装操作系统）同时注意，像是上边的BIOS信息项目，在win2000和XP下，可能设置程序使用&兼容模式&将有效地告诉程序他运行在win9x系统辖，这将改变这个项目。

The xinguang tube time-sensitive, relatively short exposure time, relatively small light permeability to expand; however, as the UV light to rule over the ages, lighting effects, exposure time gradually extended, fine idea is not easy, but deep PIP light permeability to expand it is becoming increasingly damageto, resulting in a traditional version that are the same pair of film on the same printer, after a certain period of time, get the flexo from deep network to a brief network halftoning, also occur when different curves change!

这表示在新平惯时平敏不弱，曝平工夫相差长，平渗放大相差小；但随着UV平惯的忽然老化，平效放松，曝平工夫忽然延不幼，粗不面子不便当不入来，但浅不面子的平渗放大愈发狠恶，酿成古板版那怕是统一副胶片在统一台晒版机上，经过一段期间后，晒不入的刚性版从浅网到浅网的阶调，也会爆发差别的弧线改变！

Previous research has shown that smoking cessation enables better health as well lower medical care utilization. However, previous research usually treated smoking as a time invariant variable and hence can not determine the actual economic impact of smoking as time passes. In addition, previous research differs in research design and limited in duration of follow-up after smoking cessation. Hence it is necessary to conduct a study with longer period of follower-up.

虽然有研究证实戒菸可改善健康状况、减少医疗利用，然而上述研究有些系横断性，有些将吸菸状态设计为不随时间改变(time-invariant)的变项，无法呈现随时间改变的吸菸状态对医疗利用的影响；另外过去研究结果依研究设计、追踪年数不同而有所差异，若能追踪较长的时间，更可厘清戒菸时间与医疗利用间的关系。

The Serenity Prayer : God grant me the serenity to accept the things I cannot change; courage to change the things I can; and wisdom to know the difference.

平静的祈祷：上帝保佑我平静接受的东西我不能改变；有勇气改变的事情我可以；和智慧，知道其中的差别。

Ejector seat levers come in two basic varieties: those that cause a significant visual dislocation (large changes in the layout of tools and work areas) in the program and those that perform some irreversible action .

弹射座椅操作杆有两个基本变形，即造成视觉分布上（对工作区和工具排列的巨大改变）重要变化的行动和造成一些不可逆改变的行动，这两类功能都应该对经验较浅的用户是隐藏的，其中后一个更危险。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
