不理想的

It is ideal for detecting changes to short sequences of bytes; however, because there are only 232 possible checksum values, and because it is not cryptographically secure, the likelihood of a collision is high, giving the attacker a realistic chance to replace code without changing the checksum.

用它检测字节短序列比较理想；但由于只有2的32次方个可能的校验和值，而且不具密码安全性--碰撞可能性高，所以给了入侵者一个可实现的机会，不改变校验和而替换代码。

The results showed that the ultrasonic extraction is a rather ideal method of extracting red P. tha fortuneana pigment. Cyanidin3glucoside can be hydrolysised to aglycon cyanidin under the conditions of 90℃, 9％HCl and 11min.Silica gel thinlayer chromatography with developping agent benzene∶ethyl acetate∶formic acid = 2∶2∶1 is better to separate cyanidin. Cyanidin is stable to heat and light, unstable to Zn2+ and Fe3+ and Cu2+, insensitive to Co2+ and Bi3+, befitting to acidic condition.

结果表明，超声提取法是提取火棘红色素的较理想方法；矢车菊素3葡萄糖苷在90℃和9％盐酸中水解11 min，可以顺利得到其苷元矢车菊素；以苯、乙酸乙酯、甲酸(2∶2∶1)为展开剂的硅胶薄层层析法分离矢车菊素的效果较好；矢车菊素对热和光较稳定，在酸性条件下稳定，对Co2+和Bi3+不敏感，对Zn2+、Fe3+、Cu2+不稳定。

The activity coefficients presented in Tables 4 and 5 indicate that the dipropyl ether (1)+ 2-ethoxyethanol (3) system shows positive deviations from ideal behaviour and that the 1-propyl alcohol (2)+ 2-ethoxyethanol (3) system exhibits no deviation from ideal behaviour and no additional azeotropes are present.

表4和表5所示的活度系数表明，&二丙醚+2-乙氧基乙醇&体系与理想模型表现出正偏差而&1-丙醇+2-乙氧基乙醇&体系则无偏差，并且不存在其他共沸物。

Now the water as solvent adhesives, innoxious, nuisanceless, fire, but this is limited to ofmaize host materials can distribute a wide range of polymer resins, and polymer-coated plastic film, equipment, and so on are demanding, stability of less than ideal.

现已开发出以水为溶剂的粘合剂，其无毒、无公害、不燃烧，但这种粘合剂主体材料只限于能在水中分散的各类高分子树脂，而且对塑料薄膜、覆膜设备等均要求较高，粘合性能的稳定性不太理想。

In the research on assessment of inspectability, a uncertainty model and uncertainty propagation model of Virtual Coordinate Inspecting System is setup according to the feature that parts to be inspected in Virtual Coordinate Inspecting System are considered as ideal parts.

在可测量性评估方法的研究中，本文从虚拟坐标测量系统中的零件被当作理想零件这一特点出发，建立了虚拟坐标测量系统的不确定度模型及其不确定度传递模型。

Methods:during the year 2003 to 2006,3298 patients with vaginal delivery received 2 kinds of skin preparations.retrospective study was conducted to investigate the effect of skin preparation methods on the healing of mediolateral episiotomy.rerults:there was no different effect on the wound healing of mediolateral episiotomy between the 2 kinds of skin preparation.conclusions:non-shaving method has no adverse effect on the sterilization of operation field in vaginal delivery.moreover it can save the time of nuring,lower the costs,ease the uncomfortable feeling .therefore,we consider the non-shaving method has advantage over the shaving one.the former is simple and effective which is an ideal way to simplify nursery procedure and spare nursery resource.

收集我院2003年至2006年间共3298例阴道分娩的产妇采用两种不同的备皮方法，观察两种备皮方法对会阴侧切伤口的影响进行回顾性对比分析。结果：两种备皮方法对会阴侧切伤口的愈合影响无明显差异。结论：不剃毛的会阴备皮方法对阴道分娩的手术野消毒无不良影响，并且能够节省护理操作时间、降低产妇费用、减轻产妇不适，所以不剃毛的备皮方法优于剃毛的备皮方法，不剃毛的备皮方式简单而有效，是简化护理工作程序及节省护理人力资源的理想办法。

This situation is not ideal, but it is better than stopping in the middle of a passage to think what comes next! However motoric memory is not reliable, and we must endeavor to reinforce it with the other three ingredients.

这种情况并不是很理想，但至少比在音节中停顿下来思考要好，然而运动记忆也不是完全可靠的，我们必须用其它三种方法强化运动记忆。

Had Ravana stepped into the hut crossing LR himself Sita would have had the real vision of him as the dreaded rakshasa, and there would be no Ramayana and there would be no lesson for mankind.

已茹阿瓦纳跨进小屋过境表LR自己悉他将有真正的理想他是可怕的rakshasa ，并就不会有罗摩衍那和就不会有人类的教训。

Recently, some manufacturers developed so-call specialty lenses, eg. Toric lenses, Multi-Focal lenses….etc. However, due to the local regulation constrain, those products are prohibited to do mass media advertising, so the sales and brand awareness of those products are not in good shape.

而近期又有厂商推出所谓的特殊功能隐形眼镜；如散光抛弃式隐形眼镜、老花抛弃式隐形眼镜等等，但碍於国内医疗法规的限制，均不能在大众媒体上作广告行销，而使得产品之知名度不足，所以在商品的推广及销售上都不甚理想。

The mtDNA COI, mtDNA COⅡand mtDNA Cyt b genes of different Trichogramma species and different geographical populations of the same Trichogramma species were sequenced, and the genetic distance and phylogenetic relationships of Trichogramma were respectively established based mtDNA gene sequences.

本研究成功测得了多种赤眼蜂不同种和不同地理种群mtDNA（COI、 COⅡ和Cyt b ）的基因序列，对赤眼蜂mtDNA基因序列从遗传距离和系统进化树进行分析，结果表明3个基因序列均适合赤眼蜂种一级的分子鉴定，不能用做种下阶元的区分，同时确定mtDNA Cyt b 基因为赤眼蜂蜂种鉴定的理想基因序列。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
