低降

The atom ratio of B/N (1. 01) is almost equal to full stoichiometry and the volume fraction of c-BN is equal to 88%.

由第一步到第二步，工作气体由氩气变为氩气和氮气的混合气体，同时偏压和温度降为较低的值。

Isomap is a nonlinear dimensionality reduction method proposed and based on the theory of manifold. It not only can reveal the meaningful low-dimensional structure hidden in the high-dimensional observation data, but can recover the underlying parameter of data lying on a low-dimensional submanifold.

Isomap是提出的一种有效的基于流形理论的非线性降维方法，它不仅能够揭示高维观察数据的内在结构，还能够发现潜在的低维参教空间。

Example 30-6 contains an A major chord as VI in C major. Note that this chord does not function as we might expect as V of II. Instead, it fulfills another basic function of the submediant triad: to lead down in 3rd from I to IV. Rising C to C# give emphasis to the chord and intensifies the "Searching" quality of these bars

而他被赋予的是下中三和弦的另一个功能：从I到VI的降3过度作用（书里的意思是说按照由高到低的方式排列I-IV，让VI来作一个过度和弦）把C变为#C给了这个和弦以重点并且加强了这几小节的锐利性和穿透性。

A gear H62 which made in yellow brass with the same mode number m=0.34, 2mm thick and had a center hole, when the gap get C=0.5%t , and punched with compound punching die, and the dimension accuracy reached IT7, the part have a flat surface ,the verticality of tangent plane reached 89.5°, its roughness Ra magnitude are 12.5μm, height of burr are 0.10mm; and the punching part are punched with progressive die, the gap C=7%t , initial accuracy are IT11, and have an more rough surface, even can see the gap with eyes.

例如料厚t=1.5mm的H62黄铜冲裁件，选用C≤40%t单边Ⅰ类小间隙冲裁比选用C≤8%tⅢ类大间隙冲裁，冲件固定误差将加大40%～60%，精度至少降一级。此外，采有无搭边排样，冲件的误差要远大于有搭边排样冲件。无搭边排样冲件。无搭边排样冲件的精度低于IT12级，而多数有搭边排样的冲件精度在IT11～IT9级之间，料厚t＞4mm的冲件，尺寸精度会更低一些。

The sucrose content of the low R/S line "NAU-LR-04" was higher than those of three highR/S lines at all stages, while the fructose content was lower in "NAU-LR-04". Changes ofactivities of sucrose synthase were similar to sink activities in all the lines, and theactivity of SuSy in low R/S line is higher than those of high R/S lines.

结果表明，不同根冠比肉质根的库活性变化基本一致，"破肚"后一周内达到最大；可溶性总糖、果糖、蔗糖含量初期下降，"破肚"期降至最低值，其中低根冠比品系'NAU-LR-04'蔗糖含量一直高于其它高根冠比品系，而其果糖含量则相对较低。

So the higher the reduction in systolic blood pressure, the higher the reduction of risk.

所以收缩压降的越低，患者的患心血管疾病的危险性就越小。

We seem una ble to think reason clearly or active with decision.

今天主持公道的知识界奇怪地保持沉默，而我们的政界领导人的水平则已降到很低的程度。

Linxia in the valley, and with little flat ground and the high-lying south-west, north-eastern low, from southwest to northeast in descending, the basin was tilted, and an average of 2000 meters above sea level.

临夏内山谷多，平地少，地势西南高，东北低，由西南向东北递降，呈倾斜盆地状态，平均海拔2000米。

At the same time, do not drop too low air temperature, because a larger temperature difference is often out of place, too vasoconstriction, but also easy to cause a sudden increase in blood pressure and other factors of instability.

同时，不要将空调温度降得过低，因为常常出入温差较大的地方，血管收缩过快，也容易突然造成血压升高等不稳定因素。

A Decomposition Forward Support Vector Machine algorithm for large scale samples learning and a new dimension reduction model based on Independent Component Analysis were proposed. The calculational complexity is lower than that of the traditional chunking algorithm and the standard SVM.

提出一种基于大样本学习的分解向前支持向量机算法和一种新的基于独立成分分析的降维学习模型，其算法的复杂度比传统块算法和标准SVM低。

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。
